TS27M4CD Equivalent & Substitute Parts
Part Overview
The TS27M4CD is a CMOS amplifier integrated circuit manufactured by STMicroelectronics, configured as a 4-circuit operational amplifier in a 14-SOIC surface mount package. This device is classified as obsolete, indicating it is no longer in active production. The TS27M4CD operates across a supply voltage range of 3V to 16V with a gain bandwidth product of 1 MHz and a slew rate of 0.6V/µs. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and system maintenance applications requiring compatible 4-circuit amplifier solutions in the same package footprint.

Substitute Part Grouping Explanation
Substitution of the TS27M4CD is determined by the following critical parameters:
Package Compatibility: All substitute parts must use the 14-SOIC (0.154", 3.90mm Width) surface mount package to ensure direct PCB footprint compatibility.
Circuit Configuration: All substitutes must provide 4 independent amplifier circuits within a single package.
Supply Voltage Range: The TS27M4CD operates from 3V to 16V. Substitute parts with wider supply ranges (such as 3V to 26V, 30V, or 32V) are electrically compatible and provide enhanced flexibility for multi-voltage system designs.
Amplifier Type: The TS27M4CD is a CMOS amplifier. Substitutes include both CMOS and general-purpose amplifier types. General-purpose amplifiers (such as the LM2902 series) provide functional equivalence in 4-circuit configurations with comparable gain bandwidth products and slew rates.
Electrical Performance: Key performance metrics include gain bandwidth product (1 MHz nominal), slew rate (0.6V/µs), input bias current (1 pA), and output current per channel (45 mA). Substitute parts with comparable or superior performance in these parameters are functionally equivalent.
Product Status and Availability: The TS27M4CD is obsolete. Active and last-time-buy substitute parts ensure design continuity and production support.

Engineering Selection Recommendations
Primary Substitutes for Active Production:
LM2902QDRQ1 and LM2902M/NOPB are recommended as primary substitutes. Both are manufactured by Texas Instruments with active product status. LM2902QDRQ1 provides automotive-grade qualification (AEC-Q100) with extended operating temperature range (-40°C to 125°C) and higher output current per channel (60 mA versus 45 mA in the TS27M4CD). LM2902M/NOPB operates within the LinCMOS™ series with active status and comparable electrical performance. Both parts maintain the 14-SOIC package footprint and 4-circuit configuration.
Secondary Substitutes for Extended Supply Voltage Applications:
LM2902KAVQDR and LM2902KVQDRG4 support supply voltages up to 30V, providing enhanced flexibility for multi-voltage system designs. Both are manufactured by Texas Instruments with automotive-grade qualification. These parts are suitable for applications requiring wider supply voltage margins beyond the TS27M4CD's 16V maximum.
CMOS Amplifier Alternative:
LMC6034IM/NOPB is a CMOS amplifier matching the TS27M4CD's amplifier type classification. This part provides superior slew rate (1.1V/µs) and gain bandwidth product (1.4 MHz) with lower input bias current (0.04 pA). However, LMC6034IM/NOPB is classified as obsolete and has a higher minimum supply voltage (4.75V). This part is suitable only for applications where CMOS characteristics are mandatory and supply voltage constraints are not limiting.
Compliance and Regulatory Considerations:
All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the TS27M4CD's regulatory status. Moisture sensitivity level (MSL) is 1 (Unlimited) across all parts, indicating no special moisture handling requirements during storage or assembly.
Frequently Asked Questions (FAQ)
Q: Can LM2902 series parts directly replace the TS27M4CD without PCB modifications?
A: Yes. All LM2902 series substitutes use the 14-SOIC (0.154", 3.90mm Width) package, which provides identical PCB footprint compatibility with the TS27M4CD. No PCB layout changes are required for mechanical or electrical connection.
Q: What is the primary difference between CMOS and general-purpose amplifier types in this comparison?
A: The TS27M4CD is a CMOS amplifier with extremely low input bias current (1 pA). General-purpose amplifiers such as the LM2902 series have higher input bias currents (20 to 45 nA) but provide comparable gain bandwidth products and slew rates. For applications sensitive to input bias current, the LMC6034IM/NOPB CMOS alternative is available, though it is obsolete.
Q: Are there supply voltage limitations when substituting the TS27M4CD?
A: The TS27M4CD operates from 3V to 16V. Most LM2902 series substitutes support 3V to 26V or 3V to 32V, providing wider operating margins. LMC6034IM/NOPB has a higher minimum supply voltage (4.75V) and lower maximum (15.5V), making it suitable only for applications within this narrower range.
Q: Which substitute part is recommended for automotive applications?
A: LM2902QDRQ1 and LM2902QDRG4Q1 are qualified to AEC-Q100 automotive standards with extended operating temperature range (-40°C to 125°C). These parts are suitable for automotive and industrial applications requiring temperature stability and reliability certifications.
Q: What is the significance of "Last Time Buy" product status?
A: Parts designated as "Last Time Buy" (such as LM2902KD, LM2902KVQDRG4, and LM2902QDRG4Q1) are in the final phase of production before discontinuation. These parts remain available for a limited time but should not be selected for new long-term production designs. Active status parts (LM2902KAVQDR, LM2902M/NOPB, LM2902MX/NOPB, LM2902QDRQ1) are preferred for ongoing production support.
Q: How do output current specifications affect circuit design?
A: The TS27M4CD provides 45 mA per channel. LM2902 series parts provide 30 to 60 mA per channel depending on the specific variant. LM2902QDRG4Q1 and LM2902QDRQ1 provide 60 mA per channel, offering higher output drive capability. Applications requiring maximum output current should select these higher-rated variants.
Q: Is thermal management different between the TS27M4CD and substitute parts?
A: All parts use identical 14-SOIC surface mount packages with equivalent thermal characteristics. No changes to PCB thermal design, heatsinking, or thermal management are required when substituting between these parts.
Q: Can the TS27M4CD be used in new designs, or should substitutes be selected?
A: The TS27M4CD is classified as obsolete and is no longer manufactured. New designs should select from active or last-time-buy substitute parts to ensure long-term supply chain continuity and production support. LM2902QDRQ1 and LM2902M/NOPB are recommended for new designs due to their active product status.
