Phoenix Contact 1897212 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897212 is a 14-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 compatible substitute parts essential for ongoing system maintenance and new design implementations.

Terminal block headers of this configuration are used in industrial control systems, power distribution modules, and signal interconnection applications where reliable press-fit termination and compact form factors are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897212 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Number of positions: 14
• Pitch: 0.138" (4.60mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Housing material: Polybutylene Terephthalate (PBT)
• Material flammability rating: UL94 V-0
• Contact mating finish: Tin

Allowable Variations:

• Termination style: Press-Fit or Solder (both provide mechanical and electrical continuity)
• Current rating: Substitute may exceed minimum IEC/UL current requirements
• Contact tail length and insulation height: Minor dimensional variations within manufacturing tolerance
• Product status: Active status preferred for long-term availability
• RoHS compliance level: ROHS3 acceptable as superset of RoHS Compliant

The Phoenix Contact 1844333 meets all mandatory matching criteria and represents a direct functional substitute with enhanced current capacity and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844333 is a qualified substitute for the 1897212 based on the following factors:

Functional Compatibility: Both components share identical position count, pitch, orientation, shrouding configuration, and mounting methodology. The 14-position, 4.60mm pitch, 90° right-angle through-hole header form factor is preserved across both parts.

Electrical Performance: The 1844333 provides equal or superior electrical ratings. While the main part is rated at 8A (IEC), the substitute delivers 12A (IEC) capacity, exceeding the original specification. Voltage ratings remain equivalent at 250V (IEC) and 300V (UL).

Termination Consideration: The primary difference is termination method. The 1897212 uses press-fit termination; the 1844333 uses solder termination. Both methods provide reliable electrical and mechanical connections. Selection depends on assembly process capability and design requirements.

Compliance and Availability: The 1844333 holds active product status with ROHS3 compliance, ensuring long-term supply chain availability and regulatory alignment. The 1897212 is obsolete, making the 1844333 the appropriate forward-looking choice for new designs and ongoing production.

Dimensional Tolerance: Minor variations in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") fall within acceptable mechanical tolerances for PCB mounting and connector mating applications.

Frequently Asked Questions (FAQ)

Q: Can the 1844333 directly replace the 1897212 in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for the 14-position, 4.60mm pitch configuration. The primary consideration is termination method: the 1897212 uses press-fit termination while the 1844333 uses solder termination. If the PCB design accommodates solder termination, direct substitution is feasible. Press-fit tooling is not required for the 1844333.

Q: What is the significance of the different series designations (COMBICON EMC vs. COMBICON MC)?

A: Series designation reflects product line evolution within Phoenix Contact's terminal block portfolio. Both series maintain identical electrical and mechanical specifications for this 14-position, 4.60mm pitch configuration. The COMBICON MC series (1844333) represents the current production line with active status.

Q: Are there dimensional differences that affect PCB layout?

A: Contact tail length differs by 0.004" (0.10mm) and insulation height by 0.009" (0.25mm). These variations are within standard PCB design tolerances for through-hole component mounting. Verify PCB footprint clearances if space constraints exist.

Q: Does the higher current rating (12A vs. 8A) of the 1844333 affect compatibility?

A: No. Higher current capacity is a superset specification that maintains backward compatibility. The 1844333 can safely handle applications designed for 8A operation. Current rating selection should be based on actual circuit requirements, not component capability alone.

Q: What packaging is available for the 1844333?

A: The 1844333 is supplied in bulk packaging, suitable for production assembly environments. Confirm packaging requirements with procurement specifications.

Q: Are both parts RoHS compliant?

A: Yes. The 1897212 is RoHS Compliant; the 1844333 is ROHS3 Compliant. ROHS3 represents an updated compliance standard and is acceptable for applications requiring RoHS certification.
