Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-112-23-S-D is determined by equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 24 positions
• Pitch & Row Spacing: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Contact Finish: Gold mating surface with tin post finish
• Electrical Ratings: 465VAC / 655VDC voltage specification
• Temperature Range: -55°C to 125°C operating envelope
• Compliance: UL94 V-0 flammability and ROHS3 certification

The identified substitute SSQ-112-03-S-D maintains all critical electrical and mechanical parameters, enabling direct functional replacement in board-to-board and cable connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-112-23-S-D and SSQ-112-03-S-D are active production parts from Samtec Inc. with equivalent electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements. The SSQ-112-03-S-D carries MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, providing additional compliance documentation for regulated applications. Both parts meet UL94 V-0 flammability requirements and ROHS3 compliance standards, suitable for industrial and commercial connector applications operating within the specified -55°C to 125°C temperature range and 465VAC / 655VDC voltage envelope.

Frequently Asked Questions (FAQ)

Q: Can SSQ-112-03-S-D directly replace SSQ-112-23-S-D in existing designs?

A: Yes. Both connectors share identical electrical and mechanical parameters including 24-position configuration, 0.100" pitch, through-hole solder termination, gold mating contacts, and operating specifications. Direct substitution is supported without design modification.

Q: What are the key compatibility criteria for these rectangular connectors?

A: Compatibility is determined by position count (24), mating pitch (0.100"), row configuration (2 rows with 0.100" spacing), mounting method (through-hole), contact finish (gold mating / tin post), and electrical ratings (465VAC / 655VDC). All parameters match between the main part and substitute.

Q: Are there differences in moisture sensitivity or compliance between these parts?

A: The SSQ-112-03-S-D specifies MSL Level 1 (Unlimited) and REACH Unaffected status, while the SSQ-112-23-S-D lists MSL as Not Applicable. Both maintain ROHS3 compliance and UL94 V-0 flammability certification. For applications requiring explicit moisture sensitivity documentation, the SSQ-112-03-S-D provides additional compliance detail.

Q: What is the operating temperature range for both connectors?

A: Both SSQ-112-23-S-D and SSQ-112-03-S-D operate across -55°C to 125°C, supporting industrial and extended temperature applications.

Q: Are these connectors suitable for high-voltage applications?

A: Yes. Both connectors are rated for 465VAC and 655VDC, meeting requirements for industrial power distribution and control circuit applications within these voltage specifications.
