Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSF-LXH303LGD are determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Color: Green (565nm peak wavelength)
• Current Rating: 20mA
• Millicandela Rating: 30mcd
• Viewing Angle: 60°

Mechanical Parameters:

• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole, Right Angle

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts are grouped into two categories based on voltage rating variance:

Category 1 (2.2V Rating): SSF-LXH303GD Category 2 (2.1V Rating): SSF-LXH103GD, SSF-LXH4RAGD

All substitute parts maintain identical optical, mechanical, and compliance characteristics. Voltage rating differences of 0.1V fall within acceptable tolerance for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between substitute parts is determined by voltage rating requirements and packaging availability:

SSF-LXH303GD is the primary substitute for SSF-LXH303LGD, offering identical voltage rating (2.2V) and all electrical and mechanical specifications. This part is recommended when direct parameter matching is required.

SSF-LXH103GD and SSF-LXH4RAGD operate at 2.1V, representing a 0.1V reduction from the main part. These parts are suitable for applications where the lower voltage rating is compatible with circuit design parameters. Both parts maintain all other electrical and mechanical characteristics.

All substitute parts are manufactured by Lumex Opto/Components Inc. and carry equivalent compliance certifications, ensuring regulatory and environmental standards alignment.

Frequently Asked Questions (FAQ)

Q: Can SSF-LXH303GD directly replace SSF-LXH303LGD?

A: Yes. SSF-LXH303GD is a direct substitute with identical electrical specifications (2.2V, 20mA, 30mcd), optical characteristics (565nm green, 60° viewing angle, diffused tinted lens), and mechanical configuration (3mm T-1 through-hole right-angle mount). Both parts are ROHS3 compliant and carry MSL 1 rating.

Q: What is the difference between the 2.2V and 2.1V rated parts?

A: SSF-LXH303LGD and SSF-LXH303GD operate at 2.2V, while SSF-LXH103GD and SSF-LXH4RAGD operate at 2.1V. The 0.1V difference reflects manufacturing variants within the same product family. All other parameters—current, luminous intensity, viewing angle, lens type, and mounting configuration—remain identical.

Q: Are packaging differences significant for substitution?

A: Packaging format (tape, bulk, or reel) does not affect electrical or mechanical compatibility. Substitute parts may arrive in different packaging configurations. Verify packaging requirements with procurement specifications before ordering.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts listed are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level). Compliance certifications are equivalent across all parts.

Q: Can I use SSF-LXH103GD or SSF-LXH4RAGD in a circuit designed for 2.2V operation?

A: The 2.1V rated parts operate at a lower voltage threshold. Circuit compatibility depends on the specific design parameters and voltage tolerance of the application. Verify that the 0.1V reduction does not impact circuit performance or LED brightness requirements.

Q: What is the inventory status of substitute parts?

A: SSF-LXH303GD has 26,751 units in stock. SSF-LXH103GD has 19,351 units in stock. SSF-LXH4RAGD has 2,971 units in stock. All parts are new original stock from Lumex Opto/Components Inc.
