SSI-LXR3816SYD-150 LED Panel Indicator Yellow - Equivalent & Substitute Parts

Part Overview

The SSI-LXR3816SYD-150 is an active yellow LED panel indicator manufactured by Lumex Opto/Components Inc. This component is a diffused 5mm T-1 3/4 LED with wire leads designed for panel-mount applications requiring visual indication. The part operates at 2.1V forward voltage with a maximum current rating of 20mA, delivering 100mcd luminous intensity at a 60° viewing angle with a 590nm peak wavelength.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers while accommodating application-specific requirements such as lens transparency, viewing angle, and lead length variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSI-LXR3816SYD-150 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Lamp color and lens color: Yellow (590nm wavelength range)
• Lens size and style: 5mm T-1 3/4 round domed top
• Panel cutout shape and dimensions: Round 0.32" (8.13mm)
• Termination style: Wire leads
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Allowable Variation Parameters:

• Forward voltage (Vf): 2.0V to 2.1V range acceptable for series circuit applications
• Maximum current (If): 20mA to 30mA range acceptable depending on circuit design
• Lens transparency: Diffused or clear acceptable based on application visibility requirements
• Viewing angle: 35° to 60° acceptable depending on panel mounting geometry
• Millicandela rating: 40mcd to 100mcd acceptable based on brightness requirements
• Lead length: 6" to 12" acceptable based on panel depth and routing requirements

The MPC5YTW12.0 from Bivar Inc. qualifies as a substitute part based on matching mandatory parameters while operating within allowable variation ranges for electrical and optical characteristics.

Parameter Comparison

Engineering Selection Recommendations

SSI-LXR3816SYD-150 Selection Criteria:

• Applications requiring diffused light distribution for wider light scatter
• Designs requiring 100mcd brightness output
• Designs requiring 60° viewing angle for broad visibility
• Panel depths accommodating 6" (152.40mm) wire leads
• Designs operating at 2.1V forward voltage with 20mA maximum current

MPC5YTW12.0 Selection Criteria:

• Applications where clear lens transparency is acceptable or preferred
• Designs tolerating 40mcd brightness output
• Designs with 35° viewing angle requirements or narrower beam focus
• Panel depths accommodating 12" (304.80mm) wire leads
• Designs where 2V forward voltage and 30mA maximum current rating are compatible

Regulatory Compliance: Both parts maintain ROHS3 compliance and EAR99 export classification. Both are classified under HTSUS 8541.41.0000. Active product status confirms ongoing manufacturer support and availability.

Circuit Design Considerations: When substituting MPC5YTW12.0 for SSI-LXR3816SYD-150, circuit current limiting must accommodate the 30mA maximum rating of the substitute part. The 0.1V voltage difference (2.1V vs 2V) is negligible in series circuit applications. Lead length difference requires panel routing assessment.

Frequently Asked Questions (FAQ)

Q: Can MPC5YTW12.0 directly replace SSI-LXR3816SYD-150 in existing designs?

A: Direct replacement requires verification of three factors: (1) Circuit current limiting capability for the 30mA maximum rating, (2) Acceptance of reduced brightness (40mcd vs 100mcd), and (3) Acceptance of narrower viewing angle (35° vs 60°). Panel routing must accommodate the longer 12" leads versus 6" leads. Lens transparency difference (clear vs diffused) affects light distribution pattern.

Q: What is the significance of the lens transparency difference?

A: Diffused lenses scatter light over a wider area with reduced peak intensity in the direct viewing direction. Clear lenses concentrate light with higher intensity in the direct viewing direction. Application visibility requirements determine which is appropriate.

Q: Are there electrical compatibility issues between these parts?

A: The 0.1V forward voltage difference (2.1V vs 2V) is within normal LED manufacturing tolerance and does not create compatibility issues in series circuit applications. The substitute part's higher 30mA maximum current rating requires circuit design verification to ensure current limiting does not exceed 20mA if the original design specified this limit.

Q: How do the viewing angles affect panel mounting?

A: The 60° viewing angle of SSI-LXR3816SYD-150 provides visibility across a wider horizontal and vertical range from the panel surface. The 35° viewing angle of MPC5YTW12.0 provides visibility in a narrower cone, requiring more direct line-of-sight to the LED. Panel mounting angle and operator viewing position determine which is appropriate.

Q: What is the impact of different lead lengths?

A: SSI-LXR3816SYD-150 provides 6" leads suitable for panels with standard depth. MPC5YTW12.0 provides 12" leads suitable for deeper panels or applications requiring extended routing distance. Lead length does not affect electrical performance but affects physical installation feasibility.

Q: Are both parts actively manufactured?

A: Yes. Both SSI-LXR3816SYD-150 and MPC5YTW12.0 maintain active product status with current manufacturer support and availability.
