WP3DPD1C Equivalent & Substitute Parts

Part Overview

The WP3DPD1C is an infrared photodiode sensor manufactured by Kingbright, designed for 940nm wavelength detection applications. This component is classified as a PIN photodiode with radial through-hole mounting and is currently in active product status. The WP3DPD1C serves as the primary reference part for applications requiring near-infrared photodetection with 6 nanosecond response time and 50-degree viewing angle specifications. Substitute parts are identified to address inventory availability, packaging format requirements, or procurement lead time considerations while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the WP3DPD1C is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Wavelength: 940nm
• Diode Type: PIN
• Response Time: 6ns
• Voltage - DC Reverse (Vr) Max: 170V
• Current - Dark (Typ): 10nA
• Viewing Angle: 50°
• Operating Temperature Range: -40°C to 85°C
• Mounting Type: Through Hole
• Package / Case: Radial
• Base Product Number: WP3DPD1

The WP3DPD1BT/BD variant meets all primary equivalence criteria and is classified as a manufacturer-recommended substitute. The primary distinction between WP3DPD1C and WP3DPD1BT/BD is packaging format: WP3DPD1C is supplied in standard packaging, while WP3DPD1BT/BD is supplied in bulk packaging. Both parts share identical electrical specifications, mechanical dimensions, and performance characteristics.

Engineering Selection Recommendations

WP3DPD1C Primary Selection: The WP3DPD1C is the standard configuration for this photodiode sensor. Both WP3DPD1C and WP3DPD1BT/BD maintain active product status with full compliance to ROHS3 and REACH regulations. Selection between these parts should be based on packaging and procurement requirements rather than electrical performance, as all specified parameters are identical.

WP3DPD1BT/BD Substitute Selection: The WP3DPD1BT/BD is the manufacturer-recommended substitute, supplied in bulk packaging format. This variant is appropriate for high-volume production environments or applications where bulk packaging reduces material handling costs. Electrical and mechanical specifications are fully equivalent to WP3DPD1C.

Compliance Considerations: Both parts carry identical regulatory certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 export classification. No compliance trade-offs exist between the primary part and substitute.

Frequently Asked Questions (FAQ)

Q: Can WP3DPD1BT/BD be used as a direct replacement for WP3DPD1C in circuit design?
