CDR32BP100BKWSAP Equivalent & Substitute Parts
Part Overview
The CDR32BP100BKWSAP is a 10 pF ceramic capacitor manufactured by Vishay Vitramon, rated for 100V operation with ±10% tolerance. This component belongs to the military-grade CDR32 series, compliant with MIL-PRF-55681, and is designed for high-reliability applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with 886 units in stock. Substitute parts are identified when they maintain identical electrical specifications, mechanical dimensions, and military qualification standards while potentially offering different packaging configurations or improved inventory availability.

Substitute Part Grouping Explanation
Substitution for the CDR32BP100BKWSAP is determined by strict equivalence across the following critical parameters:
- Electrical Specifications: Capacitance value (10 pF), tolerance (±10%), rated voltage (100V), and temperature coefficient (BP) must be identical
- Mechanical Compatibility: Package type (1206/3216 Metric), physical dimensions (0.126" L x 0.063" W, 1.30mm max thickness), and surface mount configuration must match
- Military Qualification: Series designation (CDR32), MIL-PRF-55681 compliance, and failure rate classification (S, 0.001%) must be maintained
- Environmental Performance: Operating temperature range (-55°C ~ 125°C) and moisture sensitivity level (MSL 1) must be equivalent
The identified substitute CDR32BP100BKWSAT differs only in packaging configuration (Cut Tape versus bulk packaging), maintaining all electrical, mechanical, and military specifications.

Engineering Selection Recommendations
Both CDR32BP100BKWSAP and CDR32BP100BKWSAT are active production components manufactured by Vishay Vitramon with identical military-grade specifications. Selection between these parts should be based on:
- Packaging Requirements: The main part (BKWSAP) is supplied in bulk packaging, while the substitute (BKWSAT) is supplied in Cut Tape configuration. Choose based on assembly line requirements and handling procedures.
- Inventory Availability: The substitute part (CDR32BP100BKWSAT) has higher current inventory (1212 units versus 886 units), which may be relevant for procurement lead time considerations.
- Compliance Status: Both parts maintain identical RoHS non-compliance status, ECCN classification (EAR99), and HTSUS code (8532.24.0020).
No electrical or mechanical redesign is required when substituting between these parts.
Frequently Asked Questions (FAQ)
Q: Can CDR32BP100BKWSAT be used as a direct replacement for CDR32BP100BKWSAP?
A: Yes. Both parts are electrically and mechanically identical, with the only difference being packaging configuration (Cut Tape versus bulk). They are interchangeable in circuit design and PCB assembly.
Q: What does the packaging designation mean?
A: The suffix "SAP" indicates bulk packaging, while "SAT" indicates Cut Tape packaging. Both contain the same component; the difference is in how units are supplied and handled during assembly.
Q: Are there any temperature or voltage derating considerations between these parts?
A: No. Both parts operate identically across the -55°C to 125°C range at 100V rated voltage with BP temperature coefficient characteristics.
Q: Do both parts meet the same military standards?
A: Yes. Both are qualified to MIL-PRF-55681 with identical failure rate classification (S, 0.001%) and are part of the same CDR32 military series.
Q: What is the significance of MSL 1 (Unlimited)?
A: MSL 1 indicates unlimited shelf life without moisture baking requirements, meaning these components can be stored indefinitely without special humidity control or pre-assembly baking procedures.
Q: Are there any RoHS compliance differences?
A: No. Both parts carry identical RoHS non-compliant status and share the same ECCN and HTSUS classifications.
