Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 646957-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header, Male Blades
• Connector Style: Blade Power
• Number of Positions: 7
• Number of Rows: 1
• Mounting Type: Board Edge, Through Hole, Right Angle
• Termination: Press-Fit
• Contact Layout: 7 Power
• Contact Finish: Gold or Gold-Palladium
• Color: Gray
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99
• HTSUS Code: 8536.69.4040

The substitute part 5646957-1 meets all mandatory matching parameters. Differences exist only in packaging format (Bulk versus Tube), product compliance certifications (RoHS status and REACH status), and specified electrical ratings (Current Rating and Voltage Rating). These differences do not affect functional interchangeability in applications where the connector's core electrical and mechanical specifications are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

Both the 646957-1 and 5646957-1 connectors are active products from TE Connectivity AMP Connectors and are functionally equivalent for applications requiring a 7-position blade power header with board edge, through-hole, right-angle mounting.

Selection Criteria Based on Compliance Requirements:

The 5646957-1 substitute part is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to European Union environmental regulations and RoHS directives. The 646957-1 main part is RoHS non-compliant and should be selected only for applications where RoHS compliance is not a requirement.

Selection Criteria Based on Packaging:

The 646957-1 is supplied in Bulk packaging, while the 5646957-1 is supplied in Tube packaging. Packaging selection depends on manufacturing workflow requirements, inventory management practices, and handling procedures specific to the production environment.

Selection Criteria Based on Electrical Specifications:

The 5646957-1 provides specified electrical ratings of 250V and does not specify current rating. The 646957-1 specifies a 10A current rating and does not specify voltage rating. Selection between these parts should be based on the application's electrical requirements and the availability of complete specification data from the manufacturer.

Frequently Asked Questions (FAQ)

Q: Are the 646957-1 and 5646957-1 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 7-position configuration, board edge mounting, through-hole termination, right-angle orientation, and press-fit contact technology. They are mechanically interchangeable in applications where the mounting footprint and connector orientation are identical.

Q: What is the primary difference between these two part numbers?

A: The primary differences are packaging format (Bulk versus Tube), RoHS compliance status (non-compliant versus ROHS3 compliant), and specified electrical ratings. The 5646957-1 includes voltage rating specification (250V) and REACH compliance documentation, while the 646957-1 specifies current rating (10A).

Q: Can I use the 5646957-1 as a substitute for the 646957-1 in a design currently using the main part?

A: Substitution is possible if the application does not require RoHS non-compliance and if the 250V voltage rating of the 5646957-1 meets or exceeds the application's voltage requirements. Verify that the application's current requirements are compatible with the substitute part's specifications.

Q: Does packaging format affect connector performance or reliability?

A: No. Packaging format (Bulk versus Tube) does not affect connector performance, reliability, or electrical characteristics. Packaging selection is based on manufacturing and inventory management requirements only.

Q: Are both parts suitable for backplane applications?

A: Yes. Both the 646957-1 and 5646957-1 are classified as backplane connectors and are suitable for backplane applications requiring 7-position blade power headers with the specified mechanical and electrical characteristics.

Q: What is the significance of the UL94 V-0 flammability rating?

A: The UL94 V-0 rating indicates that the connector material meets UL94 vertical flame test requirements at the V-0 level, demonstrating superior flame resistance. This rating is identical for both parts and is maintained regardless of which substitute is selected.

Q: Does the MSL rating of 1 (Unlimited) apply to both parts?

A: Yes. Both the 646957-1 and 5646957-1 have an MSL rating of 1 (Unlimited), indicating that moisture sensitivity is not a limiting factor for storage or handling. No special moisture control measures are required for either part.
