RL 2Z Equivalent & Substitute Parts Reference

Part Overview

The RL 2Z by Sanken Electric USA Inc. is a 200 V, 2A, fast recovery through-hole diode intended for general rectification applications. The product status is Obsolete. As RL 2Z is no longer manufactured or supported, alternative models from other vendors with matching electrical and mechanical characteristics are required for new designs and maintenance of existing circuits.

Substitute Part Grouping Explanation

Substitute parts are selected based on strict alignment with the following key parameters:

Maximum reverse voltage (Vr) of 200 V
Average rectified current (Io) of 2A
Fast-recovery speed where trr is ≤ 500 ns and operating at > 200 mA
Reverse recovery time (trr) as a key switching performance value
Maximum forward voltage (Vf) at specified test current
Maximum reverse leakage current at rated voltage
Mounting style: Through Hole
Package/case corresponding to axial styles for direct mechanical replacement
Operating temperature rating encompassing the typical deployment environment.

Only substitutes meeting all above parameters are presented.

Engineering Selection Recommendations

For replacement of the obsolete RL 2Z diode, select only active substitute parts matching all required technical attributes as outlined in the parameter comparison. Prioritize fully compliant devices with RoHS3/REACH status as indicated in each substitute's documentation. Substitutes with current "Active" status and equal or better electrical performance are suitable for new or legacy applications within the specified environmental and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: What are the essential criteria for selecting an equivalent or substitute diode for RL 2Z?
A: The substitute must match maximum reverse voltage (200 V), average rectified current (2A), fast recovery speed (≤ 500 ns), comparable or lower forward voltage and reverse leakage current, compatible through-hole mounting, and similar or wider operating temperature range.

Q: Do all listed substitutes have the same packing and mounting type?
A: All substitutes use through-hole mounting with axial or similar package geometry suitable for direct replacement in most designs that used the original RL 2Z.

Q: How does RoHS and REACH compliance impact part selection?
A: Select substitutes with documented RoHS3 and REACH status for compatibility with environmental and safety requirements, especially in regulated markets.

Q: Can forward voltage or reverse recovery time differences impact substitution?
A: All listed substitutes have forward voltage (Vf) and reverse recovery time (trr) equal to or better than the original. These parameters are within the allowable variation for this product category, supporting direct substitution.

Q: What should be considered regarding product lifecycle status?
A: Preference should be given to substitutes marked "Active" to ensure ongoing supply and support. Parts not for new designs or obsolete may not be suitable for future production requirements.
