Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS3898ADRYR are determined by strict equivalence across all electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Single-channel voltage monitoring capability
• Adjustable/selectable voltage threshold
• Open drain or open collector output configuration
• Active low reset logic
• Adjustable/selectable reset timeout
• Operating temperature range of -40°C to 125°C

Mechanical Parameters (Must Match):

• 6-UFDFN package type
• 6-SON (1.45x1) supplier device package
• Surface mount mounting type

Compliance & Certification (Must Match):

• RoHS3 compliance
• MSL rating of 1 (Unlimited)
• REACH Unaffected status
• Active product status

The identified substitutes maintain identical functional specifications and compliance certifications. Variations in part numbering reflect differences in tape reel configurations or internal device programming, not electrical or mechanical characteristics.

Availability Considerations:

• TPS3898ADRYR: 30,100 pieces in stock
• TPS3898ADRYT: 2,600 pieces in stock
• TPS3898PDRYT: 2,970 pieces in stock

All parts carry Active product status, ensuring long-term availability and manufacturing support from Texas Instruments. All three maintain full RoHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Are TPS3898ADRYR, TPS3898ADRYT, and TPS3898PDRYT electrically interchangeable?

A: Yes. All three parts are electrically identical. They share the same single-channel voltage monitoring, adjustable threshold, open drain/open collector output, active low reset logic, and adjustable reset timeout specifications. Operating temperature range, package type, and all compliance certifications are identical.

Q: What is the difference between these part numbers?

A: The differences are limited to tape reel configurations and internal device programming variants. These variations do not affect electrical performance or mechanical compatibility in circuit applications.

Q: Can I substitute TPS3898ADRYT for TPS3898ADRYR in my design?

A: Yes. Both parts are pin-compatible, functionally equivalent, and maintain identical compliance certifications. No circuit modifications are required.

Q: Are all three parts RoHS3 compliant?

A: Yes. TPS3898ADRYR, TPS3898ADRYT, and TPS3898PDRYT all carry RoHS3 compliance certification and REACH Unaffected status.

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

A: All three parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Do these parts require different PCB layouts or soldering profiles?

A: No. All three parts use the identical 6-UFDFN package with 6-SON (1.45x1) supplier device package specification. PCB layouts, footprints, and soldering profiles are identical.

Q: Which part should I select for new designs?

A: Selection should be based on current inventory availability and supply chain lead times. All three parts are equally suitable for new designs from a technical standpoint.
