TSW-103-08-S-S Equivalent & Substitute Parts

Part Overview

The TSW-103-08-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications requiring a 3-position, 0.100" (2.54mm) pitch vertical header with male pins. This connector is classified as discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and component procurement.

The primary reason for identifying substitute parts is the discontinued product status, which restricts future availability and necessitates alternative sourcing strategies for new production runs or design revisions.

Key Parameters

Substitute Part Grouping Explanation

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

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 3 — exact match required
• Number of Rows: 1 — exact match required
• Connector Type: Header — exact match required
• Contact Type: Male Pin — exact match required
• Mounting Type: Through Hole — exact match required
• Termination: Solder — exact match required
• Insulation Material: Polybutylene Terephthalate (PBT) — compatible material required

The substitute part 929647-02-03-I (3M) meets all critical substitution criteria. Both connectors share identical mating pitch, position count, row configuration, and mounting methodology. Both employ solder termination and PBT-based insulation materials, ensuring mechanical and electrical compatibility in board-level applications.

Parameter Comparison

Engineering Selection Recommendations

The 929647-02-03-I (3M) is the qualified substitute for the TSW-103-08-S-S based on the following engineering criteria:

Product Status: The 929647-02-03-I maintains active product status with current manufacturing support, whereas the TSW-103-08-S-S is discontinued. This ensures long-term component availability and supply chain continuity.

Compliance & Certifications: Both parts maintain UL94 V-0 flammability ratings and REACH compliance. The 929647-02-03-I holds RoHS Compliant status, meeting modern regulatory requirements equivalent to the ROHS3 Compliant designation of the original part.

Mechanical Compatibility: Both connectors share identical mating pitch (0.100"), position count (3), row configuration (1), and through-hole mounting methodology. Contact length variations (0.005" mating, 0.010" post) fall within acceptable mechanical tolerances for standard board-level applications.

Electrical Compatibility: Both employ gold-plated mating contacts and square contact geometry, ensuring equivalent signal integrity and mating force characteristics. The 929647-02-03-I provides a 2.5A current rating specification, whereas the original part does not specify current capacity.

Temperature Considerations: The TSW-103-08-S-S operates across -55°C to 125°C, while the 929647-02-03-I operates across -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must retain the original part or identify alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the 929647-02-03-I directly replace the TSW-103-08-S-S in existing designs?

A: Yes, for applications operating within the -40°C to 105°C temperature range. The connectors share identical mating pitch, position count, row configuration, and mounting type. Contact length variations are within standard mechanical tolerances for board-level applications.

Q: What is the significance of the "Breakaway" designation on the 929647-02-03-I?

A: The breakaway feature allows individual positions to be separated from the header assembly. This does not affect compatibility with standard mating connectors and provides additional design flexibility for applications requiring modular configurations.

Q: Are there temperature limitations when substituting?

A: Yes. The original TSW-103-08-S-S supports -55°C to 125°C operation, while the 929647-02-03-I supports -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the original part or identify alternative solutions rated for the required temperature range.

Q: What are the differences in contact finish between these parts?

A: The TSW-103-08-S-S uses tin-plated posts, while the 929647-02-03-I uses gold-plated posts. Both employ gold-plated mating contacts. Gold plating on posts provides improved corrosion resistance and is generally preferred for long-term reliability.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts maintain UL94 V-0 flammability ratings and REACH compliance. The 929647-02-03-I holds RoHS Compliant status, meeting modern regulatory standards.

Q: What is the packaging difference between these parts?

A: The TSW-103-08-S-S packaging is not specified in available data. The 929647-02-03-I is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: Are there any current rating specifications?

A: The 929647-02-03-I specifies a 2.5A current rating. The TSW-103-08-S-S does not provide a current rating specification in available data. Verify current requirements for your application.
