AP130-33WL-7 Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The AP130-33WL-7 is a linear voltage regulator IC manufactured by Diodes Incorporated, designed to deliver a fixed 3.3V output at 300mA. This positive fixed output regulator operates across an input voltage range up to 5.5V with a maximum dropout voltage of 0.5V at full load current. The device integrates over-current, over-temperature, and short-circuit protection features, making it suitable for power management applications requiring stable 3.3V rails.

The AP130-33WL-7 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and support ongoing production requirements for systems utilizing this regulator topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP130-33WL-7 is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 3.3V fixed
• Output current capability: 300mA
• Input voltage maximum rating: 5.5V
• Dropout voltage performance: 0.5V @ 300mA
• Quiescent current: 100 µA
• Protection feature set: Over Current, Over Temperature, Short Circuit
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface Mount
• Base product family: AP130 series
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

All substitute parts listed maintain identical electrical performance specifications. Variations exist only in packaging configuration (SC-59-3 tape & reel versus SOT-23-3), product status (active versus obsolete), and moisture sensitivity level ratings. These packaging and MSL differences do not affect functional equivalence in circuit operation.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts—AP130-33WG-7, AP130-33RG-7, and AP130-33SAG-7—are functionally equivalent to the AP130-33WL-7 across all electrical performance parameters. Selection among these alternatives should be based on the following criteria:

Product Status: AP130-33WG-7, AP130-33RG-7, and AP130-33SAG-7 all carry active product status, ensuring ongoing manufacturer support and availability. The original AP130-33WL-7 is obsolete and should be replaced in new designs.

Packaging and Supply Format: AP130-33WG-7 and AP130-33RG-7 are supplied in tape & reel format, suitable for automated assembly processes. AP130-33SAG-7 is also supplied in tape & reel format. The original AP130-33WL-7 was supplied in tube format. Selection depends on production volume and assembly equipment compatibility.

Package Variant: AP130-33RG-7 uses SC-59R package variant, while AP130-33WG-7 and AP130-33SAG-7 use standard SC-59-3 and SOT-23-3 packages respectively. All three packages are mechanically and electrically compatible within the TO-236-3 family footprint.

Moisture Sensitivity Level: AP130-33WG-7 and AP130-33RG-7 carry MSL-3 (168 Hours) rating, while AP130-33SAG-7 carries MSL-1 (Unlimited) rating, matching the original part. MSL-1 rated devices are preferred for applications with extended storage or high-humidity environments.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can AP130-33WG-7, AP130-33RG-7, and AP130-33SAG-7 be used interchangeably with AP130-33WL-7 in existing designs?

A: Yes. All three substitute parts deliver identical electrical performance: 3.3V fixed output, 300mA output current, 0.5V maximum dropout voltage, and equivalent protection features. Electrical substitution is direct. Physical substitution requires verification of PCB footprint compatibility with the specific package variant selected.

Q: What is the difference between SC-59-3, SC-59R, and SOT-23-3 packages?

A: All three packages belong to the TO-236-3 family and share the same pin configuration and electrical characteristics. SC-59-3 is the standard variant, SC-59R is a tape & reel optimized variant, and SOT-23-3 is an alternative designation for the same package family. PCB footprints are compatible across all three variants.

Q: Why does the original AP130-33WL-7 have MSL-1 rating while AP130-33WG-7 and AP130-33RG-7 have MSL-3?

A: MSL (Moisture Sensitivity Level) ratings reflect component sensitivity to moisture absorption during storage and handling. MSL-1 (Unlimited) indicates no moisture sensitivity restrictions, while MSL-3 (168 Hours) requires controlled storage conditions. For applications with extended storage or high-humidity environments, AP130-33SAG-7 (MSL-1) is preferred. For standard manufacturing environments with proper moisture control, MSL-3 parts are acceptable.

Q: Which substitute part should be selected for new production designs?

A: AP130-33WG-7 or AP130-33SAG-7 are recommended for new designs. Both carry active product status ensuring long-term availability. AP130-33SAG-7 is preferred if MSL-1 rating is required; AP130-33WG-7 is preferred for high-volume automated assembly with tape & reel supply.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. AP130-33WG-7, AP130-33RG-7, and AP130-33SAG-7 all carry ROHS3 compliance certification, matching the original AP130-33WL-7 specification.
