Substitute Part Grouping Explanation

Substitution eligibility for M39003/01-8073 is determined by strict alignment of the following parameters:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage - Rated: 20 V (exact match required)
• Type: Hermetically Sealed (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Manufacturer Size Code: A (exact match required)
• Series Qualification: MIL-PRF-39003/1 (exact match required)

Substitute parts M39003/01-6073 (Vishay Sprague) and M39003/01-2763 (KEMET) meet all mandatory electrical and mechanical parameters. Variations in failure rate classification and physical length do not preclude substitution when circuit board layout permits.

Parameter Comparison

Engineering Selection Recommendations

Both M39003/01-6073 and M39003/01-2763 are qualified substitutes for M39003/01-8073 based on electrical and mechanical parameter alignment with MIL-PRF-39003/1 military specifications.

M39003/01-6073 (Vishay Sprague): Maintains identical physical dimensions to the main part. Failure rate classification differs (B vs. D), reflecting different reliability grades within the military specification. Both parts meet the same operating temperature and voltage requirements.

M39003/01-2763 (KEMET): Meets all electrical parameters and military qualification requirements. Physical length is 0.422" (10.72mm) compared to 0.286" (7.26mm) for the main part. ESR is specified at 7 Ohm. Circuit board layout must accommodate the increased axial length. Failure rate classification is R (0.01%), positioned between the main part and M39003/01-6073.

All three parts carry identical RoHS non-compliant and REACH Affected designations. Selection should prioritize availability, physical space constraints, and failure rate requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can M39003/01-6073 be used as a direct replacement for M39003/01-8073?

A: Yes. Both parts share identical electrical specifications (2.2 µF, ±10%, 20 V), hermetically sealed construction, operating temperature range (-55°C to 125°C), axial through-hole mounting, and physical dimensions (0.135" Dia x 0.286" L). Both are qualified to MIL-PRF-39003/1. The difference in failure rate classification does not affect functional compatibility.

Q: What is the primary difference between M39003/01-2763 and the main part?

A: M39003/01-2763 is electrically equivalent but has a longer axial length (0.422" vs. 0.286"). The ESR is specified at 7 Ohm. Circuit board layout must accommodate this dimensional difference. All electrical parameters and military qualifications remain aligned.

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

A: Yes. M39003/01-8073, M39003/01-6073, and M39003/01-2763 are all qualified to MIL-PRF-39003/1 military specifications for hermetically sealed tantalum capacitors.

Q: Does the failure rate difference affect substitution eligibility?

A: Failure rate classification reflects reliability grade within the military specification but does not alter electrical or mechanical compatibility. Selection based on failure rate depends on application-specific reliability requirements.

Q: Can these parts be used in RoHS-compliant applications?

A: No. All three parts are designated RoHS non-compliant and REACH Affected. Applications requiring RoHS compliance cannot use these components.

Q: What is the significance of the Manufacturer Size Code "A"?

A: Size Code A is a standardized designation within MIL-PRF-39003/1 that defines the physical envelope and electrical characteristics. All three parts share this code, confirming dimensional and performance alignment.
