Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 646884-1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Number of positions: 125
• Pitch: 0.079" (2.00mm)
• Number of rows: 5
• Connector style: AB 25
• Termination method: Press-Fit
• Contact finish: Gold at 30.0µin (0.76µm)
• Current rating: 1.5 A minimum
• Operating temperature range: -55°C ~ 125°C minimum
• Moisture sensitivity level: 1 (Unlimited)

Mechanical Compatibility Parameters:

• Connector type: Header, Male Pins
• Mounting configuration: Through Hole, Right Angle
• All positions loaded

The substitute part HM2J65PE5110N9LF meets all critical electrical and mechanical parameters. The voltage rating of the substitute (750Vrms) exceeds the minimum requirement (500Vrms), providing additional design margin. Both parts maintain identical pitch, position count, row configuration, termination method, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TE Connectivity 646884-1 remains the primary selection when available. This part is active in production with established supply chain presence and 657 units in current inventory.

Substitute Part Selection: The Amphenol ICC HM2J65PE5110N9LF is a qualified substitute when the primary part is unavailable. This part meets all critical electrical and mechanical requirements with the following considerations:

Both parts are RoHS compliant and REACH affected, meeting current regulatory requirements. Both carry ECCN classification EAR99 for export control purposes. The substitute part's voltage rating of 750Vrms provides additional design margin compared to the primary part's 500Vrms specification. The substitute part is available in tray packaging with 1085 units in inventory, providing alternative sourcing availability.

The mounting designation difference (Board Edge vs. standard Through Hole) does not affect functional compatibility, as both configurations support right-angle through-hole mounting on printed circuit boards.

Frequently Asked Questions (FAQ)

Q: Can the HM2J65PE5110N9LF be used as a direct replacement for the 646884-1?

A: Yes. Both connectors share identical position count (125), pitch (2.00mm), row configuration (5), termination method (press-fit), current rating (1.5A), and operating temperature range (-55°C to 125°C). The substitute part meets all critical electrical and mechanical parameters required for functional equivalence.

Q: What is the difference between the mounting types listed for these connectors?

A: The primary part is specified as Through Hole, Right Angle. The substitute part is specified as Board Edge, Through Hole, Right Angle. Both configurations support right-angle mounting through printed circuit board holes. The Board Edge designation indicates the connector is designed for edge-mounted applications, which does not preclude standard through-hole mounting compatibility.

Q: Does the higher voltage rating of the substitute part affect compatibility?

A: No. The substitute part's 750Vrms rating exceeds the primary part's 500Vrms requirement. A higher voltage rating provides additional design margin and does not create incompatibility. The connector can be used in applications rated for 500Vrms or lower.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 646884-1 and HM2J65PE5110N9LF are RoHS compliant and REACH affected. Both carry identical ECCN classification (EAR99) for export control purposes. Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements.

Q: What is the difference in packaging between these parts?

A: The primary part (646884-1) packaging is not specified in available documentation. The substitute part (HM2J65PE5110N9LF) is supplied in tray packaging. Packaging differences do not affect connector functionality or electrical performance.

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

A: Yes. The connectors are mechanically and electrically interchangeable. Both support 125-position, 2.00mm pitch configurations with identical row counts and press-fit termination. No design modifications are required for substitution.

Q: What is the contact finish specification for both parts?

A: Both connectors feature gold contact finish at 30.0µin (0.76µm) thickness. This specification is identical across both parts, ensuring equivalent electrical contact characteristics and corrosion resistance.
