Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SML-010LTT87 is determined by the following critical parameters: package type (1208/3020 Metric), mounting method (surface mount), color (red), lens transparency (clear), forward voltage (1.75V ±tolerance), test current (20mA), and physical dimensions (3.00mm L x 2.00mm W x 1.50mm H max). Parts are grouped into three categories based on substitution relationship type:

Direct Manufacturer Equivalents maintain identical electrical and mechanical specifications from the same or different manufacturer, ensuring pin-for-pin and form-factor compatibility.

Parametric Equivalents share the same base electrical characteristics (voltage, current, wavelength range, brightness class) and package footprint but may originate from different product lines or have minor specification variations that do not affect circuit-level performance.

Similar Substitutes operate within the same functional category and package but may have different brightness ratings or wavelength specifications, requiring circuit-level evaluation for brightness-critical applications.

Parameter Comparison

Engineering Selection Recommendations

S7L-010LTT87L is the preferred direct manufacturer equivalent from Rohm Semiconductor with Active product status. This part maintains compatibility with existing designs while providing ongoing manufacturer support and supply continuity.

SML-010LTT86 is a parametric equivalent from Rohm Semiconductor with identical electrical specifications (1.75V, 16mcd, 660nm) and mechanical form factor. Both parts share Not For New Designs status, making this substitution suitable for legacy production support only.

5973111502F from Dialight is a direct cross-reference with Active product status, matching all critical electrical parameters (1.75V, 16mcd, 660nm peak wavelength) and mechanical dimensions. This part provides an alternative manufacturer source with improved supply availability and current production status.

SML-012V8TT86 is a similar substitute with higher brightness (63mcd) and elevated forward voltage (2.2V). This part is suitable only for applications where increased brightness is acceptable and circuit design accommodates the higher voltage drop. The improved MSL rating (2 vs 3) provides better moisture handling characteristics.

For new designs, S7L-010LTT87L or 5973111502F are recommended due to Active product status. For legacy production support, SML-010LTT86 maintains full compatibility. SML-012V8TT86 requires circuit-level evaluation due to brightness and voltage differences.

Frequently Asked Questions (FAQ)

Q: Can SML-010LTT86 be used as a direct replacement for SML-010LTT87?

A: Yes. Both parts share identical electrical specifications (1.75V forward voltage, 16mcd brightness, 660nm peak wavelength), mechanical dimensions (3.00mm x 2.00mm x 1.50mm), and package type (1208/3020 Metric). The primary difference is packaging format (Tape & Reel for both), making this a parametric equivalent suitable for direct substitution.

Q: What is the key difference between SML-010LTT87 and SML-012V8TT86?

A: SML-012V8TT86 operates at 2.2V forward voltage (versus 1.75V) and provides 63mcd brightness (versus 16mcd). These differences require circuit-level evaluation. The higher voltage drop affects current-limiting resistor calculations, and the increased brightness may be unsuitable for applications requiring lower light output. Both maintain the same 1208 package footprint.

Q: Is 5973111502F from Dialight compatible with the SML-010LTT87 footprint?

A: Yes. The 5973111502F maintains identical mechanical dimensions (3.00mm L x 2.00mm W x 1.50mm H) and 1208 (3020 Metric) package specification. Electrical parameters match exactly (1.75V, 16mcd, 660nm peak wavelength, 20mA test current), enabling direct footprint and circuit compatibility.

Q: Why is S7L-010LTT87L recommended over SML-010LTT87 for new designs?

A: S7L-010LTT87L carries Active product status from Rohm Semiconductor, ensuring ongoing manufacturer support, supply continuity, and compliance with current industry standards. SML-010LTT87 is classified as Not For New Designs, indicating end-of-life status and potential supply constraints.

Q: Can SML-012V8TT86 be used in brightness-critical applications?

A: SML-012V8TT86 provides 63mcd brightness compared to 16mcd for the SML-010LTT87, representing a 4x increase. This substitution is suitable only for applications where higher brightness is acceptable or required. Circuit design must account for the 2.2V forward voltage versus 1.75V, affecting resistor selection and power dissipation calculations.

Q: What is the moisture sensitivity difference between these parts?

A: SML-010LTT87, SML-010LTT86, and 5973111502F all carry MSL 3 (168 Hours) rating. SML-012V8TT86 carries MSL 2 (1 Year), providing superior moisture resistance and extended shelf life. MSL 2 parts require less stringent moisture control during storage and handling compared to MSL 3 parts.
