Phoenix Contact 0912019 Circuit Breaker Solid State 8A 24VDC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0912019 is a solid state circuit breaker rated for 8A at 24VDC, designed for single-pole protection applications. This component features a push-push actuator and holder mounting configuration. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new design implementations where this specific mounting style may no longer be available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0912019 is determined by the following critical parameters that must remain constant:

• Current Rating: 8A (exact match required)
• Voltage Rating - DC: 24V (exact match required)
• Breaker Type: Solid State (exact match required)
• Number of Poles: 1 (exact match required)

The Phoenix Contact 2909910 qualifies as a functional equivalent based on these core electrical parameters. While the mounting configuration differs (DIN Rail versus Holder), the electrical protection characteristics and performance envelope remain identical. This substitution is valid for applications where the mounting infrastructure can accommodate DIN Rail installation.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2909910 is the identified substitute for the obsolete 0912019 based on matching electrical specifications: 8A solid state protection at 24VDC with single-pole configuration. The 2909910 carries active product status with current manufacturing support and holds ROHS3 compliance, exceeding the RoHS Compliant rating of the original part. The substitute includes recognized safety certifications (cUL, cULus, UL) and REACH compliance documentation.

Selection of the 2909910 requires mechanical integration assessment, as the DIN Rail mounting differs from the original holder mounting. System design must accommodate this mounting configuration change. The substitute maintains electrical protection performance and regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2909910 directly replace the 0912019 in existing installations?

A: Electrical substitution is valid based on identical current rating (8A), voltage rating (24VDC), breaker type (solid state), and pole configuration (1-pole). Mechanical installation requires DIN Rail mounting capability in place of the original holder mounting. Existing holder-based installations require mechanical redesign or adapter solutions.

Q: What are the critical parameters that must match for substitution?

A: Current rating (8A), DC voltage rating (24V), breaker type (solid state), and number of poles (1) must remain unchanged. These parameters define the protection envelope and system compatibility.

Q: Does the 2909910 meet the same regulatory requirements as the 0912019?

A: The 2909910 exceeds the original compliance profile. It holds ROHS3 Compliant status (versus RoHS Compliant) and includes cUL, cULus, and UL certifications. REACH compliance documentation is available for the substitute.

Q: Why is the 0912019 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 2909910 represents the current Phoenix Contact offering for this electrical specification class, with active manufacturing and distribution support.

Q: Are there inventory considerations for this substitution?

A: The 0912019 maintains 1038 pieces in new original stock. The 2909910 has 707 pieces available in bulk packaging. Both parts are currently available through distribution channels.
