Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 641150-2 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (2)
• Pitch (0.156" / 3.96mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)

Electrical Compatibility:

• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Wire type (Discrete or Ribbon Cable)
• Contact finish (Gold)
• Contact finish thickness (15.0µin / 0.38µm)

Environmental & Regulatory Compliance:

• RoHS compliance status
• MSL rating (1 - Unlimited)
• REACH status (REACH Unaffected)

The substitute part 3-641150-2 maintains identical specifications across all mechanical, electrical, and environmental parameters. The primary distinction is product status (Active vs. Obsolete) and packaging configuration (Bulk vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-641150-2 is functionally and mechanically equivalent to the 641150-2 across all critical parameters. The primary distinction is product lifecycle status: the original 641150-2 is obsolete, while 3-641150-2 maintains active production status.

Compliance Considerations:

Both parts satisfy RoHS and REACH regulatory requirements. The 641150-2 carries ROHS3 compliance designation, while 3-641150-2 carries RoHS compliance designation. Both designations confirm lead-free and restricted substance compliance applicable to this connector category.

Availability:

The 3-641150-2 substitute part is currently in active production with documented inventory availability (1109 pieces), whereas the 641150-2 is obsolete. For new designs, ongoing production, and field service applications, the 3-641150-2 is the appropriate selection to ensure supply chain continuity and long-term component availability.

Interchangeability:

The 3-641150-2 is a direct functional substitute. Mechanical fit, electrical performance, and environmental ratings are identical. No design modifications or qualification testing are required for substitution in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the 3-641150-2 be used as a direct replacement for the 641150-2 in existing designs?

A: Yes. The 3-641150-2 is mechanically and electrically identical to the 641150-2. All critical parameters including connector type, position count, pitch, mounting configuration, termination method, wire gauge, and contact specifications are equivalent. Direct substitution is supported without design modification.

Q: What is the difference between the 641150-2 and 3-641150-2 part numbers?

A: The primary difference is product status. The 641150-2 is obsolete, while the 3-641150-2 is in active production. The 3-641150-2 also specifies bulk packaging. All functional and electrical specifications are identical.

Q: Are there any compatibility concerns with IDC termination between these parts?

A: No. Both parts utilize identical IDC termination technology, wire gauge (22 AWG), and contact specifications. IDC tooling and termination procedures are interchangeable.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both parts are RoHS compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). Environmental and regulatory performance is equivalent.

Q: What is the pitch specification, and why is it important for substitution?

A: Both parts feature 0.156" (3.96mm) pitch, which defines the center-to-center spacing between connector positions. Pitch is a critical mechanical parameter that must match exactly for proper mating with corresponding plug connectors. Both parts are identical in this specification.

Q: Can these connectors accommodate both discrete and ribbon cable?

A: Yes. Both the 641150-2 and 3-641150-2 support discrete or ribbon cable termination via IDC technology. Wire gauge is specified at 22 AWG for both parts.

Q: What does the closed-end feature mean?

A: The closed-end design indicates that the connector housing includes a protective end cap or closure, providing strain relief and environmental protection at the cable termination point. Both parts incorporate this feature identically.
