MV8315 Yellow LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV8315 is a yellow LED indicator in T-1 3/4 (5mm) through-hole package manufactured by onsemi. This discrete 2.1V radial LED is designed for indication applications with a 2400mcd brightness rating and 12° viewing angle. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility across forward voltage, current rating, lens configuration, and mechanical dimensions to ensure direct circuit board replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MV8315 is based on the following critical parameters:

Electrical Compatibility: Forward voltage (Vf) must fall within 2.0V to 2.2V range to maintain circuit compatibility with existing current-limiting resistor designs. Test current remains constant at 20mA across all substitutes.

Optical Compatibility: Color (yellow) and lens transparency (clear) are mandatory. Wavelength peak must remain in the 583nm to 591nm range, consistent with yellow LED specifications.

Mechanical Compatibility: Lens size must be 5mm T-1 3/4 package. Through-hole radial mounting is required. Height variation must not exceed ±0.1mm from the 8.89mm maximum specification to ensure PCB clearance and component density compatibility.

Package Compliance: All substitutes must use radial through-hole configuration. Moisture sensitivity level of 1 (unlimited) is maintained across all alternatives.

Substitute parts are grouped into two categories: direct parametric equivalents (identical electrical and mechanical specifications) and functional substitutes (compatible within allowable parameter tolerances).

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent (Preferred):

MV8315A4R0 (Everlight Electronics Co Ltd) is the primary substitute. It maintains identical electrical specifications (2.1V Vf, 2400mcd, 12° viewing angle, 590nm wavelength) and mechanical dimensions (8.89mm height, 5mm T-1 3/4 package). The part is active in production with ROHS3 compliance, eliminating obsolescence risk while preserving circuit performance without modification.

Functional Substitutes (Compatible with Parameter Tolerance):

SLI-570YT3F and SLI-570Y2T3F (Rohm Semiconductor) are compatible substitutes. Both maintain 2.1V forward voltage and 590nm/591nm wavelength specifications. Increased brightness (5200mcd vs 2400mcd) and wider viewing angle (20° vs 12°) are acceptable for indication applications where higher visibility is beneficial. Height variation (8.85mm vs 8.89mm) is within mechanical tolerance. Both parts are active with ROHS3 compliance.

WP7113SYCK/J3 (Kingbright) is compatible with forward voltage tolerance (2.0V vs 2.1V nominal). Brightness increase (6000mcd) and wider viewing angle (20°) are acceptable for indication duty. Height (8.60mm) is within acceptable mechanical range. Part is active with ROHS3 compliance.

Limited Compatibility:

5219466F (Dialight) operates at 2.2V forward voltage, which is at the upper tolerance limit. Significantly reduced brightness (140mcd vs 2400mcd) makes this suitable only for applications where lower intensity is required. Use only when brightness reduction is intentional.

OVLGY0C9B9 (TT Electronics/Optek Technology) operates at 2.0V forward voltage and provides significantly higher brightness (14000mcd). Narrower viewing angle (8° vs 12°) concentrates light output. Use only when higher brightness and narrower beam are required.

Compliance Status:

All active substitute parts carry ROHS3 compliance certification. The obsolete MV8315 does not specify RoHS status. For new designs or production requiring RoHS compliance, select from active parts with ROHS3 designation.

Frequently Asked Questions (FAQ)

Q: Can MV8315A4R0 be used as a direct replacement for MV8315?

A: Yes. MV8315A4R0 is a parametric equivalent with identical forward voltage (2.1V), brightness (2400mcd), viewing angle (12°), wavelength (590nm), and mechanical dimensions (8.89mm height, 5mm T-1 3/4 package). No circuit modification is required.

Q: What is the difference between SLI-570YT3F and SLI-570Y2T3F?

A: Both parts are electrically and mechanically identical. They share the same forward voltage (2.1V), brightness (5200mcd), viewing angle (20°), wavelength (591nm), and height (8.85mm). The designation difference reflects internal Rohm Semiconductor product line variations. Either part is suitable for substitution.

Q: Will using a higher brightness LED (such as WP7113SYCK/J3 at 6000mcd) damage my circuit?

A: No. Higher brightness does not damage the circuit if forward voltage remains compatible (2.0V vs 2.1V nominal). The brightness difference is determined by LED die efficiency, not by increased current draw. Test current remains 20mA across all parts. Verify that your circuit's current-limiting resistor is sized for the substitute part's forward voltage to maintain proper operation.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed carry ROHS3 compliance certification. The original MV8315 (obsolete) does not specify RoHS status. For applications requiring RoHS compliance documentation, use only active parts with ROHS3 designation.

Q: Can I use 5219466F as a substitute if brightness is not critical?

A: 5219466F is compatible within electrical parameters (2.2V forward voltage is within tolerance) but provides significantly reduced brightness (140mcd vs 2400mcd). Use this part only if your application specifically requires lower intensity indication. Verify that the reduced brightness meets your visibility requirements before implementation.

Q: What is the viewing angle impact when substituting parts?

A: Viewing angle determines the cone of light emission. The MV8315 has a 12° viewing angle. Substitutes with wider angles (20° or 24°) distribute light over a broader area, improving visibility from off-axis positions. Substitutes with narrower angles (8°) concentrate light, requiring more precise alignment. Select based on your application's viewing geometry requirements.

Q: Are there any height restrictions I should consider?

A: All substitute parts have heights within 8.60mm to 8.90mm range, compared to MV8315's 8.89mm maximum. This ±0.3mm variation is within standard PCB component clearance tolerances and does not affect mounting or circuit board density. No mechanical redesign is required.

Q: What forward voltage tolerance should I apply when selecting a substitute?

A: The MV8315 operates at 2.1V typical. Acceptable substitutes fall within 2.0V to 2.2V range. This tolerance accommodates manufacturing variation and ensures compatibility with existing current-limiting resistor designs. Verify your circuit's resistor value is appropriate for the substitute part's forward voltage specification.
