PCA82C250T/N,112 CANbus Transceiver Half Duplex - Equivalent & Substitute Parts

Part Overview

The PCA82C250T/N,112 is a half-duplex CANbus transceiver interface IC manufactured by NXP Semiconductors in an 8-SOIC surface mount package. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity. The part operates within a 4.5V to 5.5V supply range and supports industrial temperature specifications from -40°C to 125°C. Substitute parts must maintain compatibility with the half-duplex CANbus protocol, identical package geometry, and equivalent electrical performance characteristics.

Engineering Selection Recommendations

For Direct Replacement (Half-Duplex, Full Temperature Range):

MCP2551-E/SN and MCP2551T-E/SN are the primary substitutes, both manufactured by Microchip Technology with active product status. These parts maintain half-duplex operation, identical 4.5V to 5.5V supply range, and full -40°C to 125°C operating temperature specification. The difference between MCP2551-E/SN (tube packaging) and MCP2551T-E/SN (cut tape & Digi-Reel packaging) is packaging format only; electrical specifications are identical. Both are ROHS3 compliant with MSL 1 rating.

For Industrial Applications with Reduced Temperature Requirements:

MCP2551-I/SN and MCP2551T-I/SN provide active product status with identical electrical characteristics to the -E variants but operate to -40°C to 85°C. These are suitable for applications not requiring the full 125°C upper limit. SN65HVD230DR (Texas Instruments, active status) offers an alternative but operates at 3V to 3.6V supply range, requiring voltage level translation if the system uses 5V logic.

For Full-Duplex Capability (Functional Upgrade):

MAX13052 series parts (ASA+, ASA+T, ESA+, ESA+T) from Analog Devices Inc./Maxim Integrated provide full-duplex operation instead of half-duplex. These parts are active products with ROHS3 compliance. The ASA+ variants support -40°C to 125°C; ESA+ variants support -40°C to 85°C. Supply voltage range is 4.75V to 5.25V, which is narrower than the original part. Full-duplex operation requires circuit redesign and is not a direct pin-compatible replacement.

All substitute parts maintain 8-SOIC package geometry, surface mount mounting type, and MSL 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can MCP2551 parts directly replace the PCA82C250T/N,112 without circuit modification?

A: MCP2551-E/SN and MCP2551T-E/SN are pin-compatible half-duplex CANbus transceivers in identical 8-SOIC packages with matching voltage supply and temperature ranges. Direct PCB substitution is possible if the original design does not depend on specific hysteresis characteristics. The MCP2551 exhibits 200 mV receiver hysteresis versus 150 mV for the original part; this difference is within typical CANbus system tolerances.

Q: What is the difference between MCP2551-E/SN and MCP2551T-E/SN?

A: Both parts have identical electrical specifications and operating ranges. The difference is packaging format: MCP2551-E/SN is supplied in tube packaging, while MCP2551T-E/SN is supplied in cut tape and Digi-Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Why do SN65HVD230 parts have a different voltage supply range (3V ~ 3.6V)?

A: SN65HVD230 transceivers are designed for 3.3V logic systems, not 5V systems. Direct substitution requires voltage level translation circuitry or a redesigned power supply. These parts are not recommended as direct replacements for 5V-based designs.

Q: Can MAX13052 full-duplex parts replace the half-duplex PCA82C250T/N,112?

A: MAX13052 parts are not direct replacements. Full-duplex operation requires different circuit topology and signal routing compared to half-duplex designs. Additionally, the supply voltage range (4.75V ~ 5.25V) is narrower than the original part (4.5V ~ 5.5V). Full-duplex substitution requires complete circuit redesign and is not a pin-compatible solution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the original part's compliance status.

Q: Which substitute offers the best inventory availability?

A: MCP2551T-I/SN has the highest inventory level at 158,355 pieces in stock. MCP2551T-E/SN has 24,254 pieces available. Both are active products from Microchip Technology with established supply chains.
