Engineering Selection Recommendations

Primary Recommendation: OP07CDR

The OP07CDR is the manufacturer-recommended direct replacement for the obsolete OP07CDRG4. Both devices are manufactured by Texas Instruments and maintain identical electrical specifications across all critical parameters: 0.3 V/µs slew rate, 600 kHz gain bandwidth product, 1.8 nA input bias current, and 60 µV input offset voltage. The OP07CDR is currently in active production status with substantial inventory availability (220,100 pieces), ensuring supply chain continuity. Both parts operate across the 6V to 36V supply range and are housed in the same 8-SOIC package. The OP07CDR is ROHS3 compliant and carries identical regulatory certifications.

Secondary Recommendation: OP07CSZ-REEL or OP07CSZ-REEL7

The OP07CSZ-REEL and OP07CSZ-REEL7 variants, manufactured by Analog Devices Inc., provide identical electrical performance to the OP07CDRG4 with an extended operating temperature range of -40°C to 85°C compared to the original 0°C to 70°C specification. These devices maintain the same 0.3 V/µs slew rate, 600 kHz bandwidth, 1.8 nA input bias current, and 60 µV input offset voltage. Both variants are in active production status with good inventory levels (25,202 and 25,300 pieces respectively) and are supplied in Cut Tape and Digi-Reel packaging. Selection between OP07CSZ-REEL and OP07CSZ-REEL7 depends on specific reel configuration requirements for automated assembly processes.

Alternative Consideration: LT1012 Series

The LT1012ACS8#TRPBF, LT1012IS8#PBF, and LT1012IS8#TRPBF devices offer superior input bias current performance (25 pA versus 1.8 nA) and lower input offset voltage (8 µV versus 60 µV). However, these devices exhibit a lower slew rate of 0.2 V/µs and operate across a different supply voltage range (2.4V to 40V). The LT1012 series is suitable for applications where lower input bias current and offset voltage are critical requirements and where the reduced slew rate does not compromise system performance. All LT1012 variants are in active production status.

Compliance and Regulatory Status:

All recommended substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH unaffected status, ensuring compatibility with current manufacturing and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the OP07CDR be used as a direct replacement for the OP07CDRG4?

A: Yes. The OP07CDR is the manufacturer-recommended direct replacement. Both devices share identical electrical specifications, including 0.3 V/µs slew rate, 600 kHz gain bandwidth product, 1.8 nA input bias current, and 60 µV input offset voltage. Both operate across the 6V to 36V supply range and are packaged in 8-SOIC surface mount configuration. The primary difference is product status: OP07CDRG4 is obsolete while OP07CDR is in active production.

Q: What is the difference between OP07CSZ and OP07CSZ-REEL?

A: The electrical specifications are identical between OP07CSZ and OP07CSZ-REEL. The primary difference is packaging format: OP07CSZ is supplied in Tube packaging, while OP07CSZ-REEL and OP07CSZ-REEL7 are supplied in Cut Tape and Digi-Reel format suitable for automated assembly processes. Selection depends on manufacturing process requirements and handling equipment compatibility.

Q: Are the LT1012 devices suitable replacements for the OP07CDRG4?

A: The LT1012 series offers superior input bias current (25 pA) and input offset voltage (8 µV) performance compared to the OP07CDRG4 (1.8 nA and 60 µV respectively). However, the LT1012 exhibits a lower slew rate of 0.2 V/µs versus 0.3 V/µs. Substitution is appropriate only when the enhanced input characteristics are required and the reduced slew rate does not degrade system performance. The LT1012 operates across a 2.4V to 40V supply range, which differs from the OP07CDRG4 specification.

Q: What is the operating temperature range difference between OP07CDR and OP07CSZ-REEL?

A: The OP07CDR operates across 0°C to 70°C, matching the original OP07CDRG4 specification. The OP07CSZ-REEL extends the operating range to -40°C to 85°C. Selection between these devices depends on application temperature requirements. For applications requiring extended low-temperature operation or higher temperature tolerance, the OP07CSZ-REEL is appropriate.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed—OP07CDR, OP07CSZ, OP07CSZ-REEL, OP07CSZ-REEL7, and all LT1012 variants—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: What packaging options are available for the OP07 series substitutes?

A: The OP07CDR is available in Cut Tape and Digi-Reel packaging. The OP07CSZ is supplied in Tube format. The OP07CSZ-REEL and OP07CSZ-REEL7 are supplied in Cut Tape and Digi-Reel format. All variants maintain the 8-SOIC (0.154", 3.90mm Width) surface mount package configuration, ensuring mechanical compatibility with the original OP07CDRG4 footprint.

Q: Can OP07CSZ be used in new designs?

A: The OP07CSZ is designated as "Not For New Designs" by the manufacturer. While it remains functionally equivalent to the OP07CDRG4, Analog Devices recommends using OP07CSZ-REEL or OP07CSZ-REEL7 for new design implementations. These variants are in active production status and provide identical electrical performance with extended operating temperature range.
