Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPR3BWCW12.0 must maintain compatibility across the following critical parameters:

Electrical Compatibility: Voltage rating (4V) and maximum current (25mA) must remain constant to ensure proper operation within existing circuit designs without modification.

Mechanical Compatibility: Lens size (3mm, T-1), panel cutout shape (round), and panel cutout dimensions (0.24" / 6.10mm) must be identical to ensure physical fit within panel-mounted applications. Termination style (wire leads - 12" length) must match to maintain harness compatibility.

Optical Compatibility: Peak wavelength (430nm) and lamp color (blue) must be preserved. Lens color and transparency may vary within the blue LED product family, provided the optical output remains functionally equivalent for the intended application.

Environmental Compliance: Moisture Sensitivity Level (MSL 1 - Unlimited) establishes the baseline environmental rating for substitute selection.

The MPR3BWDW12.0 qualifies as a substitute based on these criteria, with documented variations in lens transparency and viewing angle characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MPR3BWDW12.0

The MPR3BWDW12.0 is the qualified substitute for the obsolete MPR3BWCW12.0. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: Both parts operate at identical voltage (4V) and current (25mA) ratings, ensuring direct circuit compatibility without modification.

Mechanical Equivalence: Identical lens size (3mm, T-1), panel cutout dimensions (0.24" / 6.10mm), and wire lead termination (12" length) confirm physical interchangeability in panel-mounted applications.

Optical Compatibility: Both parts emit blue light at the same peak wavelength (430nm). The MPR3BWDW12.0 features a diffused lens with blue coloration compared to the clear colorless lens of the main part. This results in a wider viewing angle (35° versus 20°) and lower brightness output (10mcd versus 15mcd). These optical variations are acceptable substitutions when the application does not require the specific narrow viewing angle or high brightness of the original part.

Product Status and Compliance: The MPR3BWDW12.0 is listed as active with ROHS3 compliance certification, ensuring ongoing availability and regulatory alignment for new designs or production continuity.

Inventory Availability: The MPR3BWDW12.0 has 1,045 units in stock, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the MPR3BWDW12.0 be used as a direct replacement for the MPR3BWCW12.0 in all applications?

A: The MPR3BWDW12.0 is electrically and mechanically compatible with the MPR3BWCW12.0. However, the optical characteristics differ. The substitute has a wider viewing angle (35° versus 20°) and lower brightness (10mcd versus 15mcd). Applications requiring the specific narrow viewing angle or high brightness of the original part must evaluate whether these differences affect performance.

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

A: The primary differences are lens transparency (clear versus diffused), lens color (colorless versus blue), viewing angle (20° versus 35°), and brightness output (15mcd versus 10mcd). Electrical specifications (4V, 25mA) and mechanical dimensions are identical.

Q: Will the MPR3BWDW12.0 fit in the same panel cutout as the MPR3BWCW12.0?

A: Yes. Both parts have identical panel cutout dimensions (0.24" / 6.10mm round) and lens size (3mm, T-1), ensuring physical interchangeability in panel-mounted installations.

Q: What is the significance of the diffused lens on the MPR3BWDW12.0?

A: The diffused lens scatters light over a wider viewing angle (35° versus 20°), making the indicator visible from a broader range of viewing positions. This results in lower peak brightness (10mcd versus 15mcd) but improved visibility across multiple angles.

Q: Is the MPR3BWDW12.0 RoHS compliant?

A: Yes. The MPR3BWDW12.0 is ROHS3 compliant, meeting current regulatory requirements for electronic components.

Q: Why is the MPR3BWCW12.0 listed as obsolete?

A: The MPR3BWCW12.0 is obsolete, indicating it is no longer manufactured or supported by Bivar Inc. The MPR3BWDW12.0 is the active substitute within the MPR3 series.
