Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC3BWCW12.0 is based on the following electrical and mechanical parameters:

Critical Compatibility Parameters:

• Voltage Rating: 4V (exact match required)
• Current Rating: 25mA (exact match required)
• Panel Cutout Dimensions: 0.24" (6.10mm) Round (exact match required)
• Lens Size: 3mm, T-1 (exact match required)
• Termination Style: Wire Leads - 12" (304.80mm) (exact match required)
• Lamp Color: Blue (same color family)

Parameters Permitting Variation:

• Lens Transparency: Clear to Diffused (optical characteristic difference acceptable for substitution)
• Viewing Angle: 20° to 35° (field-of-view variation within acceptable operational range)
• Millicandela Rating: 15mcd to 10mcd (brightness reduction acceptable for indicator-class applications)
• Lens Color: Colorless to Blue (color treatment variation)

The MPC3BWDW12.0 qualifies as a direct substitute based on identical electrical ratings, mechanical dimensions, and mounting requirements, with acceptable variations in optical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MPC3BWDW12.0 is the qualified substitute for the obsolete MPC3BWCW12.0. Selection of this substitute is supported by:

• Product Status: The MPC3BWDW12.0 maintains Active status, ensuring continued availability and manufacturing support.
• Regulatory Compliance: The MPC3BWDW12.0 is ROHS3 Compliant, meeting current environmental and regulatory requirements.
• Electrical Equivalence: Both parts share identical voltage (4V) and current (25mA) ratings, ensuring direct functional compatibility in circuit designs.
• Mechanical Compatibility: Both parts feature identical panel cutout dimensions (0.24" / 6.10mm Round) and termination style (Wire Leads - 12"), eliminating redesign requirements for panel mounting and wiring.
• Optical Variation Acceptability: The transition from a clear 20° lens to a diffused 35° viewing angle represents an acceptable trade-off in indicator-class LED applications, providing wider visibility at the cost of reduced peak brightness (15mcd to 10mcd).

Frequently Asked Questions (FAQ)

Q: Are the MPC3BWCW12.0 and MPC3BWDW12.0 electrically interchangeable?

A: Yes. Both parts are rated at 4V and 25mA, making them electrically interchangeable in circuit designs without modification to voltage or current-limiting components.

Q: Will the MPC3BWDW12.0 fit in a panel designed for the MPC3BWCW12.0?

A: Yes. Both parts have identical panel cutout dimensions of 0.24" (6.10mm) and the same mounting style, requiring no modifications to existing panel openings or mechanical fixtures.

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

A: The primary differences are optical: the MPC3BWCW12.0 has a clear lens with a narrower 20° viewing angle and higher brightness (15mcd), while the MPC3BWDW12.0 has a diffused blue lens with a wider 35° viewing angle and lower brightness (10mcd).

Q: Which part should be selected for a new design?

A: The MPC3BWDW12.0 is the recommended selection for new designs due to its Active product status, ROHS3 Compliance, and ongoing manufacturer support.

Q: Are there any compatibility issues with existing wire lead terminations?

A: No. Both parts feature identical wire lead terminations of 12" (304.80mm), ensuring direct compatibility with existing wiring harnesses and connector interfaces.
