Substitute Part Grouping Explanation

Substitution for the PIC16LCE624-04E/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 Speed: 4MHz
• I/O Count: 13 pins
• Supply Voltage Range: 2.5V ~ 5.5V
• Package Type: 20-SSOP surface mount
• Peripheral Set: Brown-out Detect/Reset, POR, WDT

The substitute part PIC16LCE624-04I/SS maintains identical electrical and functional specifications with the exception of operating temperature range and product status. This part is actively manufactured and represents a direct functional equivalent.

Engineering Selection Recommendations

The PIC16LCE624-04I/SS serves as the active production equivalent to the obsolete PIC16LCE624-04E/SS. Both parts are ROHS3 compliant and share identical electrical specifications, memory architecture, and package footprint. The primary distinction is the operating temperature range: the -04E variant supports -40°C to 125°C, while the -04I variant operates from -40°C to 85°C.

Selection between these parts depends on application temperature requirements. For designs operating within the -40°C to 85°C range, the PIC16LCE624-04I/SS is the recommended choice due to its active product status and continued manufacturing availability. For applications requiring operation above 85°C, the -04E specification must be maintained, though sourcing may be limited due to obsolescence.

Both parts maintain identical pin configuration, electrical performance, and compliance certifications, ensuring direct substitution within the specified temperature operating window.

Frequently Asked Questions (FAQ)

Q: Can PIC16LCE624-04I/SS directly replace PIC16LCE624-04E/SS in existing designs?

A: Yes, provided the application operates within the -40°C to 85°C temperature range. Both parts share identical core specifications, memory configuration, I/O count, supply voltage range, and 20-SSOP package footprint. No circuit modifications are required.

Q: What is the key difference between these two part numbers?

A: The operating temperature range differs. The -04E supports -40°C to 125°C, while the -04I supports -40°C to 85°C. All other electrical and functional parameters are identical.

Q: Why is the PIC16LCE624-04E/SS listed as obsolete?

A: The -04E variant has been discontinued by Microchip Technology. The -04I variant remains in active production and is the recommended source for new designs and production continuity.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 20-SSOP surface mount package with 0.209" width and 5.30mm dimensions. Pinout and I/O configuration are identical.

Q: What compliance certifications apply to both parts?

A: Both the PIC16LCE624-04E/SS and PIC16LCE624-04I/SS are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.31.0001. Moisture sensitivity level is 1 (unlimited).
