Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL1453CPWRG4 is determined by strict equivalence across the following critical parameters:

• Identical PWM output type and boost topology configuration
• Matching dual-output, single-phase architecture
• Equivalent supply voltage range (3.6V ~ 40V)
• Identical switching frequency capability (1kHz ~ 500kHz)
• Same control feature set (Dead Time Control, Frequency Control)
• Matching operating temperature range (-20°C ~ 85°C)
• Identical 16-TSSOP package footprint and pinout
• Equivalent regulatory compliance (ROHS3, REACH Unaffected)

The TL1453CPWR substitute meets all these criteria and represents the direct equivalent with identical electrical and mechanical specifications. The primary difference is packaging format (Tape & Reel versus individual packaging) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The TL1453CPWR is the direct functional and electrical equivalent of the TL1453CPWRG4. Both parts share identical specifications across all critical parameters including topology, output configuration, voltage range, switching frequency, control features, and thermal operating range. The substitute maintains full ROHS3 compliance and REACH Unaffected status, ensuring regulatory continuity.

The primary distinction is product lifecycle status: the TL1453CPWRG4 is discontinued, while the TL1453CPWR maintains active status with significantly higher inventory availability (91,100 pieces versus 1,945 pieces). For new designs or ongoing production requiring boost regulator controller functionality with the specified electrical characteristics, the TL1453CPWR is the appropriate selection. The Tape & Reel packaging format of the substitute is standard for production-volume applications and offers cost efficiency for manufacturing operations.

Frequently Asked Questions (FAQ)
