1. A221P32Y5ZQ Substitution Conclusion This part is a highly viable direct replacement in terms of electrical and mechanical interfacing. The key differences are as follows: its rated current and voltage (6A/125V AC vs. the original part's 5A/120V AC) are slightly higher, and its electrical life (60,000 cycles vs. 40,000 cycles) is longer. This provides a higher performance margin and extended service life under identical operating conditions. However, it lacks the original part's "epoxy-sealed terminals" feature. In applications exposed to moisture, dust, or requiring protection against chemical vapor ingress, the long-term reliability of its terminals may be inferior to that of the original part. For clean and dry application environments, this part represents a performance-upgrade alternative.
