PAM2306AYPKB Equivalent & Substitute Parts

Part Overview

The PAM2306AYPKB is a buck switching regulator IC manufactured by Diodes Incorporated, designed for dual-output power management applications. This device provides fixed output voltages of 1.2V and 3.3V with 1A output current capability in a 12-WFDFN surface mount package. The PAM2306AYPKB is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAM2306AYPKB are selected based on the following critical parameters that determine functional compatibility:

• Topology & Function: Buck (step-down) switching regulator with dual fixed outputs
• Package Compatibility: 12-WFDFN Exposed Pad form factor for direct PCB footprint compatibility
• Output Configuration: Two independent positive fixed voltage outputs
• Electrical Specifications: Input voltage range 2.5V to 5.5V, 1A output current per channel, 1.5MHz switching frequency
• Synchronous Rectification: Integrated synchronous rectifier for efficiency
• Operating Temperature Range: -40°C to 85°C
• Compliance: ROHS3 compliance and EAR99 classification

The substitute parts listed below maintain these core parameters while offering different fixed output voltage combinations. Substitution is valid when the application circuit can accommodate the alternative output voltage values provided by the substitute device.

Parameter Comparison

Engineering Selection Recommendations

Both RT8020AGQW and RT8020BGQW are active product alternatives to the obsolete PAM2306AYPKB. These Richtek devices maintain identical electrical specifications, package form factor, and compliance certifications (ROHS3, EAR99).

RT8020AGQW provides output voltages of 1.8V and 3.3V. This substitute is applicable when the application circuit requires a 1.8V rail instead of the original 1.2V specification.

RT8020BGQW provides output voltages of 1.3V and 3.3V. This substitute is applicable when the application circuit requires a 1.3V rail instead of the original 1.2V specification.

Both substitutes carry an MSL rating of 3 (168 hours), compared to the original part's MSL rating of 1 (unlimited). This difference requires consideration of moisture handling procedures during storage and assembly operations.

Selection between RT8020AGQW and RT8020BGQW depends solely on which fixed output voltage (1.8V or 1.3V) aligns with the application's power distribution requirements.

Frequently Asked Questions (FAQ)

Q: Can RT8020AGQW or RT8020BGQW be used as direct replacements for PAM2306AYPKB?

A: Direct PCB footprint replacement is possible due to identical 12-WFDFN packaging. However, functional compatibility depends on whether the application circuit can operate with the alternative output voltage values (1.8V or 1.3V instead of 1.2V).

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

A: The primary difference is the lower fixed output voltage: RT8020AGQW provides 1.8V while RT8020BGQW provides 1.3V. Both maintain 3.3V on the second output channel.

Q: Are there any compliance or certification differences between the original and substitute parts?

A: All three parts are ROHS3 compliant and carry EAR99 classification. The substitute parts differ in MSL rating: PAM2306AYPKB is MSL 1 (unlimited), while both RT8020 variants are MSL 3 (168 hours).

Q: What does MSL 3 (168 hours) mean for manufacturing?

A: MSL 3 indicates the component can be exposed to moisture for a maximum of 168 hours at specified temperature and humidity conditions before soldering. Proper storage in dry conditions and adherence to moisture handling procedures is required.

Q: Are the electrical performance characteristics identical across all three parts?

A: Yes. Input voltage range (2.5V to 5.5V), output current (1A per channel), switching frequency (1.5MHz), synchronous rectification, and operating temperature range (-40°C to 85°C) are identical across PAM2306AYPKB, RT8020AGQW, and RT8020BGQW.

Q: Which substitute should be selected if the application requires a 1.2V output?

A: Neither RT8020AGQW nor RT8020BGQW provides a 1.2V output. RT8020BGQW at 1.3V is the closest alternative. Application circuit validation is required to confirm compatibility with this voltage deviation.
