Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASMT-AA00-ARS01 is based on the following critical parameters:

Color Match: Both parts must emit amber wavelength light. The ASMT-AA00-ARS01 operates at 590nm typical; acceptable substitutes must maintain amber color output within the amber spectrum range.

Electrical Compatibility: Forward voltage (Vf) and test current must align to ensure proper circuit operation. The ASMT-AA00-ARS01 specifies 2.1V typical at 350mA test current with a maximum current rating of 500mA.

Luminous Output: Luminous flux and efficiency (lm/W) determine brightness performance. The original part delivers 50lm typical at 25°C with 68 lm/W efficiency.

Mounting and Package: Surface mount technology is required. The original uses a 2-SMD, Gull Wing Exposed Pad configuration; substitutes must be compatible with surface mount assembly processes.

Compliance and Regulatory Status: RoHS3 compliance and REACH unaffected status are mandatory for equivalent parts in regulated markets.

The ASMT-JA10-ARS01 qualifies as a substitute based on matching color (amber), electrical parameters (2.1V Vf, 350mA test current, 500mA max), surface mount technology, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The ASMT-JA10-ARS01 is the manufacturer-recommended substitute for the obsolete ASMT-AA00-ARS01. Both parts are manufactured by Broadcom Limited and maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across markets.

The substitute part offers improved performance characteristics: higher luminous flux (54lm typical versus 50lm), superior efficiency (73 lm/W versus 68 lm/W), and a wider viewing angle (165° versus 140°). Electrical parameters remain identical (2.1V Vf, 350mA test current, 500mA maximum current), ensuring direct circuit compatibility.

The ASMT-JA10-ARS01 features a smaller footprint (4.00mm x 4.00mm versus 8.00mm diameter) and lower profile (1.95mm versus 4.20mm), enabling more compact PCB layouts. The 6-SMD Flat Lead Exposed Pad package differs from the original 2-SMD Gull Wing configuration, requiring PCB layout and assembly process adjustments.

The substitute part carries MSL 1 (Unlimited) moisture sensitivity versus MSL 2A (4 Weeks) for the original, reducing handling and storage constraints during manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the ASMT-JA10-ARS01 directly replace the ASMT-AA00-ARS01 without circuit modifications?

A: Electrical parameters are identical (2.1V Vf, 350mA test current, 500mA maximum current), allowing direct circuit replacement. However, the package footprint differs (6-SMD Flat Lead versus 2-SMD Gull Wing), requiring PCB layout redesign and assembly process updates.

Q: What is the wavelength difference between these parts?

A: The original operates at 590nm typical; the substitute operates at 592nm typical (587nm to 597nm range). Both emit amber color within the amber spectrum and are visually indistinguishable in typical applications.

Q: Does the substitute part provide better performance?

A: The ASMT-JA10-ARS01 delivers higher luminous flux (54lm versus 50lm), improved efficiency (73 lm/W versus 68 lm/W), and a wider viewing angle (165° versus 140°). Thermal resistance is also improved (9°C/W versus 10°C/W).

Q: Are there package compatibility concerns?

A: Yes. The original uses a 2-SMD Gull Wing Exposed Pad package (8.00mm diameter, 4.20mm height); the substitute uses a 6-SMD Flat Lead Exposed Pad package (4.00mm x 4.00mm, 1.95mm height). PCB footprints and assembly processes must be updated accordingly.

Q: What are the moisture sensitivity differences?

A: The original part is MSL 2A (4 weeks shelf life at controlled humidity); the substitute is MSL 1 (unlimited shelf life). The substitute offers superior moisture tolerance and reduced handling constraints.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ASMT-AA00-ARS01 and ASMT-JA10-ARS01 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.
