SNT-100-OR-G Equivalent & Substitute Parts

Part Overview

The SNT-100-OR-G is a 2-position shunt connector manufactured by Samtec Inc., featuring an open top design with 0.100" (2.54mm) pitch and gold-plated contacts. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The orange housing variant is no longer in active production, requiring engineers to evaluate functionally compatible alternatives from current inventory.

Substitute Part Grouping Explanation

Substitute parts for the SNT-100-OR-G are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

Number of positions and grid configuration (2 x 1 x 2)
Connector pitch (0.100" / 2.54mm)
Connector type (Open Top)
Gender (Female Sockets)
Contact finish (Gold plating)
Flammability rating (UL94 V-0)
MSL rating (1 - Unlimited)

Substitute Categories:

Direct Equivalent (SNT-100-BK-G): Identical electrical and mechanical specifications with the same base product number (SNT-100). The only difference is housing color (black vs. orange). This part is currently active in production with higher inventory availability.

Similar Substitute (390088-2): TE Connectivity AMPMODU series connector meeting all core position, pitch, type, and gender requirements. Minor dimensional variance in height (0.247" vs. 0.240") and contact finish thickness (15.0µin vs. 10.0µin) are within acceptable tolerance for shunt connector applications. Voltage rating specification (250VAC) is provided for this variant.

Engineering Selection Recommendations

SNT-100-BK-G (Recommended Primary Substitute): This part is the optimal choice for direct replacement. It maintains identical specifications to the SNT-100-OR-G across all electrical and mechanical parameters, with the exception of housing color. The part is currently in active production status with substantial inventory (6,216 pcs), ensuring supply chain continuity. Both parts share the same base product number (SNT-100) and carry equivalent compliance certifications (ROHS3, UL94 V-0, MSL 1).

390088-2 (Alternative Substitute): This TE Connectivity part provides functional compatibility for applications where housing material flexibility is acceptable. The polyester glass-filled housing meets the same flammability standard (UL94 V-0) as the original. The height variance of 0.007" (0.17mm) and increased contact finish thickness (15.0µin vs. 10.0µin) are within typical tolerance ranges for shunt connector applications. This option is suitable when Samtec inventory is unavailable and cross-manufacturer compatibility is permissible. The specified 250VAC voltage rating provides additional margin for applications with voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can SNT-100-BK-G be used as a direct replacement for SNT-100-OR-G?

A: Yes. The SNT-100-BK-G is functionally equivalent to the SNT-100-OR-G. Both parts share identical electrical specifications (4.3A per contact, gold plating), mechanical dimensions (0.240" height, 0.100" pitch), and compliance ratings (UL94 V-0, ROHS3, MSL 1). The only difference is housing color (black vs. orange).

Q: What are the key differences between SNT-100-BK-G and 390088-2?

A: Both parts meet the core requirements for 2-position, 0.100" pitch, open-top female socket connectors with gold contacts and UL94 V-0 flammability ratings. The 390088-2 differs in: housing material (polyester glass-filled vs. PBT), height (0.247" vs. 0.240"), contact finish thickness (15.0µin vs. 10.0µin), and manufacturer (TE Connectivity vs. Samtec). The 390088-2 includes a specified voltage rating of 250VAC.

Q: Are there packaging considerations when switching between these parts?

A: SNT-100-BK-G is supplied in bulk packaging, matching the substitute list specification. The 390088-2 is also supplied in bulk packaging. Verify packaging requirements for your procurement process, as the original SNT-100-OR-G was supplied with unspecified packaging.

Q: Does the height difference of 0.007" between SNT-100-BK-G and 390088-2 affect PCB layout?

A: The height variance (0.240" vs. 0.247") is minimal and typically accommodated within standard PCB design tolerances for shunt connector applications. Verify clearance in your specific mechanical design if vertical space is constrained.

Q: Are all three parts RoHS compliant?

A: Yes. SNT-100-OR-G and SNT-100-BK-G are ROHS3 compliant. The 390088-2 is RoHS compliant. Both certifications meet current regulatory requirements for electronic components.
