Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 10M104K are qualified based on strict equivalence of the following electrical and mechanical parameters:

• Inductance value: 1 mH
• Inductance tolerance: ±10%
• Current rating: 28 mA minimum
• DC resistance: 72Ohm maximum
• Q factor: 30 @ 790kHz
• Self resonant frequency: 3.4MHz
• Operating temperature range: -55°C ~ 105°C
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through Hole
• Package configuration: Axial
• Physical dimensions: 0.095" Dia x 0.250" L (2.41mm x 6.35mm)

The 1025-92K from API Delevan Inc. meets all specified electrical and mechanical parameters and is therefore qualified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The 10M104K is an active product with established supply availability. The 1025-92K qualifies as an electrical and mechanical equivalent based on identical inductance, current rating, DC resistance, Q factor, resonant frequency, temperature range, core material, and package dimensions.

The 10M104K carries RoHS Not Applicable status, while the 1025-92K is RoHS non-compliant. Both parts maintain REACH Unaffected status and share the same ECCN (EAR99) and HTSUS (8504.50.8000) classifications. Selection between these parts should account for regulatory compliance requirements specific to the application and end-use market.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the 10M104K?

A: Substitution requires matching inductance (1 mH ±10%), current rating (28 mA), DC resistance (72Ohm maximum), Q factor (30 @ 790kHz), self resonant frequency (3.4MHz), operating temperature range (-55°C ~ 105°C), core material (ferrite), shielding (unshielded), mounting type (through hole), and axial package dimensions (0.095" Dia x 0.250" L).

Q: Are the 10M104K and 1025-92K physically interchangeable?

A: Yes. Both parts share identical axial package dimensions of 0.095" Dia x 0.250" L (2.41mm x 6.35mm) and through-hole mounting configuration, enabling direct board-level substitution.

Q: What is the difference in RoHS compliance between these parts?

A: The 10M104K carries RoHS Not Applicable status, while the 1025-92K is RoHS non-compliant. Applications subject to RoHS directives should use the 10M104K or confirm regulatory exemptions before selecting the 1025-92K.

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

A: Yes. Both the 10M104K and 1025-92K operate across -55°C to 105°C, maintaining identical electrical performance across this temperature range.

Q: What is the inventory status for substitute parts?

A: The 10M104K has 1161 pieces in stock. The 1025-92K has 5454 pieces available, providing alternative supply sourcing if needed.
