Engineering Selection Recommendations

For Obsolete Equipment Maintenance: The MR752RL is obsolete. Both substitute parts meet the core electrical specifications (200 V, 6 A, standard recovery). The 6A2-TP is classified as "Not For New Designs," indicating limited long-term availability. The GI752-E3/54 carries Active product status, providing superior long-term supply assurance.

For RoHS Compliance: The MR752RL is RoHS non-compliant. Both substitute parts (6A2-TP and GI752-E3/54) are ROHS3 compliant, meeting modern regulatory requirements.

For Temperature Range Considerations: The MR752RL operates to 175°C junction temperature. The GI752-E3/54 operates to 150°C, and the 6A2-TP to 125°C. Applications requiring the full -65°C to 175°C range of the original part require thermal analysis to confirm substitute adequacy.

For Reverse Leakage Performance: The GI752-E3/54 exhibits the lowest reverse leakage current (5 µA @ 200 V) compared to the original part (25 µA @ 200 V), providing improved performance in this parameter.

Frequently Asked Questions (FAQ)

Q: Can the 6A2-TP directly replace the MR752RL in existing designs?

A: The 6A2-TP meets all core electrical requirements (200 V, 6 A, standard recovery, through-hole mounting). Physical package differences exist (R-6 versus Microde Button), requiring PCB layout verification. Operating temperature range is reduced to -55°C to 125°C.

Q: Is the GI752-E3/54 suitable for new designs?

A: The GI752-E3/54 carries Active product status and ROHS3 compliance, making it suitable for new designs. It meets all electrical specifications of the MR752RL with equivalent forward voltage (900 mV @ 6 A) and superior reverse leakage performance (5 µA @ 200 V).

Q: What are the package differences between these parts?

A: The MR752RL uses a Microde Button package. The 6A2-TP uses an R-6 package. The GI752-E3/54 uses a P600 package. All are axial through-hole configurations, but physical dimensions and PCB footprints differ. Mechanical compatibility must be verified for each application.

Q: Are all substitute parts RoHS compliant?

A: The MR752RL is RoHS non-compliant. Both substitute parts (6A2-TP and GI752-E3/54) are ROHS3 compliant, meeting current environmental regulations.

Q: What is the reverse recovery time specification?

A: The MR752RL and 6A2-TP do not specify reverse recovery time (trr). The GI752-E3/54 specifies 2.5 µs reverse recovery time. All three parts are classified as standard recovery devices with recovery time >500 ns at >200 mA.

Q: How do reverse leakage currents compare?

A: The MR752RL specifies 25 µA @ 200 V. The 6A2-TP specifies 10 µA @ 200 V. The GI752-E3/54 specifies 5 µA @ 200 V. Lower reverse leakage improves efficiency in high-impedance circuits.
