Grayhill 70-IAC5 AC Input Module – Equivalent & Substitute Parts

Part Overview

The Grayhill 70-IAC5 is an AC input module designed to convert 120VAC supply input to 5VDC output at 10mA current capacity. This component is classified as an active product and serves as an interface module in industrial control and automation systems. The module features a hold-down screw mounting style and is packaged in bulk format.

Substitute parts become necessary when the original Grayhill 70-IAC5 experiences extended lead times, inventory constraints, or when design requirements permit functional equivalents from alternative manufacturers. The Sensata Technologies IAC5 module provides electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Grayhill 70-IAC5 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Input voltage: 120VAC (fixed requirement)
• Output voltage: 5VDC (fixed requirement)
• Output current capacity: minimum 10mA
• Switching response time: 20ms turn-on and turn-off (fixed requirement)

Mechanical Compatibility Requirements:

• Mounting configuration: Hold down screw
• Color designation: Yellow
• Physical form factor: Standard style

The Sensata Technologies IAC5 module satisfies all mandatory electrical and mechanical parameters. While the Sensata part specifies 16mA output current capacity (exceeding the 10mA requirement) and 6mA input current (differing from the Grayhill specification of 8mA), these variations remain within acceptable substitution parameters for this component category. The identical switching times, voltage specifications, and mounting configuration establish functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Grayhill 70-IAC5 Selection Criteria:

• Primary choice when RoHS non-compliant components are acceptable for the application
• Preferred when bulk packaging format is required for manufacturing workflows
• Suitable for legacy system replacements or applications without RoHS mandates

Sensata Technologies IAC5 Selection Criteria:

• Required for applications subject to RoHS compliance regulations
• Appropriate when tray packaging format aligns with assembly processes
• Acceptable substitute when output current capacity of 16mA meets or exceeds circuit requirements
• Suitable for new designs or systems requiring environmental compliance certifications

Both modules maintain active product status and identical switching response characteristics. The selection between these parts depends on regulatory compliance requirements and packaging format compatibility with manufacturing operations.

Frequently Asked Questions (FAQ)

Q: Can the Sensata IAC5 directly replace the Grayhill 70-IAC5 in existing assemblies?

A: Yes, provided the application does not require RoHS non-compliant components. The Sensata IAC5 maintains identical input voltage (120VAC), output voltage (5VDC), switching times (20ms), and mounting configuration (hold down screw). The higher output current capacity (16mA versus 10mA) does not create compatibility issues.

Q: What is the significance of the different input current specifications (8mA for Grayhill versus 6mA for Sensata)?

A: The input current specification reflects the power draw from the 120VAC supply. The Sensata module draws less input current (6mA), which may provide marginal efficiency benefits in applications with multiple modules on a single supply line. This difference does not affect output performance or substitution eligibility.

Q: Does the packaging difference (Bulk versus Tray) affect component functionality?

A: No. Packaging format affects only handling, storage, and assembly line integration. Bulk and tray packaging contain identical functional components. Selection depends on manufacturing process requirements and inventory management practices.

Q: Are there any electrical performance differences between these modules?

A: Both modules deliver identical output voltage (5VDC) and switching response times (20ms on/off). The Sensata module provides higher output current capacity (16mA), which represents a performance advantage for applications requiring maximum current draw near the 10mA specification.

Q: What compliance considerations apply to substitution decisions?

A: The Grayhill 70-IAC5 is RoHS non-compliant, while the Sensata IAC5 is RoHS compliant. Applications subject to RoHS regulations (EU Directive 2011/65/EU or equivalent) require the Sensata module. Applications without RoHS mandates may use either module based on availability and packaging requirements.
