• Current Rating: 65 mA or higher
• Package: 1210 (3225 Metric) or equivalent footprint
• Shielding: Unshielded
• Operating Temperature: Minimum -20°C to 85°C coverage

Similar Substitutes provide functional equivalence with minor parameter variations:

• Inductance: 68 µH ±5%
• DC Resistance: 9Ohm to 10Ohm Max
• Current Rating: 60 mA or higher
• Package: 1210 (3225 Metric) or compatible footprint
• Shielding: Unshielded or Shielded
• Operating Temperature: Extended range capability

Parameter Comparison

Engineering Selection Recommendations

Preferred Direct Substitutes:

PM1210-680J-RC (Bourns Inc.) and CM322522-680JL (Bourns Inc.) provide the closest electrical match to the ELJ-FA680JF with identical inductance, current rating, and DC resistance specifications. Both are active products with ROHS3 compliance and extended operating temperature ranges. PM1210-680J-RC maintains standard 1210 package geometry for direct PCB footprint compatibility.

Higher Current Capacity Alternatives:

1210R-683J and 1210-683J (API Delevan Inc.) offer increased current rating of 144 mA while maintaining 68 µH inductance and 9Ohm DCR. These parts are suitable for applications requiring higher current headroom. The 1210R-683J variant includes ROHS3 compliance; 1210-683J is RoHS non-compliant.

Extended Temperature Range Options:

B82422T1683J000 (EPCOS - TDK Electronics) provides AEC-Q200 automotive qualification with -55°C to 125°C operating range. Current rating is 60 mA, which is within acceptable tolerance for the original 65 mA specification. Package configuration is 2-SMD, J-Lead with 1210 (3225 Metric) supplier device package.

Shielded Alternatives:

ISC1210EB680J and ISC1210ER680J (Vishay Dale) provide shielded construction with 90 mA current rating and 10Ohm maximum DCR. These are suitable for applications requiring electromagnetic interference mitigation. ISC1210ER680J is supplied in Tape & Reel packaging; ISC1210EB680J is supplied in Bulk.

Frequently Asked Questions (FAQ)

Q: Can PM1210-680J-RC be used as a direct replacement for ELJ-FA680JF?

A: Yes. PM1210-680J-RC matches the critical electrical parameters: 68 µH inductance, 65 mA current rating, and 9Ohm maximum DCR. Both use standard 1210 (3225 Metric) package geometry. PM1210-680J-RC is an active product with extended operating temperature range (-40°C to 125°C) and ROHS3 compliance.

Q: What is the difference between 1210R-683J and 1210-683J?

A: Both parts are manufactured by API Delevan Inc. with identical electrical specifications: 68 µH inductance, 144 mA current rating, and 9Ohm DCR. The primary difference is compliance status: 1210R-683J is ROHS3 compliant; 1210-683J is RoHS non-compliant. Both use standard 1210 (3225 Metric) packaging.

Q: Why do ISC1210EB680J and ISC1210ER680J have higher DCR (10Ohm) than the original part?

A: ISC1210EB680J and ISC1210ER680J feature shielded construction with iron powder core material, which results in 10Ohm maximum DCR compared to 9Ohm for the unshielded original. The 1Ohm difference is within typical engineering tolerance for shielded inductor designs. These parts are suitable only if shielding is required for EMI control.

Q: Is B82422T1683J000 suitable for high-reliability applications?

A: Yes. B82422T1683J000 carries AEC-Q200 automotive qualification, indicating suitability for automotive and high-reliability applications. Operating temperature range is -55°C to 125°C. Current rating is 60 mA, which is 5 mA below the original 65 mA specification but within acceptable margin for most applications.

Q: What packaging options are available for these substitutes?

A: Most substitutes are available in Tape & Reel (TR) packaging for automated assembly. CM322522-680JL uses nonstandard packaging. ISC1210EB680J is supplied in Bulk; ISC1210ER680J is supplied in Tape & Reel. Verify packaging compatibility with your procurement and assembly requirements.

Q: Can shielded inductors (ISC series) be used in place of unshielded inductors?

A: Shielded inductors can be used in unshielded applications, but not vice versa. Shielding reduces electromagnetic radiation and susceptibility to external fields. Use shielded variants only if EMI control is required or if circuit layout permits the slightly larger height profile (2.41mm vs. 2.40mm for the original).
