Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16CE624-20E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 1.75KB OTP program memory, 128 x 8 EEPROM, 96 x 8 RAM
• Operating Frequency: 20MHz
• I/O Count: 13 pins
• Supply Voltage Range: 3V ~ 5.5V
• Package Type: 20-SSOP surface mount
• Compliance: ROHS3 Compliant

The identified substitute part PIC16CE624-20I/SS maintains identical electrical and mechanical specifications with the exception of product status (Active vs. Obsolete) and operating temperature range variance.

Parameter Comparison

Engineering Selection Recommendations

The PIC16CE624-20I/SS is the direct functional equivalent of the PIC16CE624-20E/SS. Both parts share identical electrical specifications, memory architecture, and package geometry. The primary distinction is product lifecycle status: the -20E/SS variant is obsolete, while the -20I/SS variant is active and currently manufactured.

For applications requiring the extended temperature range of -40°C to 125°C, the operating temperature specification of the -20I/SS (-40°C to 85°C) represents a narrower operational envelope. Applications operating within the -40°C to 85°C range encounter no thermal limitations with the substitute part.

Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can PIC16CE624-20I/SS directly replace PIC16CE624-20E/SS in existing designs?

A: Yes, for applications operating within -40°C to 85°C. The electrical specifications, memory configuration, I/O count, and package footprint are identical. Applications requiring operation above 85°C require thermal analysis against the -20E/SS extended range.

Q: What is the significance of the -20E and -20I designations?

A: The suffix indicates temperature grade and product status. The -20E/SS is an obsolete variant, while -20I/SS is an active production part. Both operate at 20MHz with identical core specifications.

Q: Are the 20-SSOP packages mechanically interchangeable?

A: Yes. Both parts use the 20-SSOP package with 0.209" width and 5.30mm dimensions, ensuring identical PCB footprints and assembly compatibility.

Q: What inventory considerations apply to these parts?

A: The PIC16CE624-20E/SS (701 pcs) is obsolete stock. The PIC16CE624-20I/SS (2200 pcs) is active production inventory, providing greater availability for new orders and long-term supply continuity.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications.
