THS4151IDGNG4 Equivalent & Substitute Parts

Part Overview

The THS4151IDGNG4 is a differential amplifier integrated circuit manufactured by Texas Instruments, designed for high-speed signal conditioning applications. This device features a single differential amplifier circuit in an 8-HVSSOP surface mount package with an exposed pad for enhanced thermal performance.

The THS4151IDGNG4 is classified as obsolete. Locating active production alternatives is necessary for new designs, ongoing production support, and long-term component availability assurance. Substitute parts must maintain electrical performance and mechanical compatibility while offering active product status and improved supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

THS4151IDGN is the manufacturer-recommended substitute for the obsolete THS4151IDGNG4. This part maintains identical electrical specifications and mechanical packaging while offering active product status. The THS4151IDGN is supplied in tube packaging and demonstrates superior inventory availability (3200 units in stock). This part is suitable for direct replacement in new designs and production continuity applications.

THS4150IDGN is a parametric equivalent substitute. All electrical performance characteristics, mechanical dimensions, and compliance certifications are identical to the main part. The THS4150IDGN differs only in base product number designation (THS4150 versus THS4151) while maintaining the same functional performance envelope. This part is also supplied in tube packaging with active product status and adequate inventory availability (1116 units in stock).

Both substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity rating), ensuring compatibility with standard manufacturing and storage environments. Selection between THS4151IDGN and THS4150IDGN should be based on design requirements and supply chain considerations, as both parts deliver equivalent performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can THS4151IDGN directly replace THS4151IDGNG4 in existing designs?

A: Yes. The THS4151IDGN is the manufacturer-recommended substitute. All electrical parameters, mechanical package dimensions, and compliance certifications are identical. The primary difference is product status (active versus obsolete) and packaging format (tube versus the original format).

Q: What is the difference between THS4151IDGN and THS4150IDGN?

A: Both parts are parametric equivalents with identical electrical specifications and mechanical packaging. The difference is the base product number designation (THS4151 versus THS4150). Both deliver 650 V/µs slew rate, 340 MHz gain bandwidth product, and operate across the same -40°C to 85°C temperature range. Selection depends on design requirements and supply availability.

Q: Are the substitute parts compatible with the original PCB layout?

A: Yes. Both THS4151IDGN and THS4150IDGN use the same 8-HVSSOP package with 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) exposed pad configuration. Pin assignments and thermal pad dimensions are identical, ensuring direct PCB compatibility without layout modifications.

Q: What is the significance of the obsolete status for THS4151IDGNG4?

A: Obsolete status indicates the part is no longer in active production. Using active substitutes (THS4151IDGN or THS4150IDGN) ensures long-term supply chain reliability, access to current manufacturing processes, and compliance with current industry standards.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both THS4151IDGN and THS4150IDGN are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited) moisture sensitivity rating, matching the original part's compliance profile.

Q: What are the key electrical parameters that define substitutability?

A: The critical parameters are slew rate (650 V/µs), gain bandwidth product (340 MHz), -3dB bandwidth (150 MHz), input bias current (4.3 µA), input offset voltage (1.1 mV), supply current (17.5 mA), output current per channel (85 mA), and supply voltage range (4 V to 33 V). All substitutes maintain these specifications.

Q: Is there a performance difference between tube and the original packaging format?

A: No. Packaging format (tube versus original) does not affect electrical performance or functional characteristics. The difference is in component handling, storage, and supply chain logistics.
