Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0424910312 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 2
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Shrouding: Shrouded - 1 Wall

Compliance Requirements:

• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts TE Connectivity AMP Connectors 3-644611-2 and 3-644615-2 meet all mandatory matching parameters and compliance requirements. Both parts are from the MTA-156 series and maintain full electrical and mechanical compatibility with the original Molex 0424910312 connector.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain full compliance with RoHS3 and UL94 V-0 flammability requirements. All three connectors are active products with unlimited moisture sensitivity ratings, ensuring long-term reliability in standard storage and operational environments.

The primary differences between the Molex 0424910312 and the TE Connectivity alternatives are contact post length (0.140" versus 0.125"), insulation height (0.446" versus 0.545"), contact finish material (gold versus tin), and base insulation material (polyester versus thermoplastic glass-filled). These dimensional and material variations do not affect mating compatibility at the 0.156" pitch specification.

Selection between 3-644611-2 and 3-644615-2 depends on application requirements. The 3-644615-2 includes a board guide feature, while the 3-644611-2 does not. Both parts are electrically and mechanically equivalent for standard through-hole board-to-cable applications.

Frequently Asked Questions (FAQ)

Q: Are the TE Connectivity parts fully compatible with the Molex 0424910312?

A: Yes. Both TE Connectivity parts (3-644611-2 and 3-644615-2) share identical mating pitch (0.156"), position count (2), row configuration (1), contact type (male pin), mounting method (through hole), and fastening mechanism (friction lock). Mating compatibility is assured.

Q: What is the difference between TE Connectivity 3-644611-2 and 3-644615-2?

A: The primary difference is the presence of a board guide feature on the 3-644615-2. Both parts are otherwise electrically and mechanically identical, with the same contact geometry, operating temperature range (-55°C ~ 105°C), and voltage rating (600VAC).

Q: Why do the contact post lengths differ between the Molex and TE Connectivity parts?

A: The Molex 0424910312 has a 0.140" post length, while both TE Connectivity alternatives have 0.125" post length. This 0.015" difference does not affect mating performance or board-level compatibility for standard through-hole solder applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. The Molex 0424910312 and both TE Connectivity substitute parts are ROHS3 compliant with UL94 V-0 flammability ratings.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Can I use these connectors in automotive applications?

A: The Molex 0424910312 is specified for automotive applications. The TE Connectivity alternatives are rated for general purpose and industrial applications. Application suitability should be confirmed against specific automotive qualification requirements.
