TSW-107-08-S-D Equivalent & Substitute Parts

Part Overview

The TSW-107-08-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 14-position, 2-row connector with 0.100" (2.54mm) pitch provides board-to-board or cable interconnection in unshrouded configuration. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-107-08-S-D is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (14 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Shrouding configuration (Unshrouded)

The 3M 929665-02-07-I meets these core substitution criteria. Both connectors share identical position count, pitch spacing, mounting configuration, and termination method, enabling direct functional replacement in board-level applications.

Parameter Comparison

Engineering Selection Recommendations

The 3M 929665-02-07-I serves as a direct functional substitute for the discontinued TSW-107-08-S-D. Both connectors maintain identical electrical and mechanical interface specifications for 14-position, 2-row, 2.54mm pitch applications.

The 929665-02-07-I offers the advantage of active product status with significantly higher inventory availability (2417 units versus 804 units). Both parts meet UL94 V-0 flammability requirements and RoHS compliance standards.

Minor dimensional variations exist in contact lengths (mating contact: 0.005" difference; post contact: 0.010" difference; overall length: 0.015" difference). These variations remain within typical PCB design tolerances for through-hole header applications and do not affect functional compatibility.

The operating temperature range of the 929665-02-07-I (-40°C ~ 105°C) is narrower than the TSW-107-08-S-D (-55°C ~ 125°C). Applications requiring operation below -40°C or above 105°C must retain the original Samtec part or identify alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929665-02-07-I directly replace the TSW-107-08-S-D in existing designs?

A: Yes, for applications within the 3M part's operating temperature range (-40°C ~ 105°C). The connectors share identical pitch, position count, row configuration, and mounting method. PCB footprints designed for the TSW-107-08-S-D accommodate the 929665-02-07-I without modification.

Q: What are the key differences between these two connectors?

A: Primary differences include contact material (Phosphor Bronze versus Copper Alloy), post finish (Tin versus Gold), insulation material composition (PBT only versus PBT with glass-filled polyester), and operating temperature range. Contact length dimensions vary by 0.005" to 0.015" across mating, post, and overall measurements.

Q: Are there compatibility concerns with the contact finish differences?

A: The TSW-107-08-S-D uses tin-plated posts; the 929665-02-07-I uses gold-plated posts. Both finishes are standard for solder termination. Gold plating on the 929665-02-07-I provides enhanced corrosion resistance. Solder joint formation and reliability are not compromised by this substitution.

Q: What is the impact of the narrower operating temperature range on the 3M part?

A: The 929665-02-07-I operates from -40°C to 105°C, compared to the TSW-107-08-S-D range of -55°C to 125°C. Applications requiring operation outside the 3M part's range must use the original Samtec connector or identify alternative solutions rated for the required temperature extremes.

Q: How do the insulation materials compare?

A: The TSW-107-08-S-D uses polybutylene terephthalate (PBT). The 929665-02-07-I uses PBT combined with glass-filled polyester, providing enhanced mechanical and thermal properties. Both materials meet UL94 V-0 flammability standards.

Q: Is the 929665-02-07-I available in sufficient quantity?

A: Yes. The 929665-02-07-I maintains active product status with 2417 units in stock, compared to 804 units of the discontinued TSW-107-08-S-D. This availability advantage supports production continuity and supply chain reliability.
