M-OAC5 AC Output Module Equivalent & Substitute Parts

Part Overview

The M-OAC5 is an AC output module manufactured by Sensata-Crydom, designed to switch AC loads with a 4.6A output capacity. This module accepts a 5VDC control signal and provides galvanic isolation between the control circuit and the AC output stage. The product is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when inventory constraints, lead time requirements, or specific application parameters necessitate alternative sourcing while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The 70M-OAC5 manufactured by Grayhill Inc. is identified as a direct substitute based on the following allowable parameter alignment:

Matching Parameters:

• Input voltage: 5VDC (identical)
• Output voltage range: 24 ~ 140VAC (overlaps with 12 ~ 140VAC specification)
• Switching timing: 8.33ms turn-on and turn-off (identical)
• Form factor: Mini style (identical)
• Product status: Active (identical)
• ECCN and HTSUS classifications: Identical

Allowable Variations:

• Output current: 3A (substitute) versus 4.6A (main part) — the substitute provides reduced current capacity, suitable for applications requiring ≤3A
• Input current: 16 mA (substitute) versus 20 mA (main part) — the substitute draws lower control current
• Output voltage minimum: 24VAC (substitute) versus 12VAC (main part) — the substitute does not support 12VAC operation
• Packaging: Bulk (substitute) versus Tray (main part) — packaging format differs but does not affect electrical function
• RoHS Status: RoHS non-compliant (substitute) versus ROHS3 compliant (main part) — compliance differs

Parameter Comparison

Engineering Selection Recommendations

M-OAC5 (Sensata-Crydom): Select this part when ROHS3 compliance is a mandatory requirement, when output current demand reaches 4.6A, or when the application requires AC output voltage operation beginning at 12VAC. This part is the primary choice for regulated supply chains with RoHS certification requirements.

70M-OAC5 (Grayhill Inc.): Select this part when output current requirements do not exceed 3A, when the minimum AC output voltage is 24VAC or higher, and when RoHS compliance is not a contractual or regulatory requirement. This substitute is suitable for applications with lower current demands and simplified compliance frameworks. The lower input current draw (16 mA versus 20 mA) may provide marginal benefits in power-constrained control circuits.

Both parts share identical switching response times and input voltage specifications, ensuring functional compatibility in timing-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the 70M-OAC5 replace the M-OAC5 in all applications?

A: No. The 70M-OAC5 has three limiting factors: maximum output current of 3A (versus 4.6A), minimum output voltage of 24VAC (versus 12VAC), and RoHS non-compliance. Substitution is valid only when the application operates at ≤3A output current, requires minimum AC voltage of 24VAC or higher, and does not mandate RoHS3 certification.

Q: What is the impact of the packaging difference between Tray and Bulk?

A: Packaging format affects handling, storage, and supply chain logistics but does not alter electrical performance or pin compatibility. Tray packaging provides individual component protection; Bulk packaging reduces per-unit cost for high-volume procurement. Both formats are suitable for automated assembly processes.

Q: Why does the 70M-OAC5 have a lower input current specification?

A: The 70M-OAC5 draws 16 mA versus 20 mA for the M-OAC5. This difference reflects internal circuit design variations between manufacturers. Both values are within typical control signal current ranges for 5VDC logic circuits and do not affect compatibility with standard microcontroller or PLC outputs.

Q: Is the 70M-OAC5 suitable for 12VAC output applications?

A: No. The 70M-OAC5 output voltage range begins at 24VAC. Applications requiring 12VAC output must use the M-OAC5 or identify alternative parts with 12VAC minimum specifications.

Q: What compliance considerations apply when selecting between these parts?

A: The M-OAC5 carries ROHS3 compliance certification; the 70M-OAC5 does not. Both parts are REACH unaffected. If your application, customer contract, or regional regulation mandates RoHS compliance, the M-OAC5 is the required selection. Both parts share identical ECCN and HTSUS classifications for export control and tariff purposes.
