Substitute Part Grouping Explanation

Substitution of the CDR31BP331BJMSAT is determined by strict equivalence across the following parameters:

• Capacitance value: 330 pF
• Tolerance: ±5%
• Rated voltage: 100V
• Temperature coefficient: BP
• Operating temperature range: -55°C ~ 125°C
• Package footprint: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCC
• Military series compliance: MIL-PRF-55681, CDR31

The substitute part CDR31BP331BJUS7185 meets all electrical and mechanical parameters required for direct substitution. Both parts share identical capacitance, voltage rating, temperature characteristics, and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the CDR31BP331BJMSAT and CDR31BP331BJUS7185 are active production parts meeting MIL-PRF-55681 military specifications. Selection between these parts should consider the following compliance factors:

The CDR31BP331BJMSAT is RoHS3 compliant, making it suitable for applications with RoHS requirements. The CDR31BP331BJUS7185 is RoHS non-compliant and REACH affected, which may restrict its use in certain regulated markets or applications with strict environmental compliance mandates.

Both parts maintain identical electrical performance, military-grade reliability ratings, and physical compatibility. The choice between manufacturers depends on supply chain availability, compliance certifications required by the end application, and procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can CDR31BP331BJUS7185 be used as a direct replacement for CDR31BP331BJMSAT?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical capacitance (330 pF), voltage rating (100V), temperature coefficient (BP), operating temperature range (-55°C ~ 125°C), and 0805 package footprint. However, compliance differences must be evaluated for your specific application requirements.

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

A: The CDR31BP331BJMSAT is supplied in standard packaging, while the CDR31BP331BJUS7185 is supplied in Tape & Reel (TR) format. Both maintain the same component dimensions and electrical characteristics. Tape & Reel packaging is typically used for automated assembly processes.

Q: Are there any compliance differences I should be aware of?

A: Yes. The CDR31BP331BJMSAT is RoHS3 compliant, while the CDR31BP331BJUS7185 is RoHS non-compliant and REACH affected. If your application or market requires RoHS compliance, the CDR31BP331BJMSAT is the appropriate choice.

Q: Do both parts meet military specifications?

A: Yes. Both parts are manufactured to MIL-PRF-55681 military standards within the CDR31 series and maintain the same S-level (0.001%) failure rate classification.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
