Substitute Part Grouping Explanation
Substitution eligibility for the OP90GSZ-REEL is determined by the following criteria:
Package Compatibility: All substitute parts must use 8-SOIC (0.154", 3.90mm Width) surface mount package configuration to ensure mechanical and electrical compatibility with existing PCB layouts.
Amplifier Classification: All parts must be classified as general-purpose operational amplifiers with single-circuit configuration.
Supply Voltage Range: Substitute parts must operate within or encompass the OP90GSZ-REEL supply voltage range of 1.6V to 36V. Parts with narrower ranges may be substituted only when the application operates entirely within the substitute part's specified range.
Operating Temperature Range: The OP90GSZ-REEL operates from -40°C to 85°C. Substitute parts with equivalent or extended temperature ranges are acceptable.
Compliance Status: All substitute parts must maintain ROHS3 compliance and equivalent moisture sensitivity classification (MSL 1).
The following parts meet these substitution criteria: MC33171DT, OPA637AU/2K5, HA9P5127-5Z, and MC33071DR2G.

Engineering Selection Recommendations
MC33171DT (STMicroelectronics): This substitute maintains ROHS3 compliance and MSL 1 classification. Operating temperature range extends to 105°C, exceeding the OP90GSZ-REEL specification. Supply voltage range spans 4V to 44V, encompassing the upper range of the OP90GSZ-REEL but requiring minimum 4V operation. All parts are Active status.
MC33071DR2G (onsemi): This substitute maintains ROHS3 compliance and MSL 1 classification. Operating temperature range matches the OP90GSZ-REEL at -40°C to 85°C. Supply voltage range spans 3V to 44V, providing broader compatibility. All parts are Active status.
HA9P5127-5Z (Renesas Electronics Corporation): This substitute maintains ROHS3 compliance and MSL 1 classification. Operating temperature range is 0°C to 75°C, which is narrower than the OP90GSZ-REEL. Supply voltage range spans 10V to 30V, which is narrower than the OP90GSZ-REEL. Substitution is valid only when applications operate within 0°C to 75°C and 10V to 30V parameters. All parts are Active status.
OPA637AU/2K5 (Texas Instruments): This substitute maintains ROHS3 compliance but has MSL 3 classification (168 Hours), differing from the OP90GSZ-REEL MSL 1. Operating temperature range is -25°C to 85°C, narrower at the lower end. Supply voltage range spans 9V to 36V, requiring minimum 9V operation. All parts are Active status.
Frequently Asked Questions (FAQ)
Q: Can MC33171DT replace OP90GSZ-REEL in all applications?
A: MC33171DT is mechanically and electrically compatible in applications where the minimum supply voltage requirement of 4V is met. The OP90GSZ-REEL operates at 1.6V minimum, so applications requiring sub-4V operation cannot use MC33171DT as a substitute.
Q: What is the primary difference between MC33071DR2G and OP90GSZ-REEL?
A: Both parts share identical 8-SOIC packaging, ROHS3 compliance, and MSL 1 classification. MC33071DR2G has a minimum supply voltage of 3V versus 1.6V for OP90GSZ-REEL. MC33071DR2G is suitable for applications operating at 3V or higher.
Q: Why does HA9P5127-5Z have a narrower operating temperature range?
A: HA9P5127-5Z is specified for 0°C to 75°C operation. This is a design characteristic of the Renesas part. Substitution is valid only when the application environment remains within this temperature window.
Q: Is OPA637AU/2K5 suitable for high-reliability applications?
A: OPA637AU/2K5 carries MSL 3 classification (168 Hours), indicating moisture sensitivity requirements during storage and handling. Applications requiring unlimited moisture exposure (MSL 1) should use MC33171DT, MC33071DR2G, or HA9P5127-5Z instead.
Q: Can all substitute parts be used in Tape & Reel packaging?
A: The OP90GSZ-REEL is supplied in Tape & Reel (TR) packaging. MC33171DT and MC33071DR2G are supplied in Cut Tape (CT) packaging. HA9P5127-5Z is supplied in Tube packaging. OPA637AU/2K5 packaging is not specified in the provided data. Packaging format does not affect electrical compatibility but may affect procurement and handling procedures.
Q: What is the key parameter difference between OP90GSZ-REEL and OPA637AU/2K5?
A: OPA637AU/2K5 has significantly higher slew rate (135 V/µs versus 0.012 V/µs) and gain bandwidth product (80 MHz versus unspecified), making it suitable for high-speed applications. However, it requires minimum 9V supply voltage and has MSL 3 classification.
Q: Are all substitute parts REACH compliant?
A: All substitute parts listed carry REACH Unaffected status, matching the OP90GSZ-REEL classification.
