CDR02BX472BKUSAT Equivalent & Substitute Parts

Part Overview

The CDR02BX472BKUSAT 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 CDR02 series compliant with MIL-PRF-55681 and is designed for high-reliability applications. The part maintains active product status with proven field performance characterized by an S-level failure rate (0.001%). Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, procurement lead times, or design flexibility needs while maintaining compliance with military specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CDR02BX472BKUSAT 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
• Failure rate classification: S (0.001%)
• Package / Case: 1805 (4512 Metric)
• Mounting type: Surface Mount, MLCC
• Military series compliance: MIL-PRF-55681, CDR02

The identified substitute part CDR02BX472BKUS7185 meets all electrical and mechanical parameters required for direct substitution. Differences in manufacturer (KEMET vs. Vishay Vitramon) and packaging format (Tape & Reel vs. standard packaging) do not affect functional equivalence when these parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Both the CDR02BX472BKUSAT and CDR02BX472BKUS7185 maintain active product status and comply with MIL-PRF-55681 military specifications. Selection between these parts should be based on:

• Procurement availability and lead time requirements
• Packaging format compatibility with assembly processes (standard vs. Tape & Reel)
• Inventory levels and cost considerations
• Existing qualification history with either manufacturer in the application

Both parts are RoHS non-compliant and classified under ECCN EAR99 with identical HTSUS codes (8532.24.0020), indicating equivalent regulatory treatment. The MSL rating of 1 (Unlimited) applies to both parts, eliminating moisture sensitivity as a differentiation factor.

Frequently Asked Questions (FAQ)

Q: Can CDR02BX472BKUS7185 be used as a direct replacement for CDR02BX472BKUSAT?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters including capacitance, voltage rating, temperature coefficient, operating temperature range, failure rate, and package dimensions. The difference in manufacturer does not affect functional compatibility when all electrical and mechanical parameters are identical.

Q: What is the significance of the packaging format difference (standard vs. Tape & Reel)?

A: Tape & Reel (TR) packaging is a continuous strip format optimized for automated assembly processes, while standard packaging may refer to alternative formats. The selection depends on your assembly equipment and process requirements. Both formats contain the same component with identical electrical performance.

Q: Are there any compliance or certification differences between these parts?

A: Both parts comply with MIL-PRF-55681 military specifications and carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications. Both are RoHS non-compliant and have MSL rating 1 (Unlimited). No compliance differentiation exists between the two parts.

Q: What parameters must remain constant for substitution eligibility?

A: Capacitance (4700 pF), tolerance (±10%), voltage rating (100V), temperature coefficient (BX), operating temperature range (-55°C to 125°C), failure rate (S, 0.001%), package type (1805/4512 Metric), and mounting type (Surface Mount, MLCC) must all match exactly for direct substitution.

Q: Can I substitute with a different capacitance value or voltage rating?

A: No. Substitution is limited to parts with identical electrical specifications. Different capacitance values or voltage ratings will not function equivalently in the circuit and are not considered substitutes.
