Key Parameters

Substitute Part Grouping Explanation

Grouping of substitute solid state relay parts is strictly based on the following allowed parameters: relay type, mounting configuration, output type, input voltage range, load voltage range, load current rating, termination style, package style, environmental compliance, and regulatory classifications. Only parts matching or encompassing these specifications in the same package style and mounting configuration are included. The substitute 84139120N relay aligns on the basis of output type (AC, Zero Cross), load current (50 A), mounting type (chassis mount), termination style (screw terminal), package type (hockey puck), and required environmental compliance. Key parameters confirmed for substitution are: output type, voltage input range, voltage load range, load current, package/case, mounting type, and environmental certifications.

Parameter Comparison

Engineering Selection Recommendations

Both SMR2450-6 and 84139120N are listed as active, RoHS compliant, and REACH unaffected. Both are designated under ECCN code EAR99 for export classification. These certifications and compliance statuses support their selection as substitutes where regulatory, inventory, or environmental requirements must be maintained.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to select a substitute solid state relay for SMR2450-6?
A1: Compatible substitute selection requires matching output type, input voltage range, load voltage range, load current, package style, mounting type, termination style, and environmental compliance.

Q2: Can 84139120N be used as a direct substitute for SMR2450-6 regarding package and mounting?
A2: Yes, both relays utilize a hockey puck package and are designed for chassis mount applications with screw terminals.

Q3: Are there significant certification differences between SMR2450-6 and 84139120N?
A3: Both parts are RoHS compliant and REACH unaffected, maintaining equivalent environmental compliance and regulatory status.

Q4: How does the voltage range affect substitution?
A4: Substitution requires consideration of the input and load voltage ranges. 84139120N has a higher load voltage range and a slightly narrower input voltage range, which must be evaluated for system compatibility.

Q5: Are inventory and packaging differences relevant for substitution?
A5: Inventory and packaging type are not functional substitution criteria but may be considered for logistics or procurement purposes. Both parts are classified as new original and in stock in respective packaging as specified.
