Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0424910313 is determined by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical and electrical compatibility
• Number of Positions: 3 — connector must accommodate identical pin count
• Number of Rows: 1 — single-row configuration required
• Connector Type: Header — board-to-cable/wire interface
• Contact Type: Male Pin — pin gender must remain consistent
• Mounting Type: Through Hole — PCB mounting method must be identical
• Shrouding: Shrouded - 1 Wall — mechanical protection and keying alignment
• Fastening Type: Friction Lock — mating mechanism must be compatible
• Contact Shape: Square — cross-sectional geometry for proper seating
• Termination: Solder — connection method to PCB
• Material Flammability Rating: UL94 V-0 — regulatory compliance requirement

The TE Connectivity AMP Connectors part 3-644611-3 meets all critical substitution criteria and is qualified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0424910313 and TE Connectivity 3-644611-3 are active products with ROHS3 compliance and UL94 V-0 material flammability ratings. The connectors are functionally equivalent for applications requiring 3-position, 0.156" pitch through-hole headers with friction lock fastening.

Differences in contact finish (gold versus tin) and insulation material composition (polyester versus thermoplastic glass-filled) do not affect substitution eligibility when both parts meet the specified electrical and mechanical requirements for the intended application. Both parts maintain identical mating contact length and shrouded 1-wall configuration.

Selection between these parts should be based on inventory availability, lead time, and cost considerations, as both satisfy the core technical requirements for rectangular connector header applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-644611-3 be used as a direct replacement for the Molex 0424910313?

A: Yes. Both connectors share identical pitch (0.156"), position count (3), row configuration (1), mounting type (through hole), shrouding design (1 wall), and fastening mechanism (friction lock). Both are ROHS3 compliant and UL94 V-0 rated.

Q: What are the differences between these two connectors?

A: The primary differences are contact finish material (gold on Molex versus tin on TE Connectivity), contact base material (brass versus copper alloy), and insulation material composition (polyester versus thermoplastic glass-filled). These differences do not affect mechanical or electrical compatibility for standard applications.

Q: Are there any compatibility concerns with PCB layout or mating connectors?

A: No. Both connectors maintain identical mating contact length (0.450"), pitch spacing (0.156"), and shrouded geometry. Existing PCB layouts and mating connectors designed for the Molex 0424910313 are compatible with the TE Connectivity 3-644611-3.

Q: What packaging options are available?

A: Both parts are supplied in bulk packaging. Inventory availability differs: Molex 0424910313 has 741 pieces in stock, while TE Connectivity 3-644611-3 has 8543 pieces in stock.

Q: Are both parts suitable for automotive, industrial, and telecommunications applications?

A: The Molex 0424910313 is specified for automotive, general purpose, industrial, medical, and telecommunications applications. The TE Connectivity 3-644611-3 is specified for general purpose and industrial applications. Application suitability should be confirmed against specific end-use requirements.
