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

Part Overview

The TSW-117-07-S-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 is classified as an active product. The connector features unshrouded design with solder termination and push-pull fastening, suitable for board-to-board or cable interconnection in industrial and commercial applications. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in compatible designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the TSW-117-07-S-S is based on the following critical parameters that determine functional compatibility:

• Pitch - Mating: 0.100" (2.54mm) — determines PCB footprint and mating interface
• Connector Type: Header with Male Pin contacts — defines electrical interface
• Mounting Type: Through Hole — establishes board assembly method
• Termination: Solder — specifies connection method
• Contact Finish - Mating: Gold — ensures signal integrity and corrosion resistance
• Operating Temperature Range: -55°C ~ 125°C — defines environmental operating limits
• Material Flammability Rating: UL94 V-0 — establishes safety compliance

The identified substitute part 4-103239-0 (TE Connectivity AMP Connectors) shares the same mating pitch, connector type, mounting method, and termination approach. However, critical differences exist in position count, contact material composition, insulation material type, operating temperature range, and product status that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-117-07-S-S is an active product with ROHS3 compliance, making it the preferred choice for new designs and applications requiring current regulatory adherence. The substitute part 4-103239-0 is classified as obsolete with non-applicable RoHS status, indicating it is no longer in active production and does not meet current environmental compliance standards.

Selection between these parts must account for the following documented differences:

Position count differs significantly: the main part provides 17 positions while the substitute offers 40 positions. This difference affects PCB layout, connector footprint, and overall assembly dimensions.

Operating temperature ranges diverge: the main part operates from -55°C to 125°C, while the substitute operates from -65°C to 105°C. Applications requiring the upper temperature limit of 125°C cannot use the substitute part.

Contact material composition differs: phosphor bronze (main part) versus copper alloy (substitute), affecting mechanical properties and contact resistance characteristics.

Post contact finish differs: tin (main part) versus tin-lead (substitute), with implications for soldering processes and environmental compliance in lead-restricted applications.

For applications requiring active product status, current RoHS compliance, and the specified 17-position configuration with -55°C to 125°C operating range, the TSW-117-07-S-S remains the appropriate selection. The substitute part 4-103239-0 is suitable only for legacy system maintenance where obsolete component specifications are acceptable and regulatory compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can the 4-103239-0 substitute directly replace the TSW-117-07-S-S in new designs?

A: No. The substitute part is obsolete and does not meet ROHS3 compliance required for current designs. Additionally, the 40-position configuration differs from the 17-position main part, requiring different PCB layouts and assembly procedures.

Q: What is the primary compatibility factor between these connectors?

A: Both connectors share the same 0.100" (2.54mm) mating pitch, through-hole mounting method, solder termination, and push-pull fastening type. These parameters establish the fundamental interface compatibility at the connector level.

Q: Are there temperature limitations when considering substitution?

A: Yes. The main part operates from -55°C to 125°C, while the substitute operates from -65°C to 105°C. Applications requiring operation at temperatures above 105°C cannot use the substitute part.

Q: How do the contact materials differ between these parts?

A: The main part uses phosphor bronze contacts, while the substitute uses copper alloy contacts. This difference affects mechanical spring properties, contact resistance, and long-term reliability characteristics.

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

A: The main part is active and in current production with ROHS3 compliance certification. The substitute is obsolete and no longer manufactured, making it unsuitable for new designs and applications subject to environmental compliance regulations.

Q: Do both connectors have the same insulation material?

A: No. The main part uses Polybutylene Terephthalate (PBT), while the substitute uses a generic thermoplastic material. PBT provides superior thermal and chemical resistance properties.

Q: Can the 40-position substitute be used in applications designed for 17 positions?

A: No. The position count determines the connector footprint and mating interface. Using a 40-position connector in a 17-position application creates incompatibility at the PCB level and with mating connectors.
