Parameter Comparison

Engineering Selection Recommendations

The 1025-38K qualifies as a direct electrical and mechanical substitute for the 10M561K. Both components share identical inductance values, tolerance specifications, DC resistance ratings, Q factors, self-resonant frequencies, operating temperature ranges, and physical dimensions. The 1025-38K provides a higher current rating of 195 mA compared to the 10M561K at 185 mA, offering additional design margin in current-limited applications.

The 10M561K carries Active product status with RoHS Not Applicable classification and REACH Unaffected compliance. The 1025-38K is also Active product status but is classified as RoHS non-compliant and carries military specification designations (MIL-PRF-M15305, MS75084). Selection between these parts should account for regulatory compliance requirements specific to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Can the 1025-38K replace the 10M561K in existing designs?

A: Yes. Both components meet identical electrical specifications for inductance, tolerance, DC resistance, Q factor, and self-resonant frequency. Physical dimensions and mounting type are identical, enabling direct PCB substitution without layout modifications.

Q: What is the difference in current rating between these parts?

A: The 10M561K is rated at 185 mA maximum current, while the 1025-38K is rated at 195 mA. The 1025-38K provides 10 mA additional current capacity, which may be beneficial in applications operating near the current limit of the original design.

Q: Are there packaging differences between these parts?

A: The 10M561K is supplied in Tape & Reel (TR) packaging, while the 1025-38K is supplied in Cut Tape (CT) packaging. Both use identical axial through-hole component form factors suitable for automated and manual assembly processes.

Q: What compliance differences exist between these substitutes?

A: The 10M561K is RoHS Not Applicable. The 1025-38K is RoHS non-compliant and carries military specification designations. Applications requiring RoHS compliance should retain the 10M561K. Applications requiring military-grade specifications may prefer the 1025-38K.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the 10M561K and 1025-38K operate across the identical temperature range of -55°C to 105°C, ensuring thermal performance equivalence in temperature-sensitive applications.
