Key Parameters

Substitute Part Grouping Explanation

The Rosenberger 02K80F-40ML5 qualifies as a direct substitute for the 02K80A-40ML5 based on the following critical parameters:

Electrical Compatibility:

• Both connectors maintain 50 ohm impedance
• Identical frequency rating of 40 GHz maximum
• Matching voltage rating of 250 V
• Same mating cycle specification of 500 cycles
• Identical center contact material (Beryllium Copper) and gold plating

Mechanical Compatibility:

• Both are 2.92mm connector jacks with female socket configuration
• Surface mount termination method
• Identical dielectric material (PEEK)
• Matching operating temperature range (-40°C ~ 85°C)
• Same moisture sensitivity level (MSL 1)

Key Difference: The primary distinction between these parts is the mounting angle: the 02K80A-40ML5 features a right angle (90°) configuration, while the 02K80F-40ML5 provides a 45° angle mounting option. This angular difference allows the 02K80F-40ML5 to serve as a substitute in applications where space constraints or PCB layout requirements necessitate an alternative mounting geometry while maintaining full electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 02K80A-40ML5 and 02K80F-40ML5 are active production parts with full ROHS3 compliance and REACH affected status, ensuring regulatory alignment for current manufacturing standards. The selection between these parts should be determined by PCB layout requirements and connector orientation needs.

The 02K80A-40ML5 with right angle mounting is appropriate for applications requiring perpendicular signal routing from the PCB surface. The 02K80F-40ML5 with 45° angle mounting accommodates designs where intermediate angular orientation reduces mechanical stress or optimizes spatial efficiency within constrained enclosures.

Both parts carry identical electrical specifications, thermal ratings, and reliability metrics (500 mating cycles), confirming functional interchangeability within the specified operating envelope. The higher inventory availability of the 02K80F-40ML5 (1088 units versus 660 units) may provide supply chain advantages for high-volume procurement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 02K80F-40ML5 be used as a direct replacement for the 02K80A-40ML5 in existing designs?

A: Electrical substitution is complete; however, PCB layout modification is required. The 45° mounting angle of the 02K80F-40ML5 differs from the 90° right angle configuration of the 02K80A-40ML5. Verify that your PCB footprint and mechanical clearances accommodate the alternative mounting geometry before implementation.

Q: Are there any performance differences between these two connectors?

A: No. Both connectors maintain identical electrical performance across all specified parameters: 50 ohm impedance, 40 GHz maximum frequency, 250 V voltage rating, and 500 mating cycle durability. Performance differences are mechanical only, relating to connector orientation.

Q: What is the significance of the mounting angle difference?

A: The mounting angle determines the physical orientation of the connector relative to the PCB surface. Right angle (90°) connectors extend perpendicular to the board, while 45° connectors provide intermediate angular positioning. Selection depends on available space, cable routing requirements, and mechanical stress considerations in your specific application.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 02K80A-40ML5 and 02K80F-40ML5 are ROHS3 compliant and REACH affected, meeting current environmental and hazardous substance regulations for electronic component manufacturing and distribution.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard warehouse conditions without requiring desiccant packaging or controlled humidity environments.

Q: How do the inventory levels compare?

A: The 02K80F-40ML5 has 1088 units in stock compared to 660 units for the 02K80A-40ML5. For high-volume orders or time-sensitive procurement, the 02K80F-40ML5 may offer better availability.
