Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-116-21-S-T is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle
• Number of Positions: 48
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 3
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Operating Temperature Range: -55°C ~ 125°C
• Voltage Rating: 465VAC, 655VDC
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The SSQ-116-01-S-T qualifies as a direct substitute based on identical alignment across all critical electrical and mechanical parameters within the SSQ series.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-116-21-S-T and SSQ-116-01-S-T maintain Active product status within the Samtec SSQ series. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical differentiation. Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting equivalent regulatory requirements. The SSQ-116-01-S-T currently maintains higher inventory levels (1192 pcs vs. 1101 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)
