ELC-09D151F Equivalent & Substitute Parts

Part Overview

The ELC-09D151F is a 150 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 740 mA continuous current with 320mOhm DC resistance. This through-hole radial component operates at 10 kHz test frequency and is housed in a vertical cylinder package measuring 9.50mm diameter by 8.90mm height.

The ELC-09D151F is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this inductor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D151F is determined by the following critical parameters:

• Inductance Value: Must be 150 µH ±10% tolerance
• Current Rating: Must meet or exceed 740 mA
• DC Resistance: Must not exceed 320mOhm to maintain circuit performance
• Mounting Type: Must be through-hole compatible
• Package / Case: Must be radial, vertical cylinder configuration
• Shielding: Unshielded specification
• Regulatory Compliance: ROHS3 compliant

The AIUR-09-151K from Abracon LLC meets these substitution criteria. While it features a drum core ferrite construction versus the original wirewound design, it maintains the required 150 µH inductance, exceeds the current rating at 1 A, and operates within acceptable DC resistance parameters at 510mOhm maximum.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-09-151K is a direct functional substitute for the ELC-09D151F based on the following engineering criteria:

Inductance Compatibility: Both components deliver 150 µH at ±10% tolerance, ensuring equivalent circuit performance in applications designed for the original specification.

Current Capacity: The AIUR-09-151K provides 1 A rating, exceeding the ELC-09D151F requirement of 740 mA, allowing operation with additional design margin.

DC Resistance: The AIUR-09-151K maximum DCR of 510mOhm is higher than the original 320mOhm specification. This parameter difference must be evaluated within the context of the specific application circuit to determine acceptable performance impact.

Physical Compatibility: Both components use radial, vertical cylinder through-hole packages. The AIUR-09-151K is slightly larger in diameter (10.00mm vs. 9.50mm) but shorter in height (6.50mm vs. 8.90mm). PCB layout verification is required to confirm mechanical fit.

Regulatory Status: Both components are ROHS3 compliant. The AIUR-09-151K is active product status, ensuring ongoing availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-09-151K directly replace the ELC-09D151F without circuit modification?

A: The AIUR-09-151K meets the core electrical specifications (inductance, current rating, shielding, and mounting type). However, the increased DC resistance (510mOhm vs. 320mOhm) may affect circuit performance depending on application sensitivity. Circuit analysis is required to confirm acceptable operation.

Q: What is the significance of the different core materials (wirewound vs. drum core ferrite)?

A: The ELC-09D151F uses wirewound construction while the AIUR-09-151K uses drum core ferrite. Both achieve the required 150 µH inductance specification. Core material differences may affect frequency response characteristics and thermal behavior, which should be evaluated for the specific application.

Q: Are there physical fit concerns when substituting the AIUR-09-151K?

A: The AIUR-09-151K has a slightly larger diameter (10.00mm vs. 9.50mm) and shorter height (6.50mm vs. 8.90mm). PCB layout and component spacing must be verified to ensure the substitute component fits within the available board space without interference.

Q: Why is the original ELC-09D151F classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The AIUR-09-151K from Abracon LLC is an active product with confirmed current inventory and ongoing manufacturing support.

Q: What compliance certifications apply to both components?

A: Both the ELC-09D151F and AIUR-09-151K are ROHS3 compliant. The AIUR-09-151K additionally carries REACH Unaffected status. Both components have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited).
