Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The part numbers 3-1241961-2, 6-1241961-2, 7-1241961-2, and 9-1241961-2 are direct functional equivalents to 4-1241961-3. All maintain identical electrical and mechanical specifications with PA-based insulation materials (PA6 or PA66 variants). These parts are RoHS Compliant or ROHS3 Compliant and operate within the required temperature range of -40°C to 105°C. Selection among these four options should be based on inventory availability and specific application requirements regarding insulation material composition.

Secondary Substitute (Extended Temperature Range):

Part numbers 5-928247-2 and 6-928247-2 provide extended operating temperature capability to 110°C maximum, offering additional thermal margin for applications requiring higher temperature performance. The 5-928247-2 variant features green color insulation, while 6-928247-2 maintains natural color. Both utilize PA-based insulation materials and are RoHS Compliant. These parts are suitable for applications where the extended temperature range provides operational advantage.

Compliance Considerations:

All substitute parts maintain RoHS compliance status. The 4-1241961-3 and 6-1241961-2 carry ROHS3 Compliant designation, while remaining substitutes are RoHS Compliant. Both compliance levels are acceptable for equivalent substitution. Moisture Sensitivity Level 1 (Unlimited) designation on primary substitutes indicates no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can 3-1241961-2 be used as a direct replacement for 4-1241961-3?

A: Yes. The 3-1241961-2 maintains identical electrical and mechanical specifications including 2-position configuration, 5.00mm pitch, crimp termination, and latch lock fastening. Both feature PA6 nylon 6 insulation and operate across the -40°C to 105°C temperature range. The primary difference is RoHS compliance designation, which does not affect functional interchangeability.

Q: What is the difference between the natural and green color variants?

A: Color designation (natural or green) is a cosmetic and identification feature only. The 5-928247-2 green variant and natural color variants (3-1241961-2, 6-1241961-2, 7-1241961-2, 9-1241961-2, 6-928247-2) are functionally equivalent. Color selection should be based on application identification requirements or customer specifications.

Q: Are PA6 and PA66 insulation materials interchangeable?

A: Yes, within the specified operating temperature range. Both PA6 (nylon 6) and PA66 (nylon 6/6) are polyamide variants that provide equivalent electrical and mechanical performance for this connector housing application. The 9-1241961-2 utilizes PA66 material while other substitutes use PA6 or PA variants. All operate within -40°C to 105°C range.

Q: Why do some substitutes have extended temperature range to 110°C?

A: Parts 5-928247-2 and 6-928247-2 are rated to -40°C to 110°C maximum, providing 5°C additional thermal margin compared to the 4-1241961-3 specification of -40°C to 105°C. This extended range does not affect compatibility; these parts are suitable for applications requiring higher temperature operation.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture sensitivity constraints. These parts do not require special moisture control during storage, handling, or assembly. The 6-928247-2 designation of "Not Applicable" for MSL carries equivalent meaning for this connector housing category.

Q: Can I substitute based on inventory availability alone?

A: No. Substitution must maintain all mandatory parameters: 2-position configuration, 5.00mm pitch, receptacle type with female socket contacts, free-hanging in-line mounting, crimp termination, and latch lock fastening. Inventory availability is a secondary consideration after confirming parameter compatibility.

Q: Are all listed substitutes currently in production?

A: Yes. All substitute parts listed carry Active product status, indicating current production availability from TE Connectivity AMP Connectors.
