SM-OAC5R AC Output Module Equivalent & Substitute Parts

Part Overview

The SM-OAC5R is an AC output module manufactured by Sensata-Crydom, designed to switch AC loads with a 4.6A output capacity. The module accepts a 5VDC control signal and outputs 12–140VAC. This product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

The OACM-5H from TE Connectivity Potter & Brumfield Relays is identified as a manufacturer-recommended substitute for the SM-OAC5R. Substitution eligibility is determined by the following parameters:

• Input voltage compatibility: Both modules accept 5VDC control signals
• Input current requirement: Both modules require 20 mA
• Output module type: Both are AC output modules with mini-style packaging and black color
• Environmental compliance: Both maintain REACH Unaffected status and EAR99 ECCN classification

The OACM-5H provides enhanced output specifications (5A versus 4.6A) and extended output voltage range (24–280VAC versus 12–140VAC), making it suitable for applications requiring the SM-OAC5R's control interface and output characteristics.

Parameter Comparison

Engineering Selection Recommendations

The OACM-5H is the manufacturer-recommended substitute for the obsolete SM-OAC5R. Both modules share identical input specifications (5VDC, 20 mA) and are classified as AC output modules with equivalent environmental compliance profiles.

The OACM-5H is currently in active production status, ensuring availability for new orders and ongoing supply chain support. The module maintains REACH Unaffected compliance and EAR99 classification, consistent with the original part.

Applications operating within the SM-OAC5R's original output voltage range (12–140VAC) and current requirements (4.6A) are directly compatible with the OACM-5H, which provides higher output capacity (5A) and extended voltage range (24–280VAC). The OACM-5H's turn-on time (8.33 ms) is longer than the SM-OAC5R (0.10 ms); applications with timing-critical switching requirements must evaluate this difference against system specifications.

Frequently Asked Questions (FAQ)

Q: Can the OACM-5H directly replace the SM-OAC5R in existing applications?

A: Yes, for applications within the SM-OAC5R's original specifications. Both modules accept identical 5VDC control signals at 20 mA input current. The OACM-5H's higher output capacity (5A versus 4.6A) and extended voltage range (24–280VAC versus 12–140VAC) provide compatibility with the original design envelope. Turn-on time differs (8.33 ms versus 0.10 ms) and must be evaluated against system timing requirements.

Q: What are the key compatibility criteria for substitution?

A: Input voltage (5VDC), input current (20 mA), and AC output module type are the primary substitution criteria. Both parts meet these requirements. Output voltage range and current capacity are secondary considerations; the OACM-5H exceeds the SM-OAC5R's specifications in both parameters.

Q: Are there packaging differences between these modules?

A: The OACM-5H is supplied in tray packaging. Packaging specifications for the SM-OAC5R are not provided in the technical data. Verify packaging requirements for your application's assembly and handling processes.

Q: What is the regulatory status of the OACM-5H?

A: The OACM-5H maintains REACH Unaffected status and EAR99 ECCN classification, consistent with the SM-OAC5R. Both modules are compliant with applicable export and environmental regulations.

Q: Why is the SM-OAC5R obsolete?

A: The SM-OAC5R is classified as obsolete by the manufacturer. The OACM-5H is the active, manufacturer-recommended replacement, ensuring continued availability and technical support for new applications and component replenishment.
