Parameter Comparison

Engineering Selection Recommendations

The THS4130IDR is the direct manufacturer-recommended substitute for the THS4130CD. Both devices share identical functional specifications across all critical amplifier parameters, including slew rate, gain bandwidth product, bandwidth, input bias current, input offset voltage, and output current capability. Both components are packaged in the same 8-SOIC form factor with identical pin configurations and mounting requirements.

The THS4130IDR offers the following advantages over the THS4130CD:

Supply Voltage Span: The THS4130IDR supports a minimum supply voltage of 4 V compared to 5 V for the THS4130CD, and a maximum of 33 V compared to 30 V. This extended range provides greater design flexibility for applications with variable supply conditions.

Supply Current: The THS4130IDR operates at 12.3 mA compared to 14 mA for the THS4130CD, resulting in lower power consumption.

Operating Temperature Range: The THS4130IDR operates across -40°C to 85°C, compared to 0°C to 70°C for the THS4130CD. This extended temperature range accommodates industrial and automotive applications requiring broader environmental specifications.

Product Status: The THS4130IDR maintains Active status with 6642 units in stock, ensuring long-term availability and supply chain continuity. The THS4130CD is designated Last Time Buy, indicating production discontinuation.

Both devices maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the THS4130IDR be used as a direct replacement for the THS4130CD in existing designs?

A: Yes. The THS4130IDR is a direct substitute for the THS4130CD. Both devices share identical functional specifications, package type, and pin configuration. The THS4130IDR can be substituted without circuit modifications. The extended operating temperature range and improved supply voltage span of the THS4130IDR provide additional design margin.

Q: What are the key differences between the THS4130CD and THS4130IDR?

A: The primary differences are product status, operating temperature range, supply voltage span, and supply current. The THS4130IDR is Active with extended temperature range (-40°C to 85°C versus 0°C to 70°C), wider supply voltage span (4 V to 33 V versus 5 V to 30 V), and lower supply current (12.3 mA versus 14 mA). All amplifier performance parameters are identical.

Q: Are both parts packaged identically?

A: Yes. Both the THS4130CD and THS4130IDR are packaged in 8-SOIC (0.154", 3.90mm Width) surface mount packages with identical pin configurations and footprints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the THS4130CD and THS4130IDR are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, REACH unaffected status, and EAR99 ECCN classification.

Q: Why is the THS4130CD designated as Last Time Buy?

A: Last Time Buy designation indicates that the manufacturer has discontinued or will discontinue production of this part number. The THS4130IDR is the active equivalent and recommended substitute for new designs and ongoing production requirements.

Q: What is the impact of the lower minimum supply voltage (4 V) of the THS4130IDR compared to the THS4130CD (5 V)?

A: The lower minimum supply voltage of the THS4130IDR expands design flexibility by allowing operation in applications with lower supply rails. This does not affect compatibility with designs currently operating at 5 V or higher.

Q: Does the extended operating temperature range of the THS4130IDR affect its use in standard commercial applications?

A: No. The extended operating temperature range of the THS4130IDR (-40°C to 85°C) is a superset of the THS4130CD range (0°C to 70°C). The THS4130IDR operates reliably across all conditions where the THS4130CD operates, plus additional temperature extremes.

Q: Are there any inventory considerations when transitioning from THS4130CD to THS4130IDR?

A: The THS4130IDR has 6642 units in stock with Active product status, ensuring reliable long-term availability. The THS4130CD has 2100 units in stock with Last Time Buy status, indicating limited future availability.
