MV5377C LED Yellow Diffused T-1 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV5377C is a yellow diffused LED in T-1 (3mm) through-hole package manufactured by onsemi. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity. The MV5377C serves as a yellow LED indicator in discrete applications requiring 2.1V forward voltage operation at 20mA test current with 7mcd luminous intensity and 140° viewing angle.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV5377C is determined by the following critical parameters:

• Color: Yellow (primary functional requirement)
• Lens Transparency: Diffused (optical characteristic)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: Radial (form factor)
• Supplier Device Package: T-1 (3mm) (physical footprint)
• Voltage - Forward (Vf): 2.1V nominal (electrical compatibility)
• Current - Test: 20mA (operational specification)

The SSL-LX306F4SYD from Lumex Opto/Components Inc. qualifies as a direct substitute based on matching color (yellow), lens transparency (diffused), mounting type (through hole), package configuration (radial T-1), forward voltage (2.1V), and test current (20mA). The SSL-LX306F4SOD (orange variant) is listed as a related part but differs in color specification and is not a direct functional equivalent for yellow LED applications.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX306F4SYD represents the primary substitute for the obsolete MV5377C. Both components share identical electrical specifications (2.1V forward voltage, 20mA test current) and functional characteristics (yellow color, diffused lens, through-hole radial package). The SSL-LX306F4SYD carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Differences in millicandela rating (100mcd vs. 7mcd) and viewing angle (60° vs. 140°) reflect design improvements in the Lumex component. The increased luminous intensity and narrower viewing angle may require circuit-level evaluation depending on application requirements. Physical height variation (7.65mm vs. 5.20mm) must be assessed for PCB layout and mechanical clearance compatibility.

The SSL-LX306F4SOD (orange variant) is not recommended as a substitute for yellow LED applications due to color mismatch, despite sharing package and mounting characteristics.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX306F4SYD directly replace the MV5377C without circuit modification?

A: Electrical compatibility is confirmed through matching forward voltage (2.1V) and test current (20mA) specifications. Physical compatibility requires verification of PCB hole spacing and height clearance, as the SSL-LX306F4SYD maximum height is 7.65mm compared to 5.20mm for the MV5377C.

Q: What is the impact of the higher millicandela rating (100mcd vs. 7mcd) on circuit design?

A: The SSL-LX306F4SYD provides significantly higher luminous intensity. Applications requiring the original 7mcd output may need series resistor adjustment to maintain equivalent brightness levels and prevent LED over-current conditions.

Q: Are there mechanical compatibility concerns between these components?

A: Both components use T-1 (3mm) through-hole radial packages with round domed-top lenses. The primary mechanical difference is maximum height: MV5377C at 5.20mm and SSL-LX306F4SYD at 7.65mm. Verify PCB layout clearance and component spacing before substitution.

Q: Why is the SSL-LX306F4SOD listed if it cannot replace the MV5377C?

A: The SSL-LX306F4SOD is included as a related part within the Lumex SSL-LX306 series. It shares identical package, mounting, and electrical test specifications but differs in color (orange vs. yellow), making it unsuitable for yellow LED indication applications.

Q: What compliance advantages does the SSL-LX306F4SYD offer?

A: The SSL-LX306F4SYD carries ROHS3 compliance and active product status, ensuring regulatory alignment and production continuity. The MV5377C is classified as obsolete with no specified RoHS status.
