The CD10ED750JO3 from Cornell Dubilier Electronics (CDE) is a 75 pF mica capacitor designed for through hole mounting in radial lead configuration. This component operates at a rated voltage of 500 V with a capacitance tolerance of ±5%, making it suitable for precision analog circuits and RF applications where stable capacitance values across temperature extremes are required.
Mica dielectric capacitors are known for their excellent frequency stability and low loss characteristics. The CD10ED750JO3 maintains consistent performance across an operating temperature range of -55°C to 125°C, which supports deployment in both commercial and extended industrial environments. The inherent properties of mica as a dielectric material provide low temperature coefficient and minimal drift over time compared to ceramic or film alternatives in similar voltage classes.
The physical form factor features radial leads with 0.142 inch (3.60 mm) spacing, allowing direct insertion into standard PCB through holes. With body dimensions of 0.370 inch length by 0.201 inch width (9.40 mm × 5.10 mm) and a maximum seated height of 0.339 inch (8.60 mm), this capacitor occupies a compact footprint while maintaining adequate voltage standoff. The radial package simplifies mechanical assembly and provides good thermal dissipation through both leads and body contact.
At 75 pF capacitance, this component serves general-purpose applications including timing circuits, frequency-determining networks, and coupling stages where the combination of moderate capacitance and high voltage rating is needed. The 500 V rating provides headroom for circuits operating at lower voltages where transient protection or safety margins are incorporated into the design. The ±5% tolerance allows for use in applications where tighter selection is not warranted, reducing component cost while maintaining adequate performance for most analog and RF stages.
Cornell Dubilier's CD10 series positions these mica capacitors for reliable operation in general-purpose electronic equipment. The through hole mounting approach facilitates rework and replacement in field-serviceable products, while the bulk packaging format supports moderate-volume manufacturing runs. Engineers selecting components for oscillator circuits, filter networks, or impedance matching stages will find the electrical characteristics and physical format compatible with established board layouts using radial-leaded components.

Replacing Cornell Dubilier Electronics CD10ED750JO3 When a 75 pF 500 V Radial Mica Capacitor Is Constrained by Availability, Compliance, or Layout
Cornell Dubilier Electronics CD10ED750JO3 is a 75 pF, ±5%, 500 V radial mica capacitor used where low capacitance, voltage margin, and stable high-frequency behavior are required. Replacement searches usually arise because of RoHS restrictions, approved-vendor limitations, PCB layout constraints, or the need to qualify a second source without changing circuit behavior.

The correct replacement depends on dielectric behavior, voltage derating, lead spacing, parasitic effects, compliance requirements, and whether mica-to-mica substitution is required or a high-stability C0G/NP0 ceramic capacitor is acceptable.

What the Cornell Dubilier Electronics CD10ED750JO3 Mica Capacitor Defines for a Replacement Baseline
The original Cornell Dubilier Electronics CD10ED750JO3 is a CD10 series dipped mica capacitor with 75 pF capacitance, ±5% tolerance, 500 V rated voltage, radial through-hole mounting, and a 3.60 mm lead spacing. Its operating temperature range of -55°C to 125°C supports use in industrial, RF, timing, filtering, and high-voltage signal applications where capacitance stability is more relevant than bulk energy storage.
Key characteristics that influence replacement selection include:
| Parameter | CD10ED750JO3 Baseline | Replacement Impact |
|---|---|---|
| Manufacturer | Cornell Dubilier Electronics | Same-manufacturer options reduce qualification effort |
| Capacitance | 75 pF | Alternatives should match nominal value unless circuit tuning allows adjustment |
| Tolerance | ±5% | Wider tolerance may shift RF tuning, filters, oscillators, or compensation networks |
| Rated voltage | 500 V | Replacement should meet or exceed working voltage with suitable derating |
| Dielectric | Mica | Provides low loss, good stability, and predictable RF behavior |
| Mounting | Through hole, radial | Lead spacing and body height affect PCB fit and assembly process |
| Lead spacing | 0.142" / 3.60 mm | A mismatch may require lead forming or PCB revision |
| Size | 9.40 mm x 5.10 mm, 8.60 mm max height | Larger replacements may conflict with enclosure or adjacent parts |
| Temperature range | -55°C to 125°C | Alternatives must be checked against operating and storage environment |
| Compliance | RoHS non-compliant, REACH affected | RoHS-compliant substitutions may be needed for current builds |
The mica dielectric is the main reason CD10ED750JO3 is not always replaceable by a general ceramic capacitor. In RF coupling, resonant circuits, snubbers for low-current high-voltage signals, and precision compensation networks, dielectric loss, temperature coefficient, aging, and voltage coefficient can affect final circuit behavior. If the capacitor is part of a tuned network, a replacement should be validated under operating frequency, voltage, and temperature rather than selected only by capacitance and voltage rating.
Candidate Replacement Parts for Cornell Dubilier Electronics CD10ED750JO3 and Where Each Option Fits
Candidate replacements fall into two groups: mica-based alternatives that preserve dielectric behavior more closely, and C0G/NP0 ceramic alternatives that may offer RoHS compliance, broader sourcing, or smaller package options. Mica-to-mica replacement is usually preferred in RF, high-Q, or legacy circuits. C0G/NP0 ceramic alternatives can be suitable where the circuit is less sensitive to Q factor or where production compliance and availability dominate.

Engineering Trade-Offs When Comparing CD10ED750JO3 Replacements and 75 pF 500 V Alternatives
Replacement selection should begin by identifying the capacitor’s role in the circuit. If CD10ED750JO3 is used in an RF tank, oscillator, narrowband filter, or impedance-matching network, mica alternatives should be evaluated first. If it is used for general coupling, small-signal bypassing, or compensation where measured performance margins are broad, C0G/NP0 ceramic alternatives may be acceptable.

TDK FG18C0G2J750JNT06 and Murata RCE5C2H750J0K1H03B are better viewed as engineered alternatives rather than direct equivalents. They can be useful for 75 pF 500 V radial capacitor replacement when RoHS compliance, supply availability, or cost control is the main driver, but final approval should include capacitance measurement, voltage derating review, frequency-response testing, and thermal verification in the actual circuit.
