Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2700525 is identified as a manufacturer-recommended substitute for the 2901417. Substitution eligibility is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Mounting type: Both parts mount on DIN rail
• Contact rating: Both rated at 6 A maximum current
• Maximum switching voltage: Both rated 250VAC, 250VDC
• Series family: Both belong to the PSR safety relay series
• Regulatory compliance: Both are RoHS compliant and classified as EAR99

Functional Differences: The 2700525 operates with a coil voltage range of 24 ~ 230VAC/DC, providing broader voltage compatibility compared to the fixed 48VAC/DC requirement of the 2901417. The contact configuration differs: the 2700525 provides 3PST-NO (3 Form A contacts only), whereas the 2901417 provides 4PST with mixed contact forms (3 Form A, 1 Form B). The 2700525 features screwless clamp termination instead of spring terminals and operates across an extended temperature range of -40°C ~ 55°C.

Parameter Comparison

Engineering Selection Recommendations

The 2700525 is the manufacturer-recommended substitute for the obsolete 2901417. Both components maintain identical contact current ratings (6 A) and maximum switching voltages (250VAC/250VDC), ensuring equivalent load-handling capability in DIN rail installations.

The 2700525 offers active product status with current manufacturing support, whereas the 2901417 is obsolete. The substitute achieves ROHS3 compliance, representing current regulatory standards. Both components carry EAR99 classification.

Selection of the 2700525 requires evaluation of application-specific requirements regarding contact configuration. The 2901417 provides four poles with mixed contact forms (3 normally open, 1 normally closed), while the 2700525 provides three poles with normally open contacts only. Applications requiring the fourth pole or the normally closed contact form cannot use the 2700525 as a direct substitute without circuit redesign.

The coil voltage range of the 2700525 (24 ~ 230VAC/DC) accommodates the 48VAC/DC requirement of the original application, providing operational flexibility for future voltage adjustments within the specified range.

Frequently Asked Questions (FAQ)

Q: Can the 2700525 directly replace the 2901417 in existing installations?

A: Direct replacement is possible only if the application circuit does not require the fourth pole or the normally closed contact form provided by the 2901417. The 2700525 provides three normally open poles, whereas the 2901417 provides three normally open and one normally closed pole. Circuit redesign may be necessary if the normally closed contact is essential to system operation.

Q: What are the key differences in contact configuration between these parts?

A: The 2901417 provides 4PST-3NO/1NC configuration (four poles total: three Form A contacts and one Form B contact). The 2700525 provides 3PST-NO configuration (three poles, all Form A contacts). This difference affects circuit design and control logic implementation.

Q: Are both relays suitable for the same switching voltage applications?

A: Yes. Both the 2901417 and 2700525 are rated for maximum switching voltages of 250VAC and 250VDC, making them suitable for equivalent load voltage applications.

Q: How do the coil voltage specifications differ?

A: The 2901417 operates on a fixed 48VAC/DC coil voltage. The 2700525 operates across a range of 24 ~ 230VAC/DC. Applications using 48VAC/DC coil voltage fall within the 2700525 operating range, allowing substitution from a coil voltage perspective.

Q: What is the significance of the different termination styles?

A: The 2901417 uses spring terminal connections, while the 2700525 uses screwless clamp termination. Installation procedures and wiring practices differ between these termination types. Screwless clamp terminals typically provide faster installation and reduced connection maintenance compared to spring terminals.

Q: Does the temperature operating range affect substitution suitability?

A: The 2901417 operates from -25°C to 55°C, while the 2700525 operates from -40°C to 55°C. The 2700525 provides extended low-temperature capability. For applications within the -25°C to 55°C range, both relays are suitable. Applications requiring operation below -25°C benefit from the 2700525 extended range.

Q: What is the impact of different operate and release times?

A: The 2901417 has an operate time of 40 ms and release time of 90 ms. The 2700525 has an operate time of 150 ms and release time of 20 ms. Applications with timing-critical control sequences must evaluate whether these differences affect system performance and safety requirements.

Q: Are both relays RoHS compliant?

A: Yes. The 2901417 is RoHS compliant. The 2700525 is ROHS3 compliant, representing current regulatory standards. Both meet environmental compliance requirements for electronic component manufacturing and use.
