Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1PS301,115 are identified based on strict alignment of electrical and mechanical parameters within the allowed specifications for general-purpose diode arrays. The substitution logic is based on the following key parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 80 V
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 160 mA
• Package / Case: SC-70, SOT-323 or equivalent surface mount package
• RoHS Status: ROHS3 Compliant (mandatory match)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (mandatory match)

Substitute Parts Identified:

1. BAV23CLT1G (onsemi): Exceeds voltage and current specifications with 250 V reverse voltage and 400 mA average rectified current. Package is TO-236-3, SC-59, SOT-23-3 (surface mount equivalent). Meets RoHS3 and MSL requirements. Product Status: Active.

2. CMSD2838 TR PBFREE (Central Semiconductor Corp): Meets voltage specification at 75 V reverse voltage with 200 mA average rectified current. Package is SC-70, SOT-323 (exact match). Meets RoHS3 and MSL requirements. Product Status: Active.

Parameter Comparison

Engineering Selection Recommendations

1PS301,115 (Nexperia USA Inc.): Primary selection for applications requiring AEC-Q101 automotive qualification. Maintains Active product status with substantial inventory. Suitable for automotive-grade applications with 80 V reverse voltage and 160 mA current requirements.

BAV23CLT1G (onsemi): Suitable for applications requiring higher voltage margin (250 V) and higher current capacity (400 mA). Package footprint differs (SOT-23-3 versus SOT-323), requiring PCB layout verification. Fast recovery speed classification (150 ns trr) differs from the main part. Active product status with highest inventory availability. Does not carry automotive qualification.

CMSD2838 TR PBFREE (Central Semiconductor Corp): Suitable for applications with voltage and current specifications near or below the main part ratings (75 V, 200 mA). Identical package (SC-70, SOT-323) and matching reverse recovery time (4 ns) enable direct mechanical and electrical substitution. Active product status. Does not carry automotive qualification. Lower inventory availability.

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can BAV23CLT1G replace 1PS301,115 in automotive applications?

A: BAV23CLT1G does not carry AEC-Q101 automotive qualification. If automotive qualification is a design requirement, BAV23CLT1G is not suitable. For non-automotive applications, BAV23CLT1G provides higher voltage and current ratings with Active product status.

Q: What is the primary difference between CMSD2838 TR PBFREE and 1PS301,115?

A: Both parts share identical package (SC-70, SOT-323), matching forward voltage (1.2 V @ 100 mA), and identical reverse recovery time (4 ns). CMSD2838 TR PBFREE operates at slightly lower voltage (75 V versus 80 V) and higher current (200 mA versus 160 mA). The main part carries AEC-Q101 automotive qualification; CMSD2838 TR PBFREE does not.

Q: Are package differences between SOT-323 and SOT-23-3 significant for substitution?

A: Yes. SOT-323 (SC-70) and SOT-23-3 (SC-59, TO-236-3) are distinct surface mount packages with different footprints, pin spacing, and land patterns. PCB layout and component placement must be verified before substituting BAV23CLT1G for 1PS301,115.

Q: Which substitute part offers the closest electrical match to 1PS301,115?

A: CMSD2838 TR PBFREE provides the closest electrical match, with identical package, forward voltage, and reverse recovery time. Voltage and current ratings are within 6% and 25% of the main part specifications, respectively.

Q: Do all parts meet RoHS3 compliance?

A: Yes. 1PS301,115, BAV23CLT1G, and CMSD2838 TR PBFREE all maintain ROHS3 Compliant status and MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the inventory status for each part?

A: 1PS301,115: 39100 Pcs. BAV23CLT1G: 65200 Pcs. CMSD2838 TR PBFREE: 5169 Pcs. All parts are listed as New Original In Stock.

Q: Can I use a higher-rated substitute part in place of 1PS301,115?

A: Higher-rated parts (such as BAV23CLT1G with 250 V and 400 mA ratings) are electrically compatible for applications designed for 80 V and 160 mA operation. Circuit design and thermal management must account for any differences in forward voltage and reverse recovery time characteristics.
