Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 10M270K is determined by strict equivalence across the following critical parameters:

• Inductance value: 270 nH with ±10% tolerance
• Current rating: minimum 960 mA
• DC resistance: maximum 160 mOhm
• Q factor: 33 @ 25 MHz
• Self resonant frequency: 430 MHz
• Operating temperature range: -55°C to 125°C
• Core material: Phenolic
• Shielding configuration: Unshielded
• Mounting and package: Through-hole axial

The 1025-06K from API Delevan Inc. meets all specified electrical and mechanical parameters, maintaining identical inductance, tolerance, DC resistance, Q factor, and frequency characteristics. Physical dimensions and mounting configuration are equivalent. The substitute part is qualified under military specification MIL-PRF-M15305 and MS75083 series standards.

Engineering Selection Recommendations

The 10M270K remains the primary selection for applications requiring Gowanda Electronics sourcing or RoHS compliance status. The part is active in production with established supply availability.

The 1025-06K qualifies as a direct functional substitute when military specification compliance is required. This part is qualified to MIL-PRF-M15305 and MS75083 standards and maintains all critical electrical parameters. The 1025-06K carries RoHS non-compliant status; applications subject to RoHS requirements must retain the 10M270K. The 1025-06K is supplied in Cut Tape packaging with 1,956 units currently in stock, providing alternative sourcing when primary supply is constrained.

Both parts are REACH Unaffected and classified under ECCN EAR99 with HTSUS code 8504.50.8000.

Frequently Asked Questions (FAQ)

Q: Can the 1025-06K replace the 10M270K in all applications?

A: The 1025-06K is electrically and mechanically equivalent and will function identically in circuit applications. However, RoHS compliance status differs. The 10M270K is not subject to RoHS requirements, while the 1025-06K is RoHS non-compliant. Applications with RoHS mandates must use the 10M270K.

Q: What are the packaging differences between these parts?

A: The 10M270K is supplied in Tape & Reel (TR) packaging, while the 1025-06K is supplied in Cut Tape (CT) packaging. Both are through-hole axial components with identical physical dimensions and mounting footprints.

Q: Are there differences in current rating between these inductors?

A: The 10M270K is rated for 960 mA, while the 1025-06K is rated for 975 mA. Both exceed the minimum current requirement for equivalent circuit operation. The 1025-06K provides marginally higher current capacity.

Q: What certifications apply to the 1025-06K?

A: The 1025-06K is qualified to military specifications MIL-PRF-M15305 and MS75083. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts have identical axial through-hole mounting configurations and physical dimensions of 0.095" diameter × 0.250" length. PCB footprints and hole spacing are compatible for direct substitution.
