SSL-LX3044SRD-12V Equivalent & Substitute Parts

Part Overview

The SSL-LX3044SRD-12V is an active red LED indication component manufactured by Lumex Opto/Components Inc. This through-hole T-1 3mm diffused lens LED operates at 12V forward voltage and delivers 30 millicandela brightness with a 60° viewing angle. The component is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when addressing specific application requirements including forward voltage compatibility, current specifications, wavelength characteristics, or inventory availability across manufacturing batches and packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LX3044SRD-12V is determined by strict alignment across the following critical parameters:

Mechanical Compatibility Parameters:

• Lens size: 3mm, T-1 form factor
• Mounting type: Through hole radial configuration
• Physical height: 4.60mm maximum
• Lens style: Round with domed top
• Lens transparency: Diffused

Optical Parameters:

• Color: Red
• Millicandela rating: 30mcd
• Viewing angle: 60°

Electrical Parameters:

• Forward voltage (Vf): Determines circuit compatibility and current-limiting requirements
• Peak wavelength: Affects visual appearance and application-specific detection requirements

Compliance Parameters:

• RoHS3 compliance status
• MSL rating: 1 (Unlimited)
• REACH status: Unaffected

The substitute parts SSL-LX3044ID and SSL-LX3044LID maintain identical mechanical, optical, and compliance characteristics. However, both substitutes operate at 2V forward voltage with 20mA test current and 635nm peak wavelength, representing a different electrical operating class within the same physical form factor and base product family.

Parameter Comparison

Engineering Selection Recommendations

SSL-LX3044SRD-12V (Primary Part): Select this part for applications requiring 12V forward voltage operation. This configuration eliminates the need for external current-limiting resistors in 12V direct-drive circuits. The 660nm peak wavelength provides standard red LED visual characteristics. All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, suitable for standard industrial and consumer applications.

SSL-LX3044ID (Substitute - High Inventory): This substitute operates at 2V forward voltage with 20mA test current specification. Selection requires external current-limiting circuit design. Peak wavelength of 635nm produces a slightly different red hue compared to the primary part. Inventory availability is 24,170 pieces in bulk packaging. Electrical operating class differs fundamentally from the primary part; circuit redesign is necessary for substitution.

SSL-LX3044LID (Substitute - Limited Inventory): This substitute shares identical electrical specifications with SSL-LX3044ID (2V forward voltage, 20mA test current, 635nm peak wavelength). Inventory availability is 3,800 pieces in bulk packaging. Selection follows the same circuit design requirements as SSL-LX3044ID. Differentiation from SSL-LX3044ID is limited to packaging configuration and inventory status.

All three parts maintain active product status and full regulatory compliance across ROHS3, REACH, and MSL classifications.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3044ID or SSL-LX3044LID be used as direct replacements for SSL-LX3044SRD-12V without circuit modification?

A: No. The substitute parts operate at 2V forward voltage compared to the primary part's 12V specification. Direct substitution requires complete circuit redesign to accommodate the different electrical operating class and current requirements.

Q: What is the primary difference between SSL-LX3044ID and SSL-LX3044LID?

A: Both parts share identical electrical and optical specifications (2V forward voltage, 20mA test current, 30mcd brightness, 60° viewing angle, 635nm peak wavelength, 3mm T-1 form factor). The differentiation is packaging configuration (bulk) and inventory availability (24,170 pieces versus 3,800 pieces respectively).

Q: Does the wavelength difference between 660nm and 635nm affect mechanical compatibility?

A: No. Wavelength differences do not affect mechanical compatibility. Both the primary part (660nm) and substitute parts (635nm) maintain identical physical dimensions, lens style, mounting configuration, and form factor. Wavelength differences affect only visual color perception and optical detection characteristics.

Q: Are all three parts suitable for applications requiring ROHS3 compliance?

A: Yes. SSL-LX3044SRD-12V, SSL-LX3044ID, and SSL-LX3044LID all maintain ROHS3 compliance status. All parts are also REACH unaffected and carry unlimited moisture sensitivity rating (MSL 1).

Q: What packaging configurations are available?

A: SSL-LX3044SRD-12V is supplied in standard packaging. SSL-LX3044ID and SSL-LX3044LID are supplied in bulk packaging configuration.

Q: Can these parts be used interchangeably in the same PCB layout?

A: Mechanical and mounting compatibility is identical across all three parts (through-hole radial T-1 3mm form factor, 4.60mm maximum height). However, electrical circuit design must account for the 12V versus 2V forward voltage difference. PCB layout compatibility exists; circuit design compatibility requires evaluation based on application requirements.
