• Operating Temperature Range: -55°C to 125°C (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Military Standard Compliance: MIL-PRF-55681 (exact match required)

The substitute part CDR34BP103AFUS7185 meets all electrical and mechanical parameters specified above, confirming direct substitutability in applications requiring the CDR34BP103AFYSAT.

Parameter Comparison

Engineering Selection Recommendations

Both the CDR34BP103AFYSAT and CDR34BP103AFUS7185 are electrically and mechanically equivalent components meeting MIL-PRF-55681 military specifications. Selection between these parts should be based on the following factors:

RoHS Compliance: The CDR34BP103AFYSAT is ROHS3 compliant, while the CDR34BP103AFUS7185 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the Vishay Vitramon part.

REACH Status: The CDR34BP103AFUS7185 is marked as REACH Affected. Applications in REACH-regulated markets require verification of compliance status prior to selection.

Packaging Format: The CDR34BP103AFYSAT is supplied in bulk packaging, while the CDR34BP103AFUS7185 is supplied in Tape & Reel format. Selection depends on assembly process requirements and handling procedures.

Inventory Availability: The CDR34BP103AFUS7185 offers higher stock availability (1261 units) compared to the CDR34BP103AFYSAT (715 units), which may influence lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can CDR34BP103AFUS7185 be used as a direct replacement for CDR34BP103AFYSAT?

A: Yes, the CDR34BP103AFUS7185 is electrically and mechanically equivalent. Both parts share identical capacitance (10000 pF), tolerance (±1%), voltage rating (50V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), package type (1812/4532 Metric), and MIL-PRF-55681 compliance. Substitution is valid from an electrical standpoint.

Q: What are the compliance differences between these parts?

A: The CDR34BP103AFYSAT is ROHS3 compliant, while the CDR34BP103AFUS7185 is RoHS non-compliant and REACH Affected. Applications requiring RoHS compliance must use the Vishay Vitramon part. Applications in REACH-regulated regions require verification of the KEMET part's REACH status.

Q: Are there packaging differences?

A: Yes. The CDR34BP103AFYSAT is supplied in bulk packaging, while the CDR34BP103AFUS7185 is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes, while bulk packaging may require manual handling or custom reeling.

Q: Do both parts have the same failure rate?

A: Yes, both parts are rated at failure rate S (0.001%), meeting military-grade reliability standards for high-reliability applications.

Q: Which part should I select for new designs?

A: Selection depends on regulatory and supply chain requirements. For RoHS-compliant applications, use CDR34BP103AFYSAT. For applications where RoHS compliance is not required and higher inventory availability is prioritized, CDR34BP103AFUS7185 is suitable. Verify REACH compliance requirements for your specific market before final selection.
