SSL-LX3044ID-5V Equivalent & Substitute Parts

Part Overview

The SSL-LX3044ID-5V is a red diffused LED indicator manufactured by Lumex Opto/Components Inc., designed for through-hole mounting in 5V discrete applications. This T-1 form factor component features a 3mm round domed lens with 6mcd brightness rating and 60° viewing angle. The part is currently in active product status with 708 units in stock.

Substitute parts become necessary when the main part reaches end-of-life status, inventory depletion, or when design requirements permit alternative electrical specifications. The SSL-LX3044HD represents a parametric equivalent within the same product family, though with different electrical characteristics and obsolete status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LX3044ID-5V is determined by strict alignment of the following parameters:

Mandatory Matching Parameters:

• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Lens Color: Red
• Lens Transparency: Diffused
• Mounting Type: Through Hole
• Package / Case: Radial
• Height (Max): 4.60mm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Typ): May vary based on circuit design requirements
• Millicandela Rating: 6mcd (fixed for this product family)
• Wavelength - Peak: May vary within red spectrum (635nm to 700nm range)
• Viewing Angle: 60° (fixed for this product family)
• Product Status: Active or Obsolete (both acceptable for substitution purposes)

The SSL-LX3044HD meets all mandatory matching parameters and represents a valid parametric equivalent, with the primary difference being forward voltage specification (2V vs. 5V) and peak wavelength (700nm vs. 635nm).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: SSL-LX3044ID-5V

The SSL-LX3044ID-5V is the recommended choice for new designs and applications requiring active product status. This part maintains current manufacturing support, has adequate inventory availability (708 units), and carries full ROHS3 compliance and REACH unaffected status. The 5V forward voltage specification aligns with standard logic-level circuit designs.

Alternative Selection: SSL-LX3044HD

The SSL-LX3044HD is classified as obsolete and should be selected only when existing inventory constraints or legacy system requirements necessitate its use. While this part meets all mandatory mechanical and optical parameters, its obsolete status indicates discontinued manufacturing. The 2V forward voltage specification requires circuit design accommodation and differs significantly from the main part. This substitute is suitable only for applications where the lower forward voltage is compatible with existing power supply and current-limiting circuit design.

Compliance Considerations

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for EU and international markets. Moisture sensitivity level 1 (unlimited) indicates no special storage or handling requirements for either part.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3044HD be used as a direct drop-in replacement for SSL-LX3044ID-5V?

A: Mechanical and optical compatibility is confirmed. However, the forward voltage difference (2V vs. 5V) requires circuit design verification. Direct substitution without circuit modification is not recommended.

Q: What is the primary difference between these two parts?

A: The SSL-LX3044ID-5V operates at 5V forward voltage with 635nm peak wavelength, while the SSL-LX3044HD operates at 2V forward voltage with 700nm peak wavelength. Both share identical mechanical form factor, lens specifications, and brightness rating.

Q: Why is SSL-LX3044HD listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This part should not be selected for new designs. It remains available only through existing inventory channels.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level 1 (unlimited) ratings.

Q: What mounting considerations apply to both parts?

A: Both parts use through-hole radial mounting with identical 4.60mm maximum height. PCB footprint and lead spacing are compatible between the two parts.

Q: How does the wavelength difference affect application suitability?

A: The wavelength difference (635nm vs. 700nm) represents a shift within the red spectrum. The SSL-LX3044ID-5V produces a more orange-red appearance, while the SSL-LX3044HD produces a deeper red appearance. Application suitability depends on visual indication requirements and human perception factors.
