TS507CD Equivalent & Substitute Parts
Part Overview
The TS507CD is a general-purpose operational amplifier manufactured by STMicroelectronics in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for single-circuit amplification applications. The TS507CD is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support, production continuity, and system maintenance. Substitute parts must maintain compatibility with the 8-SOIC package format and support the electrical operating parameters of the original design.

Engineering Selection Recommendations
For Direct Replacement with Enhanced Performance:
LMP2011MA/NOPB and LMV2011MAX/NOPB are active, production-supported alternatives that maintain the 8-SOIC package and rail-to-rail output configuration. Both parts are RoHS3 compliant with MSL 1 rating. LMP2011MA/NOPB supports the full TS507CD supply voltage range (2.7 V to 5.25 V) and extended operating temperature (-40°C to 125°C). LMV2011MAX/NOPB operates within 0°C to 70°C, matching the TS507CD lower temperature bound. Both deliver superior slew rate (4 V/µs versus 0.6 V/µs) and gain bandwidth product (3 MHz versus 1.9 MHz).
For Power-Constrained Applications:
MCP6041-I/SN and MCP6041T-I/SN are active Microchip alternatives with dramatically reduced supply current (600 nA versus 850 µA). These parts maintain 8-SOIC packaging and rail-to-rail output. Operating temperature range is -40°C to 85°C, covering the TS507CD specification. Supply voltage range extends to 1.4 V minimum and 6 V maximum, providing broader compatibility. Trade-offs include significantly lower slew rate (0.003 V/µs) and gain bandwidth product (14 kHz), suitable only for DC or very low-frequency applications.
For Moderate Performance with Low Power:
MCP6051-E/SN and MCP6061-E/SN offer intermediate performance with reduced supply current (30 µA and 60 µA respectively). Both support -40°C to 125°C operating range and extended supply voltage (1.8 V to 6 V). MCP6061-E/SN provides higher slew rate (0.25 V/µs) and gain bandwidth product (730 kHz) compared to MCP6051-E/SN (0.15 V/µs and 385 kHz).
Compliance and Availability:
All substitute parts listed are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the TS507CD specification. All substitute parts are currently in active production status with documented inventory availability.
Frequently Asked Questions (FAQ)
Q: Can LMP2011MA/NOPB directly replace TS507CD in existing designs?
A: LMP2011MA/NOPB is mechanically and electrically compatible with TS507CD. Both use 8-SOIC packaging and provide rail-to-rail output. The supply voltage range of LMP2011MA/NOPB (2.7 V to 5.25 V) encompasses the TS507CD operating range (2.7 V to 5.5 V). Performance parameters are superior, including higher slew rate and gain bandwidth product. No circuit modifications are required for substitution.
Q: What is the primary difference between MCP6041 and MCP6051 variants?
A: MCP6041 and MCP6051 differ in slew rate and gain bandwidth product. MCP6041 operates at 0.003 V/µs slew rate with 14 kHz gain bandwidth product, optimized for ultra-low power consumption (600 nA). MCP6051 provides 0.15 V/µs slew rate with 385 kHz gain bandwidth product at 30 µA supply current. Selection depends on application frequency requirements and power budget constraints.
Q: Are packaging variants (Tube, Tape & Reel, Cut Tape) electrically equivalent?
A: Packaging variants of the same part number (e.g., MCP6041-E/SN in Tube versus MCP6041T-E/SN in Tape & Reel) are electrically identical. Packaging differences affect only handling, storage, and assembly processes. Selection is based on manufacturing workflow and inventory management requirements, not electrical performance.
Q: What is the operating temperature impact when substituting TS507CD with LMV2011MA/NOPB?
A: LMV2011MA/NOPB operates within 0°C to 70°C, which covers the TS507CD lower bound (0°C) but does not extend to the TS507CD upper bound (85°C). For applications requiring operation above 70°C, LMV2011MA/NOPB is not suitable. LMP2011MA/NOPB or MCP6041-I/SN support extended temperature ranges (-40°C to 125°C and -40°C to 85°C respectively).
Q: Can MCP6041 series replace TS507CD in high-frequency applications?
A: MCP6041 series is not suitable for high-frequency applications. With a gain bandwidth product of only 14 kHz, MCP6041 is limited to DC and very low-frequency signal conditioning. TS507CD operates at 1.9 MHz gain bandwidth product. For frequency-dependent applications, LMP2011MA/NOPB (3 MHz) or MCP6061-E/SN (730 kHz) are appropriate alternatives.
Q: What is the significance of input bias current differences between TS507CD and substitutes?
A: TS507CD has 8 nanoampere input bias current. LMP2011MA/NOPB and LMV2011MAX/NOPB reduce this to 3 picoamperes, approximately 2,700 times lower. MCP6041, MCP6051, and MCP6061 series specify 1 picoampere. Lower input bias current reduces errors in high-impedance signal paths and minimizes offset drift with temperature. Selection depends on input impedance and accuracy requirements of the application circuit.
Q: Are all substitute parts RoHS3 compliant?
A: All substitute parts listed in this reference are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching TS507CD specifications. Compliance documentation is available from respective manufacturers.
