• Operating temperature range: -55°C ~ 125°C
• Contact finish: Gold or Gold-Palladium
• Material flammability rating: UL94 V-0

Mechanical Compatibility Parameters:

• Mounting type: Board Edge, Through Hole, Right Angle
• Termination type: Press-Fit
• Contact layout: 6 Power
• Color: Gray
• Moisture sensitivity level: 1 (Unlimited)

Series Designation:

• Both parts belong to the UPM (Universal Power Modules) series

The substitute part 5646956-1 maintains full electrical and mechanical compatibility with the main part 646956-1 across all specified parameters. Both parts are manufactured by TE Connectivity AMP Connectors and are classified as active products.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The substitute part 5646956-1 is electrically and mechanically equivalent to the main part 646956-1 across all specified connector parameters. Both parts maintain identical electrical ratings, mechanical mounting configurations, and thermal operating ranges.

Compliance Considerations:

The substitute part 5646956-1 offers improved regulatory compliance status compared to the main part 646956-1. The substitute part is ROHS3 compliant and REACH unaffected, whereas the main part is RoHS non-compliant and REACH affected. For applications subject to RoHS3 or REACH regulatory requirements, the substitute part 5646956-1 is the appropriate selection.

Current Rating:

The main part 646956-1 specifies a current rating of 10A. The substitute part 5646956-1 does not provide a specified current rating in the available documentation. For applications where the 10A current rating is a critical design parameter, the main part 646956-1 should be selected if this specification is required.

Inventory Availability:

Both parts are active products with current stock availability. The main part 646956-1 has 957 pieces in stock, while the substitute part 5646956-1 has 941 pieces in stock.
