Engineering Selection Recommendations

The PICOD131ALULS is a direct functional and mechanical equivalent to the PICO131ALULS. Selection between these parts is determined by the following factors:

Product Status Consideration: The PICO131ALULS is classified as obsolete, while the PICOD131ALULS maintains active product status. For new designs, ongoing production, or long-term system support, the PICOD131ALULS is the appropriate selection due to its active availability and continued manufacturer support.

Compliance and Certification: The PICOD131ALULS carries ROHS3 compliance certification, providing assurance of regulatory alignment with current environmental and material restriction standards. The PICO131ALULS does not specify RoHS status. For applications requiring documented compliance with RoHS directives, the PICOD131ALULS is the suitable choice.

Packaging Configuration: The PICO131ALULS is supplied in standard packaging, while the PICOD131ALULS is supplied in bulk packaging. Packaging selection depends on procurement volume and inventory management requirements.

Electrical and Mechanical Equivalence: Both parts are identical in all critical electrical parameters (contact rating, output code, electrical life) and mechanical parameters (mounting type, actuator type, dimensions, materials, operating temperature range). Direct substitution is supported without circuit or mechanical redesign.
