Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 8556060000 is determined by the following critical parameters:

• Contact Configuration: SPDT (1 Form C) contact form is mandatory for functional equivalence
• Current Rating: 6A minimum contact rating required
• Switching Voltage: 250VAC maximum switching capability required
• Coil Voltage Compatibility: 60V coil operation (DC or AC/DC dual rated acceptable)
• Mounting Standard: DIN rail mounting required
• Termination: Screw terminal connection required
• Coil Type: Non-latching operation required
• Physical Features: Lighted indicator and socket inclusion preferred for form-fit compatibility

The substitute part Weidmüller 1122800000 meets all critical substitution criteria while offering enhanced specifications in coil voltage range (60VAC/DC vs. 60VDC only) and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1122800000 is the direct substitute for the obsolete 8556060000. Selection is based on the following engineering factors:

• Product Status: The substitute part 1122800000 is active and currently in production, ensuring long-term availability and supply chain continuity
• Functional Equivalence: Both parts maintain identical SPDT contact configuration, 6A current rating, and DIN rail mounting, ensuring direct replacement capability
• Enhanced Specifications: The substitute offers expanded coil voltage compatibility (60VAC/DC vs. 60VDC only), wider operating temperature range (-40°C to 60°C vs. -25°C to 50°C), and dual switching voltage support (250VAC and 250VDC)
• Compliance: Both parts carry identical REACH and ECCN classifications, maintaining regulatory compliance across applications
• Contact Material Difference: The substitute uses Silver Nickel (AgNi) contacts versus Silver Tin Oxide (AgSnO) in the original, both suitable for general purpose relay applications at the specified ratings

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1122800000 directly replace the 8556060000 in existing installations?

A: Yes. Both relays share identical contact configuration (SPDT), current rating (6A), switching voltage capability (250VAC), mounting type (DIN rail), and termination style (screw terminal). The substitute is form-fit compatible and functionally equivalent.

Q: What is the key difference between the coil specifications?

A: The original 8556060000 operates on 60VDC only. The substitute 1122800000 operates on 60VAC/DC, providing flexibility for both AC and DC coil supply applications. In 60VDC applications, both perform identically.

Q: Does the operating temperature range difference affect substitution?

A: The substitute 1122800000 offers a wider operating temperature range (-40°C to 60°C) compared to the original (-25°C to 50°C). This represents an enhancement and does not restrict substitution in applications within the original temperature range.

Q: Are there packaging differences between these parts?

A: The original 8556060000 is listed as obsolete with packaging designation "-". The substitute 1122800000 is supplied in bulk packaging and is currently in active production.

Q: What contact material is used in each relay?

A: The 8556060000 uses Silver Tin Oxide (AgSnO) contacts. The 1122800000 uses Silver Nickel (AgNi) contacts. Both materials are suitable for general purpose relay applications at 6A and 250VAC switching ratings.

Q: Is the lighted indicator and socket included in the substitute part?

A: Yes. Both the original and substitute parts include a lighted indicator and socket as standard features, ensuring compatibility with existing mounting and indication requirements.
