Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSPIC33FJ128MC506-I/PT is determined by strict equivalence across the following critical parameters:

• Core processor architecture (dsPIC)
• Core size (16-Bit)
• Execution speed (40 MIPs)
• Program memory capacity and type (128KB FLASH)
• RAM capacity (8K x 8)
• I/O pin count (53)
• Supply voltage range (3V ~ 3.6V)
• Package type and pin configuration (64-TQFP 10x10)
• Operating temperature range (-40°C ~ 85°C)
• Peripheral feature set (CANbus, I2C, IrDA, LINbus, SPI, UART/USART, Brown-out Detect/Reset, DMA, Motor Control PWM, POR, PWM, QEI, WDT)
• Data converter specifications (A/D 16x10b/12b)

The identified substitute part maintains identical electrical and mechanical specifications while representing a verified manufacturing revision or equivalent model designation.

Parameter Comparison

Engineering Selection Recommendations

Both the DSPIC33FJ128MC506-I/PT and DSPIC33FJ128MC506A-I/PT are active production devices from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts may be based on availability and inventory status. The DSPIC33FJ128MC506A-I/PT carries verified programmability certification through DiGi-Electronics, while the base DSPIC33FJ128MC506-I/PT does not have verified programmability status documented. Both parts maintain full compliance with ROHS3 and REACH regulatory requirements. Current inventory levels show 1380 units of the DSPIC33FJ128MC506-I/PT and 1110 units of the DSPIC33FJ128MC506A-I/PT available in stock.

Frequently Asked Questions (FAQ)

Q: Are DSPIC33FJ128MC506-I/PT and DSPIC33FJ128MC506A-I/PT pin-compatible?

A: Yes. Both devices use the 64-TQFP (10x10) package with identical pin configurations and 53 I/O pins. Direct PCB layout compatibility is maintained.

Q: Can these parts be used interchangeably in production?

A: The parts are electrically and mechanically equivalent. The primary difference is the manufacturing revision designation (A suffix) and verified programmability status of the DSPIC33FJ128MC506A-I/PT variant.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters remain identical: 16-bit core processor, 40 MIPs execution speed, 128KB FLASH program memory, 8KB RAM, 53 I/O pins, 3V to 3.6V supply voltage, 64-TQFP package, -40°C to 85°C operating temperature range, and identical peripheral feature set including CANbus, I2C, IrDA, LINbus, SPI, UART/USART, and motor control capabilities.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The DSPIC33FJ128MC506A-I/PT has verified DiGi-Electronics programmability certification, while the base model does not have this verification documented.

Q: What is the moisture sensitivity level for these devices?

A: Both parts have a Moisture Sensitivity Level (MSL) of 3 with a 168-hour floor life rating. Standard moisture control procedures apply during storage and handling.
