Equivalent & Substitute Parts for WP934RS/YD

Part Overview

The WP934RS/YD is a circuit board indicator LED manufactured by Kingbright, designed for through-hole, right-angle mounting applications. This single yellow diffused LED operates at 2.1V with a 30mA current rating and delivers 15 millicandela brightness at a 590nm peak wavelength. The component features a 3mm T-1 round domed lens with a 40° viewing angle, suitable for panel-mounted indicator applications requiring yellow illumination.

The WP934RS/YD maintains Active product status and carries ROHS3 compliance certification. Identifying equivalent substitute parts is necessary when the primary part number becomes unavailable, when bulk packaging alternatives are required, or when inventory constraints necessitate sourcing from alternative stock positions.

Electrical Parameters (Must Match Exactly):

• Voltage Rating: 2.1V
• Current: 30mA
• Millicandela Rating: 15mcd
• Wavelength - Peak: 590nm
• Color: Yellow

Mechanical Parameters (Must Match Exactly):

• Lens Size: 3mm, T-1
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Viewing Angle: 40°
• Mounting Type: Through Hole, Right Angle
• Configuration: Single

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The WP934RS/YD and its substitute share the same base product number (WP934), confirming they are part of the same product family with identical electrical and optical specifications. Differences exist only in packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The WP934EW/YD is a direct electrical and mechanical equivalent to the WP934RS/YD. Both components are manufactured by Kingbright, share identical electrical specifications (2.1V, 30mA, 15mcd), and feature the same optical characteristics (590nm yellow, 40° viewing angle, diffused tinted lens). Both maintain Active product status and carry ROHS3 compliance certification.

The primary distinction between these parts is packaging configuration. The WP934EW/YD is supplied in bulk packaging, whereas the WP934RS/YD packaging specification is not detailed in the provided data. This packaging difference does not affect electrical performance, mechanical fit, or circuit functionality.

Selection between these parts should be based on:

1. Inventory Availability: The WP934EW/YD currently has 1206 pieces in stock compared to 867 pieces for the WP934RS/YD.

2. Packaging Requirements: If bulk packaging is acceptable for your procurement and assembly processes, the WP934EW/YD is suitable.

3. Regulatory Compliance: Both parts satisfy ROHS3 compliance and REACH unaffected status, making either part acceptable for regulated applications.

4. Circuit Compatibility: No circuit modifications are required when substituting between these parts, as all electrical parameters are identical.
