Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCA82C251T/YM,112 are identified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Protocol: CANbus
• Duplex Configuration: Half-duplex (1 driver, 1 receiver)
• Receiver Hysteresis: 150 mV
• Supply Voltage Range: 4.5V ~ 5.5V
• Operating Temperature Range: -40°C ~ 125°C
• Package Type: 8-SOIC surface mount
• Physical Dimensions: 0.154" width (3.90mm)

The L9616 from STMicroelectronics meets all critical electrical parameters and physical package requirements, qualifying it as a parametric equivalent. The L9616 is currently in active production status, providing supply continuity for the obsolete PCA82C251T/YM,112.

Parameter Comparison

Engineering Selection Recommendations

The L9616 (STMicroelectronics) is the direct parametric equivalent for the PCA82C251T/YM,112. Selection criteria are based on the following factors:

Electrical Compatibility: All critical electrical parameters match exactly, including supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 125°C), receiver hysteresis (150 mV), and CANbus half-duplex transceiver configuration (1/1 drivers/receivers).

Physical Compatibility: Both components use identical 8-SOIC surface mount packaging with 0.154" width (3.90mm), ensuring direct PCB footprint compatibility without layout modifications.

Compliance Status: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Supply Status: The L9616 is in active production, providing reliable long-term availability compared to the obsolete PCA82C251T/YM,112.

Frequently Asked Questions (FAQ)

Q: Can the L9616 be used as a direct replacement for the PCA82C251T/YM,112 on existing PCBs?

A: Yes. The L9616 matches all electrical parameters and uses the identical 8-SOIC package footprint. No PCB modifications are required for physical or electrical compatibility.

Q: Are there differences in moisture sensitivity between these parts?

A: The PCA82C251T/YM,112 has MSL 1 (unlimited moisture exposure), while the L9616 has MSL 3 (168 hours). This affects storage and handling procedures but does not impact functional performance after assembly.

Q: What is the primary reason to substitute the PCA82C251T/YM,112?

A: The PCA82C251T/YM,112 is obsolete. The L9616 provides equivalent functionality with active production status, ensuring supply chain continuity and long-term availability.

Q: Do both parts support the same CANbus data rates?

A: Both parts are half-duplex CANbus transceivers with identical electrical specifications. Data rate capability is determined by the CAN controller and network configuration, not the transceiver IC.

Q: Are there packaging differences between these parts?

A: Both use 8-SOIC surface mount packages with identical physical dimensions (0.154" width, 3.90mm). The L9616 is supplied in tube packaging, while the original part number does not specify packaging format.
