MPR5URC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR5URC is an industrial metal panel-mounted LED indicator manufactured by Bivar Inc., designed for applications requiring a red light signal with clear lens transparency. This component features a 5mm T-1 3/4 lens form factor with a round domed top, rated for 1.7V forward voltage and 20mA maximum current, delivering 400mcd brightness at a 30° viewing angle with a peak wavelength of 645nm.

The MPR5URC is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure component availability for production, and support ongoing maintenance of systems utilizing this indicator. Substitute parts must maintain compatibility with the 0.32" (8.13mm) round panel cutout and preserve functional performance within the application's electrical and mechanical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPR5URC must satisfy the following mandatory criteria:

Mechanical Compatibility (Non-negotiable):

• Lens size: 5mm, T-1 3/4 form factor
• Panel cutout shape: Round
• Panel cutout dimensions: 0.32" (8.13mm)
• Lens style: Round with domed top

Electrical Compatibility (Design-dependent):

• Lamp color: Red
• Maximum current rating: 20mA
• Forward voltage: Acceptable range determined by circuit design (1.7V nominal for MPR5URC)

Environmental Compatibility:

• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

The MPR5RD qualifies as a substitute based on matching mechanical form factor (5mm T-1 3/4 round domed lens, 0.32" round panel cutout), identical lamp color (red), identical maximum current rating (20mA), and equivalent moisture sensitivity level (MSL 1). Electrical parameter variations (forward voltage 2.1V vs. 1.7V; brightness 2mcd vs. 400mcd; wavelength 700nm vs. 645nm; viewing angle 35° vs. 30°) are acceptable within the scope of substitute part selection, provided the application circuit accommodates these differences.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The MPR5RD is a valid substitute for the MPR5URC based on mechanical and electrical compatibility within the defined parameter scope. Both components share identical mechanical specifications (5mm T-1 3/4 lens, round domed top, 0.32" round panel cutout) and identical maximum current rating (20mA), ensuring direct physical and electrical interface compatibility.

Product Status Consideration:

The MPR5URC is classified as obsolete, while the MPR5RD is active and currently in production. Selection of the MPR5RD ensures long-term component availability and supply chain continuity for new production runs and field replacements.

Compliance and Certification:

The MPR5RD carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in industrial applications. The MPR5URC compliance status is not specified in available documentation.

Electrical Parameter Variations:

The forward voltage difference (2.1V vs. 1.7V) requires circuit design verification to confirm the application can accommodate the higher voltage drop. The brightness difference (2mcd vs. 400mcd) and lens transparency difference (diffused vs. clear) represent significant optical characteristic changes that must be evaluated against application visibility requirements. The wavelength shift (700nm vs. 645nm) and viewing angle increase (35° vs. 30°) are secondary considerations dependent on specific application constraints.

Implementation Approach:

Direct substitution is mechanically feasible. Electrical and optical performance validation is required before production implementation to confirm the application tolerates the parameter variations listed in the comparison table.

Frequently Asked Questions (FAQ)

Q: Can the MPR5RD be directly installed in place of the MPR5URC without mechanical modification?

A: Yes. Both components feature identical mechanical specifications: 5mm T-1 3/4 lens form factor, round domed top style, and 0.32" (8.13mm) round panel cutout dimensions. No panel modification or mechanical adaptation is required for physical installation.

Q: What is the primary reason for substituting the MPR5URC?

A: The MPR5URC is classified as obsolete and no longer in production. The MPR5RD is an active product from the same manufacturer (Bivar Inc.) with matching mechanical form factor and electrical current rating, ensuring component availability for ongoing production and field service applications.

Q: Are there electrical compatibility concerns when substituting the MPR5RD for the MPR5URC?

A: The forward voltage differs by 0.4V (2.1V vs. 1.7V). The application circuit must be evaluated to confirm it can accommodate this voltage increase. The maximum current rating is identical (20mA), so current-limiting circuit design remains unchanged. Brightness and wavelength differences are secondary optical characteristics that depend on application visibility requirements.

Q: How do the optical characteristics differ between these two parts?

A: The MPR5URC features a clear colorless lens with 400mcd brightness and 645nm peak wavelength. The MPR5RD features a red-tinted diffused lens with 2mcd brightness and 700nm peak wavelength. The MPR5RD provides a wider viewing angle (35° vs. 30°). These differences affect visual output intensity and color perception and must be evaluated against application requirements.

Q: What is the packaging difference between the MPR5URC and MPR5RD?

A: The MPR5URC packaging is listed as unspecified. The MPR5RD is supplied in tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are both parts compliant with current environmental regulations?

A: The MPR5RD is ROHS3 compliant and REACH unaffected. The MPR5URC compliance status is not documented. The MPR5RD meets current regulatory requirements for industrial electronic components.

Q: What is the inventory status of these parts?

A: The MPR5URC has 976 pieces in stock (obsolete status). The MPR5RD has 1072 pieces in stock (active product). Long-term availability is assured only for the MPR5RD.
