Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5372IUZ is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Amplifier Type: Differential
• Number of Circuits: 3
• Output Type: Differential
• Package / Case: 24-SSOP (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply Span: 4.75V to 11V
• Operating Temperature Range: -40°C to 85°C

Performance Parameters (Allowable Variation): Substitute parts may exhibit different values for slew rate, gain bandwidth product, -3dB bandwidth, input bias current, input offset voltage, supply current, and output current per channel, provided the substitute part maintains functional compatibility within the specified supply voltage and temperature operating ranges.

The EL5375IUZ qualifies as a substitute part based on matching the mandatory equivalence criteria while offering enhanced performance characteristics in bandwidth and slew rate specifications.

Parameter Comparison

Engineering Selection Recommendations

EL5372IUZ Primary Application: The EL5372IUZ remains the original specification part for designs requiring the stated performance envelope. Both the EL5372IUZ and EL5375IUZ are classified as obsolete products, requiring component sourcing from existing inventory channels.

EL5375IUZ as Substitute: The EL5375IUZ is electrically compatible with the EL5372IUZ for applications where the following conditions are met:

1. The design operates within the common supply voltage range of 4.75V to 11V
2. The operating temperature range of -40°C to 85°C is maintained
3. The 24-SSOP package footprint and surface mount assembly process are unchanged
4. The application tolerates the performance differences outlined in the parameter comparison table

The EL5375IUZ offers superior bandwidth characteristics (550 MHz -3dB bandwidth versus 250 MHz) and faster slew rate (900 V/µs versus 700 V/µs), making it suitable for applications requiring higher frequency response. The EL5375IUZ exhibits lower input offset voltage (3 mV versus 7 mV), beneficial for precision measurement circuits.

Both parts maintain ROHS3 compliance and identical moisture sensitivity specifications, ensuring compatibility with current manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the EL5375IUZ directly replace the EL5372IUZ in existing PCB designs?

A: Yes, the EL5375IUZ is pin-compatible and package-compatible with the EL5372IUZ. Both devices use the 24-SSOP package with identical pinout and footprint. No PCB modifications are required for physical substitution.

Q: What are the key performance differences between these parts?

A: The EL5375IUZ provides enhanced bandwidth performance with a -3dB bandwidth of 550 MHz compared to 250 MHz for the EL5372IUZ. The slew rate is increased from 700 V/µs to 900 V/µs. Input offset voltage is improved to 3 mV from 7 mV. Supply current consumption increases from 5.6 mA to 9.6 mA across the three channels. Output current per channel decreases from 95 mA to 67 mA.

Q: Are both parts RoHS compliant?

A: Yes, both the EL5372IUZ and EL5375IUZ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components?

A: Both parts are rated MSL 3 (168 Hours), indicating standard moisture sensitivity handling requirements for surface mount components. Storage and handling must follow IPC-A-610 guidelines for MSL 3 devices.

Q: Since both parts are obsolete, what should be considered for long-term supply?

A: Both the EL5372IUZ and EL5375IUZ are classified as obsolete products. Component selection should prioritize available inventory from authorized distributors. The EL5375IUZ currently has 1320 pieces in stock, while the EL5372IUZ has 2197 pieces available. For designs requiring long-term production support, evaluation of current-generation differential amplifier alternatives from Renesas Electronics Corporation or other manufacturers is recommended.

Q: Can the EL5375IUZ be used in applications originally designed for the EL5372IUZ without circuit modifications?

A: The EL5375IUZ is electrically compatible within the specified supply voltage (4.75V to 11V) and operating temperature (-40°C to 85°C) ranges. The enhanced performance characteristics of the EL5375IUZ do not create incompatibility with designs specified for the EL5372IUZ. However, circuit validation should confirm that the improved bandwidth and slew rate do not introduce unintended signal coupling or stability issues in the specific application context.
