CDR35BX104BKWSAT Equivalent & Substitute Parts

Part Overview

The CDR35BX104BKWSAT is a 0.1 µF ±10% 100V ceramic capacitor manufactured by Vishay Vitramon, qualified to MIL-PRF-55681 military specifications. This surface mount multilayer ceramic capacitor (MLCC) in 1825 (4564 Metric) package is designed for high-reliability applications requiring stable performance across -55°C to 125°C operating temperature range with a failure rate of S (0.001%). Finding equivalent and substitute parts is necessary to ensure supply chain continuity, optimize inventory management, and maintain design flexibility across multiple qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the CDR35BX104BKWSAT is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF
• Tolerance: ±10%
• Rated voltage: 100V
• Temperature coefficient: BX
• Operating temperature range: -55°C ~ 125°C
• Failure rate classification: S (0.001%)
• Package designation: 1825 (4564 Metric)
• Mounting type: Surface Mount, MLCC
• Military qualification: MIL-PRF-55681

All substitute parts listed below meet these electrical and mechanical requirements. Variations in physical dimensions (length, width, thickness) within the 1825 package specification and differences in packaging format (Tape & Reel vs. Bulk) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—CDR35BX104BKWSAT (Vishay Vitramon), CDR05BX104BKUS (KEMET), and CDR35BX104BKUS (KYOCERA AVX)—are active products with identical electrical specifications and military qualification to MIL-PRF-55681. Selection between these parts may be based on:

• Packaging format availability: CDR05BX104BKUS is supplied in Tape & Reel format; CDR35BX104BKUS is supplied in Bulk format; CDR35BX104BKWSAT packaging format is not specified in the provided data.
• Inventory availability and lead times from respective manufacturers.
• Existing qualification and procurement agreements within your organization.
• Physical dimension tolerances within the 1825 package specification, which may affect PCB layout constraints in space-critical applications.

All parts share identical RoHS non-compliance status, MSL rating of 1 (Unlimited), ECCN classification (EAR99), and HTSUS code (8532.24.0020).

Frequently Asked Questions (FAQ)

Q: Can CDR05BX104BKUS replace CDR35BX104BKWSAT in my design?

A: Yes. Both parts meet identical electrical specifications (0.1 µF, ±10%, 100V, BX temperature coefficient, -55°C to 125°C operating range, S failure rate) and are qualified to MIL-PRF-55681. The primary difference is packaging format (Tape & Reel vs. unspecified) and minor physical dimension variations within the 1825 package specification.

Q: What is the difference between CDR35 and CDR05 base product numbers?

A: CDR35 and CDR05 are different military-qualified series designations from different manufacturers (Vishay Vitramon and KEMET respectively). Both series meet MIL-PRF-55681 requirements. The base product number does not affect electrical performance or substitutability when all other parameters are identical.

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

A: All three parts share identical compliance status: RoHS non-compliant, MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8532.24.0020. KEMET's CDR05BX104BKUS carries additional REACH Affected status, and KYOCERA AVX's CDR35BX104BKUS also carries REACH Affected status. These designations do not affect functional substitutability.

Q: Do physical dimension differences matter for substitution?

A: Physical dimensions vary slightly within the 1825 (4564 Metric) package specification. CDR35BX104BKWSAT and CDR35BX104BKUS measure 0.177" L x 0.252" W x 0.059" thick; CDR05BX104BKUS measures 0.180" L x 0.250" W x 0.080" thick. These variations are within standard package tolerances and do not affect electrical performance. Verify PCB layout constraints if space is critical.

Q: What inventory levels are available?

A: CDR35BX104BKWSAT: 869 Pcs; CDR05BX104BKUS: 1134 Pcs; CDR35BX104BKUS: 806 Pcs. All parts are listed as new original stock.
