Substitute Part Grouping Explanation

Substitution eligibility for the TSW-103-08-TM-S is determined by the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Pitch specification (0.100" / 2.54mm)
Number of positions (3)
Number of rows (1)
Mounting method (Through Hole)
Termination type (Solder)
Fastening mechanism (Push-Pull)
Operating temperature range (-55°C ~ 105°C)
Flammability compliance (UL94 V-0)
RoHS compliance status (ROHS3)

Parts matching all these parameters are classified as direct substitutes. Variations in insulation material (PBT vs. LCP) and contact finish specifications do not affect functional substitution when all primary parameters align.

Engineering Selection Recommendations

All three parts—TSW-103-08-TM-S, TSW-103-08-T-S, and HTSW-103-08-TM-S—are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on availability and specific application requirements:

TSW-103-08-TM-S and TSW-103-08-T-S differ only in series designation within the TSW family, with both utilizing PBT insulation material. The TSW-103-08-T-S variant currently maintains higher inventory availability (1828 pcs vs. 695 pcs).

HTSW-103-08-TM-S represents the HTSW series alternative with Liquid Crystal Polymer (LCP) insulation material, offering different thermal and mechanical properties while maintaining all critical electrical and mechanical compatibility parameters. This variant is suitable for applications requiring LCP insulation characteristics.

All three parts maintain identical pitch, position count, contact geometry, operating temperature range, and compliance certifications, ensuring functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can TSW-103-08-T-S replace TSW-103-08-TM-S in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications including pitch (0.100"), position count (3), contact type (male pin), mounting method (through hole), and operating temperature range (-55°C ~ 105°C). The series designation difference does not affect functional compatibility.

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

A: The TSW series uses Polybutylene Terephthalate (PBT) insulation, while the HTSW-103-08-TM-S uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements and operate across the specified temperature range. Material selection depends on specific application thermal and mechanical requirements.

Q: Are all three parts RoHS compliant?

A: Yes. TSW-103-08-TM-S, TSW-103-08-T-S, and HTSW-103-08-TM-S are all ROHS3 compliant with EAR99 export classification.

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

A: TSW-103-08-TM-S and TSW-103-08-T-S are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. HTSW-103-08-TM-S is rated Not Applicable for MSL.

Q: Can these connectors be used interchangeably in board-to-board and cable applications?

A: Yes. All three parts are specified for board-to-board or cable connection styles with identical contact geometry, pitch, and fastening mechanisms (push-pull), supporting interchangeable use across both application types.
