QL332GD LED Green Diffused 5MM Through Hole - Equivalent & Substitute Parts

Part Overview

The QL332GD is a green diffused LED indicator manufactured by onsemi, designed for through-hole mounting applications in T-1 3/4 (5mm) form factor. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing production support and design continuity. The part serves LED indication purposes in discrete radial configurations and requires alternative sourcing for new designs or production restocking.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the QL332GD is determined by the following critical parameters:

• Mounting Type: Through Hole configuration required for PCB compatibility
• Package / Case: Radial package format for standard LED lead configuration
• Lens Type: Diffused lens for uniform light distribution
• Color: Green wavelength for visual indication matching
• Form Factor Compatibility: Physical dimensions must accommodate existing PCB footprints and mechanical constraints

The substitute part 5219210F from Dialight meets these core substitution criteria through equivalent through-hole radial mounting, green diffused lens configuration, and compatible physical dimensions. While the 5219210F uses a 3mm form factor compared to the QL332GD's 5mm package, both maintain radial through-hole mounting and diffused green LED functionality suitable for LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

The 5219210F from Dialight is an active product with ROHS3 compliance, providing regulatory advantage over the obsolete, RoHS non-compliant QL332GD. Both components share identical REACH and ECCN classifications, maintaining consistent export and regulatory status.

The primary design consideration is the form factor difference: the 5219210F operates in a 3mm package with 6.00mm maximum height, compared to the QL332GD's 5mm T-1 3/4 package at 8.60mm height. This dimensional variance requires PCB footprint evaluation and mechanical clearance assessment for existing designs.

Both components maintain MSL Level 1 (Unlimited) moisture sensitivity, ensuring equivalent storage and handling requirements. The 5219210F's active product status ensures long-term availability and supply chain continuity, addressing the obsolescence risk of the QL332GD.

Frequently Asked Questions (FAQ)

Q: Can the 5219210F directly replace the QL332GD without PCB modifications?

A: Direct replacement requires PCB footprint compatibility assessment. The 5219210F uses a 3mm form factor versus the QL332GD's 5mm package. While both employ radial through-hole mounting, the different lens diameters and lead spacing may necessitate footprint adjustments.

Q: What are the key electrical differences between these parts?

A: The QL332GD specifications for voltage, current, and wavelength are not provided in the original documentation. The 5219210F operates at 2.1V forward voltage with 10mA test current and 568nm dominant wavelength. Electrical compatibility must be confirmed against the QL332GD's original circuit design parameters.

Q: Why is RoHS compliance important for this substitution?

A: The QL332GD is RoHS non-compliant while the 5219210F is ROHS3 compliant. For new designs or production in regulated markets, ROHS3 compliance is mandatory. Existing designs using RoHS non-compliant components may continue with the QL332GD if regulatory exemptions apply.

Q: Are there any supply chain advantages to using the 5219210F?

A: Yes. The 5219210F is an active product with 4730 units in stock, compared to the QL332GD's obsolete status with 784 units available. Active product status ensures ongoing availability and manufacturing support.

Q: Do both parts share the same moisture sensitivity requirements?

A: Yes. Both the QL332GD and 5219210F are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity limitations for storage, handling, or soldering processes.
