ADP3335ARMZ-1.8-RL Equivalent & Substitute Parts

Part Overview

The ADP3335ARMZ-1.8-RL is a linear voltage regulator IC from Analog Devices Inc., classified as a Power Management (PMIC) component. This device delivers a fixed 1.8V output at 500mA with a maximum dropout voltage of 0.37V, designed for surface mount applications in the 8-MSOP package. The part maintains Active product status and is ROHS3 compliant. Substitute parts may be required due to packaging format availability, inventory constraints, or supply chain considerations while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The ADP3335ARMZ-1.8-RL has one parametric equivalent substitute: ADP3335ARMZ-1.8-R7. Both parts share identical electrical specifications and mechanical characteristics. The substitution is valid based on the following key parameters:

• Output voltage: 1.8V (fixed)
• Output current: 500mA
• Input voltage maximum: 12V
• Dropout voltage: 0.37V @ 500mA
• Quiescent current: 110 µA
• Package: 8-MSOP
• Operating temperature range: -40°C ~ 85°C
• Control features: Shutdown
• Protection features: Over Current, Over Temperature
• Product status: Active
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

The primary difference between these parts is packaging format: the main part uses Tape & Reel (TR) format, while the substitute uses Cut Tape (CT) & Digi-Reel® format. Both formats contain identical die and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both ADP3335ARMZ-1.8-RL and ADP3335ARMZ-1.8-R7 maintain Active product status and are ROHS3 compliant with REACH Unaffected designation. Selection between these parts should be based on packaging format requirements and supply availability. The Tape & Reel format (ADP3335ARMZ-1.8-RL) is suitable for high-volume automated assembly operations. The Cut Tape & Digi-Reel® format (ADP3335ARMZ-1.8-R7) accommodates lower-volume production runs and mixed-component orders. Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ADP3335ARMZ-1.8-R7 be used as a direct replacement for ADP3335ARMZ-1.8-RL?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). PCB layout, schematic design, and performance characteristics remain unchanged.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel format supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape & Digi-Reel® format provides components on cut tape segments or alternative reel formats, suitable for lower-volume production and manual assembly operations. Electrical performance is identical.

Q: Are there any thermal or electrical performance differences between these substitutes?

A: No. Both parts deliver identical output voltage (1.8V), output current (500mA), dropout voltage (0.37V @ 500mA), quiescent current (110 µA), and operating temperature range (-40°C ~ 85°C).

Q: Do both parts support the same control and protection features?

A: Yes. Both ADP3335ARMZ-1.8-RL and ADP3335ARMZ-1.8-R7 include Shutdown control features and Over Current and Over Temperature protection.

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

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. These components can be stored indefinitely under standard conditions without requiring special moisture control or baking procedures prior to assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both ADP3335ARMZ-1.8-RL and ADP3335ARMZ-1.8-R7 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
