Key Parameters

Substitute Part Grouping Explanation

The SH150T-1.54-77 qualifies as a direct substitute based on the following critical parameters:

• Inductance Value: 77 µH (identical)
• Inductance Tolerance: ±20% (identical)
• Current Rating: 1.54 A (identical)
• DC Resistance: 200mOhm (identical)
• Core Type: Iron Powder (identical)
• Shielding: Unshielded (identical)
• Operating Temperature: -40°C ~ 125°C (identical)
• Mounting Type: Through Hole (identical)
• Test Frequency: 10 kHz (identical)
• Compliance: ROHS3 Compliant (identical)

Substitution is valid across these parts because all electrical performance parameters and environmental ratings are equivalent. Differences exist only in packaging format (Bulk vs. Tray) and terminal configuration (Radial, Horizontal Open vs. Radial, Horizontal Corner Terminals), which do not affect electrical function.

Parameter Comparison

Engineering Selection Recommendations

Both SWT-1.54-77 and SH150T-1.54-77 are active production parts with identical electrical specifications and full regulatory compliance. Selection between these parts should be based on:

• Packaging Requirements: Choose SWT-1.54-77 for bulk packaging applications; select SH150T-1.54-77 for tray-packaged inventory management.
• Terminal Configuration: SWT-1.54-77 features open radial terminals; SH150T-1.54-77 provides corner terminal configuration. PCB layout and assembly equipment compatibility should determine selection.
• Availability: Both parts maintain active stock levels. SWT-1.54-77 has 1079 units available; SH150T-1.54-77 has 1003 units available.
• Compliance: Both parts meet ROHS3, REACH, and EAR99 requirements with identical HTSUS classification.

Frequently Asked Questions (FAQ)

Q: Can SH150T-1.54-77 replace SWT-1.54-77 in existing designs?

A: Yes. Both parts share identical electrical specifications (77 µH inductance, 1.54 A rating, 200mOhm DCR) and environmental ratings (-40°C to 125°C). Substitution is valid provided PCB layout accommodates the terminal configuration difference (corner terminals vs. open radial terminals).

Q: What is the difference between the packaging formats?

A: SWT-1.54-77 is supplied in bulk packaging; SH150T-1.54-77 is supplied in tray packaging. This affects inventory handling and assembly line integration but does not impact electrical performance.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. SWT-1.54-77 measures 0.591" L x 0.591" W x 0.346" H (15.00mm x 15.00mm x 8.80mm). SH150T-1.54-77 measures 0.614" L x 0.591" W x 0.358" H (15.60mm x 15.00mm x 9.10mm). Verify PCB footprint clearance before substitution.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both SWT-1.54-77 and SH150T-1.54-77 are ROHS3 compliant, REACH unaffected, and classified as EAR99 with identical HTSUS code 8504.50.4000.

Q: What is the inductance tolerance for these parts?

A: Both parts carry ±20% inductance tolerance at 10 kHz test frequency. This tolerance applies equally to SWT-1.54-77 and SH150T-1.54-77.
