LED RED CLEAR 1206 SMD 7010X1 Equivalent & Substitute Parts

Part Overview

The 7010X1 is a red LED indication component in 1206 (3016 Metric) surface mount package manufactured by Visual Communications Company (VCC). This discrete LED operates at 1.7V forward voltage with a 20mA test current and delivers 6mcd luminous intensity through a clear, colorless rectangular lens with flat top design. The component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing production and maintenance applications. Substitute parts must maintain compatibility across critical electrical parameters, mechanical dimensions, and mounting characteristics to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7010X1 are identified based on strict alignment with the following critical parameters:

Mandatory Matching Criteria:

• Package / Case: 1206 (3016 Metric) surface mount configuration
• Mounting Type: Surface Mount
• Color: Red
• Lens Transparency: Clear
• Voltage - Forward (Vf) (Typ): 1.7V to 2.0V range (within typical circuit tolerance)
• Current - Test: 20mA operating point
• RoHS3 Compliance: Required for regulatory alignment

Acceptable Variation Parameters:

• Millicandela Rating: Variations permitted within application visibility requirements
• Viewing Angle: Variations acceptable based on circuit application context
• Wavelength - Peak: Red spectrum range (640nm to 660nm) acceptable
• Lens Style: Both rectangular and round configurations compatible with 1206 footprint
• Height (Max): Variations within 1.10mm to 1.51mm acceptable for standard PCB assembly

The three identified substitute parts (5973111402F, 5973111407F, and SML-LX1206IC-TR) satisfy all mandatory matching criteria while demonstrating acceptable variations in secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SML-LX1206IC-TR (Lumex Opto/Components Inc.)

The SML-LX1206IC-TR is the preferred substitute for new designs and ongoing production applications. This component maintains active product status, ensuring long-term availability and supply chain stability. It satisfies all mandatory electrical parameters with 2V forward voltage (within acceptable circuit tolerance versus 1.7V original specification) and 20mA test current. The component delivers 9mcd luminous intensity, providing adequate brightness for indication applications. RoHS3 compliance and improved moisture sensitivity rating (MSL 3, 168 hours versus MSL 4, 72 hours) enhance manufacturing reliability. The wider 130° viewing angle accommodates diverse mounting orientations. Height reduction to 1.10mm maximum improves PCB assembly clearance margins.

Secondary Recommendations: 5973111407F and 5973111402F (Dialight)

Both Dialight components (5973111407F and 5973111402F) provide direct electrical equivalence with identical 1.7V forward voltage and 20mA test current. These parts maintain exact dimensional compatibility with the original 7010X1 footprint (3.00mm L x 1.50mm W). The 33.6mcd luminous intensity provides enhanced brightness for visibility-critical applications. However, both components carry obsolete product status, limiting long-term availability. The 5973111407F in Tape & Reel packaging offers superior handling for automated assembly compared to the 5973111402F strip format.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements equivalent to the original 7010X1 specification. Moisture sensitivity improvements in Dialight and Lumex components (MSL 3 versus MSL 4) reduce risk during storage and assembly processes.

Frequently Asked Questions (FAQ)

Q1: Can the SML-LX1206IC-TR replace the 7010X1 directly in existing circuits?

The SML-LX1206IC-TR operates at 2V forward voltage compared to the 7010X1's 1.7V specification. This 0.3V difference requires circuit verification. In series resistor-limited designs, the higher forward voltage reduces LED current slightly, requiring resistor adjustment to maintain 20mA test current. Direct substitution without circuit modification is not recommended for precision applications.

Q2: What is the difference between the Dialight 5973111402F and 5973111407F?

Both components are electrically and mechanically identical. The primary difference is packaging format: 5973111402F uses Strip packaging suitable for manual or semi-automated assembly, while 5973111407F uses Tape & Reel (TR) format optimized for high-speed automated pick-and-place equipment. Select based on assembly process requirements.

Q3: Why do the Dialight substitutes show higher millicandela ratings (33.6mcd) than the original 7010X1 (6mcd)?

The Dialight components deliver greater luminous intensity at identical 20mA test current due to superior LED die efficiency and optical design. Higher brightness provides enhanced visibility for indication applications. Circuit designs using current-limiting resistors will automatically accommodate this brightness increase without modification.

Q4: Are there viewing angle differences between substitute parts?

Yes. The 7010X1 and Dialight substitutes specify 70° viewing angle, while the SML-LX1206IC-TR provides 130° viewing angle. The wider angle in the Lumex component allows visibility from greater off-axis positions. For applications requiring narrow-angle indication, the 70° parts maintain original specifications.

Q5: What is the significance of the 1206 (3216 Metric) designation for the SML-LX1206IC-TR?

The SML-LX1206IC-TR uses 3216 Metric dimensions (3.20mm length versus 3.00mm standard 1206), representing a slight length increase. The component remains compatible with standard 1206 PCB footprints due to typical pad spacing tolerances, but verification with PCB layout is recommended for high-density designs.

Q6: How do moisture sensitivity levels affect component selection?

The original 7010X1 specifies MSL 4 (72-hour floor life), while all substitutes provide MSL 3 (168-hour floor life). MSL 3 rating allows extended handling time after moisture absorption, reducing risk of solder joint defects during reflow assembly. This improvement enhances manufacturing reliability for both new production and field repairs.

Q7: Which substitute part offers the best long-term availability?

The SML-LX1206IC-TR carries active product status, indicating ongoing manufacturing and distribution support. The Dialight components (5973111402F and 5973111407F) are obsolete, similar to the original 7010X1, limiting future availability. For applications requiring extended production runs or future maintenance, the Lumex component provides superior supply chain continuity.

Q8: Can substitute parts be mixed within the same circuit board?

Mixing substitute parts is not recommended. While all components satisfy the same functional requirements, differences in luminous intensity (6mcd to 33.6mcd range) and viewing angles (70° to 130°) create visual inconsistency in multi-LED indicator arrays. Standardize on a single substitute part across all positions for uniform appearance and performance.
