ISL28107FBZ Equivalent & Substitute Parts

Part Overview

The ISL28107FBZ is a general-purpose operational amplifier manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The ISL28107FBZ delivers a single amplifier circuit with a 1 MHz gain-bandwidth product and operates across a wide supply voltage range of 4.5 V to 40 V, making it suitable for general-purpose analog signal conditioning applications.

Due to its obsolete status, identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements. Active alternative components with compatible electrical and mechanical specifications are available from established manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL28107FBZ are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Mechanical Compatibility:

• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Pin count and footprint alignment

Electrical Compatibility:

• Amplifier type: General Purpose
• Number of circuits: 1
• Operating temperature range: -40°C ~ 125°C
• Supply voltage range overlap

Regulatory Compliance:

• RoHS3 compliance
• REACH unaffected status
• ECCN and HTSUS classification alignment

The OP1177ARZ, OP1177ARZ-REEL, and OP1177ARZ-REEL7 devices from Analog Devices Inc. meet these substitution criteria. All three variants share identical electrical specifications and differ only in packaging format (Tube, Tape & Reel, and Cut Tape & Digi-Reel respectively). These parts are active products with established supply availability.

Parameter Comparison

Engineering Selection Recommendations

The OP1177ARZ family from Analog Devices Inc. provides direct functional substitution for the obsolete ISL28107FBZ. All three packaging variants (OP1177ARZ, OP1177ARZ-REEL, OP1177ARZ-REEL7) are active products with full regulatory compliance and superior moisture sensitivity ratings.

Selection Criteria by Application:

OP1177ARZ (Tube Packaging): Suitable for low-volume applications, prototype development, and manual assembly processes. Inventory availability: 4,699 pieces.

OP1177ARZ-REEL (Tape & Reel Packaging): Appropriate for standard automated assembly operations requiring conventional reel formats. Inventory availability: 2,260 pieces.

OP1177ARZ-REEL7 (Cut Tape & Digi-Reel Packaging): Optimal for high-volume production and flexible assembly requirements. Highest inventory availability: 20,300 pieces.

All substitute parts maintain identical electrical performance characteristics within the general-purpose amplifier category, operate across the full industrial temperature range, and comply with ROHS3 and REACH requirements. The transition from ISL28107FBZ to OP1177ARZ variants eliminates obsolescence risk while maintaining design compatibility at the functional level.

Frequently Asked Questions (FAQ)

Q: Can OP1177ARZ devices directly replace ISL28107FBZ in existing PCB designs?

A: Yes. The OP1177ARZ family shares identical 8-SOIC package geometry and pin configuration with the ISL28107FBZ. No PCB layout modifications are required. Electrical performance is functionally equivalent for general-purpose amplifier applications.

Q: What are the differences between OP1177ARZ, OP1177ARZ-REEL, and OP1177ARZ-REEL7?

A: These three part numbers represent the same die and electrical specifications packaged in different formats. OP1177ARZ is supplied in Tube packaging for manual handling. OP1177ARZ-REEL is supplied on standard Tape & Reel format. OP1177ARZ-REEL7 is supplied on Cut Tape & Digi-Reel format. Selection depends on assembly process requirements and volume.

Q: Are there electrical performance differences between ISL28107FBZ and OP1177ARZ?

A: The OP1177ARZ exhibits higher slew rate (0.7 V/µs vs. 0.32 V/µs) and greater gain-bandwidth product (1.3 MHz vs. 1 MHz). Input bias current is higher (500 pA vs. 15 pA). Output current capability is lower (10 mA vs. 40 mA). These differences are within acceptable ranges for general-purpose amplifier applications but should be evaluated for specific circuit requirements.

Q: What is the supply voltage compatibility between ISL28107FBZ and OP1177ARZ?

A: ISL28107FBZ operates from 4.5 V to 40 V. OP1177ARZ operates from 5 V to 36 V. The OP1177ARZ minimum supply voltage is 0.5 V higher and maximum is 4 V lower. Designs operating at the extremes of the ISL28107FBZ range require circuit evaluation.

Q: Are all OP1177ARZ variants RoHS3 compliant?

A: Yes. OP1177ARZ, OP1177ARZ-REEL, and OP1177ARZ-REEL7 are all ROHS3 compliant and REACH unaffected, matching the regulatory status of the ISL28107FBZ.

Q: Which OP1177ARZ variant should be selected for new production designs?

A: OP1177ARZ-REEL7 is recommended for new production due to highest inventory availability (20,300 pieces), compatibility with modern automated assembly equipment, and superior moisture sensitivity rating (MSL 1 vs. MSL 2).

Q: Is the ISL28107FBZ still available for purchase?

A: ISL28107FBZ is classified as obsolete. While 840 pieces are currently in stock, future availability is not guaranteed. Transition to active OP1177ARZ variants is recommended for design continuity and supply chain security.
