CDR32BX472BKUSAP Equivalent & Substitute Parts

Part Overview

The CDR32BX472BKUSAP is a military-grade ceramic capacitor manufactured by Vishay Vitramon, rated at 4700 pF with 100V voltage rating and BX temperature coefficient. This component is designed for high-reliability applications requiring MIL-PRF-55681 compliance and operates across the temperature range of -55°C to 125°C. The part is currently active in production with 881 pieces available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or application-specific packaging needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR32BX472BKUSAP is determined by strict equivalence across the following critical parameters:

• Electrical Parameters: Capacitance value (4700 pF), tolerance (±10%), voltage rating (100V), and temperature coefficient (BX) must be identical
• Mechanical Parameters: Package designation (1206/3216 Metric), mounting type (Surface Mount, MLCC), and physical dimensions (0.126" L × 0.063" W, 3.20mm × 1.60mm) must match
• Reliability Standards: Military series designation (MIL-PRF-55681, CDR32), failure rate classification (S), and moisture sensitivity level (MSL 1) must be maintained
• Operating Conditions: Temperature range (-55°C to 125°C) must be supported

The identified substitute part CDR32BX472BKUS7185 meets all these criteria while differing only in manufacturer (KEMET vs. Vishay Vitramon) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both the CDR32BX472BKUSAP and CDR32BX472BKUS7185 are active production components meeting identical military specifications under MIL-PRF-55681. Selection between these parts should be based on:

• Inventory Availability: CDR32BX472BKUSAP has 881 pieces in stock; CDR32BX472BKUS7185 has 1764 pieces available
• Packaging Format: CDR32BX472BKUSAP uses standard packaging; CDR32BX472BKUS7185 is supplied in Tape & Reel format, which may affect procurement and assembly processes
• Manufacturer Qualification: Both manufacturers produce military-grade components to identical specifications; selection may depend on existing qualification documentation or supply chain agreements
• Compliance Status: Both parts are RoHS non-compliant and carry identical ECCN and HTSUS classifications

Frequently Asked Questions (FAQ)

Q: Can CDR32BX472BKUS7185 be used as a direct replacement for CDR32BX472BKUSAP?

A: Yes. Both parts are electrically and mechanically equivalent, meeting identical MIL-PRF-55681 specifications with matching capacitance (4700 pF), voltage rating (100V), temperature coefficient (BX), operating temperature range (-55°C to 125°C), package type (1206/3216 Metric), and failure rate classification (S). The primary difference is the manufacturer and packaging format.

Q: What is the significance of the packaging difference between these parts?

A: CDR32BX472BKUSAP is supplied in standard packaging, while CDR32BX472BKUS7185 is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly processes but does not impact electrical or mechanical performance. Tape & Reel packaging is typically used for high-volume production runs.

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

A: No. Both parts carry identical certifications: MIL-PRF-55681 military series designation, EAR99 ECCN classification, 8532.24.0020 HTSUS code, MSL 1 moisture sensitivity level, and RoHS non-compliant status.

Q: What parameters must remain constant when selecting a substitute for the CDR32BX472BKUSAP?

A: Capacitance (4700 pF), tolerance (±10%), voltage rating (100V), temperature coefficient (BX), operating temperature range (-55°C to 125°C), package type (1206/3216 Metric), mounting type (Surface Mount, MLCC), and military series designation (MIL-PRF-55681, CDR32) must all remain identical.

Q: Can parts with different temperature coefficients be substituted?

A: No. The temperature coefficient (BX) is a critical electrical parameter that determines capacitance stability across the operating temperature range. Substitution is only valid with parts carrying the identical BX designation.
