Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0914400 is determined by strict equivalence across the following critical parameters:

• Current Rating: 500mA
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 65V
• Breaker Type: Thermal Magnetic
• Number of Poles: 1
• Mounting Type: DIN Rail
• Actuator Type: Lever
• Series: TMC
• RoHS Compliance: Required

All substitute parts listed below match these parameters exactly, confirming direct functional and mechanical interchangeability for the 0914400 in applications requiring a single-pole thermal magnetic DIN rail circuit breaker with the specified voltage and current ratings.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0914400, 0914044, and 0914581—are active Phoenix Contact products with identical electrical and mechanical specifications. Each maintains RoHS compliance and is suitable for direct substitution in DIN rail-mounted applications requiring a 500mA thermal magnetic circuit breaker at 250V AC / 65V DC.

Selection between these equivalents may be based on inventory availability, lead time, or procurement source. The 0914400 currently maintains 1082 units in stock, while 0914044 has 820 units and 0914581 has 716 units available. All parts are supplied in bulk packaging and carry the same ECCN classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can 0914044 or 0914581 be used as direct replacements for 0914400?

A: Yes. Both parts are parametric equivalents with identical current ratings (500mA), voltage ratings (250V AC / 65V DC), breaker type (thermal magnetic), pole configuration (1-pole), mounting method (DIN rail), and actuator type (lever). They are interchangeable for applications requiring these specifications.

Q: What determines if a circuit breaker is a valid substitute for the 0914400?

A: A substitute must match all critical parameters: 500mA current rating, 250V AC and 65V DC voltage ratings, thermal magnetic operation, single-pole configuration, DIN rail mounting, and lever actuation. Deviation in any of these parameters disqualifies a part from substitution.

Q: Are there differences in packaging or compliance between these parts?

A: All three parts are supplied in bulk packaging and are RoHS compliant. They share the same ECCN classification (EAR99). Minor differences exist in HTSUS codes (0914400: 8536.20.0040; 0914044 and 0914581: 8536.20.0020), which reflect tariff classification but do not affect functional equivalence.

Q: Which part should I select if all three are available?

A: Selection should be based on procurement requirements, inventory availability, and lead time. The 0914400 has the highest current stock level (1082 units), while 0914044 and 0914581 offer alternative sourcing options. All three are active products suitable for new designs and replacements.

Q: Do these parts require any special handling or installation considerations?

A: All parts are DIN rail-mounted circuit breakers with lever actuation. Installation follows standard DIN rail mounting procedures. No special handling beyond standard electronic component practices is required. Refer to Phoenix Contact technical documentation for specific installation guidance.
