Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897115 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4
• Pitch: 0.138" (4.6mm)
• Header Orientation: 90°, Right Angle
• Mounting Type: Through Hole
• Type: Header, Male Pins, Shrouded (4 Side)
• Housing Material: Polybutylene Terephthalate (PBT)
• Material Flammability Rating: UL94 V-0

Electrical Compatibility Parameters:

• Current Rating: Minimum 8A (IEC)
• Voltage Rating: Minimum 250V (IEC) and 300V (UL)

Allowable Variations:

• Termination Style: Press-Fit or Solder acceptable
• Contact Tail Length: Minor dimensional tolerance (±0.004")
• Insulation Height: Minor dimensional tolerance (±0.009")
• Series designation: Different series permitted if all electrical and mechanical parameters align
• Product Status: Active status preferred for new applications; obsolete acceptable for legacy replacement

The Phoenix Contact 1844236 qualifies as a substitute based on matching all mandatory parameters and meeting or exceeding electrical requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844236 is a qualified substitute for the 1897115 based on electrical and mechanical parameter alignment. Key selection considerations:

Advantages of 1844236:

• Active product status ensures long-term availability and supply chain continuity
• IEC current rating of 12A exceeds the 8A requirement of the original part
• ROHS3 compliance represents current regulatory standard
• Higher inventory availability (5850 pcs vs. 812 pcs) supports procurement reliability

Critical Difference - Termination Method: The 1844236 uses solder termination, whereas the 1897115 uses press-fit termination. This difference requires assembly process modification. Press-fit termination allows component insertion without soldering; solder termination requires wave or reflow soldering. System design and PCB layout must accommodate this change.

Dimensional Considerations: Contact tail length and insulation height show minor variations within acceptable mechanical tolerance ranges. Verify PCB footprint compatibility before implementation.

Compliance Status: Both parts meet UL94 V-0 flammability requirements and RoHS standards. The 1844236 carries REACH Unaffected status, confirming regulatory compliance for European applications.

Frequently Asked Questions (FAQ)

Q: Can the 1844236 be used as a direct drop-in replacement for the 1897115?

A: Electrical and mechanical compatibility is confirmed. However, the termination method differs: 1897115 uses press-fit while 1844236 requires solder termination. PCB assembly process and footprint design must be verified for compatibility. Direct mechanical interchange is possible only if the PCB layout accommodates solder pads instead of press-fit holes.

Q: What is the significance of the current rating difference (8A vs. 12A)?

A: The 1844236 provides higher current capacity (12A IEC) than the original specification (8A IEC). This represents a design margin improvement and does not create compatibility issues. The substitute can safely handle applications designed for the 1897115.

Q: Are there any voltage or flammability rating concerns?

A: No. Both parts maintain identical voltage ratings (250V IEC / 300V UL) and UL94 V-0 flammability classification. Electrical safety parameters are fully compatible.

Q: What does the contact tail length variation mean for PCB design?

A: The 1844236 contact tail is 0.004" shorter (3.4mm vs. 4.6mm). This minor difference falls within standard PCB manufacturing tolerances and does not affect solder joint integrity or mechanical stability. Verify with your PCB fabricator if this dimension is critical to your design.

Q: Why is the 1844236 preferred despite the termination method change?

A: The 1844236 is an active product with superior supply chain availability and regulatory compliance. The 1897115 is obsolete, creating long-term sourcing risk. The termination method change is a one-time assembly process adjustment that provides lasting supply security.

Q: Are both parts RoHS compliant?

A: Yes. The 1897115 is RoHS Compliant, and the 1844236 is ROHS3 Compliant. Both meet environmental and hazardous substance restrictions. The 1844236 represents current regulatory standards.
