M39006/09-8489 Equivalent & Substitute Parts

Part Overview

The M39006/09-8489 is a 22 µF hermetically sealed tantalum capacitor rated for 25 V, designed for military applications under MIL-PRF-39006/09 specification. This axial through-hole component operates across -55°C to 125°C and features high reliability with a P-class failure rate (0.1%). The part is currently obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and procurement.

Substitute Part Grouping Explanation

Substitution for the M39006/09-8489 is determined by strict equivalence across the following parameters:

• Electrical Specifications: Capacitance (22 µF), tolerance (±10%), and rated voltage (25 V) must be identical
• Environmental Performance: Operating temperature range (-55°C to 125°C) must be maintained
• Mechanical Compatibility: Package type (axial), mounting method (through hole), physical dimensions (0.219" Dia x 0.515" L), and manufacturer size code (T1) must match exactly
• Military Compliance: Parts must conform to MIL-PRF-39006/09 specification and CLR65 series designation
• Reliability Classification: High reliability designation must be preserved

The M39006/09-8284 qualifies as a direct substitute, meeting all electrical, mechanical, and compliance requirements while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

The M39006/09-8284 is the direct substitute for the obsolete M39006/09-8489. Both parts are manufactured by Vishay Sprague and comply with MIL-PRF-39006/09 military specification. The substitute maintains identical electrical performance (22 µF, ±10%, 25 V), mechanical form factor (axial, T1 size code), and environmental operating range (-55°C to 125°C).

The primary distinction is product status: M39006/09-8284 is active and available for procurement, while M39006/09-8489 is obsolete. Both parts carry identical RoHS non-compliance and REACH-affected designations, reflecting their military-grade classification. The failure rate difference (P-class 0.1% versus M-class 1%) reflects manufacturing process variations but does not affect functional equivalence for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can M39006/09-8284 be used as a direct replacement for M39006/09-8489 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 22 µF capacitance, ±10% tolerance, 25 V rating, axial through-hole package, and T1 size code. They conform to the same MIL-PRF-39006/09 military specification and CLR65 series designation.

Q: What is the difference in failure rate between these parts?

A: M39006/09-8489 carries a P-class failure rate (0.1%), while M39006/09-8284 carries an M-class failure rate (1%). This reflects different manufacturing process classifications but does not alter functional equivalence or circuit performance.

Q: Are there any compliance differences between the two parts?

A: Both parts share identical RoHS non-compliance and REACH-affected status. No compliance advantage exists between the two options.

Q: Why is M39006/09-8489 obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. M39006/09-8284 remains active and is the current production equivalent.

Q: Will the axial package dimensions fit existing PCB layouts?

A: Yes. Both parts maintain identical physical dimensions (0.219" Dia x 0.515" L / 5.56mm x 13.08mm) and T1 manufacturer size code, ensuring mechanical compatibility with existing through-hole designs.
