Weidmüller 992109 General Purpose Relay SPST 24V 8A - Equivalent & Substitute Parts

Part Overview

The Weidmüller 992109 is a general purpose relay with SPST-NO (1 Form A) contact configuration, designed for 24VAC/DC coil operation and rated for 8A switching capacity at 250VAC maximum. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new design implementations where legacy component replacement is required.

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 992109 is determined by the following critical parameters:

• Mounting Type: DIN Rail (required match)
• Coil Voltage: 24VAC/DC (required match)
• Contact Form: SPST-NO (1 Form A) (required match)
• Termination Style: Screw Terminal (required match)
• Contact Rating (Current): Minimum 8A (equal or greater)
• Switching Voltage: Minimum 250VAC (equal or greater)
• Coil Type: Non Latching (required match)

The Phoenix Contact 2982236 meets all mandatory substitution criteria. While the contact rating is reduced to 6A, this represents a design trade-off in the substitute part and must be evaluated against specific application current requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2982236 is the identified equivalent substitute for the Weidmüller 992109. Selection of this substitute is supported by the following factors:

• Product Status: The Phoenix Contact 2982236 is classified as Active, ensuring ongoing availability and supply chain continuity compared to the obsolete Weidmüller 992109.
• Compliance: The Phoenix Contact 2982236 is RoHS3 Compliant and REACH Affected, meeting current regulatory requirements. The Weidmüller 992109 is REACH Unaffected, reflecting its legacy status.
• Functional Equivalence: Both relays share identical mounting, coil voltage, contact form, and termination specifications, enabling direct mechanical and electrical integration.
• Design Differences: The Phoenix Contact 2982236 features reduced coil current (11 mA vs. 26 mA) and includes a lighted indicator, representing design improvements in the substitute. The contact rating reduction from 8A to 6A must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2982236 directly replace the Weidmüller 992109 in all applications?

A: Direct replacement is possible for applications where the load current does not exceed 6A. The Phoenix Contact 2982236 is rated for 6A maximum continuous current, compared to the original 8A rating. Applications requiring the full 8A capacity require alternative solutions or circuit redesign.

Q: What are the physical mounting differences between these relays?

A: Both relays use DIN Rail mounting with screw terminal connections. Physical dimensions and socket compatibility should be verified against the specific installation enclosure and existing socket infrastructure.

Q: Are there compliance or certification differences between the two parts?

A: The Phoenix Contact 2982236 is RoHS3 Compliant and REACH Affected, reflecting current regulatory standards. The Weidmüller 992109 is REACH Unaffected, indicating its classification as a legacy component. Both carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the significance of the coil current difference (26 mA vs. 11 mA)?

A: The reduced coil current in the Phoenix Contact 2982236 indicates improved efficiency and lower power consumption during operation. This difference may affect control circuit design, particularly in applications with limited power supply capacity or where thermal management is critical.

Q: Does the lighted indicator feature on the Phoenix Contact 2982236 affect substitution compatibility?

A: The lighted indicator is an additional feature that does not prevent substitution. It provides operational status visibility, which may be beneficial in panel-mounted applications. The indicator does not interfere with the relay's core switching function.

Q: What packaging considerations apply to these parts?

A: The Weidmüller 992109 is supplied in standard packaging. The Phoenix Contact 2982236 is supplied in Bulk packaging. Procurement quantities and storage requirements should be adjusted accordingly.
