BPW76B Equivalent & Substitute Parts

Part Overview

The BPW76B is an active phototransistor manufactured by Vishay Semiconductor Opto Division, designed for optical sensing applications across the 450 to 1080 nm wavelength range with peak sensitivity at 850 nm. This component operates in the Through Hole mounting configuration using the TO-206AA and TO-18-3 Metal Can package. The BPW76B maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications requiring reliable photoelectric detection.

Substitute parts become necessary when addressing supply chain constraints, inventory availability, or application-specific performance requirements within the defined electrical and mechanical parameter boundaries.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BPW76B is determined by strict alignment across the following critical parameters:

Package and Mounting Compatibility: All substitute parts must use the TO-206AA or TO-18-3 Metal Can package with Through Hole mounting and Top View orientation to ensure mechanical and electrical interface compatibility.

Electrical Performance Boundaries: Substitute parts must maintain maximum collector-emitter breakdown voltage of at least 30 V, maximum collector current of 50 mA, and maximum dark current of 100 nA. The BPW76B operates at 70 V breakdown; substitutes operating at lower voltages remain acceptable within application constraints.

Optical Characteristics: Substitute parts must operate within the near-infrared spectrum, specifically at wavelengths between 850 nm and 890 nm, ensuring functional equivalence for photoelectric detection applications.

Regulatory and Compliance Status: All substitute parts must maintain Active product status, ROHS3 compliance, and MSL rating of 1 (Unlimited) to meet industrial and commercial deployment requirements.

Environmental Operating Range: Substitute parts must support operating temperatures spanning at least -40°C to 125°C or broader ranges to maintain thermal compatibility.

The identified substitute parts—OP801WSL and OP802WSL from TT Electronics/Optek Technology—satisfy all substitution criteria within these defined boundaries.

Engineering Selection Recommendations

BPW76B Selection: Maintain use of the BPW76B when applications require the higher collector-emitter breakdown voltage of 70 V and when 850 nm wavelength sensitivity is specifically required. The BPW76B remains the primary component choice for designs operating within its specified parameters.

OP801WSL and OP802WSL Selection: Both OP801WSL and OP802WSL serve as functional equivalents when supply availability of the BPW76B is constrained. These substitutes operate at 890 nm wavelength with 30 V maximum breakdown voltage. Selection between OP801WSL and OP802WSL depends on inventory availability, as both components share identical electrical and thermal specifications. OP802WSL currently maintains higher inventory levels (12,923 units) compared to OP801WSL (1,821 units).

All three components maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can OP801WSL or OP802WSL directly replace BPW76B in existing designs?

A: Direct replacement is possible when the application operates at or below 30 V collector-emitter breakdown voltage. Applications designed for the BPW76B's 70 V rating require circuit redesign or voltage limiting measures before substitution.

Q: What is the wavelength difference between BPW76B and the substitute parts?

A: The BPW76B operates at 850 nm peak sensitivity, while OP801WSL and OP802WSL operate at 890 nm. Both wavelengths fall within the near-infrared spectrum and are suitable for general photoelectric detection applications. Applications requiring specific 850 nm sensitivity should retain the BPW76B.

Q: Are OP801WSL and OP802WSL interchangeable with each other?

A: Yes. OP801WSL and OP802WSL are electrically and mechanically identical. Selection between them is based solely on inventory availability and procurement lead times.

Q: Do the substitute parts support the same operating temperature range as BPW76B?

A: OP801WSL and OP802WSL support an extended operating temperature range of -65°C to 125°C, compared to BPW76B's -40°C to 125°C. This extended range provides additional thermal margin for demanding applications.

Q: Are all three components packaged identically?

A: Yes. BPW76B, OP801WSL, and OP802WSL all use the TO-206AA and TO-18-3 Metal Can package with Through Hole mounting and Top View orientation, ensuring mechanical compatibility on printed circuit boards.

Q: What compliance certifications apply to these components?

A: All three components maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and REACH Unaffected status, meeting regulatory requirements for industrial and commercial deployment.
