RL107 Equivalent & Substitute Parts Reference

Part Overview

The RL107 is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 1 A average rectified current in an axial through-hole package (A-405). This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. The RL107G serves as the direct functional equivalent with identical electrical specifications and identical mechanical packaging.

Engineering Selection Recommendations

The RL107G is the direct substitute for the obsolete RL107 based on complete electrical and mechanical parameter equivalence. Selection of the RL107G provides the following advantages:

Product Status: The RL107G maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete RL107.

Regulatory Compliance: The RL107G is ROHS3 compliant and subject to REACH regulations, meeting current environmental and safety standards required for new designs and procurement. The RL107 is classified as REACH Unaffected, indicating it does not fall under current regulatory scope.

Functional Compatibility: All electrical parameters, mechanical dimensions, and thermal characteristics are identical between the two parts. Direct substitution in existing circuit designs is supported without modification to PCB layouts, component footprints, or electrical schematics.

Inventory Availability: The RL107G is available in active stock (854 Pcs), whereas the RL107 is obsolete and subject to limited availability.

Frequently Asked Questions (FAQ)

Q: Can the RL107G be used as a direct replacement for the RL107 in existing designs?

A: Yes. The RL107G is electrically and mechanically identical to the RL107 across all specified parameters. No circuit modifications, PCB layout changes, or design alterations are required for substitution.

Q: What is the difference between the RL107 and RL107G?

A: The primary difference is product status. The RL107 is obsolete, while the RL107G is an active production part. The RL107G also carries ROHS3 compliance and is subject to REACH regulations. All electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical A-405 axial through-hole package with the same mechanical dimensions and lead configuration.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range is -65°C to 175°C for both the RL107 and RL107G.

Q: What are the voltage and current ratings?

A: Both parts are rated for 1000 V DC reverse voltage and 1 A average rectified current. Forward voltage drop is 1.1 V maximum at 1 A.

Q: Is the RL107G RoHS compliant?

A: Yes. The RL107G is ROHS3 compliant. The RL107 compliance status is not specified in the provided data.

Q: What is the reverse leakage current specification?

A: Both parts specify 5 µA maximum reverse leakage current at 1000 V.

Q: Can these diodes be used in high-frequency applications?

A: These are standard recovery diodes with recovery time greater than 500 ns at currents greater than 200 mA. They are classified as standard speed devices, not fast recovery or ultrafast diodes.
