Substitute Part Grouping Explanation

Substitute parts for the TSW-110-07-SS-D are identified based on strict equivalence of the following critical parameters:

Number of Positions: 20
Number of Rows: 2
Pitch - Mating: 0.100" (2.54mm)
Row Spacing - Mating: 0.100" (2.54mm)
Connector Type: Header
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder
Contact Material: Phosphor Bronze
Contact Finish - Mating: Gold
Operating Temperature: -55°C ~ 125°C
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant

The identified substitutes maintain these core electrical and mechanical parameters. Variations in insulation material (PBT versus Liquid Crystal Polymer) and series designation (TSW versus HTSW) do not affect functional compatibility when these critical parameters remain constant.

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment for current applications. The TSW-110-07-S-D offers the highest inventory availability at 3016 units, providing supply chain advantage while maintaining identical electrical and mechanical specifications to the primary part. The HTSW-110-07-SM-D utilizes Liquid Crystal Polymer insulation material instead of PBT, with MSL classification as Not Applicable rather than MSL 1, reflecting different material properties suitable for specific environmental conditions. Selection between these substitutes should be based on inventory requirements, material specifications for the target application environment, and design validation against the specific insulation material properties.

Frequently Asked Questions (FAQ)

Q: Can TSW-110-07-S-D be used as a direct replacement for TSW-110-07-SS-D?

A: Yes. Both parts share identical electrical and mechanical parameters including 20 positions, 2 rows, 0.100" pitch, through-hole mounting, solder termination, phosphor bronze contacts with gold mating finish, and operating temperature range of -55°C to 125°C. Both maintain ROHS3 compliance and UL94 V-0 flammability rating.

Q: What is the difference between TSW-110-07-SS-D and HTSW-110-07-SM-D?

A: The primary difference is insulation material: TSW-110-07-SS-D uses Polybutylene Terephthalate (PBT) with MSL 1 classification, while HTSW-110-07-SM-D uses Liquid Crystal Polymer (LCP) with MSL Not Applicable. All other electrical and mechanical parameters remain equivalent. The series designation (TSW versus HTSW) reflects this material variation.

Q: Are there compatibility concerns when substituting between these parts?

A: No compatibility concerns exist for the identified substitutes. All three parts maintain identical mating pitch, row spacing, contact configuration, and termination method. Insulation material differences do not affect electrical or mechanical compatibility in standard applications.

Q: How does inventory availability factor into part selection?

A: TSW-110-07-S-D maintains the highest inventory at 3016 units, compared to 805 units for TSW-110-07-SS-D and 936 units for HTSW-110-07-SM-D. Inventory levels should be considered for supply chain planning and lead time requirements.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant, UL94 V-0 rated for flammability, and classified under ECCN EAR99 with HTSUS code 8536.69.4040. These certifications ensure regulatory alignment across all identified substitutes.
