EL5244CYZ Equivalent & Substitute Parts

Part Overview

The EL5244CYZ is a voltage feedback amplifier manufactured by Renesas Electronics Corporation, configured as a dual-circuit (2-channel) operational amplifier in an 8-MSOP surface mount package. This device features rail-to-rail output capability and is designed for general-purpose analog signal conditioning applications requiring moderate bandwidth and slew rate performance.

The EL5244CYZ is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure long-term component availability for new production builds and field replacements. Alternative devices meeting the same electrical and mechanical specifications are available from active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5244CYZ is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 8-MSOP surface mount with 0.118" (3.00mm) width
• Pin count and footprint alignment

Electrical Compatibility:

• Dual-circuit configuration (2 independent amplifiers per package)
• Output type: Rail-to-rail capability
• Supply voltage range: Minimum 4.75 V to maximum 5.25 V
• Output current per channel: 90 mA
• Operating temperature range: -40°C to 85°C

Regulatory Compliance:

• RoHS3 compliance
• REACH unaffected status
• ECCN EAR99 classification

Substitute parts are grouped into two categories based on amplifier topology and performance characteristics:

Category 1: J-FET Amplifiers (LTC6269 Series) The LTC6269HMS8E-10#PBF, LTC6269HMS8E-10#TRPBF, LTC6269IMS8E-10#PBF, and LTC6269IMS8E-10#TRPBF devices are J-FET input operational amplifiers manufactured by Analog Devices Inc. These parts share the 8-MSOP package footprint and dual-circuit configuration. Variants differ in packaging format (Tube vs. Tape & Reel) and temperature rating (Industrial vs. Military grade).

Category 2: CMOS Voltage Feedback Amplifier (OPA2354 Series) The OPA2354AIDGKT is a CMOS voltage feedback amplifier manufactured by Texas Instruments. This device maintains the 8-MSOP package footprint, dual-circuit configuration, and rail-to-rail output type. It is available in Cut Tape and Digi-Reel packaging.

Engineering Selection Recommendations

For Direct Replacement in 5V Supply Applications:

The OPA2354AIDGKT is the primary substitute for the EL5244CYZ in applications requiring voltage feedback amplifier topology with rail-to-rail output. This device is manufactured by Texas Instruments and maintains active product status. The OPA2354AIDGKT is RoHS3 compliant and REACH unaffected, meeting the same regulatory requirements as the original part. The device supports the full 5V supply range of the EL5244CYZ and provides extended operating temperature capability to 125°C. The 8-VSSOP package is mechanically compatible with the 8-MSOP footprint for standard PCB layouts.

For Low Input Bias Current Applications:

The LTC6269 series devices (LTC6269HMS8E-10#PBF, LTC6269HMS8E-10#TRPBF, LTC6269IMS8E-10#PBF, LTC6269IMS8E-10#TRPBF) manufactured by Analog Devices Inc. are suitable substitutes when extremely low input bias current is required. All LTC6269 variants are active products with RoHS3 compliance and REACH unaffected status. These J-FET input amplifiers provide input bias current of 0.003 pA compared to 2 nA in the EL5244CYZ. The LTC6269 series supports the 5V supply range and delivers 90 mA output current per channel. Packaging variants include Tube (PBF) and Tape & Reel (TRPBF) options. Temperature-rated variants include Industrial grade (-40°C to 85°C) and Military grade (-40°C to 125°C) options.

Packaging and Inventory Considerations:

All substitute parts are available in active inventory. The OPA2354AIDGKT offers the highest inventory level (8800 units). LTC6269 variants range from 797 to 1300 units depending on packaging and temperature grade. Selection between packaging formats (Tube, Tape & Reel, Cut Tape) depends on production volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the OPA2354AIDGKT directly replace the EL5244CYZ on existing PCBs?

A: The OPA2354AIDGKT uses an 8-VSSOP package while the EL5244CYZ uses 8-MSOP. Both packages have 0.118" (3.00mm) width and compatible pin spacing for standard surface mount assembly. Pin-to-pin compatibility must be verified against the specific PCB layout and schematic. The devices are electrically compatible for 5V supply applications.

Q: What is the key difference between the LTC6269 variants?

A: The LTC6269 series is available in four packaging and temperature combinations. The "H" designation indicates Military temperature grade (-40°C to 125°C), while "I" indicates Industrial grade (-40°C to 85°C). The "#PBF" suffix indicates Tube packaging, while "#TRPBF" indicates Tape & Reel packaging. All variants share identical electrical specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The OPA2354AIDGKT and all LTC6269 variants are RoHS3 compliant and REACH unaffected, matching the regulatory status of the EL5244CYZ.

Q: What is the primary advantage of the LTC6269 over the OPA2354AIDGKT?

A: The LTC6269 series provides significantly lower input bias current (0.003 pA versus 3 pA in the OPA2354AIDGKT) and higher slew rate (1500 V/µs versus 150 V/µs). These characteristics make the LTC6269 suitable for high-impedance signal sources and fast transient applications.

Q: What is the primary advantage of the OPA2354AIDGKT over the LTC6269?

A: The OPA2354AIDGKT provides higher gain bandwidth product (100 MHz versus 60 MHz in the EL5244CYZ) and wider -3dB bandwidth (250 MHz). The OPA2354AIDGKT also features lower input offset voltage (2 mV versus 25 mV in the EL5244CYZ), making it suitable for precision analog signal conditioning.

Q: Can the LTC6269 operate at the minimum supply voltage of the EL5244CYZ?

A: The LTC6269 series supports a minimum supply voltage of 3.1 V, which is lower than the EL5244CYZ minimum of 4.75 V. Both devices support the maximum supply voltage of 5.25 V. The LTC6269 provides greater supply voltage flexibility for applications requiring lower supply rails.

Q: What is the moisture sensitivity level difference between the EL5244CYZ and substitute parts?

A: The EL5244CYZ and OPA2354AIDGKT both have Moisture Sensitivity Level 2 (1 Year shelf life). The LTC6269 series has Moisture Sensitivity Level 1 (Unlimited shelf life), providing superior moisture resistance and longer storage capability.

Q: Are there any temperature rating limitations when substituting the EL5244CYZ?

A: The EL5244CYZ operates from -40°C to 85°C. The OPA2354AIDGKT extends this range to 125°C. The LTC6269IMS8E-10 variants match the -40°C to 85°C range, while LTC6269HMS8E-10 variants extend to 125°C. Selection depends on the target application temperature requirements.
