TSW-123-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-123-14-L-S is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 23-position, single-row connector operates across an extended temperature range of -55°C to 125°C and meets UL94 V-0 flammability requirements. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1). Alternative components may be required due to inventory constraints, application-specific position requirements, or design modifications necessitating different connector configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-123-14-L-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Contact Type: Male Pin — determines mating interface
• Mounting Type: Through Hole — establishes PCB assembly method
• Termination: Solder — specifies connection method
• Number of Rows: 1 — defines physical layout
• Connector Type: Header — functional classification
• Material Flammability Rating: UL94 V-0 — safety compliance requirement
• RoHS Status: ROHS3 Compliant — regulatory requirement

The substitute part 9-146274-0 shares the core electrical and mechanical characteristics (pitch, contact type, mounting, termination, row configuration, and flammability rating) but differs in position count (40 vs. 23), insulation material (LCP vs. PBT), contact finish composition, and operating temperature range. These differences establish it as a functional alternative for applications where the higher position count and alternative material properties are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-123-14-L-S and 9-146274-0 maintain active product status and meet identical regulatory compliance requirements (UL94 V-0, RoHS, REACH, MSL 1). Selection between these components depends on application-specific requirements:

The TSW-123-14-L-S provides a 23-position configuration with gold mating contact finish and operates across a wider temperature range (-55°C to 125°C). This configuration is suitable for applications requiring the specified position count and extended low-temperature performance.

The 9-146274-0 offers a 40-position configuration with breakaway capability, tin mating contact finish, and operates within -65°C to 105°C. The higher position count and breakaway feature accommodate applications requiring expanded connectivity options. The LCP insulation material provides enhanced dimensional stability compared to PBT.

Both components share identical pitch (2.54mm), contact type (male pin), mounting method (through hole), and termination (solder), establishing mechanical and electrical compatibility within their respective position configurations.

Frequently Asked Questions (FAQ)

Q: Can the 9-146274-0 directly replace the TSW-123-14-L-S in existing designs?

A: Direct replacement is not possible due to position count difference (40 vs. 23). The 9-146274-0 requires PCB layout modification to accommodate the additional 17 positions. However, the matching pitch (2.54mm), contact type (male pin), and mounting method (through hole) establish electrical and mechanical compatibility for redesigned applications.

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

A: Compatibility is established through: pitch matching (0.100" / 2.54mm), identical contact type (male pin), identical mounting method (through hole), identical termination (solder), single-row configuration, and matching flammability rating (UL94 V-0). Differences in position count, contact finish, and insulation material do not affect these core compatibility parameters.

Q: How do the operating temperature ranges differ?

A: The TSW-123-14-L-S operates from -55°C to 125°C, providing extended low-temperature capability. The 9-146274-0 operates from -65°C to 105°C, offering lower minimum temperature but reduced maximum temperature. Application requirements determine which range is appropriate.

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

A: The TSW-123-14-L-S features gold mating contact finish (10.0µin thickness), while the 9-146274-0 uses tin finish (100.0µin thickness). Gold provides superior corrosion resistance and lower contact resistance, while tin offers cost efficiency. Selection depends on environmental exposure and electrical performance requirements.

Q: Are both parts suitable for the same environmental conditions?

A: Both parts meet identical compliance standards (UL94 V-0, RoHS, REACH, MSL 1) and carry unlimited moisture sensitivity rating. Environmental suitability depends on specific operating temperature requirements and contact finish performance needs in the intended application environment.
