SS-105-T-2 Equivalent & Substitute Parts

Part Overview

The SS-105-T-2 is a 5-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 stocked with 1,089 units available.

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 may be necessary due to inventory availability, lead time requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. part number 310-93-105-41-001000 qualifies as a direct substitute for the SS-105-T-2 based on the following matching parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 5
• Pitch: 0.100" (2.54mm)
• Style: Board to board
• Mounting type: Through hole
• Termination: Solder
• Fastening type: Push-pull
• Contact finish (mating): Gold
• Operating temperature range: -55°C ~ 125°C
• RoHS compliance: ROHS3 Compliant

These parameters define the functional interchangeability of rectangular connectors in this category. Variations in secondary parameters such as insulation material, contact finish thickness on posts, and flammability ratings do not affect the core substitution relationship.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-105-T-2 and 310-93-105-41-001000 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component applications. The Mill-Max part offers higher current rating (3A) and specified voltage ratings (100V, 150VDC) compared to the Samtec part, which does not specify these parameters. The Mill-Max connector also includes UL94 V-0 flammability rating, providing additional material certification.

Selection between these parts should be based on design requirements, inventory availability, and supply chain lead times. Both connectors are functionally equivalent for board-to-board 5-position 0.100" pitch applications with through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Are the SS-105-T-2 and 310-93-105-41-001000 mechanically compatible?

A: Yes. Both connectors share identical pitch (0.100"), number of positions (5), mounting type (through hole), and fastening mechanism (push-pull), ensuring mechanical compatibility in board-to-board applications.

Q: What are the critical parameters for substitution in this connector category?

A: Connector type, contact type, number of positions, pitch, mounting type, termination method, and fastening type must match exactly. These parameters determine functional interchangeability.

Q: Does the Mill-Max part have additional electrical specifications?

A: The 310-93-105-41-001000 specifies current rating (3A) and voltage ratings (100V, 150VDC), while the SS-105-T-2 does not provide these parameters in the available data.

Q: Are there differences in insulation material between these parts?

A: Yes. The SS-105-T-2 uses Polybutylene Terephthalate (PBT) glass-filled insulation, while the 310-93-105-41-001000 uses Polycyclohexylenedimethylene Terephthalate (PCT) polyester insulation. Both materials are suitable for the specified operating temperature range.

Q: Do both parts meet current compliance standards?

A: Yes. Both the SS-105-T-2 and 310-93-105-41-001000 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference in contact finish thickness on the posts?

A: The SS-105-T-2 does not specify post contact finish thickness. The 310-93-105-41-001000 specifies 200.0µin (5.08µm) tin-lead plating on posts, compared to tin plating on the Samtec part.
