Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC18F2458T-I/SO is determined by strict equivalence across the following critical parameters:

• Manufacturer: Microchip Technology (same source)
• Series: PIC® 18F (same product line)
• Core Architecture: 8-Bit PIC core processor
• Speed: 48MHz operation
• Memory Configuration: 24KB FLASH (12K x 16), 256 x 8 EEPROM, 2K x 8 RAM
• I/O Count: 24 pins
• Connectivity: I2C, SPI, UART/USART, USB support
• Voltage Range: 4.2V ~ 5.5V supply
• Package Format: 28-SOIC surface mount
• Thermal Range: -40°C ~ 85°C operation
• Compliance: ROHS3 and REACH status

The primary variable between the main part and substitute is the packaging format (Tape & Reel versus Tube), which does not affect electrical or functional performance. Both parts maintain identical core specifications, memory architecture, and peripheral integration.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC18F2458T-I/SO and PIC18F2458-I/SO are active production parts from Microchip Technology with verified programmability. Selection between these parts is based solely on packaging and supply requirements:

• PIC18F2458T-I/SO (Tape & Reel): Suitable for high-volume automated assembly operations where continuous reel feeding is required.
• PIC18F2458-I/SO (Tube): Suitable for lower-volume production, manual assembly, or applications where tube packaging is preferred for handling and storage.

Both parts maintain identical electrical performance, memory architecture, peripheral integration, and compliance certifications (ROHS3, REACH Unaffected). The choice between them does not affect circuit design, firmware compatibility, or functional behavior. Current inventory availability shows 1900 units of the tube-packaged variant against 1021 units of the tape-and-reel variant.

Frequently Asked Questions (FAQ)

Q: Are PIC18F2458T-I/SO and PIC18F2458-I/SO electrically interchangeable?

A: Yes. Both parts are identical in all electrical specifications, memory configuration, operating voltage, temperature range, and peripheral functionality. The only difference is the packaging format (Tape & Reel versus Tube).

Q: Can I use PIC18F2458-I/SO as a direct replacement in my design?

A: Yes, provided your assembly process can accommodate tube packaging instead of tape-and-reel. No circuit modifications, firmware changes, or PCB layout adjustments are required.

Q: Does the packaging format affect the component's performance?

A: No. Packaging format is a supply chain and manufacturing consideration only. It does not influence electrical performance, memory access, peripheral operation, or thermal characteristics.

Q: Are both parts ROHS3 compliant?

A: Yes. Both PIC18F2458T-I/SO and PIC18F2458-I/SO are ROHS3 compliant with MSL rating 1 (Unlimited moisture sensitivity level).

Q: What is the pin count and package type?

A: Both parts use a 28-pin SOIC package (0.295" width, 7.50mm) in surface mount configuration. Pin assignments and functionality are identical.

Q: Can I mix these parts in the same production batch?

A: Yes. Since all electrical and functional parameters are identical, both parts can be used interchangeably within the same design and production run. Only the packaging format differs.
