Phoenix Contact 1897348 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897348 is a 12-position terminal block header with male pins, shrouded design, and 4.6mm pitch in a 90° right-angle through-hole configuration. 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 RoHS compliance and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1843897 qualifies as a direct substitute for the 1897348 based on the following critical parameters:

Matching Parameters:

• 12-position configuration with identical pitch (0.138" / 4.60mm)
• 90° right-angle through-hole mounting orientation
• Male pins with 4-side shrouded design
• Identical electrical ratings: 8A (IEC/UL), 250V (IEC), 300V (UL)
• Same housing material (PBT) and flammability rating (UL94 V-0)
• Tin contact mating finish
• Same connector category and functional purpose

Differentiating Parameters:

• Termination style: 1897348 uses press-fit; 1843897 uses solder
• Series designation: 1897348 belongs to COMBICON EMC; 1843897 belongs to COMBICON MC
• Product status: 1897348 is obsolete; 1843897 is active
• Minor dimensional variations in contact tail length and insulation height
• Compliance certifications: 1897348 is RoHS Compliant; 1843897 is ROHS3 Compliant with REACH Unaffected status

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843897 is the designated substitute for the obsolete 1897348 model. Both components maintain identical electrical performance specifications and mechanical compatibility for 12-position, 4.6mm pitch terminal block applications.

The primary distinction lies in termination methodology: the 1897348 employs press-fit termination, while the 1843897 uses solder termination. This difference requires corresponding changes to PCB design and assembly processes. The 1843897's active product status and ROHS3 compliance provide enhanced supply chain availability and regulatory alignment for new designs.

Minor dimensional variations in contact tail length (0.138" versus 0.134") and insulation height (0.276" versus 0.285") fall within acceptable mechanical tolerances for standard through-hole mounting applications and do not impact functional interchangeability in typical circuit configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1843897 directly replace the 1897348 in existing assemblies?

A: Electrical and mechanical compatibility is confirmed. However, the termination method differs: 1897348 uses press-fit while 1843897 requires solder termination. Existing press-fit PCB footprints must be adapted for solder-based assembly.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is based on matching position count (12), pitch (4.60mm), orientation (90° right-angle), connector type (male pins, shrouded), electrical ratings (8A/250V IEC, 8A/300V UL), housing material (PBT), and flammability rating (UL94 V-0).

Q: Are there compliance differences between these parts?

A: The 1897348 carries RoHS Compliant status, while the 1843897 is ROHS3 Compliant with REACH Unaffected designation. Both meet environmental and regulatory requirements; the 1843897 reflects current compliance standards.

Q: Do the dimensional differences affect PCB layout?

A: Contact tail length and insulation height variations are minor (0.004" and 0.009" respectively) and remain within standard through-hole mounting tolerances. PCB footprints designed for the 1897348 accommodate the 1843897 without modification.

Q: Why is the 1897348 listed as obsolete?

A: The 1897348 belongs to the COMBICON EMC series, which has been superseded by the active COMBICON MC series represented by the 1843897. Phoenix Contact maintains the 1843897 as the current production equivalent.
