LED CBI 5MM YELLOW RA MV64538MP7 Equivalent & Substitute Parts

Part Overview

The MV64538MP7 is a Circuit Board Indicator (CBI) LED manufactured by Fairchild Semiconductor. This component is a single yellow LED with a 5mm round domed top lens, designed for through-hole right-angle mounting applications. The part operates at 2.1V with a 20mA rated current and delivers 18 millicandela brightness at a 65-degree viewing angle.

The MV64538MP7 maintains active product status with bulk packaging availability. Substitute parts are necessary when primary inventory is depleted, when alternative manufacturers are required for supply chain diversification, or when specific performance characteristics such as lens diffusion properties are required for application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV64538MP7 are qualified based on the following critical parameters that determine functional interchangeability:

Core Electrical Parameters:

• Voltage Rating: 2.1V
• Current Rating: 20mA
• Color: Yellow
• Configuration: Single LED

Mechanical Parameters:

• Lens Size: 5mm, T-1 3/4
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole, Right Angle
• Viewing Angle: 65°

Optical Parameters:

• Millicandela Rating: 18mcd to 20mcd range

Substitute parts must match all core electrical and mechanical parameters. Variations in lens type (diffused versus clear) and manufacturer do not affect functional substitution when all other parameters remain constant. Brightness ratings within the specified range maintain circuit performance requirements.

Parameter Comparison

Engineering Selection Recommendations

MV63538MP7 (Fairchild Semiconductor): This substitute maintains identical electrical and mechanical specifications to the MV64538MP7. Both parts are manufactured by Fairchild Semiconductor and carry active product status. The MV63538MP7 is suitable for direct substitution in applications where inventory of the primary part is unavailable. Both parts share equivalent moisture sensitivity levels and export classifications.

MV63539MP6 (onsemi): This substitute meets all core electrical and mechanical requirements with a brightness rating of 20mcd, which exceeds the 18mcd specification of the main part. The MV63539MP6 features a diffused, tinted lens type compared to the standard lens of the main part. This part carries obsolete product status and features superior moisture sensitivity (MSL 1 versus MSL 3). The onsemi part is suitable for substitution when supply from active manufacturers is exhausted and application requirements permit use of diffused lens optics.

Selection between active and obsolete parts should prioritize active product status for new designs and long-term supply chain stability. The onsemi MV63539MP6 is appropriate only for legacy system maintenance or when diffused lens characteristics are specifically required.

Frequently Asked Questions (FAQ)

Q: Can MV63538MP7 be used as a direct replacement for MV64538MP7?

A: Yes. Both parts share identical voltage ratings (2.1V), current ratings (20mA), lens size (5mm T-1 3/4), mounting type (through-hole right angle), and viewing angle (65°). Both are manufactured by Fairchild Semiconductor and maintain active product status. Substitution is electrically and mechanically compatible.

Q: What is the difference between MV64538MP7 and MV63539MP6?

A: The primary difference is the lens type. MV63539MP6 features a diffused, tinted lens, while MV64538MP7 uses a standard lens. Both parts operate at identical voltage (2.1V) and current (20mA) ratings. MV63539MP6 delivers 20mcd brightness compared to 18mcd for MV64538MP7. MV63539MP6 is manufactured by onsemi and carries obsolete product status, while MV64538MP7 is active.

Q: Is the onsemi MV63539MP6 suitable for new product designs?

A: No. The MV63539MP6 carries obsolete product status, making it unsuitable for new designs requiring long-term supply availability. Use active parts MV64538MP7 or MV63538MP7 for new applications.

Q: What does the diffused lens on MV63539MP6 affect?

A: The diffused, tinted lens affects light distribution and appearance. The 65-degree viewing angle remains constant. Diffused lenses scatter light over a wider area compared to clear lenses, which may alter visual perception in the application but does not change electrical performance.

Q: Are all three parts RoHS compliant?

A: MV64538MP7 and MV63538MP7 list RoHS status as not applicable. MV63539MP6 does not specify RoHS status in the provided data. Verify RoHS compliance requirements with the manufacturer for your specific application.

Q: What is the moisture sensitivity difference between these parts?

A: MV64538MP7 and MV63538MP7 both have MSL 3 (168 hours), requiring controlled storage conditions. MV63539MP6 has MSL 1 (unlimited), indicating superior moisture resistance and less stringent storage requirements.
