OP270GS Equivalent & Substitute Parts

Part Overview

The OP270GS is a general-purpose operational amplifier manufactured by Analog Devices Inc., configured as a dual-circuit (2-circuit) device in a 16-SOIC surface-mount package. This component is classified as obsolete, indicating discontinued production and limited availability through standard distribution channels. The OP270GS operates across a wide supply voltage range of 9V to 36V and maintains performance specifications across the industrial temperature range of -40°C to 85°C. Identification of equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this operational amplifier.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP270GS is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Performance Parameters: Slew rate (2.4 V/µs), gain bandwidth product (5 MHz), input bias current (15 nA), input offset voltage (50 µV), and supply current (4 mA) must be identical. The supply voltage range (9V to 36V minimum and maximum) must be matched exactly to ensure compatibility with existing power distribution designs.

Functional Configuration: The substitute must provide exactly two operational amplifier circuits (dual configuration) classified as general-purpose amplifiers.

Thermal and Environmental Specifications: Operating temperature range (-40°C to 85°C) must be maintained. Moisture sensitivity level (MSL 1 - Unlimited) must be equivalent or superior.

Mechanical and Packaging Requirements: The package type must be 16-SOIC with identical physical dimensions (0.295" width, 7.50mm width). Surface-mount mounting type is required.

Regulatory and Compliance Status: While product status may differ (obsolete versus active), regulatory classifications (ECCN, HTSUS) remain consistent across equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

The OP270GSZ serves as a direct functional equivalent to the OP270GS. All critical electrical parameters, thermal specifications, and mechanical package requirements are identical between the two parts. The primary distinction is product status: the OP270GS is classified as obsolete, while the OP270GSZ is active in production.

Selection of the OP270GSZ is supported by the following engineering considerations:

Regulatory Compliance: The OP270GSZ carries ROHS3 compliance certification and REACH unaffected status, providing enhanced environmental and regulatory alignment with current manufacturing standards. These certifications are not specified for the OP270GS.

Supply Chain Continuity: The OP270GSZ maintains active production status with documented inventory availability (2546 pieces), ensuring reliable procurement compared to the obsolete OP270GS (1850 pieces, limited availability).

Functional Interchangeability: Identical electrical performance across all specified parameters (slew rate, bandwidth, bias current, offset voltage, supply current, and temperature range) ensures direct substitution without circuit redesign or performance degradation.

Packaging Consideration: The OP270GSZ is supplied in tube packaging, which is standard for active production components. The original OP270GS packaging specification is not detailed in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the OP270GSZ be used as a direct replacement for the OP270GS in existing designs?
