TSW-105-08-S-S-RA Equivalent & Substitute Parts

Part Overview

The TSW-105-08-S-S-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable connections. This 5-position connector operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The part maintains active product status with 1157 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or procurement constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-105-08-S-S-RA is determined by strict alignment of the following critical parameters:

• Connector Type: Header configuration
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 5
• Number of Rows: 1
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish - Mating: Gold
• Insulation Material: Polybutylene Terephthalate (PBT)

The 3M 929648-01-05-I meets these core substitution criteria. Both parts share identical pitch, position count, row configuration, mounting orientation, and termination method. Both feature gold-plated mating contacts and PBT insulation. Mechanical and electrical compatibility is established through these aligned parameters, enabling direct substitution in applications where the TSW-105-08-S-S-RA is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-105-08-S-S-RA and 929648-01-05-I maintain active product status with full RoHS compliance and unlimited moisture sensitivity ratings. Both parts satisfy UL94 V-0 flammability requirements and are REACH unaffected.

The TSW-105-08-S-S-RA operates across a wider temperature range (-55°C to 125°C) compared to the 3M substitute (-40°C to 105°C). Applications requiring operation below -40°C or above 105°C must retain the Samtec part.

The 3M 929648-01-05-I features a breakaway connector design and specifies a 2.5A current rating. Contact post finish differs between parts: the Samtec uses tin plating while the 3M uses gold plating. Contact finish thickness on mating surfaces also varies (30.0µin versus 10.0µin). These differences do not preclude substitution in standard board-to-board applications but should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929648-01-05-I directly replace the TSW-105-08-S-S-RA in all applications?

A: Direct substitution is valid for applications operating within -40°C to 105°C. Applications requiring the extended temperature range of the Samtec part (-55°C to 125°C) must use the original TSW-105-08-S-S-RA.

Q: What are the mechanical compatibility considerations?

A: Both parts share identical pitch (0.100"), position count (5), row configuration (1), and right-angle through-hole mounting. Contact length variations (mating: 0.230" vs 0.235"; post: 0.090" vs 0.110") are within typical tolerance ranges for standard board-to-board connectors. Insulation height differs by 0.004" (0.10mm), which is negligible for most PCB layouts.

Q: How do the contact finishes differ?

A: The TSW-105-08-S-S-RA uses gold-plated mating contacts (30.0µin) with tin-plated posts. The 3M 929648-01-05-I uses gold-plated mating contacts (10.0µin) with gold-plated posts. Both configurations provide adequate corrosion resistance for standard applications.

Q: Are both parts RoHS compliant?

A: Yes. The TSW-105-08-S-S-RA is ROHS3 compliant, and the 3M 929648-01-05-I is RoHS compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What is the breakaway feature on the 3M part?

A: The 3M 929648-01-05-I includes a breakaway connector design, allowing individual positions to be separated if required. The Samtec TSW-105-08-S-S-RA does not feature this capability.

Q: Which part should be selected for new designs?

A: Selection depends on application temperature requirements and feature needs. For extended temperature operation (-55°C to 125°C), specify the TSW-105-08-S-S-RA. For standard temperature range applications (-40°C to 105°C) where breakaway functionality may be beneficial, the 3M 929648-01-05-I is suitable.
