CDR34BP103AFMSAT Equivalent & Substitute Parts

Part Overview

The CDR34BP103AFMSAT is a 10000 pF (0.01 µF) ceramic capacitor rated for 50V with ±1% tolerance, manufactured by Vishay Vitramon. This military-grade multilayer ceramic capacitor (MLCC) is designed for high-reliability applications requiring MIL-PRF-55681 compliance. The part features a BP temperature coefficient with an operating range of -55°C to 125°C and is housed in a 1812 (4532 Metric) surface-mount package. With an active product status and S-level failure rate (0.001%), this component is suitable for aerospace, defense, and mission-critical electronic systems where component reliability and traceability are essential.

Substitute Part Grouping Explanation

Substitution for the CDR34BP103AFMSAT is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 10000 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 50V (exact match required)
• Temperature Coefficient: BP (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Series Compliance: Military, MIL-PRF-55681, CDR34 (exact match required)

The identified substitute part CDR34BP103AFUS7185 meets all electrical and mechanical parameters specified above, making it a direct parametric equivalent. Substitution is valid only when all parameters align exactly with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the CDR34BP103AFMSAT and CDR34BP103AFUS7185 are active military-grade ceramic capacitors meeting MIL-PRF-55681 specifications. Selection between these parts should be based on the following compliance and regulatory factors:

CDR34BP103AFMSAT (Vishay Vitramon): This part is ROHS3 compliant, making it suitable for applications requiring RoHS certification. The part carries no REACH restrictions and is available in standard packaging configurations.

CDR34BP103AFUS7185 (KEMET): This part is RoHS non-compliant and is marked as REACH Affected. Selection of this part is appropriate only for applications where RoHS compliance is not required and REACH restrictions do not apply. The part is supplied in Tape & Reel (TR) packaging, which may be preferred for high-volume automated assembly operations.

Component selection should align with the regulatory requirements of the end application and supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can CDR34BP103AFUS7185 be used as a direct replacement for CDR34BP103AFMSAT?

A: Yes, from an electrical and mechanical standpoint. Both parts are parametrically equivalent with identical capacitance (10000 pF), tolerance (±1%), voltage rating (50V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), package (1812/4532 Metric), and military series compliance (MIL-PRF-55681). However, regulatory compliance differences must be evaluated. The CDR34BP103AFMSAT is ROHS3 compliant, while the CDR34BP103AFUS7185 is RoHS non-compliant and REACH Affected. Selection depends on application requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact equivalence in: capacitance value (10000 pF), tolerance (±1%), voltage rating (50V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), package type (1812/4532 Metric), mounting type (Surface Mount MLCC), and military series compliance (MIL-PRF-55681, CDR34). All parameters must match exactly.

Q: Are there packaging differences between these parts?

A: The CDR34BP103AFMSAT is supplied in standard packaging, while the CDR34BP103AFUS7185 is supplied in Tape & Reel (TR) format. Both parts have identical physical dimensions (0.177" L x 0.126" W / 4.50mm x 3.20mm) and thickness (0.059" / 1.50mm), ensuring mechanical compatibility in PCB assembly.

Q: What is the failure rate specification for these parts?

A: Both parts carry an S-level failure rate of 0.001%, meeting military-grade reliability standards for high-reliability applications.

Q: Are both parts currently in production?

A: Yes, both the CDR34BP103AFMSAT and CDR34BP103AFUS7185 maintain active product status with current inventory availability.
