Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MPR3HTW12.0 is based on electrical and mechanical compatibility within the MPR3 series. The substitute part MPR3HDW12.0 maintains identical electrical ratings (2V, 30mA), mechanical form factor (3mm T-1 lens, 0.24" panel cutout, 12-inch wire leads), and peak wavelength (625nm). The primary difference is lens transparency: the substitute features a diffused lens with 35° viewing angle compared to the clear lens with 20° viewing angle of the original part. This substitution is valid where the wider viewing angle and reduced brightness (30mcd versus 50mcd) are acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

The MPR3HDW12.0 serves as the active equivalent for the obsolete MPR3HTW12.0. Both components share identical electrical specifications (2V, 30mA) and mechanical compatibility (3mm T-1 form factor, 0.24" panel cutout, 12-inch wire leads). The MPR3HDW12.0 is currently in active production status with RoHS3 compliance certification, ensuring long-term availability and regulatory alignment.

Selection of the MPR3HDW12.0 substitute requires evaluation of optical performance differences. The diffused lens reduces brightness output from 50mcd to 30mcd and expands the viewing angle from 20° to 35°. Applications requiring the original narrow viewing angle and high brightness specification may require alternative component sourcing outside the MPR3 series.

Frequently Asked Questions (FAQ)

Q: Can the MPR3HDW12.0 directly replace the MPR3HTW12.0 in all applications?

A: Direct replacement is valid for electrical and mechanical compatibility. The MPR3HDW12.0 maintains identical voltage (2V), current (30mA), and physical form factor. However, optical characteristics differ: the substitute has a diffused lens with 35° viewing angle and 30mcd brightness versus the original clear lens with 20° viewing angle and 50mcd brightness. Applications sensitive to viewing angle or brightness must evaluate these differences.

Q: What are the key differences between these two parts?

A: The primary differences are lens transparency and optical performance. MPR3HTW12.0 features a clear lens optimized for narrow-angle, high-brightness applications. MPR3HDW12.0 features a diffused lens for wider-angle, lower-brightness applications. All other specifications including voltage, current, form factor, and wavelength are identical.

Q: Is the MPR3HDW12.0 RoHS compliant?

A: Yes, the MPR3HDW12.0 is RoHS3 compliant. The original MPR3HTW12.0 RoHS status is not specified in available documentation.

Q: What is the panel cutout compatibility?

A: Both parts use identical 0.24" (6.10mm) round panel cutouts, ensuring mechanical interchangeability in panel-mount applications.

Q: Are the wire lead lengths identical?

A: Yes, both components feature 12-inch (304.80mm) wire leads, maintaining identical termination compatibility.

Q: What is the moisture sensitivity rating for these components?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
