Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6A05 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 50 V minimum
• Current - Average Rectified (Io): 6 A minimum
• Package / Case: R-6, Axial through-hole configuration
• Mounting Type: Through Hole

Acceptable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Substitute values up to 1 V @ 6 A are acceptable
• Speed: Both standard recovery (>500ns) and fast recovery (≤500ns) technologies are acceptable
• Current - Reverse Leakage @ Vr: Substitute values up to 10 µA @ 50 V are acceptable
• Capacitance @ Vr, F: Substitute values up to 150 pF @ 4V, 1MHz are acceptable
• Operating Temperature - Junction: Substitute ranges must encompass minimum -55°C and maximum 125°C

Substitute parts must maintain R-6 axial through-hole package compatibility and meet or exceed the electrical performance specifications of the original component.

Parameter Comparison

Engineering Selection Recommendations

6A05-TP (Micro Commercial Co): This substitute maintains identical electrical specifications to the original 6A05, including forward voltage, recovery speed, reverse leakage, and capacitance. The part is ROHS3 compliant and carries a "Not For New Designs" status, making it suitable for replacement in existing applications and legacy system maintenance. Operating temperature range is reduced to -55°C ~ 125°C, which is acceptable for most industrial and commercial applications.

HER601G B0G (Taiwan Semiconductor Corporation): This substitute meets all critical electrical requirements with equivalent 50 V reverse voltage and 6 A current ratings. The HER601G B0G features fast recovery characteristics (≤500ns) compared to the standard recovery of the original part, resulting in lower capacitance (80 pF versus 150 pF). This part carries Active product status and ROHS3 compliance, making it the preferred choice for new designs and long-term availability. Operating temperature range extends to -55°C ~ 150°C. The slightly higher forward voltage (1 V versus 950 mV) remains within acceptable limits for general-purpose rectification applications.

Frequently Asked Questions (FAQ)

Q: Can the 6A05-TP be used as a direct replacement for the obsolete 6A05?

A: Yes. The 6A05-TP maintains identical electrical specifications including 50 V reverse voltage, 6 A current rating, 950 mV forward voltage, and R-6 axial through-hole package configuration. The reduced operating temperature range (-55°C ~ 125°C versus -65°C ~ 175°C) is acceptable for standard industrial applications.

Q: What is the primary difference between the 6A05-TP and HER601G B0G substitutes?

A: The HER601G B0G features fast recovery technology (≤500ns) with lower capacitance (80 pF), compared to the standard recovery (>500ns) and higher capacitance (150 pF) of the 6A05-TP. Both meet the core electrical requirements. The HER601G B0G carries Active product status, providing superior long-term availability.

Q: Are all substitute parts compatible with the original R-6 axial through-hole footprint?

A: Yes. All substitute parts specified use the R-6 axial package configuration and through-hole mounting type, ensuring mechanical and footprint compatibility with existing PCB designs.

Q: What compliance certifications apply to the substitute parts?

A: Both 6A05-TP and HER601G B0G are ROHS3 compliant. All parts listed carry REACH Unaffected status and EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: Which substitute part should be selected for new product designs?

A: The HER601G B0G is recommended for new designs due to its Active product status, ensuring long-term availability and supply chain stability. The fast recovery characteristics and lower capacitance provide improved performance in switching applications.

Q: Is the forward voltage difference between substitutes significant?

A: The forward voltage difference between 950 mV (6A05, 6A05-TP) and 1 V (HER601G B0G) is 50 mV, representing a 5.3% increase. This difference is negligible for general-purpose rectification and does not affect circuit functionality in standard applications.

Q: Can the HER601G B0G be used in applications requiring the full -65°C ~ 175°C temperature range of the original 6A05?

A: No. The HER601G B0G operating temperature range is -55°C ~ 150°C. For applications requiring the full -65°C lower temperature limit, the 6A05-TP (-55°C ~ 125°C) is also insufficient. In such cases, alternative components with extended temperature ranges must be evaluated.
