M39003/01-5290 Equivalent & Substitute Parts

Part Overview

The M39003/01-5290 is a 10 µF hermetically sealed tantalum capacitor rated for 50 V, manufactured by Vishay Sprague to military specification MIL-PRF-39003/1. This component is designed for high-reliability applications requiring axial through-hole mounting with operating temperature range from -55°C to 125°C. The part is currently active with 803 units in stock. Equivalent and substitute parts are identified when electrical parameters (capacitance, voltage rating, tolerance) and mechanical specifications (package type, mounting configuration, size) align within acceptable engineering tolerances for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for M39003/01-5290 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 10 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Type: Hermetically Sealed Tantalum (exact match required)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole Axial (exact match required)
• Package / Case: Axial (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Series: Military, MIL-PRF-39003/1, CSR13 (exact match required)

Tolerance Consideration: The main part specifies ±5% tolerance. Substitute parts with ±10% tolerance remain functionally equivalent for applications where the tighter tolerance of the original is not a design-critical requirement, as the 10% tolerance still encompasses the 5% specification band.

Identified Substitutes:

• M39003/01-8224 (Vishay Sprague, ±10% tolerance, Failure Rate D)
• M39003/01-2854 (Vishay Sprague, ±10% tolerance, Failure Rate R)
• M39003/01-6224 (KEMET, ±10% tolerance, Failure Rate B)

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with military specification MIL-PRF-39003/1. Selection among substitutes should be based on the following factors:

M39003/01-8224 (Vishay Sprague): Identical physical dimensions to the main part. Failure rate D (0.001%) provides superior reliability performance. Tolerance relaxation to ±10% is acceptable for applications where the original ±5% specification is not design-critical.

M39003/01-2854 (Vishay Sprague): Identical physical dimensions to the main part. Failure rate R (0.01%) provides intermediate reliability performance. Maintains Vishay Sprague manufacturing continuity.

M39003/01-6224 (KEMET): Length dimension increases to 0.822" L (20.88mm) compared to 0.686" L (17.42mm) for the main part. This dimensional difference requires verification of available board space and lead routing clearance. Failure rate B (0.1%) matches the main part specification. ESR specification of 1.6Ohm is provided. Packaging format differs (Tray versus Bulk).

All substitute parts are RoHS non-compliant and REACH affected, consistent with the main part classification.

Frequently Asked Questions (FAQ)

Q: Can M39003/01-6224 be used as a direct replacement for M39003/01-5290?

A: M39003/01-6224 is electrically equivalent but has a longer axial length (0.822" versus 0.686"). Physical board layout compatibility must be verified before substitution. The increased length may affect lead routing and component spacing.

Q: What is the significance of tolerance differences between ±5% and ±10%?

A: The main part M39003/01-5290 specifies ±5% tolerance, while all substitute parts specify ±10% tolerance. For applications where capacitance value is non-critical or where circuit design accommodates the wider tolerance band, ±10% substitutes are acceptable. Applications requiring tight capacitance control should retain the original ±5% specification.

Q: Are all substitute parts qualified to MIL-PRF-39003/1?

A: Yes. All identified substitutes are qualified to military specification MIL-PRF-39003/1 and operate within the -55°C to 125°C temperature range specified for the main part.

Q: What do the failure rate codes mean?

A: Failure rate codes indicate reliability performance under MIL-PRF-39003/1 qualification. The main part specifies P (0.1%). Substitutes offer varying failure rates: M39003/01-8224 provides D (0.001%), M39003/01-2854 provides R (0.01%), and M39003/01-6224 provides B (0.1%). Lower failure rates indicate superior reliability performance.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Bulk versus Tray) does not affect electrical or mechanical compatibility. It reflects supplier inventory and handling configuration only. Component performance and specifications remain identical regardless of packaging format.

Q: Can substitutes be mixed in the same assembly?

A: All substitute parts meet identical electrical and mechanical specifications for the core application requirements. However, assembly documentation and design verification should confirm that mixed part numbers are acceptable for the specific application.
