CDR01BX102BKMSAC Equivalent & Substitute Parts

Part Overview

The CDR01BX102BKMSAC is a 1000 pF ±10% 100V ceramic capacitor in 0805 (2012 Metric) surface mount package, manufactured by Vishay Vitramon. This military-grade MLCC (Multilayer Ceramic Capacitor) operates across -55°C to 125°C with BX temperature coefficient and meets MIL-PRF-55681 specifications. The part is active and in production with 737 units currently in stock. Equivalent and substitute parts are identified for applications requiring alternative sourcing, packaging formats, or manufacturer options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance (1000 pF), tolerance (±10%), voltage rating (100V), temperature coefficient (BX), operating temperature range (-55°C to 125°C), package type (0805 / 2012 Metric), mounting method (Surface Mount MLCC), failure rate (S / 0.001%), military series compliance (MIL-PRF-55681), and moisture sensitivity level (1 / Unlimited).

Substitute parts are grouped into two categories:

Direct Manufacturer Substitutes: Parts from alternative manufacturers (Vishay Vitramon CDR31 series, KYOCERA AVX CDR31 series) that maintain identical electrical specifications and package dimensions within tolerance. These differ primarily in packaging format (Cut Tape vs. Tape & Reel) and RoHS compliance status.

Parametric Equivalents: Parts from KEMET (CDR01 series) that match all electrical parameters and maintain the same physical footprint and thickness specifications, differing only in packaging configuration and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

CDR01BX102BKUS7370 (KEMET): Highest inventory availability (2964 units) with identical physical dimensions and thickness to the primary part. Maintains CDR01 base product number lineage. Suitable for applications where RoHS3 compliance is not required and Tape & Reel packaging is acceptable.

CDR01BX102BKUS7185 (KEMET): Identical physical specifications to CDR01BX102BKMSAC with 1061 units in stock. Provides alternative sourcing from KEMET while preserving exact footprint compatibility. Appropriate for high-reliability applications requiring military-grade performance.

CDR31BX102BKUS (KYOCERA AVX): 938 units available in Tape & Reel format. Slightly reduced physical dimensions (2.00 x 1.25 mm vs. 2.03 x 1.27 mm) and thickness (1.30 mm vs. 1.40 mm) remain within 0805 package specification tolerance. Suitable for space-constrained designs.

CDR31BX102BKWSAT (Vishay Vitramon): 901 units in Cut Tape packaging. Same dimensional reduction as CDR31 series. Provides alternative packaging format from the original manufacturer.

All substitute parts maintain electrical equivalence across capacitance, tolerance, voltage rating, temperature coefficient, operating range, failure rate, and military series compliance.

Frequently Asked Questions (FAQ)

Q: Can CDR31BX102BKUS replace CDR01BX102BKMSAC in existing PCB designs?

A: Yes, electrically and functionally. The CDR31 series maintains identical electrical specifications (1000 pF, ±10%, 100V, BX coefficient, -55°C to 125°C). Physical dimensions are slightly smaller (2.00 x 1.25 mm vs. 2.03 x 1.27 mm) and thickness is reduced (1.30 mm vs. 1.40 mm), but both conform to 0805 (2012 Metric) package specifications. PCB footprints designed for 0805 will accommodate both variants.

Q: What is the difference between CDR01 and CDR31 base product numbers?

A: Both are military-grade MIL-PRF-55681 ceramic capacitors from Vishay Vitramon. The CDR31 series represents a different product line within the military portfolio. Electrical parameters are identical for the specified values. Selection between them depends on availability, packaging format, and compliance requirements.

Q: Are KEMET CDR01BX102BKUS7185 and CDR01BX102BKUS7370 interchangeable?

A: Yes. Both are KEMET-manufactured CDR01 series parts with identical electrical specifications and physical dimensions (2.03 x 1.27 mm, 1.40 mm thickness). The primary difference is inventory availability (1061 vs. 2964 units). Both are supplied in Tape & Reel packaging.

Q: Why does the primary part (CDR01BX102BKMSAC) show ROHS3 compliance while substitutes do not?

A: RoHS compliance status is determined by the specific manufacturing lot and certification date. The primary part carries ROHS3 certification; substitute parts from the same or alternative manufacturers may not have equivalent certifications depending on their production timeline and supply chain documentation. Verify compliance requirements for your specific application before selection.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 indicates unlimited shelf life without moisture exposure controls. All listed parts carry MSL 1 rating, meaning they do not require special desiccant packaging or baking procedures prior to assembly. This simplifies inventory management and reduces handling complexity.

Q: Can I use Cut Tape (CDR31BX102BKWSAT) instead of Tape & Reel packaging?

A: Yes, if your assembly process accommodates Cut Tape format. Cut Tape is suitable for lower-volume production or manual assembly. Tape & Reel format is standard for automated pick-and-place equipment. Verify your manufacturing equipment compatibility before ordering.
