Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPC3HTW12.0 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match exactly to establish a valid substitution relationship:

Mandatory Matching Parameters:

• Voltage: 2V
• Current: 30mA
• Lamp Color: Red
• Lens Size: 3mm, T-1
• Panel Cutout Shape: Round
• Panel Cutout Dimensions: 0.24" (6.10mm)
• Termination Style: Wire Leads - 12" (304.80mm)
• Lens Style: Round with Domed Top

Allowable Variation Parameters:

• Lens Transparency (Clear vs. Diffused) - affects light distribution and millicandela output
• Product Status (Obsolete vs. Active) - does not affect electrical or mechanical compatibility
• Packaging format - does not affect component function

The MPC3HDW12.0 qualifies as a substitute part because it maintains all mandatory electrical and mechanical parameters while varying only in lens transparency and product status.

Engineering Selection Recommendations

Primary Substitute: MPC3HDW12.0

The MPC3HDW12.0 is the direct substitute for the obsolete MPC3HTW12.0. Selection of this substitute is based on the following engineering factors:

Electrical Compatibility: Both parts operate at identical voltage (2V) and current (30mA) specifications, ensuring direct circuit compatibility without modification to drive circuitry or current-limiting resistor calculations.

Mechanical Compatibility: Panel cutout dimensions, lens size, termination style, and wire lead length are identical, enabling direct mechanical replacement in existing panel assemblies without modification to mounting hardware or wiring harnesses.

Optical Consideration: The MPC3HDW12.0 features a diffused lens versus the clear lens of the MPC3HTW12.0. This results in a reduction of peak brightness from 50mcd to 30mcd, with improved light distribution across a wider viewing area. The 20° viewing angle specification remains constant. Applications requiring uniform illumination across a broader viewing range benefit from the diffused lens design.

Product Status Advantage: The MPC3HDW12.0 carries Active product status, ensuring continued availability and supply chain support. The MPC3HTW12.0 is classified as Obsolete, making the substitute the recommended selection for new designs and ongoing production.

Compliance: The MPC3HDW12.0 is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can the MPC3HDW12.0 be used as a direct replacement for the MPC3HTW12.0 in existing assemblies?

A: Yes. The MPC3HDW12.0 is electrically and mechanically compatible with the MPC3HTW12.0. Both components share identical voltage, current, lens size, panel cutout dimensions, and wire lead specifications. No circuit modifications or mechanical rework is required.

Q: What is the difference between the clear lens (MPC3HTW12.0) and diffused lens (MPC3HDW12.0)?

A: The clear lens provides concentrated light output at 50mcd with a narrower light distribution pattern. The diffused lens scatters light more uniformly, reducing peak brightness to 30mcd but improving visibility across a wider viewing area. Both maintain the same 20° viewing angle specification. Selection depends on application requirements for brightness concentration versus uniform illumination.

Q: Does the reduction in millicandela rating from 50mcd to 30mcd affect circuit design?

A: No. The millicandela rating describes light output intensity, not electrical characteristics. Both parts operate at identical 2V and 30mA specifications. Circuit design, including current-limiting resistor values and power supply requirements, remains unchanged.

Q: Is the MPC3HDW12.0 available in the same packaging as the MPC3HTW12.0?

A: The MPC3HDW12.0 is supplied in Bag packaging, while the MPC3HTW12.0 packaging format is not specified in the provided data. Both components feature identical wire lead termination (12 inches) and mechanical form factor. Packaging format does not affect component function or compatibility.

Q: What is the inventory status of these parts?

A: The MPC3HTW12.0 (obsolete) has 786 pieces in stock. The MPC3HDW12.0 (active) has 778 pieces in stock. The active status of the MPC3HDW12.0 ensures continued availability for future orders.

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

A: The MPC3HDW12.0 is certified ROHS3 compliant. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications and Moisture Sensitivity Level 1 (Unlimited) ratings. The ROHS3 compliance of the substitute part meets current environmental regulations.
