Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

BAS116E6327HTSA1 (Infineon Technologies) is a parametric equivalent with identical electrical specifications and package form factor. This part is available in Cut Tape packaging with 2049 units in stock. Both the main part and this equivalent share Last Time Buy status, indicating both are discontinued. Selection between these two should be based on packaging availability (Tape & Reel versus Cut Tape) and inventory requirements.

Active Production Alternatives (Recommended for New Designs):

MMBD4448H-7-F (Diodes Incorporated) meets or exceeds all primary substitution criteria with 80 V reverse voltage and 250 mA current rating. This part is in Active product status with 32,400 units in stock. It features improved reverse recovery time (4 ns versus 1.5 µs) and is suitable for applications where faster switching performance is beneficial or neutral.

BAS116-7-F (Diodes Incorporated) provides 85 V reverse voltage with 215 mA current rating in Active status. This part exceeds the voltage requirement and is available with 155,300 units in stock, offering superior supply chain security.

Functional Substitutes (Application-Dependent):

BAS116,215 and BAS116,235 (Nexperia USA Inc.) are functionally equivalent with 75 V reverse voltage and 215 mA current rating. These parts are qualified to AEC-Q100 automotive standard and are in Active status. Selection is appropriate for applications where the reduced voltage and current ratings remain within design margins.

SBAS116LT1G (onsemi) and BAS116-TP (Micro Commercial Co) provide 75 V reverse voltage with 200 mA current rating. Both are in Active status and suitable for applications with reduced current requirements.

PMBD6050,215 and PMBD6050,235 (NXP Semiconductors and Nexperia USA Inc.) feature 70 V reverse voltage with 215 mA current rating and fast recovery characteristics (4 ns). These parts are appropriate for applications where lower voltage ratings are acceptable and faster switching is required.

Frequently Asked Questions (FAQ)

Q: Can BAS116E6327HTSA1 be used as a direct replacement for BAS116E6433HTMA1?

A: Yes. BAS116E6327HTSA1 is a parametric equivalent with identical electrical specifications (80 V, 250 mA, 1.25 V forward voltage, 1.5 µs recovery time) and package form factor (SOT-23-3). The only difference is packaging format: BAS116E6433HTMA1 is supplied in Tape & Reel, while BAS116E6327HTSA1 is supplied in Cut Tape. Both parts are Last Time Buy status.

Q: What is the difference between standard recovery and fast recovery diodes in this list?

A: Recovery time characterizes how quickly a diode transitions from conducting to blocking state. BAS116E6433HTMA1 has standard recovery (1.5 µs). MMBD4448-7-F, MMBD4448H-7-F, PMBD6050,215, and PMBD6050,235 have fast recovery (4 ns). Fast recovery diodes are beneficial in high-frequency switching applications but are not required for low-frequency rectification circuits.

Q: Can I use MMBD4448H-7-F as a substitute if my application requires exactly 80 V and 250 mA?

A: Yes. MMBD4448H-7-F meets both requirements with 80 V reverse voltage and 250 mA current rating. It is in Active production status with high inventory availability (32,400 units). The improved reverse recovery time (4 ns versus 1.5 µs) will not negatively impact circuit performance in standard rectification applications.

Q: Why do some substitute parts have lower voltage or current ratings?

A: Parts with reduced ratings (such as 75 V instead of 80 V, or 215 mA instead of 250 mA) are functional substitutes suitable only for applications where design margins accommodate the lower specifications. These parts should not be used in designs that operate at or near the original part's maximum ratings.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity level, matching the environmental compliance profile of BAS116E6433HTMA1.

Q: What is the significance of AEC-Q100 qualification on BAS116,215 and BAS116,235?

A: AEC-Q100 is an automotive industry qualification standard. Parts bearing this qualification have undergone additional reliability testing and are approved for automotive applications. This qualification does not affect general-purpose rectification performance but indicates suitability for automotive environments.

Q: Can I mix different substitute parts in the same production batch?

A: All substitute parts are mechanically and electrically compatible within the SOT-23-3 package form factor and maintain identical pin configurations. However, mixing parts with different electrical characteristics (such as different recovery times or leakage currents) in the same circuit may introduce performance variations. Consistency within a single design is recommended.

Q: Which substitute offers the best supply chain availability?

A: BAS116,235 (Nexperia USA Inc.) offers the highest inventory with 116,588 units in stock. BAS116-7-F (Diodes Incorporated) provides 155,300 units. Both are in Active production status, ensuring long-term availability compared to Last Time Buy alternatives.
