Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SML012BCTT86 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Color: Blue
• Lens Transparency: Clear
• Voltage - Forward (Vf): 3.2V to 3.3V
• Current - Test: 20mA
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Secondary Considerations:

• Package compatibility (1208 preferred; 2-PLCC acceptable with mechanical redesign)
• Millicandela rating within acceptable range for indication applications
• Wavelength in blue spectrum (468nm to 470nm)

Substitute parts are categorized as follows:

Direct Substitutes (Same Package - 1208):

• SML013BNTT86 (Rohm Semiconductor)
• 5973602507F (Dialight)

Compatible Substitute (Different Package - 2-PLCC):

• SMLZ14BGTT86 (Rohm Semiconductor)

Parameter Comparison

Engineering Selection Recommendations

For Direct Package Replacement (1208 Package):

SML013BNTT86 is the preferred substitute. This part maintains identical package dimensions and mounting footprint, enabling direct PCB compatibility without layout modifications. Forward voltage is 3.2V, within acceptable tolerance of the original 3.3V specification. The higher millicandela rating (250mcd vs. 100mcd) provides increased luminous intensity for the same current draw. Product status is active, ensuring long-term availability and supply chain stability.

5973602507F from Dialight provides an alternative direct package replacement with matching 3.3V forward voltage and 100mcd rating. This part is active and maintains identical package dimensions. Height is reduced to 1.30mm maximum, which may be advantageous in space-constrained applications.

For Applications Allowing Package Redesign:

SMLZ14BGTT86 is a compatible substitute when PCB layout modifications are acceptable. This part uses the 2-PLCC package with increased millicandela rating (280mcd) and maintains 3.3V forward voltage. The larger footprint (3.20mm L x 2.80mm W) and increased height (2.05mm) require mechanical redesign. Product status is obsolete; however, inventory availability is documented.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original component. Moisture sensitivity levels vary; SML013BNTT86 specifies MSL 3 (168 Hours), while SMLZ14BGTT86 specifies MSL 4 (72 Hours), requiring appropriate handling protocols during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can SML013BNTT86 be used as a direct replacement for SML012BCTT86?

A: Yes. Both parts use the 1208 (3020 Metric) package with identical footprint dimensions (3.00mm L x 2.00mm W, 1.50mm height). Forward voltage differs by 0.1V (3.2V vs. 3.3V), which is within acceptable tolerance for LED indication circuits. The higher luminous intensity (250mcd vs. 100mcd) is compatible with applications designed for the original part.

Q: What is the difference between the 1208 and 2-PLCC packages?

A: The 1208 package is a rectangular surface mount component measuring 3.00mm x 2.00mm with 1.50mm maximum height. The 2-PLCC package is a larger rectangular component measuring 3.20mm x 2.80mm with 2.05mm maximum height. Direct PCB footprint compatibility exists only between parts using the same package designation. SMLZ14BGTT86 (2-PLCC) requires PCB layout redesign if replacing a 1208 package part.

Q: Are there any electrical differences between the substitute parts?

A: Forward voltage ranges from 3.2V to 3.3V across all substitutes, which is acceptable for standard LED indication circuits. Millicandela ratings vary from 100mcd to 280mcd; higher ratings provide increased brightness at identical current levels. Wavelength specifications are consistent in the blue spectrum (468nm to 470nm). All parts operate at 20mA test current.

Q: Which substitute offers the best long-term availability?

A: SML013BNTT86 and 5973602507F both carry active product status, indicating ongoing manufacturer support and supply chain availability. SMLZ14BGTT86 is classified as obsolete, similar to the original SML012BCTT86, and should be considered only when inventory is confirmed available.

Q: What are the moisture sensitivity requirements for these parts?

A: SML012BCTT86 specifies MSL 2 (1 Year). SML013BNTT86 specifies MSL 3 (168 Hours), and 5973602507F specifies MSL 3 (168 Hours). SMLZ14BGTT86 specifies MSL 4 (72 Hours). Higher MSL levels require more stringent moisture control during storage and assembly. Appropriate baking procedures must be followed if parts exceed their moisture exposure limits.
