Engineering Selection Recommendations
The RK 34 is designated as obsolete. Replacement selection can be made from substitute parts that meet RoHS compliance and offer status as active products with equivalent or compatible electrical and mechanical characteristics. BAT165E6327HTSA1 and SR304 A0G are both RoHS compliant and possess an MSL of 1 (Unlimited). Product status is active for both substitutes.
Frequently Asked Questions (FAQ)
Q: What criteria are used to determine equivalent and substitute diodes for the RK 34?
A: Substitution is determined by matching Schottky technology, DC reverse voltage rating (40 V), average rectified current, forward voltage, recovery speed, reverse leakage, package and mounting style, and compliance with environmental and product status criteria.
Q: How does package type impact selection for the RK 34 substitutes?
A: The original RK 34 is an axial through-hole diode. The SR304 A0G maintains this through-hole, axial configuration. The BAT165E6327HTSA1 is a surface mount device, which may impact mechanical compatibility if a through-hole replacement is required.
Q: Are the substitute parts compliant with RoHS requirements?
A: Both BAT165E6327HTSA1 and SR304 A0G are listed as ROHS3 compliant, matching the compliance status of the RK 34.
Q: What is the product status of the substitute diodes compared to RK 34?
A: RK 34 is obsolete, whereas BAT165E6327HTSA1 and SR304 A0G are both active and available.
Q: Is there a difference in average rectified current rating among the substitutes?
A: BAT165E6327HTSA1 has a lower average rectified current (750mA), and SR304 A0G has a higher current rating (3A) compared to the RK 34 (2.5A).
