Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELJ-FCR82MF are qualified based on the following electrical and mechanical parameters:

• Inductance value: 820 nH (exact match required)
• Package / Case: 1008 (2520 Metric) (exact match required)
• Shielding type: Unshielded (exact match required)
• Mounting type: Surface Mount (exact match required)
• Current rating: Equal to or greater than 130 mA
• DC resistance: Equal to or less than 1.4Ohm
• Operating temperature range: Must encompass or exceed -20°C ~ 85°C

Both substitute parts meet these criteria with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

NLV25T-R82J-EF is the primary substitute for the ELJ-FCR82MF. This part is manufactured by TDK Corporation with Active product status, ensuring long-term availability and supply chain continuity. It meets all electrical and mechanical compatibility requirements with superior performance characteristics: doubled current rating (260 mA vs. 130 mA), reduced DC resistance (1Ohm vs. 1.4Ohm), and tighter inductance tolerance (±5% vs. ±20%). The part is ROHS3 compliant and REACH affected, meeting current regulatory standards. Packaging is available in Tape & Reel (TR) format.

NLV25T-R82J-PF is a secondary substitute option, also manufactured by TDK Corporation. This part carries a "Not For New Designs" product status, indicating it is available for existing production but not recommended for new circuit designs. It provides identical electrical specifications to NLV25T-R82J-EF with higher inventory availability (35,300 Pcs vs. 2,303 Pcs). Packaging is available in Cut Tape (CT) & Digi-Reel® format. Selection of this part should be limited to legacy system maintenance or where existing design validation has been completed.

Frequently Asked Questions (FAQ)

Q: Can NLV25T-R82J-EF and NLV25T-R82J-PF be used interchangeably with ELJ-FCR82MF?

A: Both TDK parts meet the electrical and mechanical substitution criteria. They share identical inductance (820 nH), package format (1008 / 2520 Metric), and unshielded configuration. Both exceed the current rating and DC resistance specifications of the original part. The primary difference is product status: NLV25T-R82J-EF is Active, while NLV25T-R82J-PF is Not For New Designs.

Q: What are the key performance improvements in the substitute parts?

A: The TDK substitutes provide tighter inductance tolerance (±5% vs. ±20%), higher current rating (260 mA vs. 130 mA), lower DC resistance (1Ohm vs. 1.4Ohm), and extended operating temperature range (-40°C ~ 105°C vs. -20°C ~ 85°C). These improvements reduce circuit losses and expand operational margins.

Q: Are there packaging format differences between the substitute parts?

A: Yes. NLV25T-R82J-EF is supplied in Tape & Reel (TR) format, while NLV25T-R82J-PF is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly equipment compatibility and order quantity requirements.

Q: Which substitute part should be selected for new designs?

A: NLV25T-R82J-EF is the recommended choice for new designs due to its Active product status, ensuring sustained manufacturing support and supply availability. NLV25T-R82J-PF should be reserved for legacy system maintenance only.

Q: Are the substitute parts compliant with current regulatory standards?

A: Both TDK substitute parts are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements. The original Panasonic part does not specify these compliance certifications.
