Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0430610021 are qualified based on the following critical parameters:

• Connector Type: Receptacle housing
• Number of Positions: 10
• Pitch: 0.156" (3.96mm)
• Contact Type: Female Socket
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Color: Natural
• RoHS3 Compliance: Required

The TE Connectivity AMP Connectors part 1-640251-0 meets all these core electrical and mechanical requirements, making it a direct substitute for the Molex 0430610021 in applications requiring 10-position rectangular connector housings with 3.96mm pitch spacing.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0430610021 and TE Connectivity 1-640251-0 are Active products with ROHS3 compliance and MSL 1 ratings. The TE Connectivity part provides an extended operating temperature range (-55°C to 105°C) compared to the Molex part (0°C to 75°C), offering broader thermal performance capability. Both parts feature identical electrical and mechanical specifications for the 10-position, 3.96mm pitch receptacle housing configuration. Selection between these parts should be based on application-specific temperature requirements and component availability.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-640251-0 directly replace the Molex 0430610021?

A: Yes. Both parts share identical connector type, position count, pitch, mounting configuration, and contact termination specifications. They are mechanically and electrically compatible for receptacle housing applications.

Q: What is the difference in insulation material between these parts?

A: The Molex 0430610021 uses Polyester with glass filling, while the TE Connectivity 1-640251-0 uses Polyamide (PA) Nylon. Both materials meet the required RoHS3 compliance and MSL 1 ratings for this application category.

Q: Does the extended temperature range of the TE Connectivity part affect compatibility?

A: No. The TE Connectivity part's extended operating range (-55°C to 105°C) is a performance advantage and does not impact mechanical or electrical compatibility with standard applications operating within the Molex part's range (0°C to 75°C).

Q: Are contacts included with these connector housings?

A: No. Both the Molex 0430610021 and TE Connectivity 1-640251-0 are housings only. Contacts must be sourced separately and are not included with these parts.

Q: What certifications apply to both parts?

A: Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity ratings, and maintain Active product status with full regulatory compliance.
