Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR31BX472BKMSAP is determined by strict equivalence across the following critical parameters:

• Capacitance value: 4700 pF
• Tolerance: ±10%
• Voltage rating: 100V
• Temperature coefficient: BX
• Operating temperature range: -55°C to 125°C
• Failure rate classification: S (0.001%)
• Package / Case: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCC
• Moisture sensitivity level: 1 (Unlimited)
• Military series compliance: MIL-PRF-55681, CDR31

The identified substitute parts maintain identical electrical and mechanical specifications. Differences in packaging format (bulk versus tape & reel) and RoHS compliance status do not affect functional interchangeability in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts are functionally equivalent and maintain active production status. Selection between them should be based on the following criteria:

CDR31BX472BKMSAP is the primary specification. It offers RoHS3 compliance and bulk packaging suitable for direct component selection in applications where RoHS compliance is required.

CDR31BX472BKWSAJ is a direct Vishay Vitramon equivalent available in tape & reel format. This part is suitable for high-volume manufacturing environments where automated tape & reel handling is standard. Note that this variant is RoHS non-compliant.

CDR31BX472BKUS is a KEMET-manufactured equivalent available in tape & reel format. This part maintains the same electrical and mechanical specifications and is suitable for applications where KEMET sourcing is preferred or required. This variant is also RoHS non-compliant and is subject to REACH regulations.

Selection should prioritize compliance requirements specific to the end application and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. All three parts share identical capacitance (4700 pF), tolerance (±10%), voltage rating (100V), temperature coefficient (BX), operating temperature range (-55°C to 125°C), and failure rate classification (S, 0.001%). They are electrically equivalent.

Q: What is the difference between bulk and tape & reel packaging? A: Bulk packaging (CDR31BX472BKMSAP) is suitable for manual assembly or small-volume production. Tape & reel packaging (CDR31BX472BKWSAJ and CDR31BX472BKUS) is designed for automated pick-and-place assembly systems and high-volume manufacturing. Both formats contain the same component.

Q: Does RoHS compliance affect component performance? A: No. RoHS compliance is a regulatory and material composition requirement, not a performance specification. The main part (CDR31BX472BKMSAP) is RoHS3 compliant, while the substitute parts are RoHS non-compliant. Selection depends on application regulatory requirements.

Q: Can I substitute a KEMET part for a Vishay Vitramon part? A: Yes, provided all electrical and mechanical parameters match. CDR31BX472BKUS (KEMET) is parametrically equivalent to CDR31BX472BKMSAP (Vishay Vitramon) and can be used as a direct substitute in applications where KEMET sourcing is acceptable.

Q: Are there any physical installation differences? A: No. All three parts use the same 0805 (2012 Metric) package with identical dimensions (2.00mm L x 1.25mm W x 1.30mm max thickness) and surface mount mounting type. PCB footprints and assembly processes are identical.

Q: What does MSL Level 1 mean? A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required.
