PM2110-101K Equivalent & Substitute Parts

Part Overview

The PM2110-101K is a 100 µH unshielded toroidal inductor manufactured by Bourns Inc., rated for 5.4 A with a maximum DC resistance of 32 mOhm. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. The PM2110 series provides surface-mount toroidal inductors with iron cores suitable for applications requiring moderate inductance values and current handling capacity.

Substitute Part Grouping Explanation

Substitution of the PM2110-101K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part PM2110-101K-RC maintains identical specifications for inductance (100 µH), tolerance (±10%), current rating (5.4 A), DC resistance (32 mOhm maximum), core material (iron), shielding configuration (unshielded), operating temperature range (-55°C to 105°C), and physical dimensions (30.50 mm × 25.40 mm × 15.75 mm maximum height). The primary distinction is product status: PM2110-101K is obsolete while PM2110-101K-RC is active, and packaging differs (standard versus bulk). Both components are tested at 1 kHz inductance frequency and are classified as nonstandard package types within the PM2110 series.

Parameter Comparison

Engineering Selection Recommendations

The PM2110-101K-RC is the direct equivalent for the obsolete PM2110-101K. All electrical and mechanical parameters are identical, ensuring functional interchangeability in circuit applications. The primary advantage of PM2110-101K-RC is its active product status, ensuring continued availability and manufacturing support. Additionally, PM2110-101K-RC meets ROHS3 compliance requirements, whereas the original PM2110-101K is RoHS non-compliant. For new designs or component replenishment, PM2110-101K-RC is the appropriate selection. Both parts maintain identical moisture sensitivity classification (MSL 1) and REACH unaffected status, with no restrictions on environmental compliance for this parameter set.

Frequently Asked Questions (FAQ)

Q: Can PM2110-101K-RC be used as a direct replacement for PM2110-101K?

A: Yes. PM2110-101K-RC is electrically and mechanically equivalent to PM2110-101K across all specified parameters: 100 µH inductance, ±10% tolerance, 5.4 A current rating, 32 mOhm maximum DC resistance, iron core, unshielded configuration, and identical physical dimensions. Direct substitution is valid for all applications.

Q: What is the difference between PM2110-101K and PM2110-101K-RC?

A: The primary differences are product status and compliance. PM2110-101K is obsolete with RoHS non-compliant status, while PM2110-101K-RC is active and ROHS3 compliant. Packaging differs (standard versus bulk), but electrical and mechanical specifications are identical.

Q: Are there any thermal or frequency limitations when substituting these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 105°C) and are tested at the same inductance frequency (1 kHz). No thermal or frequency derating applies to the substitution.

Q: Does the nonstandard package type affect substitution compatibility?

A: No. Both PM2110-101K and PM2110-101K-RC use identical nonstandard package dimensions (30.50 mm × 25.40 mm × 15.75 mm maximum height). PCB layout and mechanical mounting are unchanged.

Q: Is RoHS compliance a concern when substituting PM2110-101K with PM2110-101K-RC?

A: If your application or market requires RoHS compliance, PM2110-101K-RC (ROHS3 compliant) is the appropriate choice. PM2110-101K is RoHS non-compliant and should not be used in RoHS-regulated applications.
