Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0424910330 is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - mating (0.156" / 3.96mm)
• Number of positions (3)
• Number of rows (1)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 1 Wall)
• Fastening type (Friction Lock)
• Termination method (Solder)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The TE Connectivity AMP Connectors parts 3-644611-3 and 3-644615-3 meet all critical substitution criteria. Both parts are from the MTA-156 series and match the Molex KK396 series in functional electrical and mechanical specifications. The primary distinction between substitute options relates to contact material composition and insulation material properties, which do not affect interchangeability within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain active product status and full ROHS3 compliance, matching the Molex original part's regulatory standing. Selection between 3-644611-3 and 3-644615-3 depends on application-specific requirements not differentiated by the core substitution parameters. The 3-644615-3 includes board guide features, while 3-644611-3 does not. Both parts carry identical electrical ratings, flammability certifications, and environmental compliance designations. Inventory availability favors 3-644615-3 with 14,268 units in stock compared to 8,543 units for 3-644611-3.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity MTA-156 series connectors directly replace Molex KK396 series connectors?

A: Yes, when all critical parameters match. The 3-644611-3 and 3-644615-3 are direct functional equivalents to the 0424910330 based on connector type, pitch, position count, mounting method, shrouding, fastening mechanism, and termination specifications.

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

A: Both parts are electrically and mechanically equivalent. The 3-644615-3 includes board guide features; the 3-644611-3 does not. Contact material is copper alloy in both cases, and insulation material is thermoplastic glass-filled in both cases.

Q: Are there dimensional differences between the Molex and TE Connectivity parts?

A: Contact length specifications differ slightly. The Molex 0424910330 has an overall contact length of 0.720" (18.29mm) with post length of 0.140" (4.66mm). The TE Connectivity parts have overall contact length of 0.700" (17.78mm) with post length of 0.125" (3.18mm). Insulation height also differs: Molex at 0.446" (11.33mm) versus TE Connectivity at 0.545" (13.84mm).

Q: Do all three parts carry the same compliance certifications?

A: Yes. All three parts are UL94 V-0 rated, ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the voltage and current rating for these connectors?

A: The Molex 0424910330 does not specify voltage or current ratings in the provided data. The TE Connectivity substitutes specify 600VAC voltage rating and current rating that varies by wire gauge.
