Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0878910106 is determined by the following critical parameters:

• Number of Positions and Rows: All substitute parts must maintain 1 position and 1 row configuration
• Mounting Type: All substitutes must support through-hole mounting
• Termination Method: All substitutes must use solder termination
• Connector Type: All substitutes must be header-type connectors
• Contact Material and Finish: Substitutes may vary in contact finish (tin or gold) and finish thickness, provided the base copper alloy material is maintained
• Overall Dimensions: Stack height, post length, and tail length may vary to accommodate different PCB spacing requirements
• Compliance Standards: All substitutes must maintain ROHS3 compliance and REACH unaffected status

The substitute parts listed below are manufactured by Samtec Inc. and belong to the Flex Stack series (DW and ZW families). These parts share the core functional characteristics of the Molex 0878910106 while offering variations in contact finish and dimensional specifications to support different application requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with the original Molex 0878910106.

Contact Finish Selection: The Molex 0878910106 features tin plating at 100.0µin thickness. Samtec DW-01-07-T-S-200 and ZW series tin-plated variants (ZW-01-07-T-S-200-115, ZW-01-07-T-S-200-140, ZW-01-07-T-S-268-110, ZW-01-09-T-S-200-430) provide tin-finish equivalents. Gold-plated alternatives (DW-01-07-G-S-200, ZW-01-08-G-S-270-230) are available for applications requiring enhanced corrosion resistance or specific contact performance characteristics.

Dimensional Compatibility: Substitute selection must account for PCB spacing and stacking requirements. The DW series (DW-01-07-G-S-200, DW-01-07-T-S-200) maintains a 0.200" stack height with post lengths near the original specification. The ZW series offers variable stack heights (0.200" to 0.270") and post lengths (0.030" to 0.115") to accommodate different board-to-board spacing configurations.

Moisture Sensitivity: The Molex 0878910106 carries MSL 1 (Unlimited). Samtec DW series parts are rated Not Applicable for MSL, while ZW series parts maintain MSL 1 (Unlimited) rating, matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute a Samtec part for the Molex 0878910106 in my existing design?

A: Yes, provided the substitute maintains 1-position, 1-row configuration with through-hole solder termination. Dimensional parameters (post length, stack height, tail length) must be compatible with your PCB layout and mating connector specifications. Verify contact finish requirements; tin-plated substitutes are functionally equivalent to the original tin-plated Molex part.

Q: What is the difference between tin and gold contact finishes?

A: The Molex 0878910106 uses tin plating at 100.0µin thickness. Tin-plated Samtec substitutes provide equivalent electrical performance for standard applications. Gold-plated alternatives (DW-01-07-G-S-200, ZW-01-08-G-S-270-230) offer enhanced corrosion resistance and are suitable for high-reliability or harsh environment applications. Gold finish thickness on Samtec parts is specified at 10.0µin.

Q: How do I select the correct Samtec ZW variant?

A: ZW series parts differ in post length and stack height. Select based on your PCB thickness and required spacing between the header and mating connector. ZW-01-07-T-S-200-115 provides 0.115" post length with 0.200" stack height. ZW-01-07-T-S-200-140 offers 0.090" post length with extended 0.140" tail. ZW-01-07-T-S-268-110 features increased 0.268" stack height with 0.052" post length. ZW-01-09-T-S-200-430 provides extended overall pin length (0.730") with 0.100" post length.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All listed Samtec substitutes maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original Molex 0878910106.

Q: What is the difference between DW and ZW series?

A: Both DW and ZW series are Samtec Flex Stack headers with 1-position configuration. DW series offers two variants: gold-plated (DW-01-07-G-S-200) and tin-plated (DW-01-07-T-S-200), both with 0.200" stack height and 0.110" tail length. ZW series provides greater dimensional flexibility with multiple post length and stack height combinations to accommodate various PCB spacing requirements.

Q: What inventory levels are available for substitute parts?

A: Samtec DW-01-07-T-S-200 has the highest availability at 2258 units. DW-01-07-G-S-200 has 1056 units. ZW series variants range from 620 to 1147 units. Verify current inventory status with your supplier before design finalization.
