Engineering Selection Recommendations

All three parts—CMR05F331JPDP, CMR05F331JPDM, and CMR05F331JPDR—are parametric equivalents with identical electrical and mechanical specifications. Selection among these parts is based on availability and inventory status rather than technical performance differences.

CMR05F331JPDP (Primary Part): 1100 pieces in stock. Active product status with full ROHS3 compliance and REACH unaffected designation.

CMR05F331JPDM (Substitute): 646 pieces in stock. Active product status with identical compliance certifications and electrical characteristics.

CMR05F331JPDR (Substitute): 857 pieces in stock. Active product status with identical compliance certifications and electrical characteristics.

All parts are suitable for applications requiring 330 pF capacitance at 500 V with ±5% tolerance across the -55°C to 150°C operating range. Direct substitution is supported without circuit redesign or performance impact.

Frequently Asked Questions (FAQ)

Q: Can CMR05F331JPDM and CMR05F331JPDR be used interchangeably with CMR05F331JPDP?

A: Yes. All three parts are parametric equivalents with identical capacitance (330 pF), voltage rating (500 V), tolerance (±5%), dielectric material (mica), operating temperature range (-55°C to 150°C), and physical dimensions. Direct substitution is supported without circuit modification.

Q: Are there any differences in the radial package configuration between these parts?

A: No. All three parts share identical radial package specifications: 0.224" (5.70mm) lead spacing, 0.469" L x 0.209" W (11.90mm x 5.30mm) dimensions, and 0.390" (9.90mm) maximum seated height. PCB layout compatibility is maintained across all substitutes.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. CMR05F331JPDP, CMR05F331JPDM, and CMR05F331JPDR are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) and REACH unaffected status. Regulatory requirements are identical across all three parts.

Q: What is the basis for substitution between these CMR series mica capacitors?

A: Substitution is based on complete equivalence across electrical parameters (capacitance, voltage, tolerance, dielectric), mechanical parameters (mounting type, package, dimensions, lead spacing), and environmental specifications (temperature range, compliance certifications). All three parts meet these criteria without exception.

Q: Are there inventory considerations when selecting between these parts?

A: Inventory availability differs: CMR05F331JPDP (1100 pcs), CMR05F331JPDR (857 pcs), and CMR05F331JPDM (646 pcs). Selection may be influenced by supply requirements, but technical performance and compatibility remain identical.
