Engineering Selection Recommendations

For Direct Replacement with Enhanced Performance:

LMP2011MA/NOPB and LMV2011MAX/NOPB are the primary substitutes for the TS507CDT. Both devices are active products with ROHS3 compliance and MSL 1 rating. These parts maintain the 8-SOIC package footprint and rail-to-rail output configuration. The LMP2011MA/NOPB operates across an extended temperature range (-40°C to 125°C) compared to the TS507CDT (0°C to 85°C), providing broader application flexibility. The LMV2011MAX/NOPB is available in Tape & Reel packaging, suitable for high-volume production environments.

For Power-Constrained Applications:

The MCP6041 series (MCP6041-E/SN, MCP6041-I/SN, MCP6041T-E/SN, MCP6041T-I/SN) offers ultra-low supply current consumption (0.6 µA) compared to the TS507CDT (850 µA). These devices are active products with ROHS3 compliance and MSL 1 rating. The MCP6041T-E/SN variant supports the full industrial temperature range (-40°C to 125°C) and is available in Tape & Reel packaging. Trade-offs include significantly reduced slew rate (0.003 V/µs versus 0.6 V/µs) and gain bandwidth product (14 kHz versus 1.9 MHz), limiting applicability to low-frequency signal processing.

For Intermediate Performance Requirements:

The MCP6051 series (MCP6051-E/SN, MCP6051T-E/SN) and MCP6061-E/SN provide intermediate performance characteristics. These devices maintain active product status, ROHS3 compliance, and MSL 1 rating. The MCP6051T-E/SN operates across -40°C to 125°C and is available in Tape & Reel packaging. Supply current consumption ranges from 30 µA to 60 µA, representing a significant reduction from the TS507CDT while maintaining higher slew rate and gain bandwidth product than the MCP6041 series.

Compliance and Regulatory Considerations:

All substitute parts listed are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All devices maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes. Packaging options include Tube, Bulk, Tape & Reel, and Cut Tape variants to accommodate different procurement and manufacturing workflows.

Frequently Asked Questions (FAQ)

Q: Can the LMP2011MA/NOPB directly replace the TS507CDT without circuit modifications?

A: The LMP2011MA/NOPB is mechanically and electrically compatible with the TS507CDT. Both devices use the 8-SOIC package, feature rail-to-rail output, and operate within overlapping supply voltage ranges (2.7 V to 5.25 V). Pin configuration and functional behavior are equivalent. No circuit modifications are required for direct substitution. However, the LMP2011MA/NOPB exhibits superior performance characteristics (higher slew rate, lower input offset voltage), which may alter circuit behavior in applications with tight timing or precision requirements.

Q: What is the primary difference between MCP6041 and MCP6051 variants?

A: The MCP6041 series is optimized for ultra-low power consumption (0.6 µA supply current) with minimal bandwidth (14 kHz gain bandwidth product). The MCP6051 series provides intermediate performance with 30 µA supply current and 385 kHz gain bandwidth product. Selection depends on application requirements: MCP6041 for battery-powered or energy-harvesting systems; MCP6051 for applications requiring higher signal bandwidth with moderate power consumption.

Q: Are Tape & Reel and Tube packaging variants functionally identical?

A: Tape & Reel and Tube packaging variants contain identical die and electrical specifications. Packaging differences affect only procurement, storage, and assembly processes. Tape & Reel packaging is optimized for automated pick-and-place assembly in high-volume production. Tube packaging is suitable for lower-volume applications and manual assembly. Electrical performance and reliability are equivalent across packaging variants.

Q: Does the extended temperature range of LMP2011MA/NOPB (-40°C to 125°C) affect circuit design?

A: The extended temperature range does not require circuit design modifications. The LMP2011MA/NOPB maintains specified electrical parameters across its full operating range. Applications limited to 0°C to 85°C operation experience no performance degradation. The extended range provides design margin for future applications or environmental stress conditions without circuit redesign.

Q: Which substitute part is recommended for battery-powered applications?

A: The MCP6041 series is recommended for battery-powered applications due to ultra-low supply current consumption (0.6 µA). This represents a 1,417-fold reduction compared to the TS507CDT (850 µA). The MCP6041T-E/SN variant is preferred for production applications, offering active product status, ROHS3 compliance, extended temperature range (-40°C to 125°C), and Tape & Reel packaging. Trade-offs include reduced bandwidth (14 kHz) and slew rate (0.003 V/µs), limiting applicability to low-frequency signal conditioning.

Q: Is the TS507CDT still available for procurement?

A: The TS507CDT is classified as obsolete, indicating discontinued production by STMicroelectronics. Availability is limited to existing inventory from authorized distributors. Current inventory levels are reported at 1,601 pieces. For new designs or long-term production support, substitution with active products (LMP2011MA/NOPB, MCP6041 series, or MCP6051 series) is recommended to ensure supply chain continuity.

Q: What is the impact of reduced output current in substitute parts?

A: The TS507CDT provides 128 mA output current per channel. Substitute parts provide reduced output current: LMP2011MA/NOPB (17 mA), MCP6041 series (20 mA), and MCP6051 series (20 mA). Applications requiring high output current (>20 mA) may require external buffering or output stage modifications. Low-impedance load applications (< 250 Ω) may experience reduced output swing or require alternative topologies.

Q: Are all substitute parts suitable for audio frequency applications?

A: The LMP2011MA/NOPB, LMV2011MA/NOPB, LMV2011MAX/NOPB, MCP6051-E/SN, MCP6051T-E/SN, and MCP6061-E/SN are suitable for audio frequency applications (20 Hz to 20 kHz). The MCP6041 series, with 14 kHz gain bandwidth product, is marginal for full-range audio applications but suitable for speech frequency processing (300 Hz to 3.4 kHz). Selection depends on specific bandwidth requirements and acceptable frequency response limitations.
