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

Part Overview

The TSW-107-08-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications requiring a 7-position, single-row vertical configuration with 0.100" (2.54mm) pitch. This connector is classified as discontinued at DiGi Electronics, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (7)
• Number of rows (1)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination method (Solder)
• Operating temperature range compatibility
• Flammability rating (UL94 V-0)
• RoHS compliance status

The substitute part 3-644456-7 (TE Connectivity AMP Connectors, MTA-100 series) meets these core substitution criteria, enabling functional equivalence in applications requiring a 7-position, single-row header with standard 2.54mm pitch and through-hole solder termination.

Parameter Comparison

Engineering Selection Recommendations

The 3-644456-7 (TE Connectivity MTA-100 series) serves as a functional equivalent for the discontinued TSW-107-08-S-S. Both connectors maintain identical core specifications: 7-position, single-row, 2.54mm pitch header with through-hole solder termination and UL94 V-0 flammability rating.

Key considerations for selection:

The TSW-107-08-S-S operates across -55°C to 125°C, while the 3-644456-7 operates across -55°C to 105°C. Applications requiring operation above 105°C must retain the original Samtec part or identify alternative solutions.

The TSW-107-08-S-S features gold-plated mating contacts with phosphor bronze material, while the 3-644456-7 uses tin-plated copper alloy contacts. Both finishes and materials are suitable for standard solder-terminated applications; contact finish selection depends on specific environmental and reliability requirements.

Both parts carry appropriate RoHS compliance certifications and maintain MSL 1 (Unlimited) moisture sensitivity ratings, supporting standard handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the 3-644456-7 directly replace the TSW-107-08-S-S in all applications?

A: The 3-644456-7 is functionally equivalent for applications operating within -55°C to 105°C. Applications requiring operation above 105°C require verification of alternative solutions or retention of the original TSW-107-08-S-S specification.

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

A: The TSW-107-08-S-S uses gold-plated mating contacts (30.0µin thickness) on phosphor bronze material. The 3-644456-7 uses tin-plated mating contacts (150.0µin thickness) on copper alloy material. Both finishes are suitable for solder-terminated applications; selection depends on corrosion resistance and contact wear requirements specific to the application environment.

Q: Are both parts RoHS compliant?

A: Yes. The TSW-107-08-S-S is ROHS3 Compliant, and the 3-644456-7 is RoHS Compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What is the difference in insulation material?

A: The TSW-107-08-S-S uses Polybutylene Terephthalate (PBT), while the 3-644456-7 uses Thermoplastic material. Both materials provide UL94 V-0 flammability ratings and are suitable for standard through-hole applications.

Q: Are there differences in contact length specifications?

A: Yes. The TSW-107-08-S-S has a mating contact length of 0.230" (5.84mm) and post length of 0.200" (5.08mm). The 3-644456-7 has a mating contact length of 0.295" (7.49mm) and post length of 0.110" (2.79mm). These dimensional differences may affect board layout and mating depth; verify compatibility with corresponding receptacle or cable assembly specifications.

Q: What is the fastening type difference?

A: The TSW-107-08-S-S specifies Push-Pull fastening. The 3-644456-7 does not specify a fastening type. Confirm mating interface requirements with the corresponding connector or cable assembly documentation.
