Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCP2004-E/SN is determined by the following critical parameters that must remain constant or compatible:

Core Substitution Criteria:

• Protocol: LINbus
• Number of Drivers/Receivers: 1/1
• Duplex: Half
• Receiver Hysteresis: 175 mV
• Voltage - Supply: 6V ~ 27V (minimum overlap required)
• Operating Temperature: -40°C ~ 125°C (minimum overlap required)
• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

Substitution Categories:

Direct Packaging Equivalent: MCP2004T-E/SN differs only in packaging format (Tape & Reel vs. Tube) while maintaining identical electrical specifications and Active product status.

Manufacturer Recommended Substitute: ATA663211-GAQW is a Functional Safety (FuSa) series alternative with enhanced operating temperature range (-40°C ~ 150°C) and extended supply voltage (5V ~ 28V). Receiver hysteresis differs at 100 mV. MSL rating is 3 (168 Hours) versus 1 (Unlimited).

Manufacturer Recommended Substitute: MCP2003B-E/SN maintains identical electrical parameters with Active product status and specified data rate of 20kBaud. Supply voltage range is 5.5V ~ 30V.

Parametric Equivalents: MCP2003-E/SN, MCP2003A-E/SN, and MCP2004A-E/SN share identical core electrical specifications (175 mV hysteresis, 6V ~ 27V supply, -40°C ~ 125°C operating range) with Active or Last Time Buy status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Active Status: MCP2004T-E/SN is the primary direct replacement, offering identical electrical specifications and Active product status. The only difference is packaging format (Tape & Reel instead of Tube), which affects procurement and handling but not electrical performance.

For Extended Operating Temperature Range: ATA663211-GAQW extends the operating temperature to -40°C ~ 150°C and supply voltage to 5V ~ 28V, suitable for applications requiring enhanced thermal performance. This part carries Functional Safety (FuSa) series designation and MSL rating of 3 (168 Hours). Receiver hysteresis is specified at 100 mV rather than 175 mV.

For Parametric Equivalence with Active Status: MCP2003-E/SN and MCP2003A-E/SN maintain identical electrical specifications (175 mV hysteresis, 6V ~ 27V supply, -40°C ~ 125°C operating range) with Active product status. MCP2003B-E/SN offers expanded supply voltage range (5.5V ~ 30V) and specified data rate of 20kBaud with Active status.

For Last Time Buy Alternatives: MCP2004A-E/SN shares identical specifications with MCP2004-E/SN but carries Last Time Buy status. This part should not be selected for new designs requiring long-term availability.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status consistent with the original MCP2004-E/SN.

Frequently Asked Questions (FAQ)

Q: Can MCP2004T-E/SN replace MCP2004-E/SN in production designs?

A: Yes. MCP2004T-E/SN is electrically identical to MCP2004-E/SN with all core parameters matching (175 mV hysteresis, 6V ~ 27V supply, -40°C ~ 125°C operating range, 8-SOIC package). The only difference is packaging format: Tape & Reel versus Tube. Both are suitable for surface mount assembly. MCP2004T-E/SN has Active product status, making it the recommended choice for new procurement.

Q: What is the difference between MCP2003-E/SN and MCP2004-E/SN?

A: Both parts share identical electrical specifications: 1/1 half-duplex LINbus transceiver, 175 mV receiver hysteresis, 6V ~ 27V supply voltage, -40°C ~ 125°C operating temperature, and 8-SOIC package. The primary difference is product status: MCP2004-E/SN is Last Time Buy while MCP2003-E/SN is Active. For new designs, MCP2003-E/SN is the preferred selection.

Q: Is ATA663211-GAQW a direct substitute for MCP2004-E/SN?

A: ATA663211-GAQW is a functional alternative with enhanced specifications but not a direct substitute. It extends operating temperature to -40°C ~ 150°C and supply voltage to 5V ~ 28V. However, receiver hysteresis is specified at 100 mV instead of 175 mV. The part belongs to the Functional Safety (FuSa) series and carries MSL rating of 3 (168 Hours) versus 1 (Unlimited). Selection depends on application requirements for thermal performance and hysteresis tolerance.

Q: What does Last Time Buy status mean for MCP2004-E/SN?

A: Last Time Buy indicates the manufacturer has discontinued production and will not accept new orders after a specified cutoff date. Existing inventory may be available, but long-term supply is not guaranteed. For ongoing production requirements, migration to Active status parts such as MCP2004T-E/SN, MCP2003-E/SN, or MCP2003A-E/SN is necessary.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (MCP2004T-E/SN, ATA663211-GAQW, MCP2003B-E/SN, MCP2003-E/SN, MCP2003A-E/SN, MCP2004A-E/SN) maintain ROHS3 compliance and REACH Unaffected status consistent with the original MCP2004-E/SN.

Q: What is the significance of Moisture Sensitivity Level (MSL) rating?

A: MSL rating indicates moisture absorption limits and shelf life requirements. MCP2004-E/SN and most substitutes carry MSL 1 (Unlimited), meaning no moisture sensitivity restrictions. ATA663211-GAQW carries MSL 3 (168 Hours), requiring storage in controlled humidity conditions and limiting shelf life to 168 hours after moisture exposure. This affects handling and storage procedures but not electrical performance.

Q: Can MCP2003B-E/SN be used in place of MCP2004-E/SN?

A: MCP2003B-E/SN is compatible for most applications. It maintains the 1/1 half-duplex LINbus transceiver configuration and 8-SOIC package. Supply voltage range is expanded to 5.5V ~ 30V, and data rate is specified at 20kBaud. Operating temperature remains -40°C ~ 125°C. The part has Active status. Receiver hysteresis is not specified in the provided data, which may require verification for applications with strict hysteresis requirements.
