Substitute Part Grouping Explanation

Substitute parts for the TSW-107-11-L-S are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria include:

Critical Parameters for Substitution:

Connector Type: Header
Contact Type: Male Pin
Number of Positions: 7
Number of Rows: 1
Pitch - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole
Termination: Solder
Contact Length - Mating: 0.230" (5.84mm)
Contact Length - Post: 0.600" (15.24mm)
Overall Contact Length: 0.930" (23.62mm)
Insulation Height: 0.100" (2.54mm)
Contact Shape: Square
Contact Finish - Mating: Gold
Contact Finish - Post: Tin
Contact Material: Phosphor Bronze
Operating Temperature: -55°C ~ 125°C
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant

The HTSW-107-11-L-S qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. Variations in insulation material (LCP versus PBT) and MSL classification do not affect functional compatibility in standard through-hole solder applications.

Engineering Selection Recommendations

Both TSW-107-11-L-S and HTSW-107-11-L-S are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts is based on supply availability and inventory status rather than functional performance differences.

The TSW-107-11-L-S features PBT insulation material with MSL 1 (Unlimited) moisture sensitivity classification. The HTSW-107-11-L-S uses LCP insulation material with Not Applicable MSL classification. Both materials meet the specified operating temperature range of -55°C to 125°C and maintain identical electrical and mechanical interface characteristics.

For applications requiring immediate component availability, inventory levels should be evaluated. Current stock status shows 1104 pieces for TSW-107-11-L-S and 1765 pieces for HTSW-107-11-L-S in new original condition.

Frequently Asked Questions (FAQ)

Q: Are TSW-107-11-L-S and HTSW-107-11-L-S mechanically interchangeable?

A: Yes. Both parts maintain identical pitch (0.100" / 2.54mm), contact geometry, mounting type (through-hole solder), and overall dimensions. They are direct mechanical substitutes.

Q: What is the difference between PBT and LCP insulation materials in these connectors?

A: PBT (polybutylene terephthalate) and LCP (liquid crystal polymer) are both thermoplastic materials meeting UL94 V-0 flammability requirements. The material difference does not affect electrical performance or mechanical compatibility in standard through-hole applications.

Q: Do both parts support the same operating temperature range?

A: Yes. Both TSW-107-11-L-S and HTSW-107-11-L-S operate across -55°C to 125°C.

Q: What does MSL 1 (Unlimited) mean for the TSW-107-11-L-S?

A: MSL 1 indicates the component has unlimited shelf life without moisture absorption concerns, requiring no special storage or handling precautions prior to soldering.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-107-11-L-S and HTSW-107-11-L-S are ROHS3 compliant.

Q: Can these connectors be used for board-to-board or cable applications?

A: Yes. Both parts are specified for board-to-board or cable interconnection with solder termination and push-pull fastening.
