Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-112-21-F-S is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (12)
• Mating pitch (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Contact finish specification (Gold mating, Tin post)
• Voltage and temperature ratings
• Compliance certifications (UL94 V-0, ROHS3)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Phosphor Bronze)

The SSQ-112-01-F-S meets all these criteria and is classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-112-21-F-S and SSQ-112-01-F-S are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain considerations rather than technical performance differences.

The SSQ-112-21-F-S has 747 units in current stock, while the SSQ-112-01-F-S has 1136 units available. Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The identical contact geometry, pitch, and voltage ratings ensure direct interchangeability in existing designs without PCB layout or assembly process modifications.

Frequently Asked Questions (FAQ)

Q: Can SSQ-112-01-F-S be used as a direct replacement for SSQ-112-21-F-S?

A: Yes. All electrical and mechanical parameters are identical, including connector type, position count, mating pitch, contact finish specifications, voltage rating, and operating temperature range. No design changes are required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification. Regulatory compliance is equivalent.

Q: What determines substitution eligibility for SSQ-112 series receptacles?

A: Substitution is valid when the following parameters match: 12-position count, 0.100" mating pitch, through-hole mounting, gold mating contact finish, tin post finish, -55°C to 125°C operating range, and UL94 V-0 rating.

Q: Do these connectors have different packaging or handling requirements?

A: Both parts are supplied in bulk packaging. Moisture sensitivity level is not applicable for either part, indicating standard handling procedures are sufficient.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. Both parts are rated for 465VAC and 655VDC, supporting equivalent high-voltage performance in board-to-board and cable connection applications.
