SSI-LXH312GD-430 LED Panel Indicator Green Equivalent & Substitute Parts

Part Overview

The SSI-LXH312GD-430 is an active LED panel indicator manufactured by Lumex Opto/Components Inc. This component is a 3mm green diffused LED designed for panel-mount applications with 17-inch wire leads. The part operates at 2.1V forward voltage with a maximum current rating of 20mA and delivers 30 millicandela luminous intensity at a 565nm peak wavelength with a 60-degree viewing angle.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained within the allowed parameter specifications for this LED category. The primary substitute differs in wire lead length and maximum current rating while maintaining identical optical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSI-LXH312GD-430 is determined by strict adherence to the following critical parameters:

Electrical Parameters (Must Match):

• Forward Voltage: 2.1V
• Lamp Color: Green
• Wavelength - Peak: 565nm
• Millicandela Rating: 30mcd
• Viewing Angle: 60 degrees

Mechanical Parameters (Must Match):

• Lens Size: 3mm, T-1
• Lens Color: Green
• Lens Transparency: Diffused
• Panel Cutout Shape: Round
• Panel Cutout Dimensions: 0.17 inches (4.32mm)
• Termination Style: Wire Leads

Parameters Allowed to Vary:

• Wire Lead Length: Substitutes may have different lead lengths (6 inches to 17 inches)
• Maximum Current Rating (If): Substitutes may have higher current ratings (up to 25mA) provided the forward voltage remains 2.1V

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The SSI-LXH312GD-150 qualifies as a substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The SSI-LXH312GD-430 and SSI-LXH312GD-150 are electrically and optically equivalent components. Both parts maintain identical forward voltage (2.1V), luminous intensity (30mcd), wavelength (565nm), and viewing angle (60 degrees). Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Differentiation Factors:

The primary distinction between these parts is wire lead length. The SSI-LXH312GD-430 provides 17-inch leads, while the SSI-LXH312GD-150 provides 6-inch leads. Lead length selection depends on the physical distance between the panel mounting location and the circuit connection point.

The SSI-LXH312GD-150 has a higher maximum current rating (25mA versus 20mA). This higher rating does not affect substitution eligibility; it indicates the substitute part can safely operate at the original part's 20mA specification with additional current capacity margin.

Compliance Status:

Both parts are active products with current manufacturing status. Both carry ROHS3 compliance certification and REACH unaffected status, confirming suitability for applications requiring regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the SSI-LXH312GD-150 replace the SSI-LXH312GD-430 in my circuit?

A: Yes, the SSI-LXH312GD-150 is electrically equivalent. Both parts operate at 2.1V forward voltage and deliver 30mcd luminous intensity. The primary difference is wire lead length: 6 inches versus 17 inches. Substitution is valid if the shorter lead length accommodates your panel-to-circuit connection distance.

Q: What is the significance of the different maximum current ratings (20mA vs. 25mA)?

A: The SSI-LXH312GD-150 has a higher maximum current rating. This does not affect substitution. If your circuit operates the LED at 20mA, the substitute part's 25mA rating provides additional operational margin. Both parts are rated for the same forward voltage and will function identically in your application.

Q: Are both parts RoHS compliant?

A: Yes. Both the SSI-LXH312GD-430 and SSI-LXH312GD-150 are ROHS3 compliant and REACH unaffected. They meet current regulatory requirements for electronic component manufacturing and use.

Q: Will the substitute part fit my panel cutout?

A: Yes. Both parts have identical mechanical specifications: 3mm T-1 lens size with a 0.17-inch (4.32mm) round panel cutout. The physical mounting interface is identical. The only difference is the length of the wire leads extending from the panel.

Q: What if I need the 17-inch lead length specifically?

A: The SSI-LXH312GD-430 is the correct part for 17-inch lead requirements. The substitute SSI-LXH312GD-150 provides 6-inch leads. If lead length is a critical design parameter, use the original part number.

Q: Are both parts currently in stock?

A: Yes. The SSI-LXH312GD-430 has 821 pieces in stock. The SSI-LXH312GD-150 has 3020 pieces in stock. Both are available as new original components.

Q: Do these parts have identical optical characteristics?

A: Yes. Both parts are green diffused LEDs with 30mcd luminous intensity, 565nm peak wavelength, and 60-degree viewing angle. The optical output and light distribution are identical.
