Weidmüller 9101003200 Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Weidmüller 9101003200 is a single-pole thermal magnetic circuit breaker rated for 500mA at 250V AC and 80V DC, designed for DIN rail mounting with push-to-reset actuation. This component is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and replacement applications. Active equivalent models are available from both the original manufacturer and alternative suppliers that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for this circuit breaker is determined by strict equivalence across the following critical parameters:

• Current Rating: 500mA (exact match required)
• Voltage Rating AC: 250V (exact match required)
• Voltage Rating DC: 80V (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Actuator Type: Push to Reset (exact match required)
• Number of Poles: 1 (exact match required)

Two substitute parts meet these criteria. The Weidmüller 7940125372 is a parametric equivalent from the original manufacturer in the same CB4200 series with active product status. The Phoenix Contact 5650106 is a similar manufacturer part from an alternative supplier, also meeting all electrical and mechanical parameters while belonging to the TMC42 series.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring replacement of the obsolete Weidmüller 9101003200, the Weidmüller 7940125372 is the primary substitute. This part maintains identical electrical specifications, belongs to the same CB4200 series, carries active product status, and holds the same regulatory approvals (CSA C22.2 No 235, UL1077, VDE). The 7940125372 is additionally RoHS Compliant and remains REACH Unaffected, supporting modern supply chain compliance requirements.

The Phoenix Contact 5650106 serves as an alternative substitute when Weidmüller parts are unavailable. It matches all critical electrical and mechanical parameters and maintains active product status. However, this part is REACH Affected and belongs to a different series (TMC42). Selection of the Phoenix Contact part should account for supply chain and regulatory documentation requirements specific to your application.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 7940125372 be used as a direct replacement for the 9101003200?

A: Yes. Both parts are Weidmüller CB4200 series circuit breakers with identical current ratings (500mA), voltage ratings (250V AC, 80V DC), mounting type (DIN Rail), breaker type (Thermal Magnetic), and actuator type (Push to Reset). The 7940125372 is the active equivalent with the same regulatory approvals.

Q: What is the difference between a parametric equivalent and a similar manufacturer part?

A: A parametric equivalent (7940125372) is from the same manufacturer in the same product series with identical specifications. A similar manufacturer part (5650106) meets the same electrical and mechanical requirements but originates from a different manufacturer and series. Both are functionally interchangeable based on the specified parameters.

Q: Are there packaging differences between these parts?

A: The main part 9101003200 is listed with packaging designation "-". Both substitute parts are supplied in Bulk packaging. Verify packaging requirements for your procurement process.

Q: Does the Phoenix Contact 5650106 have the same regulatory approvals?

A: The approval agencies for the Phoenix Contact 5650106 are not specified in the available data. The Weidmüller 7940125372 carries the same approvals as the original part (CSA C22.2 No 235, UL1077, VDE). Confirm regulatory compliance documentation with Phoenix Contact if required for your application.

Q: What is the significance of REACH status differences?

A: The main part and Weidmüller substitute are REACH Unaffected, while the Phoenix Contact part is REACH Affected. This distinction impacts supply chain documentation and regulatory compliance in certain markets. Select based on your application's geographic and regulatory requirements.
