ELC-09D152F Equivalent & Substitute Parts

Part Overview

The ELC-09D152F 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 operates at a test frequency of 10 kHz and is housed in a vertical cylinder package measuring 0.374" diameter by 0.350" height.

The ELC-09D152F is classified as obsolete. Locating equivalent or substitute inductors is necessary for applications requiring continued component availability, design updates, or inventory replenishment where original stock is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D152F is determined by the following critical parameters:

Core Electrical Specifications:

• Inductance value: 1.5 mH (with ±10% tolerance allowance)
• Current rating: minimum 210 mA
• DC resistance: acceptable range based on application requirements

Physical & Mechanical Compatibility:

• Mounting type: Through Hole
• Package configuration: Radial, Vertical Cylinder
• Physical dimensions: compatible footprint for PCB placement

Regulatory & Environmental:

• RoHS3 compliance
• MSL rating of 1 or better

The AISR-875-152K from Abracon LLC meets these substitution criteria. While it introduces shielding (versus the unshielded design of the original) and operates at a different test frequency (1 kHz versus 10 kHz), it maintains the same inductance value, exceeds the current rating requirement, and shares identical mounting and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The AISR-875-152K is suitable as a substitute for the ELC-09D152F based on the following factors:

Compliance & Availability: The AISR-875-152K maintains ROHS3 compliance and MSL rating 1, matching the regulatory requirements of the original part. As an active product with 732 units in stock, it provides reliable long-term availability compared to the obsolete ELC-09D152F.

Electrical Performance: Both inductors share the same 1.5 mH inductance value and ±10% tolerance. The AISR-875-152K current rating of 220 mA exceeds the 210 mA requirement of the original design. The increased DC resistance of 4.7 Ohm (versus 2.8 Ohm) must be evaluated within the specific circuit application to determine if the additional power dissipation is acceptable.

Physical Considerations: The AISR-875-152K features a smaller footprint (0.307" diameter, 0.295" height) compared to the ELC-09D152F (0.374" diameter, 0.350" height). Both maintain radial, vertical cylinder package geometry suitable for through-hole PCB mounting. The reduced size may provide layout advantages in space-constrained designs.

Design Differences: The AISR-875-152K incorporates shielding, whereas the ELC-09D152F is unshielded. Shielding reduces electromagnetic interference emission and susceptibility, which may be beneficial in noise-sensitive applications or detrimental if the original unshielded design was intentional for specific circuit behavior.

Frequently Asked Questions (FAQ)

Q: Can the AISR-875-152K directly replace the ELC-09D152F without circuit modifications?

A: Direct replacement is possible if the application tolerates the increased DC resistance (4.7 Ohm versus 2.8 Ohm) and the shielded design. The identical inductance value and superior current rating support functional compatibility. Circuit simulation or testing is appropriate to confirm performance in applications sensitive to resistance changes.

Q: What is the impact of the higher DC resistance in the AISR-875-152K?

A: The 1.9 Ohm increase in DC resistance will result in higher power dissipation at rated current. At 210 mA, the additional dissipation is approximately 0.104 watts. Applications with tight thermal budgets or high-frequency switching should evaluate this parameter.

Q: Does the shielding in the AISR-875-152K affect circuit behavior?

A: Shielding reduces electromagnetic field radiation and external interference coupling. If the original design relied on unshielded operation for specific electromagnetic characteristics, the shielded substitute may alter circuit performance. Applications in electromagnetically noisy environments typically benefit from shielding.

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

A: The AISR-875-152K is smaller (0.307" diameter, 0.295" height) than the ELC-09D152F (0.374" diameter, 0.350" height). Both use radial, vertical cylinder through-hole packages. The smaller footprint allows direct substitution on existing PCBs without layout modification, though the reduced size may require clearance verification around the component.

Q: What is the operating temperature range for each inductor?

A: The ELC-09D152F operating temperature is not specified in available documentation. The AISR-875-152K operates across -55°C to 125°C. Applications requiring operation outside this range should confirm compatibility with the original ELC-09D152F specifications or select an alternative substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELC-09D152F and AISR-875-152K are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity level), meeting current environmental and regulatory requirements.
