Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR01BP150BKWSAJ is determined by the following critical parameters:

• Capacitance Value: Must be 15 pF
• Rated Voltage: Must be 100V or higher
• Temperature Coefficient: Must be BP
• Operating Temperature Range: Must support -55°C ~ 125°C
• Package / Case: Must be 0805 (2012 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Military Standard Compliance: Must comply with MIL-PRF-55681
• Failure Rate Classification: Must maintain S (0.001%) or better

The substitute part CDR31BP150BJUS7185 meets all these criteria. While it features a tighter tolerance specification (±5% versus ±10%), this represents an improvement in precision and does not restrict substitution. Both parts share identical capacitance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and military standard compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the CDR01BP150BKWSAJ and CDR31BP150BJUS7185 maintain active product status and comply with MIL-PRF-55681 military specifications. The substitute part CDR31BP150BJUS7185 offers improved tolerance performance (±5% versus ±10%), which provides tighter capacitance accuracy without compromising compatibility. Both parts share identical electrical ratings, temperature performance, and failure rate classifications. Physical dimensions are within acceptable tolerances for 0805 package footprints, with the substitute part featuring slightly reduced thickness (1.30mm versus 1.40mm maximum). Both parts carry MSL 1 rating and are RoHS non-compliant, maintaining equivalent environmental handling requirements. Selection between these parts may be based on availability, packaging format preference (Tape & Reel for the substitute), or tolerance requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can CDR31BP150BJUS7185 be used as a direct replacement for CDR01BP150BKWSAJ?

A: Yes. Both parts share identical capacitance (15 pF), voltage rating (100V), temperature coefficient (BP), operating temperature range (-55°C ~ 125°C), package type (0805 / 2012 Metric), and military standard compliance (MIL-PRF-55681). The substitute features improved tolerance (±5% versus ±10%), which does not restrict substitution.

Q: Are there physical compatibility concerns between these parts?

A: No. Both parts are surface mount MLCCs in the 0805 (2012 Metric) package. Dimensional differences are minimal: the substitute is 0.001" shorter in length and 0.001" shorter in width, with 0.004" reduced maximum thickness. These variations fall within standard PCB footprint tolerances for 0805 components.

Q: Do both parts meet the same military specifications?

A: Yes. Both parts comply with MIL-PRF-55681 and maintain the same S (0.001%) failure rate classification. The main part is designated CDR01 series while the substitute is CDR31 series, but both meet the same military standard requirements.

Q: What is the difference in tolerance between these parts?

A: The main part CDR01BP150BKWSAJ has ±10% tolerance, while the substitute CDR31BP150BJUS7185 has ±5% tolerance. The tighter tolerance of the substitute represents improved precision and does not prevent substitution.

Q: Are moisture sensitivity requirements the same?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and equivalent handling requirements.

Q: What packaging formats are available?

A: The main part is available in standard packaging, while the substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.
