Key Parameters

Substitute Part Grouping Explanation

The SH150S-3.00-38 qualifies as a direct substitute for the SWS-3.00-38 based on the following alignment of critical electrical and mechanical parameters:

Electrical Equivalence:

• Inductance: 38 µH (identical)
• Inductance Tolerance: ±20% (identical)
• Current Rating: 3 A (identical)
• DC Resistance: 50mOhm (identical)
• Core Material: Iron Powder (identical)
• Shielding Configuration: Unshielded (identical)
• Operating Temperature Range: -40°C ~ 125°C (identical)

Mechanical Compatibility:

• Mounting Type: Surface Mount (identical)
• Package Classification: Nonstandard (identical)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (identical)

Dimensional Variance: Physical dimensions differ slightly between the two parts. The SH150S-3.00-38 exhibits length and height variations within the nonstandard package category, which may require PCB layout verification for mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

Both the SWS-3.00-38 and SH150S-3.00-38 maintain Active product status from Amgis, LLC with identical electrical specifications and full regulatory compliance under ROHS3 and REACH standards. Selection between these parts should be based on:

Availability and Lead Time: The SH150S-3.00-38 maintains higher inventory levels (3484 Pcs vs. 911 Pcs), providing improved supply chain flexibility.

Moisture Handling Requirements: The SWS-3.00-38 carries MSL 1 (Unlimited) rating, while the SH150S-3.00-38 carries MSL 2 (1 Year). Applications with extended storage or high-humidity environments may require the SWS-3.00-38.

Physical Footprint: The SH150S-3.00-38 provides reduced seated height (10.85mm vs. 12.85mm) with slightly increased length (24.30mm vs. 24.60mm). PCB layout constraints should determine suitability.

Frequently Asked Questions (FAQ)

Q: Are the SWS-3.00-38 and SH150S-3.00-38 electrically interchangeable?

A: Yes. Both parts deliver identical inductance (38 µH), current rating (3 A), DC resistance (50mOhm), core material (Iron Powder), and operating temperature range (-40°C ~ 125°C). Electrical performance is equivalent.

Q: What are the physical differences between these parts?

A: The SH150S-3.00-38 is 0.80mm longer (24.30mm vs. 24.60mm) and 2.00mm shorter in seated height (10.85mm vs. 12.85mm). Width remains identical at 24.60mm. PCB layout verification is required before substitution.

Q: Do moisture sensitivity differences affect substitution?

A: The SWS-3.00-38 carries MSL 1 (Unlimited) while the SH150S-3.00-38 carries MSL 2 (1 Year). For applications with extended storage periods or high-humidity exposure, the SWS-3.00-38 provides superior moisture tolerance. Standard manufacturing environments typically accommodate MSL 2 components.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the SWS-3.00-38 and SH150S-3.00-38 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Which part should be selected for new designs?

A: Both parts are Active status. Selection should prioritize availability, physical footprint constraints, and moisture sensitivity requirements specific to the application environment.
