LED Circuit Board Indicator MV54164 Equivalent & Substitute Parts

Part Overview

The Everlight Electronics MV54164 is a LED Circuit Board Indicator (CBI) featuring a 10-segment bar configuration in green with a vertical DIP mounting orientation. This component is designed for through-hole PCB assembly applications requiring visual status indication across multiple segments. The MV54164 is classified as obsolete, making identification of compatible substitute parts essential for ongoing production support and design continuity. The part operates at 2.2V with a 30mA current rating and delivers 1.8mcd luminous intensity through a rectangular flat-top lens measuring 5.08mm x 1.78mm.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV54164 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Configuration: Bar - 10 Wide, DIP (identical segment count and arrangement)
• Color: Green (x 10) (identical color specification)
• Voltage Rating: 2.2V (identical operating voltage)
• Mounting Type: Through Hole (identical PCB assembly method)
• Lens Style: Rectangle with Flat Top (identical optical geometry classification)
• Lens Size: 5.08mm x 1.78mm (mechanical fit requirement; tolerance of ±0.04mm acceptable)

Secondary Compatibility Parameters:

• Wavelength - Peak: 562nm to 565nm range (green spectrum consistency)
• Current Rating: 25mA to 30mA (acceptable operating range for indicator applications)
• Millicandela Rating: 1.8mcd to 8mcd (brightness variation acceptable for visual indication)
• RoHS Status: ROHS3 Compliant (regulatory requirement match)
• MSL Rating: 1 (Unlimited) (moisture sensitivity compatibility)

The substitute part SSA-LXB10GW-GF/LP from Lumex Opto/Components Inc. meets all primary and secondary compatibility criteria, establishing it as a valid electrical and mechanical equivalent for the obsolete MV54164.

Parameter Comparison

Engineering Selection Recommendations

The SSA-LXB10GW-GF/LP from Lumex Opto/Components Inc. is qualified as a direct substitute for the obsolete MV54164 based on the following engineering factors:

Regulatory Compliance: Both components maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with current manufacturing and environmental standards.

Electrical Equivalence: The 2.2V voltage rating and 25mA current specification of the SSA-LXB10GW-GF/LP operate within the acceptable range for the MV54164 application. The 5mA current reduction represents a 16.7% decrease, which is acceptable for indicator-class LED applications where brightness variation is tolerable.

Optical Compatibility: The wavelength shift from 562nm to 565nm remains within the green spectrum and is imperceptible to human vision. The increased millicandela rating (8mcd versus 1.8mcd) provides enhanced brightness margin without requiring circuit redesign.

Mechanical Fit: The lens dimensions of 5.08mm x 1.74mm versus 5.08mm x 1.78mm represent a 0.04mm height reduction, which falls within standard PCB assembly tolerances and does not compromise mechanical fit or visual alignment.

Product Availability: The SSA-LXB10GW-GF/LP maintains active product status with 2932 units in stock, providing supply continuity for the obsolete MV54164.

Frequently Asked Questions (FAQ)

Q: Can the SSA-LXB10GW-GF/LP be used as a direct replacement for the MV54164 without PCB modifications?

A: Yes. Both components share identical voltage ratings (2.2V), mounting type (through-hole), and configuration (10-segment bar DIP). The lens dimension difference of 0.04mm is within standard PCB assembly tolerances and does not require layout changes.

Q: What is the impact of the 5mA current reduction from 30mA to 25mA?

A: The SSA-LXB10GW-GF/LP operates at 25mA versus the MV54164's 30mA specification. This 16.7% reduction is acceptable for indicator applications. Circuit current-limiting resistors should be recalculated based on the 2.2V forward voltage and desired brightness level. The higher millicandela rating (8mcd) of the substitute compensates for the lower current.

Q: Are there wavelength differences between the two parts?

A: The MV54164 operates at 562nm peak wavelength while the SSA-LXB10GW-GF/LP operates at 565nm. Both wavelengths fall within the green spectrum and produce visually identical color perception. The 3nm difference is not discernible to human vision.

Q: What is the difference between the lens types listed for each part?

A: The MV54164 features a standard rectangular flat-top lens, while the SSA-LXB10GW-GF/LP specifies a diffused white lens with a 160° viewing angle. The diffused lens provides wider viewing angle distribution and reduced glare compared to the standard lens, which is beneficial for indicator applications.

Q: Are both components RoHS compliant?

A: Yes. Both the MV54164 and SSA-LXB10GW-GF/LP are ROHS3 compliant and carry identical MSL ratings of 1 (Unlimited), ensuring compatibility with current manufacturing standards and storage requirements.

Q: What is the packaging difference between these parts?

A: The MV54164 is supplied in standard packaging, while the SSA-LXB10GW-GF/LP is supplied in tube packaging. Tube packaging is standard for through-hole components and does not affect electrical or mechanical compatibility.
