TPS60121PWPR Equivalent & Substitute Parts

Part Overview

The TPS60121PWPR is a charge pump switching regulator IC from Texas Instruments designed for step-up voltage conversion. It delivers a fixed 3.3V output at 200mA from input voltages ranging from 1.8V to 3.6V, utilizing a 320kHz switching frequency topology. The device is packaged in a 20-PowerTSSOP surface mount package.

The TPS60121PWPR has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this charge pump regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS60121PWPR is determined by strict alignment across the following critical parameters:

• Topology & Function: Charge pump step-up regulator with positive output configuration
• Output Specification: Fixed 3.3V output at 200mA
• Input Voltage Range: 1.8V to 3.6V
• Package Compatibility: 20-PowerTSSOP (0.173", 4.40mm Width) / 20-HTSSOP
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected
• Mounting Type: Surface Mount

The TPS60100PWPR meets all substitution criteria. Both devices share identical electrical specifications for input/output voltage, output current, and package form factor. The primary distinction is product status: TPS60121PWPR is obsolete, while TPS60100PWPR maintains active status with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The TPS60100PWPR is the direct substitute for the obsolete TPS60121PWPR. Both devices are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters: input voltage range (1.8V–3.6V), fixed 3.3V output, 200mA output current, charge pump topology, and 20-PowerTSSOP package form factor.

The switching frequency difference (320kHz vs. 300kHz) is within acceptable operational variance for charge pump regulators and does not affect functional compatibility in applications designed for the TPS60121PWPR.

The TPS60100PWPR maintains active product status with current manufacturing availability and documented operating temperature range (-40°C to 85°C), providing superior supply chain reliability compared to the obsolete TPS60121PWPR. Both devices meet ROHS3 compliance and REACH unaffected regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the TPS60100PWPR directly replace the TPS60121PWPR in existing designs?

A: Yes. The TPS60100PWPR is a direct substitute. Both devices share identical input/output voltage specifications, output current rating, package form factor (20-PowerTSSOP), and regulatory compliance status. Pin-to-pin compatibility and functional equivalence are confirmed.

Q: What is the significance of the switching frequency difference (320kHz vs. 300kHz)?

A: The 20kHz difference in switching frequency is within normal operational tolerance for charge pump regulators. This variance does not affect output voltage regulation, current delivery capability, or circuit compatibility. Both frequencies operate within the same efficiency envelope for this device class.

Q: Why is the TPS60121PWPR listed as obsolete?

A: Product obsolescence reflects Texas Instruments' manufacturing and support decisions. The TPS60100PWPR represents the active continuation of this charge pump regulator line, offering equivalent performance with ongoing availability and technical support.

Q: Are there any thermal or operating condition differences between these parts?

A: The TPS60100PWPR specifies an operating temperature range of -40°C to 85°C. The TPS60121PWPR does not include published operating temperature specifications in the provided data. For applications requiring defined thermal performance, the TPS60100PWPR provides documented operating parameters.

Q: What packaging options are available for the TPS60100PWPR?

A: The TPS60100PWPR is supplied in Tape & Reel (TR) packaging in the 20-HTSSOP configuration, matching the package specification of the TPS60121PWPR. This ensures compatibility with automated assembly processes and existing board designs.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the TPS60121PWPR and TPS60100PWPR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
