Electrical Equivalence Criteria:

• Coil voltage: 230VAC
• Contact form: SPDT (1 Form C)
• Contact current rating: 16 A
• Maximum switching voltage: 400VAC
• Coil type: Non Latching
• Contact material: Silver Nickel (AgNi)
• Coil resistance: 32.5 kOhms
• Must operate voltage: 172.5 VAC
• Must release voltage: 34.5 VAC

Mechanical Equivalence Criteria:

• Mounting type: DIN Rail
• Termination style: Screw Terminal
• Features: Lighted Indicator, Socket Included

Compliance Criteria:

• RoHS3 Compliance
• ECCN classification: EAR99
• HTSUS code: 8536.49.0075

The substitute part 6-1415073-1 meets all electrical and mechanical equivalence requirements. Minor variations in operating temperature range and coil current do not affect functional substitution within the specified parameter envelope.

Engineering Selection Recommendations

The substitute part 6-1415073-1 is the direct equivalent for the obsolete 4-1415540-4 relay. Selection of the substitute is based on the following engineering factors:

Product Status: The 4-1415540-4 is classified as obsolete, while the 6-1415073-1 is active and currently manufactured. This ensures long-term availability and supply chain continuity.

Electrical Equivalence: Both relays share identical coil voltage (230VAC), contact form (SPDT), current rating (16A), and switching voltage specifications (400VAC maximum). The substitute exhibits a marginally lower coil current (3.2 mA versus 3.5 mA), which reduces power consumption without affecting functional performance.

Mechanical Compatibility: Both relays feature identical DIN rail mounting, screw terminal connections, and include lighted indicators with sockets. Physical and electrical interfaces are fully compatible.

Compliance Certification: Both parts maintain ROHS3 compliance, identical ECCN classification (EAR99), and matching HTSUS codes. The substitute carries REACH Affected status, indicating full regulatory compliance documentation.

Operating Temperature Consideration: The substitute 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 must retain the original 4-1415540-4 specification or identify alternative solutions.

Availability: The substitute part 6-1415073-1 is available in active inventory (1072 pieces), ensuring immediate procurement capability.

Frequently Asked Questions (FAQ)

Q: Can the 6-1415073-1 directly replace the 4-1415540-4 in existing installations?

A: Yes, the 6-1415073-1 is a direct electrical and mechanical equivalent. Both relays share identical coil voltage, contact configuration, current rating, and DIN rail mounting. Screw terminal connections are compatible. No circuit modifications are required for substitution.

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

A: The 4-1415540-4 draws 3.5 mA, while the 6-1415073-1 draws 3.2 mA. This 0.3 mA reduction in the substitute represents lower power consumption and reduced heat generation. Both values fall within acceptable operating parameters for 230VAC coil circuits.

Q: Are there operating temperature limitations when using the substitute?

A: The 6-1415073-1 operates from -20°C to 70°C, whereas the original 4-1415540-4 operates from -40°C to 70°C. If your application requires operation below -20°C, the substitute is not suitable. Verify your system's minimum operating temperature requirement before substitution.

Q: Do both relays have identical contact ratings and switching specifications?

A: Yes. Both relays are rated for 16A continuous contact current and 400VAC maximum switching voltage. Must operate voltage (172.5 VAC) and must release voltage (34.5 VAC) are identical. Contact material (Silver Nickel) is the same.

Q: What is the packaging difference between these parts?

A: The 4-1415540-4 is supplied with standard packaging, while the 6-1415073-1 is supplied in bulk packaging. This affects order quantities and handling but does not impact electrical or mechanical performance.

Q: Are both relays RoHS3 compliant?

A: Yes, both the 4-1415540-4 and 6-1415073-1 are ROHS3 compliant. Both carry EAR99 ECCN classification and match HTSUS code 8536.49.0075.

Q: Why is the 4-1415540-4 listed as obsolete?

A: The 4-1415540-4 has been discontinued by the manufacturer. The 6-1415073-1 represents the current production equivalent, ensuring ongoing availability and support.

Q: Do both relays include the same features?

A: Yes, both relays include lighted indicators and sockets. Termination is screw terminal on both models. Non-latching coil type is identical.
