ELL-VEG100M Equivalent & Substitute Parts

Part Overview

The ELL-VEG100M is a 10 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 600 mA continuous current with 480mOhm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. Substitute parts must maintain the same inductance value, shielding characteristics, and current handling capability within specified tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-VEG100M is determined by the following critical parameters:

• Inductance Value: Must be 10 µH at 100 kHz test frequency
• Tolerance: ±20% specification must be maintained
• Current Rating: Minimum 600 mA continuous current capability
• DC Resistance: Must not exceed 480mOhm to preserve circuit performance
• Shielding: Shielded construction required
• Package Footprint: 3.00mm x 3.00mm surface mount with 1.00mm maximum height
• Compliance: ROHS3 compliant, MSL 1 rating

Two substitute parts meet these criteria with acceptable parameter variations within the defined tolerance window.

Engineering Selection Recommendations

LMLP0303M100CTAR (KYOCERA AVX) is the primary substitute for new production applications. This part maintains active product status with full manufacturer support, meets all electrical specifications within tolerance, and provides superior DC resistance (450mOhm vs. 480mOhm). The current rating of 510 mA is within acceptable range for applications designed for 600 mA operation, provided circuit margin analysis confirms adequacy. Operating temperature range of -40°C to 125°C exceeds typical industrial requirements.

NRH3010T100MN (Taiyo Yuden) serves as a secondary substitute with higher current capability (620 mA) and lower DC resistance (420mOhm Max), offering improved performance margin. However, this part carries "Not For New Designs" status, limiting its use to legacy system support and existing inventory replacement only. The self-resonant frequency specification of 34 MHz provides additional design reference data.

For obsolescence mitigation, LMLP0303M100CTAR is the recommended primary selection due to active product status and long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can LMLP0303M100CTAR replace ELL-VEG100M in all applications?

A: LMLP0303M100CTAR meets all critical electrical parameters: 10 µH inductance, ±20% tolerance, shielded construction, and identical 3.00mm x 3.00mm x 1.00mm footprint. The 510 mA current rating is lower than the original 600 mA specification. Substitution is valid only when circuit design margin permits operation at the reduced current rating. DC resistance of 450mOhm is superior to the original 480mOhm, providing improved performance.

Q: What is the difference between the two substitute parts?

A: Both substitutes maintain 10 µH inductance and identical package dimensions. NRH3010T100MN provides higher current capability (620 mA vs. 510 mA) and lower DC resistance (420mOhm vs. 450mOhm). However, NRH3010T100MN is classified as "Not For New Designs," restricting its use to legacy applications. LMLP0303M100CTAR carries active product status with ongoing manufacturer support.

Q: Are there packaging differences between these parts?

A: All three parts use identical surface mount packaging: 3.00mm x 3.00mm footprint with 1.00mm maximum seated height. LMLP0303M100CTAR is supplied in Tape & Reel format, while NRH3010T100MN is available in Cut Tape and Digi-Reel formats. Both are compatible with standard pick-and-place assembly equipment.

Q: Do these substitutes meet compliance requirements?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. LMLP0303M100CTAR and NRH3010T100MN maintain identical compliance certifications to the original ELL-VEG100M, ensuring regulatory compatibility in existing designs.

Q: What is the saturation current specification and why does it matter?

A: Saturation current (Isat) indicates the current level at which inductance begins to degrade. ELL-VEG100M specifies 520 mA Isat, LMLP0303M100CTAR specifies 500 mA, and NRH3010T100MN specifies 600 mA. For applications operating near maximum current ratings, NRH3010T100MN provides greater saturation margin, while LMLP0303M100CTAR requires verification that circuit peak currents remain below 500 mA.
