TSW-113-07-S-S Equivalent & Substitute Parts

Part Overview

The TSW-113-07-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 13-position, single-row header operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The connector is classified as Active product status and complies with ROHS3 and UL94 V-0 flammability standards. Identifying equivalent and substitute parts becomes necessary when the primary part 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-113-07-S-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Connector Type: Header with male pin contacts for board-to-board or cable applications
• Mounting Type: Through hole solder termination
• Contact Finish: Gold mating surface with tin post finish
• Operating Temperature Range: -55°C ~ 125°C minimum capability
• Material Flammability: UL94 V-0 compliance
• RoHS Compliance: ROHS3 or equivalent environmental standard

The substitute part 4-103185-0 (TE Connectivity AMP Connectors) shares the core electrical and mechanical parameters required for functional equivalence. However, critical differences exist in position count (40 vs. 13), contact finish thickness, operating temperature range, and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The TSW-113-07-S-S maintains Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. The substitute part 4-103185-0 is classified as Obsolete and carries no RoHS designation, indicating it does not meet current environmental compliance requirements for new designs.

Selection between these parts must account for the following factors:

• Position Count Mismatch: The substitute provides 40 positions versus the 13 positions of the main part. This fundamental difference requires circuit board redesign and connector footprint modification.
• Operating Temperature Range: The main part supports -55°C ~ 125°C operation, while the substitute operates only to -65°C ~ 105°C. Applications requiring the full upper temperature range of the main part cannot use the substitute.
• Contact Finish Thickness: The main part specifies 30.0µin (0.76µm) gold plating on mating contacts, compared to 15.0µin (0.38µm) on the substitute, affecting contact durability and mating cycle life.
• Post Finish Composition: The main part uses tin plating; the substitute uses tin-lead composition, which may introduce compatibility concerns in lead-free assembly environments.
• Compliance Status: The main part is ROHS3 compliant and Active; the substitute is Obsolete with undefined RoHS status, making it unsuitable for new product development or regulated applications.

For applications requiring direct functional equivalence with current compliance standards, the TSW-113-07-S-S is the appropriate selection. The substitute part 4-103185-0 is not recommended for new designs due to obsolete status and non-compliance with modern environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the 4-103185-0 substitute directly replace the TSW-113-07-S-S in existing designs?

A: Direct replacement is not possible. The substitute provides 40 positions compared to 13 positions in the main part, requiring complete circuit board redesign and connector footprint modification. Additionally, the substitute is classified as Obsolete with no RoHS compliance designation.

Q: What is the significance of the position count difference between these connectors?

A: Position count determines the number of signal or power connections the connector can accommodate. A 40-position connector cannot be used in applications designed for 13-position headers without substantial circuit redesign. The connectors are mechanically and electrically incompatible at the board level.

Q: Does the operating temperature range difference affect compatibility?

A: Yes. The main part TSW-113-07-S-S operates from -55°C to 125°C, while the substitute 4-103185-0 operates from -65°C to 105°C. Applications requiring operation above 105°C cannot use the substitute. The main part provides superior high-temperature performance.

Q: What does "Obsolete" product status mean for the substitute part?

A: Obsolete status indicates the part is no longer manufactured or supported by the vendor. Inventory may be available from distributors, but no future production is guaranteed. Obsolete parts are not recommended for new product designs or long-term applications requiring supply chain continuity.

Q: Are there compliance differences between these parts?

A: Yes. The TSW-113-07-S-S is ROHS3 compliant and carries Active product status, meeting current environmental and regulatory standards. The 4-103185-0 has undefined RoHS status and Obsolete classification, making it unsuitable for applications subject to environmental compliance requirements or regulated industries.

Q: What is the impact of contact finish thickness on connector performance?

A: Contact finish thickness affects mating cycle life, contact resistance stability, and durability. The main part specifies 30.0µin (0.76µm) gold plating, providing superior protection compared to the substitute's 15.0µin (0.38µm) specification. Thicker plating extends connector service life and maintains lower contact resistance over extended use.

Q: Why does the substitute use tin-lead post finish instead of tin?

A: The substitute part predates lead-free manufacturing requirements. Tin-lead composition may introduce compatibility concerns in lead-free assembly environments and may not meet RoHS compliance requirements for new applications. The main part's tin finish aligns with modern lead-free manufacturing standards.
