LT1014CN-NG Equivalent & Substitute Parts

Part Overview

The LT1014CN-NG is a general purpose operational amplifier featuring four independent circuits in a push-pull output configuration. This device is packaged in a 14-pin DIP format and is designed for through-hole mounting applications. The LT1014CN-NG is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and production continuity. Substitute parts must maintain functional compatibility across amplifier type, circuit count, output configuration, and electrical performance parameters.

Substitute Part Grouping Explanation

Substitution of the LT1014CN-NG is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Amplifier Type: General Purpose
• Number of Circuits: 4 independent circuits
• Output Type: Push-Pull configuration
• Slew Rate: 0.4 V/µs minimum
• Input Bias Current: 12 nA maximum
• Input Offset Voltage: 60 µV maximum
• Supply Current: 350 µA per four channels
• Maximum Supply Voltage: 44 V or greater

Physical Parameters:

• Mounting Type: Through Hole
• Package: 14-DIP (0.300", 7.62mm)
• Supplier Device Package: 14-PDIP

Compliance Parameters:

• RoHS3 Compliance required
• Operating Temperature Range: 0°C to 70°C

The LT1014CN (active product) meets all substitution criteria and serves as the direct equivalent to the obsolete LT1014CN-NG variant.

Parameter Comparison

Engineering Selection Recommendations

The LT1014CN is the direct substitute for the obsolete LT1014CN-NG. Both parts are manufactured by Texas Instruments and share identical functional specifications across all critical amplifier parameters including slew rate, input bias current, input offset voltage, and supply current.

Product Status Consideration: The LT1014CN maintains active product status with 6479 units in stock, ensuring supply continuity and long-term availability compared to the obsolete LT1014CN-NG variant.

Compliance Alignment: Both parts maintain ROHS3 compliance and identical operating temperature specifications (0°C to 70°C), supporting regulatory requirements and thermal design consistency.

Supply Voltage Specification: The LT1014CN is rated for a maximum supply voltage of 30 V, compared to 44 V for the LT1014CN-NG. Applications requiring supply voltages exceeding 30 V require design review to confirm compatibility with the substitute part's electrical ratings.

Packaging and Mounting: Both parts utilize identical 14-DIP through-hole packaging (0.300", 7.62mm), enabling direct board-level substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the LT1014CN directly replace the LT1014CN-NG in existing designs?

A: The LT1014CN is functionally equivalent to the LT1014CN-NG across all amplifier specifications including circuit count, output type, slew rate, and input characteristics. Both parts share identical 14-DIP packaging and through-hole mounting. However, applications operating at supply voltages above 30 V require design verification, as the LT1014CN is rated to 30 V maximum compared to 44 V for the LT1014CN-NG.

Q: What is the primary reason for substitution?

A: The LT1014CN-NG is classified as obsolete. The LT1014CN is the active equivalent part manufactured by Texas Instruments, ensuring ongoing supply availability and production support.

Q: Are there packaging differences between these parts?

A: Both the LT1014CN-NG and LT1014CN are supplied in 14-PDIP packaging with 14-DIP (0.300", 7.62mm) case dimensions. The primary packaging difference is that the LT1014CN is supplied in tube packaging, while the LT1014CN-NG was supplied as a prototype variant. This difference does not affect electrical performance or board-level compatibility.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the LT1014CN-NG and LT1014CN are ROHS3 compliant, supporting regulatory requirements for restricted substance management.

Q: What are the critical electrical parameters that must match for substitution?

A: Substitution is based on matching the following parameters: four independent general purpose amplifier circuits, push-pull output configuration, 0.4 V/µs slew rate, 12 nA input bias current, 60 µV input offset voltage, 350 µA supply current per four channels, and 0°C to 70°C operating temperature range.

Q: Is the LT1014CN available in the same quantities as the LT1014CN-NG?

A: The LT1014CN has significantly higher inventory availability with 6479 units in stock compared to 972 units for the LT1014CN-NG, providing improved supply security for production requirements.
