TSW-133-07-T-D Equivalent & Substitute Parts

Part Overview

The TSW-133-07-T-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 66-position, 2-row connector operates across a wide temperature range (-55°C to 105°C) and features tin-plated phosphor bronze contacts with push-pull fastening. The part maintains Active product status with full inventory availability. Substitute parts are identified to address specific application requirements or supply chain considerations while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSW-133-07-T-D are evaluated based on the following critical parameters that determine functional compatibility:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB layout compatibility
• Number of Rows: 2 — maintains board-to-board spacing requirements
• Connector Type: Header with male pin contacts — ensures mating interface compatibility
• Mounting Type: Through Hole — preserves assembly process compatibility
• Termination: Solder — maintains soldering process requirements
• Fastening Type: Push-Pull — ensures mechanical engagement consistency
• Operating Temperature Range: Must encompass or match the -55°C to 105°C specification
• Material Flammability Rating: UL94 V-0 — maintains safety compliance
• RoHS Status: ROHS3 Compliant — ensures regulatory compliance

The substitute part 4-103328-5 (TE Connectivity AMP Connectors) shares these core parameters with the main part. The primary difference is the number of positions (80 vs. 66), which represents a higher-capacity variant suitable for applications requiring additional contact positions while maintaining identical pitch, row spacing, and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TSW-133-07-T-D maintains Active product status with established supply chain availability. The substitute part 4-103328-5 carries Obsolete product status, which may present long-term sourcing challenges and should be considered only when the 80-position configuration is functionally required.

Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements. The main part operates across -55°C to 105°C, while the substitute extends the lower temperature limit to -65°C, providing broader thermal coverage if required by application specifications.

Contact material differs between the parts: the main part uses phosphor bronze, while the substitute uses copper alloy. Both materials are tin-plated and suitable for solder termination. The substitute part specifies a 3A current rating, whereas the main part does not provide this specification.

For new designs or applications requiring long-term component availability, the TSW-133-07-T-D is the preferred selection. The 4-103328-5 substitute is applicable only when the increased position count (80 vs. 66) aligns with circuit requirements and obsolescence risk is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 4-103328-5 (80-position) be used as a direct replacement for the TSW-133-07-T-D (66-position)?

A: Direct replacement is not recommended. While both connectors share identical pitch (0.100"), row spacing, mounting type, and fastening mechanism, the 80-position variant has a larger footprint. PCB layout modifications would be required. Use the 80-position part only when the additional 14 contact positions are functionally necessary.

Q: What are the key compatibility criteria for these connectors?

A: Compatibility is determined by: mating pitch (0.100"), number of rows (2), connector type (header with male pins), mounting method (through-hole), termination process (solder), and fastening type (push-pull). These parameters must remain constant for mechanical and electrical compatibility.

Q: Does the substitute part's Obsolete status affect its use?

A: Obsolete status indicates the manufacturer no longer actively produces the part. While existing inventory may be available, future sourcing cannot be guaranteed. For new designs or long-term production, the Active status TSW-133-07-T-D is the appropriate choice.

Q: Are there differences in contact post length between these parts?

A: Yes. The TSW-133-07-T-D has a 0.100" (2.54mm) contact post length, while the 4-103328-5 has 0.120" (3.05mm). This 0.020" difference may affect PCB trace routing and component placement in space-constrained layouts.

Q: What is the significance of the contact material difference?

A: The main part uses phosphor bronze contacts; the substitute uses copper alloy. Both are tin-plated and suitable for solder termination. Phosphor bronze typically offers superior spring characteristics and contact reliability, while copper alloy provides cost efficiency. For critical applications, the phosphor bronze specification of the main part is preferred.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, and have MSL 1 (Unlimited) moisture sensitivity levels. The substitute part extends the operating temperature range to -65°C, providing broader thermal coverage than the main part's -55°C minimum.
