• DC Resistance: Both maintain 4.6Ohm maximum
• Current Rating: The substitute supports 140 mA, exceeding the main part's 135 mA requirement
• Quality Factor: Both deliver Q of 50 @ 2.5MHz
• Self-Resonant Frequency: Both rated at 20MHz
• Operating Temperature: Identical range of -55°C ~ 105°C
• Mounting Configuration: Both are through-hole axial components
• Physical Dimensions: Identical at 0.095" Dia x 0.250" L (2.41mm x 6.35mm)
• Shielding: Both are unshielded designs

The substitute part is qualified for military applications under MIL-PRF-M15305 and MS75084 specifications, with 3,200 units currently in stock.

Parameter Comparison

Engineering Selection Recommendations

Both the 10M272K and 1025-54K are active production components suitable for direct substitution in through-hole axial inductor applications. The 10M272K carries RoHS Not Applicable status, while the 1025-54K is RoHS non-compliant. Selection between these parts should be based on regulatory requirements specific to the end application. The 1025-54K offers military qualification under MIL-PRF-M15305 and MS75084, making it suitable for defense and aerospace applications where such certifications are mandated. Both parts maintain REACH Unaffected status and carry EAR99 ECCN classification. The substitute part's higher current rating of 140 mA provides additional design margin over the main part's 135 mA specification.

Frequently Asked Questions (FAQ)

Q: Can the 1025-54K replace the 10M272K in existing designs?

A: Yes. Both parts share identical inductance values, tolerance, DC resistance, quality factor, self-resonant frequency, operating temperature range, and physical dimensions. The substitute supports a higher current rating, ensuring compatibility with existing circuit requirements.

Q: What is the difference in packaging between these parts?
