SS-103-G-2-N Equivalent & Substitute Parts

Part Overview

The SS-103-G-2-N is a 3-position receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated contacts on both mating and post surfaces, solder termination, and push-pull fastening. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when they maintain identical electrical and mechanical specifications across all critical parameters that define connector interchangeability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-103-G-2-N is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (3)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact finish materials and thicknesses (Gold on both mating and post)
• Insulation material (PBT, Glass Filled)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The SS-103-G-2 meets all these criteria and qualifies as a direct substitute for the SS-103-G-2-N.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-103-G-2-N and SS-103-G-2 are active production parts from Samtec Inc. with identical ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating. Selection between these parts should be based on inventory availability and procurement lead times, as they are electrically and mechanically equivalent. The SS-103-G-2 currently maintains higher inventory levels (1981 pcs vs. 752 pcs), which may influence supply chain decisions.

Frequently Asked Questions (FAQ)

Q: Can SS-103-G-2 be used as a direct replacement for SS-103-G-2-N?

A: Yes. Both parts share identical specifications across all critical parameters: connector type, contact configuration, pitch, mounting method, termination type, contact finishes, insulation material, and operating temperature range. They are functionally interchangeable.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. The parts have identical mating pitch (0.100"), insulation height (0.100"), contact length (0.125"), and contact shape (circular). PCB footprints and mating interfaces are identical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both SS-103-G-2-N and SS-103-G-2 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference between these two part numbers?

A: The parts are functionally equivalent. The difference in part numbering reflects internal Samtec designation but does not indicate any electrical or mechanical variation.

Q: Are the contact finishes identical?

A: Yes. Both parts feature 30.0µin (0.76µm) gold plating on mating contacts and 10.0µin (0.25µm) gold plating on post contacts, with beryllium copper base material.
