Category 2: Package Variant (Different Form Factor) Part with modified package geometry but compatible electrical performance: SML-LX2835IYC-TR (4-SMD J-Lead variant with reduced height)

Parameter Comparison

Engineering Selection Recommendations

For Direct 4-PLCC Package Replacement (Recommended Primary Path):

Select from active product status alternatives maintaining identical 4-PLCC package footprint and 2.10mm maximum height:

• HSMF-A212-A00J1 (Broadcom Limited): Provides highest red brightness (25mcd) matching yellow brightness profile, with 1.9V red forward voltage enabling lower power consumption. Active product status with ROHS3 compliance. Suitable for applications prioritizing red LED intensity.

• HSMF-A202-A00J1 (Broadcom Limited): Delivers balanced brightness (16mcd red, 12mcd yellow) with 2.2V forward voltage across both colors. Active product status with ROHS3 compliance. Suitable for applications requiring consistent voltage characteristics.

• 5977731207F (Dialight microLED® series): Provides active product status with superior moisture sensitivity rating (MSL 2, 1 Year versus MSL 3, 168 Hours). Tape & Reel packaging. Lower brightness (7.3mcd red, 6.8mcd yellow) and reduced test current (10mA) suitable for low-power applications. ROHS3 compliant.

• 5977731202F (Dialight microLED® series): Identical electrical and optical characteristics to 5977731207F with Strip packaging alternative. Active product status, ROHS3 compliant.

For Package Variant Replacement (Space-Constrained Applications):

• SML-LX2835IYC-TR (Lumex Opto/Components Inc.): Maintains Lumex manufacturer continuity with 4-SMD J-Lead package variant. Reduced height (1.80mm versus 2.10mm) for applications with vertical space constraints. Identical electrical characteristics (2V red, 2.1V yellow) and brightness ratings (15mcd red, 25mcd yellow) to original part. Active product status, ROHS3 compliant.

Compliance Verification: All substitute parts maintain ROHS3 compliance and EAR99 export classification matching the original SML-LX2832IYC-TR specifications.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace SML-LX2832IYC-TR with SML-LX2835IYC-TR without PCB modification?

A: The SML-LX2835IYC-TR uses a different package type (4-SMD J-Lead versus 4-PLCC). While both are surface mount components with identical electrical characteristics, the footprint differs. PCB layout modification is required. The 2835 variant offers reduced height (1.80mm versus 2.10mm), which may be advantageous for space-constrained designs.

Q2: What are the key electrical differences between Dialight 5977731207F and Broadcom HSMF-A212-A00J1?

A: Both parts maintain 4-PLCC package compatibility and 120° viewing angle. Primary differences: Dialight 5977731207F operates at 10mA test current with 7.3mcd red and 6.8mcd yellow brightness; Broadcom HSMF-A212-A00J1 operates at 20mA test current with 25mcd red and 12mcd yellow brightness. Forward voltage differs: Dialight at 2.0V both colors; Broadcom at 1.9V red and 2.2V yellow. Select based on brightness requirements and available drive current.

Q3: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (SML-LX2835IYC-TR, 5977731202F, 5977731207F, HSMF-A202-A00J1, HSMF-A212-A00J1) maintain ROHS3 compliance matching the original SML-LX2832IYC-TR specification.

Q4: Which substitute part has the best moisture sensitivity rating?

A: Dialight parts (5977731202F and 5977731207F) provide MSL 2 rating (1 Year storage), superior to the original part's MSL 3 rating (168 Hours). Broadcom parts provide MSL 2A rating (4 Weeks). For applications requiring extended storage or humid environment exposure, Dialight microLED® series offers superior moisture protection.

Q5: Can I use lower brightness Dialight parts in existing designs?

A: Dialight 5977731202F and 5977731207F deliver 7.3mcd red and 6.8mcd yellow brightness, approximately 50% lower than the original SML-LX2832IYC-TR (15mcd red, 25mcd yellow). Substitution is valid only if application design accommodates reduced brightness. Verify visibility requirements under intended operating conditions before selection.

Q6: What is the primary advantage of HSMF-A212-A00J1 over other substitutes?

A: HSMF-A212-A00J1 delivers the highest red brightness (25mcd) among all substitutes, matching the original yellow brightness level. This provides balanced brightness perception across both color channels. Additionally, the 1.9V red forward voltage enables lower power consumption compared to alternatives operating at 2.0V to 2.2V.

Q7: Are there packaging format differences affecting assembly?

A: Yes. The original SML-LX2832IYC-TR and all 4-PLCC substitutes (5977731202F, 5977731207F, HSMF-A202-A00J1, HSMF-A212-A00J1) use identical 4-PLCC package with 3.20mm L x 2.80mm W footprint and 2.10mm height. The SML-LX2835IYC-TR variant uses 4-SMD J-Lead package with 3.20mm L x 2.70mm W footprint and 1.80mm height, requiring PCB redesign. Dialight parts are available in Tape & Reel (5977731207F) or Strip (5977731202F) packaging formats.
