Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C58B-04E/SS is determined by strict alignment of the following critical parameters:

• Core Processor & Architecture: Must be PIC processor family
• Core Size: Must be 8-Bit
• Program Memory: Must be 3KB (2K x 12) OTP type
• RAM Configuration: Must be 73 x 8 bytes
• I/O Count: Must provide 12 I/O pins
• Speed: Must support 4MHz operation
• Supply Voltage: Must support 3V ~ 5.5V range
• Peripherals: Must include POR and WDT
• Package: Must be 20-SSOP form factor
• Mounting Type: Must be Surface Mount

The identified substitute part PIC16C58B-04I/SS meets all critical electrical and mechanical parameters. The primary distinction is the operating temperature range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C58B-04I/SS is a direct functional substitute for the PIC16C58B-04E/SS. Both devices share identical electrical specifications, memory configuration, I/O architecture, and package form factor. The substitute part carries Active product status, ensuring ongoing availability and supply chain support compared to the Obsolete classification of the main part.

The operating temperature range of the substitute part is narrower (-40°C ~ 85°C versus -40°C ~ 125°C). Applications requiring operation above 85°C must retain the original PIC16C58B-04E/SS or evaluate alternative device families. For standard industrial and commercial temperature ranges, the PIC16C58B-04I/SS provides equivalent performance with superior supply availability.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can PIC16C58B-04I/SS replace PIC16C58B-04E/SS in all applications?

A: Yes, for applications operating within the -40°C to 85°C temperature range. The electrical specifications, memory architecture, I/O configuration, and package form factor are identical. Applications requiring operation above 85°C require the original part or alternative device evaluation.

Q: What is the primary advantage of using PIC16C58B-04I/SS?

A: The substitute part carries Active product status, ensuring continued manufacturing and supply chain availability. The original PIC16C58B-04E/SS is Obsolete, making long-term sourcing difficult.

Q: Are there packaging differences between these parts?

A: Both parts use the 20-SSOP surface mount package with identical dimensions (0.209", 5.30mm Width). The main part is supplied without specified packaging, while the substitute is supplied in Tube packaging. This does not affect electrical or mechanical compatibility.

Q: Do both parts require the same PCB layout and design considerations?

A: Yes. Identical pin configuration, package footprint, and electrical characteristics ensure direct PCB compatibility without redesign.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. Compliance documentation is equivalent for manufacturing and environmental standards.
