Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Core Electrical Parameters (Non-Negotiable):

• Capacitance: 47 pF (exact match required)
• Voltage - Rated: 100V (exact match required)
• Temperature Coefficient: BP (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

Mechanical Parameters (Non-Negotiable):

• Package / Case: 0805 (2012 Metric) (exact match required)

Allowable Variations:

• Tolerance: ±10%, ±5%, or ±1% (tighter tolerances are acceptable upgrades)
• Manufacturer: Vishay Vitramon or KEMET (both qualified under MIL-PRF-55681)
• Packaging: Bulk or Tape & Reel (TR)
• RoHS Status: Compliant or non-compliant (application-dependent)

All identified substitute parts maintain identical capacitance, voltage rating, temperature coefficient, operating temperature range, and package specifications. Variations in tolerance and RoHS compliance are noted for design consideration.

Parameter Comparison

Engineering Selection Recommendations

CDR31BP470BJWSAJ (Vishay Vitramon, ±5% Tolerance) This substitute offers improved tolerance specification (±5% versus ±10%) while maintaining all core electrical and mechanical parameters. Manufactured by the same supplier under MIL-PRF-55681 standard. Note: RoHS non-compliant status requires verification against application requirements. Tape & Reel packaging supports automated assembly processes.

CDR31BP470BKUS7185 (KEMET, ±10% Tolerance) Direct equivalent with matching ±10% tolerance specification. Manufactured by KEMET under identical MIL-PRF-55681 military standard. RoHS non-compliant; REACH Affected status requires compliance verification for specific applications. Tape & Reel packaging available. Maintains identical electrical performance and reliability ratings.

CDR31BP470BFUS7185 (KEMET, ±1% Tolerance) Premium substitute with tightest tolerance specification (±1%) for applications requiring enhanced precision. All electrical and mechanical parameters remain equivalent. RoHS non-compliant; REACH Affected status applies. Tape & Reel packaging. Suitable for high-precision circuit designs where capacitance tolerance is critical.

All substitute parts maintain the military-grade MIL-PRF-55681 classification, S-level failure rate (0.001%), and -55°C to 125°C operating temperature range. Selection should account for RoHS compliance requirements, tolerance specifications, and packaging format needs.

Frequently Asked Questions (FAQ)

Q: Can CDR31BP470BJWSAJ replace CDR01BP470BKMSAT in all applications? A: Yes, provided RoHS non-compliance is acceptable for your application. The CDR31BP470BJWSAJ maintains identical electrical specifications (47 pF, 100V, BP coefficient, -55°C to 125°C) and mechanical package (0805). The ±5% tolerance is tighter than the original ±10%, making it functionally compatible.

Q: What is the difference between the three substitute parts? A: All three substitutes maintain identical capacitance (47 pF), voltage (100V), temperature coefficient (BP), and package (0805). Primary differences are: CDR31BP470BJWSAJ offers ±5% tolerance (Vishay Vitramon); CDR31BP470BKUS7185 offers ±10% tolerance (KEMET); CDR31BP470BFUS7185 offers ±1% tolerance (KEMET). All are RoHS non-compliant.

Q: Are there mechanical compatibility concerns with the substitute parts? A: Substitute parts have slightly smaller dimensions (0.079" L x 0.049" W versus 0.080" L x 0.050" W) and reduced thickness (0.051" versus 0.055" max). These variations remain within standard 0805 package tolerances and are mechanically compatible with PCB layouts designed for 0805 components.

Q: Does RoHS compliance status affect electrical performance? A: No. RoHS compliance status is a regulatory and material composition matter, not an electrical performance specification. All parts maintain identical electrical ratings and failure characteristics. RoHS status selection depends on application regulatory requirements and end-market destination.

Q: Which substitute should I select for precision-critical applications? A: CDR31BP470BFUS7185 with ±1% tolerance is appropriate for applications where capacitance precision is critical. The tighter tolerance reduces capacitance variation across the specified range, supporting designs with narrow tolerance budgets.

Q: Are all substitutes qualified under MIL-PRF-55681? A: Yes. All substitute parts are classified under the Military, MIL-PRF-55681 standard series (CDR31 base product number). All maintain S-level failure rate (0.001%) and high-reliability application classification.

Q: What packaging formats are available for substitutes? A: CDR01BP470BKMSAT is supplied in bulk packaging. All three substitutes are available in Tape & Reel (TR) format, supporting automated assembly and higher-volume production workflows.
