The BAV74 from Fairchild Semiconductor meets all specified electrical and mechanical requirements and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The BAV74 from Fairchild Semiconductor is a direct parametric equivalent to the BAV74-TP from Micro Commercial Co. Both components are Active products with identical electrical specifications across all critical parameters: 50V reverse voltage rating, 200mA average rectified current, 1V forward voltage at 100mA, and 4ns reverse recovery time. Both components are housed in the identical TO-236-3 (SOT-23-3) Surface Mount package and operate across the same temperature range.

Both parts maintain REACH Unaffected status and comply with RoHS requirements. The Fairchild Semiconductor BAV74 offers significantly higher inventory availability (2,183,200 pieces) compared to the Micro Commercial Co BAV74-TP (1,526 pieces), making it suitable for high-volume production requirements or extended supply chain planning.

Selection between these two equivalent parts should be based on procurement lead times, cost structure, and supplier relationship considerations, as both components deliver identical functional performance in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the BAV74 from Fairchild Semiconductor be used as a direct replacement for the BAV74-TP from Micro Commercial Co?

A: Yes. Both components are parametric equivalents with identical electrical specifications, including 50V reverse voltage rating, 200mA average rectified current per diode, 1V forward voltage at 100mA, and 4ns reverse recovery time. Both are housed in the TO-236-3 (SOT-23-3) Surface Mount package and operate across compatible temperature ranges. No circuit modifications are required.

Q: Are there any package compatibility differences between these two parts?

A: No. Both the BAV74-TP and BAV74 use the identical TO-236-3, SC-59, SOT-23-3 Surface Mount package. Pin configuration, footprint, and mounting requirements are identical, allowing direct PCB-level substitution without layout changes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are REACH Unaffected and comply with RoHS requirements. Both maintain Active product status, ensuring continued availability and support from their respective manufacturers.

Q: What is the difference in operating temperature range between these parts?

A: The BAV74-TP specifies an operating junction temperature range of -55°C to 150°C. The BAV74 from Fairchild Semiconductor specifies a maximum junction temperature of 150°C. For applications requiring the full -55°C lower temperature limit, the BAV74-TP specification should be referenced. For standard commercial and industrial applications operating above -55°C, both parts are functionally equivalent.

Q: Which part should be selected for new designs?

A: Selection should be based on procurement availability, cost, and supplier lead times. Both parts deliver identical electrical and mechanical performance. The Fairchild Semiconductor BAV74 offers higher inventory availability, which may be advantageous for high-volume production or extended supply chain planning.

Q: Are these parts suitable for high-frequency switching applications?

A: Both components are classified as small signal diodes with 4ns reverse recovery time and are suitable for applications with switching frequencies up to the limits defined by the reverse recovery time specification. Specific application suitability should be determined by circuit design requirements and operating frequency.
