Substitute Part Grouping Explanation

Substitute parts for the TSW-105-19-G-D-LL are determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (10) and row configuration (2 rows)
Mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
Mounting type (Through Hole)
Termination method (Kinked Pin, Solder)
Fastening type (Push-Pull)
Contact finish (Gold)
Contact material (Phosphor Bronze)
Operating temperature range (-55°C ~ 125°C)

Engineering Selection Recommendations

Both the TSW-105-19-G-D-LL and HTSW-105-19-G-D-LL are active products from Samtec Inc. with identical electrical and mechanical specifications. Both parts are ROHS3 compliant and carry EAR99 export classification. Selection between these parts should be based on inventory availability and application-specific requirements related to insulation material properties. The TSW series uses PBT insulation, while the HTSW series uses LCP insulation. Both materials meet UL94 V-0 flammability requirements and support the full operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can HTSW-105-19-G-D-LL be used as a direct replacement for TSW-105-19-G-D-LL?

A: Yes. Both parts share identical connector type, contact configuration, pitch spacing, mounting method, termination style, and contact specifications. The primary difference is insulation material composition (PBT vs. LCP), which does not affect functional compatibility when both materials meet the same flammability and temperature requirements.

Q: What are the key compatibility factors for these connectors?

A: Compatibility is determined by matching pitch (0.100" / 2.54mm), position count (10), row configuration (2 rows), contact type (male pin), mounting method (through hole), and termination (kinked pin solder). Both parts meet these criteria identically.

Q: Are there any differences in environmental performance between these parts?

A: Both parts operate across -55°C to 125°C and meet UL94 V-0 flammability standards. The insulation material difference (PBT vs. LCP) may affect specific environmental properties such as moisture absorption or chemical resistance, but both materials are suitable for standard industrial applications within the specified operating range.

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

A: PBT (Polybutylene Terephthalate) and LCP (Liquid Crystal Polymer) are both high-performance thermoplastics meeting the same flammability rating. LCP typically offers superior dimensional stability and lower moisture absorption. Selection should be based on specific application environmental conditions and material compatibility requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-105-19-G-D-LL and HTSW-105-19-G-D-LL are ROHS3 compliant and carry identical export classification (EAR99) and tariff codes (HTSUS 8536.69.4040).
