ELL-VGG100M Equivalent & Substitute Parts

Part Overview

The ELL-VGG100M is a 10 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 730 mA continuous current with 280mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The part is housed in a compact 3.00mm x 3.00mm surface mount package with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-VGG100M is determined by the following critical parameters:

Inductance Value: Must be 10 µH with ±20% tolerance
Current Rating: Minimum 730 mA continuous current capability
DC Resistance: Maximum 280mOhm to maintain circuit performance
Package Footprint: 3.00mm x 3.00mm surface mount compatibility
Shielding: Shielded configuration to prevent electromagnetic interference
Saturation Current: Minimum 800mA to ensure stable operation under transient conditions

All four substitute parts meet these core electrical and mechanical requirements, enabling direct replacement in applications where the ELL-VGG100M was originally specified.

Engineering Selection Recommendations

Primary Recommendation: SRN3015-100M (Bourns Inc.)

The SRN3015-100M is the preferred substitute for the ELL-VGG100M. This part is currently in active production status, ensuring long-term availability and supply chain stability. It exceeds the current rating requirement at 1 A, provides superior DC resistance at 276mOhm Max, and maintains identical package footprint and height specifications. ROHS3 compliance and unlimited moisture sensitivity rating align with the original part specifications.

Secondary Recommendation: CDRH2D18B/HPNP-100MC (Sumida America Components Inc.)

The CDRH2D18B/HPNP-100MC offers active production status with shielded configuration and ferrite core construction. DC resistance at 306mOhm Max remains within acceptable tolerance for most applications. Height at 1.95mm exceeds the original 1.50mm specification and must be verified for PCB clearance constraints.

Alternative: ASPI-0310FS-100M-T2 (Abracon LLC)

The ASPI-0310FS-100M-T2 provides active production status with the lowest seated height at 1.00mm, beneficial for space-constrained designs. However, DC resistance at 350mOhm and saturation current at 600mA represent trade-offs requiring circuit-level evaluation.

Not Recommended for New Designs: NRH3012T100MN (Taiyo Yuden)

The NRH3012T100MN carries "Not For New Designs" status, limiting its suitability for ongoing development despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the SRN3015-100M directly replace the ELL-VGG100M without circuit modifications?

A: Yes. The SRN3015-100M meets all critical electrical parameters: 10 µH inductance, 1 A current rating (exceeding the 730 mA requirement), 276mOhm Max DC resistance (better than 280mOhm), and identical 3.00mm x 3.00mm footprint with 1.50mm height. No circuit modifications are required.

Q: Why does the ASPI-0310FS-100M-T2 have higher DC resistance than the original part?

A: The ASPI-0310FS-100M-T2 uses nickel zinc ferrite core material, which results in 350mOhm DC resistance compared to the original 280mOhm. This 25% increase in resistance may affect power dissipation and thermal performance in current-limited applications. Circuit simulation is recommended for high-current or thermally sensitive designs.

Q: Is the semi-shielded configuration of the SRN3015-100M acceptable for EMI-sensitive applications?

A: The SRN3015-100M provides semi-shielded construction versus the fully shielded original design. For applications requiring maximum EMI suppression, the fully shielded alternatives (CDRH2D18B/HPNP-100MC or ASPI-0310FS-100M-T2) are preferred. Application-specific EMI testing may be necessary to confirm compatibility.

Q: What is the impact of height differences among substitute parts?

A: Height variations range from 1.00mm (ASPI-0310FS-100M-T2) to 1.95mm (CDRH2D18B/HPNP-100MC) compared to the original 1.50mm. PCB layout clearance, component stacking, and conformal coating processes must be evaluated. The SRN3015-100M and NRH3012T100MN maintain the original 1.50mm height, eliminating this consideration.

Q: Are all substitute parts ROHS3 compliant?

A: SRN3015-100M, ASPI-0310FS-100M-T2, and NRH3012T100MN carry explicit ROHS3 compliance certification. CDRH2D18B/HPNP-100MC compliance status is not specified in available documentation and should be confirmed with the supplier.

Q: Which substitute offers the best long-term availability?

A: SRN3015-100M (Bourns Inc.) is the optimal choice for long-term supply assurance, carrying active production status with 5100 pieces currently in stock. CDRH2D18B/HPNP-100MC and ASPI-0310FS-100M-T2 also maintain active status. NRH3012T100MN, marked "Not For New Designs," should be avoided for new projects.
