Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-111-23-S-D is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle)
• Number of positions (22)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish specifications (Gold mating, Tin post)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Voltage rating (465VAC, 655VDC)
• Flammability rating (UL94 V-0)
• RoHS compliance status

The SSQ-111-03-S-D meets all substitution criteria, sharing identical electrical and mechanical specifications with the main part within the SSQ series connector family.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-111-23-S-D and SSQ-111-03-S-D maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical differentiation.

The SSQ-111-23-S-D currently maintains 966 units in stock, while the SSQ-111-03-S-D provides 1,125 units. Both parts share identical specifications across all critical parameters including connector geometry, contact materials, termination methods, and environmental ratings. Component selection should prioritize supply chain continuity and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Are SSQ-111-23-S-D and SSQ-111-03-S-D electrically interchangeable?

A: Yes. Both parts are 22-position receptacle connectors with identical pitch spacing (0.100"), contact finish specifications (gold mating, tin post), voltage ratings (465VAC, 655VDC), and operating temperature ranges (-55°C to 125°C). They share the same base product number (SSQ-111) within the SSQ series.

Q: What determines substitution eligibility for SSQ-111-23-S-D?

A: Substitution is based on matching connector type, position count, pitch spacing, row configuration, mounting method, termination type, fastening mechanism, contact materials and finishes, insulation properties, temperature rating, voltage rating, and compliance certifications. All these parameters must align for functional equivalence.

Q: Can these connectors be used in high-temperature applications?

A: Both parts operate within -55°C to 125°C. Applications requiring operation outside this range require alternative connector specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both SSQ-111-23-S-D and SSQ-111-03-S-D are ROHS3 compliant with UL94 V-0 flammability ratings.

Q: What is the difference between the two part numbers?

A: The SSQ-111-23-S-D and SSQ-111-03-S-D are functionally equivalent. The difference in part number designation reflects internal Samtec product line organization but does not indicate electrical or mechanical differences. Both parts meet identical specifications for 22-position, 0.100" pitch receptacle connectors.

Q: Are these connectors suitable for PCB through-hole mounting?

A: Yes. Both parts feature through-hole solder termination with 0.394" (10.00mm) post length, designed for direct PCB mounting and wave or reflow soldering processes.
