Substitute Part Grouping Explanation

Substitution of the RB706UM-40FHTL is determined by strict equivalence across the following critical parameters:

• Diode Configuration: 1 Pair Series Connection
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 30 mA
• Voltage - Forward (Vf) (Max) @ If: 370 mV @ 1 mA
• Current - Reverse Leakage @ Vr: 1 µA @ 30 V
• Operating Temperature - Junction (Max): 125°C
• Package / Case: SC-85
• Supplier Device Package: UMD3F
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The RB706UM-40TL qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications and mechanical packaging. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) & Digi-Reel® format. The substitute part maintains active product status, providing design continuity for applications requiring the RB706 base product series.

Parameter Comparison

Engineering Selection Recommendations

The RB706UM-40TL is a direct parametric equivalent to the RB706UM-40FHTL. All electrical characteristics, mechanical dimensions, and compliance certifications are identical. The substitute part is manufactured by the same supplier (Rohm Semiconductor) and carries active product status, ensuring continued availability and support.

Selection of the RB706UM-40TL is appropriate for applications currently using the RB706UM-40FHTL. The difference in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) does not affect electrical performance or PCB assembly compatibility. Both parts meet ROHS3 compliance and REACH requirements, maintaining regulatory alignment for automotive and industrial applications.

For new designs, the RB706UM-40TL is the recommended choice due to its active product status, providing long-term supply chain stability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the RB706UM-40TL be used as a direct replacement for the RB706UM-40FHTL?

A: Yes. The RB706UM-40TL is a parametric equivalent with identical electrical specifications, forward voltage characteristics, reverse leakage current, and thermal ratings. Both parts use the same SC-85 surface mount package and UMD3F supplier device package, ensuring mechanical and electrical compatibility.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) is a continuous reel format for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides flexibility for lower-volume orders and mixed component picking. Both formats contain the same component in the same package; the difference is in supply and handling format only.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the RB706UM-40FHTL and RB706UM-40TL are ROHS3 compliant, REACH unaffected, and carry identical electrical ratings. Both support automotive-grade applications with AEC-Q101 qualification (main part) and equivalent reliability standards.

Q: Why is the RB706UM-40FHTL marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Rohm Semiconductor has transitioned this part to end-of-life status. The RB706UM-40TL, with active product status, is the recommended alternative for new designs and ongoing production.

Q: Will switching to the RB706UM-40TL require PCB layout changes?

A: No. Both parts use the same SC-85 surface mount package with identical pin configuration and footprint. No PCB redesign is necessary.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating they have unlimited shelf life and require no special moisture control during storage or handling.
