ELJ-DA101JF Equivalent & Substitute Parts

Part Overview

The ELJ-DA101JF is a 100 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 70 mA maximum current with 13 Ohm maximum DC resistance in a 1210 (3225 Metric) surface mount package. This part is classified as obsolete, making equivalent substitute components necessary for ongoing production and maintenance applications. Substitute parts must maintain the core electrical specifications: 100 µH inductance at ±5% tolerance, surface mount 1210 package form factor, and compatible current and resistance ratings for direct circuit replacement.

Engineering Selection Recommendations

For Active Production (Recommended Primary Substitutes):

1210R-104J (API Delevan Inc.) is the preferred substitute. It exceeds the original current rating at 120 mA, maintains 13 Ohm maximum DC resistance, and extends the operating temperature range to -55°C ~ 125°C. ROHS3 compliance and active product status support long-term supply continuity.

IMC1210EB101J and IMC1210ER101J (Vishay Dale) provide equivalent performance with 73 mA current rating and ROHS3 compliance. IMC1210ER101J is available in Tape & Reel packaging, suitable for automated assembly. IMC1210BN101J and IMC1210SY101J are available but carry RoHS non-compliance status, limiting use in regulated applications.

B82422T1104J000 (EPCOS - TDK Electronics) meets substitution criteria with 60 mA current rating, 11 Ohm maximum DC resistance, and AEC-Q200 automotive qualification. ROHS3 compliance and active status support production applications.

CM322522-101JL (Bourns Inc.) provides 60 mA current rating with 10 Ohm maximum DC resistance and ROHS3 compliance. Limited inventory (864 pcs) may affect supply availability.

For Current-Limited Applications Only:

NLV32T-101J-EF and NLV32T-101J-EFD (TDK Corporation) are suitable only for circuits requiring maximum 40 mA current. NLV32T-101J-EFD includes AEC-Q200 automotive qualification. NLV32T-101J-PF carries "Not For New Designs" status and should be avoided for new development.

Compliance Considerations:

All recommended direct substitutes maintain MSL 1 (Unlimited) moisture sensitivity. ROHS3-compliant parts are required for regulated markets. AEC-Q200 qualification (B82422T1104J000, NLV32T-101J-EFD) is necessary for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-101J series parts replace ELJ-DA101JF in all applications?

A: No. NLV32T-101J series parts are rated for 40 mA maximum current, compared to the original 70 mA rating. These parts are suitable only for circuits with current requirements not exceeding 40 mA. For applications requiring the full 70 mA capability, use 1210R-104J, IMC1210EB101J, IMC1210ER101J, or B82422T1104J000.

Q: What is the difference between IMC1210EB101J and IMC1210ER101J?

A: Both parts are electrically identical with 100 µH inductance, 73 mA current rating, and 14 Ohm maximum DC resistance. The primary difference is packaging: IMC1210EB101J is supplied in Bulk, while IMC1210ER101J is supplied in Tape & Reel (TR). For automated assembly processes, IMC1210ER101J is the appropriate choice.

Q: Are all substitute parts RoHS compliant?

A: No. IMC1210BN101J and IMC1210SY101J are RoHS non-compliant. All other listed substitutes are ROHS3 compliant. For applications requiring RoHS compliance, select from 1210R-104J, B82422T1104J000, CM322522-101JL, IMC1210EB101J, IMC1210ER101J, or NLV32T-101J series parts.

Q: Does the 1210R-104J operate within the original temperature range?

A: Yes. The 1210R-104J operating range of -55°C ~ 125°C encompasses the original ELJ-DA101JF range of -20°C ~ 85°C. All other direct substitutes also meet or exceed the original temperature specification.

Q: Which substitute has the lowest DC resistance?

A: CM322522-101JL and NLV32T-101J series parts offer 10 Ohm maximum DC resistance, compared to the original 13 Ohm specification. B82422T1104J000 provides 11 Ohm maximum. Lower DC resistance reduces power dissipation in high-current applications.

Q: Is AEC-Q200 qualification required for my application?

A: AEC-Q200 qualification is required only for automotive applications. B82422T1104J000 and NLV32T-101J-EFD carry AEC-Q200 certification. For non-automotive applications, this qualification is not necessary.

Q: Can I use IMC1210SY101J despite its RoHS non-compliance status?

A: IMC1210SY101J is electrically equivalent to IMC1210EB101J and IMC1210ER101J. However, RoHS non-compliance restricts use in regulated markets and applications subject to environmental directives. ROHS3-compliant alternatives are available and recommended.
