TPS65012RGZRG4 Equivalent & Substitute Parts

Part Overview

The TPS65012RGZRG4 is a Battery Multi-Function Controller IC for Lithium Ion/Polymer single-cell applications, manufactured by Texas Instruments in a 48-VQFN (7x7) package with exposed pad. This part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and production continuity. The device integrates I2C and USB interfaces for battery management and monitoring functions across the -40°C to 85°C operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS65012RGZRG4 is determined by strict alignment across the following critical parameters:

• Battery Chemistry & Cell Count: All substitutes must support Lithium Ion/Polymer single-cell applications
• Interface Specification: I2C and USB interface support required
• Operating Temperature Range: -40°C to 85°C (TA) compliance mandatory
• Package & Mounting: 48-VFQFN Exposed Pad, Surface Mount configuration
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, MSL 2 (1 Year)

The four substitute parts listed below meet all these criteria and are manufactured by Texas Instruments. Differences exist only in base product number (TPS65011, TPS65012, TPS65013 variants) and packaging format (Tape & Reel vs. Bulk).

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products from Texas Instruments and maintain full compliance with ROHS3 and REACH requirements. Selection should prioritize active product status over the discontinued TPS65012RGZRG4.

TPS65012RGZR and TPS65012RGZT are direct variants of the original part number (TPS65012 base product) with identical functional specifications. Both are currently active and available in volume. The difference between these two is packaging format: RGZR indicates Tape & Reel packaging, while RGZT also indicates Tape & Reel with different reel specifications.

TPS65011RGZR represents an alternative base product (TPS65011) within the same controller family, maintaining all critical electrical and mechanical parameters. This part is active and available with 3200 units in stock.

TPS65013RGZT represents another alternative base product (TPS65013) with identical functional specifications and compliance certifications. This part is active with 2492 units in stock.

For new designs or production continuity, TPS65012RGZR or TPS65012RGZT are preferred due to base product alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TPS65011RGZR or TPS65013RGZT be used as direct replacements for TPS65012RGZRG4?

A: Yes. All substitute parts share identical battery chemistry (Lithium Ion/Polymer), cell count (1), interface specification (I2C, USB), operating temperature range (-40°C to 85°C), package configuration (48-VFQFN Exposed Pad), and regulatory compliance (ROHS3, REACH). Functional compatibility is established across all parameters provided in the specification.

Q: What is the difference between TPS65012RGZR and TPS65012RGZT?

A: Both are active variants of the TPS65012 base product with identical electrical and mechanical specifications. The difference is in packaging format designation (RGZR vs. RGZT), which relates to reel configuration for automated assembly. Functional performance and pin configuration are identical.

Q: Why is the original TPS65012RGZRG4 discontinued?

A: Product discontinuation at the distributor level does not indicate functional obsolescence. The substitute parts listed represent active alternatives from the same manufacturer with equivalent specifications. TPS65012RGZR and TPS65012RGZT maintain the same base product number and are currently in production.

Q: Are all substitutes ROHS3 and REACH compliant?

A: Yes. All four substitute parts are ROHS3 Compliant and REACH Unaffected, matching the compliance profile of the original TPS65012RGZRG4.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including substitutes, have MSL 2 (1 Year), indicating standard moisture sensitivity with a one-year floor life under controlled storage conditions.
