Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Output Type: N-Channel or P-Channel configuration
• Output Configuration: High Side switching
• Voltage - Load: 2.7V ~ 5.5V operating range
• Current - Output (Max): Minimum 1A capacity
• Rds On (Typ): Comparable on-resistance (70mOhm reference)
• Interface: On/Off control
• Input Type: Non-Inverting
• Features: Status Flag capability
• Fault Protection: Current Limiting, Over Temperature, UVLO
• Package / Case: 8-TSSOP or 8-MSOP form factor
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories: direct parametric equivalents (identical specifications) and manufacturer-recommended alternatives (functionally compatible with specified parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent:

TPS2065DGNR is the primary substitute for TPS2065DGNRG4. Both parts share identical electrical specifications including 1A output current, 70mOhm on-resistance, and 2.7V ~ 5.5V load voltage range. The TPS2065DGNR maintains active product status with improved MSL rating (1 vs. 2) and unlimited moisture sensitivity duration. Packaging and RoHS compliance are equivalent.

Rohm Semiconductor N-Channel Alternatives:

BD82065FVJ-LBE2, BD82028FVJ-GE2, BD82030FVJ-GE2, and BD82034FVJ-GE2 provide N-Channel high-side switching with comparable on-resistance (70-72mOhm). These parts are active with ROHS3 compliance. BD82028FVJ-GE2 and BD82030FVJ-GE2 operate within 4.5V ~ 5.5V load voltage range (narrower than TPS2065DGNRG4). BD82034FVJ-GE2 supports 2.5A output current. All Rohm parts include additional load discharge feature and reverse current protection.

Diodes Incorporated P-Channel Alternatives:

AP2151MPG-13, AP2171MPG-13, and AP2191MPG-13 are P-Channel high-side switches with 2.7V ~ 5.5V load voltage compatibility. These parts feature 500mA, 1A, and 1.5A output current ratings respectively. All maintain active status with ROHS3 compliance and unlimited MSL duration. P-Channel topology requires inverted control logic compared to N-Channel TPS2065DGNRG4.

Frequently Asked Questions (FAQ)

Q: Can TPS2065DGNR directly replace TPS2065DGNRG4 without circuit modification?

A: Yes. TPS2065DGNR is a parametric equivalent with identical electrical specifications, package form factor, and control interface. The only differences are improved MSL rating and active product status.

Q: What are the key differences between N-Channel and P-Channel substitutes?

A: N-Channel devices (TPS2065DGNR, BD82065FVJ-LBE2, BD82028FVJ-GE2, BD82030FVJ-GE2, BD82034FVJ-GE2) and P-Channel devices (AP2151MPG-13, AP2171MPG-13, AP2191MPG-13) require opposite control logic. N-Channel switches activate with high input signal; P-Channel switches activate with low input signal. Circuit redesign is necessary for P-Channel substitution.

Q: Why do some Rohm parts specify 4.5V ~ 5.5V load voltage instead of 2.7V ~ 5.5V?

A: BD82028FVJ-GE2, BD82030FVJ-GE2, and BD82034FVJ-GE2 are optimized for USB Switch applications with narrower voltage specification. These parts are not suitable for applications requiring 2.7V ~ 3.3V operation.

Q: What is the significance of the 70mOhm vs. 95mOhm on-resistance difference?

A: On-resistance directly affects power dissipation and thermal performance. Lower on-resistance (70mOhm) generates less heat at equivalent current levels. Diodes Incorporated P-Channel parts with 95mOhm on-resistance may require thermal analysis for high-current applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original TPS2065DGNRG4 environmental specification.

Q: What packaging considerations apply to these substitutes?

A: All parts use 8-TSSOP or 8-MSOP form factors with 0.118" (3.00mm) width. PCB footprints are compatible across all listed substitutes. Exposed pad variants (TPS2065DGNR, AP2151MPG-13, AP2171MPG-13, AP2191MPG-13) provide improved thermal performance through ground connection.

Q: Which substitute offers the highest current capacity?

A: BD82034FVJ-GE2 supports 2.5A output current, exceeding the 1A specification of TPS2065DGNRG4. This part is suitable for applications requiring higher current switching capability within the 4.5V ~ 5.5V load voltage range.
