Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 910597 is determined by the following critical parameters:

Primary Substitution Criteria:

• Mounting Type: DIN Rail
• Coil Voltage: 120VAC
• Contact Form: SPDT (1 Form C)
• Contact Rating (Current): 10 A
• Coil Type: Non Latching
• Termination Style: Screw Terminal

Parametric Equivalent Classification: The Weidmüller 910481 is classified as a parametric equivalent. This part maintains identical electrical specifications across all primary substitution criteria, including coil voltage, contact configuration, current rating, and coil resistance. The primary distinction is product status: 910481 is active, whereas 910597 is obsolete.

Similar Substitute Classification: The Phoenix Contact 2903356 is classified as a similar substitute. While this part shares the same mounting type, coil voltage, contact form, and current rating, it exhibits variations in secondary parameters including switching voltage capability (250VAC/250VDC vs. 240VAC), coil current (8 mA vs. 7.5 mA), contact material (Silver Nickel vs. Silver Cadmium Oxide), operating temperature range (-40°C ~ 50°C vs. -25°C ~ 40°C), and coil resistance (15 kOhms vs. 7.68 kOhms). These differences require engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): The Weidmüller 910481 is the primary substitute for the obsolete 910597. Both parts maintain identical electrical and mechanical specifications, including coil voltage, contact configuration, current rating, coil resistance, and operating characteristics. The 910481 is currently in active production status with confirmed inventory availability. This part is suitable for direct substitution without circuit modification.

For Alternative Selection (Similar Substitute): The Phoenix Contact 2903356 provides an alternative option when the parametric equivalent is unavailable. This part meets the core functional requirements of DIN rail mounting, 120VAC coil voltage, SPDT contact configuration, and 10A current rating. However, the following parameter variations require engineering assessment:

• Coil resistance differs (15 kOhms vs. 7.68 kOhms), affecting coil current draw and power consumption
• Switching voltage capability is enhanced (250VAC/250VDC vs. 240VAC)
• Operating temperature range is extended (-40°C ~ 50°C vs. -25°C ~ 40°C)
• Contact material differs (Silver Nickel vs. Silver Cadmium Oxide), affecting contact performance characteristics
• Operate time is faster (12 ms vs. 20 ms)
• Includes integrated varistor protection

Compliance Considerations: Both substitute parts maintain RoHS compliance. The 910481 matches the original RoHS status, while the 2903356 meets ROHS3 requirements. The Phoenix Contact part is REACH Affected, whereas the Weidmüller parts are REACH Unaffected. Regulatory compliance verification is required for applications subject to specific environmental or procurement standards.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 910481 be used as a direct replacement for the 910597? A: Yes. The 910481 is a parametric equivalent with identical electrical specifications, including coil voltage (120VAC), contact configuration (SPDT), current rating (10A), coil resistance (7.68 kOhms), and operating characteristics. No circuit modifications are required.

Q: What are the key differences between the Weidmüller 910481 and Phoenix Contact 2903356? A: The primary differences are coil resistance (7.68 kOhms vs. 15 kOhms), switching voltage capability (240VAC vs. 250VAC/250VDC), contact material (Silver Cadmium Oxide vs. Silver Nickel), operating temperature range (-25°C ~ 40°C vs. -40°C ~ 50°C), and operate time (20 ms vs. 12 ms). The Phoenix Contact part includes integrated varistor protection.

Q: Is the Phoenix Contact 2903356 suitable for applications requiring the exact coil resistance of the original 910597? A: No. The 2903356 has a coil resistance of 15 kOhms compared to the 910597's 7.68 kOhms. This difference affects coil current draw and power consumption. Applications with strict power budget requirements or coil current specifications should use the Weidmüller 910481 instead.

Q: Are there packaging differences between these parts? A: The Weidmüller 910597 is packaged as individual units, while both the 910481 and 2903356 are supplied in bulk packaging. Verify packaging requirements for procurement and inventory management.

Q: What is the impact of the different contact materials on relay performance? A: The 910597 and 910481 use Silver Cadmium Oxide (AgCdO) contacts, while the 2903356 uses Silver Nickel (AgNi) contacts. Contact material affects electrical conductivity, wear characteristics, and suitability for specific load types. Applications with established performance history using AgCdO contacts should prioritize the Weidmüller 910481.

Q: Can the Phoenix Contact 2903356 be used in applications with extended temperature requirements? A: Yes. The 2903356 operates across -40°C ~ 50°C, compared to the 910597's -25°C ~ 40°C range. For applications requiring operation below -25°C or above 40°C, the Phoenix Contact part provides extended temperature capability.

Q: What compliance certifications apply to each part? A: All three parts are RoHS compliant. The 910597 and 910481 are REACH Unaffected, while the 2903356 is REACH Affected. Verify regulatory requirements for your specific application and region.
