MCP616T-I/MS Equivalent & Substitute Parts

Part Overview

The MCP616T-I/MS is a general purpose operational amplifier manufactured by Microchip Technology, housed in an 8-MSOP surface mount package. This device is classified as a rail-to-rail output amplifier with a single circuit configuration, designed for low-power applications requiring compact form factors. The part is currently in active production status with 2,750 units available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within the specified parameter ranges for this amplifier category. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or when alternative sourcing strategies are required for production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP616T-I/MS is determined by the following critical parameters:

Mechanical Compatibility:

• Package type must be 8-MSOP (0.118", 3.00mm Width)
• Mounting type must be Surface Mount
• Pin count and footprint must be identical

Electrical Compatibility:

• Output type must be Rail-to-Rail
• Number of circuits must be 1
• Supply voltage range must encompass or be compatible with 2.3 V to 5.5 V
• Operating temperature range must support -40°C minimum
• Slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current must fall within acceptable operational ranges for the application

Compliance & Status:

• Product status must be Active
• RoHS3 compliance required
• MSL rating of 1 (Unlimited) preferred

The substitute parts identified (LTC6800HMS8#PBF and LTC6800HMS8#TRPBF) share identical mechanical packaging and rail-to-rail output architecture. Both are manufactured by Analog Devices Inc. and maintain active production status with full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: MCP616T-I/MS

The MCP616T-I/MS remains the specified component for applications designed around its general purpose amplifier architecture. Current inventory of 2,750 units supports immediate procurement. This part is actively manufactured and maintains full RoHS3 compliance with MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Substitute Option 1: LTC6800HMS8#PBF (Tube Packaging)

The LTC6800HMS8#PBF is functionally equivalent in mechanical form factor and electrical interface. This part is supplied in Tube packaging with 1,354 units in inventory. The LTC6800 series operates across the same maximum supply voltage (5.5 V) and shares identical 8-MSOP package geometry. This substitute exhibits superior electrical performance characteristics: lower input bias current (4 nA vs. 15 nA), reduced input offset voltage (100 µV vs. 150 µV), and significantly lower supply current (1.3 mA vs. 19 µA). Operating temperature range extends to 125°C, exceeding the MCP616T-I/MS specification of 85°C. RoHS3 compliance and MSL rating of 1 (Unlimited) are maintained.

Substitute Option 2: LTC6800HMS8#TRPBF (Cut Tape & Digi-Reel® Packaging)

The LTC6800HMS8#TRPBF provides identical electrical and mechanical specifications to the LTC6800HMS8#PBF, with the distinction of Cut Tape (CT) and Digi-Reel® packaging format. Inventory availability is 2,000 units. This packaging option accommodates automated pick-and-place assembly processes. All electrical performance advantages and compliance certifications remain consistent with the tube-packaged variant.

Substitution Constraints:

The LTC6800 series devices are classified as instrumentation amplifiers, whereas the MCP616T-I/MS is a general purpose amplifier. Both device types share identical package geometry, rail-to-rail output architecture, and single-circuit configuration. Minimum supply voltage differs: LTC6800 requires 2.7 V minimum versus MCP616T-I/MS at 2.3 V minimum. Applications operating below 2.7 V supply voltage cannot use LTC6800 substitutes. Slew rate of LTC6800 (0.2 V/µs) exceeds MCP616T-I/MS (0.08 V/µs), which may introduce different transient response characteristics in bandwidth-limited circuits.

Frequently Asked Questions (FAQ)

Q: Can the LTC6800HMS8#PBF be used as a direct replacement for the MCP616T-I/MS in all applications?

A: Direct replacement is possible only when the application supply voltage is 2.7 V or higher. The MCP616T-I/MS operates at 2.3 V minimum, while LTC6800 requires 2.7 V minimum. Additionally, the LTC6800 is an instrumentation amplifier architecture, whereas the MCP616T-I/MS is a general purpose amplifier. Circuit designs must be evaluated for compatibility with the instrumentation amplifier topology before substitution.

Q: What is the difference between LTC6800HMS8#PBF and LTC6800HMS8#TRPBF?

A: Both parts are electrically and mechanically identical. The difference is packaging format: LTC6800HMS8#PBF is supplied in Tube packaging, while LTC6800HMS8#TRPBF is supplied in Cut Tape (CT) and Digi-Reel® format. Tube packaging is suitable for manual handling and small-volume assembly. Cut Tape and Digi-Reel® packaging is optimized for automated pick-and-place assembly equipment.

Q: Are the substitute parts RoHS3 compliant?

A: Yes. Both LTC6800HMS8#PBF and LTC6800HMS8#TRPBF are ROHS3 Compliant with MSL rating of 1 (Unlimited), matching the compliance profile of the MCP616T-I/MS.

Q: What are the key electrical differences between the MCP616T-I/MS and LTC6800 substitutes?

A: The LTC6800 exhibits lower input bias current (4 nA vs. 15 nA), lower input offset voltage (100 µV vs. 150 µV), and significantly lower supply current (1.3 mA vs. 19 µA). Slew rate is higher (0.2 V/µs vs. 0.08 V/µs), and gain bandwidth product is slightly higher (200 kHz vs. 190 kHz). Operating temperature range extends to 125°C for LTC6800 versus 85°C for MCP616T-I/MS.

Q: Does the 8-MSOP package footprint remain identical across all three parts?

A: Yes. All three parts use the 8-MSOP package with 0.118" width and 3.00mm width specification. Pin count, pitch, and footprint are identical, allowing direct PCB layout compatibility.

Q: What is the minimum supply voltage requirement for each part?

A: MCP616T-I/MS requires 2.3 V minimum. Both LTC6800HMS8#PBF and LTC6800HMS8#TRPBF require 2.7 V minimum. Applications operating below 2.7 V cannot use LTC6800 substitutes.

Q: Are there any REACH or ECCN restrictions on these parts?

A: All three parts are REACH Unaffected and classified as EAR99 under ECCN regulations. HTSUS code is 8542.33.0001 for all parts.
