QL335IC LED Red Clear 5MM T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The QL335IC is a red LED indicator in a 5MM T-1 3/4 through-hole package manufactured by onsemi. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The through-hole radial configuration and 5MM form factor are standard for LED indication applications requiring discrete component placement on PCBs with traditional mounting methods.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the QL335IC is based on the following critical parameters:

• Mounting Type: Through Hole radial configuration required
• Package Form Factor: T-1 3/4 (5mm) lens diameter standard
• Physical Height: Maximum 8.60mm to ensure PCB clearance compatibility
• Electrical Classification: Red LED indication category
• Environmental Compliance: MSL 1 rating for unlimited moisture exposure

The SSL-LX5093IT from Lumex Opto/Components Inc. meets these substitution criteria as an active product with identical mechanical specifications and compatible electrical characteristics for red LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX5093IT is a direct mechanical substitute for the obsolete QL335IC. Both components share identical through-hole radial mounting, T-1 3/4 package form factor, and 8.60mm maximum height. The SSL-LX5093IT offers the advantage of active product status, ensuring long-term availability and supply chain stability.

For applications requiring RoHS compliance, the SSL-LX5093IT meets ROHS3 standards, whereas the QL335IC is RoHS non-compliant. Both components maintain MSL 1 rating and EAR99 export classification. The SSL-LX5093IT provides specified electrical parameters (2V forward voltage, 20mA test current, 635nm peak wavelength) suitable for standard red LED indication circuits.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX5093IT directly replace the QL335IC in existing PCB designs?

A: Yes. Both components use identical through-hole radial mounting, T-1 3/4 package geometry, and 8.60mm maximum height. No PCB layout modifications are required for mechanical compatibility.

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

A: The QL335IC specifications are not fully documented in available data. The SSL-LX5093IT specifies 2V forward voltage, 20mA test current, and 635nm peak wavelength. Circuit designers should verify these parameters are compatible with existing current-limiting resistor values and power supply configurations.

Q: Does the SSL-LX5093IT meet RoHS requirements?

A: Yes. The SSL-LX5093IT is ROHS3 compliant, whereas the QL335IC is RoHS non-compliant. This makes the SSL-LX5093IT suitable for applications with RoHS compliance mandates.

Q: Are there any moisture sensitivity concerns with the SSL-LX5093IT?

A: No. Both components carry MSL 1 rating, indicating unlimited moisture exposure tolerance. Standard PCB assembly and storage practices apply.

Q: What is the availability status of the SSL-LX5093IT?

A: The SSL-LX5093IT is an active product with current manufacturing support, ensuring reliable long-term supply compared to the obsolete QL335IC.
