M39003/01-8024 Equivalent & Substitute Parts

Part Overview

The M39003/01-8024 is a 4.7 µF hermetically sealed tantalum capacitor rated at 10 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. The part is currently active in production with 987 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility within the same military specification series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M39003/01-8024 is determined by strict equivalence in the following parameters:

• Capacitance value: 4.7 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 10 V (exact match required)
• Type: Hermetically sealed tantalum (exact match required)
• Military specification compliance: MIL-PRF-39003/1, CSR13 series (exact match required)
• Mounting configuration: Through-hole axial (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)

The substitute part M39003/01-2254 meets all these criteria. Variations in physical dimensions, ESR characteristics, and failure rate classifications do not preclude substitution when the above parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the M39003/01-8024 and M39003/01-2254 are active production components compliant with MIL-PRF-39003/1 military specification. Selection between these parts should be based on:

• Availability and lead time requirements
• Inventory status (M39003/01-8024: 987 units; M39003/01-2254: 1072 units)
• Compliance requirements: Both parts are RoHS non-compliant and REACH affected, with identical ECCN and HTSUS classifications
• Physical space constraints: M39003/01-2254 has a longer axial length (0.422" vs. 0.286"), which may affect PCB layout compatibility

Frequently Asked Questions (FAQ)

Q: Can M39003/01-2254 be used as a direct replacement for M39003/01-8024?

A: Yes. Both parts meet identical electrical specifications (4.7 µF, ±10%, 10 V) and are certified to the same military standard (MIL-PRF-39003/1, CSR13). The primary consideration is physical dimensions, as the substitute part has a longer axial length.

Q: What is the difference in ESR between these parts?

A: The M39003/01-8024 does not specify an ESR value. The M39003/01-2254 specifies 8 Ohm ESR. ESR differences do not affect substitution eligibility when all electrical parameters are equivalent.

Q: Are there compliance differences between these parts?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (affected), ECCN classification (EAR99), and HTSUS code (8532.21.0020).

Q: Does the difference in failure rate affect substitution?

A: Failure rate classifications (D vs. M) reflect different test or application profiles but do not preclude substitution when all specified electrical and mechanical parameters match.

Q: What should I verify before substituting these parts in my design?

A: Confirm that the axial length difference (0.286" vs. 0.422") does not conflict with your PCB layout or mechanical constraints. Verify that your circuit design accommodates the specified operating temperature range (-55°C ~ 125°C) for both parts.
