Substitute Part Grouping Explanation

Substitution eligibility for the 24LC32AF-I/P is determined by strict alignment of the following critical parameters:

Core Electrical Parameters:

  • Memory capacity: 32Kbit
  • Memory organization: 4K x 8
  • Interface protocol: I2C
  • Clock frequency: 400 kHz
  • Access time: 900 ns
  • Write cycle time: 5ms

Physical Parameters:

  • Package type: 8-DIP (0.300", 7.62mm)
  • Mounting method: Through Hole

Environmental & Compliance Parameters:

  • RoHS3 compliance status
  • Moisture sensitivity level: 1 (Unlimited)
  • REACH status: REACH Unaffected

Substitute parts must maintain identical memory specifications, I2C protocol compatibility, and 8-DIP package configuration. Voltage supply range variations are permitted when the substitute range encompasses or exceeds the original specification. Operating temperature range may extend beyond the original specification without affecting substitution eligibility.
