Key Parameters

Substitute Part Grouping Explanation

Substitution of the SML010BATT86 is determined by the following critical parameters:

• Color and Wavelength: Blue LED indication function requires matching color classification (blue) and wavelength range compatibility (466nm dominant wavelength)
• Mounting Type: Surface mount requirement must be maintained
• Electrical Characteristics: Forward voltage (Vf) and test current must be compatible with existing circuit design
• Package Compatibility: Physical dimensions and case style affect PCB layout and assembly processes
• Compliance Status: RoHS3 compliance and REACH status must be maintained for regulatory requirements

The substitute part SMLZN4BGTT86A from Rohm Semiconductor meets the functional requirements for blue LED indication while maintaining surface mount compatibility and regulatory compliance. This substitute operates at a lower forward voltage (3.3V vs 3.8V) and delivers significantly higher luminous intensity (300mcd vs 9mcd), making it suitable for applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The SMLZN4BGTT86A is an active product from Rohm Semiconductor with confirmed inventory availability (15,400 pcs), providing long-term supply security compared to the obsolete SML010BATT86. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Selection of SMLZN4BGTT86A requires consideration of the following differences:

• Forward Voltage: The substitute operates at 3.3V versus 3.8V, reducing power dissipation by approximately 13% at 20mA test current
• Luminous Intensity: The substitute delivers 300mcd versus 9mcd, providing 33x greater brightness
• Package Dimensions: The substitute uses a 3528 package (3.20mm L x 2.80mm W x 2.05mm H) versus the original 3020 package (3.00mm L x 2.00mm W x 1.50mm H), requiring PCB layout verification
• Lens Geometry: The substitute features a round flat-top lens versus the original rectangular flat-top lens

Frequently Asked Questions (FAQ)

Q: Can SMLZN4BGTT86A be used as a direct replacement for SML010BATT86?

A: SMLZN4BGTT86A provides functional equivalence for blue LED indication applications. However, the different package dimensions (3528 vs 3020) and lens geometry (round vs rectangular) require PCB layout verification before implementation. The higher luminous intensity (300mcd vs 9mcd) and lower forward voltage (3.3V vs 3.8V) must be evaluated against circuit design requirements.

Q: What are the key compatibility factors for this substitution?

A: The primary compatibility factors are color (blue), wavelength range (466nm to 470nm), mounting type (surface mount), test current (20mA), lens transparency (clear), and regulatory compliance (ROHS3, REACH unaffected). Package dimensions and lens style are secondary factors requiring design review.

Q: Does the lower forward voltage of SMLZN4BGTT86A affect circuit design?

A: The 0.5V reduction in forward voltage (3.8V to 3.3V) affects current-limiting resistor calculations and power dissipation. Circuit designs using fixed resistor values must be re-evaluated to ensure proper current limiting and brightness control.

Q: Are there any moisture sensitivity considerations?

A: Both components carry MSL 3 (168 Hours) classification, indicating identical moisture sensitivity requirements. Standard moisture control procedures during storage, handling, and assembly apply equally to both parts.

Q: What is the impact of the package size difference?

A: The SMLZN4BGTT86A 3528 package is larger than the original 3020 package. PCB layout modifications may be required to accommodate the increased footprint. Component placement and spacing must be verified against design constraints.
