MPC3SRDL LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPC3SRDL is an industrial metal panel-mount LED indicator manufactured by Bivar Inc., designed for applications requiring a red diffused lens with low-power operation. This component features a 3mm T-1 lens form factor with a round domed top, suitable for standard 6.10mm (0.24") panel cutouts. The MPC3SRDL is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the panel cutout dimensions and electrical operating parameters while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC3SRDL is determined by strict adherence to the following mechanical and electrical compatibility criteria:

Mechanical Compatibility Requirements:

• Panel cutout shape must be round
• Panel cutout dimensions must be 0.24" (6.10mm)
• Lens size must be 3mm, T-1 form factor
• Lens style must be round with domed top

Electrical Compatibility Parameters:

• Lamp color must be red
• Lens transparency must be diffused
• Operating voltage range must accommodate the circuit design
• Operating current must be within circuit current-limiting capability

Regulatory & Compliance Alignment:

• ECCN classification: EAR99
• HTSUS code: 8541.41.0000
• Moisture Sensitivity Level: 1 (Unlimited)

The MPC3RD qualifies as a substitute part based on matching all mechanical compatibility requirements and maintaining red diffused lens characteristics. Electrical parameters differ within acceptable ranges for panel indicator applications, and the part is classified as active with current manufacturing status and full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The MPC3RD is a valid substitute for the obsolete MPC3SRDL based on identical mechanical compatibility and matching core functional characteristics (red diffused LED indicator in 3mm T-1 form factor with 6.10mm panel cutout).

Electrical Parameter Considerations:

The MPC3RD operates at 2.1V typical forward voltage compared to 2V for the MPC3SRDL. This 0.1V difference is within typical circuit tolerance ranges for LED indicator applications. The MPC3RD supports a maximum current of 20mA versus 7mA for the original part. Circuit current-limiting resistors must be sized to operate the MPC3RD within appropriate current levels for the specific application.

Optical Parameter Differences:

The MPC3RD produces 2mcd compared to 8mcd for the MPC3SRDL, representing a reduction in brightness. The wavelength shift from 645nm to 700nm results in a deeper red color appearance. The viewing angle narrows from 35° to 20°. These optical differences require evaluation against specific application visibility and color requirements.

Compliance & Availability:

The MPC3RD is classified as active with current manufacturing status and holds ROHS3 compliance certification. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, and both maintain MSL 1 (Unlimited) moisture sensitivity ratings. The MPC3RD is available in tray packaging with 1138 pieces in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the MPC3RD be used as a direct replacement for the MPC3SRDL without circuit modifications?

A: The MPC3RD is mechanically compatible and will fit the same 6.10mm panel cutout. However, the electrical characteristics differ. The forward voltage is 0.1V higher (2.1V vs. 2V), and the maximum current rating is higher (20mA vs. 7mA). Existing current-limiting resistors should be evaluated to ensure proper operation. No circuit modifications are typically required for standard indicator applications, but verification of brightness and color appearance is recommended.

Q: What is the significance of the wavelength difference between 645nm and 700nm?

A: The MPC3SRDL operates at 645nm (standard red), while the MPC3RD operates at 700nm (deep red). This 55nm shift results in a visually deeper, more saturated red color. In applications where color consistency with other indicators is critical, this difference should be considered. Both wavelengths fall within the red spectrum and are suitable for standard indicator applications.

Q: Why is the brightness rating lower for the MPC3RD (2mcd vs. 8mcd)?

A: The MPC3RD is rated at 2mcd while the MPC3SRDL is rated at 8mcd. This represents a reduction in peak luminous intensity. For applications requiring high visibility or long-distance viewing, this difference is significant. For standard panel indicator applications with close viewing distances, the 2mcd rating is typically adequate. Application-specific visibility requirements should be evaluated.

Q: What does the narrower viewing angle of the MPC3RD (20° vs. 35°) mean for my application?

A: The MPC3SRDL has a 35° viewing angle, while the MPC3RD has a 20° viewing angle. A narrower viewing angle means the LED appears bright when viewed directly but dims more rapidly when viewed from the side. For applications where the indicator is viewed from multiple angles or positions, the narrower angle may be a limitation. For front-facing panel indicators viewed primarily from one direction, this difference is typically not significant.

Q: Are there any packaging differences between the MPC3SRDL and MPC3RD?

A: The MPC3SRDL packaging information is not specified in the available data. The MPC3RD is supplied in tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to the MPC3RD?

A: The MPC3RD is ROHS3 compliant and REACH unaffected. Both the MPC3SRDL and MPC3RD share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring consistent export and tariff treatment.

Q: Is the MPC3RD suitable for applications requiring unlimited moisture exposure?

A: Both the MPC3SRDL and MPC3RD are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations. Both parts are suitable for applications without moisture-related handling restrictions.
