MPC5BWT LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPC5BWT is a panel-mounted LED indicator manufactured by Bivar Inc., designed for applications requiring a blue light-emitting diode with wire termination. This component features a 430nm peak wavelength, 30mcd brightness rating, and operates at 4V with a maximum current of 25mA. The MPC5BWT is classified as obsolete, necessitating identification of active substitute components that maintain electrical and mechanical compatibility for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC5BWT is determined by strict alignment of electrical and mechanical parameters. The following criteria establish compatibility:

Electrical Compatibility Requirements:

• Lamp color must be blue (430nm wavelength range)
• Operating voltage must be 4V
• Maximum current rating must be 25mA or greater
• Millicandela rating and viewing angle may vary within application tolerance

Mechanical Compatibility Requirements:

• Lens size must be 5mm, T-1 3/4
• Panel cutout shape must be round
• Panel cutout dimensions must be 0.32" (8.13mm)
• Lens style must be round with domed top
• Termination must be wire-based

The MPC5BWD qualifies as a substitute based on matching electrical voltage and current specifications, identical mechanical dimensions, and equivalent series classification within the MPC5 product line.

Parameter Comparison

Engineering Selection Recommendations

The MPC5BWD is an active substitute for the obsolete MPC5BWT. Both components share identical electrical ratings (4V, 25mA) and mechanical specifications (5mm T-1 3/4 lens, 0.32" round panel cutout), ensuring direct form-fit-function replacement in panel-mount applications.

Differences in optical characteristics exist:

• The MPC5BWT provides 30mcd brightness with a 20° viewing angle and clear lens transparency
• The MPC5BWD provides 15mcd brightness with a 45° viewing angle and diffused lens transparency

These optical variations result in different light distribution patterns. The MPC5BWT concentrates light output in a narrow 20° cone, while the MPC5BWD disperses light across a wider 45° cone with reduced peak intensity. Selection between these variants depends on application-specific visibility requirements and viewing geometry.

Compliance Status: Both components are classified as MSL 1 (Unlimited moisture sensitivity), ROHS3 compliant (MPC5BWD), REACH unaffected, and EAR99 export classification. The MPC5BWD is currently in active production with 665 units in stock, while the MPC5BWT is obsolete with 863 units remaining in inventory.

Frequently Asked Questions (FAQ)

Q: Can the MPC5BWD directly replace the MPC5BWT in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both components operate at 4V with 25mA maximum current and share identical panel cutout dimensions (0.32" round). However, the optical characteristics differ: the MPC5BWT delivers 30mcd at 20°, while the MPC5BWD delivers 15mcd at 45°. Verify that your application can accommodate the reduced peak brightness and wider light distribution of the MPC5BWD.

Q: What is the primary difference between these two parts?

A: The MPC5BWT features a clear lens with narrow 20° viewing angle and higher brightness (30mcd), optimized for concentrated light output. The MPC5BWD features a diffused lens with wider 45° viewing angle and lower brightness (15mcd), optimized for distributed light output. Both use identical 430nm blue wavelength and 5mm T-1 3/4 form factor.

Q: Are there packaging differences between MPC5BWT and MPC5BWD?

A: The MPC5BWT is supplied in standard packaging, while the MPC5BWD is supplied in tray packaging. Both are MSL 1 rated with unlimited moisture sensitivity, requiring no special storage conditions.

Q: Why is the MPC5BWT classified as obsolete?

A: The MPC5BWT is no longer in active production. The MPC5BWD serves as the active replacement within the MPC5 series, offering equivalent electrical performance with alternative optical characteristics suited to broader application requirements.

Q: What compliance certifications apply to these components?

A: Both the MPC5BWT and MPC5BWD are classified as EAR99 for export control and HTSUS 8541.41.0000 for tariff purposes. The MPC5BWD is ROHS3 compliant and REACH unaffected. Both components have MSL 1 rating, indicating no moisture sensitivity restrictions.
