Key Parameters

Substitute Part Grouping Explanation

The SH150S-1.87-53 qualifies as a direct substitute based on matching electrical specifications: identical inductance value of 53 µH at ±20% tolerance, identical current rating of 1.87 A, and identical DC resistance of 130mOhm. Both parts utilize iron powder core material in unshielded toroidal configuration and maintain the same operating temperature range of -40°C to 125°C. Both are surface mount components with ROHS3 compliance and REACH unaffected status. Substitution is valid where mechanical envelope differences are accommodated by the application design.

Parameter Comparison

Engineering Selection Recommendations

Both the SWS-1.87-53 and SH150S-1.87-53 are active production components from Amgis, LLC with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific mechanical constraints. The SWS-1.87-53 features a smaller footprint with maximum seated height of 0.325" (8.25mm) and MSL rating of 1 (unlimited moisture exposure tolerance). The SH150S-1.87-53 has a slightly larger envelope with maximum seated height of 0.388" (9.85mm) and MSL rating of 2 (1-year moisture exposure tolerance). Both parts deliver identical electrical performance across the specified inductance, current, and resistance parameters.

Frequently Asked Questions (FAQ)

Q: Can SH150S-1.87-53 replace SWS-1.87-53 in all applications? A: Electrical substitution is valid due to matching inductance (53 µH), current rating (1.87 A), and DC resistance (130mOhm). Mechanical compatibility must be verified, as the SH150S-1.87-53 has a larger footprint: 0.614" length versus 0.591" and 0.388" maximum height versus 0.325".

Q: What are the key differences between these parts? A: The primary differences are physical dimensions and moisture sensitivity rating. The SWS-1.87-53 offers a more compact profile with MSL 1 rating (unlimited moisture tolerance). The SH150S-1.87-53 has slightly larger length and height dimensions with MSL 2 rating (1-year moisture tolerance).

Q: Are both parts suitable for the same temperature range? A: Yes. Both parts operate across -40°C to 125°C and maintain identical electrical specifications across this range.

Q: What is the significance of the MSL rating difference? A: MSL 1 (SWS-1.87-53) allows unlimited exposure to moisture without special handling. MSL 2 (SH150S-1.87-53) requires controlled storage conditions and has a 1-year shelf life from the date of manufacture.

Q: Are both parts RoHS and REACH compliant? A: Yes. Both the SWS-1.87-53 and SH150S-1.87-53 are ROHS3 compliant and REACH unaffected.
