Substitute Part Grouping Explanation

Substitution between MPR3GTW12.0 and MPR3GDW12.0 is based on the following allowed parameters:

Electrical Compatibility: Both parts operate at identical forward voltage (2.1V) and maximum current (30mA), ensuring direct circuit-level compatibility without modification to current-limiting resistor networks or power supply specifications.

Mechanical Compatibility: Both components share identical lens size (3mm, T-1), panel cutout shape (round), and panel cutout dimensions (0.24" / 6.10mm), confirming mechanical interchangeability in panel-mount applications. Both feature wire leads with 12" (304.80mm) length.

Optical Characteristics: Both parts emit green light at the same peak wavelength (568nm), maintaining color consistency in visual indication systems.

Differentiating Parameters: The primary differences are lens transparency (clear versus diffused) and viewing angle (20° versus 35°), along with brightness rating (40mcd versus 25mcd). These differences affect light distribution and intensity but do not prevent functional substitution based on application requirements.

Engineering Selection Recommendations

For Obsolete Part Replacement: The MPR3GDW12.0 is the designated substitute for the obsolete MPR3GTW12.0. The substitute part is currently in active production status with confirmed inventory availability (1463 units), ensuring supply chain continuity for new designs and maintenance applications.

Electrical Equivalence: Direct substitution is supported at the circuit level. Both parts operate at 2.1V forward voltage and 30mA maximum current, requiring no modification to existing current-limiting resistor calculations or power supply specifications.

Compliance Status: The MPR3GDW12.0 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement in regulated industries.

Optical Considerations: The substitute part features a diffused lens versus the clear lens of the original part, resulting in a wider viewing angle (35° versus 20°) and lower peak brightness (25mcd versus 40mcd). These optical differences must be evaluated against specific application requirements for visual indication distance and ambient lighting conditions.

Frequently Asked Questions (FAQ)

Q: Can MPR3GDW12.0 be used as a direct replacement for MPR3GTW12.0 in existing assemblies?

A: Yes, direct mechanical and electrical substitution is supported. Both parts share identical panel cutout dimensions (0.24" / 6.10mm), lens size (3mm T-1), wire lead length (12"), forward voltage (2.1V), and maximum current (30mA). No circuit modifications are required.

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

A: The main differences are lens transparency and optical characteristics. MPR3GTW12.0 features a clear lens with 20° viewing angle and 40mcd brightness. MPR3GDW12.0 features a diffused lens with 35° viewing angle and 25mcd brightness. Both emit green light at 568nm peak wavelength.

Q: Why is MPR3GTW12.0 listed as obsolete?

A: The part has been discontinued by the manufacturer. The MPR3GDW12.0 is the active equivalent available for new production and replacement applications.

Q: Will the diffused lens affect visibility in my application?

A: The diffused lens provides a wider viewing angle (35° versus 20°), making the indicator visible from a broader range of positions. However, peak brightness is lower (25mcd versus 40mcd). Application-specific evaluation of viewing distance and ambient lighting is necessary to confirm suitability.

Q: Are there any compliance differences between the two parts?

A: MPR3GDW12.0 carries ROHS3 compliance and REACH unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications and MSL rating of 1 (Unlimited).

Q: What is the inventory status of the substitute part?

A: MPR3GDW12.0 has 1463 units in stock as new original inventory, confirming availability for immediate procurement.
