Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16CE623T-20E/SS is determined by strict alignment of the following electrical and mechanical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating speed (20MHz)
• Program memory capacity (896B / 512 x 14)
• Program memory type (OTP)
• EEPROM capacity (128 x 8)
• RAM capacity (96 x 8)
• I/O count (13 pins)
• Supply voltage range (3V ~ 5.5V)
• Package type (20-SSOP)
• Peripheral set (Brown-out Detect/Reset, POR, WDT)

The primary substitute identified is PIC16CE623-20I/SS, which maintains identical electrical specifications and package configuration. The distinction between the main part and substitute lies in product status (obsolete versus active) and operating temperature range variance.

Parameter Comparison

Engineering Selection Recommendations

The PIC16CE623-20I/SS serves as the direct active equivalent to the obsolete PIC16CE623T-20E/SS. Both parts maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing designs. The substitute part carries active product status with verified programmability through DiGi-Electronics, providing assured supply chain availability and technical support.

The operating temperature range of the substitute part (-40°C to 85°C) is narrower than the main part (-40°C to 125°C). Applications requiring operation above 85°C must evaluate this constraint against specific thermal requirements. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, supporting standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can PIC16CE623-20I/SS directly replace PIC16CE623T-20E/SS in existing designs?

A: Yes, the electrical and mechanical specifications are identical. The substitute part operates within the same voltage range (3V ~ 5.5V), maintains the same 20MHz speed, and uses the identical 20-SSOP package. The primary consideration is the operating temperature range, which extends to 85°C rather than 125°C.

Q: What is the significance of the product status difference?

A: The main part is classified as obsolete, indicating discontinued manufacturing and limited availability. The substitute part maintains active status, ensuring ongoing production, supply chain support, and technical documentation availability from Microchip Technology.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 20-SSOP (0.209", 5.30mm Width) surface mount package with identical pinout and mechanical dimensions, allowing direct PCB footprint compatibility.

Q: How do the memory specifications compare?

A: Both parts feature identical memory configurations: 896B program memory (512 x 14), 128 x 8 EEPROM, and 96 x 8 RAM. No functional memory differences exist between the parts.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and carry unlimited moisture sensitivity classification (MSL 1), meeting standard environmental and handling requirements for surface mount components.
