MPR6-3BWD110V Equivalent & Substitute Parts

Part Overview

The MPR6-3BWD110V is a panel-mounted indicator light manufactured by Bivar Inc., featuring a blue diffused lens with 110V operation and solder lug termination. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The 53mm form factor with round flat-top lens design and 45° viewing angle serves applications requiring visual status indication in industrial control panels and equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPR6-3BWD110V is based on the following electrical and mechanical parameters that must remain constant or compatible:

Critical Matching Parameters:

• Voltage Rating: 110V (must be identical)
• Lamp Color: Blue (must be identical for functional equivalence)
• Lens Transparency: Diffused (must be identical for optical performance)
• Viewing Angle: 45° (must be identical for visibility requirements)
• Panel Cutout Shape: Round (must be identical for mechanical fit)
• Ingress Protection: IP54 (must be maintained for environmental protection)

Allowable Variation Parameters:

• Panel Cutout Dimensions: Variation permitted if mechanical mounting can be accommodated
• Millicandela Rating: Variation permitted if brightness increase does not conflict with application requirements
• Wavelength - Peak: Minor variation permitted within blue spectrum range
• Termination Style: Variation permitted if electrical connection method is compatible with circuit design

The MPR8-3BWD110V qualifies as a substitute based on matching all critical parameters while offering improved brightness (40mcd vs. 20mcd) and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The MPR8-3BWD110V serves as an active equivalent to the obsolete MPR6-3BWD110V when the following conditions are met:

1. Mechanical Accommodation: The panel cutout must be enlarged from 0.23" (5.84mm) to 0.31" (7.87mm) to accommodate the substitute part. This modification is feasible in new panel designs or retrofit applications where panel material permits enlargement.

2. Electrical Connection Modification: The termination style differs between parts. The main part uses solder lug termination, while the substitute uses quick connect terminals (0.110" / 2.8mm). Circuit board or wiring harness modification is required to accommodate this change.

3. Brightness Increase: The substitute provides double the brightness (40mcd vs. 20mcd). This enhancement is compatible with applications where increased visibility is acceptable or beneficial. Applications with strict brightness specifications must evaluate whether the increased output affects system performance.

4. Regulatory Compliance: The MPR8-3BWD110V carries ROHS3 compliance certification, meeting current environmental and regulatory standards. The main part's compliance status is not specified in available documentation.

5. Product Availability: The substitute is actively manufactured with 1041 units in stock, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the MPR8-3BWD110V be used as a direct drop-in replacement for the MPR6-3BWD110V?

A: No. While electrical parameters are compatible, two modifications are required: (1) panel cutout enlargement from 5.84mm to 7.87mm, and (2) termination connection change from solder lug to quick connect terminals. These changes prevent true drop-in replacement without circuit and panel modifications.

Q: What is the impact of the increased millicandela rating (40mcd vs. 20mcd)?

A: The substitute provides twice the light output. For applications where brightness is not constrained by specification, this enhancement improves visibility. Applications with strict brightness requirements or light-sensitive environments must evaluate whether increased output is acceptable.

Q: Are the blue wavelengths compatible between the two parts?

A: Yes. The main part operates at 465nm peak wavelength while the substitute operates at 470nm. Both wavelengths fall within the blue spectrum range and produce visually equivalent blue indication. The 5nm difference is imperceptible to human vision.

Q: What does the panel cutout dimension difference mean for my application?

A: The substitute requires a larger panel opening (7.87mm vs. 5.84mm). In new designs, this is accommodated during panel fabrication. In retrofit or repair scenarios, the existing panel cutout must be enlarged, which may not be feasible depending on panel material and surrounding component placement.

Q: Is the quick connect termination compatible with my solder lug wiring?

A: No. Quick connect terminals require female spade connectors (0.110" / 2.8mm), while solder lug termination requires direct soldering. Wiring harness modification or adapter solutions are necessary for compatibility.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The MPR8-3BWD110V carries ROHS3 compliance certification, meeting current environmental regulations. The main part's compliance status is not documented, making the substitute preferable for new designs subject to regulatory requirements.

Q: Are both parts manufactured by the same company?

A: Yes. Both the MPR6-3BWD110V and MPR8-3BWD110V are manufactured by Bivar Inc., ensuring design consistency and compatibility with Bivar's product ecosystem.

Q: What is the IP54 ingress protection rating?

A: IP54 indicates protection against dust ingress (5) and water splash from any direction (4). Both parts maintain this rating, ensuring equivalent environmental protection in panel-mounted applications.

Q: Can I use the substitute in applications where the main part is currently installed?

A: Substitution is possible only after confirming: (1) panel cutout can be enlarged to 7.87mm, (2) circuit wiring can be modified to accept quick connect terminals, (3) increased brightness (40mcd) does not conflict with application requirements, and (4) the 5nm wavelength shift is acceptable for the application.
