TSW-117-07-S-D Equivalent & Substitute Parts

Part Overview

The TSW-117-07-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 34-position, 2-row connector operates across a wide temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the TSW-117-07-S-D reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative connector configurations with compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-117-07-S-D is determined by the following critical parameters:

• Pitch and Row Spacing: 0.100" (2.54mm) mating pitch and row spacing are fundamental to mechanical compatibility
• Connector Type and Contact Type: Header configuration with male pins for board-to-board or cable applications
• Mounting and Termination: Through-hole solder termination required for PCB integration
• Contact Finish: Gold mating surface with tin post finish for electrical reliability
• Operating Temperature Range: Minimum -55°C to 125°C capability
• Compliance Standards: UL94 V-0 flammability rating and RoHS compliance status

The identified substitute part 4-103186-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares the core electrical and mechanical parameters necessary for functional equivalence, including identical pitch, row spacing, contact type, mounting method, and termination approach. However, critical differences exist in position count, product status, and compliance certifications that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-117-07-S-D maintains active product status with full RoHS3 compliance, making it the preferred choice for new designs and applications requiring regulatory compliance with modern environmental standards.

The 4-103186-0 substitute part carries obsolete product status and RoHS non-compliant designation. This part is suitable only for legacy system maintenance, repair, or replacement scenarios where the original connector specification must be preserved. The higher position count (80 vs. 34) and reduced upper operating temperature limit (105°C vs. 125°C) present additional constraints for direct substitution.

Key compliance differences include:

• TSW-117-07-S-D: ROHS3 Compliant, Active status
• 4-103186-0: RoHS non-compliant, Obsolete status

Applications requiring new component procurement, regulatory compliance, or extended temperature operation should prioritize the TSW-117-07-S-D. The 4-103186-0 is applicable only when legacy compatibility is the primary requirement and compliance constraints do not apply.

Frequently Asked Questions (FAQ)

Q: Can the 4-103186-0 directly replace the TSW-117-07-S-D in new designs?

A: No. The 4-103186-0 is obsolete and RoHS non-compliant, making it unsuitable for new product development. The TSW-117-07-S-D should be specified for all new applications.

Q: What are the critical compatibility parameters between these connectors?

A: Both connectors share identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), contact type (male pin), mounting method (through-hole), and termination approach (solder). These parameters establish the foundation for mechanical and electrical compatibility.

Q: Why does the 4-103186-0 have 80 positions while the TSW-117-07-S-D has 34?

A: These are distinct connector models designed for different application requirements. Position count is a primary design parameter that determines the connector's footprint and signal capacity. Direct substitution requires matching position count unless the application design is modified.

Q: What is the significance of the contact finish thickness difference?

A: The TSW-117-07-S-D features 30.0µin (0.76µm) gold plating on mating contacts, while the 4-103186-0 provides 15.0µin (0.38µm). Thicker plating generally provides enhanced durability and contact reliability over extended mating cycles.

Q: Are there temperature range limitations when considering substitution?

A: Yes. The TSW-117-07-S-D operates from -55°C to 125°C, while the 4-103186-0 operates from -65°C to 105°C. Applications requiring operation above 105°C cannot use the 4-103186-0 as a substitute.

Q: What does RoHS compliance status mean for component selection?

A: RoHS3 compliance (TSW-117-07-S-D) indicates the component meets current environmental regulations restricting hazardous substances. RoHS non-compliant components (4-103186-0) may face restrictions in certain markets and applications, particularly in consumer electronics and regulated industries.
