Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR31BP101BFMSAT is determined by strict equivalence across the following parameters: capacitance value (100 pF), tolerance (±1%), voltage rating (100V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), package type (0805 / 2012 Metric), mounting method (Surface Mount MLCC), and military qualification (MIL-PRF-55681, CDR31 series). Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in circuit designs. Variations in packaging format (Tape & Reel versus other formats), RoHS compliance status, or inventory availability do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CDR31BP101BFUS (KEMET) is a parametric equivalent to the CDR31BP101BFMSAT (Vishay Vitramon). Both parts are active products qualified to MIL-PRF-55681 with identical electrical specifications and mechanical dimensions. Selection between these parts may be based on packaging format availability (Tape & Reel for the KEMET part) and compliance requirements. The Vishay Vitramon part carries RoHS3 compliance, while the KEMET part is RoHS non-compliant and REACH-affected. For applications requiring RoHS3 certification, the CDR31BP101BFMSAT is the appropriate choice. For applications without RoHS requirements, either part satisfies the electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can CDR31BP101BFUS be used as a direct replacement for CDR31BP101BFMSAT?

A: Yes. Both parts are parametric equivalents with identical capacitance (100 pF), tolerance (±1%), voltage rating (100V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), package dimensions (0805 / 2012 Metric), and military qualification (MIL-PRF-55681, CDR31 series). They are electrically and mechanically interchangeable.

Q: What is the difference between the two parts?

A: The primary differences are packaging format (CDR31BP101BFUS is supplied in Tape & Reel format) and compliance status (CDR31BP101BFMSAT is RoHS3 compliant; CDR31BP101BFUS is RoHS non-compliant and REACH-affected). Electrical and mechanical specifications are identical.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel versus other formats) affects only handling, storage, and assembly logistics. It does not alter electrical performance or mechanical fit in the circuit.

Q: Are both parts suitable for high-reliability applications?

A: Yes. Both parts are qualified to MIL-PRF-55681 with S-level failure rate (0.001%), MSL 1 (Unlimited moisture sensitivity), and are designated for high-reliability applications.

Q: Which part should be selected for RoHS-compliant designs?

A: The CDR31BP101BFMSAT (Vishay Vitramon) carries RoHS3 compliance certification. Select this part for designs requiring RoHS compliance.
