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

Part Overview

The SS-103-T-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 mating contacts and tin-plated posts, operating across the temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, ensuring functional interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-103-T-2-N is determined by strict alignment of the following 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 specifications (Gold mating, Tin post)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material (PBT, Glass Filled)
• Compliance certifications (ROHS3, REACH Unaffected)

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

Parameter Comparison

Engineering Selection Recommendations

Both the SS-103-T-2-N and SS-103-T-2 are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, as the SS-103-T-2 currently maintains higher stock levels (1192 pcs vs. 1064 pcs). Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

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

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

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

A: No. The parts have identical 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 standards?

A: Yes. Both SS-103-T-2-N and SS-103-T-2 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.69.4040.

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 there temperature or environmental limitations for these connectors?

A: Both parts operate across -55°C to 125°C. The MSL 1 rating indicates unlimited moisture sensitivity, allowing storage without time-based restrictions under standard conditions.
