Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 646486-1 are classified based on electrical and mechanical parameter equivalence. The substitution logic is structured as follows:

Direct Equivalent (Same Manufacturer): The 5646486-1 is a direct equivalent manufactured by TE Connectivity AMP Connectors. This part maintains identical electrical specifications, mechanical configuration, and connector geometry. The primary distinction is packaging format (Tube versus standard packaging) and RoHS compliance status (RoHS Compliant versus Not applicable).

Similar Equivalent (Alternative Manufacturer): The HM2R87PA8100N9LF, manufactured by Amphenol ICC (FCI), is classified as a similar equivalent. This part shares all critical electrical parameters and connector positioning specifications. The mounting type designation includes "Board Edge" in addition to through-hole configuration, and the connector series differs (Millipacs® versus Z-PACK). The contact finish, current rating, voltage rating, and operating temperature range remain identical.

Substitution Criteria: Parts qualify as substitutes when the following parameters match:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 176
• Pitch: 0.079" (2.00mm)
• Number of Rows: 8
• Connector Style: D 22
• Termination: Press-Fit
• Contact Finish: Gold, 30.0µin (0.76µm)
• Current Rating: 1.5 A
• Voltage Rating: 750Vrms
• Operating Temperature: -55°C to 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

646486-1 (Main Part): Select this part for applications requiring the Z-PACK series connector with standard packaging. This part is suitable for designs where RoHS compliance is not a requirement or where legacy component specifications are maintained.

5646486-1 (Direct Equivalent): This part is the preferred substitute when RoHS compliance is required. The 5646486-1 maintains identical electrical and mechanical specifications to the 646486-1 while providing RoHS Compliant certification. Tube packaging may require adjustment to assembly and handling procedures. This part is recommended for new designs or redesigns targeting RoHS-compliant bill of materials.

HM2R87PA8100N9LF (Similar Equivalent): This part is suitable for applications where Amphenol ICC (FCI) components are preferred or where supply chain diversification is required. The HM2R87PA8100N9LF provides ROHS3 Compliant certification and is supplied in Tray packaging. The Millipacs® series designation and Board Guide feature indicate this connector is optimized for board-edge mounting applications. This part maintains full electrical compatibility with the 646486-1 and is appropriate for designs requiring alternative manufacturer sourcing.

All three parts maintain identical electrical performance characteristics and are suitable for backplane connector applications operating within the specified voltage, current, and temperature parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5646486-1 be used as a direct replacement for the 646486-1?

A: Yes. The 5646486-1 is a direct equivalent with identical electrical and mechanical specifications. The primary differences are packaging format (Tube) and RoHS compliance status. No design modifications are required for substitution.

Q: What is the difference between the 646486-1 and HM2R87PA8100N9LF?

A: Both connectors share identical electrical specifications, position count, pitch, and termination method. The HM2R87PA8100N9LF is manufactured by Amphenol ICC (FCI) and belongs to the Millipacs® series, while the 646486-1 is a TE Connectivity Z-PACK connector. The HM2R87PA8100N9LF includes Board Edge mounting capability in addition to through-hole configuration and features a Board Guide rather than an Upper Shield.

Q: Are all three parts RoHS compliant?

A: The 646486-1 has RoHS status listed as Not applicable. The 5646486-1 is RoHS Compliant. The HM2R87PA8100N9LF is ROHS3 Compliant. For applications requiring RoHS compliance, select either the 5646486-1 or HM2R87PA8100N9LF.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (standard, Tube, or Tray) does not affect electrical or mechanical performance. Packaging selection is based on assembly process requirements, inventory management, and handling procedures.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the design accommodates the mounting type and packaging format. The 646486-1 and 5646486-1 are fully interchangeable. The HM2R87PA8100N9LF is interchangeable for through-hole applications; however, the Board Edge mounting capability and Board Guide feature may require design consideration for specific applications.

Q: What is the significance of the connector style designation D 22?

A: The D 22 designation indicates the physical form factor and contact arrangement of the connector. All three substitute parts share this designation, confirming mechanical compatibility and mating interface equivalence.

Q: Are there any temperature or voltage limitations when substituting these parts?

A: No. All three parts maintain identical operating temperature range (-55°C to 125°C) and voltage rating (750Vrms). Substitution does not introduce any thermal or electrical limitations.

Q: What does Moisture Sensitivity Level 1 (Unlimited) indicate?

A: MSL 1 (Unlimited) indicates that the connector has no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.
