SH8K3TB1 Equivalent & Substitute Parts Reference Page

Part Overview

The Rohm Semiconductor SH8K3TB1 is a MOSFET array featuring two N-channel MOSFETs in a surface-mount 8-SOP package. Key characteristics include a maximum drain-to-source voltage (Vdss) of 30V, continuous drain current (Id) up to 7A (Ta), Rds(on) of 24mOhm at 7A, and a maximum power dissipation of 2W (Ta). The device is RoHS3 compliant, REACH unaffected, and supplied in tape & reel packaging. This part is designated as Not For New Designs, indicating that alternative or substitute models are required for continued design-in and production use.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by direct equivalence or improvement in key electrical and mechanical parameters for dual N-channel MOSFETs in the same package category. Substitutes are grouped based on matching or exceeding drain-to-source voltage, continuous drain current, Rds(on), threshold voltage (Vgs(th)), gate charge, input capacitance, maximum power, package compatibility, and compliance status. Only parts meeting or surpassing these parameters within the same surface-mount 8-SOIC/8-SOP package are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

When selecting a substitute for SH8K3TB1, verify that the alternative part maintains comparable or better RoHS3 compliance, REACH status, and Moisture Sensitivity Level (MSL 1). FDS8984 (onsemi) is listed as an active product with equivalent compliance and package type, while SH8KA2GZETB (Rohm Semiconductor) is also RoHS3 compliant but identified as Not For New Designs.

Frequently Asked Questions (FAQ)

Q1: What determines if a MOSFET is a suitable substitute for SH8K3TB1?
A: Substitutes must match key electrical parameters (Vdss, Id, Rds(on), Vgs(th)), configuration (dual N-channel), mechanical characteristics (surface mount, 8-SOIC/8-SOP), and compliance attributes (RoHS3, REACH, MSL 1).

Q2: Is package compatibility important for substitution?
A: Yes. All substitutes listed use an 8-SOIC (0.154", 3.90mm Width) or 8-SOP package, ensuring mechanical and footprint compatibility.

Q3: Can I substitute with a part marked as Not For New Designs?
A: Substitution is technically feasible, but for new designs, select parts with an active status to ensure long-term availability.

Q4: How do compliance certifications affect substitute selection?
A: Only parts with ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) are specified as eligible substitutes per the provided data.

Q5: Are all electrical parameters required to match exactly?
A: All listed substitutes meet or exceed the main functional parameters. Exact matches are not always present, but substitutions are chosen strictly within allowed parameter margins provided.
