Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0879371602 is determined by strict alignment of the following critical parameters:

Core Compatibility Parameters:

• Number of Positions: 16
• Pitch: 0.100" (2.54mm)
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Color: Black
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Mechanical Dimensions (Allowed Variance):

• Length - Overall Pin
• Length - Post (Mating)
• Length - Stack Height
• Length - Tail

Contact Finish Considerations:

• Primary substitute (ZW-16-08-T-S-312-055): Tin finish, matching the main part
• Secondary substitute (ZW-16-08-S-S-210-125-LL): Gold finish, alternative for enhanced corrosion resistance

Both substitute parts are manufactured by Samtec Inc. and belong to the Flex Stack ZW series, meeting all core electrical and mechanical compatibility requirements for 16-position 0.100" pitch through-hole header applications.

Parameter Comparison

Engineering Selection Recommendations

Samtec ZW-16-08-T-S-312-055 (Primary Substitute): This part provides the closest functional match to the Molex 0879371602, with identical tin contact finish and solder termination. Both parts maintain ROHS3 compliance and MSL 1 rating. Mechanical dimensions differ in stack height (0.312" vs. 0.343") and post mating length (0.163" vs. 0.085"), which may require PCB layout verification for specific applications. This substitute is suitable for direct replacement in applications where the dimensional differences are accommodated by the design.

Samtec ZW-16-08-S-S-210-125-LL (Secondary Substitute): This part offers gold contact finish as an alternative to tin, providing enhanced corrosion resistance in demanding environments. The kinked pin termination and reduced stack height (0.210") represent significant mechanical differences from the original part. This substitute is appropriate for applications requiring superior contact durability or where the reduced stack height provides design advantages. The gold finish thickness (30.0µin) differs from the tin finish thickness (100.0µin) of the main part.

Both substitutes are active products from Samtec Inc., ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the Samtec ZW-16-08-T-S-312-055 be used as a direct replacement for the Molex 0879371602?

A: Both parts share identical electrical specifications: 16 positions, 0.100" pitch, single row, through-hole mounting, and solder termination with tin contact finish. Mechanical dimensions differ, particularly in stack height and post mating length. Direct replacement is possible if the PCB layout and mating component clearances accommodate these dimensional variations.

Q: What is the difference between the two Samtec substitutes?

A: The primary difference is contact finish: ZW-16-08-T-S-312-055 uses tin finish matching the original part, while ZW-16-08-S-S-210-125-LL uses gold finish. Additionally, the gold-finish variant has a reduced stack height (0.210" vs. 0.312") and kinked pin termination. Contact finish thickness also differs: tin at 100.0µin (original) versus gold at 30.0µin (secondary substitute).

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting modern environmental and reliability standards.

Q: Which substitute should I select for a new design?

A: Selection depends on specific application requirements. Use ZW-16-08-T-S-312-055 for tin finish compatibility and closest dimensional match. Use ZW-16-08-S-S-210-125-LL if gold finish corrosion resistance or reduced stack height provides design benefits.

Q: Do the mechanical dimension differences affect PCB layout?

A: Yes. The stack height and post mating length differ between parts. Verify that mating components, PCB clearances, and connector retention mechanisms accommodate the dimensional specifications of the selected substitute before finalizing the design.

Q: Are these parts suitable for high-reliability applications?

A: All three parts are active products with ROHS3 compliance and MSL 1 rating. Compliance certifications and product status indicate suitability for standard industrial and commercial applications. Specific high-reliability requirements should be evaluated against detailed application specifications.
