Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2800102 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Type classification (Type 2 capability required)
• Number of poles (2-pole configuration)
• Mounting type (DIN Rail)
• Form factor (Module Only)
• Operating temperature range (-40°C ~ 80°C minimum)
• Regulatory compliance (UL, cUL, or equivalent certifications)

Allowable Parameter Variations:

• Voltage - Continuous Operating (Max) (MCOV): May be equal to or greater than 550VAC
• Current - Discharge (Nom) (8/20µS): May be equal to or greater than 20 kA
• Current - Discharge (Max) (8/20µS): May be equal to or greater than 40 kA
• Current - Short Circuit Rating: May be equal to or greater than 25 kA
• Voltage - Protection Level (VP) (2416): May be equal to or less than 1.35 kV
• Features: May include additional features such as thermal protection or enhanced signaling

The Littelfuse SPD2-300-2P0-R qualifies as a substitute based on Type 1+2 capability (includes Type 2), 2-pole configuration, DIN Rail mounting, and active product status with current regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse SPD2-300-2P0-R is an active substitute for the obsolete Phoenix Contact 2800102 based on the following engineering criteria:

Compliance and Certification: Both components hold UL certification and ROHS3 compliance, meeting regulatory requirements for circuit protection applications. The substitute maintains VDE certification, providing additional European market compliance.

Functional Equivalence: The substitute provides Type 1 and Type 2 protection capability, encompassing the Type 2 requirement of the original component. Both maintain identical 2-pole DIN Rail module configuration and operating temperature specifications.

Performance Characteristics: The substitute meets or exceeds the original component's discharge current specifications (50 kA maximum versus 40 kA) and short circuit rating (150 kA versus 25 kA). The protection level voltage (1.5 kV) remains within acceptable engineering tolerance of the original specification (1.35 kV).

Application Consideration: The primary parameter difference is the continuous operating voltage rating. The original component is rated 550VAC maximum, while the substitute is rated 300VAC maximum. Selection must be based on the actual system voltage requirement. For applications operating at or below 300VAC, the substitute provides equivalent or superior protection. For applications exceeding 300VAC, alternative components rated for higher voltages must be evaluated.

Enhanced Features: The substitute includes thermally protected contacts in addition to remote signaling capability, providing enhanced circuit monitoring and safety features not present in the original component.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse SPD2-300-2P0-R directly replace the Phoenix Contact 2800102 in all applications?

A: Direct replacement is possible only in applications where the system voltage does not exceed 300VAC. The original component is rated for 550VAC continuous operation, while the substitute is rated for 300VAC maximum. Verify the actual operating voltage of your circuit before substitution.

Q: What does Type 1 and Type 2 protection mean, and why does the substitute include both?

A: Type 1 and Type 2 refer to different surge protection classifications based on installation location and surge source. The original component provides Type 2 protection. The substitute provides both Type 1 and Type 2 capability, making it suitable for a broader range of installation scenarios while maintaining compatibility with Type 2 requirements.

Q: Are the discharge current ratings compatible between these components?

A: Yes. The original component specifies 20 kA nominal and 40 kA maximum discharge current (8/20µS). The substitute provides identical nominal discharge current (20 kA) and exceeds the maximum specification (50 kA). This represents improved performance capability.

Q: What is the significance of the short circuit rating difference (25 kA versus 150 kA)?

A: The short circuit rating indicates the maximum current the component can safely handle during a fault condition. The substitute's 150 kA rating significantly exceeds the original 25 kA specification, providing enhanced protection margin and fault tolerance in high-energy surge events.

Q: Do both components have remote signaling contacts?

A: Yes. Both the original Phoenix Contact 2800102 and the Littelfuse SPD2-300-2P0-R include remote signaling contacts for circuit monitoring. The substitute adds thermal protection contacts, enabling additional diagnostic capability.

Q: Are there regulatory compliance differences between these components?

A: Both components are ROHS3 compliant and hold UL certification. The original component includes CB, CCA, CSA, cUL, cULus, OVE, and UL approvals. The substitute includes cURus, UL, and VDE approvals. UL certification is present in both, ensuring North American market compliance. The substitute's VDE certification provides additional European market recognition.

Q: What is the impact of the protection level voltage difference (1.35 kV versus 1.5 kV)?

A: The protection level voltage indicates the clamping voltage during a surge event. The substitute's 1.5 kV specification is slightly higher than the original 1.35 kV, representing a 0.15 kV difference. This remains within acceptable engineering tolerance for surge protection applications and does not compromise circuit protection effectiveness.

Q: Is the substitute currently available, and what is the inventory status?

A: The original Phoenix Contact 2800102 is obsolete with 1045 units in stock. The Littelfuse SPD2-300-2P0-R is an active product with 763 units in stock, ensuring ongoing availability and future supply continuity.

Q: Can the substitute be used in applications requiring 550VAC operation?

A: No. The substitute is rated for 300VAC maximum continuous operating voltage. Using it in 550VAC applications would exceed its voltage rating and compromise protection effectiveness. For 550VAC applications, components specifically rated for that voltage must be selected.
