CM04FD151JO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CM04FD151JO3 is a 150 pF mica capacitor rated for 500 V operation in a radial through-hole package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance and high voltage performance. Mica dielectric capacitors are selected for applications demanding low loss, excellent frequency stability, and reliable operation across extended temperature ranges from -55°C to 125°C. Identifying equivalent substitute parts becomes necessary when managing inventory constraints, addressing supply chain disruptions, or optimizing procurement across compatible product lines within the same manufacturer's portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM04FD151JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 150 pF (exact match required)
• Tolerance: ±5% (matching tolerance band)
• Voltage rating: 500 V (minimum acceptable rating)
• Dielectric material: Mica (material type must remain constant)

Mechanical Parameters:

• Mounting type: Through Hole (PCB assembly compatibility)
• Package configuration: Radial (lead orientation and spacing)
• Lead spacing: 0.142" (3.60 mm) (footprint compatibility)
• Physical dimensions: 0.382" L x 0.209" W, Height 0.358" max (board layout fit)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C (thermal performance envelope)

The CD10FD151JO3F qualifies as a parametric equivalent because it maintains identical values across all electrical, mechanical, and environmental specifications listed above. Both components are manufactured by Cornell Dubilier Electronics and belong to the same product category of general-purpose mica capacitors.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The CD10FD151JO3F substitute part is electrically and mechanically equivalent to the CM04FD151JO3 across all specified parameters. Both components maintain Active product status, confirming ongoing manufacturer support and availability.

Compliance Considerations:

The CM04FD151JO3 carries RoHS non-compliant status and is REACH Affected. The CD10FD151JO3F is ROHS3 Compliant and REACH Unaffected. Selection between these parts must account for end-application regulatory requirements. Applications subject to RoHS3 directives or REACH restrictions require the CD10FD151JO3F. Applications without such constraints may use either part based on inventory and procurement optimization.

Inventory and Availability:

The CM04FD151JO3 maintains 731 pieces in stock. The CD10FD151JO3F maintains 2883 pieces in stock, providing greater availability for high-volume procurement or extended supply chain planning.

Moisture Sensitivity:

The CM04FD151JO3 is classified as MSL 1 (Unlimited). The CD10FD151JO3F is listed as Not Applicable for MSL, indicating no moisture sensitivity constraints for either component in standard handling and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the CD10FD151JO3F be used as a direct replacement for the CM04FD151JO3 in existing circuit designs?

A: Yes. The CD10FD151JO3F is a parametric equivalent with identical electrical specifications (150 pF, ±5%, 500 V), dielectric material (Mica), and mechanical configuration (radial through-hole, 0.142" lead spacing). Direct PCB footprint compatibility is confirmed. Regulatory compliance differences must be evaluated for the specific application.

Q: What are the key differences between these two parts?

A: The primary differences are RoHS and REACH compliance status. The CM04FD151JO3 is RoHS non-compliant and REACH Affected. The CD10FD151JO3F is ROHS3 Compliant and REACH Unaffected. All electrical and mechanical parameters are identical. Moisture sensitivity classification differs (MSL 1 versus Not Applicable), but both are suitable for standard industrial handling.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the CM04FD151JO3 and CD10FD151JO3F share identical dimensions: 0.382" length x 0.209" width (9.70 mm x 5.30 mm), with maximum seated height of 0.358" (9.10 mm). Lead spacing is 0.142" (3.60 mm) for both components. PCB layout and assembly tooling require no modification when substituting between these parts.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 or REACH compliance requirements, the CD10FD151JO3F is the appropriate selection. For applications without such regulatory constraints, either part meets the electrical and mechanical specifications. The CD10FD151JO3F offers higher inventory availability (2883 pieces versus 731 pieces).

Q: Do these capacitors require special handling or storage conditions?

A: Both components are classified as MSL 1 or Not Applicable, indicating no special moisture sensitivity precautions are required. Standard industrial storage conditions (controlled temperature and humidity) are suitable for both parts.

Q: Are both parts actively manufactured?

A: Yes. Both the CM04FD151JO3 and CD10FD151JO3F maintain Active product status with Cornell Dubilier Electronics, confirming ongoing production and manufacturer support.
