TSW-110-14-S-D Equivalent & Substitute Parts

Part Overview

The TSW-110-14-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 20-position, 2-row connector operates across an extended temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, making it suitable for standard industrial and commercial applications requiring reliable interconnection.

Substitute parts become necessary when addressing supply chain constraints, design revisions requiring alternative manufacturers, or specific performance requirements that alternative designs may better accommodate.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-110-14-S-D is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Connector Type: Header (with or without breakaway feature)
• Contact Type: Male Pin
• Number of Positions: 20
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Material: PBT or equivalent polymer
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant or RoHS Compliant

Secondary Compatibility Parameters:

• Contact Finish - Mating: Gold (required for electrical compatibility)
• Contact Finish - Post: Tin or Gold (acceptable variations)
• Operating Temperature Range: Must encompass or match the -55°C to 125°C specification
• MSL Rating: 1 (Unlimited) preferred

The substitute parts listed below meet these criteria and are therefore electrically and mechanically compatible with the TSW-110-14-S-D for standard interconnection applications.

Engineering Selection Recommendations

929715-01-10-I (3M) - Primary Substitute

The 3M 929715-01-10-I is the closest electrical and mechanical equivalent to the TSW-110-14-S-D. Both connectors share identical position count (20), row configuration (2), pitch spacing (0.100"), and mounting methodology (through-hole solder). Contact geometry, overall length, and flammability ratings align within acceptable engineering tolerances. Both maintain Active product status and RoHS compliance.

The 929715-01-10-I operates across -40°C to 105°C, which is narrower than the TSW-110-14-S-D's -55°C to 125°C range. This difference is significant only for applications requiring the extended low-temperature performance below -40°C or sustained operation above 105°C. The 3M part features gold-plated posts compared to tin plating on the Samtec part, providing enhanced corrosion resistance in demanding environments.

5-146253-5 (TE Connectivity) - Limited Substitution

The TE Connectivity 5-146253-5 is a 10-position variant within the same connector family. This part is not a direct substitute for the TSW-110-14-S-D due to the reduced position count (10 versus 20). However, it shares the same pitch spacing, mounting type, and contact technology. This part is suitable only for applications where a 10-position configuration meets the design requirement or where the connector can be used in parallel or cascaded arrangements.

The 5-146253-5 employs Liquid Crystal Polymer (LCP) insulation instead of PBT, offering superior dimensional stability and lower moisture absorption. Operating temperature range extends to -65°C, exceeding the Samtec part's lower limit. Current rating of 3A is specified, compared to unspecified ratings on the main part.

Selection Criteria Summary

For direct replacement requiring identical position count and performance envelope: 929715-01-10-I

For applications with reduced position requirements or requiring extended low-temperature performance: 5-146253-5

For applications requiring operation below -40°C or above 105°C: TSW-110-14-S-D remains the only option among these three parts.

Frequently Asked Questions (FAQ)

Q: Can the 929715-01-10-I directly replace the TSW-110-14-S-D in all applications?

A: The 929715-01-10-I is mechanically and electrically compatible for most standard applications. The primary limitation is operating temperature range. If your application requires sustained operation below -40°C or above 105°C, the TSW-110-14-S-D is required. For applications within -40°C to 105°C, the 3M part is a suitable substitute.

Q: Why is the 5-146253-5 listed as a substitute if it has only 10 positions?

A: The 5-146253-5 is listed because it shares the same connector family, pitch spacing, and contact technology. It is a substitute only for applications where a 10-position configuration is acceptable or where multiple connectors can be used. It is not a direct one-to-one replacement for the 20-position TSW-110-14-S-D.

Q: What are the key differences in contact finish between these parts?

A: The TSW-110-14-S-D uses gold-plated mating contacts (30.0µin) with tin-plated posts. The 929715-01-10-I uses gold-plated mating contacts (10.0µin) with gold-plated posts. The 5-146253-5 uses gold-plated mating contacts (30.0µin) with tin-plated posts. All three meet UL94 V-0 flammability requirements. Gold plating thickness differences may affect contact resistance and corrosion resistance in specific environments.

Q: Are all three parts RoHS compliant?

A: Yes. The TSW-110-14-S-D and 5-146253-5 are ROHS3 compliant. The 929715-01-10-I is RoHS compliant. All three parts meet current environmental regulations for lead-free and restricted substance requirements.

Q: What is the significance of the insulation material differences?

A: The TSW-110-14-S-D uses Polybutylene Terephthalate (PBT). The 929715-01-10-I uses PBT with polyester and glass filling for enhanced mechanical properties. The 5-146253-5 uses Liquid Crystal Polymer (LCP), which offers superior dimensional stability and lower moisture absorption. For standard applications, these differences are not critical. LCP is preferred for high-precision applications or environments with significant humidity variation.

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

A: The 929715-01-10-I can be used interchangeably with the TSW-110-14-S-D in PCB designs, as both share identical pitch spacing (0.100"), row configuration (2 rows), and overall contact length within acceptable tolerances. The 5-146253-5 cannot be used interchangeably due to its 10-position configuration; PCB footprints designed for 20 positions will not accommodate this part without design modification.

Q: What is the MSL rating and why does it matter?

A: All three parts carry MSL 1 (Unlimited) rating, indicating they have unlimited shelf life and require no special moisture control during storage or handling. This simplifies inventory management and reduces the risk of moisture-induced failures during assembly.
