Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP3607FNTR-G1 is determined by the following critical parameters:

• Number of Outputs: 6 outputs (primary functional requirement)
• Topology: Switched Capacitor (Charge Pump) or Step-Up (Boost) with equivalent voltage regulation capability
• Current - Output / Channel: Minimum 20mA per channel
• Voltage - Supply Range: Compatibility with 2.7V to 5.5V input or overlapping range
• Operating Temperature: -40°C to 85°C minimum
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

The substitute parts identified below meet these core electrical and mechanical requirements, though some offer enhanced specifications (higher current capacity, extended temperature range, or active product status).

Parameter Comparison

Engineering Selection Recommendations

ADM8843ACPZ-REEL7 (Analog Devices Inc.): This part maintains the switched capacitor topology and identical supply voltage range (2.6V to 5.5V) as the AP3607FNTR-G1. However, it provides only 4 outputs versus 6, making it suitable only for applications requiring reduced channel count. Product status is active with full manufacturing support.

MIC3263YML-TR (Microchip Technology): This part matches the 6-output requirement and exceeds current specifications (30mA per channel). It employs step-up (boost) topology with extended supply range (6V to 40V) and superior temperature rating (-40°C to 125°C). The larger 24-MLF package and higher minimum supply voltage (6V) require PCB layout and power supply design modifications. Product status is active.

TPS61187RTJR (Texas Instruments): This part provides 6 outputs with 30mA per-channel capacity using step-up (boost) topology. Supply range is 4.5V to 24V with specified 38V output voltage. Operating temperature matches the original (-40°C to 85°C). Package is 20-QFN (4x4), requiring board redesign. Product status is active with full manufacturing support.

All substitute parts carry ROHS3 compliance and EAR99 classification, meeting regulatory requirements equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can ADM8843ACPZ-REEL7 directly replace AP3607FNTR-G1 in existing designs?

A: Direct replacement is not recommended. The ADM8843ACPZ-REEL7 provides only 4 outputs compared to the 6 outputs of the AP3607FNTR-G1. Applications requiring all 6 LED driver channels will require circuit redesign or use of multiple ADM8843 devices.

Q: What is the primary difference between the AP3607FNTR-G1 and the boost topology substitutes?

A: The AP3607FNTR-G1 uses switched capacitor (charge pump) topology, which operates efficiently at low input voltages (2.7V minimum). The MIC3263YML-TR and TPS61187RTJR employ step-up (boost) topology, requiring higher minimum input voltages (6V and 4.5V respectively) but offering extended supply ranges and higher output current capability.

Q: Are package changes required when substituting these parts?

A: Yes. The AP3607FNTR-G1 uses 16-VFQFN (3x3) packaging. The ADM8843ACPZ-REEL7 uses 16-VFQFN-VQ (3x3) with compatible footprint. The MIC3263YML-TR requires 24-MLF (4x4) and the TPS61187RTJR requires 20-QFN (4x4), both necessitating PCB layout modifications.

Q: Which substitute part is most suitable for low-voltage applications below 4.5V?

A: The ADM8843ACPZ-REEL7 maintains the lowest minimum supply voltage (2.6V) among active alternatives, making it the only viable option for applications operating below 4.5V. However, the reduced output count (4 versus 6) must be accommodated in the design.

Q: Do all substitute parts maintain the same operating temperature range?

A: The ADM8843ACPZ-REEL7 and TPS61187RTJR maintain -40°C to 85°C operation. The MIC3263YML-TR extends the upper limit to 125°C (junction temperature), providing enhanced thermal margin for high-temperature environments.

Q: What is the moisture sensitivity impact when selecting substitutes?

A: The AP3607FNTR-G1 and ADM8843ACPZ-REEL7 both carry MSL 3 (168 hours). The MIC3263YML-TR and TPS61187RTJR carry MSL 2 (1 year), indicating superior moisture resistance and extended shelf life without baking requirements.
