RL107-N-2-4-AP Equivalent & Substitute Parts

Part Overview

The RL107-N-2-4-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, 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, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitution of the RL107-N-2-4-AP is determined by the following critical parameters: reverse voltage rating (1000 V), average rectified current capacity, forward voltage characteristics, recovery speed classification, reverse leakage current, and through-hole axial package format.

Substitute parts are grouped into two categories:

Parametric Equivalent: Parts that match all electrical specifications and maintain identical performance characteristics within the same voltage and current ratings.

Similar Substitute: Parts that satisfy the primary voltage and package requirements but operate at reduced current ratings or exhibit different electrical characteristics, suitable for applications with lower current demands.

Engineering Selection Recommendations

RL107GP-AP is the primary parametric equivalent for RL107-N-2-4-AP replacement. This part maintains identical electrical specifications across all critical parameters: 1000 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, standard recovery speed, 5 µA reverse leakage, and -55°C to 150°C operating temperature range. The RL107GP-AP is currently in active production status with ROHS3 compliance certification, providing direct functional substitution with improved supply availability.

AP01CWS functions as a similar substitute for applications requiring reduced current capacity. This part maintains the 1000 V reverse voltage rating and axial through-hole package format but is rated for 200 mA average rectified current with 4 V forward voltage at 200 mA. The AP01CWS exhibits higher reverse leakage current (100 µA @ 1000 V) and operates within a narrower temperature range (-40°C to 150°C). Selection of AP01CWS is appropriate only for circuits designed for 200 mA or lower current operation.

Both substitute parts carry RoHS compliance certifications and unlimited moisture sensitivity levels (MSL 1), supporting deployment in standard manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can RL107GP-AP directly replace RL107-N-2-4-AP in all applications?

A: Yes. RL107GP-AP is a parametric equivalent with identical electrical specifications. The primary difference is product status (active versus obsolete) and packaging format (Tape & Box versus standard). Both parts share the same base product number (RL107), voltage rating (1000 V), current rating (1 A), forward voltage (1.1 V @ 1 A), and operating temperature range (-55°C to 150°C).

Q: What are the limitations of AP01CWS as a substitute?

A: AP01CWS operates at 200 mA average rectified current, one-fifth the current capacity of RL107-N-2-4-AP. Forward voltage is significantly higher at 4 V @ 200 mA compared to 1.1 V @ 1 A. Reverse leakage current is elevated at 100 µA @ 1000 V versus 5 µA @ 1000 V. Operating temperature range is restricted to -40°C to 150°C. AP01CWS is suitable only for low-current applications within these thermal limits.

Q: Are there packaging differences between the substitute parts?

A: RL107-N-2-4-AP and RL107GP-AP both use axial through-hole A-405 package format. RL107GP-AP is supplied in Tape & Box (TB) packaging, while RL107-N-2-4-AP uses standard packaging. AP01CWS also employs axial through-hole format with identical mechanical compatibility. All three parts are compatible with standard through-hole PCB assembly processes.

Q: What compliance certifications apply to these parts?

A: RL107-N-2-4-AP and RL107GP-AP are ROHS3 compliant. AP01CWS is RoHS compliant. All three parts carry MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control designation. RL107GP-AP includes REACH Unaffected status.

Q: Which substitute should be selected for new designs?

A: RL107GP-AP is the recommended selection for new designs requiring 1 A at 1000 V. This part is in active production with full parametric equivalence to the obsolete RL107-N-2-4-AP and provides superior supply chain availability. AP01CWS should be selected only when circuit requirements are limited to 200 mA operation.
