Key Parameters

Substitute Part Grouping Explanation

Substitution of the WP934RT/2GD with the WP934EB/2GD is based on the following allowed parameter variations:

Electrical Parameters (Allowed Variance):

• Voltage Rating: 2V to 2.2V (within acceptable LED forward voltage tolerance)
• Current Rating: 25mA to 20mA (reduced current operation acceptable for indicator applications)
• Millicandela Rating: 25mcd to 22.5mcd (brightness variance within indicator specification range)

Optical Parameters (Allowed Variance):

• Wavelength - Peak: 568nm to 565nm (within green spectrum tolerance for visual indication)
• Viewing Angle: 40° (maintained)
• Lens Type: Diffused, Tinted (maintained)
• Lens Style: Round with Domed Top (maintained)

Mechanical Parameters (Allowed Variance):

• Lens Size: 2.90mm Dia to 3mm, T-1 (standard LED form factor variation)
• Mounting Type: Through Hole, Right Angle (maintained)

Compliance Parameters (Maintained):

• RoHS Status: ROHS3 Compliant (both parts)
• MSL Rating: 1 (Unlimited) (both parts)
• REACH Status: REACH Unaffected (both parts)

Both parts share the same base product number (WP934) and configuration (2 High), confirming functional equivalence within the allowed parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (WP934RT/2GD):

• Use when 2.90mm lens diameter is specified in circuit board layout
• Use when 25mA current budget is available in the design
• Use when 2V nominal forward voltage is required
• Product status: Active with 825 Pcs inventory available

Substitute Part Selection (WP934EB/2GD):

• Use when 3mm, T-1 lens diameter accommodates board layout requirements
• Use when reduced current operation (20mA) is acceptable
• Use when 2.2V forward voltage is compatible with circuit design
• Product status: Active with 7296 Pcs inventory available
• Packaging: Bulk format

Both parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can WP934EB/2GD replace WP934RT/2GD in all applications?

A: Substitution is valid when the circuit design accommodates the parameter differences: 3mm lens diameter (versus 2.90mm), 20mA current operation (versus 25mA), and 2.2V forward voltage (versus 2V). Board layout and current limiting resistor values must be verified for the substitute part.

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

A: The main differences are lens size (2.90mm versus 3mm T-1 form factor), current rating (25mA versus 20mA), and forward voltage (2V versus 2.2V). All other electrical, optical, and mechanical parameters remain within tolerance.

Q: Are both parts RoHS compliant?

A: Yes, both WP934RT/2GD and WP934EB/2GD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does the "2 High" configuration mean?

A: The "2 High" configuration indicates a dual-level LED assembly with two green LEDs stacked vertically within a single package, providing dual-color or dual-intensity indication capability.

Q: Does lens size affect optical performance?

A: Both parts maintain identical viewing angle (40°), lens type (diffused, tinted), and lens style (round with domed top). The 3mm T-1 form factor of the substitute is a standard LED package variation that does not affect optical performance within the specified 40° viewing angle.

Q: What packaging format is available for each part?

A: WP934RT/2GD is available in standard packaging with 825 Pcs inventory. WP934EB/2GD is available in bulk packaging with 7296 Pcs inventory.

Q: Can I use WP934EB/2GD if my design requires exactly 25mA?

A: The substitute part is rated for 20mA operation. If the design requires 25mA, the primary part WP934RT/2GD must be used to meet the current specification.
