TSW-112-08-G-S-RA Equivalent & Substitute Parts

Part Overview

The TSW-112-08-G-S-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 12-position connector operates at 0.100" (2.54mm) pitch and features gold-plated phosphor bronze contacts with solder termination. The part maintains active product status and is RoHS3 compliant with UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct functional replacement in applications where position count flexibility or alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-112-08-G-S-RA 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
• Mounting Type: Through hole, right angle configuration
• Termination: Solder termination
• Contact Finish - Mating: Gold plating
• Shrouding: Unshrouded design
• Style: Board to board or cable application

The identified substitute part 4-103765-0 (TE Connectivity AMP Connectors) shares the core electrical and mechanical parameters required for functional equivalence. However, differences exist in position count (40 vs. 12), insulation material composition, contact finish thickness specifications, and product status classification. These differences must be evaluated against specific application requirements.

Engineering Selection Recommendations

The TSW-112-08-G-S-RA maintains active product status with full RoHS3 compliance and is the preferred selection for new designs and applications requiring regulatory adherence. The part's operating temperature range of -55°C to 125°C and UL94 V-0 flammability rating support demanding industrial and commercial environments.

The substitute part 4-103765-0 carries obsolete product status and RoHS non-compliance classification. This part is not suitable for applications subject to RoHS3 regulatory requirements or long-term supply chain planning. The 40-position configuration introduces mechanical incompatibility with designs specified for 12-position headers, requiring circuit board redesign and connector housing modifications. The narrower operating temperature range (-65°C to 105°C upper limit) and tin-lead post finish present additional constraints for high-temperature applications.

Selection of 4-103765-0 is limited to legacy system maintenance, repair of existing installations, or applications where RoHS compliance is not mandated and position count flexibility is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 4-103765-0 directly replace the TSW-112-08-G-S-RA in existing designs?

A: Direct replacement is not possible. The 4-103765-0 features 40 positions versus the 12-position configuration of the TSW-112-08-G-S-RA. Mechanical compatibility requires identical position counts. Circuit board layouts and connector housings designed for 12-position headers cannot accommodate 40-position connectors without redesign.

Q: What are the compliance implications of selecting the substitute part?

A: The 4-103765-0 is RoHS non-compliant and carries obsolete product status. Applications subject to RoHS3 regulatory requirements, EU market distribution, or corporate procurement policies mandating RoHS compliance cannot use this substitute. The TSW-112-08-G-S-RA is the compliant alternative.

Q: Are the contact finishes equivalent between these parts?

A: Contact finish specifications differ. The TSW-112-08-G-S-RA features 10.0µin (0.25µm) gold mating finish with gold post finish. The 4-103765-0 provides 30.0µin (0.76µm) gold mating finish with tin-lead post finish. These variations affect contact durability, corrosion resistance, and solderability characteristics.

Q: What is the operating temperature compatibility?

A: The TSW-112-08-G-S-RA operates across -55°C to 125°C. The 4-103765-0 operates across -65°C to 105°C. Applications requiring sustained operation above 105°C must use the TSW-112-08-G-S-RA. The substitute part's lower upper temperature limit restricts use in high-temperature environments.

Q: Are the insulation materials compatible?

A: Insulation materials differ. The TSW-112-08-G-S-RA uses Polybutylene Terephthalate (PBT), while the 4-103765-0 uses generic thermoplastic material. PBT provides superior chemical resistance and dimensional stability. The insulation height also differs: 0.119" (3.02mm) versus 0.138" (4.60mm), affecting board-level clearance and connector housing compatibility.

Q: What is the product availability status for each part?

A: The TSW-112-08-G-S-RA maintains active product status with 1088 pieces in stock. The 4-103765-0 is classified as obsolete with 899 pieces in stock. Active status ensures continued manufacturer support, design documentation updates, and long-term supply availability. Obsolete status indicates discontinued production and limited future availability.
