Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5646956-2 is the direct active substitute for the obsolete 646956-2 model. Selection of the 5646956-2 is based on the following engineering criteria:

Product Status Alignment: The 5646956-2 maintains active product status, ensuring continued availability and manufacturing support. The 646956-2 obsolete status creates supply chain risk and limits procurement options.

Regulatory Compliance: The 5646956-2 achieves RoHS compliance, whereas the 646956-2 is RoHS non-compliant. The 5646956-2 is REACH unaffected, compared to the 646956-2 which is REACH affected. These compliance improvements align with current regulatory requirements for electronic components.

Electrical and Mechanical Equivalence: The 5646956-2 maintains complete equivalence across all connector specifications including connector type, style, position count, mounting configuration, termination method, contact finish, and flammability rating. The substitute provides additional rated specifications: 250V voltage rating and -55°C to 125°C operating temperature range.

Packaging and Inventory: The 5646956-2 is supplied in tube packaging with 1,310 units in stock, compared to the 646956-2 which is available in limited quantities as obsolete inventory.

Frequently Asked Questions (FAQ)

Q: Can the 5646956-2 be used as a direct replacement for the 646956-2 in existing designs?

A: Yes. The 5646956-2 is electrically and mechanically equivalent to the 646956-2 across all specified parameters. Both components feature identical connector type, blade power style, 6-position configuration, board edge right-angle mounting, press-fit termination, gold or gold-palladium contact finish, and UL94 V-0 flammability rating. The 5646956-2 is a direct substitute suitable for board-level replacement without design modification.

Q: What are the key differences between the 646956-2 and 5646956-2?

A: The primary differences are product status and compliance certifications. The 646956-2 is obsolete and RoHS non-compliant with REACH affected status. The 5646956-2 is active, RoHS compliant, and REACH unaffected. Additionally, the 5646956-2 provides specified electrical ratings (250V) and operating temperature range (-55°C to 125°C), whereas these specifications are not provided for the 646956-2.

Q: Are there packaging differences between these parts?

A: Yes. The 646956-2 packaging specification is not provided in the available data. The 5646956-2 is supplied in tube packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 646956-2 and 5646956-2 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts classified under the same HTSUS and ECCN codes?

A: Yes. Both the 646956-2 and 5646956-2 share identical HTSUS code 8536.69.4040 and ECCN classification EAR99, confirming their equivalent commodity classification for trade and export purposes.

Q: What termination method is used for these connectors?
