ELL-5PS100M Equivalent & Substitute Parts

Part Overview

The ELL-5PS100M is a 10 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.1 A continuous current with 120mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates at 100 kHz test frequency and is designed for surface mount applications in nonstandard packaging.

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-5PS100M is determined by the following critical parameters:

Inductance Value: Must be 10 µH ±20% tolerance
Current Rating: Minimum 1.1 A continuous current capability
DC Resistance: Maximum 120mOhm to maintain circuit performance
Shielding Configuration: Shielded design to prevent electromagnetic interference
Mounting Type: Surface mount compatibility required
Test Frequency: 100 kHz inductance measurement standard

Two substitute parts meet these criteria: B82462A4103M000 and CDRH4D16FB/NP-100MC. Both maintain the 10 µH inductance specification, exceed the current rating requirement, and are classified as active products with current manufacturing availability.

Engineering Selection Recommendations

CDRH4D16FB/NP-100MC is the primary substitute for the ELL-5PS100M. This part maintains shielded configuration matching the original design, delivers superior current rating (1.2 A vs. 1.1 A), and provides lower DC resistance (118mOhm Max vs. 120mOhm). The component is ROHS3 compliant, active in production, and offers the smallest footprint (4.00mm x 4.00mm x 1.80mm max height), enabling space-constrained applications. Operating temperature range of -40°C to 105°C covers standard industrial and commercial environments.

B82462A4103M000 serves as a secondary substitute with higher current capacity (1.15 A) and superior saturation current (1.8 A), suitable for applications requiring extended thermal margin. However, this part features unshielded construction, which may introduce electromagnetic interference in sensitive circuits. The larger footprint (6.00mm x 6.00mm x 3.00mm max height) and extended operating temperature range (-55°C to 150°C) position this part for high-reliability and extreme-temperature applications. ROHS3 compliance and AEC-Q200 automotive qualification are provided.

Frequently Asked Questions (FAQ)

Q: Can B82462A4103M000 replace ELL-5PS100M in all applications?

A: B82462A4103M000 meets inductance, current rating, and DC resistance specifications. However, the unshielded design differs from the original shielded configuration. Applications sensitive to electromagnetic interference may require circuit-level evaluation before substitution.

Q: What is the impact of DC resistance differences between substitutes?

A: ELL-5PS100M specifies 120mOhm; B82462A4103M000 is 140mOhm Max; CDRH4D16FB/NP-100MC is 118mOhm Max. Higher DC resistance increases power dissipation and heat generation. CDRH4D16FB/NP-100MC provides the lowest resistance, minimizing thermal effects. B82462A4103M000's higher resistance may require thermal analysis in current-limited designs.

Q: Are physical dimensions interchangeable?

A: No. ELL-5PS100M is 5.00mm x 5.00mm x 2.00mm. CDRH4D16FB/NP-100MC is 4.00mm x 4.00mm x 1.80mm (smaller, suitable for compact layouts). B82462A4103M000 is 6.00mm x 6.00mm x 3.00mm (larger, may require PCB redesign). Verify footprint compatibility before selection.

Q: What compliance certifications apply to substitutes?

A: Both CDRH4D16FB/NP-100MC and B82462A4103M000 are ROHS3 compliant. B82462A4103M000 carries AEC-Q200 automotive qualification. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original part.

Q: Which substitute is recommended for new designs?

A: CDRH4D16FB/NP-100MC is recommended for new designs. It maintains shielded construction, provides superior electrical performance (lower DCR, higher current rating), offers the smallest footprint, and is actively manufactured with ROHS3 compliance.
