Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-129-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 29 positions
• Pitch & Mounting: 0.100" (2.54mm) mating pitch with through-hole PCB mounting
• Contact & Termination: Forked gold-plated contacts with solder termination
• Electrical Ratings: 465VAC / 655VDC voltage specification
• Temperature Range: -55°C to 125°C operating envelope
• Compliance: ROHS3 compliance and UL94 V-0 flammability rating

The SSQ-129-01-G-S meets all these criteria and is classified as a direct equivalent within the SSQ series.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-129-21-G-S and SSQ-129-01-G-S are active production parts with identical electrical, mechanical, and environmental specifications. Selection between these parts should be based on:

• Inventory Availability: SSQ-129-21-G-S has 1085 units in stock; SSQ-129-01-G-S has 1004 units in stock
• Compliance Requirements: Both parts meet ROHS3 compliance and UL94 V-0 flammability standards
• Supply Chain Continuity: Either part provides equivalent functional performance for board-to-board or cable connector applications

No performance degradation or functional limitation occurs when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can SSQ-129-01-G-S be used as a direct replacement for SSQ-129-21-G-S?

A: Yes. Both parts are 29-position receptacle connectors with identical pitch (0.100"), mounting type (through-hole), contact configuration (forked gold-plated), and electrical ratings (465VAC / 655VDC). All mechanical and environmental specifications are equivalent.

Q: Are there any differences in PCB footprint between these parts?

A: No. Both connectors share the same 0.100" (2.54mm) pitch, insulation height (0.335"), and contact post length (0.104"), resulting in identical PCB footprint requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSQ-129-21-G-S and SSQ-129-01-G-S are ROHS3 compliant and carry UL94 V-0 flammability certification.

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

A: Both parts operate across -55°C to 125°C, supporting applications in industrial and extended temperature environments.

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

A: Yes. Both parts are rated for 465VAC and 655VDC, making them suitable for moderate to high-voltage board-to-board and cable interconnect applications.
