Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSA-SS-224DM3,000 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match the following critical parameters without deviation:

• Coil voltage specification (24VDC)
• Contact form configuration (DPST-NO / 2 Form A)
• Contact current rating (3 A)
• Maximum switching voltage (240VAC, 30VDC)
• Mounting technology (Through Hole)
• Termination method (PC Pin)
• Coil electrical characteristics (22.5 mA, 1.1 kOhms)
• Switching timing parameters (20 ms operate, 10 ms release)
• Operating temperature range (-30°C ~ 60°C)
• Contact material composition (Silver Alloy)
• Environmental protection (Sealed - Flux Protection)

The OSA-SS-224DM3000 meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OSA-SS-224DM3000 serves as the active production equivalent to the obsolete OSA-SS-224DM3,000. Both parts are electrically and mechanically identical across all specified parameters, ensuring direct functional substitution in circuit applications.

The primary distinction between these parts is product status and regulatory compliance. The original OSA-SS-224DM3,000 is classified as obsolete and carries ROHS3 compliance certification. The substitute OSA-SS-224DM3000 maintains active product status from TE Connectivity and is designated as RoHS non-compliant.

For applications requiring RoHS3 compliance, the regulatory status difference must be evaluated against system requirements. Both parts share identical electrical performance, switching characteristics, and environmental specifications. The substitute part is suitable for direct replacement in existing designs and new applications where the electrical and mechanical parameters match system requirements.

Frequently Asked Questions (FAQ)

Q: Can the OSA-SS-224DM3000 directly replace the OSA-SS-224DM3,000 in existing circuits?

A: Yes. The OSA-SS-224DM3000 is a parametric equivalent with identical electrical specifications, contact ratings, coil characteristics, switching timing, and mechanical mounting. Direct substitution is supported across all specified parameters.

Q: What are the critical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching coil voltage (24VDC), contact form (DPST-NO), current rating (3A), switching voltage limits (240VAC/30VDC), mounting type (Through Hole), termination style (PC Pin), coil electrical properties (22.5 mA/1.1 kOhms), timing specifications (20 ms operate/10 ms release), temperature range (-30°C to 60°C), contact material (Silver Alloy), and seal rating (Sealed - Flux Protection).

Q: What is the difference in RoHS compliance between these parts?

A: The OSA-SS-224DM3,000 is ROHS3 compliant. The OSA-SS-224DM3000 is designated as RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this distinction in component selection.
