OP07DDRE4 Equivalent & Substitute Parts

Part Overview

The OP07DDRE4 is a general-purpose operational amplifier manufactured by Texas Instruments, packaged in 8-SOIC surface mount configuration. This device is classified as obsolete, indicating it has been discontinued and is no longer recommended for new designs. The OP07DDRE4 features a single amplifier circuit with low input bias current (2 nA) and low input offset voltage (60 µV), making it suitable for precision analog applications requiring low noise and high accuracy.

Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity, maintenance of existing systems, and new product development. Substitute parts must maintain electrical compatibility across critical parameters including supply voltage range, slew rate, gain bandwidth product, and thermal operating range.

Engineering Selection Recommendations

Primary Recommendation: OP07DDR

The OP07DDR is the direct equivalent to the OP07DDRE4, manufactured by Texas Instruments with active product status. This part maintains identical electrical specifications across all critical parameters: 0.3 V/µs slew rate, 600 kHz gain bandwidth product, 2 nA input bias current, and 60 µV input offset voltage. The supply voltage range (6 V to 36 V) and operating temperature range (0°C to 70°C) are identical to the original part. The OP07DDR is available in Cut Tape and Digi-Reel packaging with 25,400 units in stock, ensuring supply continuity. This part is suitable for direct replacement in existing designs without circuit modification.

Secondary Recommendation: OP07CSZ-REEL or OP07CSZ-REEL7

The OP07CSZ variants from Analog Devices Inc. are active products with enhanced specifications. These parts feature lower input bias current (1.8 nA versus 2 nA) and extended operating temperature range (-40°C to 85°C). The slew rate (0.3 V/µs) and gain bandwidth product (600 kHz) match the original specification. Supply voltage range remains 6 V to 36 V. These parts are suitable for applications requiring broader thermal operation or lower input bias current performance. Both OP07CSZ-REEL and OP07CSZ-REEL7 are active products with high inventory availability (25,202 and 25,300 units respectively).

Alternative Recommendation: OP07DRZ, OP07DRZ-REEL, or OP07DRZ-REEL7

The OP07DRZ variants offer superior performance characteristics with active product status and extended temperature range (-40°C to 125°C). These parts feature significantly lower input bias current (0.2 nA versus 2 nA) and lower input offset voltage (45 µV versus 60 µV). The slew rate is 0.2 V/µs, which is lower than the original specification but remains suitable for most general-purpose applications. The minimum supply voltage is 8 V (versus 6 V for the original), which must be verified for compatibility with existing power supply designs. These parts are recommended for new designs requiring extended thermal operation and superior precision characteristics.

Premium Recommendation: OP177FSZ, OP177FSZ-REEL, or OP177FSZ-REEL7

The OP177FSZ variants represent an enhanced alternative with active product status. These parts feature significantly lower input offset voltage (10 µV versus 60 µV) and lower input bias current (1.2 nA versus 2 nA), providing superior precision performance. The slew rate (0.3 V/µs) and gain bandwidth product (600 kHz) match the original specification. Operating temperature range is -40°C to 85°C, and supply voltage range is 6 V to 36 V. These parts are suitable for precision analog applications where lower offset voltage is beneficial. All three variants are active products with adequate inventory (7,795, 7,313, and 16,400 units respectively).

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

Frequently Asked Questions (FAQ)

Q1: Can OP07DDR be used as a direct replacement for OP07DDRE4?

Yes. The OP07DDR is manufactured by Texas Instruments and maintains identical electrical specifications across all critical parameters: slew rate (0.3 V/µs), gain bandwidth product (600 kHz), input bias current (2 nA), input offset voltage (60 µV), supply voltage range (6 V to 36 V), and operating temperature range (0°C to 70°C). The 8-SOIC package, mounting type, and compliance certifications are identical. Direct substitution is possible without circuit modification.

Q2: What is the difference between OP07CSZ and OP07CSZ-REEL variants?

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. Selection depends on manufacturing process requirements and component handling procedures. Both formats are compatible with automated assembly equipment.

Q3: Why do OP07DRZ variants have a higher minimum supply voltage (8 V) than the original OP07DDRE4 (6 V)?

The OP07DRZ variants are a different product line within the OP07 family, offering enhanced performance characteristics including lower input bias current (0.2 nA) and lower input offset voltage (45 µV). The higher minimum supply voltage (8 V) is a design characteristic of this variant. Substitution is valid only if the application power supply provides minimum 8 V. Verify power supply specifications before selecting this alternative.

Q4: Can OP177FSZ be used in place of OP07DDRE4?

OP177FSZ is a compatible substitute with enhanced precision characteristics. The slew rate (0.3 V/µs) and gain bandwidth product (600 kHz) are identical. The input offset voltage is significantly lower (10 µV versus 60 µV), and input bias current is lower (1.2 nA versus 2 nA). Supply voltage range (6 V to 36 V) and package (8-SOIC) are identical. Operating temperature range is -40°C to 85°C. Substitution is valid for applications where the enhanced precision is beneficial or neutral. Verify that the lower input offset voltage does not introduce unexpected circuit behavior in existing designs.

Q5: What is the significance of product status (Active, Not For New Designs, Obsolete)?

Product status indicates manufacturer support and availability commitment. Active parts are currently manufactured and supported for new designs. Parts marked "Not For New Designs" are still available but not recommended for new product development. Obsolete parts are discontinued and available only from existing inventory. For new designs, select only Active products. For legacy system maintenance, any compatible part with adequate inventory is acceptable.

Q6: Are all substitute parts ROHS3 compliant?

Yes. All substitute parts listed in this document are ROHS3 compliant and REACH unaffected. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating. These certifications ensure compatibility with modern manufacturing processes and environmental regulations.

Q7: What packaging options are available for substitute parts?

Substitute parts are available in multiple packaging formats: Tube (standard packaging for manual assembly), Cut Tape and Digi-Reel (for automated assembly), and Tape & Reel (for high-volume automated assembly). Selection depends on manufacturing process requirements. All packaging formats contain identical components; the difference is in presentation and handling method.

Q8: Which substitute part offers the best performance improvement over OP07DDRE4?

OP07DRZ variants offer the most significant performance improvement with input bias current of 0.2 nA (versus 2 nA) and input offset voltage of 45 µV (versus 60 µV). However, the minimum supply voltage is 8 V (versus 6 V), which must be verified for compatibility. OP177FSZ variants offer lower input offset voltage (10 µV) with identical supply voltage range. Selection depends on specific application requirements and power supply constraints.
