MPC5PGC Equivalent & Substitute Parts

Part Overview

The MPC5PGC is a panel-mounted LED indicator manufactured by Bivar Inc., featuring a 5mm round domed lens with clear transparency and green lamp color. This component is rated at 555nm peak wavelength with 10 millicandela luminous intensity and a 35° viewing angle. The part carries an Obsolete product status, requiring evaluation of active alternative components for new designs or inventory replenishment. Substitutes must maintain mechanical compatibility with the 0.32" (8.13mm) round panel cutout and preserve critical electrical performance within specified voltage and current ratings.

Substitute Part Grouping Explanation

The MPC5GD serves as a functional equivalent to the MPC5PGC based on the following substitution criteria:

Mechanical Compatibility: Both components feature identical panel cutout configuration (0.32" / 8.13mm round), 5mm T-1 3/4 lens form factor, and round domed lens style, enabling direct mechanical interchange in existing panel designs without hardware modification.

Electrical Compatibility: The voltage ratings are within acceptable tolerances (2.2V primary vs. 2.1V substitute), and both components are rated for 30mA maximum current. The forward voltage differential of 0.1V falls within normal LED manufacturing variations and does not compromise circuit operation when proper current-limiting resistors are applied.

Optical Performance Variance: The MPC5GD exhibits a 25mcd luminous intensity compared to the MPC5PGC's 10mcd, representing a brightness increase suitable for equivalent visual indication. The wavelength shift from 555nm to 568nm (±13nm) remains within the green spectral range and maintains consistent color perception. The expanded viewing angle (45° vs. 35°) improves visibility without degrading optical performance.

Lens Transparency Trade-off: The MPC5GD employs a diffused lens rather than clear transparency. This modification distributes light more uniformly across the viewing angle, creating a broader illumination pattern. The substitution is valid where diffused appearance is acceptable or preferred for distributed visibility in panel-mounted applications.

Product Status Advantage: The MPC5GD maintains Active product status with ROHS3 compliance and REACH Unaffected designation, supporting continued supply chain availability and regulatory conformance for new designs.

Parameter Comparison

Engineering Selection Recommendations

The MPC5GD is electrically and mechanically suitable for replacing the MPC5PGC in panel-mounted applications. The Obsolete designation of the MPC5PGC necessitates transition to the MPC5GD for production designs requiring sustained component availability. The MPC5GD's Active product status ensures continued supply chain support.

Compliance certifications align favorably: both components carry EAR99 ECCN classification and identical Moisture Sensitivity Level ratings. The MPC5GD adds ROHS3 Compliant and REACH Unaffected designations, confirming adherence to modern environmental and regulatory requirements without additional design modifications.

The brightness increase (10mcd to 25mcd) and expanded viewing angle (35° to 45°) provide optical performance benefits when substituting the MPC5GD. The lens transparency change from clear to diffused affects visual appearance; applications sensitive to lens clarity require assessment of diffused optical characteristics against functional requirements.

Frequently Asked Questions (FAQ)

Q: Can MPC5GD directly replace MPC5PGC without circuit redesign? A: Yes. The 0.1V forward voltage difference (2.2V to 2.1V) remains within LED circuit tolerances when proper current-limiting resistors are specified. No circuit modifications are necessary for the electrical substitution.

Q: Are mechanical panel modifications required for MPC5GD installation? A: No. Both components share identical panel cutout dimensions (0.32" / 8.13mm round) and lens form factor (5mm, T-1 3/4), enabling direct mechanical interchange without panel rework.

Q: How does the diffused lens affect visual performance compared to the clear lens? A: The diffused lens distributes light more uniformly across the 45° viewing angle, creating a broader illumination pattern. The clear lens concentrates light more directionally within the 35° cone. Selection depends on whether distributed or concentrated light appearance is required for the application.

Q: Does the increased brightness (25mcd vs. 10mcd) create compatibility concerns? A: No. Higher luminous intensity enhances visibility without adverse effects on circuit operation or optical stability. The brightness increase supports improved indicator visibility in applications where the MPC5PGC's 10mcd rating was marginal.

Q: Is the wavelength shift (555nm to 568nm) significant for color matching? A: The 13nm wavelength difference remains within the green spectral range and maintains consistent green color perception to the human eye. Both components produce visually equivalent green indication in standard panel applications.

Q: What is the Moisture Sensitivity Level significance for panel-mounted applications? A: MSL 1 (Unlimited) indicates the component tolerates indefinite exposure to ambient moisture without reflow requirements, suitable for standard panel-mount assembly without special moisture-control procedures during manufacturing and storage.

Q: Why is the MPC5GD recommended despite the MPC5PGC availability? A: The MPC5PGC carries Obsolete product status, limiting long-term supply availability. The MPC5GD's Active status, ROHS3 compliance, and REACH Unaffected designation ensure continued supply chain support and regulatory conformance for ongoing production.
