MPC5BWC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPC5BWC is a panel-mounted LED indicator manufactured by Bivar Inc., featuring a blue light-emitting element with a clear lens and 20° viewing angle. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. The MPC5BWC operates at 4V with a maximum current of 25mA and provides 25mcd luminous intensity at a peak wavelength of 430nm.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC5BWC is determined by strict compatibility across the following electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Voltage rating: 4V (must match)
• Maximum current: 25mA (must match)
• Peak wavelength: 430nm (must match for blue color specification)

Mechanical Compatibility Requirements:

• Panel cutout dimensions: 0.32" (8.13mm) round (must match for panel mounting)
• Lens size: 5mm, T-1 3/4 (must match for physical fit)
• Lens style: Round with domed top (must match for form factor)

Allowable Variations:

• Lens transparency (clear to diffused) is allowable based on application requirements
• Viewing angle may vary (20° to 45°) depending on visibility requirements
• Millicandela rating may vary (15mcd to 25mcd) based on brightness requirements
• Product status transition from obsolete to active is acceptable for procurement purposes

The MPC5BWD meets all mandatory compatibility criteria and serves as an active equivalent for the obsolete MPC5BWC.

Parameter Comparison

Engineering Selection Recommendations

The MPC5BWD is the active equivalent for the obsolete MPC5BWC within the MPC5 series. Selection of MPC5BWD is supported by the following factors:

Electrical Compatibility: Both parts operate at identical voltage (4V) and current (25mA) ratings with matching peak wavelength (430nm), ensuring direct electrical substitution without circuit modification.

Mechanical Compatibility: Identical panel cutout dimensions (0.32" / 8.13mm), lens size (5mm T-1 3/4), and lens style (round domed top) confirm direct mechanical fit in existing panel mount applications.

Regulatory Compliance: The MPC5BWD carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Operational Differences: The MPC5BWD features a diffused blue lens versus the clear colorless lens of the MPC5BWC, resulting in a 15mcd rating versus 25mcd and a 45° viewing angle versus 20°. These differences affect light distribution characteristics and should be evaluated against specific application visibility requirements.

Product Status: Transition from obsolete (MPC5BWC) to active (MPC5BWD) status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can MPC5BWD directly replace MPC5BWC in existing designs?

A: Yes. Both parts share identical electrical ratings (4V, 25mA), mechanical dimensions (0.32" panel cutout, 5mm lens), and wavelength (430nm). Direct substitution is electrically and mechanically compatible. The diffused lens of MPC5BWD versus the clear lens of MPC5BWC affects light distribution and brightness perception.

Q: What is the difference between the clear lens (MPC5BWC) and diffused lens (MPC5BWD)?

A: The MPC5BWC features a clear colorless lens providing focused light output at 25mcd with a 20° viewing angle. The MPC5BWD features a diffused blue lens providing dispersed light output at 15mcd with a 45° viewing angle. Clear lenses concentrate light for narrow viewing angles; diffused lenses spread light across wider viewing angles with reduced peak brightness.

Q: Are there brightness differences between these parts?

A: Yes. The MPC5BWC provides 25mcd while the MPC5BWD provides 15mcd. This 10mcd difference reflects the optical characteristics of the clear versus diffused lens design. Application requirements for brightness should be evaluated before substitution.

Q: What is the viewing angle difference?

A: The MPC5BWC has a 20° viewing angle while the MPC5BWD has a 45° viewing angle. The wider viewing angle of MPC5BWD allows visibility from a broader range of positions, while the narrower angle of MPC5BWC provides more focused light output.

Q: Are packaging and compliance specifications different?

A: The MPC5BWD is supplied in tray packaging and carries ROHS3 compliance certification. The MPC5BWC packaging specification is not provided. Both parts have MSL 1 (unlimited moisture sensitivity), identical ECCN and HTSUS classifications, and share the same manufacturer (Bivar Inc.) and series (MPC5).

Q: Why is MPC5BWC listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The MPC5BWD serves as the active equivalent within the MPC5 series, ensuring continued availability for new designs and replacement applications.

Q: Can I use MPC5BWD in applications requiring the exact 25mcd brightness of MPC5BWC?

A: No. If the application requires exactly 25mcd output, the brightness reduction to 15mcd in MPC5BWD may not meet specifications. Application brightness requirements must be verified before substitution.

Q: Are there any circuit modifications needed when switching from MPC5BWC to MPC5BWD?

A: No circuit modifications are required. Both parts operate at 4V with 25mA maximum current. Direct substitution in the circuit is electrically compatible.
