Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 10M102K is determined by the following critical parameters:

• Inductance Value: Must be 10 µH with ±10% tolerance
• Current Rating: Minimum 130 mA; higher ratings are acceptable
• DC Resistance: Maximum 3.7 Ohm; lower values are acceptable
• Q Factor: 55 @ 7.9 MHz
• Self Resonant Frequency: 50 MHz
• Operating Temperature: -55°C to 105°C
• Shielding Configuration: Unshielded
• Mounting and Package: Through hole axial with 0.095" Dia × 0.250" L dimensions

The API Delevan Inc. 1025-44K meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The 1025-44K from API Delevan Inc. is a direct functional equivalent to the 10M102K. Both components share identical inductance values, Q factors, self-resonant frequencies, operating temperature ranges, and physical dimensions. The 1025-44K provides superior electrical performance with a higher current rating (144 mA versus 130 mA) and lower DC resistance (3.3 Ohm versus 3.7 Ohm maximum).

The 10M102K carries RoHS Not Applicable status, while the 1025-44K is RoHS non-compliant. Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8504.50.8000. 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 1025-44K replace the 10M102K in existing designs?

A: Yes. Both inductors share identical inductance values (10 µH ±10%), Q factors (55 @ 7.9 MHz), self-resonant frequencies (50 MHz), operating temperature ranges (-55°C to 105°C), and physical dimensions (0.095" Dia × 0.250" L). The 1025-44K provides higher current capacity and lower DC resistance, making it electrically superior for the same footprint.

Q: Are there dimensional differences between these parts?

A: No. Both the 10M102K and 1025-44K have identical axial package dimensions of 0.095" diameter by 0.250" length (2.41 mm × 6.35 mm). They are mechanically interchangeable in through-hole PCB layouts.

Q: What is the difference in current handling capability?

A: The 10M102K is rated for 130 mA continuous current, while the 1025-44K is rated for 144 mA. The 1025-44K can handle 14 mA additional current without saturation, providing design margin in current-limited applications.

Q: How do the DC resistance specifications compare?

A: The 10M102K has a maximum DC resistance of 3.7 Ohm, while the 1025-44K has a maximum of 3.3 Ohm. Lower DC resistance in the 1025-44K reduces resistive losses and heat generation in the inductor.

Q: Are there compliance differences between these parts?

A: The 10M102K is RoHS Not Applicable, while the 1025-44K is RoHS non-compliant. Both are REACH Unaffected. Applications requiring RoHS compliance should specify the 10M102K or verify exemption applicability for the 1025-44K in the target market.

Q: What packaging formats are available?

A: The 10M102K is supplied in standard packaging, while the 1025-44K is available in Cut Tape (CT) format. Both are through-hole axial components suitable for manual or automated PCB assembly.
