PAM2306AYPBK Equivalent & Substitute Parts

Part Overview

The PAM2306AYPBK is a buck switching regulator IC manufactured by Diodes Incorporated, designed for positive fixed dual-output applications with 1.2V and 3.3V outputs. This device operates as a step-down converter with 1A output current capability and 1.5MHz switching frequency in a 12-WFDFN exposed pad surface mount package.

The PAM2306AYPBK is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this dual-output buck regulator topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAM2306AYPBK are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

• Dual-output buck regulator topology with positive fixed output configuration
• Input voltage range: 2.5V to 5.5V minimum and maximum
• Output current capability: 1A per output
• Switching frequency: 1.5MHz
• Synchronous rectifier implementation
• Operating temperature range: -40°C to 85°C
• Package type: 12-WFDFN exposed pad surface mount
• Regulatory compliance: ROHS3 compliant, REACH unaffected

The substitute parts identified (RT8020AGQW and RT8020BGQW) maintain identical electrical specifications for input voltage, output current, switching frequency, synchronous rectification, operating temperature, and package configuration. Output voltage variations (1.8V/3.3V and 1.3V/3.3V respectively) represent the primary design difference and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both RT8020AGQW and RT8020BGQW are active products from Richtek USA Inc., providing supply chain continuity for the obsolete PAM2306AYPBK. Selection between these substitutes depends on application-specific output voltage requirements:

RT8020AGQW provides 1.8V and 3.3V fixed outputs, suitable for applications requiring the higher 1.8V rail.

RT8020BGQW provides 1.3V and 3.3V fixed outputs, suitable for applications requiring the lower 1.3V rail.

Both substitutes maintain identical electrical performance across input voltage range, output current capability, switching frequency, and thermal operating range. Both are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original part.

Moisture sensitivity level differs between the original part (MSL 1, unlimited) and substitutes (MSL 3, 168 hours). This parameter affects storage and handling procedures and must be considered within supply chain and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can RT8020AGQW or RT8020BGQW be used as direct replacements for PAM2306AYPBK?

A: Both Richtek parts are functionally equivalent in topology, electrical performance, and package configuration. Direct substitution is possible when the output voltage requirements match the application design. RT8020BGQW (1.3V/3.3V) is the closest match to the original 1.2V/3.3V configuration.

Q: What is the primary difference between RT8020AGQW and RT8020BGQW?

A: The primary difference is the fixed output voltage of the lower rail: RT8020AGQW provides 1.8V while RT8020BGQW provides 1.3V. Both maintain identical 3.3V on the second output and share all other electrical and mechanical specifications.

Q: Are there package compatibility concerns?

A: No. All three parts use the 12-WFDFN exposed pad surface mount package with identical pinout and footprint requirements. PCB layout and assembly processes remain unchanged.

Q: How does the difference in Moisture Sensitivity Level (MSL) affect part selection?

A: The PAM2306AYPBK has MSL 1 (unlimited shelf life), while RT8020AGQW and RT8020BGQW have MSL 3 (168-hour limit after moisture exposure). This affects storage conditions and handling procedures. Parts with MSL 3 require baking before reflow if storage time exceeds 168 hours in standard humidity conditions.

Q: Are regulatory certifications equivalent?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for environmental and hazardous substance compliance.

Q: Which substitute should be selected for new designs?

A: RT8020BGQW is recommended for new designs requiring the 1.2V output specification, as its 1.3V output is the closest available match. RT8020AGQW is suitable when 1.8V output is acceptable for the application.
