Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5603683 is determined by the following critical parameters that must remain constant:

• Contact Form: SPDT (1 Form C)
• Coil Voltage: 120VAC/DC
• Contact Rating (Current): 6 A
• Switching Voltage: 250VAC, 250VDC - Max
• Coil Type: Non Latching
• Mounting Type: DIN Rail
• Termination Style: Spring Terminal
• Contact Material: Silver Tin Oxide (AgSnO)

The Phoenix Contact 2909529 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status: the 2909529 is active and currently manufactured, whereas the 5603683 is obsolete. Both relays operate identically within their specified parameter ranges and are compatible with existing socket and DIN rail installations.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2909529 is the direct substitute for the obsolete 5603683. Selection of the 2909529 is based on:

• Identical electrical specifications across all critical parameters
• Active product status with current manufacturing support
• Enhanced RoHS3 compliance versus RoHS compliance of the original part
• Extended operating temperature range (-40°C to 60°C versus -20°C to 60°C)
• REACH compliance status documented for the substitute
• Identical mechanical compatibility with existing DIN rail installations and socket configurations

The 2909529 operates within the same functional envelope as the 5603683 and requires no circuit modifications or installation changes.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2909529 directly replace the 5603683 in existing installations?

A: Yes. The 2909529 is mechanically and electrically compatible with the 5603683. Both relays mount on DIN rail, use spring terminals, and operate identically at 120VAC/DC coil voltage with 6A contact rating. Socket compatibility is maintained.

Q: What is the primary reason for substitution?

A: The 5603683 is obsolete and no longer manufactured. The 2909529 is an active product from the same manufacturer with identical functional specifications.

Q: Are there differences in operating temperature ranges?

A: The 2909529 operates from -40°C to 60°C, while the 5603683 operates from -20°C to 60°C. The substitute provides an extended lower temperature range, which is compatible with applications requiring the original -20°C to 60°C specification.

Q: Do both relays use the same contact material?

A: Yes. Both the 5603683 and 2909529 use Silver Tin Oxide (AgSnO) contact material, ensuring identical electrical performance and switching characteristics.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current RoHS Directive 2011/65/EU as amended. The 2909529 meets this updated standard, while the 5603683 meets the earlier RoHS Compliant specification. Both are compliant with environmental regulations.

Q: Are packaging differences significant for component selection?

A: The 5603683 is listed with "-" packaging, while the 2909529 is supplied in Bulk packaging. This affects procurement and inventory management but does not impact electrical or mechanical compatibility.
