Key Parameters

Substitute Part Grouping Explanation

Substitution of the 641151-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Rectangular Receptacle)
• Number of positions (4)
• Contact type (Female Socket)
• Pitch (0.156" / 3.96mm)
• Contact finish (Gold)
• Wire gauge compatibility (24 AWG)

Mechanical Compatibility Parameters:

• Cable termination method (IDC)
• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)
• Series designation (MTA-156)

Compliance Parameters:

• RoHS status
• Moisture Sensitivity Level (MSL)

The substitute part 3-641151-4 maintains identical electrical and mechanical specifications while differing in product status and RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: The 3-641151-4 is the appropriate selection for new applications. This part maintains active product status with TE Connectivity and carries RoHS compliance certification, meeting current regulatory requirements for electronic component procurement.

For Maintenance and Repair of Existing Equipment: The 641151-4 remains functionally equivalent to the 3-641151-4 for direct replacement in legacy systems. Both parts are electrically and mechanically identical across all critical parameters. Selection between these parts depends on application compliance requirements and inventory availability.

Compliance Considerations: Applications subject to RoHS directives or equivalent environmental regulations require the 3-641151-4. The 641151-4, classified as RoHS non-compliant, is suitable only for applications where such compliance is not mandated or for replacement in existing non-compliant systems.

Frequently Asked Questions (FAQ)

Q: Can the 3-641151-4 directly replace the 641151-4 in existing assemblies?

A: Yes. The 3-641151-4 is electrically and mechanically equivalent to the 641151-4. Both connectors share identical specifications for contact configuration, pitch, termination method, wire gauge, and mounting characteristics. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the primary difference between these two parts?

A: The primary differences are product status and RoHS compliance. The 641151-4 is obsolete and RoHS non-compliant, while the 3-641151-4 is active and RoHS compliant. All electrical and mechanical parameters are identical.

Q: Are there packaging differences between 641151-4 and 3-641151-4?

A: The 641151-4 is supplied in unspecified packaging, while the 3-641151-4 is supplied in bulk packaging. This distinction affects procurement and handling but does not impact connector performance or compatibility.

Q: Which part should be specified for new designs?

A: The 3-641151-4 should be specified for new designs. This part carries active product status and RoHS compliance, ensuring long-term availability and regulatory alignment.

Q: Is the MSL rating identical for both parts?

A: Yes. Both the 641151-4 and 3-641151-4 carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both parts support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) at 24 AWG wire gauge.
