Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDR34BP472BJWSAT is permissible when the replacement component maintains the following critical parameters:

• Capacitance value of 4700 pF
• Voltage rating of 100V or higher
• Temperature coefficient BP
• Operating temperature range of -55°C to 125°C or wider
• Package / Case designation 1812 (4532 Metric)
• Surface Mount, MLCC mounting type
• Compliance with MIL-PRF-55681 military standard
• Failure rate classification S (0.001%) or better
• Moisture Sensitivity Level 1

The CDR34BP472BFUS7185 qualifies as a direct substitute based on these parameters. Tolerance variation (±5% to ±1%) represents an upgrade in precision capability and does not preclude substitution, as tighter tolerance is compatible with applications requiring the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the CDR34BP472BJWSAT and CDR34BP472BFUS7185 maintain active product status and full compliance with MIL-PRF-55681 military specifications. The primary distinction is tolerance specification: the KEMET substitute offers ±1% tolerance compared to the Vishay Vitramon original at ±5%. This represents improved precision capability and is electrically compatible with applications designed for the original component.

Selection between these parts should be based on procurement availability, packaging requirements (bulk versus Tape & Reel), and specific tolerance requirements of the application. Both components are RoHS non-compliant and classified under ECCN EAR99 with identical HTSUS coding (8532.24.0020).

Frequently Asked Questions (FAQ)

Q: Can the CDR34BP472BFUS7185 be used as a direct replacement for the CDR34BP472BJWSAT?

A: Yes. Both components share identical capacitance (4700 pF), voltage rating (100V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), package designation (1812 / 4532 Metric), and military standard compliance (MIL-PRF-55681). The substitute features tighter tolerance (±1% versus ±5%), which is compatible with the original specification.

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

A: The CDR34BP472BFUS7185 provides ±1% tolerance compared to ±5% for the CDR34BP472BJWSAT. Tighter tolerance indicates greater precision in capacitance value. Applications designed for ±5% tolerance can accept ±1% components without functional impact.

Q: Are there packaging differences between these parts?

A: Yes. The CDR34BP472BJWSAT is supplied in bulk packaging, while the CDR34BP472BFUS7185 is supplied in Tape & Reel (TR) format. Both use identical 1812 (4532 Metric) package dimensions and surface mount configuration. Packaging selection depends on assembly process requirements and volume considerations.

Q: Do both parts meet military specifications?

A: Both components comply with MIL-PRF-55681 military standard, maintain S-class failure rate (0.001%), and are rated for -55°C to 125°C operating temperature. Both are classified as Moisture Sensitivity Level 1 (Unlimited).

Q: What is the physical size of these components?

A: Both parts measure 0.177" L × 0.126" W (4.50mm × 3.20mm) with maximum thickness of 0.059" (1.50mm). The 1812 (4532 Metric) package designation is identical for both components.
