THS4304DR Equivalent & Substitute Parts

Part Overview

The THS4304DR is a voltage feedback amplifier integrated circuit manufactured by Texas Instruments, designed for high-speed signal conditioning applications. This device features a single amplifier circuit in an 8-SOIC surface mount package with a gain bandwidth product of 870 MHz and slew rate of 830 V/µs.

The THS4304DR is classified as an obsolete product. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when design flexibility is required for procurement optimization. The THS4304D serves as the manufacturer-recommended substitute, offering identical electrical performance with active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the THS4304DR with the THS4304D is based on strict electrical and mechanical parameter equivalence. Both devices share identical specifications across all critical performance parameters that define functional compatibility:

Electrical Parameter Equivalence:

• Amplifier topology: Voltage Feedback (identical)
• Circuit count: 1 (identical)
• Slew rate: 830 V/µs (identical)
• Gain bandwidth product: 870 MHz (identical)
• -3dB bandwidth: 3 GHz (identical)
• Input bias current: 7 µA (identical)
• Input offset voltage: 500 µV (identical)
• Supply current: 18 mA (identical)
• Supply voltage range: 2.7 V to 5 V (identical)
• Operating temperature: -40°C to 85°C (identical)

Mechanical Parameter Equivalence:

• Package type: 8-SOIC (identical)
• Package dimensions: 0.154" × 3.90mm width (identical)
• Mounting type: Surface Mount (identical)

Compliance Equivalence:

• RoHS3 Compliant (both)
• Moisture Sensitivity Level 1 (both)
• REACH Unaffected (both)

The primary distinction is product status: THS4304DR is obsolete, while THS4304D is active. The packaging format differs (THS4304D supplied in Tube), but this does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The THS4304D is the direct substitute for the THS4304DR based on complete electrical and mechanical parameter equivalence. Selection criteria are as follows:

For Obsolete Component Replacement: The THS4304DR is classified as obsolete. The THS4304D maintains identical electrical specifications and mechanical compatibility, making it suitable for direct replacement in existing designs without circuit modification.

For New Design Implementation: The THS4304D is the recommended choice due to active product status, ensuring long-term availability and supply chain stability. Both devices are ROHS3 compliant and carry identical environmental certifications (REACH Unaffected, MSL 1).

Compliance Considerations: Both parts meet the same regulatory requirements. No additional compliance verification is required when substituting THS4304DR with THS4304D in applications subject to RoHS or REACH regulations.

Packaging and Procurement: The THS4304D is supplied in Tube packaging, whereas the THS4304DR packaging format is not specified. This difference does not affect electrical performance or mechanical fit on printed circuit boards.

Frequently Asked Questions (FAQ)

Q: Can THS4304D be used as a direct replacement for THS4304DR in existing circuit designs?

A: Yes. The THS4304D is electrically and mechanically identical to the THS4304DR. All electrical parameters, including slew rate, gain bandwidth product, input bias current, and supply voltage range, are identical. The 8-SOIC package dimensions are identical, allowing direct PCB footprint compatibility without design modification.

Q: What is the primary reason to substitute THS4304DR with THS4304D?

A: The THS4304DR is classified as obsolete, while the THS4304D is active. Substitution is necessary to ensure component availability and supply chain continuity. The THS4304D provides identical performance with improved procurement reliability.

Q: Are there any differences in compliance or environmental certifications between these parts?

A: No. Both the THS4304DR and THS4304D are ROHS3 compliant, carry Moisture Sensitivity Level 1 (Unlimited), and are REACH Unaffected. No additional compliance verification is required when substituting between these parts.

Q: Does the packaging format difference affect compatibility?

A: No. The packaging format (Tube for THS4304D) refers to the shipping and storage container, not the component package itself. Both devices use the 8-SOIC surface mount package with identical dimensions (0.154" × 3.90mm width). PCB assembly compatibility is unaffected.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is based on equivalence across the following parameters: amplifier type (Voltage Feedback), circuit count (1), slew rate (830 V/µs), gain bandwidth product (870 MHz), -3dB bandwidth (3 GHz), input bias current (7 µA), input offset voltage (500 µV), supply current (18 mA), and supply voltage range (2.7 V to 5 V). All parameters are identical between THS4304DR and THS4304D.

Q: Is the THS4304D suitable for new design implementations?

A: Yes. The THS4304D is the recommended choice for new designs due to its active product status, ensuring long-term availability and supply chain stability. It provides identical electrical performance to the obsolete THS4304DR.
