SM-IAC24 AC Input Module - Equivalent & Substitute Parts

Part Overview

The SM-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 obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning. The module features a mini-style yellow housing with 20ms response times for both turn-on and turn-off operations, suitable for industrial control and automation applications requiring AC-to-DC conversion at standardized voltage levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for AC input modules is determined by matching the following critical parameters:

• Input voltage specification (120VAC)
• Output voltage specification (24VDC)
• Output current capacity (minimum 16mA required for direct substitution)
• Response time characteristics (20ms turn-on and turn-off)
• Physical form factor (mini-style housing)

The 70M-IAC24 from Grayhill Inc. meets the core functional requirements of input/output voltage conversion and response timing. However, the output current capacity differs at 10mA versus the original 16mA specification, requiring engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The 70M-IAC24 provides functional equivalence for 120VAC to 24VDC conversion applications with matching response characteristics. The primary consideration is output current capacity: the 70M-IAC24 delivers 10mA maximum output current compared to the SM-IAC24's 16mA specification. Selection of the 70M-IAC24 is appropriate for applications where the load current requirement does not exceed 10mA. The 70M-IAC24 maintains active product status, ensuring ongoing availability and supply chain continuity. Both components share identical REACH compliance status and equivalent electrical response timing, supporting direct substitution in compliant applications where current capacity permits.

Frequently Asked Questions (FAQ)

Q: Can the 70M-IAC24 directly replace the SM-IAC24 in all applications?

A: Direct substitution is limited by output current capacity. The 70M-IAC24 provides 10mA maximum output current versus the SM-IAC24's 16mA. Substitution is valid only for applications where the connected load draws 10mA or less.

Q: What is the significance of the obsolete status of the SM-IAC24?

A: Obsolete status indicates the SM-IAC24 is no longer manufactured or supported by Sensata Technologies. The 70M-IAC24, with active product status, represents the available alternative for ongoing procurement and system maintenance.

Q: Are there packaging differences between these modules?

A: The SM-IAC24 packaging is unspecified in available documentation. The 70M-IAC24 is supplied in bulk packaging. Both maintain mini-style form factors with yellow coloring.

Q: Do both modules meet the same compliance standards?

A: Both components share REACH Unaffected status and EAR99 ECCN classification. The 70M-IAC24 is RoHS non-compliant, while the SM-IAC24 RoHS status is not specified. Applications requiring RoHS compliance require verification against specific regulatory requirements.

Q: What are the input current differences between these modules?

A: The SM-IAC24 draws 6mA input current at 120VAC, while the 70M-IAC24 draws 8mA. This 2mA difference is negligible for most power supply sizing calculations but should be verified in current-limited input scenarios.
