Phoenix Contact 1897801 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897801 is a 2-position terminal block header with male pins, shrouded design, and 0.150" (3.81mm) pitch in 90° right-angle through-hole configuration. This component belongs to the COMBICON EMC series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts from the active product portfolio is essential for ongoing system maintenance, repairs, and new designs requiring compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1897801 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Current rating: 8A (IEC and UL)
• Voltage rating: 250V (IEC) / 300V (UL)

Mechanical Compatibility:

• Number of positions: 2
• Pitch: 0.150" (3.81mm)
• Header orientation: 90° right angle
• Mounting type: Through hole
• Shrouded design (4 side)
• Male pin configuration

Material & Compliance:

• Housing material: Polybutylene Terephthalate (PBT)
• Flammability rating: UL94 V-0
• Contact finish: Tin
• RoHS compliance status

The substitute part Phoenix Contact 1803277 meets all these critical parameters. Differences in termination style (press-fit vs. solder), series designation (COMBICON EMC vs. COMBICON MC), product status (obsolete vs. active), and minor dimensional variations in contact tail length and insulation height do not affect functional interchangeability in applications where the 1897801 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1803277 is the appropriate substitute for the obsolete 1897801 based on the following factors:

Product Status & Availability: The 1897801 is classified as obsolete, making the 1803277 the active equivalent from Phoenix Contact's current COMBICON product line. The 1803277 maintains full electrical and mechanical compatibility while offering improved long-term availability and supply chain continuity.

Compliance & Certification: Both parts meet UL94 V-0 flammability requirements and maintain RoHS compliance. The 1803277 carries ROHS3 certification, representing the current regulatory standard. Both components are rated for identical electrical parameters (8A at 250V IEC / 300V UL) and share the same MSL classification.

Functional Equivalence: The 2-position, 0.150" pitch, 90° right-angle through-hole configuration is identical between both parts. The shrouded 4-side male pin design ensures mechanical interchangeability in existing PCB layouts and connector assemblies.

Termination Consideration: The primary difference is termination style: the 1897801 uses press-fit termination, while the 1803277 uses solder termination. This difference requires evaluation based on the specific assembly process and PCB design. Press-fit termination offers automated assembly advantages, while solder termination provides traditional wave or reflow soldering compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1803277 directly replace the 1897801 in existing designs?

A: Yes, the 1803277 is mechanically and electrically equivalent. Both parts share identical pitch (0.150"), position count (2), orientation (90° right angle), and electrical ratings (8A, 250V IEC / 300V UL). The primary consideration is termination method: the 1897801 uses press-fit while the 1803277 uses solder termination. PCB design and assembly process compatibility must be evaluated accordingly.

Q: What is the significance of the different termination styles?

A: Press-fit termination (1897801) allows automated insertion without soldering, reducing thermal stress on components. Solder termination (1803277) requires wave or reflow soldering and is compatible with traditional PCB assembly processes. Selection depends on manufacturing capability and design requirements.

Q: Are there any dimensional differences that affect PCB layout?

A: Minor dimensional variations exist: contact tail length differs by 0.004" (0.10mm) and insulation height by 0.009" (0.25mm). These differences are within typical PCB design tolerances and do not affect footprint compatibility for standard through-hole applications.

Q: Why is the 1897801 obsolete?

A: The 1897801 belongs to the COMBICON EMC series, which has been superseded by the COMBICON MC series (represented by the 1803277). Phoenix Contact has transitioned to the newer product line, making the 1803277 the current active equivalent.

Q: Are both parts RoHS compliant?

A: Yes. The 1897801 is RoHS Compliant, and the 1803277 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions. ROHS3 represents the current regulatory standard.

Q: What is the inventory status of these parts?

A: The 1897801 has 1013 pieces in stock (new original), while the 1803277 has 7532 pieces in stock (new original, bulk packaging). The 1803277 offers superior long-term availability as an active product.
