CDR32BX472BKWSAP Equivalent & Substitute Parts

Part Overview

The CDR32BX472BKWSAP is a 4700 pF ceramic capacitor rated at 100V with BX temperature coefficient, manufactured by Vishay Vitramon. This component is part of the military-grade CDR32 series compliant with MIL-PRF-55681 specifications. The part is currently active in production and widely used in high-reliability applications requiring stable capacitance across extended temperature ranges (-55°C to 125°C). Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of the CDR32BX472BKWSAP is permissible when the replacement component maintains identical electrical specifications and mechanical compatibility. The critical parameters governing substitution are:

• Capacitance value: 4700 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 100V (exact match required)
• Temperature coefficient: BX (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Series compliance: MIL-PRF-55681 (exact match required)

The CDR32BX472BKUS7185, manufactured by KEMET, meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CDR32BX472BKWSAP and CDR32BX472BKUS7185 are active production components with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (the KEMET variant is supplied in Tape & Reel format)
• Supply chain and procurement logistics
• Compliance documentation requirements for specific applications

Both components are RoHS non-compliant and suitable for military and high-reliability applications requiring MIL-PRF-55681 certification.

Frequently Asked Questions (FAQ)

Q: Can CDR32BX472BKUS7185 be used as a direct replacement for CDR32BX472BKWSAP?

A: Yes. Both components share identical electrical parameters (4700 pF, ±10%, 100V, BX temperature coefficient), identical mechanical dimensions (1206 package, 3.20mm x 1.60mm x 1.30mm), and identical military compliance (MIL-PRF-55681). Direct substitution is permissible without circuit redesign.

Q: What is the difference between these two parts?

A: The primary difference is the manufacturer (Vishay Vitramon vs. KEMET) and packaging format. The KEMET part is supplied in Tape & Reel format, while the Vishay part uses standard packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS non-compliant, carry the same ECCN (EAR99) and HTSUS codes, and comply with MIL-PRF-55681. The KEMET variant includes REACH Affected status, which may be relevant for specific regulatory requirements.

Q: Can I substitute these parts in military applications?

A: Yes. Both components meet MIL-PRF-55681 specifications and carry identical failure rates (S, 0.001%), making them suitable for military and high-reliability applications.

Q: What is the significance of the BX temperature coefficient?

A: The BX temperature coefficient indicates a specific capacitance change rate across the operating temperature range (-55°C to 125°C). Both parts maintain this specification identically, ensuring predictable circuit behavior across temperature extremes.
