Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC1015IST6X is determined by the following critical parameters:

Package Compatibility: The original part uses a 6-TSOT (SOT-23-6 Thin) surface mount package. Substitute parts must use equivalent or identical package footprints to ensure PCB compatibility without redesign.

Electrical Specifications: Substitute parts must maintain rail-to-rail output capability and operate within the 2.5V to 5.5V supply voltage range. Single-circuit configuration is required to match the original topology.

Performance Envelope: The slew rate (145V/µs), gain bandwidth product (260 MHz), and output current capability (55 mA) establish the performance floor. Substitute parts may exceed these specifications without functional impact, provided they remain compatible with existing circuit designs.

Operating Temperature Range: The -40°C to 85°C operating range must be supported by substitute components.

Product Status: Active substitute parts are preferred to ensure long-term availability and supply chain continuity.

Two substitute parts meet these criteria: the LT1806IS6#TRPBF (Analog Devices Inc.) and the OPA355NA/250 (Texas Instruments).

Engineering Selection Recommendations

LT1806IS6#TRPBF Selection Criteria:

The LT1806IS6#TRPBF is an active product from Analog Devices Inc. with ROHS3 compliance and REACH unaffected status. This substitute maintains the identical 6-TSOT package footprint and operating temperature range (-40°C to 85°C). The slew rate of 140V/µs is functionally equivalent to the original 145V/µs specification. The gain bandwidth product of 325 MHz exceeds the original 260 MHz, providing enhanced frequency response. Supply voltage range extends to 12.6V maximum, offering greater flexibility in multi-supply applications. Input offset voltage is significantly improved at 0.1 mV versus 1.4 mV. Output current capability increases to 85 mA. Supply current consumption increases to 11 mA from 4.2 mA. MSL rating of 1 (Unlimited) matches the original specification. This substitute is suitable for applications where the increased supply current is acceptable and extended supply voltage range is beneficial.

OPA355NA/250 Selection Criteria:

The OPA355NA/250 is an active CMOS amplifier from Texas Instruments with ROHS3 compliance and REACH unaffected status. This substitute uses an identical SOT-23-6 package footprint. The slew rate of 360V/µs significantly exceeds the original specification, providing superior transient response. The -3dB bandwidth of 450 MHz is substantially higher than the original 90 MHz. Input bias current is exceptionally low at 3 pA (picoamperes) compared to 3 µA in the original. Input offset voltage is 2 mV, slightly higher than the original 1.4 mV. Output current capability is 100 mA, exceeding the original 55 mA. Supply voltage range is limited to 2.7V to 5.5V maximum, matching the original upper limit. Operating temperature extends to 125°C. Supply current is 8.3 mA. MSL rating is 2 (1 Year), requiring controlled storage conditions. This substitute is suitable for applications requiring low input bias current, high slew rate, and extended temperature operation.

Compliance and Availability:

Both substitute parts are active products with current manufacturing status, ensuring long-term supply chain continuity. Both comply with ROHS3 and REACH regulations. The LT1806IS6#TRPBF offers 19,081 pieces in stock inventory. The OPA355NA/250 offers 2,152 pieces in stock inventory. Selection between these substitutes depends on specific application requirements regarding supply current, supply voltage range, input bias current, and slew rate performance.

Frequently Asked Questions (FAQ)

Q: Why is the CLC1015IST6X classified as obsolete?

A: The CLC1015IST6X is no longer manufactured by MaxLinear, Inc. Obsolete status indicates the part has reached end-of-life and is not available for new production orders. Existing inventory may be available from authorized distributors, but long-term supply cannot be guaranteed.

Q: Can the LT1806IS6#TRPBF and OPA355NA/250 be used interchangeably with the CLC1015IST6X?

A: Both substitutes are pin-compatible and package-compatible with the original part. However, they differ in electrical performance characteristics. The LT1806IS6#TRPBF is more conservative in performance, while the OPA355NA/250 offers significantly enhanced specifications. Circuit validation is necessary to confirm compatibility with specific application requirements.

Q: What is the primary difference between the two substitute options?

A: The LT1806IS6#TRPBF is a general-purpose amplifier with moderate performance enhancements and extended supply voltage range (up to 12.6V). The OPA355NA/250 is a CMOS amplifier with superior slew rate (360V/µs), lower input bias current (3 pA), and higher bandwidth (450 MHz -3dB), but with limited supply voltage range (2.7V to 5.5V maximum) and MSL rating of 2 requiring controlled storage.

Q: Are both substitutes available in the same package as the original?

A: Yes. The LT1806IS6#TRPBF uses a 6-TSOT (SOT-23-6 Thin) package identical to the original. The OPA355NA/250 uses a SOT-23-6 package, which is mechanically and electrically compatible with the original 6-TSOT footprint. Both are surface mount devices suitable for automated assembly.

Q: What is the impact of increased supply current in the LT1806IS6#TRPBF?

A: The LT1806IS6#TRPBF draws 11 mA compared to 4.2 mA in the original. This 2.6× increase in supply current will increase power dissipation and heat generation. Applications with strict power budgets or thermal constraints may require thermal analysis to confirm acceptability.

Q: Why does the OPA355NA/250 have a lower MSL rating?

A: The OPA355NA/250 has an MSL rating of 2 (1 Year), compared to MSL 1 (Unlimited) for the original and LT1806IS6#TRPBF. MSL 2 requires that the component be stored in controlled humidity conditions and used within one year of the manufacturing date. This affects supply chain handling and shelf life management.

Q: Which substitute is recommended for low-power applications?

A: The LT1806IS6#TRPBF is not recommended for low-power applications due to its 11 mA supply current. The original CLC1015IST6X at 4.2 mA is more suitable. If substitution is necessary, the OPA355NA/250 at 8.3 mA is a compromise option, though still higher than the original.

Q: Which substitute is recommended for high-speed applications?

A: The OPA355NA/250 is recommended for high-speed applications, offering a slew rate of 360V/µs (2.5× the original) and -3dB bandwidth of 450 MHz (5× the original). The LT1806IS6#TRPBF with 140V/µs slew rate is functionally equivalent to the original 145V/µs.

Q: Can the CLC1015IST6X be used in new designs?

A: No. The CLC1015IST6X is obsolete and not available for new production orders. New designs must use active substitute parts. The LT1806IS6#TRPBF or OPA355NA/250 should be selected based on application requirements.

Q: What compliance certifications do the substitutes carry?

A: Both the LT1806IS6#TRPBF and OPA355NA/250 are ROHS3 compliant and REACH unaffected. These certifications ensure compliance with environmental and hazardous substance regulations in the European Union and other regulated markets.
