LED CBI A02PE - Equivalent & Substitute Parts

Part Overview

The NKK Switches A02PE is a 3mm through-hole LED circuit board indicator with yellow emission. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production, maintenance, and repair applications. The A02PE delivers 30mA at 2.1V nominal operating conditions in a standard T-1 form factor with domed lens geometry.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A02PE is determined by the following critical parameters:

• Color: Yellow emission required
• Configuration: Single LED element
• Mounting Type: Through hole connection
• Lens Form Factor: 3mm T-1 standard package geometry
• Electrical Compatibility: Forward voltage and current ratings within acceptable operating margins for circuit integration

The A01PE qualifies as a substitute based on matching color, configuration, mounting type, and form factor. Electrical parameter variations (voltage 2.2V vs. 2.1V; current 50mA vs. 30mA) remain within typical design tolerances for LED circuit board indicator applications where the component operates in current-limited circuits.

Parameter Comparison

Engineering Selection Recommendations

The A01PE serves as the primary substitute for the obsolete A02PE. Selection is justified on the following basis:

• Product Status: A01PE maintains active production status, ensuring availability and supply chain continuity
• Regulatory Compliance: A01PE carries ROHS3 compliance and REACH unaffected designation, meeting current environmental and safety standards
• Functional Equivalence: Both components share identical color, configuration, and mounting characteristics essential for circuit board indicator applications
• Electrical Parameters: The A01PE operates at 2.2V and 50mA, representing minor increases from the A02PE specification. These variations are accommodated within standard LED circuit design practices using series current-limiting resistors

Frequently Asked Questions (FAQ)

Q: Can the A01PE directly replace the A02PE without circuit modification?

A: The A01PE is electrically compatible with circuits designed for the A02PE. Both components operate as single yellow through-hole LEDs with identical mounting geometry. Existing current-limiting resistor values remain valid, as the voltage and current differences fall within normal design margins for indicator applications.

Q: What is the significance of the lens style difference between parts?

A: The A02PE specifies a round domed top lens at 3mm T-1 form factor. The A01PE does not specify lens style in the provided data. Verify lens geometry with the manufacturer if optical characteristics are critical to the application.

Q: Why is the A02PE classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The A01PE, as an active product from the same manufacturer, represents the current production equivalent for this LED indicator category.

Q: Are there compliance differences between the two parts?

A: The A01PE includes ROHS3 compliance and REACH unaffected certification. The A02PE data does not specify these certifications. For applications requiring regulatory compliance documentation, the A01PE provides explicit compliance statements.

Q: How should I handle existing A02PE inventory?

A: The A02PE remains available in stock (787 units). Existing inventory can continue to be used in current production. Transition to A01PE for new designs and long-term production planning to ensure supply continuity.
