OP-07DPS Equivalent & Substitute Parts Reference

Part Overview

The OP-07DPS is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SO surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory (4238 pcs). The OP-07DPS serves applications requiring low-noise, precision amplification across industrial and commercial temperature ranges (0°C to 70°C). Identification of equivalent substitute parts is necessary due to the Last Time Buy status and to ensure long-term design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP-07DPS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Slew Rate: 0.3 V/µs
• Gain Bandwidth Product: 600 kHz
• Voltage Supply Span: 6 V (Min) to 36 V (Max)
• Operating Temperature Range: 0°C to 70°C

Mechanical & Environmental Equivalence Criteria:

• Mounting Type: Surface Mount
• Package Family: 8-SOIC (both 0.209" and 0.154" widths are functionally equivalent 8-SOIC variants)
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The OP07CDR meets all substitution criteria and is designated as the manufacturer-recommended equivalent. Both parts share the same base product number (OP-07) and are manufactured by Texas Instruments, ensuring design compatibility and functional interchangeability.

Engineering Selection Recommendations

Primary Recommendation: OP07CDR

The OP07CDR is the direct substitute for the OP-07DPS. Selection rationale is based on the following engineering factors:

1. Product Status Alignment: The OP07CDR maintains Active product status, ensuring continued availability and long-term supply chain stability, whereas the OP-07DPS is Last Time Buy with finite inventory.

2. Electrical Equivalence: All critical electrical parameters are identical, including slew rate (0.3 V/µs), gain bandwidth product (600 kHz), and supply voltage range (6 V to 36 V). No circuit redesign is required.

3. Compliance Certification: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications.

4. Packaging Compatibility: Both parts use 8-SOIC surface mount packages. The OP07CDR employs a narrower body variant (0.154" vs. 0.209" width), which is mechanically compatible with standard 8-SOIC PCB footprints and may offer improved board density.

5. Moisture Sensitivity: Both parts carry MSL Level 1 (Unlimited), indicating no moisture-related handling restrictions during assembly and storage.

Implementation Path: Direct substitution of OP07CDR for OP-07DPS requires no circuit modifications, PCB layout changes, or firmware updates. The parts are pin-compatible and functionally equivalent.

Frequently Asked Questions (FAQ)

Q1: Can OP07CDR be used as a direct replacement for OP-07DPS without circuit modifications?

A: Yes. The OP07CDR is electrically and functionally equivalent to the OP-07DPS across all specified parameters. No circuit redesign, component value changes, or PCB layout modifications are required. Both parts are pin-compatible 8-SOIC devices with identical electrical performance.

Q2: What is the difference between the 8-SO package of OP-07DPS and the 8-SOIC package of OP07CDR?

A: Both designations refer to 8-pin surface mount packages. The primary difference is body width: OP-07DPS uses 0.209" (5.30mm) width, while OP07CDR uses 0.154" (3.90mm) width. Both are compatible with standard 8-SOIC PCB footprints. The narrower body of OP07CDR may provide improved board density without affecting electrical performance.

Q3: Why is OP-07DPS classified as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the OP-07DPS. Existing inventory (4238 pcs) represents the final available stock. The OP07CDR, with Active status and significantly higher inventory (220100 pcs), is the recommended long-term alternative.

Q4: Are there any differences in input bias current or input offset voltage between these parts?

A: The OP07CDR specifies Input Bias Current (1.8 nA) and Input Offset Voltage (60 µV). These parameters were not provided for the OP-07DPS in the reference data. Both parts share the same base product number (OP-07) and are manufactured by Texas Instruments, indicating equivalent performance characteristics.

Q5: What is the minimum order quantity or lead time for OP07CDR?

A: This information is not included in the provided engineering reference data. Contact the supplier or Texas Instruments directly for current lead times, minimum order quantities, and packaging options (Cut Tape or Digi-Reel).

Q6: Are both parts suitable for high-temperature applications above 70°C?

A: No. Both the OP-07DPS and OP07CDR are specified for operating temperatures from 0°C to 70°C. Applications requiring operation above 70°C require alternative components with extended temperature ratings.

Q7: Do these parts require special handling or storage conditions?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions. Standard ESD precautions for surface mount components apply. Refer to Texas Instruments datasheets for detailed storage and handling requirements.
