Phoenix Contact 5603154 General Purpose Relay SPDT 6A 24VDC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5603154 is a general purpose relay with SPDT (Single Pole Double Throw) contact configuration, rated for 6A at 24VDC coil voltage. This relay is designed for DIN rail mounting with screw terminal connections and includes a lighted indicator and socket. The part is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Phoenix Contact 5603154 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 24VDC
• Contact configuration: SPDT (1 Form C)
• Contact current rating: 6 A
• Switching voltage: 250VAC, 250VDC maximum
• Coil current: 9 mA
• Mounting type: DIN Rail
• Termination style: Screw Terminal
• Contact material: Silver Tin Oxide (AgSnO)
• Operate and release times: 5 ms and 8 ms respectively

Two substitute parts meet these criteria: Phoenix Contact 2909524 and Phoenix Contact 2966171. Both are from the same PLC-RSC series and maintain identical electrical and mechanical specifications. The primary distinction between these substitutes and the original part is product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 2909524 and 2966171 are functionally equivalent to the obsolete 5603154 across all critical electrical and mechanical parameters. Selection between these substitutes should be based on the following factors:

Phoenix Contact 2909524: This part is active in production and carries ROHS3 compliance with REACH Affected status. It features an extended operating temperature range of -40°C to 60°C, providing broader environmental tolerance compared to the original specification. This part is suitable for applications requiring enhanced low-temperature performance.

Phoenix Contact 2966171: This part is active in production and carries ROHS3 compliance with REACH Affected status. It maintains the original operating temperature range of -25°C to 60°C and includes MSL rating of 1 (Unlimited), matching the moisture sensitivity specification of the original part. This part provides the closest parametric alignment to the obsolete 5603154.

Both parts are available in bulk packaging and maintain full compatibility with existing DIN rail installations using screw terminal connections.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 2909524 or 2966171 directly replace the obsolete 5603154 in existing installations?

A: Yes. Both substitute parts maintain identical electrical specifications including 24VDC coil voltage, SPDT contact configuration, 6A current rating, and 250VAC/250VDC switching voltage. Both are DIN rail mounted with screw terminal connections and include lighted indicators with sockets. Direct mechanical and electrical compatibility is confirmed.

Q: What is the difference between the two substitute parts?

A: The primary differences are operating temperature range and moisture sensitivity level. Part 2909524 extends the low-temperature operating limit to -40°C, while part 2966171 maintains the original -25°C specification. Part 2966171 retains the MSL rating of 1 (Unlimited) matching the original part. Both carry ROHS3 and REACH Affected certifications.

Q: Are there packaging differences between the substitute parts?

A: Both substitute parts are supplied in bulk packaging. The original 5603154 was supplied with unspecified packaging. Bulk packaging is standard for active production parts and does not affect electrical or mechanical compatibility.

Q: Do the substitute parts have the same coil current and switching characteristics?

A: Yes. Both substitute parts maintain identical coil current of 9 mA, operate time of 5 ms, and release time of 8 ms. Contact material remains Silver Tin Oxide (AgSnO) for both substitutes.

Q: Which substitute part should be selected for new designs or system upgrades?

A: Selection depends on environmental requirements. For applications requiring extended low-temperature operation below -25°C, part 2909524 is appropriate. For applications matching the original environmental specifications, part 2966171 provides the closest parametric alignment. Both parts are suitable for direct replacement in existing installations.
