LT1014MJ Equivalent & Substitute Parts

Part Overview

The LT1014MJ is a general-purpose operational amplifier integrated circuit manufactured by Analog Devices Inc., configured as a quad amplifier with four independent circuits in a 14-pin ceramic dual-in-line package (14-CERDIP). This device is classified as obsolete, indicating that it is no longer in active production. The LT1014MJ operates across a wide supply voltage range of 4V to 44V and maintains performance across an extended temperature range of -55°C to 125°C, making it suitable for industrial and military applications.

Due to its obsolete status, locating equivalent or substitute components becomes necessary for system maintenance, repair, and redesign efforts. Substitute parts must maintain functional compatibility through matching electrical characteristics, package compatibility, and operational parameters while considering current product availability and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the LT1014MJ is determined by the following critical parameters: quad amplifier configuration (4 circuits), general-purpose amplifier type, through-hole mounting, 14-pin DIP package format, slew rate of 0.4V/µs, supply voltage range spanning 4V minimum to 44V maximum, and operating temperature range of -55°C to 125°C.

The substitute parts identified maintain these core electrical and mechanical characteristics. However, variations exist in specific parameters that must be evaluated for application compatibility:

Critical Matching Parameters:

• Number of circuits: 4 (all substitutes match)
• Amplifier type: General Purpose (all substitutes match)
• Slew rate: 0.4V/µs (all substitutes match)
• Mounting type: Through Hole (all substitutes match)
• Package format: 14-pin DIP variants (all substitutes match)
• Supply voltage minimum: 4V (all substitutes match)

Parameters with Acceptable Variations:

• Gain Bandwidth Product: 700 kHz to 1 MHz
• Current - Input Bias: 12 nA to 15 nA
• Current - Output / Channel: 20 mA to 25 mA
• Voltage - Supply Span (Max): 30V to 44V
• Operating Temperature (Max): 105°C to 125°C
• Output Type: Standard or Push-Pull configuration

Engineering Selection Recommendations

LT1014AMJB (Texas Instruments)

The LT1014AMJB is an active product offering full compatibility with the LT1014MJ across all critical electrical parameters. This device maintains the 4-circuit quad amplifier configuration, identical slew rate, matching supply voltage range (4V to 44V), and extended temperature range (-55°C to 125°C). The LT1014AMJB features Push-Pull output configuration and slightly improved input bias current (12 nA versus 15 nA). The device is ROHS3 compliant and carries active product status, ensuring long-term availability and supply chain stability. Current inventory of 1,134 units is available. This substitute is recommended for applications requiring extended supply voltage operation and full temperature range performance.

LT1014DIN (Texas Instruments)

The LT1014DIN maintains functional compatibility with the LT1014MJ in quad amplifier configuration, slew rate, and gain bandwidth product (1 MHz). However, this device operates with a reduced maximum supply voltage of 30V compared to the 44V maximum of the LT1014MJ, and a narrower operating temperature range of -40°C to 105°C. The LT1014DIN is classified as Last Time Buy, indicating limited future availability. This substitute is suitable only for applications operating within the 4V to 30V supply range and -40°C to 105°C temperature range. Current inventory of 19,970 units is available. ROHS3 compliance is confirmed.

LT1014MJB (Texas Instruments)

The LT1014MJB provides direct functional equivalence to the LT1014MJ with identical package format (14-CDIP), supply voltage range (4V to 44V), and operating temperature range (-55°C to 125°C). This device is an active product with ROHS3 compliance. The LT1014MJB features Push-Pull output configuration and improved input bias current (12 nA). Current inventory of 1,104 units is available. This substitute is recommended as the primary replacement for the obsolete LT1014MJ, offering full electrical compatibility and assured long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the LT1014AMJB directly replace the LT1014MJ in all applications?

A: The LT1014AMJB is electrically compatible with the LT1014MJ across all critical parameters including supply voltage range (4V to 44V), operating temperature range (-55°C to 125°C), and quad amplifier configuration. The primary difference is the Push-Pull output type in the LT1014AMJB versus unspecified output type in the LT1014MJ. Direct substitution is valid for applications where output drive capability is not a limiting factor.

Q: What is the significance of the LT1014DIN being classified as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has announced the end of production for this device. While current inventory of 19,970 units is available, future procurement will not be possible once existing stock is depleted. Applications requiring long-term component availability should transition to active products such as the LT1014AMJB or LT1014MJB.

Q: Why does the LT1014DIN have a lower maximum supply voltage (30V) compared to the LT1014MJ (44V)?

A: The LT1014DIN is a different variant within the LT1014 product family with different electrical specifications. Applications requiring operation above 30V supply voltage must use the LT1014AMJB or LT1014MJB, both of which support the full 44V maximum supply voltage.

Q: Are all substitute parts available in the same 14-pin DIP package?

A: All substitute parts use 14-pin DIP package formats compatible with through-hole mounting. The LT1014MJ and LT1014AMJB and LT1014MJB use 14-CDIP (ceramic DIP), while the LT1014DIN uses 14-PDIP (plastic DIP). Both package types are mechanically and electrically compatible for through-hole PCB mounting.

Q: What is the difference between the LT1014AMJB and LT1014MJB?

A: Both devices are Texas Instruments products with identical electrical specifications and package format. The primary distinction is product designation; both offer active product status, ROHS3 compliance, and full compatibility with the obsolete LT1014MJ. Selection between these two substitutes can be based on inventory availability and supplier preference.

Q: Does the improved input bias current (12 nA) in substitute parts affect circuit performance compared to the LT1014MJ (15 nA)?

A: The lower input bias current in substitute parts represents an improvement in performance characteristics. Applications designed for the LT1014MJ will operate with equal or better performance using substitutes with 12 nA input bias current. No circuit redesign is required.

Q: Are all substitute parts RoHS compliant?

A: Yes, all three substitute parts (LT1014AMJB, LT1014DIN, and LT1014MJB) are ROHS3 compliant. The original LT1014MJ does not specify RoHS status. For applications requiring RoHS compliance, any of the three substitutes are suitable.
