Key Parameters

Substitute Part Grouping Explanation

The SQT-102-01-FM-D has one identified substitute: SQT-102-01-F-D. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Pitch and row spacing (0.079" / 2.00mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish specification (Gold mating surface)
• Current rating (5.1A per contact)
• Operating temperature range (-55°C ~ 125°C)
• Flammability compliance (UL94 V-0)
• RoHS compliance status

Both parts belong to the SQT series and share identical base product number SQT-102, confirming mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations
