Frequently Asked Questions (FAQ)

Q: Can SS26HE3_A/H or SS26HE3_A/I be used as direct replacements for SS26-M3/5BT?

A: Yes. Both parts are parametric equivalents with identical voltage rating (60V), current rating (2A), forward voltage (700 mV @ 2A), and package configuration (DO-214AA SMB). The primary difference is automotive-grade designation and AEC-Q101 qualification on the SS26HE3 variants, which provides enhanced reliability documentation for automotive applications.

Q: What is the significance of the 400 µA versus 500 µA reverse leakage current difference?

A: The SS26-M3/5BT specifies 400 µA @ 60V reverse leakage, while B260-13-F, B260Q-13-F, and CMSH2-60 specify 500 µA @ 60V. This 100 µA difference represents a 25% increase in leakage current. For most rectifier applications, both specifications are functionally acceptable. Applications with stringent leakage requirements should prioritize the 400 µA specification.

Q: Are there packaging differences between substitute parts?

A: Yes. SS26-M3/5BT, SS26HE3_A/H, SS26HE3_A/I, B260Q-13-F, and CMSH2-60 are supplied in Tape & Reel (TR) packaging. B260-13-F is supplied in Cut Tape (CT) & Digi-Reel® packaging. All parts use the same DO-214AA (SMB) package footprint for PCB assembly.

Q: Which substitute part has the highest inventory availability?

A: SS26HE3_A/I from Vishay offers the highest inventory availability at 341,300 pcs, followed by SS26HE3_A/H at 224,950 pcs. Both are automotive-qualified alternatives with identical electrical specifications to the main part.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All identified substitute parts are ROHS3 compliant with Moisture Sensitivity Level (MSL) of 1 (Unlimited), matching the compliance profile of the SS26-M3/5BT.

Q: What is the difference between standard and automotive-grade variants?

A: Automotive-grade variants (SS26HE3_A/H, SS26HE3_A/I, B260Q-13-F) carry AEC-Q101 qualification, indicating compliance with automotive industry reliability and qualification standards. Standard-grade variants (SS26-M3/5BT, B260-13-F, CMSH2-60) do not carry this designation. Selection depends on application requirements and qualification documentation needs.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design accommodates the specified packaging format (Tape & Reel or Cut Tape). All substitute parts share identical DO-214AA (SMB) package footprint and electrical specifications within the defined tolerance ranges. PCB layout and assembly processes require no modification.
