MV53173 LED Indicator Bar - Equivalent & Substitute Parts

Part Overview

The MV53173 is a yellow LED indicator bar manufactured by onsemi, designed for circuit board applications. This component features a single SIP configuration with a 12.70mm x 6.35mm rectangular flat-top lens, rated for 2V operation at 20mA. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV53173 is determined by the following critical parameters:

• Color and Wavelength: Yellow (585nm peak wavelength) - must match for visual consistency
• Lens Geometry: 12.70mm x 6.35mm rectangular flat-top configuration - must match for mechanical fit
• Mounting Type: Through-hole - must match for PCB compatibility
• Electrical Compatibility: Voltage and current ratings must support the application circuit without modification

Two substitute parts meet these criteria:

LTL-53173Y (Lite-On Inc.): Maintains identical lens size (12.70mm x 6.35mm), matching wavelength (585nm), and through-hole mounting. Configuration changes from SIP to DIP with increased current rating (80mA at 2.1V).

DE2YD (Kingbright): Maintains yellow color (590nm wavelength) and through-hole mounting with increased lens size (14.00mm x 7.50mm) and current rating (30mA at 2.1V). Configuration changes from SIP to DIP.

Parameter Comparison

Engineering Selection Recommendations

LTL-53173Y (Lite-On Inc.) is the primary substitute for direct replacement applications. This part maintains identical lens dimensions (12.70mm x 6.35mm) and peak wavelength (585nm), ensuring mechanical and optical compatibility. The product is active with RoHS3 compliance. The increased current rating (80mA versus 20mA) and voltage (2.1V versus 2V) require circuit verification to confirm the application can accommodate these parameters without modification.

DE2YD (Kingbright) serves as an alternative where increased brightness (26mcd versus 4.5mcd) is acceptable or beneficial. This part features a larger lens (14.00mm x 7.50mm) and diffused, tinted lens type, which may require PCB layout adjustment. The wavelength shift (590nm versus 585nm) remains within the yellow spectrum. Product is active with RoHS3 compliance. The 30mA current rating and 2.1V voltage require circuit compatibility verification.

Both substitutes are active products with unlimited moisture sensitivity rating and REACH unaffected status, providing long-term supply continuity compared to the obsolete MV53173.

Frequently Asked Questions (FAQ)

Q: Can LTL-53173Y replace MV53173 without PCB modifications?

A: LTL-53173Y maintains identical lens size and mounting footprint. However, the configuration change from SIP to DIP and increased electrical ratings (80mA at 2.1V) require circuit verification. PCB trace routing may differ between SIP and DIP configurations.

Q: What is the primary difference between LTL-53173Y and DE2YD?

A: LTL-53173Y preserves the original lens size (12.70mm x 6.35mm) with matching wavelength (585nm), while DE2YD features a larger lens (14.00mm x 7.50mm) with higher brightness (26mcd) and slightly longer wavelength (590nm). Lens size difference necessitates PCB layout evaluation.

Q: Are both substitutes RoHS compliant?

A: Yes. LTL-53173Y and DE2YD are both RoHS3 compliant, meeting current environmental regulations. The original MV53173 does not specify RoHS status.

Q: How do the electrical ratings affect substitution?

A: MV53173 operates at 2V/20mA. LTL-53173Y requires 2.1V/80mA, and DE2YD requires 2.1V/30mA. Applications must verify that the circuit can supply these increased current levels without exceeding component or PCB thermal limits.

Q: What is the impact of lens type differences?

A: MV53173 and LTL-53173Y have unspecified lens types (standard). DE2YD features a diffused, tinted lens, which affects light distribution and perceived brightness. This may impact visual indication characteristics in the application.

Q: Are all three parts through-hole mounted?

A: Yes. MV53173, LTL-53173Y, and DE2YD are all through-hole mounted components, maintaining consistent PCB assembly compatibility.
