Phoenix Contact 1897319 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897319 is a 9-position terminal block header with male pins, shrouded on four sides, featuring a 0.138" (4.60mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL), with UL94 V-0 flammability rating and RoHS compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897319 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (8A IEC/UL), voltage rating (250V IEC / 300V UL)
• Physical Compatibility: 9 positions, 0.138" (4.60mm) pitch, 90° right-angle orientation, through-hole mounting
• Mechanical Compatibility: Header type with male pins, shrouded (4 side) design, mating and mounting flange
• Material & Compliance: PBT housing, UL94 V-0 flammability rating, RoHS compliance

The substitute part Phoenix Contact 1843868 meets all critical electrical and mechanical parameters. Differences in termination style (press-fit vs. solder), series designation (COMBICON EMC vs. COMBICON MC), and minor dimensional variations in contact tail length and insulation height do not preclude functional substitution when mounting and soldering methods are appropriately adapted.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843868 is an active-status substitute for the obsolete 1897319. Both components share identical electrical ratings, pitch, position count, and orientation specifications. The primary distinction is termination methodology: the 1897319 uses press-fit termination, while the 1843868 employs solder termination. This difference requires appropriate PCB design and assembly process adaptation.

The 1843868 offers enhanced compliance status (ROHS3 vs. RoHS Compliant) and maintains equivalent electrical performance and material specifications. Minor dimensional variations in contact tail length (0.004" difference) and insulation height (0.009" difference) fall within acceptable tolerances for standard through-hole PCB applications and do not compromise functional compatibility.

Selection of the 1843868 is supported by its active product status, ensuring long-term availability and supply chain continuity compared to the obsolete 1897319.

Frequently Asked Questions (FAQ)

Q: Can the 1843868 directly replace the 1897319 without PCB modifications?

A: Electrical and positional compatibility is confirmed. However, the termination style difference (solder vs. press-fit) requires PCB design review. Press-fit termination uses mechanical insertion, while solder termination requires through-hole pads and reflow or wave soldering processes. Verify PCB pad layout and assembly capability before implementation.

Q: Are there dimensional concerns with the 1843868 substitute?

A: Contact tail length differs by 0.004" (4.60mm vs. 3.40mm) and insulation height by 0.009" (7.00mm vs. 7.25mm). These variations are within standard manufacturing tolerances and do not affect standard through-hole mounting applications. Confirm clearance in your specific mechanical assembly.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory iteration. The 1843868's ROHS3 status reflects current compliance standards and supports regulatory alignment for new designs.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated at 8A (IEC/UL) and 250V (IEC) / 300V (UL). Voltage and current handling capacity are equivalent, confirming electrical interchangeability within the specified operating parameters.

Q: What is the inventory status for these parts?

A: The 1897319 (obsolete) has 942 units in stock. The 1843868 (active) has 1225 units in stock, providing superior long-term availability and supply security.
