Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMP2-SBWC are grouped based on strict adherence to the following critical parameters:

Primary Substitution Criteria:

• Color: Blue
• Package / Case: 2-PLCC
• Mounting Type: Surface Mount
• Size / Dimension: 3.20mm L x 2.80mm W
• Voltage - Forward (Vf) (Typ): 3.2V to 3.4V (acceptable tolerance range)
• Current - Test: 20mA
• Viewing Angle: 120°
• Lens Color: Colorless
• Lens Transparency: Clear
• Lens Style: Round with Flat Top

Parametric Equivalent: SMTL2-SBWC matches all primary criteria with identical electrical and mechanical specifications. This part is the direct equivalent with active product status.

Similar Substitutes: Parts 67-21/B7C-AS2U1N/2T, AA3528VRBXS/A-SC-AMT, and SMLZN4BGTT86A maintain compatibility across package, mounting, color, lens, and viewing angle parameters. These parts operate within acceptable voltage ranges (3.2V to 3.3V) and current specifications. Brightness ratings vary (187.5mcd to 1300mcd) and wavelength dominants range from 468nm to 471nm, remaining within blue spectrum parameters.

Limited Compatibility: HSMN-A161-N00J1 and 67-11/BHC-FQ2S1F/2T present reduced compatibility. HSMN-A161-N00J1 operates at 3.4V (outside typical tolerance) and provides only 50mcd brightness. 67-11/BHC-FQ2S1F/2T uses 1411 (3528 Metric) package with 0.80mm height, differing from the 2-PLCC standard package footprint.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SMTL2-SBWC

SMTL2-SBWC is the parametric equivalent to SMP2-SBWC. This part maintains identical electrical specifications (3.2V, 20mA, 285mcd, 470nm) and mechanical dimensions (3.20mm L x 2.80mm W, 2-PLCC package). SMTL2-SBWC holds active product status with ROHS3 compliance and identical MSL rating. Packaging is available in Tape & Reel (TR) format with 1322 units in stock. This part provides direct substitution without design modification.

Secondary Recommendations: 67-21/B7C-AS2U1N/2T, AA3528VRBXS/A-SC-AMT, SMLZN4BGTT86A

These three parts maintain full mechanical and package compatibility with identical 2-PLCC footprints and 3.20mm L x 2.80mm W dimensions. All three are active products with ROHS3 compliance.

67-21/B7C-AS2U1N/2T (Everlight) operates at 3.2V with 395mcd brightness and 471nm wavelength. MSL rating is 3 (168 Hours), providing improved moisture handling compared to the main part.

AA3528VRBXS/A-SC-AMT (Kingbright) operates at 3.3V with significantly higher brightness (1300mcd) and 120° viewing angle. This part is suitable for applications requiring increased luminous intensity. MSL rating is 3 (168 Hours). Inventory availability is highest at 28,108 units.

SMLZN4BGTT86A (Rohm Semiconductor) operates at 3.3V with 300mcd brightness and 470nm wavelength. This part belongs to the SML-Z1/ZN series with active product status and ROHS3 compliance. MSL rating is 3 (168 Hours). Inventory is 15,400 units.

Limited Compatibility: HSMN-A161-N00J1, 67-11/BHC-FQ2S1F/2T

HSMN-A161-N00J1 (Broadcom) is obsolete with 3.4V forward voltage and only 50mcd brightness, representing significant electrical and optical deviation. This part is not recommended for new designs.

67-11/BHC-FQ2S1F/2T (Everlight) uses 1411 (3528 Metric) package with 0.80mm height, differing from standard 2-PLCC footprint. This package incompatibility requires PCB redesign and is not recommended as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can SMTL2-SBWC directly replace SMP2-SBWC without PCB modification?

A: Yes. SMTL2-SBWC is the parametric equivalent with identical electrical specifications (3.2V, 20mA, 285mcd), mechanical dimensions (3.20mm L x 2.80mm W), and 2-PLCC package footprint. No PCB redesign is required.

Q: What is the difference between the main part SMP2-SBWC and SMTL2-SBWC?

A: The primary difference is product status and packaging format. SMP2-SBWC is obsolete with unspecified packaging, while SMTL2-SBWC is active with Tape & Reel (TR) packaging. Electrical and mechanical specifications are identical.

Q: Can AA3528VRBXS/A-SC-AMT be used as a direct substitute?

A: AA3528VRBXS/A-SC-AMT maintains full package and mechanical compatibility (2-PLCC, 3.20mm L x 2.80mm W). However, it operates at 3.3V (0.1V higher) and provides 1300mcd brightness (4.6x higher than the main part). Circuit design must accommodate the higher forward voltage and brightness. This part is suitable for applications where increased luminous intensity is acceptable or beneficial.

Q: What are the key parameters that determine substitution compatibility?

A: Critical parameters are color (Blue), package type (2-PLCC), mounting type (Surface Mount), physical dimensions (3.20mm L x 2.80mm W), forward voltage (3.2V to 3.4V range), test current (20mA), viewing angle (120°), lens color (Colorless), lens transparency (Clear), and lens style (Round with Flat Top). Deviations in these parameters require design review.

Q: Why is 67-11/BHC-FQ2S1F/2T not recommended as a substitute?

A: 67-11/BHC-FQ2S1F/2T uses 1411 (3528 Metric) package with 0.80mm height, compared to the standard 2-PLCC package. This package incompatibility requires PCB footprint redesign. Additionally, brightness is 187.5mcd (34% lower than the main part). This part is not suitable for direct substitution.

Q: What is the impact of MSL rating differences?

A: The main part SMP2-SBWC has MSL 4 (72 Hours), while most active substitutes have MSL 3 (168 Hours). Lower MSL numbers indicate better moisture resistance and longer shelf life. Substitutes with MSL 3 provide improved handling and storage characteristics. HSMN-A161-N00J1 has MSL 2A (4 Weeks), offering superior moisture protection but is obsolete.

Q: Are all substitute parts ROHS3 compliant?

A: SMTL2-SBWC, 67-21/B7C-AS2U1N/2T, AA3528VRBXS/A-SC-AMT, SMLZN4BGTT86A, and HSMN-A161-N00J1 are ROHS3 compliant. 67-11/BHC-FQ2S1F/2T does not specify RoHS status in the provided data.

Q: Which substitute has the best inventory availability?

A: AA3528VRBXS/A-SC-AMT has the highest inventory at 28,108 units. SMLZN4BGTT86A has 15,400 units. SMTL2-SBWC has 1,322 units. All three are active products with reliable supply.

Q: Can wavelength differences affect circuit performance?

A: Wavelength differences (468nm to 471nm) represent minor variations within the blue spectrum and do not affect circuit electrical performance. These variations may produce slight visual color differences imperceptible in most applications. Optical design should account for brightness differences (50mcd to 1300mcd range) rather than wavelength variations.
