Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact ECP 3 (0911047) is determined by the following critical parameters:

• Current Rating: 3A (exact match required)
• Voltage Rating - DC: 24V (exact match required)
• Breaker Type: Solid State (exact match required)
• Number of Poles: 1 (exact match required)
• Manufacturer: Phoenix Contact (same manufacturer preferred for design continuity)

The identified substitute part (2909904) maintains electrical equivalence across all critical parameters. The primary difference is the mounting configuration: the original part uses panel mount, while the substitute employs DIN rail mounting. This distinction affects physical installation but does not alter electrical performance or protection characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2909904 is electrically equivalent to the obsolete 0911047 across all critical protection parameters: current rating, voltage rating, pole configuration, and solid-state switching technology. Both components share identical ECCN and HTSUS classifications, confirming regulatory equivalence.

The 2909904 holds active product status with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete 0911047. The transition from panel mount to DIN rail mounting requires mechanical redesign of the installation interface but does not affect electrical performance or protection function.

Selection of the 2909904 as a substitute is supported by its active market availability, enhanced RoHS compliance level, and identical electrical specifications for 3A, 24V DC solid-state circuit protection.

Frequently Asked Questions (FAQ)

Q: Can the 2909904 directly replace the 0911047 without circuit modifications?

A: Electrical substitution is valid. The 2909904 provides identical current and voltage protection characteristics. Physical installation requires adaptation due to mounting type differences: the original uses panel mount while the substitute uses DIN rail mounting.

Q: What is the significance of the mounting type difference?

A: Mounting type affects mechanical installation only. Panel mount (0911047) installs directly into a panel cutout, while DIN rail mount (2909904) attaches to standard 35mm DIN rail. Electrical performance and protection function remain unchanged.

Q: Why is the 0911047 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 2909904 serves as the active replacement, offering equivalent electrical specifications with current manufacturing support.

Q: Are there compliance differences between the two parts?

A: Both parts comply with RoHS regulations. The 2909904 carries ROHS3 certification (enhanced compliance), while the 0911047 carries standard RoHS compliance. Both share identical ECCN (EAR99) and HTSUS (8536.20.0020) classifications.

Q: What does the actuator type difference mean?

A: The 2909904 specifies a lever actuator for manual operation, while the 0911047 does not specify an actuator type. This reflects the different mounting styles but does not affect automatic protection function.
