CDR32BX472BKMSAP Equivalent & Substitute Parts

Part Overview

The CDR32BX472BKMSAP is a 4700 pF ceramic capacitor rated at 100V with BX temperature coefficient, manufactured by Vishay Vitramon under the military-grade CDR32 series compliant with MIL-PRF-55681. This surface-mount multilayer ceramic capacitor (MLCC) in 1206 package format is designed for high-reliability applications requiring stable performance across -55°C to 125°C operating temperature range with a failure rate of S (0.001%). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR32BX472BKMSAP is determined by strict equivalence across the following parameters: capacitance value (4700 pF), tolerance (±10%), voltage rating (100V), temperature coefficient (BX), operating temperature range (-55°C to 125°C), package format (1206/3216 Metric), mounting type (Surface Mount MLCC), and military series compliance (MIL-PRF-55681, CDR32). All identified substitutes maintain identical electrical and mechanical specifications within these defined parameters. Substitution does not extend to compliance certifications, inventory status, or packaging format variations beyond those explicitly listed.

Parameter Comparison

Engineering Selection Recommendations

The CDR32BX472BKUS7185 manufactured by KEMET is electrically and mechanically equivalent to the CDR32BX472BKMSAP. Both parts maintain identical capacitance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and military-grade MIL-PRF-55681 compliance. Selection between these parts should be based on product status (both Active), inventory availability, and compliance requirements specific to the application. The CDR32BX472BKMSAP carries RoHS3 compliance, while the CDR32BX472BKUS7185 is RoHS non-compliant and REACH Affected. Application requirements for environmental compliance and regulatory certifications must be evaluated prior to part selection.

Frequently Asked Questions (FAQ)

Q: Can CDR32BX472BKUS7185 be used as a direct replacement for CDR32BX472BKMSAP?

A: Yes, the CDR32BX472BKUS7185 is electrically and mechanically equivalent. Both parts share identical capacitance (4700 pF), voltage rating (100V), temperature coefficient (BX), operating temperature range (-55°C to 125°C), package format (1206/3216 Metric), and military series compliance (MIL-PRF-55681, CDR32). Substitution is valid from a functional and dimensional standpoint.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Vishay Vitramon vs. KEMET), RoHS compliance status (RoHS3 Compliant vs. RoHS non-compliant), REACH status (not listed vs. REACH Affected), and packaging format (standard vs. Tape & Reel). Electrical and mechanical specifications are identical.

Q: Are there any compliance considerations when substituting these parts?

A: Yes. The CDR32BX472BKMSAP is RoHS3 compliant, while the CDR32BX472BKUS7185 is RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH regulations must use the CDR32BX472BKMSAP or verify that the substitute meets applicable compliance requirements.

Q: Will the 1206 package dimensions remain the same with the substitute part?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.051" (1.30mm). PCB layout and assembly processes remain unchanged.

Q: What is the failure rate for both parts?

A: Both the CDR32BX472BKMSAP and CDR32BX472BKUS7185 maintain a failure rate of S (0.001%), consistent with military-grade MIL-PRF-55681 specifications for high-reliability applications.
