The substitute part RY531024 maintains functional compatibility through identical specifications in the following critical parameters:

Electrical Equivalence Criteria:

• Coil voltage: 24VDC
• Contact form: SPST-NO (1 Form A)
• Contact current rating: 8 A
• Switching voltage maximum: 400VAC
• Coil current: 10.2 mA
• Coil type: Non Latching
• Coil resistance: 2.35 kOhms
• Must operate voltage: 16.8 VDC
• Must release voltage: 2.4 VDC
• Operate time: 9 ms
• Release time: 5 ms
• Operating temperature range: -40°C to 70°C

Mechanical Equivalence Criteria:

• Mounting type: Through Hole
• Termination style: PC Pin
• Seal rating: Sealed - Flux Protection

The substitute part differs in contact material composition (silver nickel versus silver cadmium oxide) and product status (active versus obsolete), but maintains all functional electrical and mechanical parameters required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The RY531024 is the direct substitute for the obsolete 7-1415507-1 based on complete electrical and mechanical parameter equivalence. Selection of RY531024 is supported by the following factors:

Product Status: RY531024 is classified as active, ensuring ongoing availability and supply chain continuity. The 7-1415507-1 is obsolete and no longer manufactured.

Regulatory Compliance: RY531024 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for new designs and production. These certifications are not specified for the 7-1415507-1.

Functional Equivalence: All electrical parameters, mechanical specifications, and performance characteristics are identical between the two parts, enabling direct substitution without circuit redesign or application modification.

Contact Material Difference: The substitute part uses silver nickel (AgNi) contact material instead of silver cadmium oxide (AgCdO). Both materials are suitable for general purpose relay applications with identical current and voltage ratings. The silver nickel composition in RY531024 aligns with modern manufacturing standards and environmental compliance requirements.
