Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2829917 is determined by the following critical parameters:

• Number of Positions: 3 positions (fixed requirement)
• Mounting Type: DIN Rail (fixed requirement)
• For Use With/Related Products: ST-REL, ST-OV, ST-OE (fixed requirement)
• Type: Socket (fixed requirement)
• RoHS Compliance: Required for regulatory adherence
• Moisture Sensitivity Level: MSL 1 (Unlimited) for environmental stability

The substitute part Phoenix Contact 2777043 maintains compatibility across all critical functional parameters. The primary difference is the termination style transition from spring terminal to screw terminal, which does not affect the socket's ability to interface with the specified relay modules.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2777043 is the direct substitute for the obsolete 2829917. Both components share identical functional specifications for position count, mounting configuration, and relay module compatibility. The 2777043 carries active product status with ROHS3 compliance, providing superior regulatory alignment compared to the obsolete main part.

The transition from spring terminal to screw terminal termination represents the primary design evolution between these components. Both termination styles are compatible with the specified ST-REL, ST-OV, and ST-OE relay modules. The 2777043 is available in bulk packaging with confirmed inventory of 729 pieces.

Frequently Asked Questions (FAQ)

Q: Can the 2777043 directly replace the 2829917 in existing installations?

A: Yes. Both components are 3-position DIN rail sockets designed for the same relay module series (ST-REL, ST-OV, ST-OE). The functional interface remains unchanged.

Q: What is the difference between spring terminal and screw terminal configurations?

A: Spring terminals provide push-in connection capability, while screw terminals require mechanical fastening. Both termination styles are compatible with the specified relay modules. System design must account for the termination method during installation.

Q: Why is the 2829917 listed as obsolete?

A: The 2829917 has been superseded by the 2777043 in Phoenix Contact's product line. The 2777043 represents the current active equivalent with enhanced compliance certifications.

Q: Are there any environmental or compliance differences between these parts?

A: Both components maintain MSL 1 (Unlimited) moisture sensitivity ratings and share identical ECCN and HTSUS classifications. The 2777043 carries ROHS3 compliance versus RoHS compliance for the 2829917, reflecting current regulatory standards.

Q: What packaging options are available for the substitute part?

A: The 2777043 is supplied in bulk packaging with current inventory of 729 pieces.
