SSI-LXR1612GD-250 Equivalent & Substitute Parts

Part Overview

The SSI-LXR1612GD-250 is an LED panel indicator manufactured by Lumex Opto/Components Inc. This green diffused LED features a 3mm T-1 lens form factor with wire leads measuring 9.8 inches (248.92mm). The component operates at a forward voltage of 2.2V with a maximum current rating of 20mA and delivers 30 millicandela of luminous intensity at a 565nm peak wavelength with a 60° viewing angle.

The product maintains Active status with full ROHS3 compliance and REACH unaffected classification. Substitute parts are identified to address inventory availability, lead time requirements, or specific application constraints while maintaining functional compatibility within acceptable electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSI-LXR1612GD-250 is determined by the following critical parameters:

Mechanical Compatibility:

• Lens form factor: 3mm T-1 round with domed top
• Panel cutout shape and dimensions: Round, 0.24 inches (6.20mm nominal)
• Termination style: Wire leads

Electrical Compatibility:

• Lamp color: Green
• Lens transparency: Diffused
• Forward voltage range: 2.1V to 2.2V (within typical LED tolerance)
• Maximum current: 20mA to 30mA (circuit design dependent)
• Peak wavelength: 565nm to 568nm (green spectrum)

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status required
• ECCN and HTSUS classification alignment

The MPR3GDW12.0 from Bivar Inc. qualifies as a substitute based on matching mechanical form factor, green diffused lens specification, compatible electrical ratings, and equivalent regulatory compliance. Variations in viewing angle (60° versus 35°), millicandela output (30mcd versus 25mcd), and wire lead length (9.8" versus 12") represent design trade-offs that must be evaluated within specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (SSI-LXR1612GD-250): Select the Lumex SSI-LXR1612GD-250 when the original specification parameters are required, including the 60° viewing angle and 30mcd brightness output. This part maintains Active product status with full ROHS3 compliance and REACH unaffected classification. Current inventory of 936 pieces supports immediate availability.

Substitute Selection (MPR3GDW12.0): The Bivar MPR3GDW12.0 serves as a functional substitute when inventory constraints or lead time requirements necessitate an alternative source. This part maintains identical mechanical form factor, green diffused lens specification, and regulatory compliance (ROHS3, REACH unaffected, EAR99, HTSUS 8541.41.0000). The 0.1V forward voltage difference (2.1V versus 2.2V) falls within standard LED manufacturing tolerance and does not require circuit redesign. Current inventory of 1463 pieces provides extended availability.

Application-Specific Considerations: The MPR3GDW12.0 exhibits a narrower 35° viewing angle compared to the 60° specification of the SSI-LXR1612GD-250, resulting in a more directional light output. The 5mcd reduction in brightness (25mcd versus 30mcd) may impact visibility in high-ambient-light environments. The 3.08-inch longer wire lead length (12" versus 9.8") requires evaluation of panel routing and assembly constraints. Circuit current limiting must not exceed 20mA to maintain compatibility with the SSI-LXR1612GD-250 design envelope.

Frequently Asked Questions (FAQ)

Q: Can the MPR3GDW12.0 be used as a direct drop-in replacement for the SSI-LXR1612GD-250?

A: The MPR3GDW12.0 is mechanically compatible and electrically functional as a substitute. However, it is not a direct drop-in replacement due to three design differences: (1) narrower 35° viewing angle versus 60°, (2) lower 25mcd brightness versus 30mcd, and (3) longer 12" wire leads versus 9.8". These differences must be evaluated within the specific application context.

Q: What is the forward voltage difference between these parts, and does it affect circuit design?

A: The SSI-LXR1612GD-250 operates at 2.2V while the MPR3GDW12.0 operates at 2.1V, a 0.1V difference. This variation falls within standard LED manufacturing tolerance and does not require circuit redesign. Existing current-limiting resistor values remain valid for both parts.

Q: Are both parts compliant with environmental and trade regulations?

A: Yes. Both the SSI-LXR1612GD-250 and MPR3GDW12.0 are ROHS3 compliant, REACH unaffected, classified as EAR99, and assigned HTSUS code 8541.41.0000. They meet identical regulatory requirements for environmental and trade purposes.

Q: How does the viewing angle difference affect application suitability?

A: The SSI-LXR1612GD-250 provides a 60° viewing angle, delivering visible light output across a wider field. The MPR3GDW12.0 provides a 35° viewing angle, concentrating light output in a narrower cone. Applications requiring wide-angle visibility (such as status indicators visible from multiple positions) should retain the SSI-LXR1612GD-250. Applications with fixed viewing positions may tolerate the narrower angle of the MPR3GDW12.0.

Q: What is the significance of the 5mcd brightness difference?

A: The SSI-LXR1612GD-250 delivers 30mcd while the MPR3GDW12.0 delivers 25mcd. This 5mcd reduction represents approximately 17% lower luminous intensity. In low-ambient-light environments, this difference may be imperceptible. In high-ambient-light environments or applications requiring maximum visibility, the higher brightness of the SSI-LXR1612GD-250 is preferred.

Q: Do the different wire lead lengths affect mechanical assembly?

A: The SSI-LXR1612GD-250 features 9.8-inch wire leads while the MPR3GDW12.0 features 12-inch wire leads, a 3.08-inch difference. Longer leads provide additional routing flexibility but may require different panel mounting hole positioning or wire management strategies. Assembly procedures must accommodate the longer lead length of the MPR3GDW12.0.

Q: What is the current rating difference, and how should it be handled?

A: The SSI-LXR1612GD-250 is rated for 20mA maximum current while the MPR3GDW12.0 is rated for 30mA maximum current. When substituting the MPR3GDW12.0, circuit current limiting must not exceed 20mA to maintain compatibility with the original design envelope and ensure consistent brightness output.

Q: Are there packaging differences between these parts?

A: The SSI-LXR1612GD-250 is supplied in standard packaging while the MPR3GDW12.0 is supplied in bag packaging. This difference affects receiving, storage, and handling procedures but does not impact electrical or mechanical performance.
