Substitute Part Grouping Explanation

Substitution for the SEAM8-20-S02.0-S-08-2 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 160-position, 8-row high-density array format
• Pitch and Spacing: 0.031" (0.80mm) pitch maintaining identical contact spacing
• Mounting Technology: Surface mount (SMD) compatibility
• Contact System: Gold finish at 30.0µin (0.76µm) thickness
• Physical Dimensions: Mated stacking height of 7mm and height above board of 0.179" (4.55mm)
• Mechanical Features: Board guide integration
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The substitute part SEAM8-20-S02.0-S-08-3 maintains full parametric equivalence across all these criteria, differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The SEAM8-20-S02.0-S-08-3 is the direct substitute for the obsolete SEAM8-20-S02.0-S-08-2. Both parts maintain identical electrical and mechanical specifications, ensuring drop-in compatibility for PCB designs and assembly processes.

The primary distinction is product status: SEAM8-20-S02.0-S-08-3 is actively manufactured and stocked, with 1504 units available in Cut Tape packaging. This active status ensures long-term supply chain availability and support.

Both parts carry ROHS3 compliance and MSL 1 rating, meeting current environmental and moisture handling requirements. The gold contact finish and specified thickness provide equivalent electrical performance and reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can SEAM8-20-S02.0-S-08-3 be used as a direct replacement for SEAM8-20-S02.0-S-08-2?

A: Yes. Both connectors are parametrically equivalent across all electrical and mechanical specifications, including position count, pitch, mounting type, contact finish, and physical dimensions. The substitute part is suitable for direct PCB design substitution and assembly compatibility.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. SEAM8-20-S02.0-S-08-2 is obsolete, while SEAM8-20-S02.0-S-08-3 is actively manufactured. SEAM8-20-S02.0-S-08-3 is supplied in Cut Tape (CT) packaging, whereas the original part's packaging is not specified.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance status and MSL 1 (Unlimited) moisture sensitivity rating. They meet the same environmental and handling standards.

Q: What is the base product number relationship?

A: Both SEAM8-20-S02.0-S-08-2 and SEAM8-20-S02.0-S-08-3 share the base product number SEAM8-20, indicating they belong to the same connector family within the SEARAY™ SEAM series.

Q: Are the physical dimensions identical?

A: Yes. Both connectors have identical mated stacking height (7mm) and height above board (0.179" / 4.55mm), ensuring compatibility with existing PCB layouts and mating connector designs.
