ELJ-RE2N2DF2 Equivalent & Substitute Parts

Part Overview

The ELJ-RE2N2DF2 is a 2.2 nH unshielded multilayer inductor manufactured by Panasonic Electronic Components, rated for 500 mA with a maximum DC resistance of 90mOhm in a 0603 (1608 Metric) surface mount package. This part is classified as obsolete, necessitating identification of equivalent substitute components for new designs and ongoing production support. Substitute parts must maintain electrical compatibility across inductance value, current rating, and package specifications while meeting modern compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELJ-RE2N2DF2 is determined by the following critical parameters:

• Inductance Value: Must be 2.2 nH with tolerance ±0.3nH or tighter
• Package / Case: Must be 0603 (1608 Metric) surface mount
• Shielding Configuration: Must be unshielded
• Current Rating: Must meet or exceed 500 mA minimum requirement
• DC Resistance: Lower DCR values are acceptable; higher values require application verification
• Operating Temperature: Must support minimum -40°C ~ 85°C range

Three substitute parts meet these criteria: B82496C3229A000 and B82496C3229Z000 from EPCOS - TDK Electronics, and CI160808-2N2D from Bourns Inc. All three maintain the 2.2 nH inductance specification, 0603 package format, and unshielded configuration. The EPCOS variants offer superior current ratings (1.5 A) and lower DCR (35mOhm), while the Bourns part provides a multilayer construction similar to the original.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes: B82496C3229A000 and B82496C3229Z000 (EPCOS - TDK Electronics)

Both EPCOS variants are active products with ROHS3 compliance and AEC-Q200 ratings, providing superior electrical performance and extended temperature operating range (-55°C ~ 150°C). The B82496C3229Z000 offers tighter inductance tolerance (±0.2nH versus ±0.3nH), while both provide 1.5 A current rating and 35mOhm DCR, exceeding the original part specifications. These parts are recommended for new designs requiring long-term supply assurance and regulatory compliance.

Alternative Substitute: CI160808-2N2D (Bourns Inc.)

The CI160808-2N2D maintains multilayer construction identical to the original ELJ-RE2N2DF2 and carries ROHS3 compliance. However, this part is classified as "Not For New Designs" and features a reduced current rating of 300 mA, which falls below the original 500 mA specification. The elevated DCR of 160mOhm Max also exceeds the original 90mOhm specification. This part is suitable only for legacy system maintenance where the 300 mA current rating is sufficient for the application.

Frequently Asked Questions (FAQ)

Q: Can B82496C3229A000 and B82496C3229Z000 be used interchangeably?

A: Yes. Both parts share identical electrical specifications (2.2 nH, 1.5 A, 35mOhm DCR, 0603 package) and are functionally equivalent. The B82496C3229Z000 provides tighter inductance tolerance (±0.2nH) compared to B82496C3229A000 (±0.3nH). Selection between them depends on tolerance requirements and supplier availability.

Q: Why does CI160808-2N2D have a lower current rating than the original part?

A: The CI160808-2N2D is a different design from Bourns with multilayer construction optimized for different electrical characteristics. Its 300 mA rating is insufficient for applications requiring the original 500 mA specification. This part is suitable only for applications with lower current demands.

Q: Are all substitute parts compatible with the original PCB layout?

A: Yes. All substitute parts maintain the 0603 (1608 Metric) package format with identical footprint dimensions (0.063" L x 0.031" W). Height variations are minimal (0.031" to 0.037" seated height) and do not affect PCB assembly compatibility.

Q: What compliance advantages do the EPCOS parts offer?

A: The B82496C3229A000 and B82496C3229Z000 are ROHS3 compliant and carry AEC-Q200 automotive qualification ratings. The original ELJ-RE2N2DF2 is RoHS non-compliant. For applications requiring regulatory compliance or automotive-grade reliability, the EPCOS variants are the appropriate choice.

Q: Can the higher current rating of EPCOS parts cause issues in the original circuit?

A: No. Higher current ratings indicate greater design margin and do not negatively impact circuit performance. The 1.5 A rating of EPCOS parts provides additional headroom for the original 500 mA application requirement.
