Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897018 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 9
• Pitch: 0.150" (3.81mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Current rating (IEC): 8A
• Voltage rating (IEC): 250V
• Current rating (UL): 8A
• Voltage rating (UL): 300V
• Housing material: Polybutylene Terephthalate (PBT)
• Flammability rating: UL94 V-0
• Contact mating finish: Tin

Allowable Variations:

• Termination style (Press-Fit vs. Solder)
• Series designation (COMBICON EMC vs. COMBICON MC)
• Product status (Obsolete vs. Active)
• Packaging format
• Minor dimensional tolerances in contact tail length and insulation height
• RoHS compliance generation (RoHS vs. ROHS3)

The Phoenix Contact 1827936 qualifies as a direct substitute based on full alignment of all mandatory parameters, with termination style as the primary distinguishing feature.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1827936 is a qualified substitute for the obsolete 1897018 based on electrical and mechanical parameter equivalence. Both components maintain identical current and voltage ratings (8A/250V IEC, 8A/300V UL), housing material (PBT), and flammability classification (UL94 V-0).

The primary distinction is termination methodology: the 1897018 uses press-fit termination, while the 1827936 employs solder termination. This difference requires assessment of the target application's assembly process and PCB design. Press-fit termination eliminates solder reflow steps, whereas solder termination integrates with standard wave or reflow soldering processes.

The 1827936 carries Active product status with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the Obsolete 1897018. Minor dimensional variations in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") fall within acceptable mechanical tolerances for equivalent functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 1827936 directly replace the 1897018 in existing designs?

A: Electrical and mechanical compatibility is confirmed. The termination style difference (solder vs. press-fit) requires PCB design and assembly process alignment. If the original design uses press-fit mounting, the 1827936 requires solder-compatible PCB pads and reflow or wave soldering integration.

Q: What is the significance of the series designation change (COMBICON EMC to COMBICON MC)?

A: Series designation reflects product line evolution within Phoenix Contact's terminal block portfolio. Both series maintain identical electrical ratings, housing materials, and flammability classifications. The change does not affect functional substitution eligibility.

Q: Are there packaging differences between the 1897018 and 1827936?

A: The 1897018 is listed with unspecified packaging, while the 1827936 is supplied in Bulk packaging. Packaging format does not affect component functionality or electrical performance.

Q: How do the dimensional variations 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 manufacturing tolerances and do not require PCB redesign for equivalent mounting performance.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS compliant (1897018: RoHS Compliant; 1827936: ROHS3 Compliant), carry UL94 V-0 flammability ratings, and maintain MSL 1 (Unlimited) moisture sensitivity levels. The 1827936 includes REACH Unaffected status.

Q: Why is the 1897018 classified as Obsolete?

A: Obsolete status indicates discontinued manufacturing. The 1827936 (Active status) represents the current production equivalent within Phoenix Contact's COMBICON terminal block family.
