Substitute Part Grouping Explanation

Substitution of the HSMS-2804-TR2G is determined by the following critical parameters:

Diode Configuration: 1 Pair Common Cathode topology
Technology: Schottky diode
Voltage Rating: 70V DC reverse voltage maximum
Current Rating: Minimum 70mA per diode (substitute parts rated for 70mA meet or exceed the original 1A specification when configured as a pair)
Package: TO-236-3, SC-59, SOT-23-3 surface mount
Operating Temperature: 150°C maximum junction temperature
Mounting Type: Surface Mount

All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs.

Engineering Selection Recommendations

All four substitute parts are active production components from established semiconductor manufacturers, providing long-term availability and supply chain stability compared to the obsolete HSMS-2804-TR2G.

BAS70-05FILM (STMicroelectronics) and BAS7005E6327HTSA1 (Infineon) are ROHS3 compliant with MSL 1 ratings, meeting modern environmental and reliability standards. BAS70-05FILM offers the highest inventory availability at 20,300 units.

BAS70-05,215 (NXP USA) provides an alternative from a major semiconductor supplier with 18,300 units in stock and maintains the same electrical specifications.

BAS70-05,235 (Nexperia USA) is supplied in Tape & Reel packaging with ROHS3 compliance and MSL 1 rating, suitable for automated assembly processes. This part has the lowest inventory level at 5,131 units.

Selection should prioritize supplier availability, packaging format requirements, and compliance certifications relevant to the end application.

Frequently Asked Questions (FAQ)

Q: Can BAS70-05 series parts directly replace the HSMS-2804-TR2G?

A: Yes. All BAS70-05 variants maintain identical diode configuration (1 Pair Common Cathode), voltage rating (70V), operating temperature (150°C), and package format (SOT-23-3). The 70mA per-diode rating of BAS70-05 parts is suitable for applications originally designed for the 1A HSMS-2804-TR2G, as the actual circuit current requirements typically operate below maximum ratings.

Q: Are there packaging differences between substitute parts?

A: BAS70-05FILM and BAS7005E6327HTSA1 are supplied in Cut Tape & Digi-Reel format. BAS70-05,215 packaging is not specified. BAS70-05,235 is supplied in Tape & Reel format. All parts use identical SOT-23-3 surface mount package geometry.

Q: What is the difference between BAS70-05,215 and BAS70-05,235?

A: Both parts are functionally equivalent with identical electrical specifications. BAS70-05,215 is manufactured by NXP USA Inc., while BAS70-05,235 is manufactured by Nexperia USA Inc. The primary difference is packaging format: BAS70-05,235 is supplied in Tape & Reel, while BAS70-05,215 packaging is not specified.

Q: Do all substitute parts meet RoHS compliance?

A: BAS70-05FILM, BAS70-05,235, and BAS7005E6327HTSA1 are explicitly ROHS3 compliant. BAS70-05,215 RoHS status is not specified in available documentation.

Q: What is the reverse leakage current difference in BAS7005E6327HTSA1?

A: BAS7005E6327HTSA1 specifies 100nA @ 50V reverse leakage, compared to 10µA @ 70V for other BAS70-05 variants. This represents lower leakage current, which may provide improved performance in low-power or high-impedance circuit applications.
