Key Parameters

Substitute Part Grouping Explanation

Substitution of the MUR110GP-AP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 1 A
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, or Axial equivalent
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Tolerance Ranges:

• Voltage - Forward (Vf) (Max) @ If: Within component-level variation (970 mV baseline)
• Reverse Recovery Time (trr): Within fast recovery specification (45 ns baseline)
• Current - Reverse Leakage @ Vr: Within specified limits (5 µA @ 100 V baseline)
• Operating Temperature - Junction: Must support -65°C minimum and 150°C maximum or broader range
• Capacitance @ Vr, F: Within typical variation for this device class

Compliance Requirements:

• RoHS3 Compliant status required
• REACH Unaffected status required

The UF4002 R1G from Taiwan Semiconductor Corporation meets all mandatory matching criteria and compliance requirements, qualifying it as a direct substitute for the MUR110GP-AP.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: UF4002 R1G

The UF4002 R1G qualifies as a direct electrical and mechanical substitute for the MUR110GP-AP based on matched voltage, current, and package specifications. The substitute part carries Active product status, indicating ongoing manufacturer support and availability, whereas the MUR110GP-AP is designated "Not For New Designs."

Both parts maintain ROHS3 Compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent applications.

Operating Temperature Consideration:

The UF4002 R1G specifies a minimum junction operating temperature of -55°C, compared to -65°C for the MUR110GP-AP. Applications requiring operation below -55°C must retain the MUR110GP-AP or identify alternative parts with extended low-temperature ratings.

Forward Voltage and Recovery Time:

The UF4002 R1G exhibits a forward voltage of 1 V @ 1 A, compared to 970 mV for the MUR110GP-AP. This 30 mV difference is within component-level tolerance for general-purpose rectifier applications. Reverse recovery time increases from 45 ns to 50 ns, remaining within the fast recovery classification and acceptable for standard switching applications.

Inventory and Sourcing:

The UF4002 R1G maintains 693 pieces in new original stock, providing immediate availability for production and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the UF4002 R1G be used as a direct replacement for the MUR110GP-AP in existing designs?

A: Yes, the UF4002 R1G is electrically and mechanically equivalent for applications operating within -55°C to 150°C. Both parts share identical voltage and current ratings, fast recovery speed classification, and DO-41 through-hole packaging. The 30 mV forward voltage difference and 5 ns reverse recovery time increase are within acceptable tolerance for general-purpose rectification.

Q: What is the significance of the "Not For New Designs" status on the MUR110GP-AP?

A: This designation indicates the MUR110GP-AP has been superseded in the manufacturer's product line. New designs should incorporate the UF4002 R1G or equivalent active-status alternatives to ensure long-term availability and manufacturer support.

Q: Are there package compatibility concerns between the MUR110GP-AP and UF4002 R1G?

A: No. Both parts use identical through-hole axial packaging (DO-204AL / DO-41). Physical dimensions and lead spacing are compatible for direct board-level substitution without layout modifications.

Q: Does the UF4002 R1G meet the same compliance standards as the MUR110GP-AP?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, satisfying equivalent regulatory requirements for industrial and commercial applications.

Q: What is the impact of the -55°C minimum temperature specification on the UF4002 R1G?

A: Applications requiring continuous operation below -55°C must use the MUR110GP-AP (rated to -65°C) or identify alternative parts with extended low-temperature ratings. For standard industrial applications operating above -55°C, the UF4002 R1G presents no temperature-related limitation.

Q: How do the reverse recovery times compare between these parts?

A: The MUR110GP-AP specifies 45 ns reverse recovery time; the UF4002 R1G specifies 50 ns. Both remain within the fast recovery classification (≤ 500 ns for > 200 mA). The 5 ns difference is negligible for general-purpose rectification and does not affect switching performance in standard applications.

Q: Is the capacitance difference between the parts significant?

A: The MUR110GP-AP specifies 15 pF @ 4V, 1MHz; the UF4002 R1G specifies 17 pF @ 4V, 1MHz. This 2 pF difference is within normal component variation and does not affect circuit performance in typical rectifier applications.
