Substitute Part Grouping Explanation

Substitution of the PIC16LCE623T-04E/SS is determined by strict alignment of the following critical parameters:

Manufacturer & Series: Microchip Technology PIC® 16C family
Core Architecture: 8-Bit PIC processor
Memory Configuration: 896B OTP program memory, 128 x 8 EEPROM, 96 x 8 RAM
Clock Speed: 4MHz operation
I/O Count: 13 I/O 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 PIC16LCE623-04I/SS maintains identical electrical specifications, memory architecture, I/O configuration, and package form factor. Differences in product status (active vs. obsolete), operating temperature range, and packaging format (tube vs. standard) do not affect functional substitution in applications designed for the original part.

Engineering Selection Recommendations

The PIC16LCE623-04I/SS is a direct functional substitute for the PIC16LCE623T-04E/SS based on identical core electrical specifications, memory architecture, and package form factor. The substitute part carries active product status from Microchip Technology, ensuring ongoing availability and manufacturing support compared to the obsolete original part.

The operating temperature range of the substitute (-40°C to 85°C) is narrower than the original (-40°C to 125°C). Applications requiring operation above 85°C must evaluate this limitation against system thermal requirements.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), supporting equivalent environmental and regulatory requirements. The substitute is available in tube packaging, which may differ from original procurement specifications but does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can PIC16LCE623-04I/SS replace PIC16LCE623T-04E/SS in existing designs?

A: Yes. Both parts share identical core processor architecture, memory configuration, I/O count, supply voltage range, clock speed, and 20-SSOP package dimensions. Functional substitution is direct for applications operating within the substitute's temperature range (-40°C to 85°C).

Q: What is the key difference between these parts?

A: The primary differences are product status (obsolete vs. active), operating temperature range (125°C vs. 85°C maximum), and packaging format (standard vs. tube). Electrical and mechanical specifications are identical.

Q: Does the narrower temperature range of the substitute affect compatibility?

A: The substitute operates to 85°C maximum, compared to 125°C for the original. Applications requiring sustained operation above 85°C must evaluate thermal performance against system requirements. Most commercial and industrial applications operate within this range.

Q: Are the 20-SSOP packages identical between both parts?

A: Yes. Both parts use 20-SSOP (0.209", 5.30mm Width) surface mount packages with identical pinout and mechanical dimensions. PCB layout and footprints are directly compatible.

Q: What is the inventory status of each part?

A: PIC16LCE623T-04E/SS (obsolete) has 788 pieces in stock. PIC16LCE623-04I/SS (active) has 1065 pieces in stock. The active substitute offers better long-term availability.

Q: Are both parts RoHS compliant?

A: Yes. Both PIC16LCE623T-04E/SS and PIC16LCE623-04I/SS are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), meeting equivalent environmental and regulatory standards.
