Substitute Part Grouping Explanation

Substitution of the B160B-13 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 60V minimum
Current - Average Rectified (Io): 1A minimum
Technology: Schottky
Mounting Type: Surface Mount
Package / Case: DO-214AA, SMB (or compatible surface mount package)
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitution Categories:

Parametric Equivalents maintain identical electrical specifications and packaging. These parts are direct replacements with no circuit redesign required.

Direct Manufacturer Equivalents are from alternative manufacturers but meet all core electrical and mechanical parameters.

Manufacturer Recommended Substitutes exceed the minimum specifications (higher current ratings or improved performance characteristics) and are suitable for applications where the B160B-13 was specified, provided the circuit design accommodates the enhanced ratings.

Parts with higher current ratings (3A) remain valid substitutes for 1A applications due to backward compatibility in Schottky diode design, where higher-rated devices operate within the same voltage and thermal envelope.

Engineering Selection Recommendations

Tier 1 - Direct Parametric Equivalents (Recommended for Direct Replacement):

B160B-13-F and B160BQ-13-F from Diodes Incorporated are parametric equivalents with identical electrical specifications. Both are active products with ROHS3 compliance. B160BQ-13-F includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability. These parts require no circuit modification and maintain full compatibility with existing designs.

Tier 2 - Equivalent Performance from Alternative Manufacturers:

CMSH1-60 TR13 PBFREE (Central Semiconductor Corp) and CDBB160-G (Comchip Technology) meet all core electrical and mechanical requirements. STPS160U (STMicroelectronics) provides equivalent 1A performance with superior reverse leakage characteristics (4 µA versus 500 µA), beneficial for low-power applications. All three are active products with ROHS3 compliance.

Tier 3 - Higher Current Rating Substitutes:

SK36B-LTP (Micro Commercial Co), STPS3L60U, and STPS3L60UY (STMicroelectronics) are rated for 3A operation. These parts are suitable for applications where the B160B-13 was specified, as they maintain the same 60V reverse voltage rating and SMB package footprint. STPS3L60UY includes AEC-Q101 automotive qualification. Higher current ratings provide design margin for thermal and reliability considerations.

Package Consideration:

PMEG6010EP,115 (Nexperia USA Inc.) uses SOD-128 packaging instead of SMB. This part is electrically equivalent but requires PCB layout modification. Forward voltage is reduced to 530 mV at 1A, and reverse leakage is significantly lower at 60 µA, offering improved efficiency in switching applications.

Compliance Status:

All substitute parts are ROHS3 compliant and REACH unaffected. The original B160B-13 is RoHS non-compliant; substitution with any listed alternative ensures regulatory compliance for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can B160B-13-F be used as a direct replacement for B160B-13?

A: Yes. B160B-13-F is a parametric equivalent with identical electrical specifications (60V, 1A, 700 mV forward voltage). The primary difference is product status (active versus discontinued) and RoHS compliance (ROHS3 compliant). No circuit modification is required.

Q: What is the difference between B160BQ-13-F and B160B-13-F?

A: Both are parametric equivalents from Diodes Incorporated with identical electrical ratings. B160BQ-13-F includes AEC-Q101 automotive qualification, making it suitable for automotive applications requiring enhanced reliability and qualification documentation.

Q: Can 3A-rated diodes (SK36B-LTP, STPS3L60U, STPS3L60UY) replace the 1A B160B-13?

A: Yes. Higher current-rated Schottky diodes are backward compatible with lower current applications. The 3A parts operate within the same voltage envelope and package footprint. This substitution provides additional thermal margin and design headroom. Circuit performance remains unchanged for 1A operation.

Q: Why does PMEG6010EP,115 have lower forward voltage (530 mV) compared to B160B-13 (700 mV)?

A: PMEG6010EP,115 uses SOD-128 packaging and represents a different die design from Nexperia. Lower forward voltage indicates improved efficiency but requires PCB layout modification due to different package geometry. This part is suitable only if PCB redesign is acceptable.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage varies across manufacturers and designs. STPS160U exhibits 4 µA leakage versus 500 µA for B160B-13. Lower leakage reduces standby power consumption and heat generation in low-current applications. Higher leakage (500 µA) is acceptable for most switching applications and does not affect forward conduction performance.

Q: Is CMSH1-60 TR13 PBFREE suitable for high-frequency switching?

A: Yes. CMSH1-60 TR13 PBFREE meets the fast recovery specification (≤ 500ns, > 200mA) identical to B160B-13. The "PBFREE" designation indicates lead-free construction, compliant with RoHS requirements. Performance in high-frequency applications is equivalent to the original part.

Q: Can I use STPS3L60UY in place of B160B-13 in automotive applications?

A: Yes. STPS3L60UY is rated for 3A at 60V with AEC-Q101 automotive qualification. It exceeds the 1A requirement of B160B-13 and is suitable for automotive designs. The higher current rating provides additional design margin without affecting circuit operation at 1A.

Q: What packaging considerations apply when substituting PMEG6010EP,115?

A: PMEG6010EP,115 uses SOD-128 (CFP5) packaging instead of SMB (DO-214AA). PCB footprint, solder pad geometry, and component placement differ significantly. Schematic compatibility is maintained, but PCB layout redesign is required. This substitution is suitable only when PCB modification is feasible.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original B160B-13 is RoHS non-compliant. Substitution with any alternative ensures compliance with current environmental and regulatory standards.

Q: Which substitute offers the best performance for low-power applications?

A: STPS160U provides the lowest reverse leakage current (4 µA at 60V) among 1A-rated equivalents, reducing standby power consumption. PMEG6010EP,115 offers the lowest forward voltage (530 mV at 1A), improving efficiency during conduction. Selection depends on whether leakage or forward voltage is the primary design constraint.
