Key Parameters

Substitute Part Grouping Explanation

The CD5FA151JO3F qualifies as a parametric equivalent to the CMR03F151JOAR based on matching critical electrical and mechanical specifications. Both components maintain identical capacitance values (150 pF), voltage ratings (100 V), tolerance specifications (±5%), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting configuration (through-hole radial), and physical dimensions including lead spacing (0.118" / 3.00 mm) and maximum seated height (0.228" / 5.80 mm). Both devices are manufactured by Cornell Dubilier Electronics and possess ROHS3 compliance and MSL 1 classification. The substitution relationship is based exclusively on these allowed parameters without consideration of manufacturing series differences.

Parameter Comparison

Engineering Selection Recommendations

Selection between CMR03F151JOAR and CD5FA151JO3F is determined by product availability and manufacturing series requirements. Both components maintain Active product status and identical ROHS3 compliance and REACH unaffected designations, ensuring equivalence for regulatory and supply chain purposes. The CD5FA151JO3F demonstrates higher inventory availability (1541 pcs vs 957 pcs), which may influence procurement decisions based on lead time and stock position requirements.

Frequently Asked Questions (FAQ)

Can CD5FA151JO3F be used as a direct replacement for CMR03F151JOAR?

Yes. Both components are 150 pF mica capacitors with 100 V ratings, ±5% tolerance, identical physical dimensions, and matching thermal performance. The radial through-hole package configuration and lead spacing are identical, permitting direct PCB substitution without layout modifications.

Are there differences in dielectric performance between these parts?

No. Both components utilize mica as the dielectric material and operate across the same temperature range (-55°C to 125°C). The identical tolerance specification (±5%) ensures equivalent capacitance stability.

What is the significance of different manufacturing series designations?

The CMR and CD5 series designations indicate different product lines within Cornell Dubilier Electronics. Series differences do not affect the electrical or mechanical parameters relevant to substitution, which are explicitly matched across all critical specifications.

Are both components suitable for high-reliability applications?

Both components are ROHS3 compliant with MSL 1 classification, indicating unlimited moisture sensitivity protection. Both are classified as Active with regulatory compliance across REACH and ECCN requirements.

Do these components require any modifications to existing PCB designs?

No. The identical physical dimensions, lead spacing (0.118" / 3.00 mm), and maximum seated height (0.228" / 5.80 mm) ensure compatibility with existing PCB footprints and design specifications without modification.
