LED Panel Indicator MPR5BWCW12.0 Equivalent & Substitute Parts

Part Overview

The MPR5BWCW12.0 is a panel-mounted LED indicator manufactured by Bivar Inc., featuring a blue clear lens with 12-inch wire leads. This component is classified as obsolete, indicating discontinued production and limited availability for new procurement. The part operates at 4V with a maximum current of 25mA and provides a 25° viewing angle with 30mcd brightness output at a peak wavelength of 430nm.

Due to its obsolete status, identifying equivalent substitute parts is essential for system redesign, maintenance, and long-term supply chain planning. Substitute parts must maintain electrical compatibility while accommodating potential differences in optical characteristics and product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPR5BWCW12.0 is determined by strict adherence to critical electrical and mechanical parameters. The following parameters must remain constant across any substitute part:

Critical Parameters (Non-Negotiable):

• Voltage: 4V
• Current: 25mA
• Lamp Color: Blue
• Lens Size: 5mm, T-1 3/4
• Panel Cutout Dimensions: 0.32" (8.13mm)
• Termination Style: Wire Leads - 12" (304.80mm)

Application-Dependent Parameters (Substitution Allowed with Design Review):

• Viewing Angle: 25° (original) vs. 40° (substitute)
• Millicandela Rating: 30mcd (original) vs. 15mcd (substitute)
• Lens Transparency: Clear (original) vs. Diffused (substitute)

The substitute part MPR5BWDW12.0 maintains all critical electrical and mechanical parameters while introducing differences in optical characteristics. These differences reflect the transition from a clear lens to a diffused lens configuration, which affects light distribution and intensity perception.

Parameter Comparison

Engineering Selection Recommendations

Obsolescence Status: The MPR5BWCW12.0 is classified as obsolete, making the active substitute MPR5BWDW12.0 the appropriate choice for new designs and ongoing procurement requirements.

Electrical Compatibility: Both parts operate at identical voltage and current specifications (4V, 25mA), ensuring direct electrical substitution without circuit modification.

Mechanical Compatibility: Panel mounting dimensions, lens size, and wire lead configuration are identical, allowing direct mechanical replacement in existing panel assemblies.

Optical Differences: The substitute part introduces a diffused lens with blue coloration, replacing the clear colorless lens. This results in:

• Increased viewing angle (40° vs. 25°)
• Reduced peak brightness (15mcd vs. 30mcd)
• Broader light distribution pattern

Compliance Status: Both parts maintain identical MSL (1 - Unlimited), ECCN (EAR99), and HTSUS classifications, with the substitute offering ROHS3 compliance and REACH unaffected status.

Inventory Availability: The substitute part MPR5BWDW12.0 is currently in active production with 1148 units in stock, compared to the obsolete main part with limited remaining inventory of 1141 units.

Frequently Asked Questions (FAQ)

Q: Can MPR5BWDW12.0 be used as a direct replacement for MPR5BWCW12.0 in all applications?

A: Electrical and mechanical compatibility is complete. Optical differences require application review. The substitute provides wider viewing angle (40° vs. 25°) and lower peak brightness (15mcd vs. 30mcd) due to diffused lens design. Applications requiring narrow-angle, high-intensity indication may require design adjustment.

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

A: The main difference is lens configuration. MPR5BWCW12.0 features a clear colorless lens with focused light output (25° viewing angle, 30mcd). MPR5BWDW12.0 features a diffused blue lens with dispersed light output (40° viewing angle, 15mcd). Both maintain identical electrical ratings and mechanical dimensions.

Q: Are there any compliance or certification differences?

A: The substitute part MPR5BWDW12.0 includes ROHS3 compliance certification and REACH unaffected status. Both parts share identical ECCN (EAR99) and HTSUS classifications. Moisture sensitivity levels are identical (MSL 1 - Unlimited).

Q: What is the impact of the diffused lens on visibility?

A: The diffused lens distributes light over a wider viewing angle (40° vs. 25°), making the indicator visible from more positions. However, peak brightness is reduced (15mcd vs. 30mcd), resulting in lower intensity at the center viewing axis. Applications requiring high-intensity indication at narrow angles should evaluate this trade-off.

Q: Is the 12-inch wire lead length identical on both parts?

A: Yes. Both MPR5BWCW12.0 and MPR5BWDW12.0 feature identical wire lead termination of 12 inches (304.80mm), ensuring direct mechanical compatibility in existing assemblies.

Q: What is the current inventory status for each part?

A: MPR5BWCW12.0 (obsolete) has 1141 units in stock. MPR5BWDW12.0 (active) has 1148 units in stock. The active substitute is recommended for new procurement to ensure long-term supply continuity.
