Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block headers is determined by strict alignment of electrical and mechanical parameters. The Phoenix Contact 1897160 can be substituted by part number 1844281 based on the following criteria:

Matching Parameters (Substitution Basis):

• Number of positions: 9
• 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
• Voltage - IEC: 250 V
• Voltage - UL: 300 V
• Contact mating finish: Tin
• Series family: COMBICON (both EMC and MC variants)

Differing Parameters (Acceptable Variations):

• Termination style: Press-Fit (1897160) vs. Solder (1844281)
• Current - IEC: 8A (1897160) vs. 12A (1844281)
• Contact tail length: 0.138" (4.60mm) vs. 0.134" (3.40mm)
• Insulation height: 0.276" (7.00mm) vs. 0.285" (7.25mm)
• Product status: Obsolete (1897160) vs. Active (1844281)
• RoHS certification: RoHS Compliant vs. ROHS3 Compliant

The substitute part 1844281 maintains full electrical and mechanical compatibility within the COMBICON terminal block family while offering higher current capacity and active product status.

Engineering Selection Recommendations

For Direct Replacement (Press-Fit Applications): The Phoenix Contact 1897160 is obsolete. When press-fit termination is required, sourcing from remaining inventory is the only option using this exact part number. The 1844281 substitute is not suitable for press-fit applications due to its solder termination design.

For New Designs or Solder-Compatible Applications: The Phoenix Contact 1844281 is the recommended substitute. This part is active in production, carries current RoHS3 compliance certification, and provides enhanced current capacity (12A IEC vs. 8A IEC). Both parts meet UL94 V-0 flammability requirements and maintain identical electrical ratings for voltage (250V IEC, 300V UL). The mechanical form factor remains compatible within the COMBICON terminal block family.

Compliance Considerations: Both parts are RoHS compliant. The 1844281 carries ROHS3 certification, representing the current regulatory standard. The 1897160 carries legacy RoHS compliance status consistent with its obsolete product classification.

Frequently Asked Questions (FAQ)

Q: Can the 1844281 directly replace the 1897160 in existing assemblies? A: Mechanical and electrical compatibility exists for applications where solder termination is acceptable. The 1844281 cannot replace the 1897160 in designs requiring press-fit termination. PCB layout modifications may be necessary due to minor differences in contact tail length (0.134" vs. 0.138") and insulation height (0.285" vs. 0.276").

Q: What is the significance of the different termination styles? A: The 1897160 uses press-fit termination, which requires specific PCB pad design and insertion tooling. The 1844281 uses solder termination, requiring standard PCB solder pads and wave or reflow soldering processes. These are fundamentally different assembly methods and are not interchangeable without PCB redesign.

Q: Are there electrical performance differences between these parts? A: Both parts maintain identical voltage ratings (250V IEC, 300V UL). The 1844281 offers higher current capacity at 12A IEC compared to the 1897160 at 8A IEC. For applications operating at or below 8A, both parts are electrically equivalent.

Q: What does the COMBICON series designation mean? A: COMBICON is the Phoenix Contact terminal block product family. The EMC variant (1897160) and MC variant (1844281) represent different series within this family, each with specific design characteristics. Both maintain compatibility within the 4.60mm pitch, 9-position, 90° right-angle header category.

Q: Is the 1844281 suitable for high-reliability applications? A: Both parts carry UL94 V-0 flammability certification and meet industrial-grade electrical specifications. The 1844281 carries current ROHS3 compliance, making it suitable for applications with active regulatory compliance requirements. Product status (Active vs. Obsolete) indicates ongoing manufacturing support for the 1844281.
