SSF-LXH240GGD-RP LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The SSF-LXH240GGD-RP is a dual-level green LED circuit board indicator manufactured by Lumex Opto/Components Inc. This component is classified as an active product and is designed for through-hole, right-angle mounting applications requiring dual green LED outputs. The part is ROHS3 compliant and REACH unaffected, making it suitable for regulated electronic assemblies. Equivalent and substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing options that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSF-LXH240GGD-RP are identified based on strict electrical and mechanical compatibility criteria. The following parameters define the substitution scope:

Critical Matching Parameters:

• Color: Green (x 2)
• Configuration: 2 High
• Wavelength - Peak: 565nm
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole, Right Angle
• Voltage Rating: 2.2V
• Lens Style: Round with Domed Top

Allowable Variation Parameters:

• Current Rating: Substitute parts may operate at higher current ratings (up to 25mA) provided the circuit design accommodates the increased power consumption
• Millicandela Rating: Substitute parts may have different brightness levels (30mcd to 40mcd range) depending on lens tinting and optical properties
• Viewing Angle: Substitute parts may have different viewing angles (40° to 60°) based on lens design
• Lens Type: Substitute parts may include tinted diffused variants, which maintain optical diffusion while altering spectral characteristics

The WP934CA/2GD-90 manufactured by Kingbright meets all critical matching parameters and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the SSF-LXH240GGD-RP and WP934CA/2GD-90 are active products with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. Selection between these parts should be based on the following factors:

SSF-LXH240GGD-RP (Lumex Opto/Components Inc.):

• Specified for 20mA operation with 40mcd brightness output
• 60° viewing angle provides wider light distribution
• Standard diffused lens without tinting

WP934CA/2GD-90 (Kingbright):

• Specified for 25mA operation with 30mcd brightness output
• 40° viewing angle provides narrower light distribution
• Tinted diffused lens alters spectral characteristics
• Higher current rating requires circuit design verification

Both parts maintain identical voltage ratings (2.2V), lens size (3mm, T-1), mounting configuration (through-hole, right-angle), and dual-level green LED architecture. Circuit designs operating at 20mA or below can use either part. Designs requiring higher current capacity or narrower viewing angles may benefit from the WP934CA/2GD-90. Designs requiring maximum brightness or wider light distribution should prioritize the SSF-LXH240GGD-RP.

Frequently Asked Questions (FAQ)

Q: Can the WP934CA/2GD-90 be used as a direct replacement for the SSF-LXH240GGD-RP in existing circuit designs?

A: The WP934CA/2GD-90 is mechanically and electrically compatible for through-hole, right-angle mounting applications. However, circuit designs must accommodate the 25mA current rating of the substitute part. If the original design operates at exactly 20mA, the substitute part will draw 25% more current. Verify that current-limiting resistors and power supply capacity support this increased draw.

Q: What are the optical differences between these two parts?

A: The SSF-LXH240GGD-RP provides 40mcd brightness with a 60° viewing angle using a standard diffused lens. The WP934CA/2GD-90 provides 30mcd brightness with a 40° viewing angle using a tinted diffused lens. The tinting in the substitute part reduces brightness but may alter color perception. Applications requiring maximum brightness or wide-angle visibility should use the Lumex part.

Q: Are both parts suitable for regulated electronic assemblies?

A: Yes. Both the SSF-LXH240GGD-RP and WP934CA/2GD-90 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for controlled electronic products.

Q: What is the significance of the "2 High" configuration?

A: The "2 High" configuration indicates that this component contains two LED elements stacked vertically within a single 3mm package. Both parts maintain this dual-level architecture, ensuring functional equivalence in applications designed for dual-output LED indicators.

Q: Can these parts be used interchangeably in terms of packaging?

A: The SSF-LXH240GGD-RP is specified with standard packaging, while the WP934CA/2GD-90 is supplied in bulk packaging. Both parts use identical through-hole, right-angle mounting interfaces and 3mm T-1 lens form factors, making them mechanically interchangeable on circuit boards. Packaging differences affect only storage and handling, not circuit board integration.
