Key Parameters

Substitute Part Grouping Explanation

Substitution of the RY530048 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Coil voltage: 48VDC
• Contact form: SPST-NO (1 Form A)
• Contact rating: 8 A
• Switching voltage: 400VAC maximum
• Coil current: 5.1 mA
• Operate and release times: 9 ms and 5 ms respectively

Mechanical Specifications:

• Mounting type: Through hole
• Termination style: PC pin
• Seal rating: Sealed with flux protection

Environmental Specifications:

• Operating temperature range: -40°C to 70°C
• Coil type: Non latching

The RY531048 satisfies all critical electrical and mechanical parameters required for direct substitution. Both parts operate identically within the specified parameter envelope, with the primary distinction being product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The RY531048 is the direct active equivalent for the obsolete RY530048. Selection of the RY531048 is supported by the following factors:

Product Status: The RY531048 maintains active product status with current manufacturing support, whereas the RY530048 is classified as obsolete. This ensures long-term component availability and supply chain continuity.

Electrical and Mechanical Equivalence: All critical operating parameters are identical between the two parts, including coil voltage, contact form, current rating, switching voltage, timing characteristics, and environmental specifications.

Regulatory Compliance: The RY531048 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement and deployment.

Contact Material Difference: The RY531048 utilizes Silver Nickel (AgNi) contact material compared to the Silver Cadmium Oxide (AgCdO) material in the RY530048. Both materials are suitable for the specified 8A switching application at 400VAC maximum switching voltage.

Packaging Configuration: The RY531048 is supplied in tube packaging, whereas the RY530048 was supplied in bulk packaging. This represents a packaging format change only and does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can the RY531048 be used as a direct replacement for the RY530048 in existing designs?

A: Yes. The RY531048 is electrically and mechanically equivalent to the RY530048 across all critical parameters including coil voltage, contact form, current rating, switching voltage, timing, and environmental specifications. Both parts are through-hole mounted with PC pin termination and identical operating characteristics.

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

A: The RY530048 uses Silver Cadmium Oxide (AgCdO) contact material, while the RY531048 uses Silver Nickel (AgNi) contact material. Both materials are suitable for the specified 8A contact rating and 400VAC maximum switching voltage. The contact material change does not affect functional performance within the specified operating parameters.

Q: Why is the RY530048 listed as obsolete?

A: The RY530048 has been discontinued by the manufacturer. The RY531048 is the active equivalent part that maintains the same electrical and mechanical specifications while providing current manufacturing support and regulatory compliance.

Q: Are there packaging differences between these parts?

A: Yes. The RY530048 was supplied in bulk packaging, while the RY531048 is supplied in tube packaging. This represents a packaging format change only and does not affect the relay's electrical performance or functionality.

Q: Does the RY531048 meet current regulatory requirements?

A: Yes. The RY531048 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and use in regulated applications.

Q: Are the coil resistance values identical between these parts?

A: The coil resistance values are nominally equivalent. The RY530048 specifies 9.4 kOhms, while the RY531048 specifies 9.391 kOhms. This minor variation falls within normal manufacturing tolerance and does not affect circuit performance.

Q: Can the RY531048 be used in applications requiring the exact AgCdO contact material specification?

A: The RY531048 uses Silver Nickel (AgNi) contact material instead of Silver Cadmium Oxide (AgCdO). If the application requires the specific AgCdO contact material, this substitution may not be suitable. Consult application requirements to determine if contact material specification is critical.
