IAC24 AC Input Module 120V - Equivalent & Substitute Parts

Part Overview

The IAC24 is an AC input module manufactured by Sensata Technologies, designed to convert 120VAC supply to 24VDC output with 16mA capacity. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Finding equivalent substitute parts is necessary for maintenance, repair, and legacy system support where original components are unavailable or inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IAC24 is determined by the following critical parameters:

• Input/Output Voltage: Must match 120VAC input and 24VDC output
• Output Current Capacity: Must meet or exceed 16mA requirement
• Switching Times: Turn on and turn off times must be compatible with system timing requirements
• Physical Form Factor: Hold down screw feature and standard style ensure mechanical compatibility
• Packaging Compatibility: Tray or bulk packaging acceptable for equivalent function

Two substitute parts meet these criteria with documented compatibility:

IAC-24 (TE Connectivity Potter & Brumfield Relays): Matches all voltage specifications with 18mA output capacity, exceeding the 16mA requirement. Turn on time identical at 20ms; turn off time extended to 30ms.

70-IAC24 (Grayhill Inc.): Matches all voltage specifications with 10mA output capacity, which is below the 16mA requirement but may be acceptable in applications with reduced current demand. Switching times match the original specification at 20ms both directions.

Parameter Comparison

Engineering Selection Recommendations

IAC-24 (TE Connectivity Potter & Brumfield Relays) is the primary substitute for new procurement and replacement applications. This part maintains active product status, ensuring ongoing availability and manufacturer support. Output current capacity of 18mA exceeds the original 16mA specification, providing operational margin. RoHS3 compliance and REACH affected status align with current environmental regulations. The extended turn off time of 30ms versus 20ms must be evaluated against system timing requirements.

70-IAC24 (Grayhill Inc.) serves as a secondary substitute where output current requirements are reduced or where the lower 10mA capacity is acceptable for the application. This part maintains active product status. However, RoHS non-compliance status may restrict use in regulated industries or new system designs. REACH unaffected status indicates fewer environmental restrictions in certain markets.

Both substitutes maintain identical input voltage, output voltage, and physical form factor compatibility with the original IAC24.

Frequently Asked Questions (FAQ)

Q: Can IAC-24 directly replace IAC24 in all applications? A: IAC-24 meets all voltage and physical compatibility requirements. The 18mA output capacity exceeds the original 16mA specification. The extended turn off time (30ms vs. 20ms) must be verified against system timing constraints before deployment.

Q: What is the difference in output current between the three parts? A: IAC24 provides 16mA, IAC-24 provides 18mA, and 70-IAC24 provides 10mA. Selection depends on the actual current demand of the connected load. IAC-24 offers the highest capacity margin.

Q: Are there packaging differences between these parts? A: IAC24 is supplied in tray packaging. IAC-24 and 70-IAC24 are supplied in bulk packaging. Both packaging formats are compatible with standard component handling and installation procedures.

Q: Why is IAC24 marked "Not For New Designs"? A: This status indicates the manufacturer has discontinued active development and recommends alternative parts for new applications. Existing inventory remains available for legacy system support and maintenance.

Q: What compliance certifications should I consider? A: IAC-24 holds RoHS3 and REACH affected certifications, meeting current environmental standards. 70-IAC24 is RoHS non-compliant and REACH unaffected. Regulatory requirements for your application determine which certification status is acceptable.

Q: Do the switching times affect system performance? A: Turn on time is identical across all three parts at 20ms. Turn off time differs: IAC24 and 70-IAC24 at 20ms, IAC-24 at 30ms. Applications with strict timing requirements must account for the extended turn off time of IAC-24.
