Substitute Part Grouping Explanation

Substitution of the LPC1113FBD48/302,1 is determined by strict equivalence across the following critical parameters:

• Core Architecture: ARM Cortex-M0 32-bit single-core processor
• Memory Configuration: 24KB FLASH program memory and 8KB RAM
• Operating Frequency: 50MHz maximum clock speed
• Supply Voltage Range: 1.8V to 3.6V
• Package Format: 48-LQFP (7x7mm) surface mount
• Connectivity Interfaces: I2C, SPI, UART/USART
• Peripheral Set: Brown-out Detect/Reset, Power-On Reset (POR), Watchdog Timer (WDT)
• I/O Count: 42 I/O pins
• Data Conversion: 8-channel 10-bit analog-to-digital converter
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The LPC1113FBD48/303,1 meets all these criteria and is classified as a direct substitute. The primary distinction between the main part and its substitute is the product status and packaging configuration, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The LPC1113FBD48/303,1 is a direct functional equivalent to the LPC1113FBD48/302,1. All electrical, mechanical, and performance parameters are identical. The substitute part is currently in active production status, whereas the original part is discontinued at DiGi Electronics. Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Selection of the LPC1113FBD48/303,1 is appropriate for new designs, production continuity, and component replacement applications where the LPC1113FBD48/302,1 is no longer available. The packaging configuration difference (tray for the substitute) does not affect functional compatibility and is a standard variation in component distribution.
