Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZRT040GC1TC is determined by strict equivalence across the following critical parameters:

• Reference voltage output: 4.01V fixed
• Output current capability: 75 mA
• Voltage tolerance: ±1%
• Temperature coefficient: 50ppm/°C
• Noise specification: 50µVp-p (0.1Hz to 10Hz)
• Cathode current: 150 µA
• Operating temperature range: -40°C to 85°C
• Package type: SOT-223-3 surface mount
• Compliance standards: ROHS3, REACH Unaffected

The ZRT040GC1TA meets all these parameters and qualifies as a parametric equivalent. Substitution is valid when these electrical and mechanical specifications are maintained across the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The ZRT040GC1TA is the direct parametric equivalent for the obsolete ZRT040GC1TC. Both parts are manufactured by Diodes Incorporated and maintain identical electrical specifications and physical packaging. The ZRT040GC1TA carries Last Time Buy status, indicating limited future availability. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for current production environments. Selection between these parts should be based on inventory availability and supply chain planning, as the ZRT040GC1TA represents the final procurement opportunity for this reference voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the ZRT040GC1TA directly replace the ZRT040GC1TC in existing designs?

A: Yes. The ZRT040GC1TA is a parametric equivalent with identical electrical specifications (4.01V output, 75 mA current, ±1% tolerance, 50ppm/°C temperature coefficient) and identical SOT-223-3 packaging. No circuit modifications are required.

Q: What is the difference between ZRT040GC1TC and ZRT040GC1TA?

A: The primary difference is product status. The ZRT040GC1TC is obsolete, while the ZRT040GC1TA is Last Time Buy. Both parts share identical electrical and mechanical specifications. The packaging designation differs (TC vs. TA suffix), but both use SOT-223-3 surface mount packages.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory requirements are equivalent.

Q: What should be considered when transitioning from ZRT040GC1TC to ZRT040GC1TA?

A: The ZRT040GC1TA has limited availability due to Last Time Buy status. Procurement planning should account for this constraint. No technical design changes are necessary due to complete parametric equivalence.

Q: Are there any package or pinout differences?

A: No. Both parts use identical TO-261-4 and TO-261AA package designations with SOT-223-3 supplier device packaging. Pinout and PCB footprint compatibility is maintained.
