Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for M39003/01-5286 is determined by strict equivalence in the following parameters:

• Capacitance Value: Must be 4.7 µF (no deviation)
• Voltage Rating: Must be 50 V or higher (50 V minimum)
• Type: Must be hermetically sealed tantalum
• Mounting: Must be through-hole axial configuration
• Military Specification: Must comply with MIL-PRF-39003/1
• Operating Temperature: Must support -55°C to 125°C range
• Tolerance: Acceptable range ±5% to ±10% (tighter tolerance preferred for direct equivalence)

The identified substitutes meet these core electrical and mechanical requirements. Tolerance variations (±5% vs ±10%) and manufacturer differences (Vishay Sprague vs KEMET) are permitted within military specification allowances. Physical dimensions may vary slightly within the axial package category while maintaining the same mounting footprint classification.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and comply with MIL-PRF-39003/1 military specification requirements. Selection among M39003/01-8214, M39003/01-6213, and M39003/01-2368 is based on the following provided parameters:

M39003/01-8214 (Vishay Sprague): Identical physical dimensions to the main part (0.185" Dia x 0.474" L). Tolerance specification is ±10%, which is acceptable within military allowances. Failure rate D (0.001%) indicates superior reliability performance compared to the main part.

M39003/01-6213 (KEMET): Matches tolerance specification (±5%) with the main part. Physical length is 0.610" L, representing a dimensional variation within the axial package category. ESR specification of 2.5 Ohm is provided. Failure rate B (0.1%) aligns with the main part classification.

M39003/01-2368 (Vishay Sprague): Identical physical dimensions to the main part (0.185" Dia x 0.474" L). Tolerance specification is ±10%. Failure rate M (1%) indicates lower reliability performance relative to other substitutes.

All parts are RoHS non-compliant and REACH Affected, consistent with the main part compliance profile. Selection should prioritize application requirements for tolerance precision, reliability grade, and physical space constraints.

Frequently Asked Questions (FAQ)

Q: Can M39003/01-8214 be used as a direct replacement for M39003/01-5286?

A: Yes. M39003/01-8214 meets all core electrical parameters (4.7 µF, 50 V, hermetically sealed tantalum) and maintains identical physical dimensions (0.185" Dia x 0.474" L). The ±10% tolerance is acceptable within MIL-PRF-39003/1 specification allowances. Both are Vishay Sprague products in the CSR13 series.

Q: What is the significance of the dimensional difference in M39003/01-6213?

A: M39003/01-6213 has a length of 0.610" L compared to 0.474" L in the main part and other substitutes. This represents a physical space consideration for board layout and component placement. The diameter remains identical at 0.185". Verify available board space before selection.

Q: How do tolerance specifications affect substitution?

A: The main part M39003/01-5286 specifies ±5% tolerance. Substitutes M39003/01-8214 and M39003/01-2368 specify ±10% tolerance, which is a wider tolerance band. M39003/01-6213 maintains ±5% tolerance matching the main part. Applications requiring tighter capacitance accuracy should prioritize ±5% tolerance parts.

Q: Are all substitutes qualified under the same military specification?

A: Yes. All parts including the main component are qualified under MIL-PRF-39003/1 and belong to the CSR13 series. All maintain Active product status and support the -55°C to 125°C operating temperature range.

Q: What do the failure rate designations mean?

A: Failure rate classifications (P, D, B, M) indicate reliability grades under military specification. M39003/01-8214 (D: 0.001%) represents the highest reliability. M39003/01-5286 and M39003/01-6213 (both 0.1%) represent equivalent mid-range reliability. M39003/01-2368 (M: 1%) represents lower reliability performance. Selection should align with application criticality requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for all substitutes within the specified parameter ranges. Physical interchangeability requires verification of board layout constraints, particularly for M39003/01-6213 due to its increased length. Consult design documentation and perform board-level validation before implementation.
