SM-ODC5MA DC Output Module Equivalent & Substitute Parts

Part Overview

The SM-ODC5MA is a DC output module manufactured by Sensata-Crydom, designed to switch DC loads up to 3A with input supply of 5VDC. This module operates across an output voltage range of 1 to 200VDC with switching times of 1ms turn-on and 0.05ms turn-off. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The 70M-ODC5A from Grayhill Inc. qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Input voltage: 5VDC
• Input current: 18 mA
• Output current: 3A
• Output voltage range: 4 ~ 200VDC (encompasses the SM-ODC5MA range of 1 ~ 200VDC for practical applications above 4VDC)
• Product type: DC Output Module
• Style: Mini
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitution Basis: The 70M-ODC5A maintains electrical compatibility across input/output specifications and physical form factor. Both modules are designed for identical control signal levels (5VDC) and load switching capacity (3A). The output voltage floor difference (4VDC vs. 1VDC minimum) represents a practical constraint only for applications requiring switching below 4VDC.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement: The 70M-ODC5A is the designated substitute for SM-ODC5MA applications. The substitute maintains active product status with Grayhill Inc., ensuring ongoing availability and technical support. Both modules carry identical REACH compliance classification and moisture sensitivity ratings, supporting direct substitution in existing designs.

Compliance Considerations: The 70M-ODC5A is RoHS non-compliant, whereas the SM-ODC5MA compliance status is not specified. Applications subject to RoHS requirements must evaluate this distinction before implementation.

Switching Performance: The 70M-ODC5A exhibits faster turn-on response (0.075ms vs. 1ms) but slower turn-off response (0.75ms vs. 0.05ms). Applications with critical timing requirements must assess whether these timing differences impact system performance.

Frequently Asked Questions (FAQ)

Q: Can the 70M-ODC5A directly replace the SM-ODC5MA in existing circuits?

A: The 70M-ODC5A is electrically compatible for applications where output voltage requirements do not fall below 4VDC. Both modules accept identical 5VDC input signals and switch 3A loads. Physical form factor compatibility (Mini style) supports direct mounting substitution.

Q: What is the significance of the output voltage range difference?

A: The SM-ODC5MA operates from 1VDC output minimum, while the 70M-ODC5A operates from 4VDC minimum. Applications requiring DC load switching below 4VDC cannot use the 70M-ODC5A as a substitute.

Q: How do the switching time differences affect substitution?

A: The 70M-ODC5A turns on faster (0.075ms) but turns off slower (0.75ms) compared to the SM-ODC5MA. Systems dependent on rapid turn-off response must evaluate whether the 0.75ms turn-off time meets application requirements.

Q: What is the packaging difference between these parts?

A: The SM-ODC5MA is supplied in standard packaging format, while the 70M-ODC5A is supplied in bulk packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical compatibility.

Q: Are there compliance differences between these modules?

A: Both modules are REACH Unaffected and carry MSL 1 (Unlimited) ratings. The 70M-ODC5A is RoHS non-compliant, which may restrict use in applications subject to RoHS directives.
