Substitute Part Grouping Explanation

Substitute parts for the 602-00013 are identified based on strict electrical and mechanical parameter equivalence within the EEPROM memory device category. The substitution logic is structured into two distinct groups:

Direct Equivalent (Functional Replacement): The Microchip Technology 24AA128-I/P maintains complete parameter parity with the 602-00013 across all critical specifications. This part shares identical memory capacity (128Kbit), organization (16K x 8), interface protocol (I2C), clock frequency (400 kHz), access time (900 ns), write cycle time (5 ms), supply voltage range (1.7V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and physical packaging (8-DIP through-hole). The 24AA128-I/P is classified as an Active product with current manufacturer support, RoHS3 compliance, and REACH unaffected status.

Enhanced Performance Alternative (Functional Replacement with Improved Specifications): The Microchip Technology 24FC128-I/P provides functional substitution with enhanced performance characteristics. While maintaining identical memory capacity, organization, supply voltage, temperature range, and packaging, the 24FC128-I/P operates at an elevated clock frequency of 1 MHz (compared to 400 kHz) and delivers faster access time of 400 ns (compared to 900 ns). Write cycle time remains equivalent at 5 ms. The 24FC128-I/P is an Active product with verified DiGi-Electronics programmability, RoHS3 compliance, and REACH unaffected status.

Critical Substitution Parameters:

• Memory Size: 128Kbit (fixed requirement)
• Memory Organization: 16K x 8 (fixed requirement)
• Memory Interface: I2C (fixed requirement)
• Supply Voltage: 1.7V ~ 5.5V (fixed requirement)
• Operating Temperature: -40°C ~ 85°C (fixed requirement)
• Package Type: 8-DIP through-hole (fixed requirement)

Engineering Selection Recommendations

For Direct Functional Replacement: The Microchip Technology 24AA128-I/P is the appropriate selection when exact electrical and timing parameter equivalence is required. This part maintains identical performance specifications to the 602-00013 while offering the advantage of Active product status with ongoing manufacturer support. The 24AA128-I/P carries RoHS3 compliance certification, exceeding the RoHS compliance level of the original part, and is designated as REACH unaffected. Selection of this part ensures design compatibility without modification to existing circuit timing or interface requirements.

For Enhanced Performance Applications: The Microchip Technology 24FC128-I/P is suitable for applications where improved access time and higher clock frequency operation provide system-level benefits. The 24FC128-I/P operates at 1 MHz clock frequency with 400 ns access time, compared to the 602-00013 specifications of 400 kHz and 900 ns respectively. This part maintains identical memory capacity, organization, supply voltage, temperature range, and physical packaging. The 24FC128-I/P is an Active product with verified DiGi-Electronics programmability, RoHS3 compliance, and REACH unaffected status. This selection is appropriate for new designs requiring faster I2C communication or reduced memory access latency within the same form factor and pinout.

Compliance Considerations: Both substitute parts exceed the compliance certifications of the original 602-00013. The transition from RoHS compliance to RoHS3 compliance represents enhanced environmental and hazardous substance restrictions. Both substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 24AA128-I/P directly replace the 602-00013 in existing designs without circuit modification?
