Substitute Part Grouping Explanation

Substitution for the Phoenix Contact 5603157 is determined by strict equivalence across the following critical parameters:

• Contact configuration: SPDT (1 Form C)
• Coil voltage: 120VAC/DC
• Contact current rating: 6 A
• Switching voltage: 250VAC, 250VDC maximum
• Coil current: 4.6 mA
• Mounting type: DIN Rail
• Termination style: Screw Terminal
• Contact material: Silver Tin Oxide (AgSnO)
• Coil type: Non Latching
• Features: Lighted Indicator, Socket Included
• Operate and release times: 6 ms and 15 ms respectively

The substitute parts identified (2909525 and 2966197) maintain full electrical and mechanical compatibility across all specified parameters. Both alternatives are active products from Phoenix Contact within the PLC-RSC series, providing direct functional replacement capability.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (2909525 and 2966197) are active products with current manufacturing status, addressing the obsolescence of the original 5603157. Selection between the two alternatives depends on application-specific requirements:

Part 2909525 offers an extended operating temperature range of -40°C to 60°C compared to the original specification of -25°C to 55°C, providing enhanced performance in extreme temperature environments. This part carries ROHS3 compliance and REACH affected status.

Part 2966197 maintains the original operating temperature range of -25°C to 55°C and carries ROHS3 compliance with REACH affected status, providing direct functional equivalence with minimal specification variance.

Both parts are available in bulk packaging and maintain full electrical and mechanical compatibility with the original 5603157 across all critical parameters including contact configuration, coil voltage, current ratings, and switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 2909525 and 2966197 be used interchangeably with the obsolete 5603157?

A: Both parts maintain full electrical and mechanical compatibility with the 5603157 across all specified parameters including SPDT contact form, 120VAC/DC coil voltage, 6A contact rating, and screw terminal connections.
