M-IAC24 AC Input Module - Equivalent & Substitute Parts

Part Overview

The M-IAC24 is an AC input module manufactured by Sensata-Crydom, designed to convert 120VAC supply input to 24VDC output at 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.

Key Parameters

Substitute Part Grouping Explanation

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

• Input Voltage: 120VAC (fixed requirement)
• Output Voltage: 24VDC (fixed requirement)
• Output Current Capacity: Minimum 16mA required
• Response Time: 20ms turn-on and turn-off (fixed requirement)
• Form Factor: Mini-style housing
• Regulatory Compliance: REACH Unaffected, ECCN EAR99

The substitute part 70M-IAC24 meets these core electrical and mechanical specifications, enabling direct functional replacement in applications requiring 120VAC to 24VDC conversion with the specified performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 70M-IAC24 (Grayhill Inc.) is available as an active product with current manufacturing support, providing supply chain continuity for the obsolete M-IAC24. Both parts maintain identical input/output voltage specifications, response timing, and regulatory compliance status.

The 70M-IAC24 operates at 8mA input current versus the M-IAC24's 6mA, and delivers 10mA output current versus 16mA. Applications requiring the full 16mA output capacity of the original M-IAC24 must evaluate whether the 10mA output of the 70M-IAC24 satisfies system requirements. The 70M-IAC24 carries RoHS non-compliant status, which may impact procurement decisions in regulated environments.

Frequently Asked Questions (FAQ)

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

A: Direct replacement is possible only in applications where 10mA output current is sufficient. The M-IAC24 provides 16mA output capacity; the 70M-IAC24 provides 10mA. Verify your circuit's current requirements before substitution.

Q: Are the physical dimensions and mounting compatible?

A: Both parts feature mini-style yellow housing. Mechanical compatibility should be confirmed through detailed dimensional drawings, as "mini-style" classification does not guarantee identical form factors.

Q: What is the difference in input current consumption?

A: The M-IAC24 draws 6mA input current while the 70M-IAC24 draws 8mA. This difference may impact power supply sizing in applications with multiple modules.

Q: Does the 70M-IAC24 meet RoHS requirements?

A: No. The 70M-IAC24 is RoHS non-compliant. If RoHS compliance is mandatory for your application, this substitute is not suitable.

Q: Are both parts REACH compliant?

A: Both parts carry REACH Unaffected status, indicating they are not subject to REACH restrictions.
