Key Parameters

Substitute Part Grouping Explanation

The PAM2423AECADJR qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Identical manufacturer (Diodes Incorporated)
• Identical topology (Boost switching regulator)
• Identical output configuration (Positive adjustable)
• Identical input voltage range (2.7V to 5.5V)
• Identical output voltage range (2.7V to 24V)
• Identical switching frequency (520kHz)
• Identical package type (8-SOIC with exposed pad)
• Identical operating temperature range (-40°C to 85°C)
• Identical compliance certifications (ROHS3, MSL 1, REACH Unaffected)

Distinguishing Parameter:

• Output current (switch): PAM2422AECADJR = 4.5A; PAM2423AECADJR = 5.5A

The PAM2423AECADJR provides higher current capability while maintaining all other electrical and mechanical specifications, making it suitable for applications requiring equal or greater output current capacity.

Parameter Comparison

Engineering Selection Recommendations

The PAM2423AECADJR is the direct substitute for the obsolete PAM2422AECADJR. Selection of the PAM2423AECADJR is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical electrical specifications across input voltage, output voltage, switching frequency, and operating temperature range
• Identical package footprint and pinout compatibility (8-SOIC with exposed pad)
• Full compliance with ROHS3, REACH, and moisture sensitivity requirements
• Higher output current rating (5.5A versus 4.5A), providing design margin for existing applications

No design modifications are required for PCB layout or schematic implementation when transitioning from PAM2422AECADJR to PAM2423AECADJR.

Frequently Asked Questions (FAQ)

Q: Can PAM2423AECADJR directly replace PAM2422AECADJR without PCB modifications?

A: Yes. Both parts share identical pinout, package dimensions (8-SOIC with exposed pad), and electrical specifications for input voltage, output voltage, and switching frequency. No PCB layout changes are required.

Q: What is the primary difference between these two parts?

A: The output current (switch) rating differs: PAM2422AECADJR is rated for 4.5A, while PAM2423AECADJR is rated for 5.5A. All other parameters remain identical.

Q: Is the higher current rating of PAM2423AECADJR compatible with designs originally specified for PAM2422AECADJR?

A: Yes. The PAM2423AECADJR's higher current capability is fully compatible with applications designed for the lower-rated PAM2422AECADJR. No circuit modifications are necessary.

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

A: No. Both parts carry identical ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What is the availability status of each part?

A: PAM2422AECADJR is classified as obsolete. PAM2423AECADJR is active with high inventory availability, making it the recommended choice for new designs and production continuity.

Q: Are the thermal and operating characteristics identical?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C and share the same switching frequency of 520kHz.
