Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP07EP+ is determined by strict equivalence across the following critical parameters: amplifier type (general purpose), number of circuits (1), package type (8-DIP through-hole), supply voltage range (6 V to 36 V minimum), and gain bandwidth product (600 kHz). Substitute parts are grouped into two categories based on electrical performance alignment and product status:

Category 1: Direct Electrical Equivalents (Active Status) Parts that maintain identical or near-identical electrical specifications to the OP07EP+, with active product status and current manufacturing availability. These parts satisfy the core functional requirements without design modification.

Category 2: Performance-Variant Substitutes (Active or Limited Status) Parts that operate within the same functional envelope but exhibit variations in input bias current, input offset voltage, or operating temperature range. These parts require engineering evaluation for specific application requirements but remain compatible with the 8-DIP package footprint and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: OP07EPZ

The OP07EPZ is the direct equivalent to the OP07EP+, manufactured by Analog Devices Inc. with active product status. This part maintains identical electrical specifications including 1.2 nA input bias current, 30 µV input offset voltage, 0.3 V/µs slew rate, and 600 kHz gain bandwidth product. The OP07EPZ is packaged in 8-PDIP tube format with ROHS3 compliance and unlimited moisture sensitivity rating. Current inventory of 1404 pieces supports immediate procurement. This part is the recommended first choice for direct replacement in new designs and production continuity.

Secondary Substitute: OP07CPZ

The OP07CPZ, manufactured by Analog Devices Inc., offers active product status with extended operating temperature range (-40°C to 85°C) compared to the OP07EP+ (0°C to 70°C). Input bias current increases to 1.8 nA and input offset voltage to 60 µV, representing acceptable performance degradation for applications not requiring the tighter specifications of the primary substitute. ROHS3 compliance and unlimited moisture sensitivity are maintained. Inventory of 17300 pieces provides substantial availability. This part is suitable for applications with relaxed precision requirements or extended temperature operation.

Tertiary Substitute: OP07CP

The OP07CP, manufactured by Texas Instruments, maintains active product status with identical supply voltage range and slew rate specifications. Input bias current of 1.8 nA and input offset voltage of 60 µV match the OP07CPZ performance level. Operating temperature remains 0°C to 70°C. ROHS3 compliance is confirmed. Inventory of 21974 pieces represents the highest availability among all substitutes. This part is applicable where Texas Instruments sourcing is preferred or mandated by procurement policy.

Alternative Substitute: OP07DNZ

The OP07DNZ, manufactured by Analog Devices Inc., provides active product status with extended operating temperature range (-40°C to 125°C). This part exhibits significantly lower input bias current of 200 pA and input offset voltage of 45 µV, representing superior precision performance. Slew rate reduces to 0.2 V/µs and minimum supply voltage increases to 8 V. These parameter variations require circuit design verification. ROHS3 compliance is maintained. Inventory of 1215 pieces supports limited production volumes. This part is selected for applications requiring enhanced precision and extended temperature operation within the 8 V to 36 V supply range.

Not Recommended: OP07DP and OPA177GP

The OP07DP is classified as obsolete with RoHS non-compliance, making it unsuitable for new designs or compliance-mandated applications. The OPA177GP carries Last Time Buy status, indicating discontinued manufacturing and limited future availability. Both parts should be avoided for new production commitments.

Frequently Asked Questions (FAQ)

Q1: Can OP07EPZ be used as a direct replacement for OP07EP+ without circuit modification?

A: Yes. The OP07EPZ maintains identical electrical specifications across all critical parameters: 1.2 nA input bias current, 30 µV input offset voltage, 0.3 V/µs slew rate, 600 kHz gain bandwidth product, and 6 V to 36 V supply range. Both parts use the 8-DIP through-hole package. No circuit modification is required. The primary difference is packaging format (tube versus unspecified for OP07EP+) and active product status of OP07EPZ.

Q2: What are the performance trade-offs when substituting OP07CPZ for OP07EP+?

A: The OP07CPZ introduces two electrical parameter changes: input bias current increases from 1.2 nA to 1.8 nA, and input offset voltage increases from 30 µV to 60 µV. These represent 50% and 100% increases respectively. The OP07CPZ provides extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). Applications requiring precision below 60 µV input offset voltage or input bias current below 1.8 nA should not use this substitute. All other electrical and mechanical parameters remain equivalent.

Q3: Is the OP07CP (Texas Instruments) functionally equivalent to OP07EPZ (Analog Devices)?

A: The OP07CP and OP07EPZ share identical electrical specifications: 0.3 V/µs slew rate, 600 kHz gain bandwidth product, 1.8 nA input bias current, 60 µV input offset voltage, and 6 V to 36 V supply range. Both operate at 0°C to 70°C. The primary difference is manufacturer (Texas Instruments versus Analog Devices). Both are ROHS3 compliant and use 8-DIP packaging. Selection between these parts depends on procurement policy, supply chain preference, or manufacturer qualification requirements.

Q4: Why does OP07DNZ have a higher minimum supply voltage (8 V) than OP07EP+ (6 V)?

A: The OP07DNZ is specified with an 8 V minimum supply voltage as a design parameter of that particular device variant. Circuits designed for 6 V to 7 V operation cannot use OP07DNZ without supply voltage modification. This represents a functional incompatibility for low-voltage applications. Verify supply voltage requirements before selecting OP07DNZ as a substitute.

Q5: What is the significance of "Last Time Buy" status for OPA177GP?

A: Last Time Buy status indicates that Texas Instruments has announced end-of-life for this product. Manufacturing will cease, and no new production is planned. Existing inventory may be available for a limited period. This part should not be selected for new designs or long-term production commitments. Use OPA177GP only for legacy system maintenance where no alternative exists.

Q6: Are all substitute parts ROHS3 compliant?

A: No. The OP07DP is RoHS non-compliant and should not be used in applications requiring RoHS compliance. All other substitutes (OP07EPZ, OP07CP, OP07CPZ, OP07DNZ, OPA177GP) are ROHS3 compliant. Verify RoHS compliance requirements before final part selection.

Q7: Can OP07DNZ be used in circuits designed for OP07EP+ if the supply voltage is adjusted to 8 V minimum?

A: Supply voltage adjustment alone is insufficient. The OP07DNZ exhibits different electrical characteristics: 200 pA input bias current (versus 1.2 nA), 45 µV input offset voltage (versus 30 µV), and 0.2 V/µs slew rate (versus 0.3 V/µs). These differences affect circuit performance, particularly in precision analog applications. Engineering analysis of the specific circuit is required to determine compatibility. Do not assume automatic interchangeability based on supply voltage adjustment alone.

Q8: What packaging formats are available for substitute parts?

A: All substitute parts use the 8-DIP (0.300", 7.62mm) through-hole package, maintaining mechanical compatibility with OP07EP+ PCB layouts. Packaging format variations (tube, reel, or unspecified) do not affect electrical function or board-level compatibility. Tube packaging is standard for most active substitutes and simplifies handling for manual assembly or small-volume production.
