Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS3480CX50 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Output Configuration & Type: Positive fixed output voltage
• Voltage Specifications: 5V fixed output, 35V maximum input, 1.1V maximum dropout at 100mA
• Current Ratings: 100mA output current, 5mA quiescent current
• Package Compatibility: SOT-23-3 surface mount package (TO-236-3, SC-59 designations)
• Operating Temperature: -40°C to 125°C range
• Compliance: ROHS3 compliant, REACH unaffected status
• Manufacturer: Taiwan Semiconductor Corporation
• Product Status: Active production

The TS3480CX50 RFG variant meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the TS3480CX50 and TS3480CX50 RFG are active production parts from Taiwan Semiconductor Corporation with identical electrical specifications and package configurations. Selection between these parts is based on inventory availability and supply chain requirements rather than technical performance differences.

The TS3480CX50 RFG variant carries an additional Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating superior moisture handling characteristics during storage and handling. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can TS3480CX50 RFG be used as a direct replacement for TS3480CX50?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (5V), output current (100mA), input voltage range (35V maximum), dropout voltage (1.1V @ 100mA), quiescent current (5mA), operating temperature range (-40°C to 125°C), and SOT-23 package configuration. They are interchangeable in circuit design and PCB layout.

Q: What does the "RFG" suffix indicate?

A: The RFG designation identifies a specific manufacturing batch or variant from Taiwan Semiconductor Corporation. It does not indicate a functional or electrical difference from the base TS3480CX50 part number. The RFG variant includes an MSL rating of 1 (Unlimited).

Q: Are there package compatibility considerations between these parts?

A: No. Both parts use the identical SOT-23-3 surface mount package (also designated TO-236-3 or SC-59). PCB footprints, solder pad configurations, and mounting procedures are identical.

Q: What compliance certifications apply to both parts?

A: Both TS3480CX50 and TS3480CX50 RFG are ROHS3 compliant and REACH unaffected. They meet current environmental regulations for electronic component manufacturing and distribution.

Q: How should I select between these two part numbers?

A: Selection is based on inventory availability and supply chain logistics. The TS3480CX50 RFG offers higher inventory levels (26,079 units) compared to TS3480CX50 (16,400 units). The RFG variant also provides an MSL rating of 1 (Unlimited) for enhanced moisture protection during storage.
