PIC16LCE625-04E/SS Equivalent & Substitute Parts

Part Overview

The PIC16LCE625-04E/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 4.6KB OTP program memory, 128 bytes each of EEPROM and RAM, and 13 I/O pins. Designed for embedded applications requiring low-power operation across a wide supply voltage range (2.5V to 5.5V), this device integrates brown-out detection, power-on reset, and watchdog timer functionality.

The PIC16LCE625-04E/SS is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support legacy system maintenance or redesigns requiring active components with compatible electrical and mechanical characteristics.

Engineering Selection Recommendations

The PIC16LCE625-04I/SS is a direct functional equivalent to the PIC16LCE625-04E/SS. Both devices share identical electrical specifications, memory architecture, I/O configuration, and package form factor. The substitute part carries active product status from Microchip Technology, ensuring ongoing availability and supply chain support.

The operating temperature range difference (-40°C to 85°C for the substitute versus -40°C to 125°C for the main part) represents a narrower specification window. Applications operating within the -40°C to 85°C range encounter no compatibility constraints. Designs requiring operation above 85°C must retain the original part number or evaluate alternative solutions outside this product family.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, supporting equivalent handling and storage protocols. Selection between these parts should prioritize the active-status substitute for new designs and ongoing production to ensure long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can PIC16LCE625-04I/SS replace PIC16LCE625-04E/SS in existing designs?

A: Yes, for applications operating within -40°C to 85°C. The substitute part is electrically and mechanically identical across all specified parameters. If your design requires operation above 85°C, the original part number must be retained.

Q: What is the significance of the product status difference?

A: The main part (PIC16LCE625-04E/SS) is classified as obsolete, indicating Microchip Technology has discontinued active production and support. The substitute (PIC16LCE625-04I/SS) maintains active status, ensuring continued availability, technical support, and supply chain reliability for new and ongoing production.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 20-SSOP package with 0.209" width and 5.30mm body dimension. PCB footprints, assembly processes, and mechanical mounting are fully compatible.

Q: Do both parts support the same supply voltage range?

A: Yes. Both the PIC16LCE625-04E/SS and PIC16LCE625-04I/SS operate across 2.5V to 5.5V supply voltage, enabling direct substitution in power supply designs without modification.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance status and moisture sensitivity level (MSL 1, unlimited). Handling, storage, and environmental compliance requirements are equivalent.

Q: What memory specifications must match for substitution?

A: Program memory (4.6KB OTP), EEPROM (128 x 8), and RAM (128 x 8) must be identical. Both parts meet these requirements and are fully compatible.
