Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS3619-33MDGKREP is determined by strict equivalence across the following critical parameters:

Core Functional Parameters (Must Match):

• Single voltage monitoring channel
• 2.93V threshold voltage
• Push-pull, totem pole output
• Active-low reset with 60ms minimum timeout
• 8-TSSOP/8-MSOP package footprint
• Surface mount configuration

Acceptable Variations:

• Operating temperature range (wider ranges are acceptable for designs requiring -55°C to 125°C operation)
• Packaging format (Cut Tape vs. Tape & Reel)
• Product status (Last Time Buy to Active transition)
• Base product number within TPS3619/TPS3620 series

All substitute parts maintain identical electrical specifications, compliance certifications (ROHS3, REACH Unaffected, EAR99), and moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

TPS3619-33DGKR is the manufacturer-recommended substitute. This part maintains identical electrical and functional specifications with the exception of operating temperature range (-40°C to 85°C versus -55°C to 125°C). Selection of this part is appropriate for applications operating within the -40°C to 85°C envelope. The part is in Active product status with higher inventory availability (16,400 units).

TPS3620-33MDGKREP and TPS3620-33MDGKTEP are parametric equivalents offering full operating temperature range compatibility (-55°C to 125°C). Both parts are in Active product status. The primary distinction between these options is packaging format: TPS3620-33MDGKREP is supplied in Tape & Reel format with 2,250 units available, while TPS3620-33MDGKTEP is also Tape & Reel format with 3,899 units available. These parts are suitable for designs requiring extended temperature operation and high-volume tape and reel packaging.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TPS3619-33DGKR be used as a direct replacement for TPS3619-33MDGKREP?

A: TPS3619-33DGKR is functionally equivalent with one parameter difference: operating temperature range. The substitute operates from -40°C to 85°C, while the main part operates from -55°C to 125°C. Direct substitution is valid only if your application operates within the -40°C to 85°C temperature window.

Q: What is the difference between TPS3620-33MDGKREP and TPS3620-33MDGKTEP?

A: Both parts are parametric equivalents with identical electrical specifications and full -55°C to 125°C operating range. The difference is in packaging designation within the Tape & Reel format. Both are suitable for high-volume production environments.

Q: Are all substitute parts pin-compatible with the original TPS3619-33MDGKREP?

A: Yes. All substitute parts use the 8-TSSOP/8-MSOP package with identical 0.118" width and 3.00mm dimensions, ensuring PCB footprint compatibility.

Q: Why would I choose Tape & Reel packaging over Cut Tape?

A: Tape & Reel packaging (TPS3620 variants) is optimized for automated assembly processes and high-volume production runs. Cut Tape packaging is suitable for lower-volume applications and manual assembly workflows.

Q: Do all parts meet the same compliance requirements?

A: Yes. All parts listed are ROHS3 compliant, REACH Unaffected, classified as EAR99, and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Which substitute should I select for a new design?

A: For new designs, select from the Active status parts: TPS3619-33DGKR (if -40°C to 85°C operation is acceptable) or TPS3620-33MDGKREP/TPS3620-33MDGKTEP (if full -55°C to 125°C range is required). The main part TPS3619-33MDGKREP is in Last Time Buy status and should be reserved for legacy product support.
