CDR31BP100BKMSAT Equivalent & Substitute Parts

Part Overview

The CDR31BP100BKMSAT is a 10 pF ±10% 100V ceramic capacitor in 0805 (2012 Metric) surface mount package, manufactured by Vishay Vitramon. This component is part of the military-grade CDR31 series compliant with MIL-PRF-55681 and is actively produced. The part is ROHS3 compliant with MSL 1 rating and a failure rate of S (0.001%), making it suitable for high-reliability applications. Alternative equivalent and substitute parts are available from KEMET to support supply chain flexibility and design requirements.

Substitute Part Grouping Explanation

Substitution of the CDR31BP100BKMSAT is determined by strict equivalence across the following critical parameters: capacitance value (10 pF), rated voltage (100V), temperature coefficient (BP), operating temperature range (-55°C ~ 125°C), package type (0805/2012 Metric), mounting method (Surface Mount MLCC), and failure rate classification (S). All substitute parts maintain these core electrical and mechanical specifications.

The substitute parts are categorized as follows:

Direct Manufacturer Equivalent (CDR01BP100BKUS7185): Identical electrical specifications and package dimensions from KEMET, manufactured to MIL-PRF-55681 standard with equivalent failure rate and MSL rating.

Upgrade Substitute (CDR31BP100BJUS): Tighter tolerance specification (±5% versus ±10%) while maintaining all other electrical and mechanical parameters, allowing for higher precision applications.

Parametric Equivalent (CDR31BP100BKUS7185): Identical specifications to the main part, including tolerance (±10%), from KEMET within the same CDR31 military series.

Parameter Comparison

Engineering Selection Recommendations

CDR31BP100BKMSAT (Primary Part): Select this part when ROHS3 compliance is a mandatory requirement. The Vishay Vitramon manufacturing source provides the specified compliance certification.

CDR31BP100BKUS7185 (Parametric Equivalent): This KEMET part provides identical electrical and mechanical specifications within the CDR31 military series. Use when supply from KEMET is preferred and RoHS3 compliance is not required. Dimensions and thickness match the primary part exactly.

CDR31BP100BJUS (Upgrade Substitute): Select this part when tighter tolerance (±5%) is required for precision circuit applications. All other specifications remain equivalent to the primary part. RoHS3 compliance is not available from this source.

CDR01BP100BKUS7185 (Direct Equivalent): This part provides equivalent electrical performance under MIL-PRF-55681 but uses the CDR01 military series designation. Dimensional variation exists (0.080" L x 0.050" W versus 0.079" L x 0.049" W, and 0.055" thickness versus 0.051"). Use only when dimensional tolerance permits the stated variations and RoHS3 compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can CDR31BP100BJUS replace CDR31BP100BKMSAT in all applications?

A: CDR31BP100BJUS is electrically and mechanically compatible with identical package dimensions and thickness. The tighter ±5% tolerance provides higher precision. However, RoHS3 compliance differs. Verify compliance requirements before substitution.

Q: What is the dimensional difference between CDR01BP100BKUS7185 and the primary part?

A: CDR01BP100BKUS7185 has slightly larger dimensions (0.080" L x 0.050" W versus 0.079" L x 0.049" W) and greater thickness (0.055" versus 0.051"). These variations may affect PCB layout and assembly clearances. Confirm board design tolerances before use.

Q: Are all substitute parts rated for the same operating temperature range?

A: Yes. All substitute parts operate across -55°C ~ 125°C with BP temperature coefficient, matching the primary part specification.

Q: What is the difference between CDR31 and CDR01 series designations?

A: Both series comply with MIL-PRF-55681 military standards and maintain equivalent failure rates (S, 0.001%). The series designation reflects different manufacturer product lines. Electrical and thermal performance are equivalent.

Q: Which substitute part should be selected for maximum supply availability?

A: CDR31BP100BKUS7185 has the highest inventory (1691 Pcs), followed by CDR31BP100BJUS (1380 Pcs) and CDR01BP100BKUS7185 (1281 Pcs).

Q: Is MSL rating identical across all parts?

A: Yes. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.
