LED Panel Indicator MPC3YD5V Equivalent & Substitute Parts

Part Overview

The MPC3YD5V is a 3mm yellow diffused LED panel indicator manufactured by Bivar Inc., rated for 5V operation with a 20mcd brightness output and 35° viewing angle. This component is designed for panel-mount applications with a standard 0.24" (6.10mm) round cutout.

The MPC3YD5V has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure continued availability for production, maintenance, and repair applications.

Engineering Selection Recommendations

Mechanical Fit: The SSI-LXR3612YD provides direct mechanical compatibility with the MPC3YD5V. Both components feature identical 3mm T-1 lens size, round domed top lens style, and 0.24" (6.10mm) panel cutout dimensions. Panel mounting is interchangeable without modification.

Optical Performance: Both parts deliver yellow diffused light suitable for panel indicator applications. The SSI-LXR3612YD provides 30mcd brightness compared to the MPC3YD5V's 20mcd, representing a 50% increase in light output. The viewing angle expands from 35° to 60°, providing wider visibility. Peak wavelengths differ by 5nm (590nm vs. 585nm), remaining within the yellow spectrum with no perceptible color difference.

Electrical Considerations: The primary difference is voltage rating. The MPC3YD5V operates at 5V, while the SSI-LXR3612YD has a forward voltage (Vf) of 2.1V typical with maximum current of 30mA. Circuit redesign or current-limiting resistor adjustment may be required depending on the original circuit topology. This substitution is not suitable for direct pin-for-pin replacement without electrical circuit evaluation.

Product Status & Availability: The MPC3YD5V is obsolete with no ongoing production. The SSI-LXR3612YD is in active production status with 3362 units in stock, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The SSI-LXR3612YD carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the SSI-LXR3612YD be used as a direct replacement for the MPC3YD5V without circuit modification?

A: No. While mechanical fit is identical, the voltage ratings differ significantly (5V vs. 2.1V). The substitute requires circuit evaluation and likely resistor adjustment to operate correctly. Direct substitution without electrical analysis will result in component failure or malfunction.

Q: What is the impact of the 10mcd brightness difference between the two parts?

A: The SSI-LXR3612YD provides 30mcd versus the MPC3YD5V's 20mcd. This 50% increase in brightness is generally acceptable for panel indicator applications and often improves visibility. Applications with specific brightness requirements should evaluate whether increased output affects design intent.

Q: Does the wider 60° viewing angle of the SSI-LXR3612YD affect compatibility?

A: The wider viewing angle is a functional improvement. The substitute provides visibility across a broader angular range compared to the original 35° specification. This is compatible with and generally beneficial for panel-mounted indicator applications.

Q: Are there any supply chain advantages to using the SSI-LXR3612YD?

A: Yes. The MPC3YD5V is obsolete with no ongoing production. The SSI-LXR3612YD is in active production with 3362 units currently in stock, ensuring reliable long-term availability and reducing supply chain risk.

Q: What are the packaging differences between these parts?

A: The MPC3YD5V packaging is listed as "-" (not specified). The SSI-LXR3612YD is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are both parts compliant with current environmental regulations?

A: The SSI-LXR3612YD carries ROHS3 compliance and REACH unaffected status. The MPC3YD5V compliance status is not specified in available data. For applications requiring documented environmental compliance, the SSI-LXR3612YD provides verified certification.

Q: What is the wavelength difference between 590nm and 585nm?

A: Both wavelengths fall within the yellow spectrum. The 5nm difference is not perceptible to human vision and produces visually equivalent yellow color. Both parts are suitable for applications requiring yellow indication.
