Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-136-08-G-D-RA is determined by alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Number of Rows: 2 — determines board layout footprint
• Mounting Type: Through Hole, Right Angle — establishes PCB assembly method
• Contact Type: Male Pin — defines mating interface
• Termination: Solder — specifies connection method
• Connector Type: Header — functional classification
• Material Flammability Rating: UL94 V-0 — safety compliance requirement

The substitute part 9-103801-0 (TE Connectivity AMP Connectors) maintains these core parameters. Variations in position count (80 vs. 72), insulation height, contact finish thickness, and operating temperature range represent acceptable engineering tolerances within the rectangular connector category, provided the application does not require the specific thermal or dimensional constraints of the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-136-08-G-D-RA and 9-103801-0 maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends on application-specific requirements:

The TSW-136-08-G-D-RA supports a higher maximum operating temperature (125°C vs. 105°C) and maintains a lower minimum operating temperature (-55°C vs. -65°C), making it suitable for applications requiring the full -55°C to 125°C thermal envelope.

The 9-103801-0 provides 80 positions versus 72, offering additional contact capacity. The higher contact finish thickness on the mating surface (30.0µin vs. 10.0µin) may provide enhanced durability in high-cycle mating applications. The specified 3A current rating provides explicit electrical performance data.

Both parts feature identical pitch (2.54mm), row spacing (2.54mm), contact length dimensions, and mounting configuration, ensuring mechanical interchangeability at the board level. Inventory availability (931 units for TSW-136-08-G-D-RA; 973 units for 9-103801-0) supports both sourcing options.

Frequently Asked Questions (FAQ)

Q: Can the 9-103801-0 directly replace the TSW-136-08-G-D-RA in existing designs?

A: Direct replacement requires verification that the application does not depend on the specific 72-position configuration or the -55°C to 125°C operating range. The 80-position layout of the 9-103801-0 occupies additional board space. If the design uses all 72 positions of the original part, the extra 8 positions on the substitute may require PCB layout modification or remain unused.

Q: What is the significance of the different contact finish thicknesses?

A: The TSW-136-08-G-D-RA specifies 10.0µin (0.25µm) gold plating on mating contacts, while the 9-103801-0 specifies 30.0µin (0.76µm). Thicker plating generally provides improved wear resistance in high-cycle mating applications and enhanced corrosion protection. The thinner plating of the original part is sufficient for standard board-to-board or cable connections with moderate mating cycles.

Q: Are there temperature limitations when substituting these parts?

A: The TSW-136-08-G-D-RA operates from -55°C to 125°C, while the 9-103801-0 operates from -65°C to 105°C. Applications requiring operation above 105°C must use the original TSW-136-08-G-D-RA. Applications requiring operation below -55°C must use the 9-103801-0. Standard room-temperature applications fall within both ranges.

Q: What is the difference between the insulation materials?

A: The TSW-136-08-G-D-RA uses Polybutylene Terephthalate (PBT), while the 9-103801-0 uses Thermoplastic. Both materials meet UL94 V-0 flammability requirements. PBT offers superior chemical resistance and dimensional stability; thermoplastic materials provide general-purpose insulation performance. Material selection does not affect mechanical compatibility for standard applications.

Q: Do both parts have the same solder termination compatibility?

A: Yes. Both parts feature solder termination with identical contact post dimensions (0.090" / 2.29mm). PCB pad layouts and reflow profiles remain compatible between the two parts.

Q: What does the breakaway feature on the 9-103801-0 mean?

A: The breakaway designation indicates that individual connector sections can be separated from the main assembly. This feature does not affect compatibility with the TSW-136-08-G-D-RA in applications where the connector is used as a complete unit.
