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. This 7-position, single-row header operates at 0.100" (2.54mm) pitch and is classified as an active product. The connector features male pins with gold-plated mating contacts and tin-plated posts, suitable for board-to-board or cable interconnections. 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 inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 3-644456-7 (TE Connectivity AMP Connectors, MTA-100 series) qualifies as an equivalent based on the following critical parameters:

• Identical pitch specification: 0.100" (2.54mm)
• Matching position count: 7 positions, single row
• Equivalent connector type: Header with male pins
• Identical mounting method: Through-hole solder termination
• Matching insulation height: 0.100" (2.54mm)
• Identical contact shape: Square
• Equivalent shrouding configuration: Unshrouded
• Matching flammability rating: UL94 V-0
• Equivalent moisture sensitivity: MSL 1 (Unlimited)
• Aligned regulatory compliance: RoHS and REACH status

Substitution is valid where the application tolerates the specified parameter variations documented in the Parameter Comparison table.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-107-08-S-S and 3-644456-7 maintain active product status and comply with RoHS and REACH regulatory requirements. The TSW-107-08-S-S offers a higher operating temperature ceiling of 125°C compared to the substitute's 105°C maximum, making it preferable for elevated-temperature applications. The TSW-107-08-S-S features gold-plated mating contacts with phosphor bronze base material, while the 3-644456-7 employs tin plating on copper alloy contacts. Contact length variations exist between the two designs, with the TSW-107-08-S-S providing longer mating contact length (0.230" vs. 0.295") and longer post length (0.200" vs. 0.110"). Selection should account for PCB stack-up requirements and mating depth specifications. Both connectors share identical pitch, position count, and flammability ratings, supporting functional interchangeability in standard applications operating within the 3-644456-7's temperature range.

Frequently Asked Questions (FAQ)

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

A: Functional substitution is valid for applications operating within -55°C to 105°C. Applications requiring operation above 105°C must use the TSW-107-08-S-S. Contact length differences may affect PCB design; verify mating depth and stack-up compatibility before substitution.

Q: What are the key differences between these connectors?

A: Primary differences include operating temperature range (TSW-107-08-S-S: 125°C maximum vs. 3-644456-7: 105°C maximum), contact finish (gold vs. tin), base contact material (phosphor bronze vs. copper alloy), and contact length specifications. Both share identical pitch (2.54mm), position count (7), and mounting method (through-hole solder).

Q: Are both connectors 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 significance of contact finish differences?

A: The TSW-107-08-S-S uses gold plating (30.0µin thickness) for enhanced corrosion resistance and lower contact resistance. The 3-644456-7 uses tin plating (150.0µin thickness), which provides adequate performance for standard applications but may exhibit higher contact resistance in low-signal applications.

Q: Do these connectors have identical moisture sensitivity?

A: Yes. Both connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging differences exist?

A: The TSW-107-08-S-S is supplied in Bag packaging, while the 3-644456-7 is supplied in Bulk packaging. This affects inventory management and component handling but does not impact electrical or mechanical performance.
