Key Parameters

Substitute Part Grouping Explanation

Substitute components for the AP3064AMTR-G1 must satisfy the following core electrical and mechanical criteria:

Primary Substitution Criteria:

• DC DC Controller topology with Step-Up (Boost) configuration
• 4 output channels for LED driver application
• Supply voltage range compatibility: minimum 4.5V to maximum 33V
• Output voltage capability of 60V
• PWM dimming capability
• 16-SOIC package form factor
• Surface mount mounting type
• Operating temperature range of -40°C to 85°C or broader

Secondary Compatibility Factors:

• Output current per channel: 220mA or higher
• Switching frequency within 100kHz to 1MHz range
• RoHS3 compliance
• Moisture sensitivity level appropriate for production environment

Substitutes are grouped based on adherence to these parameters. Parts meeting all primary criteria are considered direct functional equivalents. Parts with enhanced specifications (higher current capacity, extended temperature range, or additional dimming modes) are acceptable substitutes provided they maintain backward compatibility with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

AL3065S16-13 (Diodes Incorporated): This part maintains identical package geometry (16-SOIC) and supply voltage specifications as the AP3064AMTR-G1. The AL3065S16-13 provides enhanced output current capacity (250mA versus 220mA per channel) and supports both analog and PWM dimming modes, offering functional expansion while preserving form factor compatibility. Both parts share Obsolete status and ROHS3 compliance. This substitute is suitable for direct board-level replacement when PCB layout and thermal management accommodate the higher current capability.

ISL97687IBZ (Renesas Electronics Corporation): This part maintains the 4-output Step-Up (Boost) topology and PWM dimming capability required for backlight applications. The ISL97687IBZ operates at a higher minimum supply voltage (9V versus 4.5V) and delivers lower output current per channel (160mA versus 220mA). The package form factor differs significantly (28-SOIC versus 16-SOIC), requiring PCB redesign. The part holds Active product status and supports extended operating temperature range (-40°C to 105°C). This substitute is applicable only when supply voltage constraints permit the 9V minimum and when PCB layout can accommodate the larger package footprint.

Frequently Asked Questions (FAQ)

Q: Can AL3065S16-13 be used as a direct replacement for AP3064AMTR-G1?

A: AL3065S16-13 is functionally compatible for direct board-level replacement. Both parts use identical 16-SOIC packaging, operate within the same supply voltage range (4.5V to 33V), and support PWM dimming for 4-channel LED driver applications. The AL3065S16-13 provides higher output current capacity (250mA per channel) and dual dimming modes (analog and PWM), making it a capable substitute. No PCB layout modifications are required.

Q: What are the limitations of ISL97687IBZ as a substitute?

A: ISL97687IBZ requires a minimum supply voltage of 9V, which is higher than the AP3064AMTR-G1 specification of 4.5V. This part also delivers lower output current per channel (160mA versus 220mA), potentially limiting brightness in high-current LED applications. The 28-SOIC package is significantly larger than the 16-SOIC original, necessitating PCB redesign. ISL97687IBZ is suitable only for applications where the higher minimum voltage and lower current capacity are acceptable, and where PCB space permits the larger package.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. AP3064AMTR-G1, AL3065S16-13, and ISL97687IBZ are all ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: What is the significance of product status (Obsolete vs. Active)?

A: AP3064AMTR-G1 and AL3065S16-13 are classified as Obsolete, indicating discontinued manufacturing and limited long-term availability. ISL97687IBZ maintains Active status, ensuring ongoing production and supply chain availability. For new designs or long-term production requirements, Active-status components provide superior supply security.

Q: Can ISL97687IBZ be used in applications requiring 4.5V minimum supply voltage?

A: No. ISL97687IBZ specifies a minimum supply voltage of 9V. Applications requiring operation below 9V must use AP3064AMTR-G1 or AL3065S16-13, both of which support 4.5V minimum supply voltage.

Q: How do dimming capabilities differ between these parts?

A: AP3064AMTR-G1 supports PWM dimming only. AL3065S16-13 and ISL97687IBZ support both analog and PWM dimming modes, providing additional flexibility for brightness control implementation. Applications using PWM dimming exclusively are compatible with all three parts.
