Engineering Selection Recommendations

The ZRT100GC1TA is classified as obsolete. When sourcing this component, verify current inventory availability through authorized distributors. The part is RoHS non-compliant; designs requiring RoHS compliance must evaluate alternative shunt voltage reference ICs meeting the specified electrical parameters. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage and handling.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the ZRT100GC1TA? A: A valid substitute must maintain identical shunt reference type, fixed 9.8V output voltage, 30 mA output current capability, ±1% tolerance, 50ppm/°C temperature coefficient, and SOT-223-3 package configuration.

Q: Can I use a different output voltage shunt reference? A: No. The 9.8V fixed output is application-specific. Alternative voltage references are not substitutes for this component.

Q: Is the SOT-223-3 package interchangeable with other packages? A: The SOT-223-3 package is specified for this application. Package changes require PCB redesign and are not considered direct substitution.

Q: What is the impact of the RoHS non-compliant status? A: RoHS non-compliance may restrict use in applications or regions with RoHS mandates. Designs requiring RoHS compliance must source alternative components meeting both electrical specifications and RoHS requirements.

Q: How does the MSL rating affect component handling? A: MSL 1 (Unlimited) indicates no moisture sensitivity. Standard handling procedures apply without special moisture control requirements.
