LT1014CNG4 Equivalent & Substitute Parts

Part Overview

The LT1014CNG4 is a general-purpose operational amplifier integrated circuit manufactured by Texas Instruments, configured as a 4-circuit device in a 14-pin DIP package. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement.

The LT1014CNG4 serves applications requiring low-power, general-purpose amplification with moderate bandwidth characteristics. Due to its obsolete status, alternative part numbers from active product lines provide functional continuity while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the LT1014CNG4 is determined by strict electrical and mechanical compatibility across the following critical parameters:

Primary Substitution Criteria:

Number of circuits: 4 (mandatory)
Package type: 14-DIP (0.300", 7.62mm) (mandatory)
Mounting type: Through Hole (mandatory)
Slew rate: 0.4 V/µs (mandatory)
Gain bandwidth product: 1 MHz (mandatory)
Voltage supply span minimum: 4 V (mandatory)
Voltage supply span maximum: 30 V or greater (mandatory)
Operating temperature range: 0°C to 70°C or extended (mandatory)

Substitute Parts Classified by Compatibility:

Group 1: Direct Electrical and Mechanical Equivalents (Active Status) Parts meeting all primary substitution criteria with identical or superior electrical specifications and active product status:

LT1014CN (Texas Instruments)
LT1014ACN#PBF (Analog Devices Inc.)
LT1014CN#PBF (Analog Devices Inc.)
LT1014DN#PBF (Analog Devices Inc.)
LT1014IN#PBF (Analog Devices Inc.)

Group 2: Functional Alternatives with Different Performance Characteristics Parts sharing the same package and mounting type but with significantly different electrical parameters:

LT1179ACN#PBF (Analog Devices Inc.)
LT1179CN#PBF (Analog Devices Inc.)
LT1179IN#PBF (Analog Devices Inc.)

The LT1179 series operates at substantially lower slew rates (0.04 V/µs versus 0.4 V/µs) and lower gain bandwidth product (85 kHz versus 1 MHz), making these parts suitable only for applications where reduced bandwidth and slower signal processing are acceptable.

Engineering Selection Recommendations

Primary Recommendation for Direct Replacement:

LT1014CN (Texas Instruments) or LT1014ACN#PBF (Analog Devices Inc.) are the preferred substitutes for the obsolete LT1014CNG4. Both parts maintain identical electrical specifications across all critical parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, and supply current. Both are active products with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

LT1014ACN#PBF offers extended maximum supply voltage (44 V versus 30 V), providing additional design margin in applications with higher supply rails.

Secondary Recommendations for Extended Temperature Range:

LT1014IN#PBF (Analog Devices Inc.) extends the operating temperature range to -40°C to 85°C while maintaining all other electrical specifications identical to the original part. This variant is suitable for applications requiring industrial or military temperature performance.

Alternative Selection for Low-Power Applications:

The LT1179 series (LT1179ACN#PBF, LT1179CN#PBF, LT1179IN#PBF) provides substantially reduced supply current (16-17 µA versus 350 µA) at the cost of reduced bandwidth performance. These parts are suitable only for applications where bandwidth requirements are below 85 kHz and power consumption is a primary design constraint.

All recommended substitutes are ROHS3 compliant, REACH unaffected, and available in active product status with confirmed inventory.

Frequently Asked Questions (FAQ)

Q1: Can LT1014CN be used as a direct replacement for LT1014CNG4?

A: Yes. LT1014CN maintains identical electrical specifications across all critical parameters: 0.4 V/µs slew rate, 1 MHz gain bandwidth product, 12 nA input bias current, 60 µV input offset voltage, and 350 µA supply current. Both use the same 14-DIP package. LT1014CN is an active product, whereas LT1014CNG4 is obsolete.

Q2: What is the difference between LT1014ACN#PBF and LT1014CN#PBF?

A: Both parts share identical slew rate (0.4 V/µs), gain bandwidth product (1 MHz), and input offset voltage (60 µV). The primary difference is input bias current: LT1014ACN#PBF specifies 12 nA, while LT1014CN#PBF specifies 15 nA. LT1014ACN#PBF also supports extended maximum supply voltage (44 V versus 30 V). Both are suitable substitutes for the original part.

Q3: When should LT1014IN#PBF be selected instead of LT1014CN#PBF?

A: LT1014IN#PBF extends the operating temperature range to -40°C to 85°C, compared to 0°C to 70°C for LT1014CN#PBF. Select LT1014IN#PBF when the application requires operation outside the standard commercial temperature range, such as in industrial, automotive, or military environments.

Q4: Are LT1179 series parts suitable replacements for LT1014CNG4?

A: LT1179 series parts share the same 14-DIP package and mounting type but have fundamentally different electrical characteristics. Slew rate is reduced to 0.04 V/µs (10 times slower), and gain bandwidth product is reduced to 85 kHz (approximately 12 times lower). Supply current is dramatically reduced to 16-17 µA. These parts are suitable only for applications where reduced bandwidth and lower power consumption are acceptable trade-offs.

Q5: What packaging options are available for LT1014 substitutes?

A: All recommended substitutes are supplied in Tube packaging. The 14-DIP (0.300", 7.62mm) package format is consistent across all variants, ensuring mechanical compatibility with existing PCB designs and socket configurations.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts—LT1014CN, LT1014ACN#PBF, LT1014CN#PBF, LT1014DN#PBF, LT1014IN#PBF, and LT1179 series variants—are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q7: Which substitute offers the widest supply voltage range?

A: LT1014ACN#PBF and LT1014CN#PBF support maximum supply voltage of 44 V, compared to 30 V for the original LT1014CNG4 and other variants. This extended range provides additional design flexibility for applications with higher supply rails.

Q8: What is the inventory status of substitute parts?

A: LT1014CN maintains the highest inventory (6,479 pcs), followed by LT1014IN#PBF (3,490 pcs) and LT1179CN#PBF (2,364 pcs). All recommended substitutes are confirmed in stock as new original components.
