Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV272IP is determined by the following critical parameters:

Mechanical Compatibility:

• Identical package configuration: 8-DIP (0.300", 7.62mm)
• Identical mounting type: Through Hole
• Identical circuit count: 2 circuits per package

Electrical Compatibility:

• Output type: Rail-to-Rail (required for direct substitution)
• Supply voltage range overlap: Minimum 2.7 V to maximum 16 V
• Operating temperature range: Must support the application's thermal requirements

Compliance Requirements:

• RoHS3 compliance status
• REACH compliance status
• ECCN and HTSUS classifications

The ICL7621BCPA+ meets the mechanical and electrical compatibility criteria through identical package geometry, dual-circuit configuration, and rail-to-rail output capability. Both parts operate within overlapping supply voltage ranges (2.7 V to 16 V for TLV272IP; 2 V to 16 V for ICL7621BCPA+) and maintain equivalent RoHS3 and REACH compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TLV272IP remains the preferred component when the application requires:

• Operating temperatures below 0°C or above 70°C
• Higher slew rate performance (2.6 V/µs vs. 1.6 V/µs)
• Higher gain bandwidth product (3 MHz vs. 1.4 MHz)
• Lower input offset voltage (500 µV vs. 5 mV)
• Lower supply current consumption (550 µA vs. 1 mA per dual channels)

Substitute Selection Criteria:

The ICL7621BCPA+ is suitable as a substitute when:

• Operating temperature range is limited to 0°C ~ 70°C
• Application bandwidth requirements do not exceed 1.4 MHz
• Input offset voltage specification of 5 mV is acceptable
• Supply voltage minimum of 2 V is sufficient (vs. 2.7 V minimum for TLV272IP)
• Higher supply current consumption (1 mA) is acceptable

Compliance Verification:

Both parts maintain identical RoHS3 and REACH compliance status, ensuring regulatory equivalence for applications subject to these standards. Both parts carry ECCN EAR99 and HTSUS 8542.33.0001 classifications.

Frequently Asked Questions (FAQ)

Q: Can the ICL7621BCPA+ be used as a direct pin-for-pin replacement for the TLV272IP?

A: Yes, both devices share identical 8-DIP package geometry and through-hole mounting configuration. Pin compatibility is established through matching package specifications. However, electrical performance differences must be evaluated against application requirements.

Q: What are the key electrical differences between these two parts?

A: The TLV272IP provides higher slew rate (2.6 V/µs vs. 1.6 V/µs), higher gain bandwidth product (3 MHz vs. 1.4 MHz), lower input offset voltage (500 µV vs. 5 mV), and lower supply current consumption (550 µA vs. 1 mA per dual channels). The ICL7621BCPA+ operates at a lower minimum supply voltage (2 V vs. 2.7 V).

Q: Are there temperature range limitations when substituting the ICL7621BCPA+ for the TLV272IP?

A: Yes. The ICL7621BCPA+ operating temperature range is 0°C ~ 70°C, compared to the TLV272IP range of -40°C ~ 125°C. Applications requiring operation outside the 0°C ~ 70°C window must use the TLV272IP.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the TLV272IP and ICL7621BCPA+ are ROHS3 compliant and REACH unaffected, with identical ECCN and HTSUS classifications.

Q: What packaging options are available for these parts?

A: Both parts are supplied in 8-DIP (0.300", 7.62mm) through-hole packages in tube packaging format.

Q: Which part should be selected for low-power applications?

A: The TLV272IP is the preferred choice for low-power applications, consuming 550 µA across both channels compared to 1 mA for the ICL7621BCPA+.

Q: Are there bandwidth limitations when using the ICL7621BCPA+ as a substitute?

A: The ICL7621BCPA+ has a gain bandwidth product of 1.4 MHz compared to 3 MHz for the TLV272IP. Applications requiring bandwidth above 1.4 MHz must use the TLV272IP.
