MV6463T LED Green/Yellow Diffused T-1 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV6463T is a dual-color LED indicator (green/yellow) manufactured by onsemi in a T-1 through-hole package with diffused lens. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The part provides green indication at 2.1V forward voltage and yellow indication at 2V forward voltage, with test currents of 20mA for both colors. Due to its obsolete status, sourcing alternatives from active product lines is necessary for new designs and component replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MV6463T is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Dual-color configuration (green and yellow)
• Diffused lens type with round domed top geometry
• 3mm T-1 package form factor
• Through-hole radial mounting
• Forward voltage compatibility: green channel 2.0V–2.2V range, yellow channel 1.9V–2.1V range
• Test current: 20mA for both colors
• Viewing angle: 60°–70° acceptable range
• Peak wavelength: green 565nm±5nm, yellow 585nm–590nm range

The WP937GYW from Kingbright meets these substitution criteria as an active product with compatible electrical characteristics, identical package geometry, and equivalent optical properties within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

The WP937GYW is the qualified substitute for the obsolete MV6463T based on the following factors:

Product Status: The WP937GYW maintains active product status with Kingbright, ensuring long-term availability and supply chain continuity compared to the obsolete MV6463T.

Compliance & Certifications: Both parts share identical REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited) classification, confirming equivalent regulatory compliance and environmental handling requirements.

Electrical Compatibility: Forward voltage specifications differ by 0.1V on each color channel, which is within standard circuit design tolerances for LED indicator applications. Test current remains constant at 20mA for both colors.

Mechanical Compatibility: Identical T-1 package geometry, radial through-hole mounting, and diffused lens configuration ensure direct PCB footprint compatibility. Height variance of 0.6mm is negligible for through-hole applications.

Optical Characteristics: Peak wavelength alignment for green (565nm exact match) and yellow (590nm vs. 585nm, 5nm variance) maintains color consistency. Viewing angle reduction from 70° to 60° is acceptable for standard indicator applications. Brightness differences (green channel higher in WP937GYW, yellow channel higher in MV6463T) should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the WP937GYW directly replace the MV6463T without circuit modification?

A: Yes. The WP937GYW is electrically and mechanically compatible with the MV6463T. Forward voltage differences of 0.1V per color channel fall within standard LED circuit design tolerances. No circuit redesign is required for direct substitution in existing applications.

Q: What is the significance of the 0.1V forward voltage difference?

A: Forward voltage variance of 0.1V is typical across LED product lines and does not affect circuit functionality in standard indicator applications. Current-limiting resistor values remain valid across this voltage range.

Q: Does the brightness difference between the two parts affect substitution?

A: Brightness differences exist: WP937GYW provides higher green brightness (14mcd vs. 4.5mcd), while MV6463T provides higher yellow brightness (15mcd vs. 8mcd). Application requirements determine acceptability. If specific brightness levels are critical, circuit design adjustments may be necessary.

Q: Is the 10° viewing angle reduction from 70° to 60° significant?

A: For standard indicator applications, a 60° viewing angle is sufficient. The reduction is significant only in applications requiring wide-angle visibility. Verify application requirements before substitution.

Q: Are there any packaging or handling differences?

A: Both parts share identical Moisture Sensitivity Level 1 (Unlimited) classification and REACH Unaffected status. Handling and storage requirements are equivalent. WP937GYW is supplied in bulk packaging versus the MV6463T's original packaging.

Q: What is the height difference impact on PCB layout?

A: The WP937GYW is 0.6mm shorter (5.60mm vs. 6.20mm). This difference is negligible for through-hole applications and does not affect PCB clearance or mechanical fit in standard designs.

Q: Can the WP937GYW be used in new designs?

A: Yes. The WP937GYW is an active product with confirmed long-term availability, making it the preferred choice for new designs requiring dual-color green/yellow T-1 LED indicators with diffused lenses.
