TLV2470IP Equivalent & Substitute Parts

Part Overview

The TLV2470IP is a general purpose operational amplifier manufactured by Texas Instruments, housed in an 8-PDIP through-hole package. This device features rail-to-rail output capability and is designed for low-power applications requiring single-circuit amplification. The TLV2470IP is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Substitute parts must maintain functional compatibility across critical electrical parameters including supply voltage range, output type, and package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV2470IP are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Voltage Supply Span: 2.7 V to 6 V minimum overlap

Substitution Categories:

Direct Equivalent (TLV2471IP): Identical electrical specifications and package configuration. Active product status. Differs only in packaging format (Tube vs. unspecified for main part) and product lifecycle status.

Manufacturer-Recommended Substitute (MCP603-I/P): Microchip Technology alternative meeting core functional requirements. Maintains rail-to-rail output, single-circuit configuration, 8-DIP package, and overlapping supply voltage range. Operational temperature range differs (−40°C to 85°C vs. −40°C to 125°C). Active product status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer Preferred):

The TLV2471IP is the primary substitute for the obsolete TLV2470IP. Both devices are manufactured by Texas Instruments and share identical electrical specifications. The TLV2471IP maintains active product status, ensuring long-term availability and supply chain continuity. Selection of TLV2471IP eliminates design re-qualification requirements and preserves performance characteristics across all specified parameters.

For Cross-Manufacturer Substitution:

The MCP603-I/P from Microchip Technology is a manufacturer-recommended alternative when TLV2471IP availability is constrained. This device maintains functional compatibility through matching package configuration (8-DIP), supply voltage range (2.7 V to 6 V), and rail-to-rail output capability. The MCP603-I/P exhibits superior power efficiency (230 µA supply current vs. 600 µA) and lower input bias current (1 pA vs. 2.5 pA).

Critical Consideration for MCP603-I/P Selection:

The MCP603-I/P operating temperature range is limited to −40°C to 85°C, compared to the TLV2470IP specification of −40°C to 125°C. Applications requiring operation above 85°C must retain the TLV2471IP or conduct thermal analysis to confirm MCP603-I/P suitability. The MCP603-I/P exhibits higher input offset voltage (700 µV vs. 250 µV) and reduced output current capability (22 mA vs. 35 mA per channel), which may impact precision and load-driving applications.

Compliance and Regulatory Status:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. No additional compliance modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can TLV2471IP be used as a direct replacement for TLV2470IP?

A: Yes. The TLV2471IP is a direct functional equivalent with identical electrical specifications. Both devices are single-circuit, general purpose operational amplifiers in 8-DIP packages with rail-to-rail output and 2.7 V to 6 V supply range. The primary difference is product lifecycle status: TLV2470IP is obsolete while TLV2471IP is active.

Q: What are the key differences between TLV2471IP and MCP603-I/P?

A: Both devices share the same package (8-DIP), supply voltage range (2.7 V to 6 V), and rail-to-rail output configuration. Differences include: (1) Operating temperature range—TLV2471IP supports −40°C to 125°C while MCP603-I/P is limited to −40°C to 85°C; (2) Supply current—MCP603-I/P consumes 230 µA versus 600 µA for TLV2471IP; (3) Input offset voltage—MCP603-I/P is 700 µV versus 250 µV for TLV2471IP; (4) Output current—MCP603-I/P provides 22 mA versus 35 mA for TLV2471IP.

Q: Is the 8-DIP package identical across all three parts?

A: Yes. All three devices use the 8-DIP (0.300", 7.62mm) package with through-hole mounting. Pin-to-pin compatibility is maintained, allowing direct socket substitution without PCB modifications.

Q: Which substitute should be selected for high-temperature applications?

A: The TLV2471IP must be selected for applications requiring operation above 85°C, as it supports the full −40°C to 125°C temperature range. The MCP603-I/P is limited to 85°C maximum and is unsuitable for high-temperature environments without thermal derating analysis.

Q: Does MCP603-I/P offer any performance advantages?

A: The MCP603-I/P provides lower supply current consumption (230 µA vs. 600 µA) and lower input bias current (1 pA vs. 2.5 pA), making it advantageous for battery-powered and ultra-low-bias applications. However, it exhibits higher input offset voltage (700 µV vs. 250 µV) and reduced output current capability (22 mA vs. 35 mA), which may limit precision and high-load applications.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. TLV2470IP, TLV2471IP, and MCP603-I/P are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What inventory status should influence part selection?

A: TLV2471IP has 1,175 pieces in stock while MCP603-I/P has 15,755 pieces available. For applications with extended production timelines, MCP603-I/P may offer superior supply chain security despite its operational temperature limitation.
