Phoenix Contact 2952169 General Purpose Relay SPDT 5A 24V - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2952169 is a general purpose relay with SPDT (1 Form C) contact configuration, rated for 5A at 24VDC coil voltage. This relay is designed for DIN rail mounting with screw terminal connections and includes integrated diode and lighted indicator features. The part is currently obsolete, making identification of equivalent and substitute components essential for system maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Phoenix Contact 2952169 is determined by the following critical parameters: coil voltage (24VDC), contact form (SPDT/1 Form C), current rating (5A), mounting type (DIN Rail), and termination style (Screw Terminal). These parameters define the functional and mechanical compatibility requirements for direct replacement.

Two substitute parts are identified:

Parametric Equivalent (2949787): Matches all critical electrical and mechanical parameters of the original part, including SPDT contact form, 5A rating, 24VDC coil voltage, DIN rail mounting, and screw terminal termination. This part is currently active in production.

Similar Substitute (2905215): Differs in contact form (SPST-NO instead of SPDT), current rating (10A instead of 5A), and termination style (Spring Terminal instead of Screw Terminal). This part is suitable only when circuit requirements permit SPST-NO operation and mechanical mounting accommodates spring terminal connections.

Engineering Selection Recommendations

Primary Recommendation: Phoenix Contact 2949787

The 2949787 is the direct parametric equivalent to the obsolete 2952169. It maintains identical electrical specifications (24VDC coil, SPDT contact form, 5A rating), mechanical mounting (DIN rail with screw terminals), and operational characteristics (21 mA coil current, 9 ms operate time, 10 ms release time). The part is currently active in production with RoHS compliance certification, ensuring long-term availability and regulatory compliance for new installations and replacements.

Secondary Option: Phoenix Contact 2905215

The 2905215 is a solid-state relay substitute suitable only when circuit architecture permits SPST-NO operation (single throw, normally open) instead of SPDT (changeover) functionality. The higher current rating (10A) and spring terminal termination require mechanical and electrical circuit redesign. This part is active in production and ROHS3 compliant but introduces design modifications beyond direct replacement.

Frequently Asked Questions (FAQ)

Q: Can the 2949787 be used as a direct replacement for the 2952169?

A: Yes. The 2949787 is a parametric equivalent with identical coil voltage (24VDC), contact form (SPDT), current rating (5A), mounting type (DIN rail), and termination style (screw terminal). No circuit or mechanical modifications are required.

Q: What is the key difference between the 2952169 and 2905215?

A: The 2905215 is a solid-state relay with SPST-NO contact form (single throw, normally open), whereas the 2952169 is an electromechanical relay with SPDT contact form (changeover). SPDT provides both normally open and normally closed contacts; SPST-NO provides only normally open. The 2905215 also has a higher current rating (10A vs. 5A) and uses spring terminals instead of screw terminals.

Q: Why is the 2952169 marked as obsolete?

A: The 2952169 has been discontinued by Phoenix Contact. The 2949787 serves as the active production replacement with equivalent specifications.

Q: Are there any compliance differences between these parts?

A: The 2952169 and 2949787 are both RoHS compliant. The 2905215 is ROHS3 compliant, which represents a more recent regulatory standard. All three parts carry EAR99 ECCN classification.

Q: Can the 2905215 be used if the circuit only requires normally open contacts?

A: The 2905215 can be used in circuits requiring SPST-NO operation. However, the spring terminal connection requires mechanical redesign of the terminal block interface, and the higher current rating (10A) may introduce unnecessary cost and space considerations if only 5A capacity is needed.

Q: What is the operating temperature range for these relays?

A: The 2952169 and 2949787 both operate within -20°C to 50°C. Operating temperature specifications for the 2905215 are not provided in the available data.
