SSI-LXR4815GD-600 Equivalent & Substitute Parts

Part Overview

The SSI-LXR4815GD-600 is an LED panel indicator manufactured by Lumex Opto/Components Inc. This component is a green diffused LED with wire leads designed for panel-mount applications. The part operates at 2.2V forward voltage with a maximum current rating of 20mA and features a 5mm T-1 3/4 lens form factor with a 60° viewing angle. The product is currently active and ROHS3 compliant.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for LED panel indicator applications. The primary substitute listed is the MPR5GDW12.0 from Bivar Inc., which shares the same lens size, panel cutout dimensions, and core functional characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for LED panel indicators is determined by compatibility across the following critical parameters:

Mechanical Compatibility:

• Lens size must be identical (5mm, T-1 3/4)
• Panel cutout shape and dimensions must match (Round, 0.32")
• Lens style must be compatible (Round with Domed Top)
• Termination style must be wire leads

Electrical Compatibility:

• Lamp color must be identical (Green)
• Lens transparency must be identical (Diffused)
• Forward voltage must be within acceptable circuit design tolerance
• Maximum current rating must support the application requirement
• Wavelength peak must be within the green spectrum range

Compliance:

• RoHS3 compliance required
• REACH unaffected status required

The MPR5GDW12.0 meets all mechanical compatibility requirements and maintains green diffused LED functionality. Electrical parameters show minor variations in forward voltage (2.1V vs 2.2V), maximum current (30mA vs 20mA), and viewing angle (40° vs 60°), which remain within acceptable substitution parameters for panel indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The SSI-LXR4815GD-600 and MPR5GDW12.0 are both active products with ROHS3 compliance and REACH unaffected status, making them suitable for current production applications.

Mechanical Compatibility:

Both parts share identical lens size (5mm T-1 3/4), panel cutout dimensions (0.32"), and lens style (Round with Domed Top). Panel mounting is directly compatible. Wire lead termination is present in both parts; however, lead length differs (24" vs 12"). Lead length must be evaluated based on specific application wiring requirements.

Electrical Performance:

The MPR5GDW12.0 operates at 2.1V forward voltage compared to 2.2V for the SSI-LXR4815GD-600, representing a 0.1V reduction. The substitute part supports a higher maximum current rating (30mA vs 20mA). The viewing angle is narrower (40° vs 60°), and the millicandela rating is lower (25mcd vs 30mcd). These electrical differences must be evaluated against specific circuit design parameters and application visibility requirements.

Compliance Status:

Both parts maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification, and 8541.41.0000 HTSUS code).

Frequently Asked Questions (FAQ)

Q: Can the MPR5GDW12.0 be used as a direct replacement for the SSI-LXR4815GD-600?

A: Mechanical compatibility is confirmed for panel mounting applications. Electrical parameter differences exist in forward voltage, maximum current rating, viewing angle, and brightness. Application-specific circuit design and visibility requirements must be evaluated before substitution.

Q: What is the significance of the 0.1V forward voltage difference?

A: The MPR5GDW12.0 operates at 2.1V compared to 2.2V for the SSI-LXR4815GD-600. This difference affects circuit design calculations for current-limiting resistor values. Circuits designed for 2.2V operation may require recalculation when using the 2.1V substitute part.

Q: Why does the MPR5GDW12.0 have a narrower viewing angle?

A: The substitute part has a 40° viewing angle compared to 60° for the main part. This affects the light distribution cone and may impact visibility in applications requiring wide-angle illumination. Application requirements for viewing angle must be confirmed before substitution.

Q: How does the lead length difference affect compatibility?

A: The SSI-LXR4815GD-600 features 24" wire leads while the MPR5GDW12.0 has 12" leads. Lead length must be compatible with the specific panel mounting location and wiring layout. Longer leads may be required for certain applications.

Q: Are both parts suitable for new production designs?

A: Both the SSI-LXR4815GD-600 and MPR5GDW12.0 are listed as active products with current inventory availability. Both maintain ROHS3 compliance and REACH unaffected status, making them suitable for current production applications.

Q: What packaging differences exist between these parts?

A: The SSI-LXR4815GD-600 is supplied in Bulk packaging, while the MPR5GDW12.0 is supplied in Bag packaging. Packaging format may affect inventory management and component handling procedures.
