ELC-09D272F Equivalent & Substitute Parts

Part Overview

The ELC-09D272F is a 2.7 mH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 160 mA with a DC resistance of 6.1 Ohm. This through-hole radial component operates at a test frequency of 10 kHz and is packaged in a vertical cylinder configuration with a 0.374" diameter and 0.350" maximum seated height.

The ELC-09D272F is classified as obsolete. Equivalent substitute parts are necessary to maintain design continuity and ensure component availability for production, repair, and maintenance applications where this inductor specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELC-09D272F are identified based on the following critical parameters that determine functional equivalence:

Core Substitution Criteria:

• Inductance value: 2.7 mH (±10% tolerance maintained)
• Current rating: 160 mA minimum
• Mounting type: Through hole
• Package configuration: Radial, vertical cylinder
• Shielding type: Unshielded
• RoHS compliance: ROHS3 Compliant

The AIUR-10-272K from Abracon LLC meets these substitution criteria. While the DC resistance differs (7.97 Ohm Max versus 6.1 Ohm), both values fall within acceptable operating parameters for this inductor category. The substitute uses a drum core ferrite construction compared to the original wirewound design, but maintains identical electrical ratings and mechanical compatibility for through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-10-272K is an active production component from Abracon LLC and serves as a direct functional substitute for the obsolete ELC-09D272F. Both components are ROHS3 compliant and carry MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

The substitute component features a smaller physical footprint (0.315" diameter and height versus 0.374" and 0.350" respectively), which provides a space advantage in PCB layouts. The DC resistance differential of 1.87 Ohm (7.97 Ohm Max versus 6.1 Ohm) is within acceptable tolerance for inductor substitution in this category and does not compromise circuit performance at the specified 160 mA current rating.

The AIUR-10-272K's active product status ensures long-term availability and supply chain continuity, eliminating obsolescence risk associated with the original ELC-09D272F component.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-10-272K be used as a direct replacement for the ELC-09D272F?

A: Yes. Both components share identical inductance (2.7 mH), current rating (160 mA), tolerance (±10%), shielding type (unshielded), and mounting configuration (through-hole radial vertical cylinder). The substitute is physically smaller and features active production status.

Q: What is the significance of the DC resistance difference between the two parts?

A: The ELC-09D272F has 6.1 Ohm DCR while the AIUR-10-272K has 7.97 Ohm Max DCR. This 1.87 Ohm difference is within normal variation for wirewound and drum core inductor designs and does not affect functional equivalence at the specified 160 mA operating current.

Q: Are there any PCB layout considerations when substituting the AIUR-10-272K?

A: The AIUR-10-272K is physically smaller (0.315" diameter and height) compared to the ELC-09D272F (0.374" diameter and 0.350" height). Existing PCB footprints designed for the original component will accommodate the substitute with clearance margin. Verify pad spacing and hole diameter compatibility with your PCB design specifications.

Q: Do both components meet the same regulatory and environmental standards?

A: Yes. Both the ELC-09D272F and AIUR-10-272K are ROHS3 compliant and carry MSL rating 1 (Unlimited), indicating equivalent environmental and moisture sensitivity classifications.

Q: What is the operating temperature range for the substitute component?

A: The AIUR-10-272K operates across -55°C to 85°C. The original ELC-09D272F does not specify an operating temperature range in the provided data.
