AXC51F4040 Equivalent & Substitute Parts

Part Overview

The AXC51F4040 is a 40-position receptacle connector manufactured by Panasonic Electric Works, designed for surface mount applications with 0.016" (0.40mm) pitch mating contacts and gold plating. This connector is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity.

The primary reason for identifying substitute parts is the obsolete status of the AXC51F4040. Active alternatives ensure component availability, supply chain stability, and uninterrupted manufacturing operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXC51F4040 is evaluated based on the following critical parameters:

• Connector Type & Position Count: Both main and substitute parts must be 40-position receptacle connectors to maintain mechanical and electrical compatibility with mating plugs.
• Contact Finish: Gold plating on mating contacts is required for signal integrity and corrosion resistance.
• Mounting Type: Surface mount configuration is mandatory for PCB assembly compatibility.
• Termination Method: Solder termination ensures compatibility with existing assembly processes.
• Fastening Type: Detent lock mechanism must be present for secure mating.

The HD1S040HA1R6000 qualifies as a substitute based on these core parameters. However, the pitch specification differs (0.020" vs. 0.016"), which represents a mechanical incompatibility that must be evaluated in the context of the specific application and mating connector availability.

Engineering Selection Recommendations

The HD1S040HA1R6000 is an active product from JAE Electronics with RoHS compliance certification, providing supply chain continuity for the obsolete AXC51F4040. The substitute maintains core functional parameters including 40-position receptacle configuration, gold contact finish, solder termination, and detent lock fastening.

Key differences requiring evaluation:

• Pitch Specification: The substitute operates at 0.020" (0.50mm) pitch versus the original 0.016" (0.40mm). This difference necessitates verification that the mating plug connector is available in the 0.020" pitch specification or that the application can accommodate this change.
• Mounting Orientation: The substitute features right-angle mounting, whereas the original part mounting orientation is not specified. Confirm PCB layout compatibility.
• Voltage Rating: The substitute provides 100V rating versus the original 50V, offering improved electrical margin.
• Insulation Material: The substitute uses halogen-free plastic insulation, supporting environmental compliance requirements.

Selection of the HD1S040HA1R6000 is appropriate when the mating connector ecosystem supports 0.020" pitch and right-angle mounting orientation.

Frequently Asked Questions (FAQ)

Q: Can the HD1S040HA1R6000 directly replace the AXC51F4040 without PCB modifications?

A: Direct replacement requires that the mating plug connector is available in 0.020" (0.50mm) pitch specification. The pitch difference is a mechanical incompatibility that cannot be bridged without changing the mating connector. Additionally, the right-angle mounting orientation of the substitute may require PCB layout adjustments compared to the original part.

Q: What is the significance of the pitch difference between 0.016" and 0.020"?

A: Pitch defines the center-to-center spacing between adjacent contacts. A 0.016" pitch connector will not mate with a 0.020" pitch connector. Substitution is only viable if the corresponding mating connector is available in 0.020" pitch or if the application design can be modified to accommodate this change.

Q: Does the HD1S040HA1R6000 meet the same electrical specifications?

A: The substitute exceeds the original electrical specifications with a 100V rating versus 50V. Current rating per contact is not specified for the substitute but should be verified against application requirements. Both parts maintain gold contact finish for signal integrity.

Q: What packaging format is the substitute available in?

A: The HD1S040HA1R6000 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Is the substitute RoHS compliant?

A: Yes, the HD1S040HA1R6000 is RoHS compliant with halogen-free insulation material, supporting environmental and regulatory requirements.
