Substitute Part Grouping Explanation

Substitute parts for the AP2172MPG-13 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Diodes Incorporated): Parts AP2162MPG-13, AP2166MPG-13, and AP2176MPG-13 maintain identical electrical specifications including 1:2 output ratio, P-Channel configuration, High Side output, 2.7V ~ 5.5V load voltage range, 1A maximum output current, and 8-MSOP-EP package compatibility. These parts differ only in on-resistance (Rds On) values: AP2162MPG-13 and AP2172MPG-13 at 115mOhm, while AP2166MPG-13 and AP2176MPG-13 at 90mOhm. All maintain identical operating temperature range (-40°C ~ 85°C), RoHS3 compliance, and MSL 1 rating.

Manufacturer Recommended Alternatives (Texas Instruments): Parts TPS2062QDGNRQ1, TPS2064CDGN-2, TPS2064CDGNR-2, TPS2066CDGN-2, and TPS2066CDGNR-2 are N-Channel equivalents with identical 1:2 output ratio, High Side configuration, and 8-MSOP package footprint. These parts operate at 4.5V ~ 5.5V load voltage (narrower than the original 2.7V ~ 5.5V), feature lower on-resistance (70mOhm), extended operating temperature range (-40°C ~ 125°C), and automotive-grade qualification (AEC-Q100) with MSL 2 rating.

Key substitution parameters: Output ratio (1:2), output configuration (High Side), package type (8-MSOP), mounting type (Surface Mount), and interface (On/Off with Status Flag).

Parameter Comparison

Engineering Selection Recommendations

Diodes Incorporated P-Channel Substitutes (AP2162MPG-13, AP2166MPG-13, AP2176MPG-13): These parts maintain identical electrical and mechanical specifications to the AP2172MPG-13 with RoHS3 compliance and MSL 1 rating. Selection among these three depends on on-resistance requirements: AP2162MPG-13 and AP2172MPG-13 provide 115mOhm, while AP2166MPG-13 and AP2176MPG-13 provide improved 90mOhm performance. All three are Active status products suitable for direct substitution in non-automotive applications.

Texas Instruments N-Channel Alternatives (TPS2062QDGNRQ1, TPS2064 series, TPS2066 series): These parts offer extended operating temperature range (-40°C ~ 125°C) and lower on-resistance (70mOhm) with automotive-grade qualification (AEC-Q100). The TPS2062QDGNRQ1 maintains 1A output current matching the original specification. TPS2064 variants provide 1.5A output current with narrower load voltage range (4.5V ~ 5.5V). TPS2066 variants maintain 1A output current with identical load voltage constraints. MSL 2 rating requires one-year shelf life management. N-Channel topology requires circuit design review for compatibility with existing P-Channel control logic.

Selection criteria: Maintain P-Channel topology for direct substitution, or evaluate N-Channel alternatives only when circuit design permits channel-type conversion and extended temperature range is beneficial.

Frequently Asked Questions (FAQ)

Q: Can AP2162MPG-13, AP2166MPG-13, or AP2176MPG-13 be used as direct replacements for AP2172MPG-13?

A: Yes. All three Diodes Incorporated parts share identical electrical specifications including 1:2 output ratio, P-Channel configuration, High Side output, 2.7V ~ 5.5V load voltage range, 1A maximum output current, 8-MSOP-EP package, and RoHS3 compliance. Differences in on-resistance (115mOhm vs. 90mOhm) do not prevent substitution but may affect thermal performance in high-current applications.

Q: What is the primary difference between Diodes Incorporated and Texas Instruments substitutes?

A: Diodes Incorporated substitutes maintain P-Channel output topology and -40°C ~ 85°C operating temperature. Texas Instruments substitutes use N-Channel topology with extended -40°C ~ 125°C operating temperature and automotive-grade qualification (AEC-Q100). N-Channel substitution requires circuit design verification to confirm compatibility with existing control logic.

Q: Are Texas Instruments TPS2064 and TPS2066 parts compatible with the AP2172MPG-13 load voltage specification?

A: TPS2064 and TPS2066 parts operate at 4.5V ~ 5.5V load voltage, which is narrower than the original AP2172MPG-13 specification of 2.7V ~ 5.5V. These parts are not suitable for applications requiring operation below 4.5V load voltage.

Q: What packaging considerations apply to Texas Instruments substitutes?

A: Texas Instruments parts use 8-HVSSOP package versus the original 8-MSOP-EP package. Both are 8-pin surface mount packages with 0.118" (3.00mm) width and exposed pad thermal connection. PCB layout and thermal management may differ due to package variant differences.

Q: Does MSL rating affect part selection?

A: AP2172MPG-13 and Diodes Incorporated substitutes carry MSL 1 (Unlimited shelf life). Texas Instruments parts carry MSL 2 (1-year shelf life), requiring controlled storage conditions and floor-life management during assembly. This affects supply chain handling and component procurement planning.

Q: Can TPS2062QDGNRQ1 be used in non-automotive applications?

A: Yes. TPS2062QDGNRQ1 is automotive-grade qualified (AEC-Q100) but is not restricted to automotive use. It is suitable for general-purpose applications requiring extended temperature range and lower on-resistance.
