RB715WMFHTL Equivalent & Substitute Parts

Part Overview

The RB715WMFHTL is a Schottky diode array manufactured by Rohm Semiconductor, configured as 1 pair series connection with a maximum reverse voltage rating of 40 V and average rectified current of 30 mA per diode. The device is housed in a surface mount SC-89 (SOT-490) package and is qualified to AEC-Q101 automotive standards. This part is currently in active production status. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or packaging format changes while maintaining full functional compatibility.

Substitute Part Grouping Explanation

Substitute parts for the RB715WMFHTL are identified based on strict equivalence of the following electrical and mechanical parameters:

• Diode configuration: 1 pair series connection
• Technology: Schottky
• Maximum reverse voltage: 40 V
• Average rectified current per diode: 30 mA
• Forward voltage: 370 mV @ 1 mA
• Speed classification: Small signal ≤ 200mA
• Package / case: SC-89, SOT-490
• Mounting type: Surface mount
• Supplier device package: EMD3F
• RoHS compliance: ROHS3 compliant
• Automotive grade qualification: AEC-Q101

The RB706WM-40FHTL and RB706WM-40TL meet all electrical specifications and mechanical requirements for direct substitution. Differences in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product status do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

RB706WM-40TL is the primary substitute for the RB715WMFHTL. Both parts share identical electrical specifications, automotive qualification (AEC-Q101), and active product status. The RB706WM-40TL is supplied in Tape & Reel packaging, matching the format of the main part. This part is suitable for new designs and ongoing production applications.

RB706WM-40FHTL is a secondary substitute available in Cut Tape & Digi-Reel® packaging format. This part carries a "Not For New Designs" status and exhibits improved moisture sensitivity characteristics (MSL 1 versus MSL 3). The RB706WM-40FHTL is appropriate for replacement or repair applications where the alternative packaging format is acceptable and inventory availability is a consideration.

Both substitute parts maintain full electrical and mechanical compatibility with the RB715WMFHTL across all critical parameters including reverse voltage, forward voltage, current rating, temperature range, and automotive qualification standards.

Frequently Asked Questions (FAQ)

Q: Can RB706WM-40TL be used as a direct replacement for RB715WMFHTL in production?

A: Yes. The RB706WM-40TL meets all electrical and mechanical specifications required for direct substitution. Both parts are rated for 40 V reverse voltage, 30 mA average rectified current, and carry AEC-Q101 automotive qualification. The RB706WM-40TL is in active product status and suitable for new designs.

Q: What is the difference between RB706WM-40FHTL and RB706WM-40TL?

A: The primary differences are packaging format and product status. RB706WM-40FHTL is supplied in Cut Tape & Digi-Reel® format with MSL 1 rating, while RB706WM-40TL is supplied in Tape & Reel format with MSL 1 rating. RB706WM-40TL maintains active product status, whereas RB706WM-40FHTL is designated "Not For New Designs." Electrical specifications are identical.

Q: Are there any electrical performance differences between the main part and substitutes?

A: All three parts share identical electrical specifications: 40 V maximum reverse voltage, 30 mA average rectified current per diode, 370 mV forward voltage at 1 mA, and 125°C maximum junction temperature. Reverse leakage current differs slightly (1 µA @ 10 V for RB715WMFHTL versus 500 nA @ 30 V for RB706 variants), but this does not affect functional compatibility in circuit applications.

Q: Can RB706WM-40FHTL be used in new designs?

A: RB706WM-40FHTL carries a "Not For New Designs" designation. For new design applications, RB706WM-40TL or RB715WMFHTL are the appropriate selections. RB706WM-40FHTL is suitable for replacement, repair, or legacy system applications.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: No. RB715WMFHTL has MSL 3 (168 hours), while both RB706WM-40FHTL and RB706WM-40TL have MSL 1 (unlimited). MSL 1 parts have superior moisture resistance and do not require time-limited storage conditions. This difference does not affect electrical performance but may influence handling and storage procedures.

Q: Are all parts compliant with automotive standards?

A: Yes. All three parts are automotive grade and qualified to AEC-Q101 standards. All are ROHS3 compliant and REACH unaffected. All carry the same ECCN (EAR99) and HTSUS (8541.10.0070) classifications.

Q: What packaging formats are available?

A: RB715WMFHTL and RB706WM-40TL are supplied in Tape & Reel (TR) format. RB706WM-40FHTL is supplied in Cut Tape (CT) & Digi-Reel® format. All three parts use the same EMD3F supplier device package and SC-89 (SOT-490) case outline.
