Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76350-104-04LF is determined by strict alignment of the following critical parameters:

• Connector type: Header
• Contact type: Male pin
• Pitch spacing: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Position count: 4 positions in 2-row configuration
• Mounting: Through-hole, right-angle orientation
• Termination: Solder
• Contact shape: Square
• Contact material: Phosphor bronze
• Insulation material: Thermoplastic base (thermoplastic or PBT)
• Flammability: UL94 V-0
• RoHS compliance: Active status required

All four Samtec TSW series parts (TSW-102-08-G-D-RA, TSW-102-08-L-D-RA, TSW-102-08-S-D-RA, TSW-102-08-T-D-RA) meet these core substitution criteria. Variations in contact finish specifications (mating and post finishes) and operating temperature ranges represent secondary design considerations that do not affect mechanical or electrical interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four Samtec TSW-102 variants are active products with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the primary Amphenol ICC part. Selection among substitute options should be based on the following provided specifications:

TSW-102-08-G-D-RA: Gold mating finish (10.0µin thickness) with gold post finish. Operating temperature range -55°C to 125°C. Suitable for applications requiring consistent gold plating across mating and post surfaces.

TSW-102-08-L-D-RA: Gold mating finish (10.0µin thickness) with tin post finish. Operating temperature range -55°C to 125°C. Appropriate for cost-optimized designs where post finish material differs from mating surface.

TSW-102-08-S-D-RA: Gold mating finish (30.0µin thickness) with tin post finish. Operating temperature range -55°C to 125°C. Matches the mating finish thickness specification of the primary Amphenol ICC part while using tin post plating.

TSW-102-08-T-D-RA: Tin mating and post finishes. Operating temperature range -55°C to 105°C. Lowest operating temperature ceiling among substitute options. Suitable for applications not requiring gold contact surfaces.

Frequently Asked Questions (FAQ)

Q: Are all four Samtec TSW-102 variants mechanically interchangeable with the Amphenol ICC 76350-104-04LF?

A: Yes. All variants share identical pitch spacing (0.100" mating and row), position count (4 in 2 rows), mounting type (through-hole right-angle), contact shape (square), and contact material (phosphor bronze). Mechanical fit and board layout compatibility are equivalent.

Q: What is the significance of the contact finish differences between substitute parts?

A: Contact finish affects corrosion resistance and electrical performance in specific environments. Gold finishes provide superior corrosion resistance; tin finishes are cost-effective for standard applications. The mating finish thickness (10.0µin vs. 30.0µin) influences durability under repeated mating cycles. Post finish material affects solder joint reliability and long-term performance.

Q: Why do the Samtec parts have different operating temperature ranges?

A: TSW-102-08-T-D-RA specifies -55°C to 105°C, while the other three variants specify -55°C to 125°C. This difference is based on the material composition and finish specifications of each variant. Applications requiring operation above 105°C should use TSW-102-08-G-D-RA, TSW-102-08-L-D-RA, or TSW-102-08-S-D-RA.

Q: How do the insulation height differences affect compatibility?

A: The primary part specifies 0.200" (5.08mm) insulation height; all Samtec substitutes specify 0.219" (5.56mm). This 0.019" difference is within typical PCB design tolerances and does not affect mechanical interchangeability for standard board-to-board applications. Verify clearance in space-constrained designs.

Q: What is the difference between the post contact lengths?

A: The Amphenol ICC part specifies 0.120" (3.05mm) post length; all Samtec variants specify 0.090" (2.29mm). This 0.030" difference affects solder joint depth and may influence thermal performance in high-current applications. Verify solder pad design compatibility before substitution.

Q: Are all parts RoHS compliant?

A: Yes. The primary Amphenol ICC part is RoHS Compliant; all four Samtec substitutes are ROHS3 Compliant. Both designations meet current regulatory requirements for restricted substance elimination.

Q: What inventory levels are available for each part?

A: Amphenol ICC 76350-104-04LF: 666 pcs. Samtec TSW-102-08-G-D-RA: 1914 pcs. Samtec TSW-102-08-L-D-RA: 2866 pcs. Samtec TSW-102-08-S-D-RA: 2655 pcs. Samtec TSW-102-08-T-D-RA: 2862 pcs. All parts are listed as new original stock.
