Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC620-04E/P is determined by strict alignment across the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating frequency (4MHz)
• Program memory capacity and type (896B OTP)
• RAM capacity (80 x 8)
• I/O pin count (13)
• Supply voltage range (2.5V ~ 6V)
• Peripheral feature set (Brown-out Detect/Reset, POR, WDT)
• Package form factor (18-DIP)
• Mounting technology (Through Hole)

The PIC16LC620-04I/P qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC620-04I/P serves as the direct functional equivalent for the obsolete PIC16LC620-04E/P. Both devices maintain identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and software interchangeability within the same application context.

The primary distinction between these parts is product lifecycle status: the PIC16LC620-04E/P is obsolete, while the PIC16LC620-04I/P remains in active production. This status difference, combined with the PIC16LC620-04I/P's ROHS3 compliance and verified programmability certification, positions it as the appropriate selection for new designs and legacy system replacements.

The operating temperature range of the PIC16LC620-04I/P (-40°C ~ 85°C) is narrower than the main part (-40°C ~ 125°C). Applications requiring operation above 85°C must evaluate this constraint against system thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the PIC16LC620-04I/P directly replace the PIC16LC620-04E/P in existing designs?

A: Yes. Both devices share identical core processor architecture, memory configuration, I/O count, supply voltage range, and 18-DIP package form factor. Pin assignments and functional behavior are equivalent, enabling direct substitution without circuit modification.

Q: What is the significance of the operating temperature range difference?

A: The PIC16LC620-04E/P operates from -40°C to 125°C, while the PIC16LC620-04I/P operates from -40°C to 85°C. Applications requiring sustained operation above 85°C must confirm that the narrower range of the substitute part meets system thermal specifications.

Q: Why is the PIC16LC620-04E/P classified as obsolete?

A: Obsolescence reflects Microchip Technology's discontinuation of this product line. The PIC16LC620-04I/P remains in active production and represents the current equivalent offering for this microcontroller class.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry ROHS3 compliance and REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS 8542.31.0001. Both have MSL rating of 1 (Unlimited). Programmability verification is confirmed for both devices.

Q: What packaging considerations apply to these devices?

A: Both parts use 18-DIP (0.300", 7.62mm) through-hole packaging. PCB footprint, lead spacing, and insertion requirements are identical, eliminating any mechanical redesign requirements.
