AP7342D-2812FS6-7 Equivalent & Substitute Parts

Part Overview

The AP7342D-2812FS6-7 is a linear voltage regulator IC from Diodes Incorporated designed for dual-output power management applications. This device provides two independent fixed voltage outputs (1.2V and 2.8V) with 150mA per channel in a compact 6-pin X2-DFN1212-6 surface mount package. The part is currently in Last Time Buy status, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP7342D-2812FS6-7 is determined by the following critical parameters:

• Output voltage configuration (1.2V and 2.8V fixed outputs required)
• Dual-output positive regulator topology
• Maximum input voltage rating of 5.25V or higher
• Operating temperature range of -40°C to 85°C or wider
• Surface mount packaging with exposed pad design
• RoHS3 compliance and MSL Level 1 rating
• Enable control feature availability

The AP7345D-2812RH4-7 qualifies as a substitute based on matching output voltage configuration, dual-output topology, input voltage rating, operating temperature range, surface mount construction, and compliance certifications. While the substitute offers enhanced specifications (higher output current, improved dropout voltage on one channel, additional protection features), these represent functional improvements rather than deviations from the core substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-2812RH4-7 is an active product from the same manufacturer with equivalent core functionality and superior availability. Both devices maintain identical output voltage specifications, input voltage ratings, operating temperature ranges, and compliance certifications (ROHS3, MSL Level 1, REACH Unaffected, EAR99).

The primary design consideration is package footprint change from 6-pin X2-DFN1212-6 to 8-pin X2-DFN1612-8. This requires PCB layout modification but provides increased output current capacity (300mA versus 150mA per channel) and enhanced protection features (Short Circuit protection in addition to Over Current protection).

For applications requiring the exact 150mA output current specification of the original part, the substitute's higher current rating presents no functional limitation and provides design margin. The substitute's active product status ensures long-term availability and manufacturing support compared to the Last Time Buy status of the AP7342D-2812FS6-7.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-2812RH4-7 directly replace the AP7342D-2812FS6-7 without circuit modifications?

A: The substitute provides identical output voltages and input voltage specifications. However, the package change from 6-pin to 8-pin requires PCB layout redesign. The footprint dimensions differ (X2-DFN1212-6 versus X2-DFN1612-8), necessitating new land pattern design and component placement.

Q: What are the key differences in electrical performance?

A: The substitute offers doubled output current capacity (300mA versus 150mA per channel), improved dropout voltage on the 2.8V channel (0.3V at 300mA versus 0.3V at 150mA), and additional Short Circuit protection. Quiescent current increases from 100 µA to 140 µA. PSRR and operating temperature range remain identical.

Q: Are both parts RoHS and REACH compliant?

A: Both the AP7342D-2812FS6-7 and AP7345D-2812RH4-7 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: Why is the original part in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The AP7345D-2812RH4-7 remains in Active status, making it the recommended choice for new designs and ongoing production requirements.

Q: Does the higher quiescent current of the substitute affect power consumption?

A: The quiescent current increase from 100 µA to 140 µA represents a 40 µA difference. For most applications, this 0.04mA increase is negligible compared to the load current drawn by the 150mA or 300mA output channels.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity limitations. Components can be stored indefinitely without desiccant packaging or time-to-reflow restrictions.
