Substitute Part Grouping Explanation

Substitute parts for the SSQ-115-01-G-S are qualified based on the following critical parameters that determine functional interchangeability:

Connector Type & Position Count: Both substitute parts are 15-position receptacles, matching the original specification.
Pitch & Mounting: 0.100" (2.54mm) pitch with through-hole solder termination ensures mechanical and electrical compatibility.
Fastening & Contact Configuration: Push-pull fastening and square contact geometry are preserved across all qualified substitutes.
Mating Contact Finish: Gold plating on mating contacts is maintained in both substitute parts.
Insulation Material & Color: Black insulation is consistent; substitute parts use polyester glass-filled insulation versus the original's liquid crystal polymer.
Contact Material: Phosphor bronze contact material is identical across all parts.

The two qualified substitutes are TE Connectivity AMP Connectors parts 1-534237-3 and 6-534237-3, both from the AMPMODU Mod IV series. These parts satisfy the core electrical and mechanical requirements for direct substitution in board-to-board and cable connector applications.

Engineering Selection Recommendations

Both TE Connectivity substitute parts satisfy the core electrical and mechanical requirements for direct substitution with the SSQ-115-01-G-S. Selection between the two substitutes depends on compliance and certification requirements:

6-534237-3 is the preferred substitute when RoHS compliance and UL94 V-0 flammability certification are required. This part maintains full compliance with ROHS3 standards and carries the same UL94 V-0 rating as the original Samtec connector, making it suitable for applications with strict regulatory or safety requirements.

1-534237-3 is an alternative when RoHS compliance is not a design constraint. This part does not carry RoHS certification and lacks specified flammability rating documentation, but remains functionally equivalent for applications without these compliance mandates.

Both substitutes operate across an extended lower temperature range (-65°C versus -55°C minimum), providing enhanced performance in cold environments. The slightly thicker gold plating (30.0µin versus 20.0µin) and longer contact post length (0.115" versus 0.104") on both TE Connectivity parts offer improved contact durability and mating reliability.

Frequently Asked Questions (FAQ)

Q: Can 1-534237-3 or 6-534237-3 be used as direct replacements for SSQ-115-01-G-S in existing designs?

A: Yes, both parts are mechanically and electrically compatible. The 0.100" (2.54mm) pitch, 15-position configuration, through-hole solder termination, and push-pull fastening are identical. Insulation height differences (0.340" versus 0.335") and contact post length variations (0.115" versus 0.104") fall within acceptable tolerances for standard PCB layouts. Verify compliance requirements before final selection.

Q: What are the key differences between the two TE Connectivity substitutes?

A: The primary difference is compliance certification. Part 6-534237-3 is RoHS Compliant with UL94 V-0 flammability rating, while 1-534237-3 is RoHS non-compliant without specified flammability certification. Both parts are functionally identical in electrical performance and mechanical configuration. Contact finish on the post differs (tin-lead versus tin), but this does not affect mating performance.

Q: Are there any temperature rating considerations when substituting?

A: The TE Connectivity substitutes operate from -65°C to 125°C, compared to the original -55°C to 125°C range. This extended lower temperature capability is advantageous and does not create compatibility issues. Applications operating within the original -55°C to 125°C window will function identically with either substitute.

Q: How do packaging differences affect component handling and storage?

A: The original SSQ-115-01-G-S is supplied in bulk packaging, while both TE Connectivity substitutes are supplied in tube packaging. Tube packaging provides improved component protection during storage and handling. Moisture sensitivity level (MSL) for both substitutes is rated 1 (Unlimited), indicating no special moisture control requirements during storage or assembly.

Q: What is the significance of the gold plating thickness difference?

A: The TE Connectivity substitutes feature 30.0µin (0.76µm) gold plating on mating contacts compared to 20.0µin (0.51µm) on the original. Thicker gold plating provides enhanced corrosion resistance and improved contact durability over extended mating cycles. This represents an improvement in contact reliability and longevity.

Q: Are voltage and current ratings equivalent across all three parts?

A: The original SSQ-115-01-G-S specifies 465VAC and 655VDC voltage ratings with no current rating specified. Both TE Connectivity substitutes specify 2A current rating with no voltage rating documented. For applications requiring specific voltage or current verification, consult detailed electrical specifications from each manufacturer to confirm suitability for your circuit requirements.
