Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0010891806 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Number of positions: 80
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Connector type: Header, Breakaway
• Contact type: Male Pin
• Mounting type: Through Hole, Right Angle
• Termination: Solder
• Fastening type: Push-Pull
• Shrouding: Unshrouded
• Style: Board to Board or Cable

Secondary Compatibility Parameters:

• Contact finish - mating: Gold
• Material flammability rating: UL94 V-0
• Insulation color: Black
• Moisture sensitivity level: 1 (Unlimited)

The TE Connectivity AMP Connectors part number 4-103326-0 (AMPMODU Mod II series) meets all primary substitution criteria and maintains compatibility across secondary parameters, establishing it as a direct functional equivalent for the obsolete Molex 0010891806.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0010891806 and TE Connectivity 4-103326-0 are classified as obsolete products. Selection between these components should be based on the following engineering considerations:

Compliance and Regulatory Status: Both parts carry identical RoHS non-compliant and REACH unaffected designations, with matching ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Neither part offers compliance advantages over the other from a regulatory standpoint.

Physical and Electrical Compatibility: The parts maintain functional equivalence across all critical mating parameters: 80-position, 2-row configuration at 0.100" (2.54mm) pitch with identical row spacing. Both employ push-pull fastening, solder termination, and gold-plated mating contacts at 15.0µin thickness. The minor variations in contact length (0.240" vs. 0.230" mating; 0.110" vs. 0.120" post) and insulation height (0.200" vs. 0.238") fall within acceptable mechanical tolerances for board-to-board and cable applications.

Material and Thermal Considerations: The TE Connectivity part specifies an operating temperature range of -65°C to 105°C and a current rating of 3A, whereas the Molex part does not provide these specifications. For applications requiring defined thermal or current performance, the TE Connectivity part offers documented electrical characteristics. The contact material difference (Phosphor Bronze vs. Copper Alloy) and insulation material difference (Polyester, Glass Filled vs. Thermoplastic) do not preclude substitution but should be evaluated against specific application requirements.

Inventory and Availability: Current inventory shows 866 units of the Molex part and 897 units of the TE Connectivity part available as new original stock.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-103326-0 be used as a direct replacement for the Molex 0010891806?

A: Yes. Both parts share identical critical parameters: 80 positions, 2 rows, 0.100" (2.54mm) pitch, right-angle through-hole mounting, push-pull fastening, and solder termination. The minor dimensional variations in contact length and insulation height are within acceptable mechanical tolerances for standard board-to-board and cable interconnect applications.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Contact finish on posts: Tin vs. Tin-Lead; (2) Contact material: Phosphor Bronze vs. Copper Alloy; (3) Insulation material: Polyester, Glass Filled vs. Thermoplastic; (4) Documented operating temperature and current rating provided only for the TE Connectivity part (-65°C to 105°C, 3A). These differences do not affect mating compatibility or basic electrical function.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical RoHS non-compliant status, REACH unaffected designation, EAR99 ECCN classification, and 8536.69.4040 HTSUS code. Neither part offers regulatory compliance advantages over the other.

Q: What should I consider when selecting between these two obsolete parts?

A: Selection should be based on: (1) Application operating temperature requirements—the TE Connectivity part specifies -65°C to 105°C operation; (2) Current requirements—the TE Connectivity part specifies 3A rating; (3) Material compatibility with your specific application environment; (4) Current inventory availability and lead times from your supplier.

Q: Are the dimensional differences significant for PCB layout?

A: The dimensional variations are minor: contact length mating difference of 0.010" (0.26mm) and insulation height difference of 0.038" (0.97mm). These differences are typically accommodated within standard PCB design tolerances for through-hole connector footprints. Verify your specific PCB layout requirements against both datasheets if dimensional precision is critical to your application.

Q: Can I mix Molex and TE Connectivity connectors in the same system?

A: Yes, provided they are mated to compatible receptacles. Both parts are male pin headers with identical pitch and row spacing. Ensure that the mating receptacles are designed for 0.100" (2.54mm) pitch, 80-position, 2-row configuration with push-pull fastening.
