OVM4YTX Equivalent & Substitute Parts

Part Overview

The OVM4YTX is a yellow LED indication component manufactured by TT Electronics/Optek Technology, designed for through-hole mounting applications. This discrete LED operates at 1.8V forward voltage with a dominant wavelength of 589nm and delivers 2010 millicandela at 20mA test current. The component features a TO-46-2 metal can package with a clear, domed lens.

The OVM4YTX is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing production requirements, maintenance operations, and system redesigns where this part is no longer readily available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVM4YTX is determined by the following critical parameters:

• Color and Wavelength: Yellow indication at 589nm dominant wavelength
• Electrical Performance: Forward voltage and test current characteristics
• Optical Output: Millicandela rating and viewing angle
• Mechanical Compatibility: Through-hole mounting configuration and physical dimensions
• Regulatory Compliance: RoHS3 compliance and REACH status

The substitute part 151033YS03000 (Würth Elektronik) meets the functional requirements for yellow LED indication. Both components operate in the yellow spectrum (589-592nm), maintain through-hole mounting compatibility, and satisfy RoHS3 compliance requirements. The substitute operates at 2V forward voltage with comparable optical output (2100mcd) and maintains the same test current specification (20mA).

Parameter Comparison

Engineering Selection Recommendations

The 151033YS03000 substitute part is suitable for applications requiring yellow LED indication where the OVM4YTX is no longer available. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production.

The substitute operates at 2V forward voltage compared to the original 1.8V specification. Circuit designs must accommodate this 0.2V increase in forward voltage drop. The substitute delivers higher optical output (2100mcd versus 2010mcd) and provides a wider viewing angle (30° versus 18°), which may improve visibility in certain applications.

Physical dimensions differ between the two components. The substitute features a smaller lens diameter (3.00mm versus 4.63mm) and uses a radial package configuration instead of the TO-46-2 metal can. PCB layout and mechanical mounting must be evaluated for compatibility with the substitute's physical form factor.

The substitute part is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can the 151033YS03000 directly replace the OVM4YTX without circuit modifications?

A: The substitute operates at 2V forward voltage versus the original 1.8V. Current-limiting resistor values in the circuit must be recalculated to accommodate this voltage difference. Direct pin-for-pin replacement without circuit analysis is not recommended.

Q: What are the mechanical compatibility considerations?

A: The substitute uses a 3mm radial package with a smaller lens diameter (3.00mm) compared to the original TO-46-2 metal can (4.63mm lens). PCB footprint and mechanical mounting must be redesigned. The substitute height (5.55mm maximum) is slightly greater than the original (4.79mm maximum).

Q: Are there viewing angle differences between these components?

A: Yes. The substitute provides a 30° viewing angle compared to the original 18° viewing angle. This wider angle may improve visibility but could affect optical performance in applications requiring narrow-angle indication.

Q: Do both components meet current regulatory requirements?

A: Both the OVM4YTX and 151033YS03000 are ROHS3 compliant and REACH unaffected. The substitute's active production status ensures compliance with current and future regulatory standards.

Q: What is the optical output difference?

A: The substitute delivers 2100 millicandela at 20mA test current compared to the original 2010 millicandela. This represents a 4.5% increase in brightness at the same test current.
