Substitute Part Grouping Explanation

Substitution eligibility for the TSW-101-08-TM-S is determined by strict equivalence across the following critical parameters:

Manufacturer and Series: Both parts must be from Samtec Inc. TSW series
Connector Type and Contact Type: Header with male pin contacts
Position Configuration: Single position, single row
Mounting and Termination: Through-hole solder termination
Fastening Mechanism: Push-pull fastening
Physical Dimensions: Contact lengths, insulation height, and overall contact length
Material Specifications: Phosphor bronze contacts with tin finish, PBT insulation
Environmental Ratings: Operating temperature range -55°C to 105°C, UL94 V-0 flammability rating
Compliance: ROHS3 compliant, MSL 1 rating

The substitute part TSW-101-08-T-S meets all these criteria and is therefore electrically and mechanically equivalent for direct substitution in applications requiring the TSW-101-08-TM-S.

Engineering Selection Recommendations

Both the TSW-101-08-TM-S and TSW-101-08-T-S are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: TSW-101-08-TM-S has 827 units in stock, while TSW-101-08-T-S has 737 units in stock. Both parts are ROHS3 compliant with MSL 1 rating, indicating no moisture sensitivity restrictions. Both carry EAR99 export classification and are subject to the same HTSUS tariff code. For applications requiring immediate availability or long-term supply assurance, either part is suitable for direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can TSW-101-08-T-S be used as a direct replacement for TSW-101-08-TM-S?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters including contact geometry, material composition, termination method, and environmental ratings are identical. No circuit board redesign or connector interface modification is required.

Q: Are there any differences in the fastening mechanism between these parts?

A: No. Both parts use push-pull fastening and are designed for board-to-board or cable applications with identical mating and post contact lengths.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, carry UL94 V-0 flammability rating, have MSL 1 moisture sensitivity level, and share the same ECCN and HTSUS classifications.

Q: What is the difference between the part numbers TSW-101-08-TM-S and TSW-101-08-T-S?

A: The part numbers differ only in the designation between "TM" and "T". Both designations refer to equivalent connector headers within the Samtec TSW series with identical specifications and performance characteristics.

Q: Are there any temperature or environmental limitations for these connectors?

A: Both parts operate across the temperature range of -55°C to 105°C and are rated UL94 V-0 for flammability. No additional environmental restrictions apply beyond standard handling for MSL 1 components.

Q: Can these connectors be used in high-reliability applications?

A: Both parts meet standard industrial specifications with phosphor bronze contacts, tin finish, and PBT insulation. Suitability for specific high-reliability applications depends on system-level requirements beyond component specifications.
