Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSQ-104-01-S-P are identified based on strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle, 4-position, forked contact design
• Pitch & Spacing: 0.100" (2.54mm) mating pitch, single row
• Mounting & Termination: Through-hole solder termination
• Electrical Ratings: 465VAC / 655VDC voltage rating
• Environmental Specifications: -55°C to 125°C operating temperature range, UL94 V-0 flammability rating
• Contact Materials & Finishes: Phosphor bronze contacts with gold mating finish (30.0µin) and tin post finish
• Insulation: Liquid Crystal Polymer (LCP) with black color, 0.335" (8.51mm) height
• Compliance: ROHS3 compliant, EAR99 classification

The substitute parts SSQ-104-01-S-S and SSQ-104-21-S-S maintain identical electrical and mechanical specifications across all critical parameters, differing only in internal design variants within the SSQ series that do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SSQ-104-01-S-P, SSQ-104-01-S-S, and SSQ-104-21-S-S—are functionally equivalent for rectangular connector applications requiring 4-position, 0.100" pitch through-hole receptacle connectors. Selection among these parts may be based on:

• Inventory Availability: SSQ-104-01-S-S has the highest stock level (1554 units), followed by SSQ-104-01-S-P (839 units) and SSQ-104-21-S-S (649 units).
• Compliance Status: All parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.
• Supply Chain Continuity: Any of the three parts can be substituted without design modification, provided PCB footprint and connector orientation accommodate the specific variant.

Frequently Asked Questions (FAQ)

Q: Can SSQ-104-01-S-S be used as a direct replacement for SSQ-104-01-S-P?

A: Yes. Both parts share identical electrical ratings (465VAC / 655VDC), mechanical dimensions (4-position, 0.100" pitch, through-hole), contact materials (phosphor bronze with gold/tin finish), and environmental specifications (-55°C to 125°C, UL94 V-0). The parts are functionally interchangeable.

Q: What is the difference between SSQ-104-01-S-P and SSQ-104-21-S-S?

A: Both parts maintain identical electrical and mechanical specifications. The alphanumeric suffix variation (01 vs. 21) indicates internal design variants within the SSQ series that do not affect functional performance or compatibility. Substitution is valid for equivalent applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. SSQ-104-01-S-P, SSQ-104-01-S-S, and SSQ-104-21-S-S are all ROHS3 compliant, meeting EU directive requirements for restricted substances.

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

A: All three parts operate across -55°C to 125°C, suitable for industrial, automotive, and commercial temperature environments.

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

A: Yes. All parts are rated for 465VAC and 655VDC, supporting both AC and DC high-voltage circuit configurations within the specified voltage limits.

Q: What contact finish is used for mating surfaces?

A: All parts feature gold-plated mating contacts with 30.0µin (0.76µm) thickness, providing corrosion resistance and reliable electrical contact. Post terminations use tin finish for solder compatibility.
