ASMT-YTB0-0AA02 Equivalent & Substitute Parts

Part Overview

The ASMT-YTB0-0AA02 is an RGB LED indicator in 6-SMD, J-Lead surface mount package manufactured by Broadcom Limited. This part features independent red, green, and blue emitters with a clear, colorless lens and rectangular flat-top design. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support and production continuity. The ASMT-YTB7-0AA02 serves as the manufacturer-recommended substitute, offering active product status with compatible electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

The ASMT-YTB7-0AA02 qualifies as a direct substitute based on the following criteria:

Electrical Compatibility: Forward voltages are within acceptable tolerance (Red: 2.1V identical; Green: 3.1V vs 3.2V; Blue: 3.1V vs 3.2V). Test current remains constant at 20mA across all emitters. Wavelength specifications remain within the visible spectrum ranges for each color channel.

Mechanical Compatibility: Both parts use identical 6-SMD, J-Lead package configuration (6-PLCC supplier package). Surface mount mounting type is preserved. Pin configuration and footprint remain compatible.

Configuration: Independent RGB configuration is maintained, allowing identical circuit integration and control logic.

Key Differentiators: The substitute features a diffused lens versus clear lens, smaller physical footprint (3.00mm x 2.80mm vs 4.40mm x 4.00mm), reduced height (2.00mm vs 3.70mm), and improved viewing angle (120° vs 115°). Product status transitions from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The ASMT-YTB7-0AA02 is the manufacturer-recommended substitute for the obsolete ASMT-YTB0-0AA02. Selection of the substitute is justified by:

Product Continuity: The main part is obsolete. The substitute maintains active product status with full manufacturer support and availability.

Electrical Equivalence: Forward voltage specifications are within standard operating tolerances. Red channel voltage is identical; green and blue channels differ by 0.1V, which is acceptable for LED indicator applications. Test current specifications are identical across all color channels.

Mechanical Compatibility: Both parts share identical 6-SMD, J-Lead package configuration and surface mount mounting type, ensuring PCB footprint compatibility without redesign.

Compliance: The substitute carries ROHS3 compliance certification, meeting current regulatory requirements. Both parts maintain REACH Unaffected status and identical ECCN/HTSUS classifications.

Physical Considerations: The substitute features a smaller footprint and lower profile, which may provide layout advantages in space-constrained designs. The diffused lens provides different optical characteristics compared to the clear lens of the main part; this should be evaluated against specific application requirements for light distribution and visibility.

Brightness Characteristics: The substitute provides higher millicandela ratings for green and blue channels, resulting in increased brightness. This may require circuit adjustment if the original design relied on specific brightness levels.

Frequently Asked Questions (FAQ)

Q: Can the ASMT-YTB7-0AA02 be used as a direct drop-in replacement for the ASMT-YTB0-0AA02?

A: Yes, from an electrical and mechanical standpoint. Both parts use identical 6-SMD, J-Lead packages and surface mount configuration. Forward voltages are within acceptable tolerance. However, the diffused lens of the substitute produces different light distribution compared to the clear lens of the original part. Evaluate optical requirements for your specific application.

Q: What are the key electrical differences between these parts?

A: Forward voltages for green and blue channels differ by 0.1V (3.2V vs 3.1V). Red channel voltage is identical at 2.1V. Test current remains constant at 20mA for all channels. These differences are within standard operating tolerances for LED indicator circuits.

Q: How do the optical characteristics differ?

A: The main part features a clear, colorless lens with a rectangular flat-top design and 115° viewing angle. The substitute features a diffused lens with a square flat-top design and 120° viewing angle. The diffused lens provides wider light distribution; the clear lens provides more directional light output. The substitute also offers higher brightness ratings for green and blue channels.

Q: Are there physical size differences that affect PCB layout?

A: Yes. The substitute is significantly smaller: 3.00mm x 2.80mm versus 4.40mm x 4.00mm, with reduced height (2.00mm vs 3.70mm). The footprint is compatible with the same 6-PLCC package, but the smaller physical dimensions may allow for tighter component spacing in new designs.

Q: What is the difference in moisture sensitivity levels?

A: The main part has MSL 2A (4 weeks); the substitute has MSL 3 (168 hours). MSL 3 allows longer shelf life at standard humidity conditions. Both ratings are suitable for standard manufacturing processes.

Q: Does the substitute meet current compliance requirements?

A: Yes. The substitute carries ROHS3 compliance certification, meeting current regulatory standards. Both parts maintain REACH Unaffected status and identical ECCN/HTSUS classifications for export control purposes.

Q: Why is the substitute recommended by the manufacturer?

A: The main part is obsolete with no ongoing production. The substitute is an active product with full manufacturer support, ensuring long-term availability and supply chain continuity. Broadcom Limited has qualified the ASMT-YTB7-0AA02 as the direct replacement based on electrical and mechanical compatibility.
