Key Parameters

Substitute Part Grouping Explanation

The MPR3ADW12.0 qualifies as a substitute for the MPR3ACW12.0 based on the following critical parameters that determine interchangeability:

Matching Parameters:

• Same manufacturer (Bivar Inc.)
• Same series (MPR3)
• Same lamp color (Amber)
• Same voltage rating (2V)
• Same current rating (30mA)
• Same panel cutout shape (Round)
• Same panel cutout dimensions (0.24" / 6.10mm)
• Same lens size and style (3mm T-1, Round with Domed Top)
• Same wavelength peak (605nm)
• Same termination style (Wire Leads - 12" / 304.80mm)
• Same MSL rating (1 - Unlimited)

Differing Parameters:

• Lens transparency: Clear (MPR3ACW12.0) versus Diffused (MPR3ADW12.0)
• Lens color: Colorless (MPR3ACW12.0) versus Amber (MPR3ADW12.0)
• Viewing angle: 20° (MPR3ACW12.0) versus 35° (MPR3ADW12.0)
• Millicandela rating: 40mcd (MPR3ACW12.0) versus 25mcd (MPR3ADW12.0)

These differences represent design variations within the same component family that accommodate different optical dispersion and brightness requirements while maintaining physical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MPR3ADW12.0 serves as a direct electrical and mechanical substitute for the obsolete MPR3ACW12.0. The primary consideration for selection is product status: the MPR3ACW12.0 is obsolete, while the MPR3ADW12.0 is active and maintains current manufacturing availability with 1069 units in stock. Both components share identical voltage, current, panel cutout geometry, lens size, and termination specifications.

The substitute part exhibits a wider viewing angle (35° versus 20°) and reduced brightness output (25mcd versus 40mcd) due to its diffused lens design. These optical differences reflect the inherent characteristics of diffused versus clear lenses and must be evaluated against specific application requirements. Both components are ROHS3 compliant where applicable and carry the same MSL rating.

Frequently Asked Questions (FAQ)

Q: Can the MPR3ADW12.0 directly replace the MPR3ACW12.0 in existing equipment? A: Both components share identical electrical ratings (2V, 30mA) and mechanical specifications (panel cutout dimensions, termination style, and wire lead length). Direct replacement is supported from a mounting and circuit perspective.

Q: What are the optical differences between these parts? A: The MPR3ACW12.0 features a clear lens with 20° viewing angle and 40mcd brightness. The MPR3ADW12.0 features a diffused amber lens with 35° viewing angle and 25mcd brightness. These differences affect light dispersion and intensity characteristics.

Q: Does the wider viewing angle of the MPR3ADW12.0 affect compatibility? A: Viewing angle is an optical property that affects light distribution. Applications requiring narrow, focused light output (20°) differ from those requiring broad dispersion (35°). This parameter must be evaluated against specific application requirements.

Q: Are there inventory or availability considerations for these parts? A: The MPR3ACW12.0 is obsolete with limited remaining stock (758 units). The MPR3ADW12.0 is active production with higher inventory (1069 units). For new designs and ongoing supply, the MPR3ADW12.0 is the recommended part for continued availability.

Q: Do both parts comply with the same environmental and regulatory standards? A: Both parts carry identical MSL ratings (1 - Unlimited), ECCN classification (EAR99), and HTSUS codes (8541.41.0000). Both are part of the same MPR3 series from Bivar Inc.
