Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP2004A-E/SN is determined by the following critical parameters:

Primary Substitution Criteria:

• Protocol: LINbus
• Type: Transceiver
• Number of Drivers/Receivers: 1/1
• Duplex: Half
• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

Secondary Compatibility Parameters:

• Receiver Hysteresis: 175 mV (preferred match)
• Voltage - Supply: 6V ~ 27V (minimum acceptable range)
• Operating Temperature: -40°C ~ 125°C (minimum acceptable range)
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents – Parts that match all primary criteria and secondary parameters identically. These parts are direct functional replacements with identical electrical and mechanical specifications.

Category 2: Manufacturer Recommended Alternatives – Parts that match all primary criteria but may have extended operating temperature ranges, different receiver hysteresis values, or enhanced supply voltage ranges. These parts provide functional compatibility with potential performance enhancements.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended First Choice):

MCP2003-E/SN, MCP2003A-E/SN, and MCP2004-E/SN are parametric equivalents to the MCP2004A-E/SN. These parts maintain identical electrical specifications including receiver hysteresis (175 mV), supply voltage range (6V ~ 27V), and operating temperature range (-40°C ~ 125°C). All three parts are currently in Active product status, ensuring long-term availability and supply chain stability. These parts are suitable for direct substitution in applications where the MCP2004A-E/SN is specified.

Manufacturer Recommended Alternative:

MCP2003B-E/SN is designated as a manufacturer-recommended alternative. This part maintains the core LINbus transceiver functionality with 1/1 configuration and half-duplex operation in the 8-SOIC package. The MCP2003B-E/SN offers an extended supply voltage range (5.5V ~ 30V) compared to the main part, providing additional design flexibility for applications with lower minimum supply voltages. This part is in Active status with substantial inventory availability (6800 pcs).

Extended Temperature Range Alternative:

ATA663211-GAQW is a manufacturer-recommended alternative with an extended operating temperature range (-40°C ~ 150°C), providing 25°C additional high-temperature capability. This part features a lower receiver hysteresis value (100 mV) and an extended supply voltage range (5V ~ 28V). The ATA663211-GAQW is designated as part of the Functional Safety (FuSa) series and is in Active status. Selection of this part is appropriate for applications requiring enhanced temperature performance or functional safety compliance. Note that this part has MSL rating of 3 (168 Hours), requiring controlled moisture handling during storage and assembly.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the main part. Selection should prioritize parts in Active product status to ensure long-term supply availability and support.

Frequently Asked Questions (FAQ)

Q: Can MCP2003-E/SN be used as a direct replacement for MCP2004A-E/SN?

A: Yes. MCP2003-E/SN is a parametric equivalent with identical electrical specifications including receiver hysteresis (175 mV), supply voltage range (6V ~ 27V), and operating temperature range (-40°C ~ 125°C). Both parts use the 8-SOIC package and are LINbus half-duplex transceivers with 1/1 driver/receiver configuration. The part is currently in Active status, providing superior supply chain availability compared to the Last Time Buy status of MCP2004A-E/SN.

Q: What is the difference between MCP2003B-E/SN and MCP2003-E/SN?

A: MCP2003B-E/SN provides an extended supply voltage range (5.5V ~ 30V) compared to MCP2003-E/SN (6V ~ 27V). This allows operation at lower minimum supply voltages. Both parts maintain the same receiver hysteresis (175 mV), operating temperature range (-40°C ~ 125°C), and 8-SOIC package. MCP2003B-E/SN is suitable for applications requiring lower supply voltage operation.

Q: When should ATA663211-GAQW be selected instead of other substitutes?

A: ATA663211-GAQW should be selected when applications require extended high-temperature operation (-40°C ~ 150°C) or when functional safety compliance is required. This part is part of the Functional Safety (FuSa) series. The lower receiver hysteresis (100 mV) may provide improved noise immunity in certain applications. Note that this part requires MSL 3 moisture handling (168 hours), requiring controlled storage conditions.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All substitute parts listed are available in the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical and electrical compatibility with existing PCB designs and assembly processes.

Q: What is the significance of the Last Time Buy status for MCP2004A-E/SN?

A: Last Time Buy status indicates that the manufacturer has discontinued or will discontinue production of this part. Existing inventory may be limited. Transitioning to an Active status substitute part (MCP2003-E/SN, MCP2003A-E/SN, MCP2003B-E/SN, or ATA663211-GAQW) ensures long-term design support and supply chain continuity.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, consistent with the main part MCP2004A-E/SN.

Q: What is the difference in Moisture Sensitivity Level (MSL) between parts?

A: MCP2004A-E/SN, MCP2003-E/SN, MCP2003A-E/SN, MCP2003B-E/SN, and MCP2004-E/SN all have MSL 1 (Unlimited), allowing indefinite storage without moisture control. ATA663211-GAQW has MSL 3 (168 Hours), requiring that the part be used within 168 hours of exposure to ambient conditions above 30°C and 60% relative humidity, or be re-baked according to IPC standards. This affects handling and storage procedures during manufacturing.
