Equivalent & Substitute Parts for MPR6-3RD110V

Part Overview

The MPR6-3RD110V is a panel-mounted indicator light manufactured by Bivar Inc., designed for 110V applications with red diffused illumination. This component features a 3mm round lens with a flat top, 45° viewing angle, and solder lug termination. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPR6-3RD110V is determined by strict alignment of electrical and optical parameters. The following criteria establish functional equivalence:

Electrical Parameters (Non-negotiable):

• Voltage rating must be 110V
• Lamp color must be red (625nm peak wavelength)
• Millicandela rating must be 20mcd

Optical Parameters (Non-negotiable):

• Lens transparency must be diffused
• Viewing angle must be 45°

Mechanical Parameters (Conditional):

• Panel cutout shape must be round
• Lens style must be round with flat top
• Ingress protection must be IP54

Connection Parameters (Conditional):

• Termination style may vary if mechanical and electrical integration is compatible with the application circuit

The MPR8-3RD110V qualifies as a substitute based on matching all electrical and optical parameters. Mechanical differences in panel cutout dimensions (0.31" vs. 0.23") and termination style (quick connect vs. solder lug) require evaluation against specific installation requirements.

Engineering Selection Recommendations

For Direct Replacement (Solder Lug Termination Required):

The MPR6-3RD110V is obsolete. The MPR8-3RD110V is the active equivalent from Bivar Inc. with identical electrical and optical specifications. However, the MPR8-3RD110V uses quick connect termination (0.110" / 2.8mm) instead of solder lug termination. If solder lug connection is mandatory for your application, alternative sourcing or custom termination adaptation is required.

For New Designs or Flexible Integration:

The MPR8-3RD110V is recommended as the primary substitute. It maintains all critical electrical and optical parameters (110V, red, 20mcd, 625nm, diffused, 45° viewing angle, IP54). The larger panel cutout dimension (0.31" vs. 0.23") requires panel modification or redesign. The quick connect termination is compatible with standard 0.110" (2.8mm) female connectors, eliminating soldering requirements.

Compliance Status:

Both parts carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000) and moisture sensitivity ratings (MSL 1 - Unlimited). The MPR8-3RD110V holds RoHS3 compliance certification, meeting current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the MPR8-3RD110V directly replace the MPR6-3RD110V in existing assemblies?

A: Electrical and optical compatibility is complete. Mechanical compatibility depends on two factors: (1) panel cutout size must accommodate the larger 0.31" (7.87mm) diameter of the MPR8-3RD110V versus the 0.23" (5.84mm) of the original, and (2) termination method differs—the substitute uses quick connect instead of solder lug. Panel modification and connector adaptation may be necessary.

Q: Are the brightness and color specifications identical?

A: Yes. Both parts deliver 20mcd brightness with 625nm peak wavelength red illumination, diffused lens transparency, and 45° viewing angle. Visual performance is equivalent.

Q: What is the significance of the different panel cutout dimensions?

A: The MPR8-3RD110V requires a 0.31" (7.87mm) round cutout, compared to 0.23" (5.84mm) for the original. Existing panel tooling designed for the MPR6-3RD110V will not accommodate the larger substitute without modification.

Q: Does the quick connect termination affect electrical performance?

A: No. The quick connect termination (0.110" / 2.8mm female connector interface) provides equivalent electrical connection to solder lug termination. The connection method differs, but electrical characteristics remain identical.

Q: Is the MPR8-3RD110V suitable for the same environmental conditions?

A: Yes. Both parts carry IP54 ingress protection rating and MSL 1 (Unlimited) moisture sensitivity classification, indicating identical environmental performance specifications.

Q: Why is the MPR6-3RD110V obsolete?

A: Product status reflects manufacturer discontinuation. The MPR8-3RD110V represents the active product line continuation from Bivar Inc. with equivalent functionality.
