PIC16LC925T-I/L Equivalent & Substitute Parts

Part Overview

The PIC16LC925T-I/L is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 7KB OTP program memory, 176 x 8 bytes of RAM, and 25 I/O pins in a 68-PLCC package. The device operates at 20MHz with a supply voltage range of 2.5V to 5.5V and includes integrated peripherals such as PWM, LCD driver, brown-out detection, and watchdog timer functionality.

The PIC16LC925T-I/L is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design flexibility is required for new production runs. Substitute parts must maintain identical electrical characteristics, memory configuration, pin count, and package specifications to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC925T-I/L is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: PIC
• Memory Configuration: 7KB (4K x 14) OTP program memory and 176 x 8 RAM
• I/O Pin Count: 25 pins
• Operating Frequency: 20MHz
• Supply Voltage Range: 2.5V ~ 5.5V
• Package Type: 68-PLCC (68-LCC J-Lead)
• Peripheral Set: Identical I2C, SPI, PWM, LCD, brown-out detection, POR, and WDT functionality
• Data Converter Specification: A/D 5x10b
• Temperature Range: -40°C ~ 85°C

Only components matching all specified parameters qualify as direct substitutes. Variations in any parameter disqualify a part from this equivalence group.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC925-I/L qualifies as a direct substitute for the PIC16LC925T-I/L based on complete parameter equivalence. Both components are manufactured by Microchip Technology and share identical electrical specifications, memory architecture, I/O configuration, and peripheral functionality.

The primary distinction is product status: the PIC16LC925T-I/L is classified as obsolete, while the PIC16LC925-I/L maintains active status. This status difference reflects manufacturing availability and supply chain continuity. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical regulatory classifications (EAR99, HTSUS 8542.31.0001).

Selection of the PIC16LC925-I/L is appropriate for applications requiring the PIC16LC925T-I/L specification where component availability is a consideration. No circuit modifications, firmware adjustments, or design changes are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the PIC16LC925-I/L replace the PIC16LC925T-I/L in existing designs?

A: Yes. Both components are electrically and mechanically identical across all specified parameters. Direct substitution is possible without circuit redesign or firmware modification.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates manufacturing and supply chain availability. The PIC16LC925-I/L's active status means it remains in current production and is available through standard distribution channels. The PIC16LC925T-I/L's obsolete status indicates it is no longer manufactured. For new production runs or long-term supply assurance, the active part is preferred.

Q: Are there packaging differences between these parts?

A: No. Both components use identical 68-PLCC packaging (68-LCC J-Lead, 24.23x24.23mm). The only packaging difference is the supplier device package designation, which reflects distribution format (tube vs. other methods) and does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the PIC16LC925T-I/L and PIC16LC925-I/L are ROHS3 compliant, REACH unaffected, and classified under identical regulatory codes (EAR99, HTSUS 8542.31.0001). Moisture sensitivity level (MSL 3, 168 hours) is identical for both parts.

Q: What are the critical parameters that must match for substitution?

A: Core processor (PIC), core size (8-Bit), speed (20MHz), program memory (7KB OTP), RAM (176 x 8), I/O count (25), supply voltage (2.5V ~ 5.5V), data converters (A/D 5x10b), connectivity (I2C, SPI), peripherals (brown-out detect, LCD, POR, PWM, WDT), operating temperature (-40°C ~ 85°C), and package type (68-PLCC) must all remain constant.
