Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RYA30005 is determined by matching the following critical electrical and mechanical parameters:

• Coil Voltage: 5VDC (exact match required)
• Contact Form: SPST-NO (1 Form A) (exact match required)
• Contact Rating (Current): 8 A (exact match required)
• Switching Voltage: 400VAC maximum (exact match required)
• Coil Current: 44.6 mA (exact match required)
• Coil Resistance: 112 Ohms (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Operating Temperature Range: -40°C ~ 70°C (exact match required)
• Seal Rating: Sealed - Fully (exact match required)
• Coil Type: Non Latching (exact match required)

The RYA31005 meets all substitution criteria for the RYA30005. Both relays share identical electrical specifications, mechanical configuration, and operational characteristics. The primary distinction between these parts is product status and contact material composition.

Parameter Comparison

Engineering Selection Recommendations

The RYA31005 is the direct substitute for the obsolete RYA30005. Both relays are electrically and mechanically equivalent across all specified parameters. The RYA31005 offers the advantage of active product status, ensuring continued availability and manufacturing support.

The RYA31005 provides enhanced regulatory compliance through ROHS3 certification and REACH unaffected status, making it suitable for applications subject to environmental and hazardous substance restrictions. The contact material differs between the two parts (silver nickel in the RYA31005 versus silver cadmium oxide in the RYA30005), but both materials are specified for the same electrical performance envelope.

For new designs or replacement procurement, the RYA31005 is the appropriate selection. The active product status and regulatory compliance certifications of the RYA31005 support long-term supply chain reliability and regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can the RYA31005 directly replace the RYA30005 in existing applications?

A: Yes. The RYA31005 meets all electrical and mechanical specifications of the RYA30005. Both relays share identical coil voltage, contact form, current rating, switching voltage, coil current, coil resistance, mounting type, termination style, operating temperature range, seal rating, and coil type. Direct substitution is supported without circuit modification.

Q: What is the difference between the contact materials used in these relays?

A: The RYA30005 uses silver cadmium oxide (AgCdO) contact material, while the RYA31005 uses silver nickel (AgNi) contact material. Both materials are specified for the same electrical performance within the 8A contact rating and 400VAC switching voltage envelope.

Q: Why is the RYA30005 classified as obsolete?

A: The RYA30005 is no longer in active production. The RYA31005 represents the current active equivalent from TE Connectivity Potter & Brumfield Relays and is the recommended selection for ongoing procurement and new designs.

Q: Are there packaging differences between the RYA30005 and RYA31005?

A: The RYA30005 is supplied in standard packaging, while the RYA31005 is supplied in bulk packaging. Both parts use identical through-hole PC pin termination and are suitable for the same mounting applications.

Q: Does the RYA31005 meet current regulatory requirements?

A: Yes. The RYA31005 is ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations. The RYA30005 regulatory status is not specified in available documentation.

Q: Are the electrical performance characteristics identical between these relays?

A: Yes. Both relays share identical must operate voltage (3.5 VDC), must release voltage (0.5 VDC), operate time (9 ms), and release time (5 ms). Coil resistance is 112 Ohms for both parts.
