Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM2110-100K is determined by strict equivalence across the following critical parameters:

• Inductance value: 10 µH
• Current rating: 11.7 A minimum
• DC resistance: 7 mOhm maximum
• Tolerance: ±10%
• Core type and material: Toroidal, iron core
• Shielding configuration: Unshielded
• Operating temperature range: -55°C ~ 105°C minimum
• Mounting type: Surface mount
• Physical footprint: Nonstandard package matching 30.50mm x 25.40mm x 14.48mm dimensions

The PM2110-100K-RC meets all substitution criteria as a direct equivalent from the same manufacturer series (PM2110) with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The PM2110-100K-RC is a direct functional equivalent to the PM2110-100K with identical electrical performance and mechanical compatibility. The primary distinction is product status: the PM2110-100K is obsolete while the PM2110-100K-RC maintains active status with current manufacturing support.

The PM2110-100K-RC offers improved regulatory compliance, meeting ROHS3 standards compared to the non-compliant status of the original part. Both components maintain REACH unaffected status and EAR99 export classification.

For new designs or ongoing production requiring this inductor specification, the PM2110-100K-RC is the appropriate selection due to its active product status and enhanced compliance posture. Existing inventory of the PM2110-100K remains functionally suitable for applications where regulatory compliance is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can PM2110-100K-RC replace PM2110-100K in existing designs?

A: Yes. The PM2110-100K-RC is electrically and mechanically identical to the PM2110-100K. All electrical parameters, physical dimensions, and mounting characteristics are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between PM2110-100K and PM2110-100K-RC?

A: The components are electrically identical. The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). The PM2110-100K-RC is supplied in bulk packaging while the original part uses standard packaging.

Q: Are there any compatibility concerns with the nonstandard package?

A: No. Both parts use identical nonstandard packages with matching physical dimensions of 30.50mm x 25.40mm x 14.48mm. PCB footprints and mounting requirements are identical.

Q: What inductance tolerance should be expected?

A: Both parts are specified with ±10% inductance tolerance at 1 kHz test frequency. Circuit designs must account for this tolerance range in performance calculations.

Q: Is the PM2110-100K-RC suitable for high-temperature applications?

A: Both parts are rated for -55°C to 105°C operating temperature range. The PM2110-100K-RC maintains this specification and is suitable for the same thermal environment as the original part.

Q: What is the current handling capability?

A: Both parts are rated for 11.7 A continuous current with a maximum DC resistance of 7 mOhm. Thermal management and PCB layout should be designed accordingly for this current level.
