Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-103-27-L-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Number of Positions: 3 — must match for circuit board layout and connector interface
• Number of Rows: 1 — must match for physical footprint
• Connector Type: Header — must match for board-to-board or cable connection application
• Contact Type: Male Pin — must match for mating interface
• Mounting Type: Through Hole — must match for PCB assembly process
• Termination: Solder — must match for assembly compatibility
• Operating Temperature Range: -55°C ~ 125°C — substitute must support this range
• RoHS Status: ROHS3 Compliant — substitute must maintain compliance

The HTSW-103-27-L-S qualifies as a substitute part because it matches all critical parameters. Variations in insulation material (PBT versus LCP) and insulation color do not affect electrical or mechanical compatibility within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-103-27-L-S and HTSW-103-27-L-S are active production parts manufactured by Samtec Inc. and maintain ROHS3 compliance with identical electrical and mechanical specifications. Selection between these parts is based on availability and inventory status rather than technical performance differences.

The TSW-103-27-L-S (1107 units in stock) is the primary specification. The HTSW-103-27-L-S (913 units in stock) serves as a direct substitute when primary inventory is unavailable. Both parts support the same operating temperature range (-55°C ~ 125°C) and carry identical UL94 V-0 flammability ratings.

The difference in insulation material (PBT in TSW-103-27-L-S versus LCP in HTSW-103-27-L-S) does not affect compatibility or performance within specified operating conditions. Both materials meet the same flammability and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can HTSW-103-27-L-S be used as a direct replacement for TSW-103-27-L-S?

A: Yes. Both parts share identical pitch (0.100"), position count (3), row configuration (1), contact geometry, and operating temperature range. The connector footprint and mating interface are identical.

Q: What is the difference between the TSW and HTSW series?

A: The primary difference is insulation material: TSW-103-27-L-S uses Polybutylene Terephthalate (PBT), while HTSW-103-27-L-S uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements and support the same operating temperature range.

Q: Are there any compatibility concerns with PCB layout or assembly?

A: No. Both parts have identical through-hole mounting specifications, solder termination requirements, and physical dimensions. PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TSW-103-27-L-S and HTSW-103-27-L-S are ROHS3 compliant with EAR99 export classification and 8536.69.4040 HTSUS code.

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

A: TSW-103-27-L-S has MSL 1 (Unlimited). HTSW-103-27-L-S is listed as Not Applicable, indicating no moisture sensitivity restrictions for either part.
