RL106-AP Equivalent & Substitute Parts

Part Overview

The RL106-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 1 A average rectified current in an axial through-hole package (A-405). This part is classified as obsolete, making identification of active equivalent components necessary for ongoing design support and procurement continuity. The RL106-AP operates across a junction temperature range of -55°C to 150°C and complies with ROHS3 standards.

Substitute Part Grouping Explanation

Substitution of the RL106-AP is determined by electrical and mechanical parameter equivalence. The primary substitute, RL106GP-AP, maintains identical electrical specifications across all critical parameters: 800 V reverse voltage rating, 1 A average rectified current, 1.1 V forward voltage drop at 1 A, 5 µA reverse leakage current at 800 V, standard recovery speed characteristics, and 15 pF capacitance at 4 V and 1 MHz. Both parts utilize the same axial through-hole package configuration (A-405) and operate within the identical junction temperature range of -55°C to 150°C.

The key substitution criteria are:

Voltage - DC Reverse (Vr) (Max): 800 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
Current - Reverse Leakage @ Vr: 5 µA @ 800 V
Package / Case: Axial
Mounting Type: Through Hole
Operating Temperature - Junction: -55°C to 150°C

Engineering Selection Recommendations

The RL106GP-AP is the direct equivalent substitute for the obsolete RL106-AP. Both parts are manufactured by Micro Commercial Co and share identical electrical and mechanical specifications. The RL106GP-AP holds active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

The primary distinction between the two parts is product status and packaging format. The RL106-AP is obsolete, while the RL106GP-AP is active. The RL106GP-AP is supplied in Tape & Box (TB) packaging, which is standard for active production components. This packaging difference does not affect electrical performance or mechanical compatibility in through-hole applications.

For new designs or ongoing procurement, the RL106GP-AP is the appropriate selection. For legacy system maintenance where the original RL106-AP is required, the RL106GP-AP provides full functional and electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the RL106GP-AP directly replace the RL106-AP in existing designs?

A: Yes. The RL106GP-AP is electrically and mechanically identical to the RL106-AP. Both parts have the same 800 V reverse voltage rating, 1 A current rating, forward voltage characteristics, and axial A-405 package configuration. Direct substitution is valid for all applications where the RL106-AP was originally specified.

Q: Why is the RL106-AP listed as obsolete?

A: The RL106-AP has been discontinued by the manufacturer. The RL106GP-AP is the active equivalent part that replaces it in the product line. Both parts share the same base product number (RL106) and identical electrical specifications.

Q: What is the difference between the RL106-AP and RL106GP-AP packaging?

A: The RL106-AP packaging format is not specified in the available data. The RL106GP-AP is supplied in Tape & Box (TB) packaging, which is standard for active production components. This packaging difference does not affect electrical performance or mechanical fit in through-hole applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the RL106-AP and RL106GP-AP are ROHS3 compliant. The RL106GP-AP additionally carries REACH Unaffected status.

Q: What are the critical electrical parameters for substitution?

A: The critical parameters that must match for substitution are: 800 V DC reverse voltage rating, 1 A average rectified current, 1.1 V maximum forward voltage at 1 A, 5 µA reverse leakage current at 800 V, and standard recovery speed characteristics. The RL106GP-AP meets all these requirements.

Q: Can the RL106GP-AP be used in high-temperature applications?

A: Yes. The RL106GP-AP operates across a junction temperature range of -55°C to 150°C, identical to the RL106-AP. This range supports both industrial and high-temperature applications within the specified limits.

Q: Is the axial package configuration the same for both parts?

A: Yes. Both the RL106-AP and RL106GP-AP use the axial A-405 package configuration for through-hole mounting. Physical dimensions and lead spacing are identical.
