Substitute Part Grouping Explanation

Substitution for the PIC16C56-10E/SS is determined by strict equivalence across the following critical parameters:

  • Core Architecture: PIC 8-bit processor
  • Memory Configuration: 1.5KB OTP program memory (1K x 12), 25 x 8 RAM
  • Clock Speed: 10MHz operation
  • I/O Count: 12 I/O pins
  • Supply Voltage: 4.5V to 5.5V range
  • Package: 20-SSOP form factor with identical pinout
  • Peripherals: POR (Power-On Reset) and WDT (Watchdog Timer)

The PIC16C56-10I/SS qualifies as a direct substitute based on identical electrical specifications and package compatibility. The primary distinction lies in product status and operating temperature range, which do not affect functional interchangeability in applications designed for the original part.

Engineering Selection Recommendations

The PIC16C56-10I/SS is a direct functional equivalent to the PIC16C56-10E/SS. Both parts share identical electrical specifications, memory architecture, I/O configuration, and package geometry. The substitute part carries Active product status, ensuring continued availability and supply chain support compared to the Obsolete classification of the original part.

The operating temperature range difference (-40°C to 85°C for the substitute versus -40°C to 125°C for the main part) represents a narrower specification window. Applications requiring operation above 85°C must retain the original part number or evaluate alternative solutions outside this product family.

Both parts maintain ROHS3 compliance and identical MSL ratings, supporting equivalent handling and storage requirements. The substitute part is verified as programmable through DiGi-Electronics, confirming production readiness.

Frequently Asked Questions (FAQ)

Q: Can PIC16C56-10I/SS replace PIC16C56-10E/SS in all applications?

A: Yes, for applications operating within -40°C to 85°C. The electrical specifications, memory configuration, I/O count, and package are identical. Applications requiring operation above 85°C must use the original part.

Q: What is the significance of the "E" and "I" designators in the part numbers?

A: These designators indicate different temperature grades. The "E" suffix specifies the extended temperature range (-40°C to 125°C), while the "I" suffix specifies the industrial temperature range (-40°C to 85°C).

Q: Are the pinouts identical between these parts?

A: Yes. Both parts use the 20-SSOP package with identical pinout and mechanical dimensions (0.209" width, 5.30mm).

Q: Does the substitute part have the same memory specifications?

A: Yes. Both parts feature 1.5KB OTP program memory (1K x 12 organization) and 25 x 8 RAM, with identical access and programming characteristics.

Q: What is the inventory status for the substitute part?

A: The PIC16C56-10I/SS is listed as Active with 1133 pieces in stock, compared to 694 pieces for the obsolete main part.

Q: Are compliance certifications identical?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, carry MSL rating 1 (Unlimited), and share identical ECCN and HTSUS classifications.
