Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the MPR5ATW12.0 is based on strict electrical and mechanical parameter matching within the MPR5 series. The following criteria determine substitution eligibility:

Mandatory Matching Parameters:

• Lamp color: Amber
• Operating voltage: 2V
• Maximum current: 30mA
• Lens size: 5mm, T-1 3/4
• Panel cutout dimensions: 0.32" (8.13mm)
• Termination: Wire leads, 12-inch length
• Peak wavelength: 605nm

Allowable Variations:

• Lens transparency (Clear to Diffused)
• Viewing angle (35° to 40°)
• Millicandela rating (40mcd to 25mcd)
• Product status (Obsolete to Active)
• Packaging configuration

The MPR5ADW12.0 qualifies as a direct substitute based on these criteria.

Engineering Selection Recommendations

Primary Substitute: MPR5ADW12.0

The MPR5ADW12.0 is the qualified substitute for the obsolete MPR5ATW12.0. Selection of this component is supported by the following engineering factors:

Electrical Compatibility: Both components operate at identical voltage (2V) and current (30mA) specifications, ensuring direct circuit compatibility without modification to power supply or current-limiting resistor values.

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

Optical Characteristics: Both components emit amber light at 605nm peak wavelength. The substitute features a diffused lens transparency compared to the clear lens of the main part, resulting in a 15mcd reduction in millicandela rating (40mcd to 25mcd) and a 5° increase in viewing angle (35° to 40°). These variations remain within acceptable parameters for panel indicator applications.

Product Status Advantage: The MPR5ADW12.0 is classified as Active with RoHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete status of the original component.

Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the MPR5ADW12.0 replace the MPR5ATW12.0 in existing designs?

A: Yes. The MPR5ADW12.0 is electrically and mechanically compatible. Both components operate at 2V, 30mA, and share identical panel cutout dimensions (0.32" / 8.13mm) and 12-inch wire lead termination. No circuit modifications are required.

Q: What is the difference between the Clear lens (MPR5ATW12.0) and Diffused lens (MPR5ADW12.0)?

A: The Clear lens provides higher brightness concentration (40mcd) with a narrower viewing angle (35°). The Diffused lens distributes light more broadly (40° viewing angle) with lower peak brightness (25mcd). Selection depends on application requirements for brightness concentration versus viewing angle distribution.

Q: Does the viewing angle difference affect compatibility?

A: The viewing angle increase from 35° to 40° expands the observable light distribution. This is generally compatible with panel indicator applications. Verify that the broader viewing angle meets specific application requirements for observer positioning and visibility.

Q: Are there packaging differences between these components?

A: The MPR5ATW12.0 is listed with "-" packaging notation, while the MPR5ADW12.0 is supplied in Bag packaging. Both components are identical in form factor and electrical specifications; packaging difference reflects current inventory configuration only.

Q: Is the MPR5ADW12.0 RoHS compliant?

A: Yes. The MPR5ADW12.0 is RoHS3 compliant. The original MPR5ATW12.0 RoHS status is not specified in available documentation.

Q: What is the inventory status for these components?

A: The MPR5ATW12.0 (obsolete) has 816 pieces in stock. The MPR5ADW12.0 (active) has 1085 pieces in stock. For new designs, the active MPR5ADW12.0 is recommended to ensure long-term supply continuity.

Q: Are there any electrical parameter differences that require circuit redesign?

A: No. Both components operate at identical voltage (2V) and current (30mA) specifications. Existing current-limiting resistor values and power supply configurations require no modification.
