Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16CE623T-04I/SO is determined by strict alignment of the following critical parameters:

• Core processor architecture (PIC 8-bit)
• Program memory capacity (896B OTP)
• EEPROM and RAM configuration (128 x 8 and 96 x 8 respectively)
• I/O pin count (13)
• Supply voltage range (3V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type and physical dimensions (18-SOIC)
• Peripheral feature set (Brown-out Detect/Reset, POR, WDT)

The PIC16CE623-04I/SO meets all substitution criteria as a direct equivalent, differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The PIC16CE623-04I/SO is a direct functional equivalent to the PIC16CE623T-04I/SO. Both devices share identical electrical specifications, memory configurations, I/O architecture, and package geometry. The primary distinction lies in product lifecycle status: the PIC16CE623T-04I/SO is obsolete, while the PIC16CE623-04I/SO maintains active status with verified programmability.

Selection between these parts should consider compliance requirements. The PIC16CE623T-04I/SO carries ROHS3 compliance certification, whereas the PIC16CE623-04I/SO is RoHS non-compliant. For applications subject to RoHS directives, the PIC16CE623T-04I/SO remains the appropriate choice despite obsolescence. For applications without RoHS constraints, the PIC16CE623-04I/SO offers the advantage of active product support and verified programmability through DiGi-Electronics.

Frequently Asked Questions (FAQ)

Q: Can PIC16CE623-04I/SO replace PIC16CE623T-04I/SO in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters. Pin configuration, memory architecture, I/O count, voltage requirements, and thermal operating range are equivalent. Direct substitution is possible without circuit modification.

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

A: The parts differ in product status and compliance certification. PIC16CE623T-04I/SO is obsolete and ROHS3 compliant. PIC16CE623-04I/SO is active and RoHS non-compliant. Functionally, they are identical.

Q: Are there package compatibility concerns?

A: No. Both devices use the 18-SOIC package with identical physical dimensions (0.295", 7.50mm width). PCB footprints and assembly processes are interchangeable.

Q: Which part should be selected for new designs?

A: For new designs without RoHS compliance requirements, PIC16CE623-04I/SO is preferred due to active product status. For applications requiring RoHS3 compliance, PIC16CE623T-04I/SO remains available despite obsolescence classification.

Q: Are memory specifications identical between these parts?

A: Yes. Both devices feature 896B OTP program memory (512 x 14), 128 x 8 EEPROM, and 96 x 8 RAM. Memory organization, access timing, and functionality are equivalent.
