Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELJ-RE2N7DF2 is determined by the following critical parameters:

• Inductance Value: 2.7 nH (tolerance ±0.3nH acceptable)
• Package / Case: 0603 (1608 Metric) surface mount
• Shielding Configuration: Unshielded
• Current Rating: Minimum 500 mA
• DC Resistance: Maximum 100mOhm
• Mounting Type: Surface Mount

The substitute parts B82496C3279Z000, B82496C3279A000, and CI160808-2N7D meet the core inductance and package requirements. However, variations in current rating, DC resistance, and operating temperature range create distinct substitution scenarios.

Parameter Comparison

Engineering Selection Recommendations

B82496C3279Z000 and B82496C3279A000 (EPCOS - TDK Electronics): These parts are preferred substitutes for the ELJ-RE2N7DF2. Both are active products with ROHS3 compliance and AEC-Q200 automotive qualification. They provide superior current rating (1.4 A versus 500 mA), lower DC resistance (40mOhm versus 100mOhm), and extended operating temperature range (-55°C ~ 150°C). The B82496C3279Z000 offers tighter inductance tolerance (±0.2nH). Both parts use drum core wirewound construction with ceramic cores and are available in high inventory quantities.

CI160808-2N7D (Bourns Inc.): This part is a secondary substitute option. While it maintains the same 2.7 nH inductance and 0603 package, it has a lower current rating (300 mA) and higher DC resistance (200mOhm) compared to the original ELJ-RE2N7DF2. The product status is "Not For New Designs," limiting its suitability for new development. It is ROHS3 compliant but lacks AEC-Q200 certification.

For new designs, B82496C3279Z000 or B82496C3279A000 are the recommended selections. For legacy production support where the original part is unavailable, CI160808-2N7D may be considered only if circuit requirements permit the reduced current rating and increased DC resistance.

Frequently Asked Questions (FAQ)

Q: Can B82496C3279Z000 and B82496C3279A000 be used interchangeably with ELJ-RE2N7DF2?

A: Yes, both parts are direct substitutes. They share identical inductance (2.7 nH), package (0603), and shielding configuration. The EPCOS parts exceed the original specifications in current rating and DC resistance performance, making them suitable for applications requiring the ELJ-RE2N7DF2.

Q: What is the difference between B82496C3279Z000 and B82496C3279A000?

A: Both parts are functionally equivalent with identical electrical ratings. The primary difference is inductance tolerance: B82496C3279Z000 offers ±0.2nH tolerance versus ±0.3nH for B82496C3279A000. Selection depends on circuit tolerance requirements.

Q: Why does CI160808-2N7D have a lower current rating than the original part?

A: The CI160808-2N7D uses multilayer construction with ceramic core material, resulting in a 300 mA current rating. This is lower than the ELJ-RE2N7DF2 (500 mA). Applications requiring the full 500 mA rating should use the EPCOS alternatives.

Q: Are all substitute parts RoHS compliant?

A: B82496C3279Z000, B82496C3279A000, and CI160808-2N7D are all ROHS3 compliant. The original ELJ-RE2N7DF2 is RoHS non-compliant, making the substitutes suitable for RoHS-regulated applications.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard. B82496C3279Z000 and B82496C3279A000 carry this certification, indicating suitability for automotive and high-reliability applications. CI160808-2N7D does not have this certification.

Q: Can I use CI160808-2N7D if my circuit only requires 300 mA?

A: Yes, if your circuit current requirement does not exceed 300 mA, CI160808-2N7D is a valid substitute. However, the higher DC resistance (200mOhm versus 100mOhm) will result in increased power dissipation and should be evaluated for thermal performance.

Q: What is the impact of different core materials on performance?

A: The ELJ-RE2N7DF2 uses non-magnetic core material, while substitutes use ceramic cores. This affects Q factor and self-resonant frequency but does not impact the 2.7 nH inductance value or basic substitution compatibility for standard RF and signal integrity applications.
