Key Parameters

Substitute Part Grouping Explanation

Substitution of the RYA30012 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Coil voltage must be 12VDC
• Contact form must be SPST-NO (1 Form A)
• Contact current rating must be 8 A minimum
• Switching voltage rating must support 400VAC maximum
• Coil current must be 19.2 mA
• Coil resistance must be 627 Ohms
• Operating temperature range must encompass -40°C ~ 70°C

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Termination style must be PC Pin
• Seal rating must be Sealed - Fully
• Coil type must be Non Latching

The RYA31012 satisfies all electrical and mechanical compatibility criteria and is classified as a direct substitute for the RYA30012.

Parameter Comparison

Engineering Selection Recommendations

The RYA31012 is the direct substitute for the obsolete RYA30012. Both components share identical electrical and mechanical specifications across all critical parameters including coil voltage, contact form, current rating, switching voltage, timing characteristics, and operating temperature range.

The RYA31012 offers the following advantages for new designs and replacement applications:

Product Status: The RYA31012 maintains Active product status, ensuring long-term availability and continued manufacturing support, whereas the RYA30012 is Obsolete.

Regulatory Compliance: The RYA31012 is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.

Contact Material Difference: The RYA31012 uses Silver Nickel (AgNi) contact material compared to the Silver Cadmium Oxide (AgCdO) material in the RYA30012. Both materials are suitable for general purpose switching applications at the specified 8A rating and 400VAC maximum switching voltage. The Silver Nickel composition in the RYA31012 aligns with modern manufacturing practices and regulatory restrictions on cadmium-containing materials.

Inventory Availability: The RYA31012 is available in higher stock quantities (1291 Pcs) compared to the RYA30012 (842 Pcs), supporting production continuity and shorter lead times.

Frequently Asked Questions (FAQ)

Q: Can the RYA31012 be used as a direct replacement for the RYA30012 in existing designs?

A: Yes. The RYA31012 is electrically and mechanically identical to the RYA30012 across all critical parameters. Both components have identical coil voltage (12VDC), contact form (SPST-NO), current rating (8A), switching voltage (400VAC), coil current (19.2 mA), coil resistance (627 Ohms), timing characteristics, and operating temperature range (-40°C ~ 70°C). The through-hole mounting and PC pin termination are identical, allowing direct PCB substitution.

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

A: The RYA30012 uses Silver Cadmium Oxide (AgCdO) contact material, while the RYA31012 uses Silver Nickel (AgNi) contact material. Both materials are rated for the same 8A current and 400VAC switching voltage in general purpose relay applications. The Silver Nickel composition in the RYA31012 reflects current manufacturing standards and regulatory compliance with restrictions on cadmium-containing materials.

Q: Why is the RYA30012 listed as Obsolete?

A: The RYA30012 carries an Obsolete product status, indicating that the manufacturer has discontinued production. The RYA31012 is the active replacement part, maintaining identical electrical and mechanical specifications while offering improved regulatory compliance and manufacturing support.

Q: Are there any packaging differences between these parts?

A: The RYA30012 is specified with packaging listed as a dash (-), while the RYA31012 is supplied in Bulk packaging. Both parts use identical PC pin termination and through-hole mounting. Packaging differences do not affect electrical or mechanical compatibility.

Q: What regulatory certifications apply to the RYA31012?

A: The RYA31012 is ROHS3 Compliant and REACH Unaffected. These certifications confirm compliance with European Union directives restricting hazardous substances and the REACH regulation on chemical safety. The RYA30012 regulatory status is not specified in available documentation.

Q: Are the timing characteristics identical between these relays?

A: Yes. Both the RYA30012 and RYA31012 have identical operate time (9 ms), release time (5 ms), must operate voltage (8.4 VDC), and must release voltage (1.2 VDC). Timing performance is identical for switching applications.

Q: What is the moisture sensitivity level for these relays?

A: Both the RYA30012 and RYA31012 have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
