Substitute Part Grouping Explanation

Substitution of the 1393224-3 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Coil voltage: 9VDC
• Contact form: SPST-NO (1 Form A)
• Contact current rating: 8 A
• Switching voltage: 400VAC maximum
• Coil current: 28.1 mA
• Coil resistance: 320 Ohms
• Must operate voltage: 6.3 VDC
• Must release voltage: 0.9 VDC
• Operate time: 9 ms
• Release time: 5 ms

Mechanical Equivalence Criteria:

• Mounting type: Through Hole
• Termination style: PC Pin
• Seal rating: Sealed - Fully
• Operating temperature range: -40°C ~ 70°C

The substitute part RYA31009 meets all electrical and mechanical equivalence criteria. The primary distinction is product status (Active versus Obsolete) and contact material composition (Silver Nickel versus Silver Cadmium Oxide), with the substitute offering improved compliance status and RoHS certification.

Parameter Comparison

Engineering Selection Recommendations

The RYA31009 is the direct substitute for the obsolete 1393224-3 relay. Both components share identical electrical performance specifications and mechanical form factors, ensuring functional interchangeability in circuit applications.

The RYA31009 offers the following advantages:

Product Status: Active product status ensures ongoing manufacturer support, availability, and technical documentation access. The 1393224-3 is classified as Obsolete, limiting future procurement options.

Regulatory Compliance: The RYA31009 is RoHS Compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution. This compliance status is critical for applications subject to RoHS directives and similar regulatory frameworks.

Contact Material: The RYA31009 utilizes Silver Nickel (AgNi) contact material, which is compliant with modern environmental standards. The original 1393224-3 uses Silver Cadmium Oxide (AgCdO), a material restricted under RoHS regulations.

Moisture Sensitivity: The RYA31009 carries MSL 1 (Unlimited) rating, indicating superior moisture handling characteristics compared to the Not Applicable rating of the original part.

For new designs and ongoing production, the RYA31009 is the appropriate selection. For legacy system maintenance requiring exact historical component matching, the 1393224-3 remains available in current inventory (795 pieces).

Frequently Asked Questions (FAQ)

Q: Can the RYA31009 be used as a direct replacement for the 1393224-3 in existing circuit designs?

A: Yes. The RYA31009 meets all electrical and mechanical specifications of the 1393224-3, including coil voltage (9VDC), contact form (SPST-NO), current rating (8A), switching voltage (400VAC), timing characteristics (9ms operate, 5ms release), and operating temperature range (-40°C to 70°C). Both components feature identical Through Hole mounting and PC Pin termination.

Q: What is the primary difference between these two relays?

A: The primary differences are product status and regulatory compliance. The 1393224-3 is Obsolete, while the RYA31009 is Active. The RYA31009 is RoHS Compliant with Silver Nickel contacts, whereas the 1393224-3 uses Silver Cadmium Oxide contacts. Both relays deliver identical functional performance.

Q: Are there any compatibility concerns when substituting the RYA31009 for the 1393224-3?

A: No compatibility concerns exist. Both relays share identical coil resistance (320 Ohms), coil current (28.1 mA), must-operate voltage (6.3 VDC), must-release voltage (0.9 VDC), and thermal operating range. Physical form factor and pin configuration are identical.

Q: Why should I consider the RYA31009 over the 1393224-3?

A: The RYA31009 is the recommended selection for new designs and ongoing production due to Active product status, RoHS compliance, and improved environmental material standards. The 1393224-3, being Obsolete, presents long-term supply chain risk and does not meet current regulatory requirements.

Q: Is the RYA31009 available in the same packaging as the 1393224-3?

A: Both relays utilize identical Through Hole mounting and PC Pin termination. Both are fully sealed relays suitable for PCB assembly and industrial applications.

Q: What is the operating temperature range for both relays?

A: Both the 1393224-3 and RYA31009 operate across the temperature range of -40°C to 70°C, ensuring performance consistency across industrial and commercial environmental conditions.

Q: Can these relays handle 400VAC switching?

A: Yes. Both relays are rated for 400VAC maximum switching voltage with 8A contact current capacity, suitable for general-purpose AC and DC switching applications.
