Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Phoenix Contact 1873045 is determined by the following critical parameters:

Position and Level Configuration: Both the main part and substitute must maintain 4 positions across 2 levels to ensure mechanical and electrical compatibility with existing receptacle connections.

Terminal Pitch and Spacing: The terminal width specification (5.1mm for the main part, 5.2mm for the substitute) represents the center-to-center spacing of connection points. A 0.1mm variance falls within acceptable mechanical tolerance for plug-receptacle mating in this product category.

Termination Method: Both components utilize identical push-in spring termination with plug receptacles, ensuring functional equivalence in installation and removal procedures.

Electrical Ratings: The substitute part maintains the same voltage rating (250V IEC) and supports the required current capacity through its wire gauge range. The substitute's expanded wire gauge range (12-26 AWG vs. 14-26 AWG) and wire cross-section range (0.14-4mm² vs. 0.2-2.5mm²) provides broader application flexibility while maintaining minimum performance thresholds.

Housing and Mounting: Identical green and yellow housing color scheme and DIN rail mounting type ensure physical interchangeability in panel installations.

Compliance Standards: Both components meet UL94 V-0 flammability requirements and RoHS compliance, maintaining regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3210897 serves as a direct functional substitute for the obsolete 1873045 terminal block. Both components are manufactured by Phoenix Contact and maintain identical mechanical interfaces, electrical termination methods, and safety certifications.

The substitute part 3210897 is classified as active product status, ensuring ongoing availability and supply chain continuity. This addresses the primary limitation of the main part, which is obsolete and subject to inventory depletion.

Both components meet UL94 V-0 flammability requirements and RoHS compliance, maintaining regulatory equivalence for applications requiring these certifications.

The 0.1mm terminal pitch variance (5.1mm to 5.2mm) represents a minor dimensional change within acceptable mechanical tolerance for plug-receptacle mating in this terminal block category. The substitute's expanded wire gauge acceptance range provides additional flexibility for conductor sizing without compromising minimum performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3210897 directly replace the 1873045 in existing installations?

A: Yes. Both components share identical 4-position, 2-level configurations with plug receptacle termination. The 0.1mm terminal pitch variance falls within mechanical tolerance for mating connections. Existing receptacle connections designed for the 1873045 will accommodate the 3210897 without modification.

Q: What is the significance of the terminal width difference (5.1mm vs. 5.2mm)?

A: Terminal width specifies center-to-center spacing of connection points. The 0.1mm increase in the substitute part remains within acceptable mechanical tolerance for plug-receptacle engagement in this product category and does not affect functional compatibility.

Q: Does the expanded wire gauge range of the 3210897 affect compatibility?

A: No. The substitute part's wire gauge range (12-26 AWG, 0.14-4mm²) fully encompasses the main part's range (14-26 AWG, 0.2-2.5mm²). This expansion provides additional application flexibility while maintaining all specifications required by the original part.

Q: Are there compliance or certification differences between these parts?

A: Both components meet identical safety and environmental standards: UL94 V-0 flammability rating and RoHS compliance. No compliance gaps exist between the main part and substitute.

Q: Why is the 1873045 classified as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The Phoenix Contact 3210897 represents the active product line continuation, offering equivalent functionality with ongoing manufacturing support and supply availability.

Q: What packaging differences exist between these parts?

A: The main part packaging is not specified in available data. The substitute part 3210897 is supplied in box packaging. Verify packaging requirements for your procurement process.
