Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AA3022SRC-4.5SF is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color: Red
• Mounting Type: Surface Mount
• Lens Transparency: Clear
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Allowable Parameter Variations:

• Voltage - Forward (Vf): Tolerance range 1.85V to 2.2V (within typical LED forward voltage variation for red indication LEDs)
• Millicandela Rating: 100mcd to 150mcd (brightness variation acceptable for indication applications)
• Wavelength - Dominant: 620nm to 640nm (red spectrum range for visual indication)
• Viewing Angle: 90° to 110° (acceptable variation for indication circuits)
• Package / Case: 2-SMD Gull Wing or 1208 (3020 Metric) equivalent footprints
• Size / Dimension: Variations within 3.00mm L x 2.00mm W to 3.00mm L x 2.20mm W
• Height (Max): 1.30mm to 1.65mm (PCB clearance dependent on application)

The substitute part 5973032507F from Dialight meets all mandatory criteria and operates within allowable parameter variations for functional equivalence in red LED indication circuits.

Engineering Selection Recommendations

Primary Part Selection (AA3022SRC-4.5SF): Select the primary part when inventory availability permits and forward voltage specification of 1.85V is required for circuit design. This part maintains active product status and ROHS3 compliance with established supply chain availability of 1023 units in stock.

Substitute Part Selection (5973032507F): The Dialight 5973032507F serves as a functional equivalent when the primary part is unavailable or lead times exceed project requirements. This substitute maintains ROHS3 compliance and active product status. The forward voltage increase to 2.2V requires circuit verification to confirm compatibility with existing current-limiting resistor values. The reduced millicandela rating (100mcd versus 150mcd) is acceptable for indication applications where brightness variation does not impact functional requirements. The 1208 package footprint is mechanically compatible with standard 2-SMD Gull Wing PCB layouts. Higher viewing angle (110° versus 90°) provides expanded visibility without functional degradation.

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.41.0000.

Frequently Asked Questions (FAQ)

Q: Can the 5973032507F directly replace the AA3022SRC-4.5SF without circuit modification?

A: The 5973032507F is mechanically and functionally compatible for most indication applications. However, the forward voltage difference (2.2V versus 1.85V) requires verification of the current-limiting resistor value in the circuit. If the resistor was calculated specifically for 1.85V operation, recalculation is necessary to maintain 20mA test current with the 2.2V substitute part.

Q: What is the impact of the 50mcd brightness difference between these parts?

A: The AA3022SRC-4.5SF provides 150mcd while the 5973032507F provides 100mcd. For red LED indication circuits, this 33% reduction in luminous intensity is typically acceptable. Visual perception of indicator status remains clear in standard indoor lighting conditions. Applications requiring maximum brightness should retain the primary part.

Q: Are the package dimensions compatible for PCB layout?

A: Both parts use surface mount technology with compatible footprints. The AA3022SRC-4.5SF measures 3.00mm L x 2.20mm W with 1.65mm maximum height. The 5973032507F measures 3.00mm L x 2.00mm W with 1.30mm maximum height. The substitute part is slightly smaller and lower profile, providing additional PCB clearance without requiring layout redesign.

Q: Does the wavelength difference affect visual appearance?

A: The AA3022SRC-4.5SF operates at 640nm dominant wavelength while the 5973032507F operates at 620nm. Both wavelengths fall within the red spectrum visible to human perception. The 620nm wavelength may appear slightly more orange-red compared to the 640nm part, but this difference is not significant for indication applications.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The AA3022SRC-4.5SF has MSL 4 (72 hours) while the 5973032507F has MSL 3 (168 hours). Both parts require standard moisture control during storage and handling. The substitute part allows extended storage time before reflow soldering, providing additional process flexibility.

Q: Can these parts be used interchangeably in existing inventory?

A: These parts are substitutes for specific applications where the primary part is unavailable. They should not be mixed in the same inventory bin without clear labeling and circuit-specific documentation, as the forward voltage difference requires different resistor calculations.
