Substitute Part Grouping Explanation

Substitute parts for the THS4500IDR are qualified based on electrical and mechanical parameter equivalence within the differential amplifier category. The substitution logic is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: Differential
• Number of Circuits: 1
• Output Type: Differential
• Slew Rate: 2800 V/µs
• Gain Bandwidth Product: 300 MHz
• -3dB Bandwidth: 370 MHz
• Current - Input Bias: 4 µA
• Voltage - Input Offset: 4 mV
• Current - Supply: 23 mA
• Voltage - Supply Span: 4.5 V to 15 V
• Operating Temperature Range: -40°C to 85°C

Mechanical Equivalence Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 8-SOIC

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts maintain identical electrical performance specifications and mechanical compatibility with the original THS4500IDR design. Packaging format differences (Tape & Reel versus Tube) do not affect electrical or mechanical substitution suitability.

Parameter Comparison

Engineering Selection Recommendations

THS4501IDR is the manufacturer-recommended primary substitute for the obsolete THS4500IDR. This part maintains complete electrical and mechanical equivalence while offering Active product status, ensuring long-term availability and supply chain continuity. The THS4501IDR is supplied in Tape & Reel packaging format, suitable for high-volume automated assembly operations. Current inventory of 4093 pieces supports immediate procurement requirements.

THS4500ID serves as an alternative substitute, providing identical electrical performance and mechanical compatibility. This part is supplied in Tube packaging format and maintains Active product status. The THS4500ID is appropriate for applications requiring tube-packaged components or lower-volume procurement scenarios. Current inventory of 1258 pieces is available.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The transition from the obsolete THS4500IDR to either active substitute part requires no circuit redesign or board layout modifications, as all electrical parameters and package dimensions remain identical.

Frequently Asked Questions (FAQ)

Q: Can THS4501IDR directly replace THS4500IDR in existing designs?

A: Yes. The THS4501IDR is electrically and mechanically identical to the THS4500IDR. All electrical parameters, including slew rate, gain-bandwidth product, input bias current, and supply voltage specifications, are equivalent. The 8-SOIC package dimensions and pinout are identical, enabling direct substitution without circuit or layout modifications.

Q: What is the difference between THS4501IDR and THS4500ID?

A: The primary difference is packaging format. THS4501IDR is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly. THS4500ID is supplied in Tube format, suitable for manual handling or lower-volume assembly processes. All electrical specifications and mechanical package dimensions are identical between these parts.

Q: Why is the THS4500IDR classified as Obsolete?

A: The THS4500IDR has reached end-of-life status. Texas Instruments recommends transitioning to the active THS4501IDR or THS4500ID for new designs and ongoing production support. Both substitute parts provide identical functionality with assured long-term availability.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All three parts—THS4500IDR, THS4501IDR, and THS4500ID—are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are equivalent across all parts.

Q: Which substitute should be selected for new production designs?

A: THS4501IDR is the manufacturer-recommended choice for new designs. It offers Active product status, higher current inventory availability (4093 pieces), and Tape & Reel packaging optimized for modern manufacturing processes. THS4500ID is an acceptable alternative if tube packaging is required or preferred.

Q: Is the -3dB Bandwidth specification identical across all three parts?

A: Yes. All three parts—THS4500IDR, THS4501IDR, and THS4500ID—specify -3dB Bandwidth of 370 MHz. This parameter is identical and does not vary between the main part and substitutes.

Q: Can THS4500ID be used in applications originally designed for THS4500IDR?

A: Yes. THS4500ID is electrically and mechanically equivalent to THS4500IDR. The only difference is packaging format (Tube versus the original Tape & Reel or Tube format). All electrical performance characteristics, operating parameters, and physical package dimensions are identical, enabling direct substitution.
