Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS774KUG4 are determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for substitution validity:

• 12-bit resolution
• 125 kSPS sampling rate
• Single-ended input configuration
• Parallel data interface
• SAR architecture
• External and internal reference capability
• 5V analog and digital supply voltage specifications
• -40°C to 85°C operating temperature range
• 28-SOIC surface mount package
• ROHS3 compliance

The ADS774HIBDW and ADS774HIDW meet all these criteria and are direct parametric equivalents of the ADS774KUG4.

Parameter Comparison

Engineering Selection Recommendations

The ADS774KUG4 is discontinued at DiGi Electronics. Both ADS774HIBDW and ADS774HIDW are marked as "Not For New Designs" but remain available in inventory and maintain full parametric equivalence with the original part.

Selection between substitute parts should be based on:

Packaging consideration: Both substitutes are supplied in Tube packaging, whereas the original part number does not specify packaging type.

Moisture Sensitivity Level (MSL): The ADS774KUG4 carries MSL 3 (168 Hours), while both substitutes carry MSL 2 (1 Year). This represents improved moisture handling characteristics in the substitute parts.

Compliance: All three parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory equivalence.

Inventory availability: ADS774HIBDW (1900 pcs) and ADS774HIDW (1076 pcs) both exceed the original part's inventory (1030 pcs).

Frequently Asked Questions (FAQ)

Q: Can ADS774HIBDW and ADS774HIDW be used interchangeably with ADS774KUG4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, operating ranges, and 28-SOIC package dimensions. They are direct substitutes for the discontinued ADS774KUG4.

Q: What is the difference between ADS774HIBDW and ADS774HIDW?

A: Both parts are parametric equivalents. The difference lies in their product status designation ("Not For New Designs"), but both maintain identical electrical and mechanical specifications for substitution purposes.

Q: Does the improved MSL rating (2 vs. 3) affect compatibility?

A: No. MSL 2 (1 Year) is superior to MSL 3 (168 Hours), indicating better moisture resistance. This does not affect electrical or mechanical compatibility.

Q: Are the substitute parts available in different packaging options?

A: Both ADS774HIBDW and ADS774HIDW are supplied in Tube packaging. The original ADS774KUG4 packaging type is not specified in the available data.

Q: Do all three parts meet the same compliance standards?

A: Yes. ADS774KUG4, ADS774HIBDW, and ADS774HIDW are all ROHS3 compliant and REACH Unaffected, ensuring equivalent regulatory compliance.
