Substitute Part Grouping Explanation

Substitution of the CDR32BX472BKWRAP is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitution:

• 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 ~ 125°C (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Physical dimensions: 0.126" L x 0.063" W, 0.051" max thickness (exact match required)
• Series compliance: MIL-PRF-55681, CDR32 (exact match required)
• Failure rate: R (0.01%) (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

Substitute parts identified within this specification maintain identical electrical performance and mechanical compatibility. Differences are limited to packaging format and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both CDR32BX472BKWRAP and CDR32BX472BKURAJ are active production components manufactured by Vishay Vitramon with identical electrical specifications and mechanical dimensions. Selection between these parts is determined by packaging and procurement requirements:

• CDR32BX472BKWRAP is supplied in bulk packaging format, suitable for applications requiring individual component handling or smaller quantity orders.
• CDR32BX472BKURAJ is supplied in Tape & Reel (TR) format, optimized for automated assembly processes and high-volume production environments.

Both parts comply with MIL-PRF-55681 military specifications and maintain RoHS non-compliant status. Component selection should be based on assembly methodology and supply chain logistics rather than electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can CDR32BX472BKURAJ be used as a direct replacement for CDR32BX472BKWRAP?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: CDR32BX472BKWRAP is bulk packaged, while CDR32BX472BKURAJ is supplied in Tape & Reel format. Direct substitution is valid for any application where the assembly process can accommodate the alternative packaging.

Q: What does the BX temperature coefficient indicate?

A: BX temperature coefficient specifies the capacitance change characteristics across the operating temperature range of -55°C to 125°C. This designation is part of the military specification MIL-PRF-55681 and ensures predictable performance in high-reliability applications.

Q: Are there any compliance differences between these parts?

A: No. Both parts share identical compliance profiles: MIL-PRF-55681 military specification compliance, R (0.01%) failure rate, MSL 1 (Unlimited) moisture sensitivity level, and RoHS non-compliant status.

Q: Which packaging format should be selected for automated assembly?

A: CDR32BX472BKURAJ in Tape & Reel (TR) format is designed for automated pick-and-place assembly processes. CDR32BX472BKWRAP bulk packaging is suitable for manual assembly or lower-volume production runs.

Q: Is the 1206 package size compatible with standard PCB designs?

A: Yes. The 1206 (3216 Metric) package is a standard surface-mount component size with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.051" (1.30mm). This package is compatible with conventional PCB design standards and automated assembly equipment.
