Substitute Part Grouping Explanation

Substitute parts for the PIC16LC717T-E/SS are identified based on strict electrical and mechanical parameter matching within the PIC® 16C microcontroller family. The substitution logic is based on the following critical parameters:

Core electrical specifications: 8-bit architecture, 20MHz operation, 4.6KB OTP program memory, 256 x 8 RAM, 2.5V to 5.5V supply voltage range, and 6-channel 10-bit A/D converter.

Peripheral feature set: Brown-out detect/reset, power-on reset (POR), PWM, and watchdog timer functionality.

Physical compatibility: 20-SSOP surface mount package with 0.209" width and 5.30mm dimensions.

Connectivity standards: I2C and SPI interfaces.

The substitute parts listed maintain identical electrical and mechanical specifications, ensuring direct functional replacement in existing circuit designs. Differences in product status and operating temperature ranges are noted for design consideration but do not affect core substitutability.

Parameter Comparison

Engineering Selection Recommendations

PIC16LC717-E/SS is the primary substitute for the obsolete PIC16LC717T-E/SS. This part maintains identical electrical and mechanical specifications while offering active product status and verified programmability. The extended operating temperature range of -40°C to 125°C matches the original part, providing full thermal compatibility. ROHS3 compliance and unlimited moisture sensitivity rating ensure regulatory and environmental consistency.

PIC16LC717-I/SS serves as an alternative substitute with identical core electrical and mechanical parameters. This part differs in operating temperature range, limited to -40°C to 85°C, which restricts its use to applications not requiring the full extended temperature capability of the original part. Verified programmability and active product status support production continuity.

Both substitute parts are packaged in 20-SSOP format with identical pinout and footprint compatibility, enabling direct board-level replacement without layout modifications. Selection between PIC16LC717-E/SS and PIC16LC717-I/SS depends on application temperature requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can PIC16LC717-E/SS directly replace PIC16LC717T-E/SS in existing designs?

A: Yes. Both parts share identical electrical specifications, memory configuration, peripheral features, and 20-SSOP package dimensions. Direct substitution is supported without circuit modifications.

Q: What is the difference between PIC16LC717-E/SS and PIC16LC717-I/SS?

A: The primary difference is operating temperature range. PIC16LC717-E/SS operates from -40°C to 125°C, while PIC16LC717-I/SS operates from -40°C to 85°C. All other electrical and mechanical parameters are identical. Selection depends on application temperature requirements.

Q: Why is the original PIC16LC717T-E/SS classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. Active equivalents PIC16LC717-E/SS and PIC16LC717-I/SS provide continued design support and supply availability.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both PIC16LC717-E/SS and PIC16LC717-I/SS are ROHS3 compliant, matching the regulatory status of the original part.

Q: What packaging options are available for these substitutes?

A: Both substitute parts are supplied in 20-SSOP surface mount packages. Tube packaging is standard for both alternatives.

Q: Is programmability verified for the substitute parts?

A: Yes. Both PIC16LC717-E/SS and PIC16LC717-I/SS have verified programmability status, confirming production readiness and functional validation.
