Substitute Part Grouping Explanation

Substitution eligibility for the CDR31BP470BJMSAP is determined by strict equivalence across the following critical parameters:

• Capacitance value: 47 pF
• Tolerance: ±5%
• Rated voltage: 100V
• Temperature coefficient: BP
• Operating temperature range: -55°C to 125°C
• Package / Case: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCC
• Military qualification: MIL-PRF-55681, CDR31 series
• Failure rate classification: S (0.001%)
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute part CDR31BP470BJWSAJ meets all electrical and mechanical parameters. The primary distinction between the main part and substitute is packaging format (bulk versus tape & reel) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both CDR31BP470BJMSAP and CDR31BP470BJWSAJ are active production parts from Vishay Vitramon with identical electrical specifications and military qualification. Selection between these parts should be based on:

Packaging Requirements: CDR31BP470BJMSAP is supplied in bulk packaging, while CDR31BP470BJWSAJ is supplied in tape & reel format. Choose based on assembly process requirements and inventory management practices.

Compliance Requirements: CDR31BP470BJMSAP carries ROHS3 compliance certification. CDR31BP470BJWSAJ is RoHS non-compliant. For applications subject to RoHS directives or customer specifications requiring RoHS compliance, CDR31BP470BJMSAP is the appropriate selection.

Inventory Availability: Current stock levels differ between variants. CDR31BP470BJMSAP has 886 pieces in stock; CDR31BP470BJWSAJ has 3720 pieces in stock. Procurement decisions may consider availability and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Are CDR31BP470BJMSAP and CDR31BP470BJWSAJ electrically identical?

A: Yes. Both parts have identical capacitance (47 pF), tolerance (±5%), rated voltage (100V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), and failure rate classification (S, 0.001%). They are functionally equivalent in circuit applications.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format and RoHS compliance status. CDR31BP470BJMSAP is supplied in bulk packaging and is ROHS3 compliant. CDR31BP470BJWSAJ is supplied in tape & reel format and is RoHS non-compliant.

Q: Can I use CDR31BP470BJWSAJ as a direct replacement for CDR31BP470BJMSAP?

A: Direct replacement is possible from an electrical and mechanical standpoint, as all performance parameters are identical. However, verify that your application or customer requirements do not mandate RoHS compliance, as CDR31BP470BJWSAJ does not meet this standard.

Q: Are both parts qualified to military standards?

A: Yes. Both CDR31BP470BJMSAP and CDR31BP470BJWSAJ are qualified to MIL-PRF-55681 and are part of the military-grade CDR31 series with S-level failure rate classification (0.001%).

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. These components have unlimited shelf life and do not require special moisture control during storage or handling, provided standard ESD precautions are observed.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package with identical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum thickness of 0.051" (1.30mm). They are mechanically interchangeable on PCBs designed for 0805 surface mount components.
