Weidmüller 8710270000 Equivalent & Substitute Parts

Part Overview

The Weidmüller 8710270000 is a solid state circuit breaker rated for 5A at 24VDC, designed for DIN rail mounting with slide switch actuation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new design implementations where this specific model is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 8710270000 is determined by the following critical parameters:

• Breaker Type: Solid State (functional equivalence requirement)
• Mounting Type: DIN Rail (mechanical compatibility requirement)
• Actuator Type: Slide Switch (operational interface requirement)
• Voltage Rating: 24VDC (electrical compatibility requirement)
• Current Rating: 5A nominal or higher (protective function requirement)

The Phoenix Contact 0903028 qualifies as a substitute based on these parameters. While the current rating is specified as 6A (exceeding the 5A requirement), solid state circuit breakers with higher current ratings remain compatible for applications requiring 5A protection, as the device will provide equivalent or enhanced protective capability within the same voltage and mounting framework.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 0903028 is the identified substitute for the obsolete Weidmüller 8710270000. Selection is based on the following factors:

• Product Status: The Phoenix Contact 0903028 is classified as Active, ensuring ongoing availability and support compared to the obsolete Weidmüller component.
• Functional Equivalence: Both devices are solid state circuit breakers with identical voltage ratings (24VDC), mounting configuration (DIN Rail), and actuation method (Slide Switch).
• Current Rating: The 6A rating of the Phoenix Contact device exceeds the 5A requirement, providing equivalent protective function for the specified application.
• Compliance: The Phoenix Contact 0903028 is RoHS3 Compliant, meeting current environmental and safety standards. The REACH Affected status indicates regulatory compliance within applicable jurisdictions.
• Availability: 803 units are documented as in stock, supporting immediate procurement for replacement or new installations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 0903028 directly replace the Weidmüller 8710270000 in existing installations?

A: Yes. Both devices share identical mounting type (DIN Rail), voltage rating (24VDC), breaker type (Solid State), and actuator type (Slide Switch). The 6A current rating of the Phoenix Contact device is compatible with applications requiring 5A protection.

Q: What is the significance of the current rating difference (5A vs. 6A)?

A: The Phoenix Contact 0903028 is rated for 6A, which exceeds the 5A specification of the Weidmüller device. In solid state circuit breaker applications, a higher current rating does not compromise protection; it indicates the device can handle equal or greater load capacity while maintaining the same protective characteristics.

Q: Are there packaging differences between these components?

A: The Weidmüller 8710270000 is specified with "-" packaging notation, while the Phoenix Contact 0903028 is supplied in Bulk packaging. Both are suitable for DIN rail installation and do not require special handling beyond standard component storage practices.

Q: What is the impact of the REACH status difference?

A: The Weidmüller component is REACH Unaffected, while the Phoenix Contact component is REACH Affected. This indicates the Phoenix Contact device is subject to REACH regulatory requirements. Both statuses are compliant within their respective regulatory frameworks and do not prevent substitution.

Q: Is the RoHS3 compliance of the Phoenix Contact device relevant for substitution?

A: Yes. RoHS3 Compliance of the Phoenix Contact 0903028 indicates the device meets current environmental standards for restricted substances. This is advantageous for new designs and long-term system reliability compared to the obsolete Weidmüller component.
