TS1872AIN Equivalent & Substitute Parts

Part Overview

The TS1872AIN is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring dual circuits in an 8-Mini DIP through-hole package. This device provides rail-to-rail output capability with a supply voltage range of 1.8 V to 6 V and operates across an extended temperature range of -40°C to 125°C.

The TS1872AIN is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term system maintenance where this device is currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS1872AIN is determined by the following critical parameters:

Functional Requirements:

• Dual-channel general-purpose operational amplifier configuration
• Rail-to-rail output capability
• 8-pin DIP package footprint compatibility (0.300", 7.62mm)
• Through-hole mounting technology

Electrical Operating Range:

• Supply voltage compatibility: 1.8 V to 6 V minimum and maximum spans
• Operating temperature range: -40°C to 125°C
• Input offset voltage: 3 mV maximum

Compliance & Regulatory:

• ROHS3 compliance requirement
• REACH unaffected status
• EAR99 export classification

The MCP6272-E/P from Microchip Technology satisfies all substitution criteria within these defined parameters.

Engineering Selection Recommendations

Primary Substitute: MCP6272-E/P

The MCP6272-E/P is the qualified substitute for the TS1872AIN based on the following engineering criteria:

Functional Equivalence: The MCP6272-E/P maintains identical pin configuration, package footprint, and dual-channel general-purpose amplifier architecture. Both devices feature rail-to-rail output and are housed in 8-DIP through-hole packages with identical mechanical dimensions.

Regulatory & Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current manufacturing and environmental regulations. Both carry EAR99 export classification.

Product Availability: The TS1872AIN is obsolete with limited remaining inventory. The MCP6272-E/P is actively manufactured by Microchip Technology, providing assured long-term availability and supply chain continuity.

Operating Range Compatibility: The MCP6272-E/P operates across the -40°C to 125°C temperature range, matching the TS1872AIN specification. The maximum supply voltage of 6 V is identical. The minimum supply voltage requirement of 2 V for the MCP6272-E/P is higher than the TS1872AIN specification of 1.8 V; applications requiring operation below 2 V supply voltage cannot use this substitute.

Performance Characteristics: The MCP6272-E/P demonstrates improved electrical performance in several parameters: slew rate of 0.9 V/µs exceeds the TS1872AIN specification of 0.6 V/µs, gain bandwidth product of 2 MHz exceeds 1.8 MHz, and input bias current of 1 pA is significantly lower than 70 nA. Supply current consumption is reduced to 170 µA per channel compared to 500 µA, providing power efficiency benefits. Output current per channel is 25 mA, lower than the TS1872AIN specification of 80 mA; applications requiring higher output current must evaluate this limitation.

Frequently Asked Questions (FAQ)

Q: Can the MCP6272-E/P directly replace the TS1872AIN in existing circuit boards?

A: The MCP6272-E/P is mechanically and functionally compatible with the TS1872AIN due to identical 8-DIP package dimensions and pin configuration. However, circuit performance may change due to differences in output current capability (25 mA versus 80 mA) and minimum supply voltage requirement (2 V versus 1.8 V). Verify that your application does not depend on the higher output current specification or operation below 2 V supply voltage.

Q: What is the primary reason for substituting the TS1872AIN?

A: The TS1872AIN is classified as obsolete. The MCP6272-E/P is an active product with assured manufacturing continuity and availability, making it the appropriate choice for new designs and long-term production support.

Q: Are there any electrical performance differences that would affect circuit operation?

A: The MCP6272-E/P exhibits superior performance in slew rate (0.9 V/µs versus 0.6 V/µs), gain bandwidth product (2 MHz versus 1.8 MHz), and input bias current (1 pA versus 70 nA). These improvements generally enhance circuit performance. However, the MCP6272-E/P provides lower output current per channel (25 mA versus 80 mA) and requires a minimum supply voltage of 2 V instead of 1.8 V. Evaluate whether your circuit design depends on these specifications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TS1872AIN and MCP6272-E/P are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Regulatory compliance is maintained with this substitution.

Q: What is the difference between the 8-Mini DIP and 8-PDIP package designations?

A: Both designations refer to 8-pin dual inline packages with identical physical dimensions of 0.300" (7.62mm) width. The terminology difference reflects manufacturer naming conventions; the packages are mechanically and electrically interchangeable for through-hole mounting applications.

Q: Is the MCP6272-E/P available in the same packaging format?

A: Yes. The MCP6272-E/P is supplied in 8-PDIP (plastic dual inline package) format with identical 0.300" (7.62mm) spacing and through-hole mounting compatibility. The package footprint is directly compatible with existing PCB designs.

Q: What supply voltage range should be used with the MCP6272-E/P?

A: The MCP6272-E/P operates with a minimum supply voltage of 2 V and maximum of 6 V. If your application requires operation below 2 V, the MCP6272-E/P is not suitable. The TS1872AIN supported operation down to 1.8 V; verify your circuit's minimum supply voltage requirement before substitution.
