PT581024 General Purpose Relay 4PDT 24VDC Equivalent & Substitute Parts

Part Overview

The PT581024 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, designed for through-hole mounting applications. This 4PDT (4 Form C) relay operates on a 24VDC coil with a 6A contact rating and supports switching voltages up to 240VAC maximum. The relay features a mechanical indicator and test button for operational verification. The part is currently active in production with 1106 pieces available in new original stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component replacement, inventory management, or design flexibility while maintaining identical functional performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PT581024 are identified based on strict electrical and mechanical parameter equivalence. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Coil Voltage: 24VDC
• Contact Form: 4PDT (4 Form C)
• Contact Rating (Current): 6 A
• Switching Voltage (Max): 240VAC
• Coil Current: 30.8 mA
• Coil Type: Non Latching
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -40°C ~ 70°C
• Contact Material: Silver Nickel (AgNi)
• Coil Resistance: 777 Ohms

The PT571024 is identified as a parametric equivalent substitute because it maintains identical values across all critical electrical and mechanical parameters. Both parts belong to the TE Connectivity Potter & Brumfield Relays product line and share the same functional specifications, enabling direct substitution in circuit applications.

Parameter Comparison
