Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL28258FBZ is determined by strict alignment of the following core parameters:

Mandatory Matching Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Compatibility Constraints:

• Supply voltage range of the substitute must encompass or be compatible with the application's operating voltage
• Operating temperature range must satisfy the thermal requirements of the end application
• Moisture sensitivity level and compliance certifications must be suitable for the intended environment

The MCP6002T-I/SN from Microchip Technology meets all mandatory matching criteria and is classified as an active product with superior availability. This device maintains identical package geometry and pinout compatibility while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

ISL28258FBZ Selection Criteria: The ISL28258FBZ is suitable for applications where the specific electrical characteristics (0.1 V/µs slew rate, 200 kHz gain bandwidth product) are required and the operating temperature range extends to 125°C. This device is ROHS3 compliant and REACH unaffected. However, the obsolete product status limits long-term availability and supply chain reliability.

MCP6002T-I/SN Selection Criteria: The MCP6002T-I/SN is recommended for new designs and production continuity due to its active product status and significantly higher inventory availability (241,240 pieces versus 3,500 pieces). This device maintains identical package geometry and pinout compatibility. The MCP6002T-I/SN offers superior electrical performance with a 0.6 V/µs slew rate and 1 MHz gain bandwidth product. The device is ROHS3 compliant and REACH unaffected.

Compatibility Considerations: Applications operating at temperatures above 85°C require the ISL28258FBZ or alternative components rated to 125°C. Applications operating within the -40°C to 85°C range are fully compatible with the MCP6002T-I/SN. The MCP6002T-I/SN features improved moisture sensitivity (MSL 1 versus MSL 3), providing enhanced reliability in humid environments. Both devices support identical supply voltage ranges within their respective specifications, with the MCP6002T-I/SN offering extended minimum supply voltage capability (1.8 V versus 2.4 V).

Frequently Asked Questions (FAQ)

Q: Can the MCP6002T-I/SN directly replace the ISL28258FBZ in existing designs?

A: Direct replacement is possible for applications operating within the -40°C to 85°C temperature range. Both devices share identical 8-SOIC package geometry, pinout configuration, and rail-to-rail output characteristics. Electrical performance differences (slew rate and bandwidth) must be evaluated against circuit requirements. Applications requiring operation above 85°C require alternative components.

Q: What are the key electrical differences between these devices?

A: The MCP6002T-I/SN provides superior slew rate (0.6 V/µs versus 0.1 V/µs) and gain bandwidth product (1 MHz versus 200 kHz). The ISL28258FBZ offers lower supply current (68 µA versus 100 µA) and higher output current per channel (30 mA versus 23 mA). Input bias current and input offset voltage are comparable between devices.

Q: Are there supply voltage compatibility issues?

A: The MCP6002T-I/SN supports a lower minimum supply voltage (1.8 V versus 2.4 V) and a higher maximum supply voltage (6.0 V versus 5.5 V). Applications operating at 2.4 V to 5.5 V are compatible with both devices. Applications requiring operation below 2.4 V or above 5.5 V require device-specific evaluation.

Q: What is the significance of the moisture sensitivity level difference?

A: The ISL28258FBZ is rated MSL 3 (168 hours), while the MCP6002T-I/SN is rated MSL 1 (unlimited). MSL 1 indicates superior moisture resistance and reduced risk of moisture-induced failures during storage and handling. Applications in high-humidity environments benefit from the MCP6002T-I/SN's improved moisture sensitivity rating.

Q: How do the operating temperature ranges affect substitution?

A: The ISL28258FBZ operates from -40°C to 125°C, while the MCP6002T-I/SN operates from -40°C to 85°C. Substitution is valid only for applications with maximum operating temperatures at or below 85°C. High-temperature applications (85°C to 125°C) require the ISL28258FBZ or alternative components with equivalent temperature ratings.

Q: Are both devices RoHS and REACH compliant?

A: Both the ISL28258FBZ and MCP6002T-I/SN are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What packaging options are available for the MCP6002T-I/SN?

A: The MCP6002T-I/SN is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both manual and automated assembly processes.
