Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSS-107-03-G-D are identified based on strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 14
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variations in insulation material (PBT versus LCP), insulation color, application style (board-to-board versus board-to-cable), and series designation do not preclude substitution when all critical electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TSS-107-03-G-D, HTSS-107-03-G-D, and TST-107-03-G-D—maintain active product status and full ROHS3 compliance with UL94 V-0 flammability certification. The parts are functionally equivalent across all critical electrical and mechanical parameters including connector geometry, contact configuration, pitch spacing, and operating temperature range.

Selection between these parts depends on application-specific requirements:

The TSS-107-03-G-D (PBT insulation, board-to-board or cable style) and TST-107-03-G-D (glass-filled PBT insulation, board-to-cable/wire style) both utilize polybutylene terephthalate-based insulation materials. The TST-107-03-G-D specifies a current rating of 3.4A per contact, whereas the TSS-107-03-G-D does not specify a current rating in the provided data.

The HTSS-107-03-G-D employs liquid crystal polymer (LCP) insulation with natural color designation, offering an alternative material composition while maintaining identical electrical and mechanical specifications.

All parts carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can TST-107-03-G-D replace TSS-107-03-G-D in a board-to-board application?

A: The TST-107-03-G-D is designated for board-to-cable/wire applications, whereas the TSS-107-03-G-D supports board-to-board or cable configurations. While the electrical and mechanical parameters are equivalent, the application style designation should be verified against specific board layout and mating connector requirements.

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

A: The TSS-107-03-G-D and TST-107-03-G-D use polybutylene terephthalate (PBT), with the TST variant including glass reinforcement. The HTSS-107-03-G-D uses liquid crystal polymer (LCP). All three materials meet UL94 V-0 flammability requirements and operate across the identical temperature range of -55°C to 125°C. Material selection depends on specific thermal, mechanical, or chemical resistance requirements of the application.

Q: Does the glass-filled PBT in TST-107-03-G-D provide enhanced mechanical properties?

A: Glass-filled PBT typically offers improved mechanical strength and dimensional stability compared to unfilled PBT. However, the provided data does not specify mechanical property differences between the TSS-107-03-G-D and TST-107-03-G-D beyond the material composition designation.

Q: Are all three parts interchangeable from a PCB footprint perspective?

A: Yes. All three parts share identical pitch spacing (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), contact length specifications, and overall dimensions. PCB footprints designed for any one of these parts accommodate the others without modification.

Q: What is the significance of the current rating specification in TST-107-03-G-D?

A: The TST-107-03-G-D specifies a current rating of 3.4A per contact. The TSS-107-03-G-D and HTSS-107-03-G-D do not include current rating specifications in the provided data. Applications requiring explicit current rating documentation should reference the TST-107-03-G-D or consult manufacturer datasheets for the other variants.

Q: Are there any moisture handling differences between these parts?

A: All three parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard handling procedures apply without special desiccant packaging or baking requirements prior to assembly.

Q: How do the insulation color differences affect part selection?

A: The TSS-107-03-G-D and TST-107-03-G-D feature black insulation, while the HTSS-107-03-G-D has natural color insulation. Color designation does not affect electrical or mechanical performance and is primarily a visual identification characteristic.
