Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for M39003/01-5010 is determined by the following critical parameters:

• Capacitance Value: Must be 4.7 µF
• Voltage Rating: Must be 10 V or higher
• Type: Must be hermetically sealed tantalum
• Mounting Configuration: Must be through-hole axial
• Military Specification Compliance: Must conform to MIL-PRF-39003/1
• Operating Temperature Range: Must support -55°C to 125°C
• Failure Rate Classification: Must meet M (1%) or better

The M39003/01-2254 qualifies as a substitute based on matching capacitance, voltage rating, hermetic sealing, axial package configuration, military specification series, temperature range, and failure rate classification. Tolerance variation (±10% versus ±5%) and ESR specification (8 Ohm) represent allowable parameter differences within military standard tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both M39003/01-5010 and M39003/01-2254 maintain Active product status and comply with MIL-PRF-39003/1 military specifications. Selection between these components should account for the following factors:

M39003/01-5010 provides tighter capacitance tolerance at ±5%, suitable for applications requiring precise capacitance values within narrower specification bands.

M39003/01-2254 offers broader availability (1072 units in stock versus 790 units) and specifies ESR at 8 Ohm, providing defined equivalent series resistance characteristics. The ±10% tolerance remains within military specification limits for this component category.

Physical dimension differences exist: M39003/01-2254 measures 0.422" length compared to M39003/01-5010 at 0.286" length. PCB layout and mechanical clearance requirements must accommodate this 0.136" length differential.

Both components maintain identical voltage rating, operating temperature range, failure rate classification, and RoHS/REACH compliance status. Selection should prioritize circuit tolerance requirements and available board space.

Frequently Asked Questions (FAQ)

Q: Can M39003/01-2254 directly replace M39003/01-5010 in all applications?

A: Electrical substitution is valid when circuit design tolerates ±10% capacitance variation. Physical substitution requires verification of PCB layout clearance, as M39003/01-2254 is 0.136" longer. Both components meet identical military specifications and temperature performance.

Q: What is the significance of the ±5% versus ±10% tolerance difference?

A: Tolerance specification defines the allowable capacitance deviation from the nominal 4.7 µF value. M39003/01-5010 guarantees capacitance between 4.465 µF and 4.935 µF. M39003/01-2254 guarantees capacitance between 4.23 µF and 5.17 µF. Applications with tight capacitance requirements must use M39003/01-5010.

Q: Why does M39003/01-2254 specify ESR while M39003/01-5010 does not?

A: ESR specification indicates manufacturer-provided equivalent series resistance data. The 8 Ohm ESR value for M39003/01-2254 defines high-frequency impedance characteristics. Absence of ESR specification for M39003/01-5010 does not indicate performance deficiency; it reflects different manufacturer documentation practices within the same military specification series.

Q: Are there physical installation constraints when substituting between these parts?

A: Yes. The axial package diameter remains constant at 0.135", but length differs: M39003/01-5010 is 0.286" and M39003/01-2254 is 0.422". Verify PCB hole spacing, component clearance to adjacent parts, and mechanical support structures accommodate the longer substitute part.

Q: Do both parts comply with current military and environmental standards?

A: Both M39003/01-5010 and M39003/01-2254 are RoHS non-compliant and REACH-affected components, reflecting their military-grade tantalum capacitor classification. Both maintain Active product status and MIL-PRF-39003/1 certification.
