M39003/01-8213 Equivalent & Substitute Parts

Part Overview

The M39003/01-8213 is a 4.7 µF hermetically sealed tantalum capacitor rated for 50 V, manufactured by Vishay Sprague to MIL-PRF-39003/1 military specifications. This axial through-hole component is designed for high-reliability applications requiring stable capacitance performance across extended temperature ranges (-55°C to 125°C). The part is currently active in production with 745 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component procurement flexibility while maintaining performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M39003/01-8213 is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 4.7 µF (exact match required)
• Voltage rating: 50 V (exact match required)
• Mounting type: Through hole axial configuration
• Series compliance: MIL-PRF-39003/1 military specification
• Operating temperature range: -55°C to 125°C

Secondary Compatibility Parameters:

• Tolerance: ±5% or ±10% (wider tolerance acceptable in applications where tighter tolerance is not mandated)
• Package/case: Axial form factor
• Hermetically sealed construction

Substitute parts M39003/01-8214, M39003/01-2368, and M39003/01-6213 meet these criteria with documented variations in tolerance and failure rate specifications.

Parameter Comparison

Engineering Selection Recommendations

M39003/01-8214 (Vishay Sprague): Direct manufacturer alternative with identical physical dimensions and failure rate specification. Tolerance widens to ±10%, suitable for applications where ±5% tolerance is not a design requirement. Maintains MIL-PRF-39003/1 compliance and CSR13 series designation.

M39003/01-6213 (KEMET): Cross-manufacturer substitute meeting all electrical specifications with documented ESR of 2.5 Ohm. Physical length extends to 0.610" (15.49mm), requiring PCB layout verification for clearance. Failure rate specification is B (0.1%), representing higher reliability than the main part. Maintains full MIL-PRF-39003/1 compliance.

M39003/01-2368 (Vishay Sprague): Manufacturer alternative with ±10% tolerance and CSR13 series designation. Failure rate specification is M (1%), lower than the main part. Physical dimensions match the main part. Suitable for applications where relaxed tolerance and failure rate specifications are acceptable.

All substitute parts maintain active product status, military-grade hermetically sealed construction, and identical voltage and capacitance ratings. Selection depends on tolerance requirements, failure rate specifications, and physical space constraints within the application.

Frequently Asked Questions (FAQ)

Q: Can M39003/01-8214 replace M39003/01-8213 in all applications?

A: M39003/01-8214 is electrically compatible with identical capacitance, voltage rating, and physical dimensions. The tolerance specification widens from ±5% to ±10%. Substitution is valid only if the application design does not mandate ±5% tolerance. Both parts maintain identical failure rate (D, 0.001%) and MIL-PRF-39003/1 compliance.

Q: What is the significance of the different failure rates among substitute parts?

A: Failure rate specifications (D, B, M) indicate predicted reliability under defined operating conditions. M39003/01-8213 and M39003/01-8214 share failure rate D (0.001%). M39003/01-6213 specifies B (0.1%), and M39003/01-2368 specifies M (1%). Higher failure rates indicate lower predicted reliability. Selection should align with application reliability requirements and mission-critical status.

Q: Does the longer physical length of M39003/01-6213 affect substitution?

A: M39003/01-6213 measures 0.610" (15.49mm) in length compared to 0.474" (12.04mm) for the main part. This 0.136" (3.45mm) difference requires verification of available PCB space and clearance to adjacent components. Electrical performance remains equivalent; physical layout compatibility must be confirmed before substitution.

Q: Are all substitute parts RoHS compliant?

A: No. The main part M39003/01-8213 and all listed substitutes (M39003/01-8214, M39003/01-6213, M39003/01-2368) are RoHS non-compliant. All parts are REACH affected. Applications requiring RoHS compliance cannot use these components.

Q: What is the basis for substitution eligibility?

A: Substitution is based on matching capacitance (4.7 µF), voltage rating (50 V), mounting type (through-hole axial), operating temperature range (-55°C to 125°C), and MIL-PRF-39003/1 series compliance. Tolerance, failure rate, and ESR specifications may vary. Physical dimensions must accommodate PCB layout constraints.
