PIC16CE623-20E/SO Equivalent & Substitute Parts

Part Overview

The PIC16CE623-20E/SO is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 896B of OTP (One-Time Programmable) memory and 13 I/O pins in an 18-SOIC surface mount package. This device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, redesigns, and production continuity. The primary challenge in sourcing this component stems from its discontinued status and the need to identify active alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16CE623-20E/SO is determined by strict alignment across the following critical parameters:

Core Electrical Compatibility:

• Identical core processor architecture (PIC)
• Matching core size (8-Bit)
• Identical clock speed (20MHz)
• Identical program memory capacity (896B / 512 x 14)
• Identical program memory type (OTP)
• Matching I/O pin count (13)
• Overlapping or equivalent voltage supply range (3V ~ 5.5V)

Mechanical Compatibility:

• Identical package type (18-SOIC)
• Identical package dimensions (0.295", 7.50mm Width)
• Surface mount mounting type

Compliance & Certification:

• RoHS3 compliance maintained
• Moisture Sensitivity Level (MSL) compatibility

Substitute parts must satisfy all electrical and mechanical criteria simultaneously. Temperature range variations are permissible only when the substitute range encompasses or exceeds the original specification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16CE623-20I/SO qualifies as a direct substitute for the PIC16CE623-20E/SO based on complete electrical and mechanical parameter alignment. The substitute part maintains active product status with Microchip Technology, ensuring ongoing availability and support.

The primary distinction between these parts is the operating temperature range: the main part specifies -40°C ~ 125°C, while the substitute specifies -40°C ~ 85°C. For applications operating within the -40°C ~ 85°C envelope, the PIC16CE623-20I/SO provides full functional equivalence with the added benefit of active product status and verified programmability.

Applications requiring operation above 85°C must retain the original PIC16CE623-20E/SO specification or identify alternative solutions outside the direct substitute category. All other electrical, mechanical, and compliance parameters are identical between the two parts.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between PIC16CE623-20E/SO and PIC16CE623-20I/SO?

A: The parts are electrically and mechanically identical. The main difference is the operating temperature range: the -20E variant supports -40°C ~ 125°C, while the -20I variant supports -40°C ~ 85°C. The -20I is currently active in production, whereas the -20E is obsolete.

Q: Can PIC16CE623-20I/SO be used in applications designed for PIC16CE623-20E/SO?

A: Yes, provided the application's maximum operating temperature does not exceed 85°C. If your system operates within this temperature range, the -20I variant is a direct substitute with identical electrical performance and pin compatibility.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 18-SOIC package with dimensions of 0.295" × 7.50mm width. PCB footprints and assembly processes are identical.

Q: What does the suffix "-20E" and "-20I" indicate?

A: The "-20" indicates the 20MHz clock speed. The "E" and "I" suffixes denote different temperature grades: "E" represents the extended temperature range (-40°C ~ 125°C), while "I" represents the industrial temperature range (-40°C ~ 85°C).

Q: Are both parts RoHS compliant?

A: Yes. Both PIC16CE623-20E/SO and PIC16CE623-20I/SO are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Why is the -20E variant listed as obsolete?

A: Microchip Technology has discontinued the extended temperature variant in favor of the industrial temperature variant. The -20I remains in active production and is the recommended choice for new designs and ongoing production support.
