ELC11D152F Equivalent & Substitute Parts

Part Overview

The ELC11D152F is a 1.5 mH unshielded drum core wirewound inductor manufactured by Panasonic Electronic Components, rated for 430 mA with 1.7Ohm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. Substitute parts must maintain the same inductance value, core type, and mounting configuration while operating within acceptable parameter tolerances for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC11D152F is determined by the following critical parameters:

• Inductance Value: Must be 1.5 mH with ±10% tolerance
• Core Material: Ferrite drum core construction required
• Shielding Configuration: Unshielded design
• Mounting Interface: Through hole radial lead configuration
• Package Geometry: Radial, vertical cylinder form factor
• Current Rating: Minimum 380 mA acceptable; 430 mA nominal
• DC Resistance: Maximum 3Ohm acceptable; lower values preferred for thermal performance

The substitute part 768772152 (Würth Elektronik WE-TI HV series) meets all primary substitution criteria. While the DC resistance is higher (3Ohm max versus 1.7Ohm) and current rating is lower (380 mA versus 430 mA), these parameters remain within acceptable operational margins for equivalent functionality in most applications. The substitute maintains identical inductance, core type, shielding, and mounting configuration.

Engineering Selection Recommendations

The 768772152 (Würth Elektronik WE-TI HV series) is the qualified substitute for the obsolete ELC11D152F. Selection should be based on the following criteria:

Product Status: The ELC11D152F is obsolete; the substitute is actively manufactured and supported, ensuring long-term availability and supply chain continuity.

Compliance: Both parts are RoHS compliant. The substitute carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Electrical Performance: The substitute maintains identical inductance and tolerance specifications. The higher DC resistance (3Ohm max versus 1.7Ohm) and lower current rating (380 mA versus 430 mA) require circuit-level evaluation to confirm suitability for the specific application current profile.

Physical Compatibility: Both parts use identical mounting types and package configurations, supporting direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 768772152 be used as a direct replacement for the ELC11D152F?

A: The 768772152 is functionally equivalent for applications operating at or below 380 mA. The higher DC resistance (3Ohm max) will result in increased power dissipation compared to the original part. Circuit validation is required if the application operates near the 430 mA current rating of the original part.

Q: What are the key differences between these two inductors?

A: The primary differences are current rating (380 mA versus 430 mA), DC resistance (3Ohm max versus 1.7Ohm), and physical dimensions. Inductance, core type, shielding, and mounting configuration are identical.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant. The substitute carries ROHS3 compliance and REACH unaffected status, meeting current regulatory standards. The original part is RoHS compliant without additional certifications listed.

Q: Will the substitute fit in the same PCB footprint?

A: Both parts use radial, vertical cylinder packages with through-hole mounting. Physical dimensions differ slightly (substitute is smaller: 7.80mm diameter versus 11.50mm), but both are compatible with standard through-hole radial lead footprints. PCB layout verification is recommended.

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

A: The 768772152 operates from -40°C to 125°C. Operating temperature specifications for the original ELC11D152F are not provided in the available data.
