Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OP800WSL are qualified based on the following critical parameters that determine functional compatibility:

Mechanical Compatibility:

• Package / Case: TO-206AA, TO-18-3 Metal Can (identical)
• Mounting Type: Through Hole (identical)
• Orientation: Top View (identical)

Electrical Compatibility:

• Collector Emitter Breakdown Voltage: Substitute parts must meet or exceed 30 V maximum
• Collector Current (Ic) Maximum: 50 mA (identical across all parts)
• Dark Current (Id) Maximum: 100 nA (identical across all parts)
• Power Dissipation: 250 mW maximum (identical across all parts)

Spectral Compatibility:

• Wavelength sensitivity range: 450nm to 1080nm (encompasses 890nm operation)

Regulatory & Environmental:

• RoHS3 Compliance: Required
• Operating Temperature Range: Must support applications within -65°C to 125°C envelope
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The substitute parts BPW76A and BPW76B from Vishay Semiconductor Opto Division meet all mechanical and electrical compatibility criteria. Both parts feature identical maximum ratings for collector current and dark current, support the same power dissipation, and are housed in the identical TO-206AA package. The wavelength sensitivity range of 450nm to 1080nm encompasses the 890nm operation of the OP800WSL.

Parameter Comparison

Engineering Selection Recommendations

Both BPW76A and BPW76B are qualified substitutes for the OP800WSL based on identical mechanical packaging, matching electrical current and power ratings, and full RoHS3 compliance. All three parts maintain MSL 1 (Unlimited) moisture sensitivity classification, eliminating moisture-related handling constraints.

The substitute parts feature higher collector-emitter breakdown voltage ratings (70 V versus 30 V), providing enhanced voltage margin in circuit designs. The wavelength sensitivity range of 450nm to 1080nm for BPW76A and BPW76B encompasses the 890nm peak sensitivity of the OP800WSL, ensuring functional compatibility in infrared detection circuits.

Operating temperature range differs between the main part and substitutes. The OP800WSL supports -65°C to 125°C, while BPW76A and BPW76B support -40°C to 125°C. Applications requiring operation below -40°C must retain the OP800WSL. For applications within the -40°C to 125°C range, both substitute parts are electrically and mechanically equivalent.

All three parts are in active production status with current inventory availability, supporting uninterrupted supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can BPW76A and BPW76B be used interchangeably with OP800WSL in existing designs?

A: BPW76A and BPW76B are mechanically and electrically compatible substitutes for applications operating within the -40°C to 125°C temperature range. Both parts share identical TO-206AA packaging, collector current ratings (50 mA maximum), dark current specifications (100 nA maximum), and power dissipation limits (250 mW). The wavelength sensitivity range of 450nm to 1080nm encompasses 890nm operation. Applications requiring operation below -40°C must use the OP800WSL.

Q: What are the key differences between OP800WSL and the substitute parts?

A: The primary differences are: (1) Collector-emitter breakdown voltage: OP800WSL is rated at 30 V maximum, while BPW76A and BPW76B are rated at 70 V maximum; (2) Operating temperature minimum: OP800WSL operates to -65°C, while substitutes operate to -40°C minimum; (3) Wavelength specification: OP800WSL is specified at 890nm peak, while substitutes specify a 450nm to 1080nm range. All other electrical and mechanical parameters are identical.

Q: Are BPW76A and BPW76B identical to each other?

A: BPW76A and BPW76B are electrically and mechanically identical. Both are manufactured by Vishay Semiconductor Opto Division, share the same TO-206AA package, and have identical electrical ratings and operating specifications. Selection between these two parts is based on inventory availability and supply chain considerations.

Q: What packaging and mounting considerations apply to these phototransistors?

A: All three parts (OP800WSL, BPW76A, BPW76B) use identical TO-206AA, TO-18-3 metal can packaging with through-hole mounting and top-view orientation. PCB layout, lead spacing, and mounting procedures are identical across all three parts. No design modifications are required when substituting between these parts.

Q: Are all three parts RoHS3 compliant?

A: Yes. OP800WSL, BPW76A, and BPW76B are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification. All parts meet REACH unaffected status and carry EAR99 ECCN classification.
