Parameter Comparison

Engineering Selection Recommendations

SH150T-0.30-176 (Amgis, LLC): This substitute maintains identical electrical specifications and operating temperature range. The part is active in production status, ensuring long-term availability. Physical dimensions differ slightly (11.00mm x 11.20mm vs. 8.60mm x 8.60mm), requiring PCB layout verification. Terminal configuration changes from open to corner terminals, necessitating footprint adjustment. Packaging is supplied in trays rather than bulk. ROHS3 and REACH compliance are maintained.

PE-53810NL (Pulse Electronics): This substitute matches all critical electrical parameters and extends the operating temperature range to -40°C to 130°C. The primary distinction is shielded construction versus the unshielded original, which may affect EMI performance in the circuit. Physical dimensions are 10.16mm x 10.16mm with vertical orientation and corner terminals, requiring significant PCB layout changes. Active product status ensures availability. ROHS3 and REACH compliance are maintained.

Frequently Asked Questions (FAQ)

Q: Can SH150T-0.30-176 be used as a direct replacement for SWT-0.30-176?

A: Electrical substitution is valid. All critical parameters—inductance, tolerance, current rating, and DC resistance—are identical. However, physical dimensions and terminal configurations differ, requiring PCB footprint redesign and layout verification before implementation.

Q: What is the primary difference between SH150T-0.30-176 and PE-53810NL?

A: Both maintain identical inductance, current rating, and DC resistance. The key difference is shielding: SH150T-0.30-176 is unshielded (matching the original), while PE-53810NL is shielded. PE-53810NL also offers extended temperature range to 130°C. Physical dimensions and orientations differ between both parts.

Q: Is the shielded PE-53810NL suitable for applications requiring unshielded inductors?

A: Shielded construction does not prevent electrical substitution based on the provided parameters. However, shielding affects electromagnetic field distribution and may alter circuit behavior in sensitive applications. Circuit-level testing is the responsibility of the design engineer.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: Yes. SH150T-0.30-176 and PE-53810NL both maintain ROHS3 compliance and REACH unaffected status, matching the original SWT-0.30-176.

Q: What packaging considerations apply to these substitutes?

A: SWT-0.30-176 uses standard packaging (not specified). SH150T-0.30-176 is supplied in trays. PE-53810NL packaging is not specified. Verify packaging requirements with procurement before ordering.
