Substitute Part Grouping Explanation

Substitution eligibility for the ACPL-C790-500E is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Amplifier Type: Isolation
• Number of Circuits: 1
• Output Type: Differential
• -3dB Bandwidth: 200 kHz
• Current - Input Bias: 100 nA
• Current - Output / Channel: 11 mA
• Operating Temperature Range: -40°C to 105°C
• Mounting Type: Surface Mount
• Package Type: 8-SOIC (8-SO Stretched)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Parameter Variations: Substitute parts may differ in the following parameters within acceptable engineering tolerances:

• Voltage - Input Offset: 200 µV (substitute) vs. 600 µV (main part) — improved specification
• Current - Supply: 19 mA (substitute) vs. 13 mA (main part) — higher consumption acceptable
• Voltage - Supply Span (Min): 3 V (substitute) vs. 4.5 V (main part) — wider input range acceptable
• Package / Case physical dimensions: 8-SOIC (0.535", 13.60mm Width) (substitute) vs. 8-SOIC (0.268", 6.81mm Width) (main part) — different SOIC body width
• Packaging Format: Tape & Reel (TR) or unspecified vs. Cut Tape (CT) & Digi-Reel®

The identified substitutes ACNT-H790-500E and ACNT-H79A-500E meet all mandatory equivalence criteria while maintaining functional compatibility in isolation amplifier circuit applications.

Parameter Comparison

Engineering Selection Recommendations

ACPL-C790-500E (Primary Part)

The ACPL-C790-500E is the primary reference component with Active product status and full regulatory compliance. This part is suitable for applications requiring the specified 4.5 V to 5.5 V supply voltage range and 13 mA supply current profile. The 600 µV input offset voltage specification applies to this variant.

ACNT-H790-500E (Substitute - Manufacturer Recommended)

The ACNT-H790-500E is designated as a manufacturer-recommended substitute. This part maintains identical functional performance across all critical isolation amplifier parameters. Key differences include improved input offset voltage specification (200 µV), wider supply voltage range (3 V to 5.5 V minimum), and higher supply current requirement (19 mA). The physical package body width differs (13.60mm vs. 6.81mm), requiring PCB layout verification. Packaging format is Tape & Reel (TR). Active product status and ROHS3 compliance are maintained.

ACNT-H79A-500E (Substitute - Manufacturer Recommended)

The ACNT-H79A-500E is designated as a manufacturer-recommended substitute with identical functional specifications to ACNT-H790-500E. This part provides the same improved input offset voltage (200 µV), wider supply voltage range (3 V minimum), and 19 mA supply current. Physical package dimensions match ACNT-H790-500E (13.60mm body width). Packaging format is unspecified. Active product status and ROHS3 compliance are maintained.

Selection Criteria:

• Use ACPL-C790-500E when the 4.5 V minimum supply voltage and 13 mA supply current are design requirements, and the narrower 6.81mm SOIC body width is necessary for PCB layout constraints.
• Use ACNT-H790-500E or ACNT-H79A-500E when the wider supply voltage range (3 V minimum) is beneficial, improved input offset voltage (200 µV) is advantageous, and the 13.60mm SOIC body width is compatible with PCB layout.
• All three parts maintain identical isolation amplifier functionality, differential output configuration, 200 kHz bandwidth, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ACNT-H790-500E or ACNT-H79A-500E be used as direct replacements for ACPL-C790-500E?

A: Both ACNT-H790-500E and ACNT-H79A-500E are functionally equivalent substitutes for isolation amplifier applications. However, the physical package body width differs (13.60mm vs. 6.81mm), requiring verification that PCB footprint and layout accommodate the wider SOIC body. Electrical performance is equivalent across all critical parameters.

Q: What is the difference between ACNT-H790-500E and ACNT-H79A-500E?

A: Both parts share identical electrical specifications and functional performance. The primary difference is packaging format designation: ACNT-H790-500E is specified as Tape & Reel (TR), while ACNT-H79A-500E packaging format is unspecified in the provided data. Electrical and thermal characteristics are equivalent.

Q: Why does the substitute part have a lower minimum supply voltage (3 V vs. 4.5 V)?

A: The substitute parts ACNT-H790-500E and ACNT-H79A-500E feature a wider supply voltage operating range (3 V to 5.5 V) compared to the primary part (4.5 V to 5.5 V). This represents an expanded specification that provides greater design flexibility for applications requiring lower supply voltages while maintaining full functional performance.

Q: Does the improved input offset voltage (200 µV vs. 600 µV) affect circuit design?

A: The substitute parts feature improved input offset voltage specifications (200 µV) compared to the primary part (600 µV). This represents a tighter specification that reduces DC offset error in signal conditioning applications. Circuits designed for the 600 µV specification will operate within acceptable parameters with the 200 µV substitute parts.

Q: What is the impact of higher supply current (19 mA vs. 13 mA) in the substitute parts?

A: The substitute parts ACNT-H790-500E and ACNT-H79A-500E require 19 mA supply current compared to 13 mA for the primary part. Power supply design must accommodate this increased current draw. Total power dissipation increases proportionally with the higher supply current at equivalent operating voltages.

Q: Are all three parts RoHS3 compliant?

A: Yes. ACPL-C790-500E, ACNT-H790-500E, and ACNT-H79A-500E are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). All parts meet REACH unaffected status and EAR99 export classification.

Q: What PCB layout considerations apply when substituting between these parts?

A: The primary consideration is physical package body width. ACPL-C790-500E uses 8-SOIC with 6.81mm body width, while ACNT-H790-500E and ACNT-H79A-500E use 8-SOIC with 13.60mm body width. PCB footprint, trace routing, and component spacing must be verified to accommodate the wider body dimension. Pin configuration and electrical connections remain identical across all three parts.
