ELC-09D151DF Equivalent & Substitute Parts

Part Overview

The ELC-09D151DF is a 150 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 740 mA with a DC resistance of 320mOhm. This through-hole radial component operates at a test frequency of 10 kHz and is packaged in a vertical cylinder configuration with 0.374" diameter and 0.350" maximum seated height.

The product is currently obsolete, making substitute components necessary for new designs, repairs, and ongoing production support. Equivalent parts must maintain the same inductance value, tolerance, mounting type, and package configuration while meeting or exceeding the current rating and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELC-09D151DF is determined by the following critical parameters:

• Inductance Value: Must be 150 µH ±10%
• Current Rating: Substitute must support minimum 740 mA; higher ratings are acceptable
• DC Resistance: Substitute DCR must not exceed the original specification to maintain circuit performance
• Mounting Type: Must be through-hole configuration
• Package Configuration: Must be radial, vertical cylinder format
• Shielding: Unshielded configuration required
• Compliance: ROHS3 compliance mandatory for regulatory alignment

The AIUR-09-151K from Abracon LLC meets these substitution criteria with equivalent inductance, higher current rating capability, and matching package geometry, though with increased DC resistance and different core material composition.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-09-151K is a qualified substitute for the ELC-09D151DF based on the following factors:

Compliance & Availability: The AIUR-09-151K maintains ROHS3 compliance and active product status, ensuring long-term availability and regulatory alignment for new designs and production continuity.

Electrical Equivalence: Both components share identical inductance values (150 µH) and tolerance specifications (±10%), meeting the core functional requirement. The AIUR-09-151K's higher current rating (1 A versus 740 mA) provides additional design margin without compromising circuit operation.

Physical Compatibility: Both components use through-hole radial, vertical cylinder packaging. The AIUR-09-151K exhibits slightly larger diameter (0.394" versus 0.374") and reduced height (0.256" versus 0.350"), requiring PCB layout verification for space-constrained applications.

DC Resistance Consideration: The AIUR-09-151K exhibits higher maximum DC resistance (510mOhm versus 320mOhm). Circuit designs sensitive to resistive losses require evaluation of this parameter increase.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-09-151K directly replace the ELC-09D151DF in existing designs?

A: Direct replacement is possible for applications where the increased DC resistance (510mOhm maximum versus 320mOhm) and slightly larger diameter (0.394" versus 0.374") do not impact circuit performance or PCB layout. Physical fit and electrical loss characteristics must be verified for each application.

Q: What is the significance of the different core materials?

A: The ELC-09D151DF uses unspecified core material, while the AIUR-09-151K uses ferrite drum core construction. Both maintain unshielded configuration and equivalent inductance values. Core material differences do not affect substitution eligibility when inductance and tolerance specifications are met.

Q: Are there any compliance differences between these components?

A: Both components are ROHS3 compliant with MSL rating of 1 (Unlimited). The AIUR-09-151K includes REACH Unaffected status, providing additional regulatory documentation. No compliance barriers exist for substitution.

Q: How does the current rating difference affect substitution?

A: The AIUR-09-151K's higher current rating (1 A versus 740 mA) provides additional thermal margin and is acceptable for applications originally designed for the ELC-09D151DF. The substitute will not degrade performance in circuits operating at or below the original 740 mA specification.

Q: What PCB layout considerations apply to the AIUR-09-151K?

A: The AIUR-09-151K is slightly larger in diameter (0.394" versus 0.374") and shorter in height (0.256" versus 0.350"). PCB footprints designed for the ELC-09D151DF require verification to accommodate the increased diameter. The reduced height may improve clearance in space-constrained designs.
