Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL9008AIECZ-T are qualified based on the following criteria:

• Fixed output voltage of 1.8V
• Identical package type: 5-TSSOP (SC-70-5, SOT-353)
• Surface mount mounting type
• Output current rating equal to or greater than 150mA
• Maximum input voltage compatible with 6.5V or lower
• Active product status
• RoHS3 compliance
• Positive output configuration with single regulator

The three identified substitutes meet these core requirements while offering variations in output current capacity, quiescent current, and thermal performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and full RoHS3 compliance, ensuring regulatory and supply chain continuity with the ISL9008AIECZ-T.

AP2125KS-1.8TRG1 provides doubled output current capacity (300mA) in the same package footprint, suitable for applications requiring higher current delivery. Input voltage maximum is reduced to 6V, requiring verification against circuit input specifications.

TLV70018DCKR and TLV70018DCKT are functionally identical variants differing only in packaging format (Cut Tape & Digi-Reel versus standard tape & reel). Both offer 200mA output current, lower quiescent current (55 µA versus 66 µA), and extended operating temperature range to 125°C. Input voltage maximum is 5.5V, requiring circuit input verification. Both include reverse polarity protection not present in the original part.

Selection between substitutes depends on circuit input voltage requirements, desired output current margin, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can AP2125KS-1.8TRG1 directly replace ISL9008AIECZ-T?

A: Yes, within electrical constraints. The AP2125KS-1.8TRG1 maintains identical output voltage (1.8V), package type (SC-70-5), and mounting configuration. The maximum input voltage is reduced from 6.5V to 6V. Output current is increased to 300mA, providing additional capacity margin. Verify circuit input voltage does not exceed 6V.

Q: What is the difference between TLV70018DCKR and TLV70018DCKT?

A: Both parts are electrically identical with 1.8V output, 200mA current, and SC-70-5 package. The difference is packaging format: DCKR uses Cut Tape & Digi-Reel, while DCKT uses standard Cut Tape & Digi-Reel. Selection depends on procurement and assembly equipment compatibility.

Q: Are all substitutes pin-compatible with ISL9008AIECZ-T?

A: Yes. All substitute parts use the 5-TSSOP (SC-70-5, SOT-353) package with identical pinout configuration, enabling direct PCB footprint compatibility.

Q: Which substitute offers the lowest quiescent current?

A: TLV70018DCKR and TLV70018DCKT both offer 55 µA quiescent current, compared to 66 µA for the ISL9008AIECZ-T, providing 17% reduction in standby power consumption.

Q: Do all substitutes include UVLO protection?

A: ISL9008AIECZ-T, TLV70018DCKR, and TLV70018DCKT include Under Voltage Lockout (UVLO) protection. AP2125KS-1.8TRG1 does not include UVLO, featuring only Over Current and Over Temperature protection.

Q: What is the maximum operating temperature for each part?

A: ISL9008AIECZ-T and AP2125KS-1.8TRG1 operate to 85°C. TLV70018DCKR and TLV70018DCKT extend to 125°C, providing wider thermal operating range for high-temperature applications.
