Weidmüller 8530681001 General Purpose Relay DPDT 230VAC - Equivalent & Substitute Parts

Part Overview

The Weidmüller 8530681001 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 10A at 230VAC coil voltage, and designed for DIN rail mounting. This relay features a lighted indicator and socket inclusion for modular installation. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in ongoing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 8530681001 is determined by the following critical parameters:

• Contact Form: DPDT (2 Form C) configuration must be maintained for circuit switching functionality
• Coil Voltage: 230VAC primary operating voltage
• Mounting Type: DIN rail compatibility for panel integration
• Contact Rating: Minimum 8A current capacity (original part rated 10A)
• Switching Voltage: 250VAC maximum rating
• Coil Type: Non-latching operation
• Termination Style: Screw terminal connection
• Features: Lighted indicator and socket inclusion for modular operation

The Weidmüller 1123540000 qualifies as a functional substitute based on these parameters. While the contact rating is reduced from 10A to 8A, this represents a downrating that is acceptable in applications where the actual load current does not exceed 8A. The substitute part maintains identical contact form, DIN rail mounting, screw terminal termination, and includes the same feature set (lighted indicator and socket).

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1123540000 is the designated substitute for the obsolete Weidmüller 8530681001. Selection of this substitute is supported by the following factors:

• Product Status: The substitute part (1123540000) is active and currently in production, ensuring long-term availability and supply chain continuity
• Compliance: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring regulatory equivalence
• Functional Compatibility: Identical contact form (DPDT), mounting type (DIN rail), termination style (screw terminal), and feature set (lighted indicator, socket included) ensure direct mechanical and electrical compatibility
• Enhanced Capability: The substitute part supports both 230VAC and 230VDC coil operation, providing operational flexibility beyond the original part specification
• Temperature Range Extension: The substitute part operates across -40°C to 60°C, extending the upper temperature limit by 10°C compared to the original part

The primary consideration for substitution is the reduction in contact rating from 10A to 8A. This substitution is valid only in applications where the actual load current does not exceed 8A. For applications requiring the full 10A contact rating, alternative solutions must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1123540000 be used as a direct replacement for the 8530681001 in all applications?

A: The 1123540000 is mechanically and electrically compatible with the 8530681001 for DIN rail mounting, screw terminal connection, and DPDT switching functionality. However, the contact rating is reduced from 10A to 8A. Substitution is valid only if the actual load current in the application does not exceed 8A. Applications requiring 10A contact rating require alternative component selection.

Q: What are the key differences between these two relay models?

A: The primary differences are: (1) contact rating (10A vs. 8A), (2) coil voltage flexibility (230VAC only vs. 230VAC/DC), (3) operating temperature range (-40°C to 50°C vs. -40°C to 60°C), and (4) coil resistance (32.5 kOhms vs. 57.5 kOhms). All other functional parameters, including contact form, mounting type, termination style, and features, are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99), ensuring regulatory equivalence for procurement and deployment.

Q: Does the substitute part support DC coil operation?

A: Yes. The Weidmüller 1123540000 supports both 230VAC and 230VDC coil operation, whereas the original 8530681001 is rated for 230VAC only. This provides operational flexibility for applications requiring DC control circuits.

Q: What is the impact of the different coil resistance values?

A: The substitute part has a higher coil resistance (57.5 kOhms vs. 32.5 kOhms), resulting in lower coil current (4 mA vs. 4.2 mA). This represents a minor reduction in power consumption and may affect circuit design considerations for control signal sourcing, but does not impact the relay's switching functionality.

Q: Is the packaging format a consideration for substitution?

A: The original part is packaged as individual units, while the substitute part is supplied in bulk packaging. Both are DIN rail mounted relays with identical form factors. Packaging format does not affect electrical or mechanical compatibility.
