Substitute Part Grouping Explanation

Substitution of the ZRT100GC1TC is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Type: Fixed
• Voltage - Output: 9.8V
• Current - Output: 30 mA
• Tolerance: ±1%
• Temperature Coefficient: 50ppm/°C
• Noise - 0.1Hz to 10Hz: 50µVp-p
• Current - Cathode: 150 µA
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: TO-261-4, TO-261AA
• Supplier Device Package: SOT-223-3

The ZRT100GC1TA meets all electrical and mechanical specifications required for direct substitution. Both devices share identical functional parameters and packaging, differing only in compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

The ZRT100GC1TA provides electrical and mechanical equivalence to the ZRT100GC1TC. Selection between these parts depends on compliance requirements:

• ZRT100GC1TC: Use when ROHS3 compliance is mandatory for the application or end-market.
• ZRT100GC1TA: Use when RoHS compliance is not a design constraint. This part is electrically and mechanically identical and maintains REACH Unaffected status.

Both devices carry identical ECCN and HTSUS classifications, ensuring consistent regulatory treatment in export and import scenarios.

Frequently Asked Questions (FAQ)

Q: Can ZRT100GC1TA replace ZRT100GC1TC in all applications?

A: Yes, from an electrical and mechanical standpoint. The ZRT100GC1TA matches all functional parameters, voltage output, current ratings, temperature coefficient, noise specifications, and package configuration. The difference is RoHS compliance status. Substitution is valid where RoHS3 compliance is not required.

Q: What is the primary difference between these two parts?

A: The ZRT100GC1TC is ROHS3 compliant, while the ZRT100GC1TA is RoHS non-compliant. All other specifications, including electrical performance and packaging, are identical.

Q: Are the packages physically interchangeable?

A: Yes. Both parts use the SOT-223-3 supplier device package with TO-261-4 and TO-261AA case designations. Pin configuration and footprint are identical, allowing direct PCB substitution.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any export or import restrictions for these parts?

A: Both parts are classified as EAR99 under ECCN and share the same HTSUS code (8542.39.0001), ensuring consistent regulatory treatment across international transactions.
