MUR1100-TP Equivalent & Substitute Parts

Part Overview

The MUR1100-TP is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for ongoing design support, production continuity, and long-term component availability.

Substitute Part Grouping Explanation

Substitute parts for the MUR1100-TP are classified based on electrical parameter compatibility within the rectifier diode category. The primary substitution criteria are:

Critical Parameters for Substitution:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 1000 V
Current - Average Rectified (Io): Must equal or exceed 1 A
Mounting Type: Through Hole
Package / Case: DO-204AL, DO-41, or Axial configuration

Direct Equivalent Classification: Parts meeting all critical parameters with matching or superior electrical characteristics and active product status qualify as direct equivalents.

Similar Part Classification: Parts with reduced voltage ratings (800 V) or different recovery characteristics are classified as similar substitutes. These parts maintain the same current rating and package form factor but operate within a narrower voltage specification window.

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

UF4007GP-TP from Micro Commercial Co is the direct equivalent to MUR1100-TP. Both parts share identical voltage and current ratings, matching fast recovery characteristics with 75 ns reverse recovery time, and equivalent forward voltage specifications. UF4007GP-TP maintains active product status with ROHS3 compliance and unlimited moisture sensitivity level. This part provides the closest electrical and thermal performance match to the obsolete MUR1100-TP.

Alternative Equivalents (1000 V Rating):

The following Vishay General Semiconductor parts meet the 1000 V voltage requirement and 1 A current rating with active product status:

1N4007-E3/53 and 1N4007-E3/54: Standard recovery diodes with 1.1 V forward voltage
1N4007E-E3/53: Standard recovery with 2 µs reverse recovery time
1N4007GP-E3/53 and 1N4007GPE-E3/53: SUPERECTIFIER® series with extended temperature range (-65°C ~ 175°C) matching the original part
1N4249GP-E3/54: SUPERECTIFIER® series with 1.2 V forward voltage and -65°C ~ 160°C operating range

All listed alternatives are ROHS3 compliant with unlimited moisture sensitivity level.

Reduced Voltage Alternatives (800 V Rating):

1N4006-E3/53 and 1N4006-E3/54 from Vishay General Semiconductor are suitable for applications where 800 V reverse voltage rating is sufficient. These parts feature lower forward voltage (1.1 V) and standard recovery characteristics. Selection of 800 V parts requires confirmation that circuit design margins accommodate the reduced voltage specification.

Frequently Asked Questions (FAQ)

Q: Can UF4007GP-TP directly replace MUR1100-TP without circuit modification?

A: UF4007GP-TP is electrically compatible as a direct substitute. Both parts share 1000 V reverse voltage, 1 A current rating, 75 ns reverse recovery time, and equivalent forward voltage characteristics. The operating temperature range of UF4007GP-TP (-55°C ~ 150°C) is narrower than MUR1100-TP (-65°C ~ 175°C), requiring verification that application temperature requirements fall within this range.

Q: What is the difference between fast recovery and standard recovery diodes in this comparison?

A: MUR1100-TP and UF4007GP-TP feature fast recovery characteristics with reverse recovery time of 75 ns. The Vishay 1N4007 series parts feature standard recovery with reverse recovery times of 2 µs or unspecified values. Fast recovery diodes switch more rapidly, reducing switching losses in high-frequency applications. Standard recovery diodes are suitable for lower-frequency rectification circuits.

Q: Are the 1N4006 series parts (800 V) suitable replacements?

A: 1N4006-E3/53 and 1N4006-E3/54 maintain the same 1 A current rating and through-hole DO-41 package configuration. The 800 V reverse voltage rating is 200 V lower than the original MUR1100-TP specification. These parts are suitable only for applications where circuit design margins accommodate the reduced voltage specification and where peak reverse voltages do not approach 800 V.

Q: What packaging options are available for substitute parts?

A: All substitute parts listed maintain through-hole mounting in DO-204AL, DO-41, or axial package configurations, ensuring mechanical compatibility with existing PCB layouts. Specific packaging variants (such as Cut Tape or bulk) are available for different procurement requirements.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance status of the original MUR1100-TP. All parts are REACH unaffected and classified under ECCN EAR99.

Q: Which substitute part offers the widest operating temperature range?

A: UF4007GP-TP, 1N4007GP-E3/53, 1N4007GPE-E3/53, and 1N4249GP-E3/54 all support the extended temperature range of -65°C ~ 175°C (or -65°C ~ 160°C for 1N4249GP-E3/54), matching or approaching the original MUR1100-TP specification of -65°C ~ 175°C.
