Substitute Part Grouping Explanation

The SH150T-0.38-118 qualifies as a direct substitute for the SWT-0.38-118 based on the following matching electrical and mechanical parameters:

• Inductance value: 118 µH (identical)
• Inductance tolerance: ±20% (identical)
• Current rating: 380 mA (identical)
• DC resistance: 1.2Ω (identical)
• Core material: Iron Powder (identical)
• Shielding configuration: Unshielded (identical)
• Mounting type: Through Hole (identical)
• Operating temperature range: -40°C ~ 125°C (identical)
• Test frequency: 10 kHz (identical)
• RoHS3 compliance: Both parts compliant
• REACH status: Both parts unaffected

The primary differences are packaging format (Tray vs. standard packaging), terminal configuration (Corner Terminals vs. Open), and physical dimensions. These differences do not affect electrical performance or functional compatibility in applications designed for the original part.

Engineering Selection Recommendations

The SH150T-0.38-118 is the appropriate substitute for the obsolete SWT-0.38-118. Selection is based on:

• Active product status: The SH150T-0.38-118 is currently in active production, ensuring long-term availability and supply chain continuity.
• Electrical equivalence: All critical electrical parameters match exactly, including inductance, current rating, DC resistance, and operating temperature range.
• Regulatory compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.
• Physical compatibility: While dimensions differ slightly, both parts are through-hole mounted toroidal inductors with identical terminal configurations suitable for PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the SH150T-0.38-118 be used as a direct replacement for the SWT-0.38-118?

A: Yes. The SH150T-0.38-118 provides electrical equivalence across all specified parameters. The substitute part maintains identical inductance, current rating, DC resistance, and operating temperature specifications. Physical dimensions differ slightly, but both parts are through-hole mounted and compatible with standard PCB layouts designed for 118 µH toroidal inductors.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), packaging format (standard vs. tray), terminal configuration (open vs. corner terminals), and physical dimensions. The SH150T-0.38-118 is slightly larger (11.00mm x 11.20mm vs. 8.60mm x 8.60mm) but electrically identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory status is equivalent.

Q: Why is the SWT-0.38-118 listed as obsolete?

A: The SWT-0.38-118 is no longer in active production. The SH150T-0.38-118 from the same manufacturer represents the current active equivalent for this inductance value and current rating.

Q: Will the larger dimensions of the SH150T-0.38-118 affect PCB layout?

A: PCB layout must accommodate the larger footprint (11.00mm x 11.20mm vs. 8.60mm x 8.60mm). Verify that the mounting area on your PCB provides sufficient space for the substitute part before implementation.
