Phoenix Contact 2967552 SSR Relay SPST-NO 100mA 3-48V Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2967552 is a solid-state relay (SSR) module configured as SPST-NO (Single Pole Single Throw - Normally Open) with a 1 Form A circuit. This component is designed for DC load switching applications with input control voltage of 120VAC/DC and output load voltage range of 3V to 48V at 100mA maximum current. The module features spring terminal connections and DIN rail mounting capability.

The 2967552 is classified as obsolete. Locating an active equivalent part is necessary to ensure continued availability, supply chain reliability, and access to current manufacturing support and documentation.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2900355 qualifies as a direct substitute for the 2967552 based on the following critical parameters:

• Circuit Configuration: Both parts implement SPST-NO (1 Form A) switching logic
• Output Type: Both provide DC output switching
• Input Voltage: Both accept 120VAC/DC control voltage
• Load Voltage Range: Both support 3V to 48V output voltage
• Load Current: Both are rated for 100mA maximum current
• Mounting Type: Both use DIN rail mounting
• Termination Style: Both employ spring terminal connections
• Package Type: Both are module packages
• RoHS Compliance: Both meet RoHS requirements

The primary difference is product status: the 2967552 is obsolete while the 2900355 is active. The 2900355 belongs to the PLC-OPT series (versus PLC-OSP for the original part) and carries updated moisture sensitivity classification (MSL 1 - Unlimited versus Not Applicable).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900355 is the appropriate substitute for the obsolete 2967552. Both parts maintain identical electrical and mechanical specifications across all critical switching parameters. The 2900355 is currently in active production status, ensuring availability and ongoing manufacturer support.

Selection of the 2900355 is supported by:

• Full electrical parameter equivalence (input voltage, output voltage range, load current, circuit configuration)
• Identical mechanical interface (DIN rail mounting, spring terminals, module package)
• Active product status with current manufacturing and supply chain support
• RoHS compliance certification maintained across both parts
• Same manufacturer (Phoenix Contact) ensuring design continuity and documentation compatibility

Frequently Asked Questions (FAQ)

Q: Can the 2900355 be used as a direct replacement for the 2967552 in existing applications?

A: Yes. The 2900355 provides identical electrical switching characteristics (SPST-NO, 100mA at 3-48V DC output, 120VAC/DC input) and mechanical interface (DIN rail mount, spring terminals). No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The 2967552 is classified as obsolete. The 2900355 is an active equivalent part from the same manufacturer with identical functional specifications.

Q: Are there differences in packaging or delivery format?

A: The 2967552 was supplied with unspecified packaging, while the 2900355 is supplied in bulk packaging. This does not affect component functionality or electrical performance.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant. The 2900355 includes updated moisture sensitivity level classification (MSL 1 - Unlimited) compared to the original part specification.

Q: Are the series designations (PLC-OSP vs. PLC-OPT) significant for substitution?

A: Series designations reflect product line evolution within Phoenix Contact's portfolio. The functional and electrical specifications remain equivalent. The PLC-OPT series (2900355) represents the current active product line.
