ELL-6PM101M Equivalent & Substitute Parts

Part Overview

The ELL-6PM101M is a 100 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 320 mA continuous current with 970mOhm DC resistance. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The nonstandard package and specific electrical characteristics require careful evaluation of alternative components to ensure functional compatibility in surface mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELL-6PM101M is based on the following critical parameters:

• Inductance Value: 100 µH ±20% tolerance
• Current Rating: Minimum 320 mA continuous current capability
• DC Resistance: Maximum acceptable DCR to maintain circuit performance
• Shielding: Shielded construction required
• Mounting: Surface mount, nonstandard 6.00mm x 6.00mm footprint
• Test Frequency: 100 kHz inductance measurement standard

The substitute part SLF6028T-101MR42-PF from TDK Corporation meets these core electrical and mechanical requirements while offering improved current handling and lower DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SLF6028T-101MR42-PF serves as a functional equivalent for the obsolete ELL-6PM101M based on matching inductance value, tolerance, shielding, and footprint dimensions. The substitute provides superior electrical performance with doubled current rating (640 mA vs. 320 mA) and reduced DC resistance (516mOhm Max vs. 970mOhm), resulting in lower power dissipation and improved thermal characteristics.

The primary design consideration is the increased seated height of 3.00mm compared to the original 2.00mm maximum. PCB layout and component clearance must be verified to accommodate this dimensional difference. Both components maintain MSL 1 moisture sensitivity classification and operate within compatible frequency ranges at 100 kHz inductance measurement.

The TDK substitute carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the SLF6028T-101MR42-PF directly replace the ELL-6PM101M without circuit modification?

A: The electrical characteristics are compatible for circuits designed around the original 320 mA rating. The improved current handling and lower DC resistance of the substitute will not degrade circuit performance. However, the increased height (3.00mm vs. 2.00mm) requires verification of PCB clearance and component placement constraints.

Q: What is the significance of the ±20% inductance tolerance for substitution?

A: Both the main part and substitute share identical ±20% tolerance at 100 kHz test frequency. This tolerance band ensures that inductance values remain within acceptable circuit operating parameters for applications designed around the 100 µH nominal specification.

Q: Why is the DC resistance difference important?

A: The substitute's lower DC resistance (516mOhm Max vs. 970mOhm) reduces resistive losses and heat generation during operation. For circuits operating at or near the 320 mA rating, this improvement enhances efficiency and thermal performance without requiring design changes.

Q: Are there any compliance or regulatory differences between these parts?

A: The TDK substitute provides explicit RoHS3 compliance and REACH unaffected status. Both components maintain MSL 1 classification. The substitute's documented compliance status may be advantageous for procurement and regulatory documentation requirements.

Q: What should be verified before implementing the substitute in production?

A: Verify PCB layout clearance for the increased 3.00mm seated height. Confirm that the nonstandard 6.00mm x 6.00mm footprint matches your design. Validate that the improved electrical characteristics do not introduce unintended circuit behavior in your specific application topology.
