ELC-15E332L Equivalent & Substitute Parts

Part Overview

The ELC-15E332L is a 3.3 mH shielded drum core wirewound inductor manufactured by Panasonic Electronic Components. This through-hole component is rated for 530 mA continuous current with a DC resistance of 1.6 Ohm and operates at 10 kHz test frequency. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-15E332L is determined by the following critical parameters:

• Inductance value: 3.3 mH (primary electrical specification)
• Core material: Ferrite shielded construction
• Mounting configuration: Through-hole radial vertical cylinder
• Current handling capability: Minimum 450 mA (substitute threshold)
• DC resistance: Maximum 3.31 Ohm (acceptable variance for equivalent function)
• Regulatory compliance: ROHS3 certification required

The RCP1317NP-332L meets these substitution criteria with matching inductance, ferrite core construction, shielded design, and through-hole mounting. Variations in current rating (450 mA vs. 530 mA), DC resistance (3.31 Ohm vs. 1.6 Ohm), and physical dimensions are within acceptable parameters for equivalent circuit performance in applications where the ELC-15E332L is specified.

Parameter Comparison

Engineering Selection Recommendations

The RCP1317NP-332L is an active production equivalent for the obsolete ELC-15E332L. Both components meet ROHS3 compliance requirements and share identical inductance specifications with ferrite shielded core construction and through-hole mounting.

Selection of the RCP1317NP-332L requires verification that the application tolerates the following parameter differences:

• Current rating reduction from 530 mA to 450 mA
• DC resistance increase from 1.6 Ohm to 3.31 Ohm maximum
• Inductance tolerance widening from ±10% to ±15%
• Physical size reduction (14.60mm diameter vs. 16.00mm, 17.50mm height vs. 23.00mm)

The substitute part is suitable for applications where circuit current does not exceed 450 mA and where increased DC resistance does not compromise circuit performance or thermal management requirements.

Frequently Asked Questions (FAQ)

Q: Can the RCP1317NP-332L directly replace the ELC-15E332L in all applications?

A: Direct replacement is possible only when the application current requirement does not exceed 450 mA and the increased DC resistance (3.31 Ohm vs. 1.6 Ohm) does not negatively impact circuit performance or power dissipation budgets.

Q: What is the impact of the wider inductance tolerance on circuit performance?

A: The RCP1317NP-332L tolerance of ±15% compared to the ELC-15E332L tolerance of ±10% results in a wider inductance variation range. Applications sensitive to inductance accuracy must evaluate whether this tolerance range remains acceptable for the intended circuit function.

Q: Are the physical dimension differences significant for PCB layout?

A: The RCP1317NP-332L is smaller (14.60mm diameter, 17.50mm height) than the ELC-15E332L (16.00mm diameter, 23.00mm height). PCB footprints and component spacing must be verified for compatibility with the substitute part's reduced dimensions.

Q: What is the saturation current specification for the ELC-15E332L?

A: The saturation current (Isat) is not specified in the ELC-15E332L datasheet. The RCP1317NP-332L specifies 510 mA saturation current for reference.

Q: Are both parts RoHS compliant?

A: Yes, both the ELC-15E332L and RCP1317NP-332L are ROHS3 compliant with moisture sensitivity level 1 (unlimited).
