ELC-09D152DF Equivalent & Substitute Parts

Part Overview

The ELC-09D152DF is a 1.5 mH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 210 mA with a DC resistance of 2.8 Ohm. This through-hole radial component is designed for general-purpose inductive filtering and energy storage applications. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC-09D152DF is determined by the following critical parameters:

• Inductance Value: Must be 1.5 mH to maintain circuit performance
• Tolerance: ±10% ensures acceptable inductance variation
• Current Rating: Minimum 210 mA to handle circuit current without saturation
• DC Resistance: Acceptable range depends on application thermal and efficiency requirements
• Mounting Type: Through-hole radial configuration required for PCB compatibility
• Package Geometry: Radial, vertical cylinder form factor for mechanical fit
• Compliance: ROHS3 compliance required for regulatory alignment

The AISR-875-152K from Abracon LLC meets the core inductance, tolerance, and mounting requirements while maintaining through-hole radial geometry. Differences in shielding, DCR, and current rating are noted for application-specific evaluation.

Engineering Selection Recommendations

The AISR-875-152K qualifies as a functional substitute based on matching inductance value, tolerance, and through-hole radial mounting configuration. Both components are ROHS3 compliant, supporting regulatory requirements for new and legacy applications.

Key considerations for selection:

• Current Capacity: AISR-875-152K provides 220 mA rating, exceeding the 210 mA requirement of the original part
• DC Resistance: The AISR-875-152K exhibits higher DCR (4.7 Ohm max vs. 2.8 Ohm), resulting in increased power dissipation and heat generation in the component
• Shielding: The substitute introduces shielding, which may affect electromagnetic coupling in circuits designed for unshielded operation
• Physical Dimensions: The substitute is smaller (0.307" vs. 0.374" diameter), potentially improving PCB space utilization but requiring verification of mechanical clearance
• Product Status: AISR-875-152K is active production, ensuring long-term availability and supply chain stability

Frequently Asked Questions (FAQ)

Q: Can the AISR-875-152K directly replace the ELC-09D152DF?

A: The AISR-875-152K matches the core electrical specifications (1.5 mH inductance, ±10% tolerance, through-hole radial mounting). However, differences in DC resistance, shielding, and physical dimensions require circuit-level evaluation before implementation.

Q: What impact does the higher DC resistance of the AISR-875-152K have?

A: The 4.7 Ohm DCR of the substitute versus 2.8 Ohm of the original results in increased resistive losses. In applications where the inductor carries continuous current, this generates additional heat. Thermal performance and power budget must be assessed for the specific application.

Q: Does the shielding on the AISR-875-152K affect compatibility?

A: Shielding reduces electromagnetic radiation and susceptibility to external fields. In circuits designed around an unshielded inductor, the introduction of shielding may alter coupling characteristics with adjacent components. Applications sensitive to magnetic field distribution should be evaluated.

Q: Are the physical dimensions compatible with the original PCB layout?

A: The AISR-875-152K is smaller in both diameter (0.307" vs. 0.374") and height (0.295" vs. 0.350"). While this may improve space utilization, mechanical clearance and lead spacing must be verified against the original PCB design.

Q: Are both parts compliant with current regulatory standards?

A: Yes, both the ELC-09D152DF and AISR-875-152K are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
