Key Parameters

Substitute Part Grouping Explanation

Substitution of the XT424730 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Coil voltage: 230VAC
• Contact form: DPDT (2 Form C)
• Contact rating: 8 A minimum
• Switching voltage: 400VAC maximum or higher
• Coil type: Non Latching
• Contact material: Silver Nickel (AgNi)

Mechanical Equivalence Requirements:

• Mounting type: Socketable
• Termination style: Plug In

Compliance Requirements:

• RoHS3 Compliant status

The substitute part 40.52.8.230.0000 (Finder Relays, Inc.) meets all critical electrical and mechanical parameters required for direct substitution. Both relays share identical coil voltage, contact configuration, current rating, switching voltage capability, mounting type, and termination style. Both are RoHS3 compliant and utilize Silver Nickel contact material.

Parameter Comparison

Engineering Selection Recommendations

The 40.52.8.230.0000 (Finder Relays, Inc.) is a direct electrical and mechanical equivalent to the obsolete XT424730. Both relays satisfy identical coil voltage, contact configuration, current rating, and switching voltage specifications. Both are socketable with plug-in termination and utilize Silver Nickel contact material.

The Finder relay carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance. The Finder relay operates across an extended temperature range (-40°C to 85°C) compared to the XT424730 (-40°C to 70°C), providing broader environmental capability.

The Finder relay demonstrates faster switching characteristics with reduced operate time (7 ms versus 9 ms) and release time (3 ms versus 6 ms), along with lower coil current (5 mA versus 7.1 mA). These performance differences do not preclude substitution and may provide operational advantages in applications where faster response is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 40.52.8.230.0000 directly replace the XT424730 in existing applications?

A: Yes. Both relays share identical coil voltage (230VAC), contact form (DPDT), current rating (8A), switching voltage (400VAC maximum), mounting type (socketable), and termination style (plug-in). Electrical and mechanical compatibility is established.

Q: What are the key differences between these two relays?

A: The primary differences are product status (XT424730 is obsolete; 40.52.8.230.0000 is active), operating temperature range (XT424730: -40°C to 70°C; Finder: -40°C to 85°C), switching speed (Finder operates faster), and coil current (Finder requires less current). These differences do not affect substitution compatibility.

Q: Are both relays RoHS3 compliant?

A: Yes. Both the XT424730 and 40.52.8.230.0000 are ROHS3 compliant.

Q: What is the significance of the socketable mounting type?

A: Socketable mounting indicates both relays are designed for plug-in installation into a relay socket base. This mechanical compatibility ensures physical interchangeability in existing socket installations.

Q: Does the lower coil current of the 40.52.8.230.0000 affect circuit design?

A: The Finder relay requires 5 mA coil current compared to 7.1 mA for the XT424730. This lower current demand may reduce power consumption in the control circuit but does not prevent substitution. Existing control circuits designed for the XT424730 will operate the Finder relay without modification.

Q: What contact material is used in both relays?

A: Both relays utilize Silver Nickel (AgNi) contact material, ensuring consistent electrical performance and contact reliability.
