Substitute Part Grouping Explanation

Substitution of the PIC16C62B-20E/SS is determined by strict equivalence across the following critical parameters:

  • Core Architecture: PIC 8-bit processor
  • Memory Configuration: 4.6KB OTP program memory, 128 x 8 RAM
  • Clock Speed: 20MHz operation
  • I/O Count: 22 I/O pins
  • Supply Voltage: 4V ~ 5.5V range
  • Package Format: 28-SSOP surface mount
  • Peripheral Set: I2C, SPI, PWM, WDT, brown-out detection

The PIC16C62B-20I/SS qualifies as a direct substitute based on identical electrical specifications and package configuration. Differences in product status and operating temperature range do not affect functional substitutability for applications within the specified temperature window.

Engineering Selection Recommendations

The PIC16C62B-20I/SS is a direct functional equivalent to the PIC16C62B-20E/SS. Selection between these parts should be based on the following factors:

Product Status: The PIC16C62B-20I/SS carries Active status, ensuring continued manufacturer support, availability, and compliance updates. The main part's Obsolete classification limits long-term supply assurance.

Compliance & Certifications: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and handling requirements.

Operating Temperature Range: The substitute part operates within -40°C to 85°C, which is narrower than the main part's -40°C to 125°C range. Selection should confirm that application requirements fall within the -40°C to 85°C window.

Packaging & Availability: Both parts use identical 28-SSOP packaging. The substitute part is available in Tube packaging format.

For applications requiring operation above 85°C, the main part remains the only specified option. For all other applications, the PIC16C62B-20I/SS is the recommended selection due to active product status and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the PIC16C62B-20I/SS replace the PIC16C62B-20E/SS in existing designs?

A: Yes, the PIC16C62B-20I/SS is a direct functional substitute. Both parts share identical core architecture, memory configuration, clock speed, I/O count, supply voltage range, and peripheral set. Pin-for-pin compatibility is maintained in the 28-SSOP package.

Q: What is the difference between the operating temperature ranges?

A: The main part operates from -40°C to 125°C, while the substitute operates from -40°C to 85°C. If your application requires operation above 85°C, the main part is necessary. For standard industrial and commercial temperature ranges, the substitute is fully compatible.

Q: Are there any differences in compliance or certifications?

A: Both parts are ROHS3 compliant with identical MSL ratings of 1 (Unlimited). No compliance differences exist between the two parts.

Q: Why is the main part classified as Obsolete?

A: Obsolete status indicates that Microchip Technology has discontinued active production and support for the PIC16C62B-20E/SS. The PIC16C62B-20I/SS remains in active production, making it the preferred choice for new designs and ongoing production support.

Q: Are the packages identical?

A: Yes, both parts use the 28-SSOP package with identical dimensions (0.209", 5.30mm Width). No PCB layout modifications are required for substitution.

Q: What packaging formats are available for each part?

A: The main part (PIC16C62B-20E/SS) is available in standard packaging. The substitute (PIC16C62B-20I/SS) is available in Tube packaging format.
