Key Parameters

Substitute Part Grouping Explanation

Substitution for the Weidmüller 9101103200 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Breaker Type: Thermal Magnetic
• Current Rating: 800mA (parametric equivalent) or 1.22A (similar, higher capacity)
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Mounting Type: DIN Rail
• Actuator Type: Push to Reset
• Number of Poles: 1

Substitute Categories:

Parametric Equivalent: Weidmüller 9101103500 matches all electrical and mechanical parameters identically to the main part, with the advantage of active product status and RoHS compliance.

Similar Substitute: Phoenix Contact 5531008 provides functional equivalence with a higher current rating of 1.22A while maintaining identical voltage ratings, mounting configuration, and actuation method. This part is suitable for applications where the higher current capacity does not create system conflicts.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The Weidmüller 9101103500 is the primary substitute. It maintains identical electrical specifications and mechanical form factor while offering active product status and RoHS compliance. This part is suitable for all applications currently using the 9101103200 without circuit redesign.

For Higher Current Capacity Applications: The Phoenix Contact 5531008 provides a viable alternative when system requirements permit a higher current rating of 1.22A. This part maintains voltage ratings, mounting configuration, and actuation method. Selection of this part requires confirmation that the higher current rating does not conflict with circuit protection strategy or component ratings.

Compliance Considerations: The Weidmüller 9101103500 carries the same regulatory approvals as the main part (CSA C22.2 No 235, UL1077, VDE). The Phoenix Contact 5531008 approval status is not specified in available data and should be verified against system certification requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 9101103500 be used as a direct replacement for the 9101103200?

A: Yes. The 9101103500 is a parametric equivalent with identical current rating (800mA), voltage ratings (250V AC, 80V DC), mounting type (DIN Rail), and actuation method (Push to Reset). It carries the same regulatory approvals and is suitable for direct substitution.

Q: What is the difference between the Weidmüller 9101103500 and the Phoenix Contact 5531008?

A: The primary difference is current rating. The Weidmüller 9101103500 maintains the original 800mA specification, while the Phoenix Contact 5531008 is rated for 1.22A. Both share identical voltage ratings, mounting configuration, and actuation type. The Phoenix Contact part is suitable only if the higher current rating is compatible with circuit design.

Q: Why is the original part obsolete?

A: The Weidmüller 9101103200 is classified as obsolete, indicating it is no longer in active production. The Weidmüller 9101103500 represents the current production equivalent within the same manufacturer's product line.

Q: Are there packaging differences between these parts?

A: The Weidmüller 9101103200 and 9101103500 are specified with standard packaging. The Phoenix Contact 5531008 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What regulatory approvals apply to each part?

A: The Weidmüller 9101103200 and 9101103500 both carry CSA C22.2 No 235, UL1077, and VDE approvals. The Phoenix Contact 5531008 approval status is not specified in available documentation and should be confirmed against system requirements.

Q: Can the Phoenix Contact 5531008 be used in all applications where the 9101103200 is currently installed?

A: The Phoenix Contact 5531008 can be used only in applications where the higher current rating (1.22A versus 800mA) does not create circuit protection conflicts or exceed component ratings. Electrical compatibility requires verification of circuit design parameters.
