TSW-103-23-G-S Equivalent & Substitute Parts

Part Overview

The TSW-103-23-G-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications requiring a 3-position, single-row vertical configuration with 0.100" (2.54mm) pitch. This connector is classified as discontinued at DiGi Electronics, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning. The part operates across a wide temperature range of -55°C to 125°C and features gold-plated phosphor bronze contacts with PBT insulation rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-103-23-G-S is determined by strict alignment of the following parameters:

• Connector Type: Header (with or without breakaway feature)
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 3
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Material: Polybutylene Terephthalate (PBT) or PBT-based compounds
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0

The substitute part 929647-01-03-I (3M) meets all critical substitution criteria. Both parts share identical mating pitch, position count, row configuration, mounting methodology, and termination approach. Contact geometry, insulation material composition, and flammability ratings are equivalent across both designs.

Parameter Comparison

Engineering Selection Recommendations

The 929647-01-03-I (3M) is a qualified substitute for the TSW-103-23-G-S based on the following engineering criteria:

Product Status: The 3M part maintains active product status with confirmed inventory availability (1958 pcs), whereas the Samtec part is discontinued. This availability differential supports transition to the 3M alternative for new procurement cycles.

Compliance & Certifications: Both parts achieve UL94 V-0 flammability rating, RoHS compliance, REACH unaffected status, and MSL 1 classification. Regulatory and environmental compliance requirements are satisfied by the substitute.

Electrical & Mechanical Compatibility: Identical mating pitch (0.100"), position count (3), row configuration (1), contact geometry (square male pins), and termination method (solder) ensure mechanical and electrical interchangeability within standard PCB footprints designed for the original part.

Operating Temperature Consideration: The TSW-103-23-G-S operates across -55°C to 125°C, while the 929647-01-03-I operates across -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must retain the original Samtec specification or identify alternative solutions.

Contact Material Variance: The Samtec part uses phosphor bronze contacts; the 3M part uses copper alloy contacts. Both materials with gold plating provide equivalent electrical performance for standard signal and low-power applications.

Frequently Asked Questions (FAQ)

Q: Can the 929647-01-03-I directly replace the TSW-103-23-G-S on existing PCBs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (3), row spacing, and through-hole mounting footprint. No PCB redesign is required for mechanical or electrical compatibility.

Q: What is the significance of the "Breakaway" feature on the 3M part?

A: The breakaway feature allows individual connector positions to be separated after assembly. This does not affect compatibility with standard mating connectors or PCB footprints. The breakaway capability is an additional feature that does not compromise substitution eligibility.

Q: Are there temperature limitations when substituting?

A: Yes. The original TSW-103-23-G-S supports -55°C to 125°C operation. The 929647-01-03-I supports -40°C to 105°C. Applications requiring operation outside the 3M part's temperature range must retain the original specification or identify alternative solutions rated for the required temperature extremes.

Q: Does the difference in contact material (phosphor bronze vs. copper alloy) affect performance?

A: For standard signal and low-power applications, both materials with gold plating provide equivalent electrical performance. Contact resistance and reliability are comparable under normal operating conditions.

Q: What is the current rating difference between the two parts?

A: The TSW-103-23-G-S does not specify a current rating. The 929647-01-03-I specifies 2.5A per contact. For applications requiring current-carrying capacity verification, the 3M part's 2.5A rating provides a defined electrical specification.

Q: Are both parts RoHS compliant?

A: Yes. The TSW-103-23-G-S is ROHS3 compliant. The 929647-01-03-I is RoHS compliant. Both meet RoHS regulatory requirements for new designs and procurement.

Q: What is the inventory status for each part?

A: The TSW-103-23-G-S is discontinued at DiGi Electronics with 1063 pcs reported in stock. The 929647-01-03-I is active with 1958 pcs in stock, providing superior long-term availability for ongoing production requirements.
