Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO122JPE4 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Amplifier Type: Isolation
• Number of Circuits: 1
• Slew Rate: 2 V/µs
• -3dB Bandwidth: 50 kHz
• Voltage - Input Offset: 20 mV
• Current - Supply: 5 mA
• Current - Output / Channel: 15 mA
• Voltage - Supply Span: 9V to 36V
• Operating Temperature Range: -25°C to 85°C

Mechanical Specifications:

• Mounting Type: Through Hole
• Package / Case: 16-DIP (0.300", 7.62mm), 8 Leads

Compliance:

• RoHS Status: ROHS3 Compliant

The ISO122JP qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The ISO122JP is a direct functional and mechanical equivalent to the ISO122JPE4. Both components share identical electrical specifications, package geometry, and compliance certifications.

Selection Basis:

The ISO122JP is recommended as the primary substitute due to:
