Engineering Selection Recommendations

Both CDR35BX474AKWSAJ and CDR35BX474AKUS are active products with identical electrical specifications, mechanical dimensions, and military qualification status under MIL-PRF-55681. Selection between these parts is determined by manufacturer availability, inventory levels, and supply chain requirements rather than technical performance differences. The CDR35BX474AKUS carries REACH Affected status, which may be relevant for applications subject to European regulatory compliance. Both parts maintain RoHS non-compliant status, consistent with military-grade ceramic capacitor specifications. Inventory availability shows 1078 units for the Vishay Vitramon variant and 1111 units for the KYOCERA AVX variant.

Frequently Asked Questions (FAQ)

Q: Can CDR35BX474AKUS be used as a direct replacement for CDR35BX474AKWSAJ?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including capacitance, voltage rating, temperature coefficient, operating temperature range, failure rate classification, package dimensions, and moisture sensitivity level. They are interchangeable in applications requiring MIL-PRF-55681 compliance.

Q: Are there differences in military specification compliance between these parts?

A: No. Both parts conform to the same military specification series (MIL-PRF-55681, CDR35) and maintain identical failure rate classifications of S (0.001%).

Q: What is the significance of the REACH Affected status on the KYOCERA AVX part?

A: REACH Affected status indicates the part may contain substances of concern under European Union regulations. This designation is provided for regulatory tracking purposes and does not affect electrical or mechanical performance. Applications subject to REACH compliance requirements should account for this status during component selection.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both CDR35BX474AKWSAJ and CDR35BX474AKUS are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the physical dimensions identical for PCB layout purposes?

A: Yes. Both parts share identical dimensions of 0.177" L x 0.252" W (4.50mm x 6.40mm) with maximum thickness of 0.059" (1.50mm), ensuring identical footprint compatibility in 1825 (4564 Metric) package format.
