Substitute Part Grouping Explanation

Substitute parts for the HTSS-107-03-L-D are identified based on the following critical parameters that determine functional equivalence:

Matching Parameters (Required for Substitution):

• Number of Positions: 14
• 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
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts TSS-107-03-L-D and TST-107-03-L-D meet all critical matching parameters. Variations in insulation material (LCP versus PBT or glass-filled PBT) and insulation color do not affect electrical or mechanical compatibility for standard through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—HTSS-107-03-L-D, TSS-107-03-L-D, and TST-107-03-L-D—maintain Active product status and comply with ROHS3 requirements. Each part carries UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating unlimited shelf life under standard storage conditions.

Selection between these parts is determined by application-specific requirements:

HTSS-107-03-L-D employs Liquid Crystal Polymer (LCP) insulation material with natural color. LCP provides superior dimensional stability and chemical resistance in high-temperature or demanding environmental conditions.

TSS-107-03-L-D uses standard Polybutylene Terephthalate (PBT) insulation with black color. PBT offers cost-effective performance for general-purpose board-to-board applications.

TST-107-03-L-D incorporates glass-filled PBT insulation with black color and specifies 3.4A per contact current rating. The glass-filled formulation provides enhanced mechanical strength and thermal performance, suitable for board-to-cable/wire interconnections requiring higher current capacity.

All three parts are electrically and mechanically interchangeable within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can TSS-107-03-L-D or TST-107-03-L-D be used as direct replacements for HTSS-107-03-L-D?

A: Yes. All three parts share identical electrical and mechanical specifications including pitch, row spacing, contact geometry, contact finish, and operating temperature range. The primary differences are insulation material composition and color, which do not affect connector functionality or mating compatibility.

Q: What is the difference between the insulation materials used in these parts?

A: HTSS-107-03-L-D uses Liquid Crystal Polymer (LCP), which offers superior dimensional stability and chemical resistance. TSS-107-03-L-D uses standard PBT, and TST-107-03-L-D uses glass-filled PBT. Glass-filled PBT provides enhanced mechanical strength compared to standard PBT. Material selection depends on environmental and mechanical requirements of the specific application.

Q: Does the insulation color affect compatibility?

A: No. Insulation color (natural versus black) is a visual identifier only and does not affect electrical or mechanical compatibility. All parts function identically in circuit applications.

Q: What is the significance of the current rating specified for TST-107-03-L-D?

A: The TST-107-03-L-D specifies 3.4A per contact current rating. This specification is provided for applications requiring explicit current capacity documentation. The other parts do not list current ratings in the provided data but maintain identical contact geometry and material composition.

Q: Are all three parts RoHS compliant?

A: Yes. HTSS-107-03-L-D, TSS-107-03-L-D, and TST-107-03-L-D are all ROHS3 compliant with MSL 1 moisture sensitivity level, indicating unlimited shelf life under standard storage conditions.

Q: What is the difference between "Board to Board or Cable" and "Board to Cable/Wire" style designations?

A: HTSS-107-03-L-D and TSS-107-03-L-D are designated for board-to-board or cable applications. TST-107-03-L-D is designated for board-to-cable/wire applications. This designation reflects the intended mating interface; however, the physical connector specifications remain identical across all three parts.
