TPS2491DGSG4 Equivalent & Substitute Parts

Part Overview

The TPS2491DGSG4 is a Hot Swap Controller designed for general-purpose applications, featuring 1 channel with programmable current limit, fault timeout, and UVLO (Under-Voltage Lock-Out) capabilities. Operating across a 9V to 80V supply voltage range, this component is packaged in a 10-VSSOP surface-mount configuration.

The TPS2491DGSG4 has been discontinued at DiGi Electronics. Locating equivalent or substitute parts is necessary to maintain design continuity and ensure project timelines are not compromised. Active alternatives with identical electrical and mechanical specifications are available.

Substitute Part Grouping Explanation

The TPS2491DGS qualifies as a direct substitute for the TPS2491DGSG4 based on the following criteria:

Electrical Equivalence:

• Identical supply voltage range (9V ~ 80V)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical supply current (1 mA)
• Identical programmable features (Current Limit, Fault Timeout, UVLO)
• Single channel configuration maintained

Mechanical Equivalence:

• Identical package type (10-VSSOP)
• Identical physical dimensions (10-TFSOP, 10-MSOP, 0.118", 3.00mm Width)
• Surface mount mounting type preserved

Compliance Equivalence:

• ROHS3 Compliant
• MSL Rating 2 (1 Year)
• REACH Unaffected
• ECCN EAR99

Parameter Comparison

Engineering Selection Recommendations

The TPS2491DGS is the direct substitute for the discontinued TPS2491DGSG4. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction is product status: the TPS2491DGS maintains active availability, whereas the TPS2491DGSG4 has been discontinued.

Selection of the TPS2491DGS ensures:

• Full electrical and functional compatibility
• Identical PCB footprint and assembly requirements
• Maintained ROHS3 compliance and MSL rating
• Continued access to active inventory

Frequently Asked Questions (FAQ)

Q: Can the TPS2491DGS be used as a direct replacement for the TPS2491DGSG4?

A: Yes. Both parts are electrically and mechanically identical. The TPS2491DGS is the active equivalent with the same supply voltage range (9V ~ 80V), operating temperature (-40°C ~ 85°C), channel configuration, programmable features, and 10-VSSOP package.

Q: Are there any PCB layout or assembly changes required when switching to the TPS2491DGS?

A: No. The TPS2491DGS uses the identical 10-VSSOP package with the same physical dimensions (0.118", 3.00mm Width). PCB footprints and assembly processes remain unchanged.

Q: What is the difference between the TPS2491DGSG4 and TPS2491DGS part numbers?

A: The difference lies in packaging and product status. The TPS2491DGSG4 was discontinued, while the TPS2491DGS remains in active production. Both share the same die and electrical characteristics.

Q: Are compliance certifications identical between these parts?

A: Yes. Both the TPS2491DGSG4 and TPS2491DGS carry ROHS3 compliance, MSL Rating 2 (1 Year), REACH Unaffected status, and ECCN EAR99 classification.

Q: What is the supply current specification for these parts?

A: Both parts operate at 1 mA supply current across the full 9V to 80V supply voltage range.
