CLC1008IST5X Equivalent & Substitute Parts

Part Overview

The CLC1008IST5X is a general purpose operational amplifier manufactured by MaxLinear, Inc., housed in a SOT-23-5 surface mount package. This device features rail-to-rail output capability and is designed for single-circuit amplification applications. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support, production continuity, and system maintenance. Equivalent parts must maintain functional compatibility across key electrical parameters including supply voltage range, output type, and thermal operating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC1008IST5X is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Mounting Type: Surface Mount
• Package / Case: SOT-23-5 compatible footprint
• Operating Temperature Range: -40°C to 85°C minimum
• Moisture Sensitivity Level: 1 (Unlimited)

Electrical Parameter Alignment: Substitute parts must operate within the supply voltage range of 2.5 V to 5.5 V. The slew rate (50 V/µs), gain bandwidth product (33 MHz), and output current capability (15 mA per channel) establish the performance envelope for signal conditioning applications. Input bias current (1.2 µA) and input offset voltage (1 mV) define the precision characteristics required for the substitution.

Two substitute parts meet these criteria with documented compatibility:

MP5121DJ-LF-Z (Monolithic Power Systems Inc.) — Active product status with extended supply voltage range (3.2 V to 20 V), enhanced output current capability (70 mA), and improved input bias current (500 nA). Package: TSOT-23-5.

OPA336N/3K (Texas Instruments) — Active product status with matched supply voltage range (2.3 V to 5.5 V), identical package specification (SOT-23-5), and superior input bias current (1 pA). Series designation: MicroAmplifier™.

Parameter Comparison

Engineering Selection Recommendations

OPA336N/3K (Texas Instruments) is the primary substitute for CLC1008IST5X applications. This part maintains identical package specification (SOT-23-5), matching supply voltage range (2.3 V to 5.5 V), and identical operating temperature range (-40°C to 85°C). The OPA336N/3K is an active product with full RoHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment. The device exhibits superior input bias current (1 pA) and input offset voltage (60 µV), providing enhanced precision characteristics. Current inventory of 8,268 pieces supports immediate procurement.

MP5121DJ-LF-Z (Monolithic Power Systems Inc.) serves as an alternative substitute where extended supply voltage capability (3.2 V to 20 V) and higher output current (70 mA) are advantageous. This part is also active with RoHS3 compliance and REACH unaffected status. The TSOT-23-5 package is mechanically compatible with SOT-23-5 footprints in most applications. Current inventory of 865 pieces is available.

Both substitutes are active products with current manufacturing support, regulatory compliance documentation, and established supply chains. Selection between OPA336N/3K and MP5121DJ-LF-Z depends on specific circuit requirements regarding supply voltage range and output current demands.

Frequently Asked Questions (FAQ)

Q: Can OPA336N/3K directly replace CLC1008IST5X in existing PCB designs?

A: Yes. Both devices use identical SOT-23-5 package specifications (SC-74A, SOT-753), enabling direct footprint compatibility. Pin configuration and functional operation are compatible for general purpose amplifier applications. No PCB layout modifications are required.

Q: What are the key differences between OPA336N/3K and MP5121DJ-LF-Z?

A: OPA336N/3K maintains the original supply voltage range (2.3 V to 5.5 V) and uses standard SOT-23-5 packaging. MP5121DJ-LF-Z extends the maximum supply voltage to 20 V and provides higher output current (70 mA versus 5 mA). MP5121DJ-LF-Z uses TSOT-23-5 (thin variant) packaging, which is mechanically compatible but represents a package variant.

Q: Is the TSOT-23-5 package compatible with SOT-23-5 PCB footprints?

A: TSOT-23-5 is a thin variant of SOT-23-5 with identical pin pitch and footprint dimensions. The reduced package height does not affect electrical or mechanical compatibility with standard SOT-23-5 land patterns.

Q: Why is CLC1008IST5X classified as obsolete?

A: The CLC1008IST5X is no longer manufactured by MaxLinear, Inc. Substitute parts from active manufacturers (Texas Instruments and Monolithic Power Systems Inc.) provide equivalent functionality with current production support and regulatory compliance.

Q: What compliance certifications apply to the substitute parts?

A: Both OPA336N/3K and MP5121DJ-LF-Z carry RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic components in industrial and commercial applications.

Q: How do the slew rate and bandwidth specifications compare?

A: CLC1008IST5X specifies 50 V/µs slew rate and 33 MHz gain bandwidth product. OPA336N/3K provides 0.03 V/µs slew rate and 100 kHz bandwidth, suitable for precision, low-frequency applications. MP5121DJ-LF-Z provides 45 V/µs slew rate and 14 MHz bandwidth, maintaining moderate-speed performance. Application requirements determine which substitute is appropriate.

Q: What is the input bias current difference between the main part and substitutes?

A: CLC1008IST5X specifies 1.2 µA input bias current. OPA336N/3K provides 1 pA (significantly lower), while MP5121DJ-LF-Z provides 500 nA. Lower input bias current reduces loading effects on signal sources and improves precision in high-impedance circuits.

Q: Are there inventory considerations for component selection?

A: OPA336N/3K has 8,268 pieces in stock, providing substantial availability. MP5121DJ-LF-Z has 865 pieces available. Both quantities support production requirements, though OPA336N/3K offers greater immediate availability.
