ELL-4LG100MA Equivalent & Substitute Parts

Part Overview

The ELL-4LG100MA is a 10 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 950 mA continuous current with 200mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part is mounted as a surface mount device in a nonstandard 3.80mm x 3.80mm package with 1.80mm maximum seated height.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-4LG100MA are selected based on the following critical parameters:

• Inductance Value: All substitutes must maintain 10 µH ±20% inductance at 100 kHz test frequency
• Current Rating: Substitute parts must support the application's current requirements; acceptable substitutes range from 770 mA to 1.5 A
• DC Resistance: Acceptable range is 100 mOhm to 240 mOhm, with lower values preferred for reduced power dissipation
• Shielding: All substitutes maintain shielded or semi-shielded construction to control electromagnetic interference
• Package Compatibility: Surface mount nonstandard packages with dimensions approximately 4.00mm x 4.00mm footprint and heights between 1.20mm and 3.00mm
• Compliance: All substitutes are ROHS3 compliant with MSL 1 rating and active product status

Parameter Comparison

Engineering Selection Recommendations

ASPI-4030S-100M-T (Abracon LLC) is the primary substitute for applications requiring maximum current headroom. This part provides 1.5 A current rating with the lowest DC resistance at 100 mOhm, reducing thermal dissipation. The drum core wirewound construction with nickel zinc ferrite core material offers superior performance characteristics. Active product status ensures long-term availability. Height of 3.00mm requires PCB layout verification for space-constrained applications.

LMLP04B4M100CTAS (KYOCERA AVX) is the optimal substitute for direct form-fit-function replacement. Current rating of 840 mA and DC resistance of 180 mOhm closely match the original specification. Height of 1.80mm matches the ELL-4LG100MA exactly, minimizing PCB redesign. Active product status and ferrite core construction provide stable long-term performance.

SRN4018-100M (Bourns Inc.) serves as an alternative for applications where semi-shielded construction is acceptable. Current rating of 1.3 A provides adequate margin above the 950 mA requirement. DC resistance of 180 mOhm and 1.80mm height match critical mechanical parameters. Active product status and established supply chain support production continuity.

LMLP04A4M100CTAS (KYOCERA AVX) is suitable only for applications with current requirements below 770 mA. DC resistance of 240 mOhm is the highest among substitutes, resulting in increased power dissipation. Minimum height of 1.20mm offers space savings in height-constrained designs. Active product status ensures availability.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, meeting environmental and moisture sensitivity requirements of the original component.

Frequently Asked Questions (FAQ)

Q: Can LMLP04A4M100CTAS replace ELL-4LG100MA in all applications?

A: No. LMLP04A4M100CTAS has a current rating of 770 mA, which is below the original 950 mA specification. Use this substitute only when application current requirements are confirmed below 770 mA.

Q: What is the primary difference between ASPI-4030S-100M-T and other substitutes?

A: ASPI-4030S-100M-T offers the highest current rating at 1.5 A and lowest DC resistance at 100 mOhm. However, its 3.00mm height exceeds the original 1.80mm, requiring PCB layout verification.

Q: Is SRN4018-100M semi-shielded construction acceptable as a replacement?

A: SRN4018-100M semi-shielded construction differs from the fully shielded ELL-4LG100MA. Electromagnetic interference performance may differ. Verify EMI/RFI requirements before substitution.

Q: Do all substitutes maintain the same package footprint?

A: All substitutes use approximately 4.00mm x 4.00mm footprint, slightly larger than the original 3.80mm x 3.80mm. PCB layout modifications may be required. Height varies from 1.20mm to 3.00mm depending on part selection.

Q: Are all substitutes available in the same packaging format?

A: ELL-4LG100MA packaging information is not specified in available data. ASPI-4030S-100M-T, LMLP04B4M100CTAS, and LMLP04A4M100CTAS are supplied in Tape & Reel (TR) format. SRN4018-100M is available in Cut Tape (CT) & Digi-Reel format. Verify packaging requirements for production processes.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. SRN4018-100M and ASPI-4030S-100M-T carry REACH Unaffected status where specified.
