Key Parameters

Substitute Part Grouping Explanation

The MPR3ATW12.0 can be substituted with the MPR3ADW12.0 based on the following matching parameters:

Electrical Compatibility:

• Identical voltage rating: 2V
• Identical current rating: 30mA
• Same wavelength peak: 605nm

Mechanical Compatibility:

• Same lens size: 3mm, T-1
• Identical panel cutout dimensions: 0.24" (6.10mm)
• Identical termination style: Wire Leads - 12" (304.80mm)
• Same lens style: Round with Domed Top

Key Differences Affecting Application:

• Lens transparency: Clear (MPR3ATW12.0) vs. Diffused (MPR3ADW12.0)
• Viewing angle: 20° (MPR3ATW12.0) vs. 35° (MPR3ADW12.0)
• Luminous intensity: 40mcd (MPR3ATW12.0) vs. 25mcd (MPR3ADW12.0)
• Product status: Obsolete (MPR3ATW12.0) vs. Active (MPR3ADW12.0)

Parameter Comparison

Engineering Selection Recommendations

The MPR3ADW12.0 is the appropriate substitute for the obsolete MPR3ATW12.0. This alternative maintains full electrical and mechanical compatibility, ensuring drop-in compatibility in panel mounting applications. The MPR3ADW12.0 holds active product status with ROHS3 compliance, providing supply chain continuity and regulatory alignment for new designs and production.

Selection between these models depends on optical performance requirements. The MPR3ATW12.0 provides higher luminous intensity (40mcd) with a narrower viewing angle (20°), suitable for applications requiring directional, bright indication. The MPR3ADW12.0 offers broader angular visibility (35°) with lower luminous intensity (25mcd), appropriate for applications prioritizing wide-angle visibility over peak brightness.

Frequently Asked Questions (FAQ)

Q: Can MPR3ADW12.0 directly replace MPR3ATW12.0 in existing circuits? A: Yes. Both components share identical electrical ratings (2V, 30mA), mechanical form factor (3mm T-1 lens, 0.24" panel cutout), and termination style (12" wire leads), ensuring direct substitution without circuit modification.

Q: What is the primary functional difference between these two models? A: The primary difference is optical performance. MPR3ATW12.0 features a clear lens with 20° viewing angle and 40mcd output, while MPR3ADW12.0 has a diffused lens with 35° viewing angle and 25mcd output. Clear lenses provide directional, focused indication; diffused lenses distribute light over a wider viewing angle.

Q: Why is MPR3ATW12.0 listed as obsolete? A: Product obsolescence typically results from manufacturer discontinuation decisions. The active status of MPR3ADW12.0 within the same series provides a direct replacement path for ongoing procurement.

Q: Are there RoHS compliance differences? A: MPR3ADW12.0 is explicitly listed as ROHS3 compliant. RoHS compliance status for MPR3ATW12.0 is not specified in available documentation.

Q: How do the packaging differences affect component handling? A: MPR3ATW12.0 data does not specify packaging; MPR3ADW12.0 is packaged in bags. For component selection purposes, packaging does not affect electrical or mechanical compatibility, only procurement and inventory handling procedures.
