CDR31BP271BFMSAT Equivalent & Substitute Parts

Part Overview

The CDR31BP271BFMSAT is a 270 pF ±1% ceramic capacitor rated at 100V, manufactured by Vishay Vitramon under the military-grade CDR31 series compliant with MIL-PRF-55681. This surface-mount multilayer ceramic capacitor (MLCC) in 0805 (2012 Metric) package is designed for high-reliability applications with an S-level failure rate (0.001%) and operates across -55°C to 125°C. The part is currently active in production with 1112 pieces available in inventory. Substitute parts are identified when electrical parameters, mechanical dimensions, and reliability ratings remain equivalent, enabling procurement flexibility while maintaining circuit performance and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR31BP271BFMSAT is determined by strict equivalence across the following parameters:

• Capacitance value: 270 pF
• Tolerance: ±1%
• Voltage rating: 100V
• Temperature coefficient: BP
• Operating temperature range: -55°C to 125°C
• Package / Case: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCC
• Series compliance: Military, MIL-PRF-55681, CDR31
• Failure rate: S (0.001%)
• Moisture sensitivity level: 1 (Unlimited)

The CDR31BP271BFWSAT qualifies as a parametric equivalent based on identical electrical specifications and mechanical dimensions. Differences in packaging format (Cut Tape versus standard packaging) and RoHS compliance status do not affect electrical or thermal performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CDR31BP271BFMSAT and CDR31BP271BFWSAT are active production parts from Vishay Vitramon with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Packaging format requirements: CDR31BP271BFMSAT is available in standard packaging, while CDR31BP271BFWSAT is supplied in Cut Tape format.
• RoHS compliance: CDR31BP271BFMSAT is RoHS3 compliant; CDR31BP271BFWSAT is RoHS non-compliant. Regulatory requirements for the end application determine which part is appropriate.
• Inventory availability: CDR31BP271BFMSAT has 1112 pieces in stock; CDR31BP271BFWSAT has 2207 pieces in stock.

Both parts meet military-grade reliability standards with S-level failure rates and unlimited moisture sensitivity ratings, making them suitable for high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can CDR31BP271BFWSAT be used as a direct replacement for CDR31BP271BFMSAT in circuit design?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (270 pF), tolerance (±1%), voltage rating (100V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), and package dimensions (0805 / 2012 Metric). The primary consideration is RoHS compliance status and packaging format, which do not affect circuit performance.

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

A: The difference lies in packaging format and RoHS compliance. CDR31BP271BFMSAT is supplied in standard packaging and is RoHS3 compliant. CDR31BP271BFWSAT is supplied in Cut Tape format and is RoHS non-compliant. Both are from the same military-grade CDR31 series.

Q: Are both parts suitable for high-reliability applications?

A: Yes. Both parts carry an S-level failure rate (0.001%), comply with MIL-PRF-55681, and have unlimited moisture sensitivity ratings (MSL 1), making them appropriate for high-reliability circuit designs.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (standard versus Cut Tape) is a supply and handling consideration only and does not impact electrical characteristics, thermal performance, or reliability ratings.

Q: Which part should I select if RoHS compliance is required?

A: CDR31BP271BFMSAT is RoHS3 compliant and should be selected for applications with RoHS regulatory requirements.
