ELJ-RE15NJF2 Equivalent & Substitute Parts

Part Overview

The ELJ-RE15NJF2 is a 15 nH unshielded multilayer inductor manufactured by Panasonic Electronic Components, rated for 350 mA with a maximum DC resistance of 410mOhm in a 0603 (1608 Metric) surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates across a temperature range of -40°C to 85°C and exhibits a self-resonant frequency of 2.5 GHz.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELJ-RE15NJF2 are qualified based on the following electrical and mechanical parameters:

• Inductance Value: 15 nH (exact match required)
• Tolerance: ±5% (matching specification)
• Package / Case: 0603 (1608 Metric) (identical footprint)
• Mounting Type: Surface Mount (identical assembly method)
• Current Rating: Minimum 300 mA (acceptable if ≥ original 350 mA or application permits lower rating)
• DC Resistance: Maximum 450 mOhm (acceptable if ≤ original 410 mOhm or application permits higher resistance)
• Operating Temperature Range: Must encompass or exceed -40°C ~ 85°C
• Shielding: Unshielded (matching electromagnetic profile)

Two substitute parts meet these criteria: B82496C3150J000 (EPCOS - TDK Electronics) and CI160808-15NJ (Bourns Inc.).

Parameter Comparison

Engineering Selection Recommendations

B82496C3150J000 is the primary substitute candidate. This part is manufactured by EPCOS - TDK Electronics with Active product status, ensuring long-term availability and supply chain stability. It exceeds the original current rating (420 mA vs. 350 mA), provides superior DC resistance (400 mOhm vs. 410 mOhm), and demonstrates higher Q factor (14 vs. 10 at 100 MHz). The extended operating temperature range (-55°C ~ 150°C) provides additional thermal margin. ROHS3 compliance satisfies modern regulatory requirements. The higher self-resonant frequency (4.5 GHz) may offer improved performance in high-frequency applications.

CI160808-15NJ is a secondary substitute option. Manufactured by Bourns Inc., this part carries a "Not For New Designs" status, limiting its suitability for new product development. The current rating (300 mA) falls below the original specification, making it unsuitable for applications requiring the full 350 mA rating. However, it remains compatible for legacy designs with reduced current requirements. ROHS3 compliance is present. The lower self-resonant frequency (1.35 GHz) may introduce limitations in high-frequency circuit applications.

Frequently Asked Questions (FAQ)

Q: Can B82496C3150J000 be used as a direct replacement for ELJ-RE15NJF2?

A: Yes. Both parts share identical inductance (15 nH), tolerance (±5%), package (0603), and mounting type (Surface Mount). The B82496C3150J000 meets or exceeds all critical electrical parameters and operates across a wider temperature range.

Q: What is the difference between the two substitute parts?

A: B82496C3150J000 has higher current rating (420 mA vs. 300 mA), lower DC resistance (400 mOhm vs. 450 mOhm), and higher self-resonant frequency (4.5 GHz vs. 1.35 GHz). B82496C3150J000 carries Active status; CI160808-15NJ is marked "Not For New Designs."

Q: Is CI160808-15NJ suitable for my application?

A: CI160808-15NJ is compatible only if your circuit operates at or below 300 mA. If your design requires the full 350 mA rating, B82496C3150J000 is the appropriate choice.

Q: Do the substitute parts fit the same PCB footprint?

A: Yes. All three parts use the 0603 (1608 Metric) package with identical land pattern dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm).

Q: What are the RoHS compliance differences?

A: The original ELJ-RE15NJF2 is RoHS non-compliant. Both substitutes (B82496C3150J000 and CI160808-15NJ) are ROHS3 compliant, meeting current environmental regulations.

Q: Which substitute should I select for new designs?

A: B82496C3150J000 is the recommended choice for new designs due to its Active product status, superior electrical performance, and full compliance with modern standards.
