MCP6285-E/P Equivalent & Substitute Parts

Part Overview

The MCP6285-E/P is a general purpose operational amplifier manufactured by Microchip Technology, featuring dual circuits in an 8-PDIP through-hole package. This device operates across a supply voltage range of 2.2V to 5.5V with rail-to-rail output capability and is rated for -40°C to 125°C operating temperature. The part is currently in active production status with 2600 units in stock.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain disruptions, or end-of-life considerations for the primary component. The MCP6285-E/P maintains compatibility with several equivalent dual-channel amplifier solutions that share identical package geometry and functional pin configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MCP6285-E/P is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin configuration to ensure direct socket replacement without PCB modification.

Functional Requirements: Dual-channel amplifier configuration with rail-to-rail output capability is mandatory. All substitutes maintain two independent amplifier circuits within a single 8-pin package.

Electrical Operating Range: Supply voltage compatibility spans the overlap of all candidate parts. The MCP6285-E/P operates from 2.2V to 5.5V; substitute parts must support operation within this range or a compatible subset.

Temperature Rating: Operating temperature range determines application suitability. The MCP6285-E/P covers -40°C to 125°C; substitutes with narrower temperature ranges are applicable only to designs operating within those constraints.

Performance Characteristics: Slew rate, gain bandwidth product, input bias current, and input offset voltage define signal fidelity. Substitutes with equal or superior performance characteristics maintain functional equivalence.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are required for equivalent parts in regulated applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - MCP6285-E/P: Recommended for new designs and applications requiring active production status with extended temperature range (-40°C to 125°C). This part offers the highest slew rate (2.5V/µs) and gain bandwidth product (5 MHz) among the candidate group, supporting higher-frequency signal processing applications.

Extended Temperature Range Substitute - TLV2472IP: Suitable for designs requiring CMOS amplifier characteristics with full industrial temperature range (-40°C to 125°C). This part maintains RoHS3 compliance and active product status. The TLV2472IP exhibits lower input offset voltage (0.25 mV) compared to the primary part, beneficial for precision measurement applications. Supply voltage range extends to 6V maximum.

Extended Temperature Range Substitute - TLV4112IP: Applicable for applications requiring general purpose amplifier topology with full industrial temperature range (-40°C to 125°C). This part provides significantly higher output current capability (320 mA per channel) compared to the primary part (25 mA), enabling direct drive of higher-impedance loads. RoHS3 compliant with active production status. Note: Product status is Last Time Buy, indicating limited future availability.

Constrained Temperature Range Substitutes - TLV2472CP and TLV4112CP: These variants operate within 0°C to 70°C temperature range and are applicable only to commercial-grade applications within this thermal envelope. Both maintain RoHS3 compliance. TLV4112CP is designated Last Time Buy status.

CMOS Alternative - OPA2337PA: Provides CMOS amplifier topology with superior input bias current (0.2 pA) and input offset voltage (0.5 mV). Operating temperature range is -40°C to 85°C, limiting use in applications requiring full -40°C to 125°C coverage. RoHS status not specified in available data. Output current per channel (9 mA) is lower than the primary part.

Compliance Verification: All recommended substitutes maintain REACH unaffected status and EAR99 export classification consistent with the primary part. RoHS3 compliance is confirmed for all Texas Instruments and Microchip variants.

Frequently Asked Questions (FAQ)

Q: Can TLV2472CP be used in place of MCP6285-E/P in all applications?

A: TLV2472CP is functionally compatible for socket replacement in applications operating within 0°C to 70°C temperature range. Applications requiring -40°C to 125°C operation must use TLV2472IP instead. Both parts share identical package geometry and pin configuration.

Q: What is the primary difference between TLV2472IP and TLV4112IP?

A: Both parts operate across -40°C to 125°C and use 8-DIP packaging. TLV2472IP is a CMOS amplifier with 2.8 MHz bandwidth and 35 mA output current per channel. TLV4112IP is a general purpose amplifier with 2.7 MHz bandwidth and 320 mA output current per channel. TLV4112IP is designated Last Time Buy status. Select TLV4112IP for applications requiring high output current drive capability.

Q: Is OPA2337PA a direct replacement for MCP6285-E/P?

A: OPA2337PA provides socket-compatible replacement with 8-DIP package and dual-channel configuration. However, operating temperature range is limited to -40°C to 85°C, restricting use to applications not requiring 125°C operation. Input bias current is superior (0.2 pA vs. 1 pA), but output current per channel is lower (9 mA vs. 25 mA).

Q: Why do some substitute parts show Last Time Buy status?

A: TLV4112CP and TLV4112IP are designated Last Time Buy, indicating the manufacturer has announced end-of-production. These parts remain available for current orders but future availability is limited. For new designs, select actively produced alternatives such as TLV2472IP or MCP6285-E/P.

Q: What supply voltage range is common to all substitute parts?

A: The overlapping supply voltage range across all candidates is 2.7V to 5.5V. The MCP6285-E/P extends to 2.2V minimum, while TLV series parts extend to 6V maximum. Verify specific application supply voltage requirements against individual part specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Texas Instruments and Microchip variants (TLV2472CP, TLV2472IP, TLV4112CP, TLV4112IP, MCP6285-E/P) are confirmed ROHS3 compliant. OPA2337PA RoHS status is not specified in available documentation.

Q: Which substitute part offers the lowest input offset voltage?

A: TLV4112IP and TLV4112CP both specify 0.175 mV input offset voltage, the lowest among all candidates. This characteristic is beneficial for precision analog signal conditioning applications requiring minimal DC error.

Q: Can I use OPA2337PA in a -40°C to 125°C application?

A: No. OPA2337PA operating temperature range is -40°C to 85°C. Applications requiring operation at temperatures above 85°C must use MCP6285-E/P, TLV2472IP, or TLV4112IP instead.
