Phoenix Contact 1897283 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897283 is a 6-position terminal block header with male pins, shrouded on four sides, designed for 90° right-angle through-hole mounting. It operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL) with 4.6mm pitch spacing. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897283 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (8A IEC/UL), voltage rating (250V IEC / 300V UL), and contact mating finish (tin)
• Mechanical Compatibility: 6 positions, 0.138" (4.6mm) pitch, 90° right-angle orientation, through-hole mounting, male pins with 4-side shrouding
• Material & Safety Compliance: PBT housing, UL94 V-0 flammability rating, RoHS compliance status
• Termination Interface: The main part uses press-fit termination; substitute parts may employ alternative termination methods (such as solder) while maintaining electrical and mechanical compatibility

The Phoenix Contact 1843839 qualifies as a functional substitute based on matching electrical ratings, mechanical dimensions, pitch spacing, orientation, and safety certifications. Differences in termination style (solder vs. press-fit) and minor dimensional variations in contact tail length and insulation height do not preclude substitution in applications where the mounting method is compatible with the receiving PCB or assembly.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The Phoenix Contact 1843839 is the primary substitute for the 1897283. Both components maintain identical electrical performance (8A/250V IEC, 8A/300V UL) and mechanical form factor (6 positions, 4.6mm pitch, 90° right-angle, through-hole, male pins, 4-side shrouded).

Compliance Considerations: The 1843839 carries active product status with ROHS3 compliance, compared to the obsolete 1897283 with RoHS compliance. Both meet UL94 V-0 flammability requirements and employ PBT housing material.

Termination Method Transition: The primary difference is termination style—the 1897283 uses press-fit termination while the 1843839 employs solder termination. This distinction requires PCB design compatibility assessment. Press-fit termination uses mechanical insertion into plated through-holes, whereas solder termination requires traditional wave or reflow soldering processes.

Dimensional Tolerance: Minor variations exist in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285"). These differences fall within standard manufacturing tolerances and do not affect electrical or mechanical compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the 1843839 directly replace the 1897283 in existing designs? A: Electrical and mechanical compatibility is confirmed. Substitution feasibility depends on PCB mounting method compatibility. If the original design uses press-fit mounting holes, the solder-terminated 1843839 requires PCB redesign to accommodate solder pads. If the PCB supports solder termination, direct substitution is viable.

Q: What is the significance of the termination style difference? A: Press-fit termination (1897283) uses mechanical insertion into precision-drilled holes without solder. Solder termination (1843839) requires thermal attachment via soldering. The choice affects PCB layout, assembly process, and rework capability. Both methods provide equivalent electrical performance when properly implemented.

Q: Are there any electrical performance differences between these parts? A: No. Both components are rated at 8A (IEC/UL) and 250V (IEC) / 300V (UL) with identical pitch spacing, position count, and shrouding configuration. Electrical performance is equivalent.

Q: Why is the 1897283 listed as obsolete? A: Product obsolescence reflects manufacturer discontinuation. The 1843839 represents the active-status successor within the Phoenix Contact COMBICON terminal block family, offering equivalent functionality with current manufacturing support.

Q: Does the minor dimensional variation affect mechanical fit? A: The contact tail length difference (0.138" vs. 0.134") and insulation height variation (0.276" vs. 0.285") are within standard manufacturing tolerances. These variations do not affect mechanical fit in standard through-hole applications.

Q: What compliance certifications apply to both parts? A: Both components meet UL94 V-0 flammability requirements and RoHS environmental compliance. The 1843839 carries ROHS3 certification, representing the current regulatory standard. Both employ tin contact mating finish and PBT housing material.
