Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1890633 is determined by the following critical parameters:

• Position Count: 4 positions required
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Voltage & Current Ratings: Minimum 300V and 10A capacity
• Wire Gauge Compatibility: Support for 12-30 AWG conductors
• Mounting Configuration: Through-hole PCB mounting
• Termination Method: Screw-based cage clamp connection
• Compliance Requirements: RoHS compliance maintained

The Phoenix Contact 1730418 meets all substitution criteria as an active-status alternative within the same manufacturer's product line, maintaining electrical specifications and mechanical compatibility while offering enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1730418 is the designated substitute for the obsolete 1890633 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical voltage (300V) and current (10A) ratings with matching wire gauge acceptance (12-30 AWG), ensuring direct functional equivalence in circuit applications.

Mechanical Compatibility: The 4-position configuration and 5.08mm pitch specification are preserved, allowing direct PCB footprint compatibility. Both employ screw-rising cage clamp termination, maintaining identical wire connection methodology.

Regulatory Compliance: The 1730418 achieves ROHS3 compliance, exceeding the RoHS compliance of the obsolete 1890633. Both parts carry EAR99 ECCN classification and MSL-1 moisture sensitivity rating, meeting standard industrial requirements.

Product Status: The 1730418 maintains active production status with confirmed inventory availability (1260 units), providing supply chain continuity for the discontinued 1890633.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1730418 directly replace the 1890633 in existing PCB designs?

A: Yes. Both parts share identical pitch (5.08mm), position count (4), voltage/current ratings (300V/10A), wire gauge range (12-30 AWG), and through-hole mounting configuration. PCB footprints are compatible without modification.

Q: What is the primary difference between these two parts?

A: The 1890633 is obsolete with limited availability, while the 1730418 is an active product with current manufacturing and inventory support. The 1730418 provides documented specifications including M3 screw thread and 0.5-0.6 Nm torque requirements.

Q: Are there compliance differences between the two parts?

A: The 1730418 meets ROHS3 compliance, representing an updated regulatory standard compared to the RoHS compliance of the 1890633. Both maintain EAR99 classification and MSL-1 moisture sensitivity rating.

Q: What packaging format is available for the 1730418?

A: The 1730418 is supplied in bulk packaging with 1260 units currently in stock.

Q: Are the screw termination specifications identical?

A: The 1730418 specifies M3 screw thread with 0.5-0.6 Nm torque range. The 1890633 does not provide documented screw specifications, though both employ screw-rising cage clamp termination methodology.
