ISO122JUG4 Equivalent & Substitute Parts

Part Overview

The ISO122JUG4 is a linear isolation amplifier manufactured by Texas Instruments, designed for single-circuit isolation applications in 8-SOIC surface mount packaging. This component provides galvanic isolation with a 50 kHz bandwidth and operates across a 9V to 36V supply range.

The ISO122JUG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring isolation amplification functionality with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO122JUG4 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Amplifier type (Isolation), number of circuits (1), slew rate (2 V/µs), bandwidth (-3dB at 50 kHz), input offset voltage (20 mV), supply current (5 mA), output current per channel (15 mA), and supply voltage range (9V to 36V minimum, 36V maximum).

Mechanical Specifications: Package type (8-SOIC with 0.295" width, 7.50mm), mounting type (Surface Mount), and lead count (8 Leads).

Compliance & Environmental: RoHS3 compliance, MSL rating (3), REACH status, and operating temperature range (-25°C to 85°C).

Substitute parts must match all specified parameters without deviation. Packaging format differences (tube versus other formats) do not affect functional equivalence when electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

The ISO122JU serves as the direct functional equivalent to the discontinued ISO122JUG4. Both components are manufactured by Texas Instruments and share identical electrical performance specifications, mechanical packaging, and environmental compliance certifications.

The primary distinction is product status: ISO122JUG4 is discontinued, while ISO122JU maintains active production status. This availability difference makes ISO122JU the appropriate selection for new designs and ongoing production requirements.

Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with standard surface mount assembly processes and environmental regulations. The 8-SOIC package format and surface mount configuration remain consistent across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can ISO122JU be used as a direct replacement for ISO122JUG4 in existing designs?

A: Yes. ISO122JU is electrically and mechanically equivalent to ISO122JUG4. All specified parameters—including amplifier type, circuit count, bandwidth, slew rate, supply voltage range, output current, and package configuration—are identical. The components are pin-compatible and functionally interchangeable.

Q: What is the difference between ISO122JUG4 and ISO122JU?

A: The primary difference is product status. ISO122JUG4 is discontinued at DiGi Electronics, while ISO122JU is in active production. Electrical specifications, mechanical packaging, and compliance certifications are identical.

Q: Are there packaging format differences between these parts?

A: ISO122JUG4 packaging format is not specified in available data. ISO122JU is supplied in Tube packaging. Both use the same 8-SOIC physical package. Packaging format does not affect electrical performance or PCB assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ISO122JUG4 and ISO122JU are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (3, 168 Hours). They meet the same environmental and regulatory requirements.

Q: What is the operating temperature range for these isolation amplifiers?

A: Both parts operate across -25°C to 85°C. This range applies to all electrical specifications and performance parameters.

Q: Can these parts be used interchangeably in surface mount assembly?

A: Yes. Both components use identical 8-SOIC surface mount packaging with 0.295" width and 7.50mm dimensions. Assembly processes, reflow profiles, and PCB layout requirements are identical.
