Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPR6-3WD110V is determined by the following critical parameters that must remain consistent across equivalent components:

Mandatory Matching Parameters:

• Voltage Rating: 110V
• Lamp Color: White
• Lens Transparency: Diffused
• Lens Style: Round with Flat Top
• Panel Cutout Shape: Round
• Viewing Angle: 45°
• Ingress Protection: IP54

Allowable Variation Parameters:

• Panel Cutout Dimensions: Variation permitted within mechanical design constraints
• Millicandela Rating: Variation permitted within acceptable brightness tolerance
• Termination Style: Variation permitted based on circuit integration requirements
• Product Status: Active status preferred for ongoing availability

The MPR8-3WD110V qualifies as a substitute based on matching all mandatory parameters while offering enhanced brightness (165mcd versus 145mcd) and alternative termination (Quick Connect versus Solder Lug).

Parameter Comparison

Engineering Selection Recommendations

The MPR8-3WD110V serves as the active equivalent for the obsolete MPR6-3WD110V. Selection of this substitute is based on the following engineering criteria:

Product Status Consideration: The MPR6-3WD110V is classified as obsolete, making the MPR8-3WD110V the appropriate active alternative from Bivar Inc. for continued component sourcing.

Compliance and Certification: The MPR8-3WD110V carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

Functional Equivalence: Both components maintain identical voltage rating (110V), lamp color (white), lens transparency (diffused), viewing angle (45°), and ingress protection (IP54) specifications, ensuring functional compatibility in existing circuit designs.

Physical Integration: Panel cutout dimension variation (0.23" to 0.31") requires mechanical panel redesign or adapter consideration. Termination style change from solder lug to quick connect requires electrical connection modification.

Performance Characteristics: The substitute provides enhanced brightness output (165mcd versus 145mcd), which is acceptable for applications where increased luminous intensity is not detrimental.

Frequently Asked Questions (FAQ)

Q: Can the MPR8-3WD110V directly replace the MPR6-3WD110V without modifications?

A: Direct replacement requires two modifications: (1) Panel cutout enlargement from 0.23" (5.84mm) to 0.31" (7.87mm) diameter, and (2) Electrical connection change from solder lug to quick connect termination. Functional operation remains equivalent when these mechanical and electrical changes are implemented.

Q: What are the key compatibility criteria for substitution?

A: Substitution is valid when the replacement component maintains 110V voltage rating, white lamp color, diffused lens transparency, round flat-top lens style, round panel cutout shape, 45° viewing angle, and IP54 ingress protection. All these parameters are matched between the main part and substitute.

Q: Does the brightness difference between 145mcd and 165mcd affect circuit design?

A: The 20mcd increase in the substitute represents approximately 14% higher brightness output. This variation falls within normal component tolerance ranges and does not require circuit redesign for standard indicator light applications.

Q: What is the significance of the termination style change?

A: The main part uses solder lug termination for permanent circuit connections, while the substitute uses quick connect termination for tool-free connection. This change requires modification of the connection interface but does not affect electrical performance or signal integrity.

Q: Is the ROHS3 compliance of the substitute relevant for existing designs?

A: ROHS3 compliance indicates the substitute meets current environmental and regulatory standards for electronic component manufacturing. This is advantageous for new production runs and ensures compliance with evolving regulatory requirements.

Q: Are there inventory considerations for component selection?

A: The MPR8-3WD110V is currently active with 855 pieces in stock, while the MPR6-3WD110V is obsolete with 1096 pieces remaining. For new designs and ongoing production, the active substitute ensures long-term component availability.
