Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPC3RTW12.0 are identified based on strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Forward Voltage: 2.1V
• Maximum Current: 20mA

Optical Parameters (Must Match):

• Lamp Color: Red
• Lens Color: Red
• Peak Wavelength: 700nm
• Viewing Angle: 20°

Mechanical Parameters (Must Match):

• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Panel Cutout Shape: Round
• Panel Cutout Dimensions: 0.24" (6.10mm)
• Termination Style: Wire Leads - 12" (304.80mm)

Allowable Variation:

• Lens Transparency: Clear or Diffused (affects light distribution characteristics but maintains functional compatibility)
• Millicandela Rating: Variation permitted within the same product family (affects brightness intensity)
• Product Status: Active or Obsolete (does not affect electrical or mechanical compatibility)

The MPC3RDW12.0 qualifies as a direct substitute based on these criteria, with the primary difference being lens transparency (diffused versus clear).

Parameter Comparison

Engineering Selection Recommendations

MPC3RDW12.0 as Primary Substitute:

The MPC3RDW12.0 is the direct equivalent substitute for the obsolete MPC3RTW12.0. Both components share identical electrical ratings (2.1V forward voltage, 20mA maximum current), mechanical form factors (3mm T-1 lens, 0.24-inch round panel cutout, 12-inch wire leads), and optical specifications (red lamp and lens color, 700nm peak wavelength, 20° viewing angle).

The MPC3RDW12.0 offers the following advantages:

• Product Status: Active production status ensures ongoing availability and supply chain continuity.
• Compliance Certifications: ROHS3 compliance and REACH unaffected status meet current regulatory requirements for electronic components in regulated markets.
• Moisture Sensitivity: MSL 1 rating (unlimited moisture sensitivity level) matches the original part, indicating no special storage or handling requirements.

Lens Transparency Consideration:

The primary functional difference between MPC3RTW12.0 and MPC3RDW12.0 is lens transparency. The MPC3RTW12.0 features a clear lens, while the MPC3RDW12.0 features a diffused lens. This difference affects light distribution characteristics:

• Clear lens: Produces a more focused, directional light beam
• Diffused lens: Distributes light more uniformly across a wider area

Both configurations maintain the specified 20° viewing angle and are electrically and mechanically interchangeable. Selection between clear and diffused variants depends on the specific visual signaling requirements of the application.

Brightness Consideration:

The MPC3RDW12.0 has a millicandela rating of 2mcd compared to 2.5mcd for the MPC3RTW12.0. This represents a 20% reduction in peak brightness intensity. For applications where brightness is a critical parameter, this difference must be evaluated against the specific visibility requirements of the installation environment.

Frequently Asked Questions (FAQ)

Q: Can the MPC3RDW12.0 be used as a direct replacement for the MPC3RTW12.0 in existing designs?

A: Yes. The MPC3RDW12.0 is electrically and mechanically equivalent to the MPC3RTW12.0. Both components have identical forward voltage (2.1V), maximum current (20mA), lens size (3mm T-1), panel cutout dimensions (0.24 inches), and wire lead length (12 inches). The components are pin-compatible and require no circuit modifications.

Q: What is the difference between the clear lens (MPC3RTW12.0) and diffused lens (MPC3RDW12.0)?

A: Lens transparency affects light distribution. The clear lens produces a more concentrated, directional light beam, while the diffused lens spreads light more uniformly. Both maintain the 20° viewing angle specification. The choice between clear and diffused depends on whether the application requires focused or dispersed illumination.

Q: Does the lower millicandela rating of the MPC3RDW12.0 (2mcd versus 2.5mcd) affect compatibility?

A: The millicandela rating indicates peak brightness intensity. The MPC3RDW12.0 produces approximately 80% of the brightness of the MPC3RTW12.0. Compatibility depends on the specific visibility requirements of the application. For applications where brightness is not a limiting factor, this difference is not significant. For applications requiring maximum brightness, the brightness reduction must be evaluated.

Q: Are there any compliance or regulatory differences between the MPC3RTW12.0 and MPC3RDW12.0?

A: The MPC3RDW12.0 carries ROHS3 compliance and REACH unaffected certifications. The MPC3RTW12.0 specifications do not include these compliance statements. Both components have identical Moisture Sensitivity Level (MSL 1, Unlimited), ECCN (EAR99), and HTSUS (8541.41.0000) classifications.

Q: What is the inventory status of these components?

A: The MPC3RTW12.0 (obsolete) has 642 pieces in stock. The MPC3RDW12.0 (active) has 849 pieces in stock. The active status of the MPC3RDW12.0 indicates ongoing manufacturing and supply availability.

Q: Are the wire leads identical between the two parts?

A: Yes. Both the MPC3RTW12.0 and MPC3RDW12.0 feature wire leads with 12-inch (304.80mm) length. The termination style, wire gauge, and lead configuration are identical.

Q: Can these components be used in applications requiring environmental protection or moisture resistance?

A: Both components have MSL 1 (Unlimited) ratings, indicating no special moisture sensitivity requirements. Standard storage and handling practices are sufficient. However, the ingress protection rating is not specified for either component. For applications requiring sealed or potted installations, additional environmental protection measures may be necessary depending on the specific application requirements.
