VAL-CP-3S-350/O Equivalent & Substitute Parts

Part Overview

The Phoenix Contact VAL-CP-3S-350/O (Manufacturer Part Number: 2881010) is a Type 2 Transient Voltage Suppressor (TVS) designed for circuit protection applications. This device is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign projects. The VAL-CP series provides transient overvoltage protection on DIN Rail-mounted installations with a maximum continuous operating voltage of 350VAC and a protection level of 1.9 kV at the 2416 test condition.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VAL-CP-3S-350/O is determined by the following critical electrical and mechanical parameters:

• Voltage Rating (MCOV): The substitute must operate at or above 350VAC continuous operating voltage to maintain equivalent protection in the same circuit configuration.
• Discharge Current Capability: The substitute must handle nominal discharge currents of at least 20 kA (8/20µS) and maximum discharge currents of at least 40 kA to provide equivalent transient suppression.
• Short Circuit Rating (SCRR): The substitute must maintain a short circuit rating of at least 25 kA for equivalent fault tolerance.
• Protection Level (VP): The substitute protection level should be within acceptable limits for the protected circuit; the original device specifies 1.9 kV at the 2416 test condition.
• Mounting and Form Factor: The substitute must support DIN Rail mounting with Base + Module configuration to ensure mechanical compatibility.
• Operating Temperature: The substitute must support the -40°C ~ 80°C operating range.
• Type Classification: Type 2 classification indicates the suppression mechanism and response characteristics required for this application.

The Phoenix Contact VAL-MS-T1/T2 335/12.5/3+0 (Manufacturer Part Number: 2800189) is identified as a substitute based on compatibility across these parameters, with the understanding that certain electrical characteristics differ within acceptable engineering tolerances for TVS device substitution.

Parameter Comparison

Engineering Selection Recommendations

The VAL-CP-3S-350/O is obsolete and no longer in active production. The VAL-MS-T1/T2 335/12.5/3+0 (2800189) is an active product from the same manufacturer with equivalent mechanical compatibility and environmental specifications.

Compliance and Certifications: The substitute part carries multiple approval agencies (CB, cUR, cURus, EAC, UR) compared to the original part, providing broader regulatory acceptance. Both devices are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity ratings.

Electrical Characteristics: The substitute operates at 335VAC MCOV versus the original 350VAC. The protection level differs at 1.2 kV versus 1.9 kV. The nominal discharge current is lower at 12.5 kA versus 20 kA, while maximum discharge current is higher at 50 kA versus 40 kA. These differences must be evaluated against the specific circuit protection requirements of the application.

Availability and Status: The substitute part is currently in active production with 1092 units in stock, whereas the original obsolete part has limited availability (957 units noted as new original stock).

Frequently Asked Questions (FAQ)

Q: Can the VAL-MS-T1/T2 335/12.5/3+0 directly replace the VAL-CP-3S-350/O in all applications?

A: Both devices share the same DIN Rail mounting type, Base + Module form factor, single pole configuration, and operating temperature range. However, the electrical characteristics differ. The substitute has a lower MCOV (335VAC vs. 350VAC) and lower protection level (1.2 kV vs. 1.9 kV). Application-specific circuit analysis is required to confirm compatibility.

Q: What is the significance of the Type 1 and Type 2 designation on the substitute part?

A: The substitute part is rated for both Type 1 and Type 2 operation, providing operational flexibility. The original part is Type 2 only. This broader capability in the substitute does not prevent its use in Type 2 applications.

Q: How do the discharge current ratings affect substitution?

A: The original part specifies 20 kA nominal and 40 kA maximum discharge current (8/20µS). The substitute specifies 12.5 kA nominal and 50 kA maximum. The lower nominal rating may affect response characteristics in moderate transient events, while the higher maximum rating provides greater fault tolerance. Circuit protection requirements determine acceptability.

Q: Are there packaging differences between these parts?

A: The original part packaging is listed as unspecified (-), while the substitute is supplied in Bulk packaging. Both use identical DIN Rail mounting and Base + Module form factors, so mechanical installation is equivalent.

Q: What regulatory approvals does the substitute carry?

A: The substitute part carries CB, cUR, cURus, EAC, and UR approvals, providing compliance for North American, European, and international markets. The original part approval agencies are not specified in the available data.
