Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT88SC0104CA-Y6H-T are identified based on the following critical parameters:

Package Compatibility: All substitute parts utilize the 8-UFDFN Exposed Pad package format with 2x3 dimensions, ensuring mechanical and electrical pin compatibility on printed circuit boards.

Memory Interface & Organization: Substitute parts maintain 1Kbit memory capacity with 128 x 8 memory organization and I2C interface protocol, supporting equivalent data storage and communication requirements.

Surface Mount Technology: All candidates are surface mount devices suitable for automated assembly processes identical to the main part.

Regulatory Compliance: Substitute parts maintain ROHS3 compliance and REACH Unaffected status, meeting the same environmental and regulatory requirements as the main part.

Operating Temperature Range: All substitute parts operate within the -40°C to 85°C temperature range, supporting equivalent thermal performance specifications.

Supply Voltage Compatibility: Substitute parts operate within overlapping voltage ranges that accommodate the main part's operational requirements.

The three identified substitute parts—AT24C01D-MAHM-T, AT24CS01-MAHM-T, and BR24G01NUX-3TTR—meet these core substitution criteria while maintaining functional equivalence for memory storage and I2C communication applications.

Engineering Selection Recommendations

AT24C01D-MAHM-T (Microchip Technology): This substitute maintains Microchip Technology manufacturer continuity with Active product status and ROHS3 compliance. The 1Kbit EEPROM with I2C interface and 1 MHz clock frequency provides functional equivalence. Supply voltage range of 1.7V to 3.6V and 4.5 µs access time support standard embedded applications. Available in Cut Tape and Digi-Reel® packaging formats with 5400 pieces in stock.

AT24CS01-MAHM-T (Microchip Technology): This substitute offers the same Microchip Technology manufacturer and Active product status with identical 1Kbit EEPROM capacity and I2C interface. The extended supply voltage range of 1.7V to 5.5V provides broader operational flexibility compared to AT24C01D-MAHM-T. Access time of 550 ns enables faster read operations. Tape & Reel packaging with 5100 pieces in stock.

BR24G01NUX-3TTR (Rohm Semiconductor): This substitute from Rohm Semiconductor provides 1Kbit EEPROM with I2C interface in an equivalent 8-UFDFN package. The 400 kHz clock frequency operates at lower speed than Microchip alternatives. Supply voltage range of 1.6V to 5.5V and MSL 1 rating (Unlimited moisture sensitivity) offer enhanced environmental tolerance. Highest inventory availability with 25060 pieces in stock.

All three substitutes maintain Active product status, ROHS3 compliance, REACH Unaffected designation, and identical HTSUS classification, ensuring regulatory and compliance equivalence with the main part.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the AT88SC0104CA-Y6H-T?

A: Substitution is based on package compatibility (8-UFDFN Exposed Pad, 2x3 dimensions), memory interface protocol (I2C), memory capacity (1Kbit, 128 x 8 organization), surface mount technology, operating temperature range (-40°C to 85°C), regulatory compliance (ROHS3, REACH Unaffected), and supply voltage overlap. All identified substitutes meet these core criteria.

Q: Are the substitute parts pin-compatible with the main part?

A: Yes. All substitute parts utilize the 8-UFDFN Exposed Pad package with identical 2x3 dimensions, ensuring mechanical and electrical pin compatibility on printed circuit boards designed for the AT88SC0104CA-Y6H-T.

Q: What is the difference between the three substitute options?

A: AT24C01D-MAHM-T operates at 1 MHz with 1.7V to 3.6V supply range and 4.5 µs access time. AT24CS01-MAHM-T operates at 1 MHz with extended 1.7V to 5.5V supply range and faster 550 ns access time. BR24G01NUX-3TTR operates at 400 kHz with 1.6V to 5.5V supply range and MSL 1 rating for unlimited moisture sensitivity. All maintain 5ms write cycle time.

Q: Do all substitutes have the same regulatory compliance?

A: All substitutes are ROHS3 compliant and REACH Unaffected. However, the main part carries ECCN 5A992C while substitutes carry EAR99 classification. All share identical HTSUS code 8542.32.0051.

Q: What packaging formats are available for the substitutes?

A: AT24C01D-MAHM-T is available in Cut Tape (CT) and Digi-Reel® formats. AT24CS01-MAHM-T and BR24G01NUX-3TTR are available in Tape & Reel (TR) format. The main part is supplied in Tape & Reel (TR) format.

Q: Which substitute has the best inventory availability?

A: BR24G01NUX-3TTR from Rohm Semiconductor has the highest inventory with 25060 pieces in stock, compared to 5400 pieces for AT24C01D-MAHM-T and 5100 pieces for AT24CS01-MAHM-T.

Q: Can I use these substitutes in applications requiring secure memory functionality?

A: The substitute parts are standard EEPROM devices, not secure memory components. The main part AT88SC0104CA-Y6H-T is classified as Secure Memory within the CryptoMemory® series. Application requirements for security features must be evaluated separately from memory capacity and interface compatibility.
