PE-54041S Equivalent & Substitute Parts

Part Overview

The PE-54041S is a 25 µH shielded toroidal inductor manufactured by Pulse Electronics, rated for 3 A continuous current with 40 mOhm DC resistance. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across an industrial temperature range of -40°C to 130°C and is packaged in a nonstandard surface mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-54041S is determined by the following critical parameters:

• Inductance Value: 25 µH (±20% tolerance acceptable)
• Current Rating: Minimum 3 A
• DC Resistance: 40 mOhm
• Mounting Type: Surface Mount
• Physical Footprint: Compatible with 0.700" L × 0.670" W dimensions
• Operating Temperature: Minimum -40°C to 125°C range

Two substitute parts meet these criteria with the following considerations:

PE-54041SNL (Pulse Electronics): Direct manufacturer equivalent with identical electrical specifications and shielded construction. Differs only in packaging format (Bulk vs. standard) and product status (Active vs. Obsolete).

SH150S-3.00-25 (Amgis, LLC): Functionally equivalent toroidal inductor with matching inductance, current rating, and DC resistance. Key difference is unshielded construction versus shielded design of the original part. Physical height is slightly increased (0.443" vs. 0.390").

Parameter Comparison

Engineering Selection Recommendations

PE-54041SNL is the primary substitute for PE-54041S applications. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The packaging difference (Bulk format) does not affect functional performance. This substitute is suitable for direct replacement in all applications where the original part was specified.

SH150S-3.00-25 serves as an alternative substitute when shielding requirements are not critical to circuit performance. This part provides equivalent inductance, current handling, and DC resistance characteristics. The unshielded construction may introduce electromagnetic coupling considerations in sensitive applications. The increased seated height (0.443" vs. 0.390") requires verification of available PCB clearance. Operating temperature maximum is reduced to 125°C, which may be limiting in high-temperature environments. This substitute is suitable only when electromagnetic shielding is not a functional requirement.

Frequently Asked Questions (FAQ)

Q: Can PE-54041SNL be used as a direct replacement for PE-54041S?

A: Yes. PE-54041SNL is electrically and mechanically identical to PE-54041S. The only differences are packaging format and product status. Both parts are shielded toroidal inductors with 25 µH inductance, 3 A current rating, and 40 mOhm DC resistance.

Q: What is the primary difference between PE-54041SNL and SH150S-3.00-25?

A: The primary difference is shielding. PE-54041SNL maintains the shielded construction of the original PE-54041S, while SH150S-3.00-25 is unshielded. Both parts share identical inductance, current rating, and DC resistance values. The SH150S-3.00-25 also has a slightly increased seated height (0.443" vs. 0.390").

Q: Is SH150S-3.00-25 suitable for all applications requiring PE-54041S?

A: SH150S-3.00-25 is suitable only for applications where electromagnetic shielding is not required. If the circuit design depends on shielded inductor characteristics to prevent EMI coupling or meet EMC requirements, this substitute is not appropriate. PCB layout must accommodate the increased component height.

Q: What compliance certifications apply to each substitute?

A: PE-54041SNL is ROHS3 compliant with MSL 1 (Unlimited moisture sensitivity). SH150S-3.00-25 is ROHS3 compliant with MSL 2 (1 Year moisture sensitivity). The original PE-54041S is RoHS non-compliant.

Q: Are there physical footprint compatibility concerns?

A: PE-54041SNL has identical footprint dimensions to PE-54041S (0.700" L × 0.670" W). SH150S-3.00-25 has nearly identical length and width (0.701" L × 0.669" W) with negligible difference. However, SH150S-3.00-25 seated height is 0.053" taller, requiring clearance verification on the PCB.
