Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 3-1416100-7 is determined by electrical and mechanical parameter equivalence within the SNR/SCHRACK series. The substitute part ST3P3LC4 maintains identical electrical specifications across all critical parameters: 24VDC coil voltage, SPDT contact configuration, 6A contact rating, 400VAC maximum switching voltage, 7mA coil current, 3.4kOhms coil resistance, and identical operate/release timing characteristics. Both parts operate within the same temperature range (-40°C ~ 55°C) and utilize silver tin oxide contact material with full sealing.

The primary distinction between the main part and its substitute is the termination style: the 3-1416100-7 employs spring terminals, while the ST3P3LC4 uses screw terminals. Both configurations are compatible with DIN rail mounting and provide equivalent electrical performance. The ST3P3LC4 is classified as active product status with ROHS3 compliance and REACH unaffected designation, ensuring regulatory alignment for current applications.

Parameter Comparison

Engineering Selection Recommendations

The ST3P3LC4 serves as the direct functional equivalent for the obsolete 3-1416100-7 based on complete electrical parameter alignment and identical mechanical mounting specifications. Selection of ST3P3LC4 is supported by its active product status, ensuring long-term availability and supply chain continuity. The substitute part carries ROHS3 compliance and REACH unaffected designation, meeting current regulatory requirements for industrial and commercial applications.

The termination style difference (spring terminal versus screw terminal) requires evaluation within the specific application context. Screw terminal connections in the ST3P3LC4 provide enhanced mechanical security and are standard in modern DIN rail relay installations. Applications currently utilizing spring terminal connections must accommodate wiring reconfiguration to screw terminal specifications.

Both parts maintain identical electrical performance characteristics, including coil voltage, contact ratings, switching voltage capacity, and timing parameters. The fully sealed construction and silver tin oxide contact material ensure equivalent reliability and contact longevity across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ST3P3LC4 directly replace 3-1416100-7 in existing installations?

A: Electrical substitution is complete. Physical installation requires verification of termination compatibility. The ST3P3LC4 uses screw terminals instead of spring terminals, necessitating wiring reconfiguration to the screw terminal connection points.

Q: Are the coil specifications identical between these parts?

A: Yes. Both parts operate at 24VDC with 7mA coil current, 3.4kOhms coil resistance, 16.8VDC must-operate voltage, and 1.2VDC must-release voltage. Timing characteristics are identical at 12ms operate time and 5ms release time.

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

A: The 3-1416100-7 is classified as obsolete, indicating discontinued manufacturing and limited availability. The ST3P3LC4 is active product, ensuring continued manufacturing, availability, and supply chain support for new designs and field replacements.

Q: Do both relays support the same switching voltage and current ratings?

A: Yes. Both parts are rated for 6A contact current and 400VAC maximum switching voltage. Contact form configuration is identical SPDT (1 Form C) for both parts.

Q: What are the compliance differences between these parts?

A: The ST3P3LC4 carries ROHS3 compliance and REACH unaffected designation. The 3-1416100-7 compliance status is not specified. For applications requiring regulatory compliance documentation, ST3P3LC4 provides current certification.

Q: Are the operating temperature ranges equivalent?

A: Yes. Both parts operate across the identical temperature range of -40°C to 55°C with fully sealed construction and silver tin oxide contact material.

Q: What is the primary technical consideration for substitution?

A: Termination style is the primary installation consideration. Electrical and mechanical parameters are fully equivalent. Wiring connections must be adapted from spring terminals to screw terminals.
