Engineering Selection Recommendations

Direct Electrical and Mechanical Equivalents (2 A, 30 V Rating):

The following parts meet all primary substitution criteria and are suitable for direct replacement in applications requiring 2 A average rectified current at 30 V reverse voltage:

SL23-E3/52T (Vishay): Active status, ROHS3 compliant, Cut Tape packaging, forward voltage 440 mV @ 2 A
SL23-E3/5BT (Vishay): Active status, ROHS3 compliant, Tape & Reel packaging, forward voltage 440 mV @ 2 A
SS23 (Taiwan Semiconductor Corporation): Active status, ROHS3 compliant, Tape & Reel packaging, forward voltage 500 mV @ 2 A
SS23-E3/52T (Vishay): Active status, ROHS3 compliant, Cut Tape packaging, extended temperature range to -65°C, forward voltage 500 mV @ 2 A

Parts with Different Current Ratings (Not Direct Equivalents):

The following parts have different average rectified current ratings and do not meet the primary substitution criteria for 2 A applications:

SK13_R1_00001 (Panjit): 1 A rating (below requirement)
SK33B-LTP (Micro Commercial Co): 3 A rating (above requirement), Not For New Designs status
SK43BL-TP (Micro Commercial Co): 4 A rating (above requirement), Not For New Designs status
STPS130U (STMicroelectronics): 1 A rating (below requirement)
STPS1L30U (Vishay): 1 A rating (below requirement), Obsolete status, RoHS non-compliant

Compliance and Product Status Considerations:

All direct equivalents maintain ROHS3 compliance and Active product status, ensuring long-term availability and regulatory alignment. Parts designated as "Not For New Designs" or "Obsolete" are not recommended for new circuit designs. The STPS1L30U is RoHS non-compliant and should not be used in applications requiring RoHS certification.

Frequently Asked Questions (FAQ)

Q: Can I use SK13_R1_00001 (1 A) as a substitute for B130LB-13-F (2 A)?

A: No. The SK13_R1_00001 has a maximum average rectified current of 1 A, which is insufficient for applications designed for 2 A operation. Using an undersized component will result in thermal stress and potential failure.

Q: What is the difference between SL23-E3/52T and SL23-E3/5BT?

A: Both parts are manufactured by Vishay with identical electrical specifications (30 V, 2 A, 440 mV forward voltage). The primary difference is packaging: SL23-E3/52T is supplied in Cut Tape (CT) & Digi-Reel format, while SL23-E3/5BT is supplied in Tape & Reel (TR) format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Why are SK33B-LTP and SK43BL-TP listed if they have different current ratings?

A: These parts are listed because they appear in the manufacturer's cross-reference data for the B130LB-13-F. However, their 3 A and 4 A ratings, respectively, make them unsuitable for direct substitution in 2 A applications. Both are also designated "Not For New Designs," limiting their use in new product development.

Q: Is SS23-E3/52T suitable for applications requiring operation below -55°C?

A: Yes. The SS23-E3/52T has an operating temperature range of -65°C to 125°C, extending 10°C lower than the B130LB-13-F (-55°C to 125°C). This makes it suitable for applications requiring extended low-temperature operation.

Q: Can I use STPS1L30U as a substitute?

A: No. The STPS1L30U is classified as Obsolete and is RoHS non-compliant. Additionally, its 1 A rating is below the 2 A requirement. New designs should not incorporate this part.

Q: What is the significance of forward voltage differences between substitute parts?

A: Forward voltage (Vf) affects power dissipation and circuit efficiency. The B130LB-13-F has a Vf of 445 mV @ 2 A. Substitute parts range from 440 mV to 500 mV @ 2 A. Lower forward voltage reduces heat generation; higher forward voltage increases power loss. Circuit design must account for these differences in thermal and efficiency calculations.

Q: Are all substitute parts RoHS3 compliant?

A: No. The STPS1L30U is RoHS non-compliant. All other listed substitutes are ROHS3 compliant. For applications requiring RoHS certification, only ROHS3-compliant parts should be selected.

Q: What packaging options are available for 2 A, 30 V equivalents?

A: Direct 2 A equivalents are available in Cut Tape (CT) & Digi-Reel format (SL23-E3/52T, SS23-E3/52T) and Tape & Reel (TR) format (SL23-E3/5BT, SS23). Selection depends on assembly line requirements and volume procurement strategies.
