Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with Diodes Incorporated and comply with ROHS3 and REACH requirements. Selection between AP2151AS-13, AP2151SG-13, and AP2145SG-13 is determined by moisture sensitivity requirements and packaging designation preferences.

AP2151AS-13 and AP2151SG-13 are functionally identical with MSL 1 (Unlimited) classification, differing only in supplier device package designation (8-SO). Both support unlimited shelf life under standard storage conditions.

AP2145SG-13 provides equivalent electrical performance with MSL 3 (168 Hours) classification, requiring controlled storage conditions. The MSL 3 designation indicates moisture sensitivity requiring bake-out procedures if storage exceeds 168 hours at 30°C/60% RH. This part is suitable for applications where moisture sensitivity constraints are acceptable.

Frequently Asked Questions (FAQ)

Q: Can AP2151SG-13 directly replace AP2151AS-13?

A: Yes. Both parts are electrically and mechanically equivalent with identical electrical specifications, operating parameters, and package dimensions. The difference in supplier device package designation (8-SO) does not affect functional compatibility.

Q: What is the primary difference between AP2151AS-13 and AP2145SG-13?

A: The primary difference is the Moisture Sensitivity Level (MSL). AP2151AS-13 has MSL 1 (Unlimited), while AP2145SG-13 has MSL 3 (168 Hours). All electrical parameters, output specifications, and thermal characteristics are identical. The MSL 3 classification requires adherence to moisture control procedures during storage and handling.

Q: Are all three parts suitable for USB power switching applications?

A: Yes. All three parts are classified as USB switches with identical P-channel high-side output configuration, 500mA maximum output current, and 2.7V to 5.5V load voltage range. They are functionally equivalent for USB power switching applications.

Q: What are the package compatibility considerations?

A: All three parts use 8-SOIC (0.154", 3.90mm Width) package dimensions with surface mount mounting type. PCB footprints and land patterns are compatible across all three parts. The supplier device package designations (8-SO and 8-SOP) refer to the same physical package form factor.

Q: Which part should be selected for long-term storage without moisture control?

A: AP2151AS-13 or AP2151SG-13 are recommended for applications requiring unlimited shelf life. Both have MSL 1 classification, eliminating the need for moisture control procedures during storage.

Q: Are there any compliance or certification differences between these parts?

A: All three parts are ROHS3 compliant and REACH unaffected. Compliance status is identical across all substitute options.
