OVM4BTXV Equivalent & Substitute Parts

Part Overview

The OVM4BTXV is a blue LED indication component manufactured by TT Electronics/Optek Technology, featuring a 465nm dominant wavelength and 2260mcd brightness rating in a TO-46-2 through-hole package. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The component operates at 2.6V forward voltage with a 20mA test current and provides an 18° viewing angle in a compact metal can configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVM4BTXV is determined by the following critical parameters:

• Color specification (Blue)
• Through-hole mounting configuration
• Wavelength range compatibility (465nm dominant)
• Brightness level (2260mcd minimum acceptable range)
• Forward voltage operating range (2.6V nominal)
• Test current specification (20mA)
• Regulatory compliance (RoHS, REACH, ECCN)

The C503B-BCN-CU0W0452-030 qualifies as a substitute based on matching color, mounting type, wavelength proximity, and regulatory compliance. Variations in lens size, package form factor, and brightness rating reflect the transition from TO-46 metal can to standard 5mm radial through-hole technology while maintaining functional equivalence for indication applications.

Parameter Comparison

Engineering Selection Recommendations

The C503B-BCN-CU0W0452-030 is an active production substitute for the obsolete OVM4BTXV. Both components maintain identical regulatory compliance classifications (RoHS, REACH, ECCN EAR99) and moisture sensitivity levels (MSL 1 - Unlimited).

The substitute exhibits higher brightness (2850mcd vs 2260mcd) and wider viewing angle (30° vs 18°), which are advantageous for indication applications. The forward voltage increase from 2.6V to 3.2V requires circuit design verification to ensure compatibility with existing current-limiting resistor networks and power supply specifications. The wavelength shift from 465nm to 470nm remains within the blue spectrum and is imperceptible to human vision in indication applications.

Physical form factor changes from TO-46-2 metal can to standard 5mm radial package necessitate PCB layout and mechanical mounting modifications. The substitute's larger lens diameter (5.00mm vs 4.63mm) and greater height (10.10mm vs 4.79mm) must be evaluated against available board space and enclosure clearances.

Frequently Asked Questions (FAQ)

Q: Can the C503B-BCN-CU0W0452-030 directly replace the OVM4BTXV without circuit modifications?

A: Direct replacement requires circuit evaluation. The 0.6V forward voltage increase (2.6V to 3.2V) affects current-limiting resistor calculations. Existing resistor values designed for 2.6V operation will produce different current through the 3.2V substitute. Recalculation of series resistance is necessary to maintain proper brightness and component lifespan.

Q: Are there mechanical compatibility concerns?

A: Yes. The OVM4BTXV uses a TO-46-2 metal can package with 4.63mm lens diameter and 4.79mm maximum height. The C503B-BCN-CU0W0452-030 is a standard 5mm radial package with 10.10mm maximum height. PCB footprint, lead spacing, and enclosure clearance must be verified before substitution.

Q: How do the brightness ratings compare?

A: The C503B-BCN-CU0W0452-030 provides 2850mcd versus the OVM4BTXV's 2260mcd at identical 20mA test current. This 26% brightness increase may be acceptable or require optical design adjustment depending on application requirements.

Q: Is the wavelength difference significant?

A: The shift from 465nm to 470nm represents a 5nm change within the blue spectrum. Both wavelengths are perceived as blue by human vision and are functionally equivalent for indication applications. Spectral matching requirements for specific optical systems should be evaluated independently.

Q: What is the viewing angle impact?

A: The substitute provides a 30° viewing angle compared to the original 18°. This wider angle increases visibility from off-axis positions, which is generally beneficial for indication LEDs but may require optical design review if narrow-angle performance is specifically required.

Q: Are regulatory certifications maintained?

A: Yes. Both components carry identical regulatory classifications: RoHS Compliant, REACH Unaffected, and ECCN EAR99. No additional compliance documentation is required for the substitution.
