CLC1002ISO8X Equivalent & Substitute Parts Reference

Part Overview

The CLC1002ISO8X is a voltage feedback amplifier integrated circuit manufactured by MaxLinear, Inc., housed in an 8-SOIC surface mount package. This single-circuit amplifier is designed for high-speed signal conditioning applications requiring a gain bandwidth product of 965 MHz and slew rate of 170V/µs. The device operates across a 4V to 12V supply range with an operating temperature range of -40°C to 85°C.

The CLC1002ISO8X has reached obsolete product status. Locating equivalent substitute parts is necessary to support ongoing production requirements, field repairs, and system redesigns where this amplifier is currently specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC1002ISO8X is determined by the following mandatory compatibility criteria:

Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Functional Classification: All substitute parts must be single-circuit voltage feedback amplifiers, maintaining the same functional topology and circuit count.

Supply Voltage Range: Substitute parts must operate within the original supply voltage specification. The CLC1002ISO8X operates from 4V to 12V. Substitute parts with minimum supply voltage requirements of 5V or 6V remain compatible with systems designed for the 4V to 12V range, provided the actual operating voltage meets the substitute part's minimum requirement.

Operating Temperature Range: All substitute parts must support the -40°C to 85°C operating temperature range to maintain thermal compatibility in the target application environment.

Electrical Performance Envelope: Substitute parts must meet or exceed the original performance specifications for slew rate, gain bandwidth product, and output current capability to ensure functional equivalence or improvement in signal fidelity and drive capability.

The three substitute parts listed—AD8037ARZ, OPA847ID, and OPA847IDR—satisfy all mandatory compatibility criteria and are classified as direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

AD8037ARZ (Analog Devices Inc.): This substitute part is classified as active product status with ROHS3 compliance. The AD8037ARZ demonstrates superior slew rate performance at 1500V/µs compared to the original 170V/µs specification, providing enhanced transient response capability. Input bias current is reduced to 3µA, improving input impedance characteristics. The -3dB bandwidth of 270MHz closely matches the original 290MHz specification. Minimum supply voltage requirement is 6V, which is compatible with systems operating above this threshold. Moisture sensitivity level remains at MSL 1 (Unlimited), matching the original specification.

OPA847ID (Texas Instruments): This substitute part is classified as active product status with ROHS3 compliance. The OPA847ID provides a gain bandwidth product of 3.9GHz, substantially exceeding the original 965MHz specification. Slew rate of 950V/µs significantly improves transient performance. Input offset voltage is reduced to 100µV from the original 500µV, enhancing DC accuracy. Output current capability of 100mA is lower than the original 130mA specification. Minimum supply voltage is 5V. Moisture sensitivity level is MSL 2 (1 Year), requiring controlled storage conditions.

OPA847IDR (Texas Instruments): This substitute part is identical in electrical specifications to OPA847ID, classified as active product status with ROHS3 compliance. The primary distinction is packaging designation. Both OPA847ID and OPA847IDR share the same electrical performance envelope, supply voltage requirements, and moisture sensitivity level of MSL 2 (1 Year).

All three substitute parts maintain the 8-SOIC surface mount package format and -40°C to 85°C operating temperature range, ensuring direct compatibility with existing PCB designs and thermal operating environments.

Frequently Asked Questions (FAQ)

Q: Can the AD8037ARZ be used as a direct replacement for the CLC1002ISO8X without PCB modifications?

A: Yes. Both devices use the 8-SOIC surface mount package with identical 0.154" (3.90mm) width. Pin-to-pin compatibility is maintained. However, the minimum supply voltage for AD8037ARZ is 6V, whereas the CLC1002ISO8X operates from 4V. Verify that your system supply voltage meets or exceeds 6V before substitution.

Q: What is the difference between OPA847ID and OPA847IDR?

A: Both parts are manufactured by Texas Instruments and share identical electrical specifications, performance characteristics, and operating parameters. The designation difference reflects packaging or distribution channel variations. Both are functionally equivalent for circuit design purposes.

Q: Does the higher slew rate of substitute parts affect circuit stability?

A: Slew rate is a performance specification that indicates the maximum rate of voltage change the amplifier can produce. Higher slew rate values (such as 950V/µs or 1500V/µs compared to 170V/µs) represent improved capability and do not introduce instability. Circuit stability is determined by feedback network design and compensation, which remain unchanged when substituting parts with identical package and pin configuration.

Q: Are there supply voltage compatibility concerns when substituting these parts?

A: The CLC1002ISO8X operates from 4V minimum. The AD8037ARZ requires 6V minimum, and both OPA847 variants require 5V minimum. If your system operates at 4V to 5V, only the OPA847ID or OPA847IDR are compatible. If your system operates at 6V or higher, all three substitutes are compatible. Verify your actual operating supply voltage before selection.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and can be stored indefinitely without special handling. MSL 2 (1 Year) requires controlled storage conditions and limits shelf life to one year from the date of manufacture. The OPA847ID and OPA847IDR require more stringent moisture control during storage and handling compared to the CLC1002ISO8X and AD8037ARZ.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. The CLC1002ISO8X is RoHS Compliant. All three substitute parts are ROHS3 Compliant, which represents an updated RoHS standard. ROHS3 compliance is compatible with RoHS requirements and indicates no restricted substances are present.

Q: Which substitute part provides the best overall performance improvement?

A: Selection depends on application requirements. The OPA847ID and OPA847IDR offer the highest gain bandwidth product (3.9GHz) and superior slew rate (950V/µs), making them suitable for high-frequency signal conditioning. The AD8037ARZ provides the highest slew rate (1500V/µs) with lower input bias current (3µA), suitable for precision applications requiring fast transient response. All three exceed the original performance envelope in at least one critical parameter.
