Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 10M181K is determined by strict alignment of the following critical parameters:

• Inductance value: 1.8 µH with ±10% tolerance
• Current rating: minimum 455 mA
• DC resistance: 300 mOhm maximum
• Q factor: 30 @ 7.9 MHz
• Self-resonant frequency: 125 MHz
• Operating temperature range: -55°C ~ 105°C
• Mounting configuration: Through hole, axial package
• Physical dimensions: 0.095" Dia x 0.250" L (2.41mm x 6.35mm)
• Shielding type: Unshielded

The 1025-26K from API Delevan Inc. meets all electrical and mechanical substitution criteria for the 10M181K. Both components share identical inductance, tolerance, DC resistance, Q factor, self-resonant frequency, operating temperature range, and physical dimensions. The 1025-26K provides a current rating of 480 mA, which exceeds the 10M181K requirement of 455 mA, ensuring compatibility in applications where the 10M181K is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 10M181K and 1025-26K are active production components suitable for new designs and replacement applications. The 10M181K carries RoHS Not Applicable status and REACH Unaffected certification. The 1025-26K is RoHS non-compliant and REACH Unaffected. Selection between these components should be based on regulatory compliance requirements specific to the end application. The 1025-26K qualifies to military specification MIL-PRF-M15305 and MS75084, making it suitable for applications requiring military-grade inductors. The 10M181K is available in Tape & Reel packaging, while the 1025-26K is supplied in Cut Tape packaging. Both components are classified under ECCN EAR99 and HTSUS 8504.50.8000.

Frequently Asked Questions (FAQ)

Q: Can the 1025-26K replace the 10M181K in all applications?

A: The 1025-26K meets all electrical and mechanical parameters required for substitution. However, regulatory compliance differences must be evaluated. The 10M181K is RoHS Not Applicable, while the 1025-26K is RoHS non-compliant. Applications subject to RoHS requirements should use the 10M181K.

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

A: The 10M181K has a current rating of 455 mA, while the 1025-26K is rated for 480 mA. The 1025-26K's higher current rating provides additional design margin and does not restrict its use in applications designed for the 10M181K.

Q: Are there packaging differences between these substitutes?

A: Yes. The 10M181K is supplied in Tape & Reel (TR) packaging, while the 1025-26K is supplied in Cut Tape (CT) packaging. Both are through-hole axial components with identical physical dimensions and mounting requirements.

Q: What military specifications does the 1025-26K meet?

A: The 1025-26K qualifies to MIL-PRF-M15305 and MS75084 military specifications, making it suitable for defense and aerospace applications requiring military-grade components.

Q: Are both parts suitable for the full operating temperature range specified?

A: Yes. Both the 10M181K and 1025-26K operate across the identical temperature range of -55°C to 105°C, ensuring thermal compatibility in applications across this range.
