Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC3BWTW12.0 is based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant across substitute parts:

• Manufacturer: Bivar Inc.
• Series: MPC3
• Lamp Color: Blue
• Voltage Rating: 4V
• Current Rating: 25mA
• Panel Cutout Dimensions: 0.24" (6.10mm)
• Lens Size: 3mm, T-1
• Termination Style: Wire Leads - 12" (304.80mm)
• Wavelength - Peak: 430nm

The MPC3BWDW12.0 qualifies as a substitute part because it maintains all critical electrical parameters and mechanical form factors. The primary differences—lens transparency (diffused versus clear) and viewing angle (35° versus 20°)—represent functional variations that do not prevent substitution in applications where the optical characteristics are acceptable.

Engineering Selection Recommendations

The MPC3BWDW12.0 is the active equivalent for the obsolete MPC3BWTW12.0. Selection of this substitute is supported by the following factors:

Product Status: The MPC3BWDW12.0 maintains active production status, ensuring long-term supply availability and eliminating obsolescence risk associated with the MPC3BWTW12.0.

Electrical Compatibility: Both parts operate at identical voltage (4V) and current (25mA) specifications, ensuring direct circuit compatibility without modification to power supply or current-limiting resistor calculations.

Mechanical Compatibility: Identical panel cutout dimensions (0.24" / 6.10mm), lens size (3mm T-1), and wire lead length (12" / 304.80mm) enable direct mechanical substitution in existing panel assemblies.

Compliance: The MPC3BWDW12.0 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Optical Differences: The substitute part features a diffused lens transparency and wider 35° viewing angle compared to the clear lens and 20° viewing angle of the main part. The millicandela rating decreases from 15mcd to 10mcd. These optical characteristics must be evaluated against specific application requirements to determine acceptability.

Frequently Asked Questions (FAQ)

Q: Can the MPC3BWDW12.0 be used as a direct replacement for the MPC3BWTW12.0 in existing designs?

A: The MPC3BWDW12.0 provides electrical and mechanical compatibility. However, the diffused lens and wider viewing angle represent functional differences that must be assessed against application requirements. If the original design depends on the clear lens or narrow 20° viewing angle, optical performance will differ.

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

A: The primary differences are lens transparency (clear versus diffused), viewing angle (20° versus 35°), and brightness output (15mcd versus 10mcd). All electrical parameters, mechanical dimensions, and termination specifications remain identical.

Q: Why is the MPC3BWTW12.0 listed as obsolete?

A: The MPC3BWTW12.0 is classified as obsolete by the manufacturer. The MPC3BWDW12.0 is the active production equivalent within the MPC3 series.

Q: Are there any compliance or regulatory differences between these parts?

A: The MPC3BWDW12.0 carries ROHS3 compliance and REACH unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: Will the panel cutout dimensions require modification?

A: No. Both parts use identical 0.24" (6.10mm) round panel cutout dimensions, eliminating the need for mechanical panel modifications.

Q: What is the impact of the reduced millicandela rating on system performance?

A: The MPC3BWDW12.0 produces 10mcd compared to 15mcd for the MPC3BWTW12.0. This 33% reduction in peak brightness, combined with the diffused lens, results in lower intensity but wider light distribution. Application-specific visibility requirements must be evaluated.
