Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-103-07-S-S-LL is determined by the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 3
• Number of Rows: 1
• Mounting Type: Through Hole
• Contact Finish - Mating: Gold
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The TSW-103-07-S-S meets all critical substitution criteria. Both parts share identical connector topology, mating pitch, position count, mounting method, contact finish specification, thermal operating range, and regulatory compliance status. Variations in insulation material (LCP vs. PBT) and termination style (Kinked Pin, Solder vs. Solder) do not affect electrical or mechanical interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-103-07-S-S-LL and TSW-103-07-S-S are Active status products from Samtec Inc. with full RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

• Insulation material requirements: HTSW series uses Liquid Crystal Polymer (LCP); TSW series uses Polybutylene Terephthalate (PBT)
• Termination preference: HTSW features Kinked Pin, Solder termination; TSW features standard Solder termination
• Inventory availability and lead time considerations
• Moisture sensitivity level: HTSW-103-07-S-S-LL is Not Applicable; TSW-103-07-S-S is MSL 1 (Unlimited)

Both parts satisfy identical electrical and mechanical interface requirements and operate across the full -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Are HTSW-103-07-S-S-LL and TSW-103-07-S-S mechanically interchangeable?

A: Yes. Both parts share identical mating pitch (0.100"), position count (3), row configuration (1), contact dimensions, and mounting type (through-hole). They are mechanically interchangeable in board-level applications.

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

A: The HTSW-103-07-S-S-LL uses Liquid Crystal Polymer (LCP) insulation, while the TSW-103-07-S-S uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and operate across the specified temperature range.

Q: Do both parts have the same contact finish specifications?

A: Yes. Both parts feature gold-plated mating contacts (30.0µin / 0.76µm thickness) and tin-plated posts, ensuring equivalent electrical performance and corrosion resistance.

Q: What is the significance of the moisture sensitivity level difference?

A: The HTSW-103-07-S-S-LL has MSL Not Applicable, while the TSW-103-07-S-S has MSL 1 (Unlimited). This indicates the TSW series has no moisture sensitivity restrictions for storage and handling.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the HTSW-103-07-S-S-LL and TSW-103-07-S-S are ROHS3 Compliant and carry EAR99 export classification.

Q: What is the difference in termination style?

A: The HTSW-103-07-S-S-LL features Kinked Pin, Solder termination, while the TSW-103-07-S-S features standard Solder termination. Both are suitable for through-hole PCB assembly.
