Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for yellow LED indication components is determined by strict alignment of electrical and mechanical parameters. The following criteria establish functional equivalence:

Electrical Parameters (Critical):

• Forward voltage (Vf) must match at 2.1V to ensure compatibility with existing current-limiting circuit designs
• Test current specification of 20mA establishes the operating point
• Color specification must remain yellow for indication function

Optical Parameters (Critical):

• Viewing angle of 90° maintains consistent optical distribution
• Lens size of 2.00mm x 1.40mm ensures physical compatibility with PCB layout and mechanical constraints
• Lens transparency (Clear) and lens color (Colorless) maintain optical performance

Mechanical Parameters (Critical):

• Package type 2-SMD, J-Lead defines footprint compatibility
• Surface mount mounting type ensures assembly process compatibility
• Physical dimensions must accommodate existing PCB design constraints

Compliance Parameters:

• ROHS3 compliance status required for regulatory alignment
• Active product status ensures ongoing availability and support

The substitute part SML-LX23YC-TR meets all critical electrical and mechanical parameters while maintaining regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Substitution Validity:

The SML-LX23YC-TR qualifies as a functional equivalent to the AA3020AYC based on matching critical electrical parameters (2.1V forward voltage, 20mA test current), identical optical specifications (90° viewing angle, 2.00 x 1.40mm lens size, clear colorless lens), and compatible package format (2-SMD J-Lead surface mount). Both components maintain ROHS3 compliance and active product status.

Dimensional Considerations:

The substitute part exhibits a length dimension of 3.00mm compared to the main part's 2.70mm, representing a 0.30mm increase. The substitute part height is 1.40mm versus the main part's 1.65mm maximum, representing a 0.25mm reduction. These dimensional variations require verification against specific PCB layout constraints and mechanical clearance requirements in the target application.

Performance Characteristics:

The SML-LX23YC-TR delivers 20mcd luminous intensity compared to the AA3020AYC's 15mcd, representing a 33% increase in brightness at the specified 20mA test current. This higher intensity output remains within the yellow LED indication category and does not compromise circuit compatibility.

Moisture and Environmental Handling:

The substitute part carries MSL rating of 3 (168 hours) compared to the main part's MSL rating of 4 (72 hours), indicating superior moisture resistance and extended shelf life under controlled storage conditions.

Packaging Format:

The main part is supplied in standard packaging format, while the substitute part is supplied in Tape & Reel (TR) format. This difference affects procurement quantity minimums and assembly line integration but does not impact electrical or optical performance.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX23YC-TR replace the AA3020AYC in existing circuit designs?

A: Yes. Both components operate at identical forward voltage (2.1V) and test current (20mA), ensuring compatibility with existing current-limiting resistor calculations and circuit topology. The substitute part's higher luminous intensity (20mcd versus 15mcd) does not create circuit incompatibility.

Q: What is the significance of the 0.30mm length difference between the two parts?

A: The substitute part measures 3.00mm in length compared to the main part's 2.70mm. This 0.30mm increase must be evaluated against PCB layout constraints, mechanical clearance requirements, and any space-limited applications. Verification against specific PCB design files is required before implementation.

Q: Does the lower height of the substitute part affect performance?

A: No. The substitute part's maximum height of 1.40mm compared to the main part's 1.65mm does not affect electrical or optical performance. The lower profile may provide advantages in space-constrained applications and does not compromise lens optical properties or viewing angle characteristics.

Q: Are there differences in wavelength between the two parts?

A: The main part specifies a peak wavelength of 590nm, while the substitute part specifies 585nm. Both values fall within the standard yellow LED wavelength range and produce visually equivalent yellow indication. The 5nm difference is not perceptible in typical indication applications.

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

A: The substitute part carries MSL 3 (168 hours) compared to the main part's MSL 4 (72 hours). This indicates the substitute part maintains performance under moisture exposure for extended periods. Both ratings are suitable for standard PCB assembly processes. Storage conditions must comply with the respective MSL specifications.

Q: Does the Tape & Reel packaging of the substitute part affect compatibility?

A: No. Tape & Reel (TR) packaging is a standard format for automated assembly processes and does not affect component electrical or optical performance. Packaging format differences impact procurement quantity minimums and assembly line integration but not functional equivalence.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the AA3020AYC and SML-LX23YC-TR maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Both components meet current regulatory requirements for electronic component use.

Q: Can the substitute part be used in high-volume production?

A: Yes. The SML-LX23YC-TR is supplied in Tape & Reel format with 2973 pieces in stock, supporting high-volume automated assembly processes. The active product status of both components ensures ongoing availability for production requirements.
