Substitute Part Grouping Explanation

The PX0839/PC from Bulgin qualifies as a substitute for the A-RJ45DFR based on the following critical parameters:

Matching Core Specifications:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Number of Ports: 1
• Number of Rows: 1
• Orientation: Straight
• Termination: Solder
• Shielding: Shielded
• Ratings: Cat5e
• Contact Finish: Gold
• Tab Direction: User Selectable

Functional Equivalence: Both connectors are modular jack connectors designed for Ethernet applications with identical contact configurations and solder termination. The PX0839/PC maintains the same electrical and mechanical interface standards required for RJ45 connectivity.

Parameter Comparison

Engineering Selection Recommendations

The PX0839/PC from Bulgin is an active product with ROHS3 compliance, providing a viable alternative to the obsolete A-RJ45DFR. The substitute part maintains electrical and mechanical compatibility through identical contact configurations, solder termination, and Cat5e ratings.

The PX0839/PC offers enhanced environmental protection with IP68 ingress protection compared to the IP67 rating of the original part, and supports an extended operating temperature range of -40°C to 70°C versus -20°C to 60°C. These improvements provide greater design margin for demanding applications.

Both parts are classified under HTSUS 8536.69.4030 and carry EAR99 ECCN designation. The PX0839/PC's active product status ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: What makes the PX0839/PC a suitable substitute for the A-RJ45DFR?

A: Both connectors share identical core specifications: 8p8c (RJ45, Ethernet) jack configuration, solder termination, shielded design, Cat5e rating, and gold-plated contacts. These parameters define functional equivalence for modular Ethernet connector applications.

Q: Are there mechanical differences between these connectors?

A: The mounting flange design differs—the A-RJ45DFR uses a square flange while the PX0839/PC uses a bulkhead mount. Both are panel mount configurations suitable for standard panel cutout installations. Housing materials also differ: ABS versus PET/Polyester. These differences do not affect electrical performance or contact interface compatibility.

Q: Does the PX0839/PC provide better environmental protection?

A: The PX0839/PC is rated IP68 (dust tight, waterproof) compared to the A-RJ45DFR's IP67 rating. The substitute also supports a wider operating temperature range of -40°C to 70°C versus -20°C to 60°C, providing greater environmental tolerance.

Q: What compliance advantages does the PX0839/PC offer?

A: The PX0839/PC is ROHS3 compliant and carries active product status, ensuring regulatory alignment and ongoing manufacturer support. The A-RJ45DFR is obsolete, limiting future availability and technical support.

Q: Are contact materials interchangeable between these parts?

A: Both connectors feature gold-plated contacts with identical finish specifications. The A-RJ45DFR uses copper alloy base material while the PX0839/PC uses phosphor bronze. Both materials provide equivalent electrical conductivity and contact reliability for Ethernet applications.

Q: Can the PX0839/PC be used in existing A-RJ45DFR installations?

A: The PX0839/PC maintains electrical and mechanical compatibility through identical 8p8c contact configurations and solder termination. Panel mount installation requires verification of flange geometry compatibility with existing panel cutouts.
