ELJ-PA1R0MF Equivalent & Substitute Parts

Part Overview

The ELJ-PA1R0MF is a 1 µH unshielded drum core wirewound inductor manufactured by Panasonic Electronic Components, rated for 600 mA with a maximum DC resistance of 150 mOhm. This component is packaged in a 1210 (3225 Metric) surface mount form factor and operates across a temperature range of -20°C to 85°C. The part is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELJ-PA1R0MF are selected based on strict electrical and mechanical compatibility criteria. The following parameters must align for direct substitution:

• Inductance value: 1 µH (exact match required)
• Package / Case: 1210 (3225 Metric) (physical compatibility)
• Core type: Ferrite drum core, wirewound (functional equivalence)
• Shielding: Unshielded (electromagnetic behavior consistency)
• Mounting type: Surface mount (assembly compatibility)

Current rating, DC resistance, and operating temperature ranges may vary within acceptable limits depending on circuit requirements. Tolerance specifications and product status should be evaluated against design constraints.

Parameter Comparison

Engineering Selection Recommendations

NLCV32T-1R0M-EF (TDK Corporation) is the primary substitute for the ELJ-PA1R0MF. This part maintains identical inductance and package specifications while offering superior electrical performance with lower DC resistance (78 mOhm vs. 150 mOhm) and higher current rating (1 A vs. 600 mA). The NLCV32T-1R0M-EF carries Active product status and is ROHS3 compliant, supporting long-term design continuity and regulatory compliance.

NLV32T-1R0J-PF (TDK Corporation) is a secondary alternative suitable only for applications where the 400 mA current rating is sufficient. This part exhibits significantly higher DC resistance (700 mOhm) compared to the original specification and carries Not For New Designs status, limiting its applicability to legacy system maintenance only. The tighter tolerance specification (±5%) may provide benefit in precision-critical applications.

Frequently Asked Questions (FAQ)

Q: Can NLCV32T-1R0M-EF directly replace ELJ-PA1R0MF in existing designs?

A: Yes. Both parts share identical inductance (1 µH), package (1210 / 3225 Metric), core material (ferrite), and shielding configuration (unshielded). The NLCV32T-1R0M-EF provides improved electrical characteristics with lower DC resistance and higher current capacity, making it functionally superior for the same footprint.

Q: What are the limitations of NLV32T-1R0J-PF as a substitute?

A: The NLV32T-1R0J-PF has a maximum current rating of 400 mA, which is below the original 600 mA specification. Additionally, its DC resistance of 700 mOhm significantly exceeds the original 150 mOhm maximum, resulting in higher power dissipation. This part is designated Not For New Designs and should only be considered for legacy applications where current requirements do not exceed 400 mA.

Q: Are there temperature range considerations when substituting?

A: The ELJ-PA1R0MF operates from -20°C to 85°C. Both substitute parts (NLCV32T-1R0M-EF and NLV32T-1R0J-PF) support extended temperature ranges of -40°C to 105°C, providing broader operational capability. If the original design operates within the narrower temperature window, both substitutes remain compatible.

Q: What is the significance of product status in selecting a substitute?

A: NLCV32T-1R0M-EF carries Active status, indicating ongoing manufacturing and availability for new designs. NLV32T-1R0J-PF is marked Not For New Designs, meaning the manufacturer does not recommend it for new applications. For new product development, NLCV32T-1R0M-EF is the appropriate choice.

Q: Do the substitute parts meet the same compliance standards?

A: Both substitute parts are ROHS3 compliant. The NLCV32T-1R0M-EF is REACH Unaffected, while NLV32T-1R0J-PF is REACH Affected. Both carry identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications as the original part.
