Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2801259 is determined by the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Phoenix Contact (same manufacturer ensures design compatibility)
• Series: PT (maintains product line consistency)
• Category: Transient Voltage Suppressors (TVS)
• Form Factor: Base + Module (mechanical and electrical interface compatibility)
• Number of Poles: 1 (circuit configuration match)
• Mounting Type: DIN Rail (installation compatibility)
• Voltage - Continuous Operating (Max) (MCOV): 4VAC, 6VDC (electrical rating compatibility)
• Current - Discharge (Nom) (8/20µS): 10 kA (nominal performance specification)
• Current - Discharge (Max) (8/20µS): 20 kA (maximum performance specification)
• RoHS Status: RoHS Compliant (regulatory compliance)
• Approval Agency: UL (certification requirement)

The substitute part 2801260 maintains all critical electrical and mechanical parameters required for direct substitution. Variations in protection level voltage and operating temperature range do not preclude substitution when the primary electrical characteristics remain within acceptable tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2801260 is the direct substitute for the obsolete 2801259. Both components maintain identical electrical performance specifications for continuous operating voltage, nominal discharge current, and maximum discharge current. Both parts carry RoHS Compliance certification and UL approval, ensuring regulatory and safety standard adherence.

The 2801260 is classified as Active product status, providing assured long-term availability and supply chain continuity compared to the Obsolete 2801259. The substitute part is suitable for direct replacement in existing designs and new implementations requiring Phoenix Contact PT series TVS protection modules.

Frequently Asked Questions (FAQ)

Q: Can the 2801260 directly replace the 2801259 in existing installations?

A: Yes. Both parts share identical electrical specifications for continuous operating voltage (4VAC, 6VDC), nominal discharge current (10 kA), and maximum discharge current (20 kA). Both are DIN Rail mounted, single-pole Base + Module configurations with UL approval and RoHS compliance. The 2801260 is the designated active substitute for the obsolete 2801259.

Q: What is the difference in protection level voltage between these parts?

A: The 2801259 provides 800V protection level, while the 2801260 provides 1.3kV protection level. Both operate within the same continuous voltage rating of 6VDC maximum. The higher protection level in the 2801260 does not affect compatibility for applications designed around the 2801259 specifications.

Q: Are there packaging differences between these parts?

A: The 2801259 is listed with unspecified packaging, while the 2801260 is supplied in Bulk packaging. Both parts maintain identical mechanical form factors and DIN Rail mounting interfaces.

Q: What is the operating temperature difference?

A: The 2801259 operates across -40°C to 80°C, while the 2801260 operates across -40°C to 70°C. For applications requiring operation above 70°C, the original 2801259 specifications should be evaluated against system requirements.

Q: Why is the 2801259 classified as Obsolete?

A: Obsolete status indicates the part is no longer manufactured. The 2801260 is the active replacement within the Phoenix Contact PT series, providing equivalent electrical performance with assured ongoing availability.
