ELL-5PS150M Equivalent & Substitute Parts

Part Overview

The ELL-5PS150M is a 15 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1 A continuous current with 170mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates at 100 kHz inductance test frequency and is packaged in a nonstandard surface mount configuration measuring 5.00mm × 5.00mm × 2.00mm.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELL-5PS150M is based on the following critical parameters:

• Inductance Value: 15 µH (exact match required)
• Shielding Type: Shielded configuration
• Mounting Technology: Surface mount, nonstandard package
• Current Handling: Minimum 1 A continuous rating
• DC Resistance: Lower or equivalent values acceptable for improved performance
• Saturation Current: Minimum 790mA
• Test Frequency: 100 kHz inductance measurement standard

The CDRH4D28CLDNP-150PC from Sumida America Components Inc. qualifies as a direct substitute based on matching inductance, shielding, surface mount configuration, and exceeding current and saturation specifications.

Engineering Selection Recommendations

The CDRH4D28CLDNP-150PC is suitable as a substitute for the obsolete ELL-5PS150M based on the following factors:

• Active Product Status: The Sumida part is actively manufactured and supported, ensuring long-term availability and supply chain stability.
• Electrical Compatibility: Identical inductance value (15 µH) at 100 kHz test frequency with improved DC resistance (93.4mOhm vs. 170mOhm), resulting in lower power dissipation.
• Current Margin: 1.6 A rating exceeds the 1 A requirement of the original design, providing operational headroom.
• Compliance: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating. The Sumida part includes ROHS3 compliance certification.
• Physical Considerations: The Sumida part is slightly smaller in footprint (4.90mm vs. 5.00mm) but taller (3.00mm vs. 2.00mm). PCB layout verification is required to confirm height compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CDRH4D28CLDNP-150PC directly replace the ELL-5PS150M without circuit modifications?

A: Yes, the electrical parameters are compatible. The 15 µH inductance, shielding, and current ratings match or exceed the original specification. However, the increased height (3.00mm vs. 2.00mm) requires verification of available PCB clearance.

Q: What is the impact of the lower DC resistance in the substitute part?

A: The CDRH4D28CLDNP-150PC has 93.4mOhm DCR compared to 170mOhm in the original. This reduces resistive losses and heat generation, improving circuit efficiency. No negative effects are introduced.

Q: Are there tolerance differences between the two parts?

A: The ELL-5PS150M has ±20% tolerance while the CDRH4D28CLDNP-150PC has ±25% tolerance. Both fall within acceptable ranges for typical inductor applications. Circuit designs should account for inductance tolerance as specified in the original design documentation.

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

A: The ELL-5PS150M uses an unspecified core material, while the CDRH4D28CLDNP-150PC uses ferrite. Both are shielded configurations with identical inductance values at 100 kHz, indicating functional equivalence for the specified operating frequency.

Q: Is the packaging difference (Tape & Reel vs. unspecified) relevant?

A: The Sumida part is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly. This is compatible with standard pick-and-place equipment and does not affect component functionality.

Q: What are the operating temperature ranges?

A: The ELL-5PS150M operating temperature is not specified in available documentation. The CDRH4D28CLDNP-150PC operates from -40°C to 105°C, covering standard industrial and commercial temperature ranges. Verify the original design's temperature requirements against this specification.
