Molex 0026192041 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0026192041 is a vertical rectangular connector header designed for through-hole mounting applications. This 4-position connector operates at a 0.156" (3.96mm) pitch and features shrouded design with solder termination. The part is actively produced and widely used in automotive, industrial, medical, and telecommunications applications. Equivalent parts may be required due to supply constraints, design revisions, or application-specific requirements where alternative connector series offer compatible electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0026192041 is determined by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) - must match exactly for PCB footprint compatibility
• Number of Positions: 4 - connector capacity requirement
• Number of Rows: 1 - single-row configuration
• Connector Type: Header - board-to-cable/wire interface
• Contact Type: Male Pin - mating interface specification
• Mounting Type: Through Hole - PCB assembly method
• Termination: Solder - electrical connection method
• Shrouding: Shrouded - 1 Wall - mechanical protection and alignment

The TE Connectivity AMP Connectors 644753-4 (MTA-156 series) meets all critical substitution criteria. Both connectors share identical pitch, position count, row configuration, contact type, mounting method, and termination approach. Mechanical dimensions show minor variations in contact length and insulation height, which remain within acceptable tolerances for standard board-to-cable applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0026192041 and TE Connectivity 644753-4 are active products with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and environmental regulatory adherence. The TE Connectivity 644753-4 provides enhanced material flammability performance (UL94 V-0 versus V-2) and documented operating temperature range (-55°C ~ 105°C) with specified voltage rating (600VAC), making it suitable for applications requiring higher thermal and electrical performance specifications. The Molex 0026192041 remains the primary specification; the TE Connectivity alternative is electrically and mechanically compatible for board-to-cable applications where the documented performance parameters of the substitute meet or exceed application requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 644753-4 be used as a direct replacement for the Molex 0026192041?

A: Yes, for standard board-to-cable applications. Both connectors share identical pitch (0.156"), position count (4), row configuration (1), contact type (male pin), mounting method (through hole), and termination (solder). Minor dimensional variations in contact length and insulation height do not affect electrical or mechanical compatibility in typical applications.

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

A: The primary differences are contact material (brass versus copper alloy), insulation material composition (polyamide/nylon versus thermoplastic/glass-filled), and flammability rating (UL94 V-2 versus V-0). The TE Connectivity part provides documented operating temperature range and voltage rating specifications not listed for the Molex part.

Q: Are there any mechanical compatibility concerns?

A: The TE Connectivity 644753-4 has a slightly shorter overall contact length (0.700" versus 0.750") and greater insulation height (0.425" versus 0.359"). These differences are within standard tolerances for board-to-cable connector applications and do not create compatibility issues with standard mating connectors or PCB layouts designed for 0.156" pitch headers.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant with MSL 1 rating. The TE Connectivity part carries a higher flammability rating (UL94 V-0) compared to the Molex part (UL94 V-2), providing enhanced material performance for applications with stricter safety requirements.

Q: What fastening differences exist between these connectors?

A: The Molex 0026192041 uses push-pull fastening, while the TE Connectivity 644753-4 uses friction lock fastening. Both methods provide secure mating; selection depends on application-specific requirements for connector retention and mating force.
