Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 4-1415540-2 relay is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Coil voltage: 24VAC (identical)
• Contact form: SPDT (1 Form C) (identical)
• Contact rating: 16A (identical)
• Maximum switching voltage: 400VAC (identical)
• Coil resistance: 350 Ohms (identical)
• Must operate voltage: 18VAC (identical)
• Must release voltage: 3.6VAC (identical)

Mechanical Compatibility Parameters:

• Mounting type: DIN Rail (identical)
• Termination style: Screw Terminal (identical)
• Contact material: Silver Nickel (AgNi) (identical)
• Coil type: Non Latching (identical)
• Features: Lighted Indicator, Socket Included (identical)

The substitute part RT3S4R24 meets all critical electrical and mechanical parameters required for direct substitution. Variations in operating temperature range and product status do not affect functional compatibility within the specified operating envelope of the original application.

Parameter Comparison

Engineering Selection Recommendations

The RT3S4R24 relay is the direct substitute for the obsolete 4-1415540-2 model. Both relays are manufactured by TE Connectivity Potter & Brumfield Relays and share identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 4-1415540-2 is classified as obsolete, while RT3S4R24 maintains active product status with confirmed inventory availability (1237 pieces in stock). This status difference ensures long-term component availability and supply chain continuity.

Compliance Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. The RT3S4R24 carries REACH Affected status, whereas the main part shows Vendor Undefined REACH status. Both parts are classified under ECCN EAR99 and HTSUS 8536.41.0050.

Operating Temperature Consideration: The substitute part operates across -20°C to 70°C, compared to the main part's -40°C to 70°C range. Applications requiring operation below -20°C require evaluation against actual system requirements.

Packaging Difference: The substitute part is supplied in tube packaging, whereas the main part packaging specification is not provided. This difference does not affect functional compatibility but may influence handling and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can RT3S4R24 directly replace 4-1415540-2 in existing installations?

A: Yes. The RT3S4R24 meets all critical electrical and mechanical specifications of the 4-1415540-2, including coil voltage, contact form, current rating, switching voltage, mounting type, and termination style. Direct substitution is supported for applications operating within the -20°C to 70°C temperature range.

Q: What is the difference in coil current between the two relays?

A: The 4-1415540-2 draws 32.1 mA while the RT3S4R24 draws 31.6 mA. This 0.5 mA difference is functionally insignificant and does not affect circuit design or component selection.

Q: Are there temperature range limitations when substituting?

A: The RT3S4R24 operates from -20°C to 70°C, whereas the original part operates from -40°C to 70°C. Applications requiring operation below -20°C must evaluate whether the substitute meets system requirements. Applications within the -20°C to 70°C envelope are fully compatible.

Q: What is the significance of the product status difference?

A: The 4-1415540-2 is obsolete and no longer manufactured. The RT3S4R24 is an active product with confirmed inventory availability, ensuring component availability for new installations and field replacements.

Q: Does packaging affect the substitution decision?

A: The RT3S4R24 is supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility but may influence receiving, storage, and handling procedures. Verify packaging requirements against procurement specifications.

Q: Are both relays RoHS compliant?

A: Yes. Both the 4-1415540-2 and RT3S4R24 are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compliance with environmental and regulatory requirements.

Q: What is the base product number relationship?

A: The 4-1415540-2 carries base product number XT3S4, while the RT3S4R24 carries base product number 1415073. These designations reflect different product series within the TE Connectivity Potter & Brumfield Relays portfolio, with RT3S4R24 representing the active equivalent.
