Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-105-03-T-D is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 10
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Shrouding: Shrouded - 4 Wall
• Mounting Type: Through Hole
• Termination: Solder
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Tin
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature: -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The TST-105-03-T-D qualifies as a substitute part based on matching all critical electrical and mechanical parameters. Minor variations in insulation material composition (glass-filled PBT) and connector style designation (Board to Cable/Wire versus Board to Board or Cable) do not affect functional interchangeability for standard through-hole header applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-105-03-T-D and TST-105-03-T-D are active production parts manufactured by Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts may be based on inventory availability, supply chain considerations, or design requirements specific to the TST series characteristics. The TST-105-03-T-D currently maintains higher inventory levels at 1108 units compared to 940 units for the TSS-105-03-T-D. Both parts meet identical electrical and mechanical specifications for standard through-hole header applications requiring 10-position, 2.54mm pitch connectors with shrouded 4-wall construction.

Frequently Asked Questions (FAQ)

Q: Are TSS-105-03-T-D and TST-105-03-T-D fully interchangeable?

A: Yes. Both parts share identical connector type, contact configuration, pitch, position count, row spacing, shrouding, mounting method, termination type, contact material, contact finish, insulation material base composition, operating temperature range, and flammability rating. The TST variant uses glass-filled PBT insulation, which provides enhanced mechanical properties while maintaining functional compatibility.

Q: What is the difference between the TSS and TST series designations?

A: The TSS and TST series are both Flex Stack connector lines from Samtec Inc. The primary distinction lies in the connector style application: TSS is designated for board-to-board or cable applications, while TST is designated for board-to-cable/wire applications. Both series maintain identical electrical and mechanical specifications for the 10-position, 2.54mm pitch header configuration.

Q: Can I substitute TST-105-03-T-D for TSS-105-03-T-D in existing designs?

A: Substitution is permissible based on matching electrical and mechanical parameters. The glass-filled PBT insulation in the TST variant may provide improved dimensional stability and mechanical strength. Design validation should confirm that the TST series characteristics align with application requirements.

Q: What are the critical parameters for header connector substitution?

A: Critical parameters include connector type (header), contact type (male pin), mating pitch (0.100" / 2.54mm), position count (10), row count (2), row spacing (0.100" / 2.54mm), shrouding configuration (shrouded 4-wall), mounting type (through-hole), termination method (solder), contact material (phosphor bronze), contact finish (tin), and insulation material (PBT-based). Deviation in any of these parameters indicates non-interchangeability.

Q: Are there current or voltage rating differences between these parts?

A: Current and voltage ratings are not specified in the provided technical data for either part. Applications requiring specific current or voltage performance should reference detailed datasheets or contact the manufacturer for rated specifications.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
