Equivalent & Substitute Parts for M39003/01-5012

Part Overview

The M39003/01-5012 is a 33 µF hermetically sealed tantalum capacitor rated at 10 V, designed for military applications under MIL-PRF-39003/1 specification. This axial through-hole component operates across a temperature range of -55°C to 125°C and is classified as a high-reliability component with a 1% failure rate (M-level). The part is currently active in production with 911 units available in inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowable specifications for this product category, enabling component interchangeability in circuit designs where the primary part becomes unavailable or when alternative reliability grades are acceptable.

Substitute Part Grouping Explanation

Substitution eligibility for the M39003/01-5012 is determined by strict adherence to the following parameters:

• Capacitance Value: Must be 33 µF (no deviation)
• Voltage Rating: Must be 10 V or higher (equal or greater)
• Type: Must be hermetically sealed tantalum capacitor
• Mounting Type: Must be through-hole axial configuration
• Physical Dimensions: Must match 0.185" Dia x 0.474" L (4.70mm x 12.04mm)
• Operating Temperature Range: Must support -55°C to 125°C
• Series Compliance: Must conform to MIL-PRF-39003/1 specification

The M39003/01-6029 qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. The tolerance specification differs (±10% versus ±5%), which is an allowable variation within military tantalum capacitor standards. The failure rate classification differs (B-level at 0.1% versus M-level at 1%), representing an improvement in reliability performance.

Parameter Comparison

Engineering Selection Recommendations

Both M39003/01-5012 and M39003/01-6029 are active production components manufactured by Vishay Sprague and comply with MIL-PRF-39003/1 military specifications. Both parts are RoHS non-compliant and REACH-affected, with identical ECCN (EAR99) and HTSUS (8532.21.0020) classifications.

The M39003/01-6029 substitute part offers improved reliability performance with a B-level failure rate (0.1%) compared to the M-level failure rate (1%) of the primary part, while maintaining identical electrical and mechanical specifications. The tolerance specification of ±10% on the substitute part remains within acceptable military tantalum capacitor standards.

Selection between these parts should be based on circuit design requirements for tolerance specification and reliability performance level, with both parts providing equivalent functional performance in applications requiring 33 µF capacitance at 10 V with hermetically sealed construction.

Frequently Asked Questions (FAQ)

Q: Can M39003/01-6029 be used as a direct replacement for M39003/01-5012?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (10 V), physical dimensions (0.185" Dia x 0.474" L), mounting type (through-hole axial), and operating temperature range (-55°C to 125°C). The tolerance difference (±10% versus ±5%) and improved failure rate (B-level versus M-level) do not prevent direct substitution in circuit applications.

Q: What is the significance of the tolerance difference between these parts?

A: The M39003/01-5012 specifies ±5% tolerance, while the M39003/01-6029 specifies ±10% tolerance. Both tolerances are standard for military-grade tantalum capacitors. Circuit designs requiring tighter capacitance accuracy should specify the ±5% part; applications with broader tolerance requirements can utilize the ±10% substitute.

Q: Does the failure rate difference affect substitution eligibility?

A: No. The M39003/01-6029 exhibits a superior failure rate (B-level at 0.1%) compared to the M39003/01-5012 (M-level at 1%). This represents improved reliability performance and does not restrict substitution. Applications requiring specific failure rate classifications should reference design specifications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in identical axial configuration with dimensions of 0.185" Dia x 0.474" L (4.70mm x 12.04mm), ensuring mechanical compatibility in through-hole PCB layouts.

Q: What compliance certifications apply to both parts?

A: Both M39003/01-5012 and M39003/01-6029 are manufactured under MIL-PRF-39003/1 military specification with CSR13 series designation. Both parts are RoHS non-compliant and REACH-affected, with ECCN classification EAR99 and HTSUS code 8532.21.0020.
