SML-010LTT86 Equivalent & Substitute Parts

Part Overview

The SML-010LTT86 is a red LED indication component manufactured by Rohm Semiconductor in 1208 (3020 Metric) surface mount package. This part is classified as Not For New Designs, indicating it has reached end-of-life status. The component delivers 16mcd brightness at 1.75V forward voltage with 660nm peak wavelength, designed for discrete LED indication applications in compact form factors.

Due to its discontinued design status, equivalent and substitute parts are necessary for ongoing production support, legacy system maintenance, and design transitions to active product lines.

Substitute Part Grouping Explanation

Substitute parts for the SML-010LTT86 are classified into three categories based on electrical and mechanical compatibility:

Direct Equivalents maintain identical or near-identical electrical characteristics and physical form factors. These parts share the same package type (1208/3020 Metric), forward voltage (1.75V), brightness (16mcd), and wavelength (660nm peak). Direct equivalents include S7L-010LTT86L and 5973111502F.

Parametric Equivalents match the core electrical specifications (1.75V forward voltage, 16mcd brightness, 660nm wavelength) and package footprint but may differ in secondary characteristics such as product status or moisture sensitivity rating. SML-010LTT87 falls into this category.

Similar Substitutes share the same package type and mounting method but differ in one or more key electrical parameters. These parts maintain mechanical compatibility while offering alternative electrical performance. SML-012V8TT86 and XZMDK56W are classified as similar substitutes due to variations in forward voltage, brightness, or wavelength.

Substitution eligibility is determined by:

• Package / Case compatibility (1208/3020 Metric or equivalent)
• Mounting Type (Surface Mount)
• Color (Red)
• Forward Voltage tolerance for circuit design
• Brightness (mcd) requirements for application
• Wavelength specifications for optical requirements

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

S7L-010LTT86L and 5973111502F are direct equivalents with Active product status. Both maintain 1.75V forward voltage, 16mcd brightness, and 660nm wavelength specifications. S7L-010LTT86L is preferred for Rohm Semiconductor supply chain continuity. The 5973111502F from Dialight provides an alternative source with 110° viewing angle specification and 662nm dominant wavelength.

For Legacy System Support (Parametric Equivalents):

SML-010LTT87 provides identical electrical and mechanical specifications to the SML-010LTT86 with matching 1.75V forward voltage and 16mcd brightness. Both parts share Not For New Designs status, making this suitable for direct legacy system maintenance only.

For New Design Transitions:

SML-012V8TT86 is an Active product offering higher brightness (63mcd) at 2.2V forward voltage within the same 1208 package. This part accommodates designs requiring increased luminous intensity. XZMDK56W from SunLED provides 79mcd brightness at 1.95V in a right-angle surface mount configuration with reduced height (1.00mm), suitable for space-constrained applications.

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can S7L-010LTT86L be used as a direct drop-in replacement for SML-010LTT86?

A: Yes. S7L-010LTT86L maintains identical package type (1208/3020 Metric), forward voltage (1.75V), brightness (16mcd), and wavelength (660nm) specifications. The part is Active status, providing improved supply availability compared to the Not For New Designs SML-010LTT86.

Q: What is the difference between SML-010LTT86 and SML-010LTT87?

A: Both parts share identical electrical specifications (1.75V, 16mcd, 660nm) and mechanical form factor. The difference is in the lens variant designation (LTT86 vs. LTT87). Both are classified as Not For New Designs. For new applications, use Active alternatives such as S7L-010LTT86L.

Q: Can SML-012V8TT86 replace SML-010LTT86 in existing designs?

A: SML-012V8TT86 is mechanically compatible (same 1208 package) but differs electrically: 2.2V forward voltage versus 1.75V, and 63mcd brightness versus 16mcd. Circuit redesign is required to accommodate the higher forward voltage. This substitution is suitable only when increased brightness is acceptable or required.

Q: What are the viewing angle differences among substitute parts?

A: SML-010LTT86 does not specify viewing angle. The 5973111502F provides 110° viewing angle. XZMDK56W offers 120° viewing angle. These differences affect light distribution characteristics and should be evaluated against application requirements.

Q: Is XZMDK56W compatible with standard 1208 footprints?

A: XZMDK56W uses a 2-SMD, No Lead package with right-angle mounting, differing from the standard 1208 flat-top configuration. While the footprint dimensions (3.00mm L x 2.00mm W) are similar, the reduced height (1.00mm vs. 1.50mm) and right-angle orientation require PCB layout modification. This part is suitable for space-constrained designs but not for direct footprint replacement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (S7L-010LTT86L, SML-012V8TT86, SML-010LTT87, 5973111502F, and XZMDK56W) are ROHS3 Compliant with EAR99 export classification, matching the original SML-010LTT86 compliance status.

Q: Which substitute offers the best supply availability?

A: S7L-010LTT86L, SML-012V8TT86, 5973111502F, and XZMDK56W all have Active product status with current inventory. S7L-010LTT86L from Rohm Semiconductor is recommended for supply chain consistency with the original manufacturer.
