MV5433 Equivalent & Substitute Parts

Part Overview

The MV5433 is a bi-color LED indicator (green/yellow) manufactured by onsemi, featuring a common cathode configuration with diffused lens in a T-1 3/4 (5mm) through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

The MV5433 provides dual-color indication capability with 6mcd brightness in both green and yellow channels, suitable for status indication applications requiring discrete LED solutions with radial lead configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV5433 is determined by the following critical parameters:

• Configuration Match: Common cathode, bi-color (green/yellow) LED
• Package Compatibility: T-1 3/4 (5mm) through-hole radial package with 3 leads
• Electrical Compatibility: Forward voltage within acceptable operating range (±0.2V tolerance typical for LED applications); test current 20mA for both channels
• Optical Characteristics: Diffused lens, round domed top; wavelength range within visible spectrum for green (560-570nm) and yellow (580-595nm)
• Mechanical Fit: Height and form factor suitable for through-hole PCB mounting
• Regulatory Compliance: REACH and RoHS status for end-use application requirements

The WP59GYW from Kingbright meets these substitution criteria as an active product with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The WP59GYW from Kingbright is a qualified substitute for the obsolete MV5433 based on the following engineering criteria:

Electrical Compatibility: Forward voltage differences (0.1V green, 0.2V yellow) are within standard LED tolerance ranges and do not require circuit redesign for typical current-limiting resistor applications.

Package and Mechanical Fit: Both components use identical T-1 3/4 through-hole radial packages with 3-lead configuration. The 1.27mm height difference (WP59GYW: 11.35mm vs. MV5433: 10.08mm) must be verified against PCB clearance constraints in the target application.

Optical Performance: Peak wavelengths remain within acceptable ranges for green and yellow indication. The WP59GYW provides higher brightness (50mcd green, 40mcd yellow vs. 6mcd for both channels on MV5433), which may require circuit adjustment if the original design relied on the lower brightness specification for current limiting or visual balance.

Product Status and Compliance: The WP59GYW is an active product with ROHS3 compliance certification, ensuring long-term availability and regulatory support compared to the obsolete MV5433.

Viewing Angle Consideration: The MV5433 offers a 100° viewing angle versus 60° for the WP59GYW. Applications requiring wide-angle indication should evaluate whether the narrower viewing angle of the substitute is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the WP59GYW directly replace the MV5433 without circuit modifications?

A: The WP59GYW is electrically compatible with the MV5433 in standard current-limiting resistor circuits. However, the higher brightness of the WP59GYW (50mcd vs. 6mcd green; 40mcd vs. 6mcd yellow) may require resistor adjustment if the original design was optimized for the lower brightness specification. Forward voltage differences are within acceptable tolerance and do not require redesign.

Q: What is the impact of the 1.27mm height difference between these components?

A: The WP59GYW is 1.27mm taller than the MV5433 (11.35mm vs. 10.08mm). Verify that the target PCB layout and enclosure design provide adequate clearance above the component. This difference is typically not problematic for standard through-hole applications but must be confirmed for space-constrained designs.

Q: Does the narrower viewing angle of the WP59GYW affect substitution suitability?

A: The WP59GYW has a 60° viewing angle compared to the MV5433's 100° angle. For applications where wide-angle visibility is critical, the narrower viewing angle may impact performance. Evaluate the specific application requirements for indicator visibility from multiple angles.

Q: Are there regulatory or compliance differences between these components?

A: The WP59GYW carries ROHS3 compliance certification, while the MV5433 status is not specified. Both components are REACH Unaffected. For applications requiring RoHS compliance, the WP59GYW provides documented compliance assurance.

Q: What is the availability status of each component?

A: The MV5433 is classified as obsolete and subject to limited availability. The WP59GYW is an active product with documented inventory (18,058 pcs), ensuring reliable long-term procurement and supply chain continuity.

Q: Are the wavelength specifications compatible between these components?

A: Peak wavelengths are compatible within visible spectrum tolerances. Green wavelength is identical (565nm). Yellow wavelength differs by 5nm (MV5433: 585nm vs. WP59GYW: 590nm), which is imperceptible to human vision and does not affect functional compatibility for indication applications.
