Engineering Selection Recommendations

The PIC16C58B-04I/SS qualifies as a direct functional substitute for the PIC16C58BT-04E/SS based on complete alignment of electrical specifications, memory configuration, I/O architecture, and package form factor. The substitute part carries active product status from Microchip Technology, ensuring ongoing availability and manufacturing support.

Key considerations for selection:

Operating Temperature Differential: The substitute part specifies an operating temperature range of -40°C to 85°C, compared to the main part's -40°C to 125°C range. Applications requiring operation above 85°C require thermal analysis to confirm the substitute's suitability.

Product Status: The substitute's active status provides supply chain continuity and eliminates obsolescence risk associated with the main part's discontinued status.

Compliance Certifications: Both parts maintain ROHS3 compliance and identical REACH and ECCN classifications, supporting regulatory requirements without modification.

Programmability Verification: The substitute part is verified as programmable through DiGi-Electronics, confirming functional programming capability for OTP deployment.

Frequently Asked Questions (FAQ)

Q: Can PIC16C58B-04I/SS directly replace PIC16C58BT-04E/SS in existing designs?

A: Yes, for applications operating within the -40°C to 85°C temperature range. The substitute maintains identical electrical specifications, memory architecture, I/O configuration, and 20-SSOP package dimensions. No circuit modifications are required for functional replacement.

Q: What is the primary difference between these two parts?

A: The main differences are product status (obsolete vs. active) and operating temperature range. The substitute specifies -40°C to 85°C maximum, while the original extends to 125°C. Both parts are electrically and mechanically identical across all other parameters.

Q: Are there packaging differences between these parts?

A: No. Both parts use identical 20-SSOP surface mount packaging with 0.209" width and 5.30mm dimensions. PCB footprints and assembly processes remain unchanged.

Q: Does the substitute part support OTP programming?

A: Yes. The PIC16C58B-04I/SS is verified as programmable and maintains OTP (One-Time Programmable) memory type identical to the original part.

Q: What supply voltage range do these parts support?

A: Both parts operate across 3V to 5.5V supply voltage range, supporting single-supply and dual-supply configurations within this specification.

Q: Are compliance certifications identical?

A: Yes. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Moisture sensitivity level is 1 (unlimited) for both parts.
