Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24FC16HT-E/SN are determined by strict equivalence across the following critical parameters:

• Memory capacity: 16Kbit
• Memory organization: 2K x 8 bit configuration
• Interface protocol: I2C serial communication
• Operating frequency: 1 MHz maximum
• Access time: 450 ns
• Supply voltage range: 1.7V to 5.5V
• Temperature operating range: -40°C to 125°C
• Package specification: 8-SOIC form factor with 0.154" width (3.90mm)
• Surface mount technology compatibility
• RoHS3 compliance requirement
• MSL rating: Level 3

The 24FC16T-E/SN qualifies as a parametric equivalent substitute based on identical electrical characteristics, memory specifications, interface protocol, timing parameters, voltage ratings, temperature range, and physical package dimensions. Both parts share the same base product number (24FC16) and are manufactured by Microchip Technology under identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 24FC16HT-E/SN and 24FC16T-E/SN are active production components from Microchip Technology with full RoHS3 compliance and identical electrical and mechanical specifications. The 24FC16T-E/SN substitute part offers significantly higher inventory availability (3917 units versus 874 units), making it suitable for applications requiring immediate procurement or high-volume deployment. Both parts maintain identical performance characteristics across all critical parameters including memory capacity, interface protocol, timing specifications, voltage ratings, and temperature operating range. Selection between these parts should be based on inventory availability and supply chain requirements, as they are functionally interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the 24FC16T-E/SN be used as a direct replacement for the 24FC16HT-E/SN in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, memory organization, I2C interface protocol, timing characteristics, voltage supply range, operating temperature range, and 8-SOIC package dimensions. No circuit modifications are required for substitution.

Q: Are there any differences in the physical package between these two parts?

A: No. Both parts use the 8-SOIC package with 0.154" width (3.90mm). Pin configuration, lead spacing, and PCB footprint requirements are identical.

Q: What is the significance of the different part number suffixes (HT versus T)?

A: The suffix variation indicates different manufacturing process or tape reel specifications within Microchip Technology's product line. Both parts meet identical functional and compliance requirements for the 24FC16 base product.

Q: Do both parts have the same RoHS and compliance certifications?

A: Yes. Both the 24FC16HT-E/SN and 24FC16T-E/SN are ROHS3 compliant with identical MSL rating of Level 3 (168 Hours), REACH unaffected status, and EAR99 ECCN classification.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: 16Kbit memory capacity, 2K x 8 memory organization, I2C serial interface, 1 MHz clock frequency, 450 ns access time, 5ms write cycle time, 1.7V to 5.5V supply voltage range, and -40°C to 125°C operating temperature range.

Q: Is the 24FC16T-E/SN available in higher quantities?

A: Yes. The 24FC16T-E/SN has 3917 units in new original stock compared to 874 units for the 24FC16HT-E/SN, providing better availability for volume applications.
