TSW-108-23-F-D Equivalent & Substitute Parts

Part Overview

The TSW-108-23-F-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 16-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 and full RoHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-108-23-F-D is determined by strict alignment of the following critical parameters:

• Connector type classification (Header with male pin contacts)
• Position count and row configuration (16 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish specifications (Gold mating, Tin post)
• Shrouding configuration (Unshrouded)
• Style classification (Board to Board or Cable)

The substitute part 5-146256-8 (TE Connectivity AMP Connectors) meets all critical substitution criteria. Both parts share identical position counts, pitch specifications, mounting types, and contact configurations. Variations in secondary parameters such as insulation material composition, contact finish thickness, and operating temperature range do not preclude substitution when the primary electrical and mechanical interfaces remain compatible.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-108-23-F-D and 5-146256-8 maintain active product status with full RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific temperature requirements and insulation material compatibility.

The TSW-108-23-F-D supports an extended upper operating temperature of 125°C compared to the 5-146256-8 maximum of 105°C. Applications requiring sustained operation above 105°C necessitate the Samtec part. The TSW-108-23-F-D uses PBT insulation, while the 5-146256-8 employs LCP insulation; material selection may influence chemical resistance and mechanical properties in specific environments.

Both parts feature identical mating pitch, row spacing, contact configuration, and fastening mechanisms, ensuring mechanical and electrical compatibility at the interface level. The minor variation in post contact length (0.115" versus 0.120") falls within acceptable tolerance for standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-146256-8 directly replace the TSW-108-23-F-D in all applications?

A: Direct replacement is possible when the application operating temperature does not exceed 105°C. The TSW-108-23-F-D is required for applications operating above 105°C up to 125°C. Both parts share identical mating pitch, row spacing, contact count, and fastening specifications.

Q: What is the significance of the insulation material difference between PBT and LCP?

A: PBT (Polybutylene Terephthalate) and LCP (Liquid Crystal Polymer) are both thermoplastic materials with UL94 V-0 ratings. Material selection affects chemical resistance, dimensional stability, and mechanical properties. Application-specific environmental conditions determine which material is appropriate.

Q: Are the contact post length variations significant?

A: The post length difference of 0.005" (0.13mm) between the TSW-108-23-F-D (0.115") and 5-146256-8 (0.120") is minor and does not affect standard through-hole PCB assembly compatibility. Both lengths accommodate typical PCB thickness and solder joint formation.

Q: Do both parts support the same current and voltage ratings?

A: The provided specifications do not include current or voltage ratings for the TSW-108-23-F-D. The 5-146256-8 is rated for 3A. Application-specific electrical requirements must be evaluated against manufacturer datasheets for final selection.

Q: What packaging differences exist between these parts?

A: The TSW-108-23-F-D is supplied in Bag packaging, while the 5-146256-8 is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical performance and is determined by procurement and inventory requirements.

Q: Are both parts RoHS3 compliant?

A: Yes, both the TSW-108-23-F-D and 5-146256-8 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
