SS-109-T-2 Equivalent & Substitute Parts

Part Overview

The SS-109-T-2 is a 9-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 for reliable solder termination. The product is currently active and widely used in standard rectangular connector applications requiring push-pull fastening.

Substitute parts are identified when equivalent connectors share the same critical functional parameters: connector type, contact configuration, pitch, mounting method, and termination style. Alternative sources ensure supply chain flexibility and component availability.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 310-93-109-41-001000 (Mill-Max Manufacturing Corp.) qualifies as an equivalent based on the following matching parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 9 (all positions loaded)
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Style: Board to Board
• Contact Finish - Mating: Gold
• Operating Temperature Range: -55°C ~ 125°C
• Contact Material: Beryllium Copper
• Number of Rows: 1

These parameters define the functional interchangeability of the connector in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-109-T-2 and 310-93-109-41-001000 are active products with identical RoHS3 compliance and REACH unaffected status. Both connectors meet the same regulatory and environmental standards applicable to rectangular connectors in this category.

The Mill-Max 310-93-109-41-001000 substitute provides additional specifications including UL94 V-0 material flammability rating and defined current/voltage ratings (3A, 100V/150VDC), which may be relevant for applications requiring explicit electrical performance documentation. The insulation material differs (PCT/Polyester vs. PBT/Glass Filled) and insulation height is slightly increased (0.110" vs. 0.100"), with thicker post plating (200.0µin vs. unspecified).

Selection between these parts should be based on specific application requirements, supply availability, and any design specifications that reference material composition or electrical ratings.

Frequently Asked Questions (FAQ)

Q: What makes the Mill-Max 310-93-109-41-001000 a valid substitute for the Samtec SS-109-T-2?

A: Both connectors share identical core functional parameters: 9-position receptacle configuration, 0.100" (2.54mm) pitch, through-hole solder termination, push-pull fastening, and board-to-board style. Both operate across -55°C to 125°C and feature beryllium copper contacts with gold mating surfaces.

Q: Are there differences in mechanical dimensions between these parts?

A: The insulation height differs slightly: SS-109-T-2 is 0.100" (2.54mm) while 310-93-109-41-001000 is 0.110" (2.79mm). Contact length and pitch remain identical. Verify PCB layout clearances if space is constrained.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference in insulation material?

A: The SS-109-T-2 uses polybutylene terephthalate (PBT) with glass filler, while the 310-93-109-41-001000 uses polycyclohexylenedimethylene terephthalate (PCT) with polyester. Both materials are suitable for standard rectangular connector applications.

Q: Does the Mill-Max part provide electrical ratings?

A: Yes. The 310-93-109-41-001000 specifies 3A current rating and 100V/150VDC voltage rating. The SS-109-T-2 does not provide these specifications in the available data.

Q: Can these connectors be used interchangeably in existing designs?

A: Functional interchangeability is supported by matching pitch, position count, mounting type, and termination method. Verify that the slight increase in insulation height (0.010") does not conflict with PCB layout or mating component clearances.
