OPA653IDRBR Equivalent & Substitute Parts

Part Overview

The OPA653IDRBR is a J-FET input operational amplifier manufactured by Texas Instruments, designed for high-speed signal conditioning applications. This device integrates one amplifier circuit in an 8-SON (3x3) surface mount package with exposed pad. The OPA653IDRBR is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical performance characteristics while accommodating different packaging requirements in modern production environments.

Substitute Part Grouping Explanation

Substitution of the OPA653IDRBR is determined by strict equivalence across all electrical performance parameters. The following criteria establish valid substitute relationships:

Electrical Performance Equivalence:

• Amplifier Type: J-FET (required)
• Number of Circuits: 1 (required)
• Slew Rate: 2675 V/µs (required)
• -3dB Bandwidth: 500 MHz (required)
• Current - Input Bias: 10 pA (required)
• Voltage - Input Offset: 1 mV (required)
• Current - Supply: 32 mA (required)
• Current - Output / Channel: 70 mA (required)
• Voltage - Supply Span: 7 V to 13 V (required)
• Operating Temperature Range: -40°C to 85°C (required)

Compliance & Certification Equivalence:

• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 2 (1 Year) (required)
• REACH Status: REACH Unaffected (required)

Packaging Flexibility: Package and case type may differ provided the substitute part maintains all electrical specifications and compliance certifications. Surface mount mounting type is required.

Parameter Comparison

Engineering Selection Recommendations

The OPA653IDBVT serves as a direct electrical equivalent to the OPA653IDRBR. Both parts share identical electrical performance specifications, input/output characteristics, and supply voltage requirements. The primary distinction is packaging format and product status.

Product Status Consideration: The OPA653IDRBR is classified as obsolete, while the OPA653IDBVT maintains active product status from Texas Instruments. Active status ensures continued manufacturing support, availability through authorized distribution channels, and compliance with current regulatory requirements.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for industrial and commercial applications. Moisture sensitivity level is identical at MSL 2 (1 Year), indicating equivalent handling and storage requirements.

Package Transition: The OPA653IDBVT utilizes SOT-23-5 packaging (SC-74A, SOT-753) compared to the 8-SON (3x3) package of the main part. This represents a standard package transition in semiconductor manufacturing. PCB layout modifications are required to accommodate the different pin configuration and physical dimensions.

Procurement Format: The OPA653IDBVT is supplied in Tape & Reel format, supporting automated assembly processes. The OPA653IDRBR was supplied in bulk format. Tape & Reel packaging is standard for modern production environments and provides improved component handling and traceability.

Frequently Asked Questions (FAQ)

Q: Can the OPA653IDBVT directly replace the OPA653IDRBR without circuit modification?

A: Electrical performance is identical. However, the different package type (SOT-23-5 versus 8-SON) requires PCB layout redesign. Pin assignments and physical footprints differ between packages, necessitating schematic and layout updates before implementation.

Q: What is the significance of the OPA653IDRBR being classified as obsolete?

A: Obsolete status indicates Texas Instruments has discontinued manufacturing. The OPA653IDBVT, with active status, represents the current production equivalent. Active status ensures ongoing availability, manufacturing consistency, and compliance with evolving regulatory standards.

Q: Are the electrical specifications truly identical between these parts?

A: Yes. All electrical parameters are identical: slew rate (2675 V/µs), bandwidth (500 MHz), input bias current (10 pA), input offset voltage (1 mV), supply current (32 mA), output current (70 mA), and supply voltage range (7 V to 13 V). Operating temperature range is also identical (-40°C to 85°C).

Q: What packaging format differences exist?

A: The OPA653IDRBR uses 8-SON (3x3) packaging in bulk format. The OPA653IDBVT uses SOT-23-5 packaging in Tape & Reel format. SOT-23-5 is a smaller package with different pin count and arrangement, requiring PCB redesign.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and share identical moisture sensitivity level (MSL 2, 1 Year). Regulatory and environmental compliance is equivalent.

Q: What is the inventory status for these parts?

A: The OPA653IDRBR has 2200 pieces in stock (obsolete status). The OPA653IDBVT has 1425 pieces in stock (active status). Active product status provides greater long-term availability assurance.

Q: Can I use the OPA653IDBVT in existing designs without performance degradation?

A: Electrical performance is identical, so signal conditioning characteristics remain unchanged. Physical package differences require PCB layout modifications. Once layout is updated to accommodate SOT-23-5 packaging, performance is equivalent.
