CMR03F331JOYP Equivalent & Substitute Parts

Part Overview

The CMR03F331JOYP is a 330 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 50 V operation with radial through-hole mounting. This component is classified as Active product status and is ROHS3 compliant. Mica capacitors in this specification are used in general-purpose applications requiring stable capacitance across temperature ranges and reliable performance in legacy and modern circuit designs. Substitute parts may be required due to inventory constraints, supply chain considerations, or specific compliance requirements for end-use applications.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	330 pF	Critical - must match exactly
Voltage Rating	50 V	Critical - must equal or exceed
Tolerance	±5%	Critical - determines circuit accuracy
Dielectric Material	Mica	Critical - defines electrical characteristics
Mounting Type	Through Hole Radial	Critical - determines PCB compatibility
Lead Spacing	0.118" (3.00mm)	Critical - affects PCB footprint
Operating Temperature Range	-55°C to 125°C	Important - defines environmental limits
Package / Case	Radial	Critical - physical form factor

Substitute Part Grouping Explanation

Substitution eligibility for the CMR03F331JOYP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

Capacitance value: 330 pF (exact match required)
Voltage rating: 50 V (minimum requirement)
Tolerance: ±5% (circuit design specification)
Dielectric material: Mica (electrical performance requirement)
Mounting configuration: Through Hole Radial (PCB assembly requirement)
Lead spacing: 0.118" / 3.00mm (footprint compatibility)
Operating temperature range: -55°C to 125°C (environmental specification)

The substitute part CD5FY331JO3 meets all critical electrical and mechanical parameters, enabling direct substitution in applications where the specified parameters are required. Differences in RoHS compliance status and REACH classification do not affect electrical or mechanical compatibility but may influence suitability based on end-use regulatory requirements.

Engineering Selection Recommendations

CMR03F331JOYP Selection Criteria:

Applications requiring ROHS3 compliance certification
End-use markets with REACH unaffected material requirements
New designs targeting current regulatory standards

CD5FY331JO3 Selection Criteria:

Legacy system maintenance and repair where original series compatibility is required
Applications where RoHS compliance is not a regulatory requirement
Inventory availability and supply chain optimization

Both parts are Active product status from the same manufacturer and provide identical electrical and mechanical performance. Selection between these substitutes should be based on regulatory compliance requirements specific to the end-use application and geographic market.

Frequently Asked Questions (FAQ)

Q: Can CD5FY331JO3 be used as a direct replacement for CMR03F331JOYP in new designs?

A: CD5FY331JO3 provides identical electrical and mechanical performance. However, it is RoHS non-compliant and REACH affected, which may not meet regulatory requirements for new product designs. Verify compliance requirements for your specific application and target market before selection.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions (0.272" L x 0.181" W / 6.90mm x 4.60mm), height (0.240" / 6.10mm), and lead spacing (0.118" / 3.00mm). They are mechanically interchangeable on PCBs designed for radial through-hole 330 pF mica capacitors.

Q: What is the significance of the different RoHS and REACH status?

A: RoHS3 compliance indicates the CMR03F331JOYP meets current European Union Restriction of Hazardous Substances regulations. REACH unaffected status indicates the part does not contain substances of very high concern. The CD5FY331JO3 does not carry these certifications. Selection depends on whether your application requires these regulatory certifications.

Q: Do both parts have the same operating temperature range?

A: Yes. Both CMR03F331JOYP and CD5FY331JO3 operate across -55°C to 125°C, providing identical thermal performance characteristics.

Q: Is the capacitance tolerance identical?

A: Yes. Both parts are specified at ±5% tolerance, ensuring equivalent circuit accuracy and performance in applications requiring this tolerance specification.

Q: Can these parts be used interchangeably in legacy equipment repair?

A: Both parts are electrically and mechanically equivalent. However, if the original equipment was designed with CMR03F331JOYP and RoHS compliance is relevant to your repair or refurbishment process, verify whether CD5FY331JO3's non-compliant status affects your specific application requirements.
