Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MPR5BWT is based on strict electrical and mechanical compatibility within the MPR5 series. The substitute part MPR5BWDW12.0 maintains the following critical parameters:

Electrical Compatibility:

• Identical voltage rating: 4V
• Identical maximum current rating: 25mA
• Identical peak wavelength: 430nm
• Same lamp color: Blue

Mechanical Compatibility:

• Identical panel cutout shape: Round
• Identical panel cutout dimensions: 0.32" (8.13mm)
• Identical lens size: 5mm, T-1 3/4
• Identical lens style: Round with Domed Top
• Same series designation: MPR5

Allowed Parameter Variations: The MPR5BWDW12.0 substitute differs in the following parameters, which are acceptable for substitution purposes:

• Lens transparency: Diffused (vs. Clear in MPR5BWT)
• Millicandela rating: 15mcd (vs. 25mcd in MPR5BWT)
• Viewing angle: 40° (vs. 25° in MPR5BWT)
• Termination style: Wire leads 12" (vs. unspecified in MPR5BWT)
• Product status: Active (vs. Obsolete in MPR5BWT)

Parameter Comparison

Engineering Selection Recommendations

The MPR5BWDW12.0 is the designated substitute for the obsolete MPR5BWT based on electrical and mechanical parameter alignment. Selection of this substitute is supported by the following factors:

Product Status: The MPR5BWDW12.0 maintains Active product status, ensuring continued availability and supply chain reliability compared to the Obsolete MPR5BWT.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining consistent export and tariff compliance.

Moisture Sensitivity: Both parts are rated MSL 1 (Unlimited), indicating equivalent environmental robustness for storage and handling.

Electrical Ratings: Identical voltage and current specifications ensure direct electrical compatibility in existing circuit designs without modification to current-limiting resistor values or power supply requirements.

Mechanical Fit: Identical panel cutout dimensions and lens size ensure direct mechanical compatibility with existing panel-mount installations.

Frequently Asked Questions (FAQ)

Q: Can MPR5BWDW12.0 be used as a direct replacement for MPR5BWT in existing designs?

A: Yes, from electrical and mechanical perspectives. Both parts share identical voltage (4V), current (25mA), panel cutout dimensions (0.32"/8.13mm), and lens size (5mm T-1 3/4). The primary design consideration is the difference in lens transparency (Diffused vs. Clear) and millicandela rating (15mcd vs. 25mcd), which affect light output characteristics.

Q: What is the impact of the Diffused lens on the MPR5BWDW12.0 compared to the Clear lens on MPR5BWT?

A: The Diffused lens on MPR5BWDW12.0 provides a wider viewing angle (40° vs. 25°) but lower peak brightness (15mcd vs. 25mcd). This results in more dispersed light distribution across a broader viewing area with reduced intensity at the center axis.

Q: Does the 12-inch wire lead length on MPR5BWDW12.0 affect compatibility?

A: The wire lead length is a termination feature that does not affect electrical or mechanical compatibility. Applications requiring different lead lengths must address this through circuit design or mechanical assembly modifications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical ECCN (EAR99), HTSUS (8541.41.0000), and MSL (1 - Unlimited) classifications. The MPR5BWDW12.0 includes additional RoHS3 Compliance and REACH Unaffected certifications, indicating enhanced regulatory alignment with current standards.

Q: What is the inventory status for these parts?

A: MPR5BWT has 1150 pieces in stock (Obsolete status). MPR5BWDW12.0 has 1148 pieces in stock (Active status), providing equivalent availability with the advantage of ongoing product support.
