Substitute Part Grouping Explanation

Substitution eligibility for the SSK-136-S-G is determined by the following critical parameters:

Number of Positions: Must be 36
Pitch - Mating: Must be 0.100" (2.54mm)
Connector Type: Must be Receptacle
Mounting Type: Must be Through Hole
Termination: Must be Solder
Fastening Type: Must be Push-Pull

Engineering Selection Recommendations

All three substitute parts—SLW-136-01-G-S, SLW-136-01-S-S, and CES-136-01-S-S—are active products manufactured by Samtec Inc. and meet ROHS3 compliance requirements. Selection among these alternatives should be based on the following factors:

SLW-136-01-G-S: Features forked contact type with gold post finish and 20.0µin (0.51µm) mating finish thickness. Insulation height of 0.180" (4.57mm) and contact post length of 0.115" (2.92mm) differ from the original SSK-136-S-G. Mated stacking height is 6.09mm.

SLW-136-01-S-S: Features forked contact type with tin post finish and 30.0µin (0.76µm) mating finish thickness. Insulation height of 0.180" (4.57mm) and contact post length of 0.115" (2.92mm) differ from the original SSK-136-S-G. Mated stacking height is 6.09mm.

CES-136-01-S-S: Features female socket contact type matching the original SSK-136-S-G, with tin post finish and 30.0µin (0.76µm) mating finish thickness. Insulation height of 0.200" (5.08mm) and contact post length of 0.128" (3.25mm) differ from the original. Material flammability rating is UL94 V-0. Insulation material is polybutylene terephthalate (PBT).

Frequently Asked Questions (FAQ)

Q: Can SLW series connectors with forked contacts replace the SSK-136-S-G female socket connector?

A: SLW-136-01-G-S and SLW-136-01-S-S feature forked contact geometry rather than female socket contacts. While they maintain the same 36-position, 0.100" pitch, through-hole solder configuration with push-pull fastening and gold mating finish, the contact type difference requires design validation to confirm mating compatibility with the corresponding plug connector.

Q: What is the difference between SLW-136-01-G-S and SLW-136-01-S-S?

A: Both are SLW series forked-contact receptacles with identical mechanical dimensions and mating pitch. The primary difference is the post finish: SLW-136-01-G-S has gold post finish with 20.0µin (0.51µm) mating thickness, while SLW-136-01-S-S has tin post finish with 30.0µin (0.76µm) mating thickness.

Q: Why does CES-136-01-S-S have a different insulation height than the original SSK-136-S-G?

A: CES-136-01-S-S has an insulation height of 0.200" (5.08mm) compared to the SSK-136-S-G at 0.175" (4.45mm). This dimensional difference is a characteristic of the CES series design and must be evaluated for PCB layout and mechanical clearance compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts—SLW-136-01-G-S, SLW-136-01-S-S, and CES-136-01-S-S—are ROHS3 compliant and meet the same regulatory requirements as the original SSK-136-S-G.

Q: What is the contact post length difference between the original and substitute parts?

A: The SSK-136-S-G has a contact post length of 0.138" (4.60mm). SLW series substitutes have 0.115" (2.92mm), while CES-136-01-S-S has 0.128" (3.25mm). These variations affect solder joint depth and PCB pad design and must be evaluated for your specific application.
