Substitute Part Grouping Explanation

Substitution of the S5AC-13 is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 50 V minimum
Current - Average Rectified (Io): 5 A minimum
Mounting Type: Surface Mount
Package / Case: DO-214AB or SMC compatible
Speed: Standard Recovery >500ns, > 200mA (Io)

Acceptable Parameter Variations:

Forward voltage (Vf) may vary within standard rectifier tolerances
Reverse leakage current (Ir) may be lower than specified
Capacitance values may differ
Operating temperature range may extend beyond original specification
RoHS compliance status may differ from original part

Parts are grouped into two categories: parametric equivalents (identical electrical specifications) and manufacturer-recommended substitutes (compatible performance with allowable variations).

Engineering Selection Recommendations

Parametric Equivalent (Recommended Primary Substitute):

S5AC-13-F is the direct parametric equivalent to the S5AC-13. This part maintains identical electrical specifications including 50 V reverse voltage, 5 A average rectified current, 1.15 V forward voltage at 5 A, and 40 pF capacitance. The S5AC-13-F is manufactured by Diodes Incorporated and carries Active product status with ROHS3 compliance. This part is available in higher inventory quantities (30200 pcs) and is suitable for new designs.

Manufacturer-Recommended Substitutes:

CGRC501-G (Comchip Technology) provides electrical equivalence with 50 V reverse voltage and 5 A current rating. This part is Active and ROHS3 compliant. Capacitance specification is not provided for this part.

S5AL-TP (Micro Commercial Co) maintains 50 V reverse voltage and 5 A current rating with forward voltage of 1.2 V at 5 A. This part carries "Not For New Designs" status and exhibits higher capacitance (100 pF) compared to the original specification.

S10A-TP (Micro Commercial Co) provides 50 V reverse voltage with doubled current rating of 10 A, making it suitable for applications requiring higher current capacity. This part is classified as Obsolete.

SMLJ60S05-TP (Micro Commercial Co) offers 50 V reverse voltage with 6 A current rating and superior forward voltage performance (1 V at 6 A). This part is classified as "Not For New Designs" and exhibits higher capacitance (150 pF).

Compliance Considerations:

The original S5AC-13 is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, meeting current regulatory requirements for new production and design applications.

Frequently Asked Questions (FAQ)

Q: Can S5AC-13-F be used as a direct replacement for S5AC-13?

A: Yes. S5AC-13-F is a parametric equivalent with identical electrical specifications. Both parts are rated for 50 V reverse voltage, 5 A average rectified current, 1.15 V forward voltage at 5 A, and 40 pF capacitance. Both use the DO-214AB SMC package. The primary difference is product status: S5AC-13-F is Active while S5AC-13 is discontinued.

Q: What is the difference between S5AC-13-F and CGRC501-G?

A: Both parts meet the core electrical requirements of 50 V reverse voltage and 5 A current rating. S5AC-13-F is manufactured by Diodes Incorporated, while CGRC501-G is manufactured by Comchip Technology. CGRC501-G does not specify capacitance value. Both are ROHS3 compliant and Active products.

Q: Can S10A-TP be used in place of S5AC-13?

A: S10A-TP meets the 50 V reverse voltage requirement and exceeds the 5 A current requirement with a 10 A rating. However, S10A-TP is classified as Obsolete. The higher current rating makes it suitable for applications requiring greater current capacity, but it is not recommended for new designs.

Q: What is the significance of the "Not For New Designs" status?

A: Parts marked "Not For New Designs" (S5AL-TP and SMLJ60S05-TP) are available for existing production and maintenance applications but should not be selected for new circuit designs. These parts may have limited future availability or support.

Q: Are all substitute parts in the same package?

A: Yes. All listed parts use the DO-214AB SMC surface mount package, ensuring mechanical and thermal compatibility with the original S5AC-13 footprint.

Q: What is the impact of different capacitance values among substitute parts?

A: The original S5AC-13 specifies 40 pF capacitance at 4 V, 1 MHz. S5AL-TP specifies 100 pF and SMLJ60S05-TP specifies 150 pF. Higher capacitance may affect high-frequency circuit performance and switching characteristics. CGRC501-G does not specify capacitance. Capacitance differences should be evaluated against specific circuit requirements.

Q: Why is RoHS compliance important for substitute selection?

A: The original S5AC-13 is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory standards. For new production and designs subject to RoHS requirements, ROHS3 compliant substitutes are necessary.

Q: Can SMLJ60S05-TP be used if lower forward voltage is required?

A: SMLJ60S05-TP exhibits 1 V forward voltage at 6 A, which is lower than the original S5AC-13 specification of 1.15 V at 5 A. However, this part is rated for 6 A current and carries "Not For New Designs" status. Forward voltage performance should be verified against specific circuit requirements before selection.
