Substitute Part Grouping Explanation

Substitution of the OP07DPG4 is determined by the following criteria:

Primary Substitution Parameters:

Amplifier Type: General Purpose
Number of Circuits: 1
Slew Rate: 0.3 V/µs (or lower, indicating equal or superior performance)
Gain Bandwidth Product: 600 kHz
Voltage Supply Range: 6 V to 36 V minimum compatibility
Operating Temperature Range: Must encompass or exceed 0°C to 70°C
Input Bias Current: 2 nA or lower
Input Offset Voltage: 60 µV or lower

Package Compatibility: Substitutes are grouped into two categories:

Through-Hole 8-DIP Package (direct mechanical replacement)
Surface-Mount 8-SOIC Package (functional equivalent, different mounting)

The OP07 base product number indicates all listed substitutes share the same core operational amplifier design with variations in temperature rating, packaging, and manufacturing source.

Engineering Selection Recommendations

For Direct Through-Hole Replacement (Same Package):

OP07CPZ (Analog Devices) is the primary substitute for OP07DPG4. Both devices are housed in 8-DIP through-hole packages with identical mechanical footprints. The OP07CPZ meets all electrical parameter requirements with input bias current of 1.8 nA and input offset voltage of 60 µV, matching the original specification. The OP07CPZ carries ROHS3 compliance and features an extended operating temperature range of -40°C to 85°C, providing superior thermal coverage. Inventory availability is substantial at 17,300 pieces.

OP07EPZ (Analog Devices) offers an alternative through-hole option with superior input offset voltage performance (30 µV versus 60 µV) and lower input bias current (1.2 nA). This device maintains the same 8-DIP package and operating temperature range as the original OP07DPG4 (0°C to 70°C). ROHS3 compliance is confirmed.

For Surface-Mount Applications:

OP07CDR (Texas Instruments) provides functional equivalence in an 8-SOIC surface-mount package. This device maintains identical electrical specifications to the original part (slew rate 0.3 V/µs, gain bandwidth 600 kHz, input bias current 1.8 nA, input offset voltage 60 µV). The OP07CDR is active in production with extensive inventory (220,100 pieces) and ROHS3 compliance. Selection of this part requires PCB redesign for surface-mount implementation.

Parts Not Recommended:

OP07DP (Analog Devices) is classified as obsolete and carries RoHS non-compliance status, making it unsuitable for new designs or regulated applications.

OP07DNZ (Analog Devices) requires minimum supply voltage of 8 V, exceeding the 6 V minimum of the original OP07DPG4. This specification difference may restrict application in low-voltage circuits.

Frequently Asked Questions (FAQ)

Q: Can OP07CPZ directly replace OP07DPG4 without circuit modification?

A: Yes. Both devices share identical 8-DIP through-hole package dimensions (0.300", 7.62mm), pinout, and electrical specifications within the specified operating range. No circuit modification is required for mechanical or electrical compatibility.

Q: What is the difference between OP07CDR and OP07CPZ?

A: OP07CDR uses an 8-SOIC surface-mount package, while OP07CPZ uses an 8-DIP through-hole package. Electrically, both devices meet the same performance specifications. Package selection depends on PCB assembly method and available board space.

Q: Why is OP07DP not recommended as a substitute?

A: OP07DP is classified as obsolete and does not meet ROHS3 compliance requirements. Additionally, input bias current specification (12 nA) and input offset voltage (150 µV) exceed the original OP07DPG4 parameters, indicating inferior performance characteristics.

Q: Does OP07DNZ meet the supply voltage requirements of OP07DPG4?

A: OP07DNZ requires a minimum supply voltage of 8 V, whereas OP07DPG4 operates at 6 V minimum. Applications requiring 6 V operation cannot use OP07DNZ without circuit redesign.

Q: Which substitute offers the best input offset voltage performance?

A: OP07EPZ provides the lowest input offset voltage at 30 µV, compared to 60 µV for the original OP07DPG4. This represents superior precision performance for applications sensitive to offset voltage drift.

Q: Are all recommended substitutes ROHS3 compliant?

A: All recommended substitutes (OP07CDR, OP07CPZ, OP07DNZ, OP07EPZ) carry ROHS3 compliance certification. OP07DP does not meet ROHS3 requirements and is not recommended.

Q: What is the inventory status for each substitute?

A: OP07CDR: 220,100 pieces; OP07CPZ: 17,300 pieces; OP07DNZ: 1,215 pieces; OP07EPZ: 1,404 pieces. OP07CDR offers the highest availability for immediate procurement.
