Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4-1393225-0 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Coil voltage must be 48VDC
• Contact form must be SPDT (1 Form C)
• Contact current rating must be 8 A minimum
• Switching voltage rating must support 400VAC maximum
• Coil current must be 5.1 mA
• Coil type must be non-latching
• Operating temperature range must encompass -40°C to 70°C

Mechanical Compatibility Requirements:

• Mounting type must be through-hole
• Termination style must be PC pin
• Seal rating must provide flux protection

The substitute part RY211048 satisfies all electrical and mechanical compatibility criteria. Both parts share identical coil voltage, contact configuration, current ratings, switching voltage capability, coil current draw, mounting methodology, and environmental operating parameters. The primary distinction between these parts is product status (obsolete versus active) and contact material composition (Silver Cadmium Oxide versus Silver Nickel), with the latter offering improved environmental compliance.

Parameter Comparison

Engineering Selection Recommendations

The RY211048 is the direct active equivalent for the obsolete 4-1393225-0. Selection of RY211048 is supported by the following engineering factors:

Product Status Consideration: The 4-1393225-0 is classified as obsolete. The RY211048 maintains active product status with TE Connectivity, ensuring continued availability, technical support, and manufacturing consistency for new designs and production continuity.

Compliance and Certification: The RY211048 carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. These certifications are not specified for the obsolete 4-1393225-0.

Electrical and Mechanical Equivalence: All critical electrical parameters (coil voltage, contact configuration, current ratings, switching voltage, coil current, timing characteristics, and operating temperature range) are identical between the two parts. Mechanical compatibility is confirmed through identical mounting type, termination style, and seal rating.

Contact Material Difference: The substitute part employs Silver Nickel (AgNi) contact material in place of Silver Cadmium Oxide (AgCdO). This change reflects modern manufacturing practices and environmental compliance standards while maintaining electrical performance within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RY211048 be used as a direct replacement for 4-1393225-0 in existing designs?

A: Yes. The RY211048 is electrically and mechanically equivalent to the 4-1393225-0. Both parts share identical coil voltage (48VDC), contact configuration (SPDT), current ratings (8A), switching voltage capability (400VAC), mounting type (through-hole), and termination style (PC pin). The parts are pin-compatible and functionally interchangeable.

Q: What is the significance of the contact material difference between these parts?

A: The 4-1393225-0 uses Silver Cadmium Oxide (AgCdO) contact material, while the RY211048 uses Silver Nickel (AgNi). Both materials meet the specified electrical performance requirements. The change to Silver Nickel reflects current manufacturing standards and environmental compliance practices. Electrical performance, switching characteristics, and current-carrying capacity remain equivalent.

Q: Why is the 4-1393225-0 listed as obsolete?

A: The 4-1393225-0 is classified as obsolete by TE Connectivity. The RY211048 represents the active product line continuation. For new designs and ongoing production, RY211048 should be specified to ensure component availability and manufacturer support.

Q: Are there packaging differences between these parts?

A: The 4-1393225-0 is specified with packaging designation "-" while RY211048 is supplied in bulk packaging. Both parts use identical through-hole PC pin termination. Packaging differences do not affect electrical or mechanical compatibility.

Q: What compliance certifications apply to the RY211048?

A: The RY211048 is ROHS3 compliant and REACH unaffected. These certifications confirm compliance with current environmental and hazardous substance regulations applicable to electronic components in most markets.

Q: Are the coil resistance values identical?

A: The coil resistance values are equivalent. The 4-1393225-0 specifies 9.39 kOhms while the RY211048 specifies 9.4 kOhms. This minor variation (0.01 kOhms) is within normal manufacturing tolerance and does not affect circuit performance or compatibility.

Q: Do both parts operate within the same temperature range?

A: Yes. Both the 4-1393225-0 and RY211048 operate across the identical temperature range of -40°C to 70°C. Operating voltage thresholds (must operate at 33.6 VDC, must release at 4.8 VDC) are also identical.
