It is a surface-mount land-grid array — no leads, just pads on the bottom. The board footprint is compact, but rework requires a hot-air station or reflow oven; hand-soldering is not practical. The -40°C to 85°C operating temperature covers industrial environments: outdoor telecom cabinets, factory-floor PLCs, and HVAC controllers. ## Lifecycle and sourcing The MAX31329ELB+ is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is listed. No direct second-source or pin-compatible alternate is listed in the official cross-reference.","metaTitle":"MAX31329ELB+ I2C RTC Clock/Calendar, 64B RAM","metaDescription":"MAX31329ELB+ I2C real-time clock with alarm, leap year, 64B RAM, trickle charger. 1.6V-5.5V supply, 0.5µA timekeeping.
