Substitute Part Grouping Explanation

The Phoenix Contact 2981431 is identified as a direct substitute for the 2981253. Substitution validity is determined by the following criteria:

Manufacturer Continuity: Both parts are manufactured by Phoenix Contact, ensuring design philosophy and quality standards alignment.

Product Category: Both components function as safety relays, maintaining the same functional role within control circuits.

Channel and Contact Configuration: The 2981431 provides 3PST-NO (3 Form A) contact configuration, representing an expansion from the 1-2 channel specification of the original part. This expanded contact arrangement supports equivalent or enhanced switching capability.

Compliance and Certification: The substitute part maintains RoHS3 compliance (exceeding the original RoHS requirement) and carries identical ECCN classification (EAR99), ensuring regulatory and export compatibility.

Product Status: The 2981431 is classified as Active, providing long-term availability and supply chain stability compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

Compliance Verification: The 2981431 substitute maintains or exceeds the compliance profile of the original 2981253. RoHS3 compliance represents an advancement over the baseline RoHS requirement. Both parts carry EAR99 classification, confirming export control compatibility.

Supply Chain Continuity: Selection of the 2981431 ensures access to an active product with documented inventory availability (923 units in stock). This addresses the supply risk associated with the obsolete 2981253 status.

Manufacturer Consistency: Remaining within the Phoenix Contact product family preserves design integration, support documentation, and quality assurance protocols established for the original component.

Regulatory Alignment: REACH compliance status of the 2981431 confirms adherence to current European chemical substance regulations, supporting long-term regulatory compliance in applications subject to REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2981431 directly replace the 2981253 in existing installations?

A: The 2981431 is identified as a direct substitute based on manufacturer continuity, product category alignment, and compliance equivalence. The expanded 3PST-NO contact configuration of the 2981431 provides equivalent or enhanced switching capability compared to the 1-2 channel specification of the original part. Circuit integration requirements must be evaluated based on specific application contact and voltage demands.

Q: What is the significance of the product status change from Obsolete to Active?

A: The transition from Obsolete (2981253) to Active (2981431) status ensures long-term component availability, ongoing manufacturing support, and supply chain stability. Active products receive continued quality assurance and documentation updates, reducing risk in maintenance and redesign scenarios.

Q: Are there packaging differences between the original and substitute parts?

A: The 2981253 is specified with dash packaging notation, while the 2981431 is supplied in Bulk packaging. The 2981431 specifies DIN Rail mounting, providing standardized installation compatibility with industrial control enclosures.

Q: How do the electrical specifications of the 2981431 compare to the original part?

A: The 2981431 provides documented electrical specifications including 24VDC coil voltage, 6A contact rating, 250VAC/250VDC maximum switching voltage, 70ms operate time, and 20ms release time. These specifications define the operational envelope for the substitute component. Original part specifications are not provided in available documentation.

Q: What compliance certifications apply to the substitute part?

A: The 2981431 carries ROHS3 compliance, EAR99 export classification, and REACH Affected status. These certifications confirm adherence to current environmental, export control, and chemical substance regulations applicable to electronic components.

Q: Does the substitute part maintain the same ECCN classification?

A: Yes, both the 2981253 and 2981431 carry EAR99 ECCN classification, confirming equivalent export control treatment and regulatory alignment for international distribution.
