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

Part Overview

The TSW-117-07-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 17-position, single-row header operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The connector maintains an active product status with full inventory availability.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative connector configurations. The identified substitute part 4-103185-0 from TE Connectivity represents an alternative solution within the same connector family, though with differing position counts and specifications.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Insulation Material compatibility

Flexible Parameters (Position-Dependent):

• Number of Positions: May vary based on application requirements
• Contact Finish - Post: Alternative finishes acceptable if electrical performance maintained
• Operating Temperature range: Substitute must meet or exceed application requirements

The substitute part 4-103185-0 shares the core mating pitch, connector type, and contact configuration with the TSW-117-07-L-S. However, it differs in position count (40 vs. 17), product status (Obsolete vs. Active), and certain contact specifications. This part qualifies as a substitute only when position count flexibility exists in the design or when breakaway capability is required.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (TSW-117-07-L-S): This connector maintains active product status with full manufacturing support and availability. It is ROHS3 compliant and suitable for applications requiring long-term supply chain stability. The operating temperature range of -55°C to 125°C accommodates industrial and commercial applications. Selection of this part is recommended for new designs and applications requiring regulatory compliance assurance.

Substitute Part (4-103185-0): This part carries obsolete product status, indicating discontinued manufacturing and limited future availability. The substitute is not RoHS3 compliant, which may restrict use in regulated markets. The operating temperature upper limit of 105°C is lower than the primary part, making it unsuitable for high-temperature applications. The contact finish post material differs (tin-lead vs. tin), and the insulation material specification is less specific (thermoplastic vs. PBT). This substitute is applicable only when design flexibility permits higher position counts, breakaway functionality is required, and product status constraints are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 4-103185-0 directly replace the TSW-117-07-L-S in existing designs?

A: Direct replacement is not recommended. The substitute has 40 positions versus 17, requiring PCB layout modifications. The lower operating temperature maximum (105°C vs. 125°C) may not meet application requirements. The obsolete product status limits long-term availability.

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

A: Both connectors share 0.100" (2.54mm) mating pitch, male pin contact type, through-hole mounting, solder termination, and gold-plated mating contacts. These parameters enable mechanical and electrical compatibility at the contact interface level. Differences in position count, post length, insulation height, and contact material require design evaluation.

Q: Is the substitute suitable for high-temperature applications?

A: No. The substitute part operates to 105°C maximum, while the primary part operates to 125°C. Applications requiring the full -55°C to 125°C range must use the TSW-117-07-L-S.

Q: What is the significance of the product status difference?

A: The primary part (Active) has ongoing manufacturing support and guaranteed availability. The substitute (Obsolete) has discontinued production, limiting future procurement options and potentially affecting supply chain reliability.

Q: Are there RoHS compliance implications?

A: The primary part is ROHS3 compliant, meeting current regulatory requirements. The substitute shows "Not applicable" RoHS status, indicating it may not meet modern environmental compliance standards. Applications in regulated markets should use the primary part.

Q: How do the contact material differences affect performance?

A: The primary part uses phosphor bronze contacts; the substitute uses copper alloy. Both materials are suitable for 0.100" pitch headers with gold plating. The difference does not affect electrical performance for standard signal applications but may influence mechanical durability and cost.

Q: Can the substitute be used if only a subset of its 40 positions is needed?

A: Mechanically, yes. The connector can be populated with fewer contacts. However, this approach introduces design complexity and does not address the obsolete product status or lower operating temperature limit. The primary part remains the preferred choice for new designs.
