Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1844304 qualifies as a functional substitute for the 1897186 based on the following critical parameters:

Matching Parameters:

• Number of positions: 11
• 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)
• Flammability rating: UL94 V-0
• Voltage rating (IEC): 250V
• Voltage rating (UL): 300V
• Contact mating finish: Tin
• RoHS compliance: Compliant

Differing Parameters:

• Termination style: 1897186 uses Press-Fit; 1844304 uses Solder
• Current rating (IEC): 1897186 rated 8A; 1844304 rated 12A
• Series designation: 1897186 is COMBICON EMC; 1844304 is COMBICON MC
• Product status: 1897186 is Obsolete; 1844304 is Active
• Contact tail length: 1897186 is 0.138" (4.60mm); 1844304 is 0.134" (3.40mm)
• Insulation height: 1897186 is 0.276" (7.00mm); 1844304 is 0.285" (7.25mm)

Parameter Comparison

Engineering Selection Recommendations

The 1844304 is an active production alternative to the obsolete 1897186. Both components meet identical electrical specifications for voltage (250V IEC / 300V UL) and share the same mechanical footprint, pitch, and connector configuration. The primary distinction is termination methodology: the 1897186 employs press-fit termination, while the 1844304 uses solder termination. This difference requires PCB design modification to accommodate solder pads instead of press-fit holes.

The 1844304 carries enhanced RoHS3 compliance and maintains higher current capacity (12A IEC versus 8A IEC), providing additional design margin. Both components are manufactured from UL94 V-0 rated PBT housing and feature identical shrouded four-side construction.

For applications currently using the 1897186, transition to the 1844304 is supported by matching electrical ratings, identical connector pitch, and active product status ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the 1844304 directly replace the 1897186 without PCB modification?

A: No. The 1897186 uses press-fit termination (requiring press-fit holes), while the 1844304 uses solder termination (requiring solder pads). PCB redesign is necessary to accommodate the different termination method.

Q: Are the electrical ratings compatible?

A: Yes. Both components operate at 250V (IEC) and 300V (UL). The 1844304 has a higher IEC current rating (12A versus 8A), which is compatible with applications designed for the 1897186's 8A specification.

Q: Do the components have identical physical dimensions?

A: The pitch (0.138" / 4.60mm) and connector configuration are identical. Minor differences exist in contact tail length (0.138" versus 0.134") and insulation height (0.276" versus 0.285"), which do not affect mechanical compatibility in standard through-hole applications.

Q: What is the significance of the product status difference?

A: The 1897186 is obsolete, meaning Phoenix Contact no longer manufactures it. The 1844304 is active production, ensuring availability for new designs and ongoing supply for maintenance applications.

Q: Are both components RoHS compliant?

A: Yes. The 1897186 is RoHS Compliant, and the 1844304 is ROHS3 Compliant, meeting current environmental regulations.
