Phoenix Contact 1897173 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897173 is a 10-position terminal block header with male pins, shrouded on four sides, featuring a 0.138" (4.60mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Terminal block headers of this specification are used in industrial control systems, power distribution modules, and signal interconnection applications where reliable press-fit termination and compact form factors are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897173 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 10
• Pitch: 0.138" (4.60mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Voltage rating (IEC): 250 V minimum
• Voltage rating (UL): 300 V minimum
• Housing material: Polybutylene Terephthalate (PBT)
• Contact mating finish: Tin
• Material flammability rating: UL94 V-0

Allowable Variation Parameters:

• Termination style: Press-Fit or Solder (both suitable for through-hole applications)
• Current rating: Equal to or greater than 8A (IEC) and 8A (UL)
• Contact tail length: Within mechanical tolerance for PCB mounting
• Insulation height: Within mechanical tolerance for board clearance
• Product status: Active or Obsolete (both available for procurement)
• RoHS compliance: RoHS Compliant or ROHS3 Compliant (both acceptable)

The Phoenix Contact 1844294 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844294 is a qualified substitute for the obsolete 1897173 based on the following engineering criteria:

Electrical Compatibility: Both components meet or exceed the required voltage (250 V IEC, 300 V UL) and current (8A IEC, 8A UL) specifications. The 1844294 provides enhanced current capacity at 12A IEC, offering additional design margin.

Mechanical Compatibility: Pin pitch (0.138" / 4.60mm), position count (10), orientation (90° right angle), and mounting type (through hole) are identical. Contact tail length and insulation height variations (0.004" and 0.009" respectively) fall within standard PCB manufacturing tolerances and do not affect functional compatibility.

Material and Safety Compliance: Both components feature identical PBT housing material, UL94 V-0 flammability rating, tin contact mating finish, and green color. The 1844294 carries ROHS3 compliance, meeting current regulatory requirements, while the 1897173 maintains RoHS compliance.

Termination Consideration: The primary difference is termination style. The 1897173 uses press-fit termination, while the 1844294 uses solder termination. This difference requires PCB design verification to confirm solder pad compatibility and thermal profile acceptance.

Product Status: The 1844294 is active in production with 1627 units in stock, ensuring long-term availability compared to the obsolete 1897173 status.

Frequently Asked Questions (FAQ)

Q: Can the 1844294 directly replace the 1897173 without PCB modification?

A: Mechanical and electrical compatibility is confirmed. However, termination style differs (solder vs. press-fit). PCB pad design must be verified to accommodate solder termination. If the original design uses press-fit holes, pad geometry and hole sizing may require adjustment.

Q: What is the impact of the 0.004" difference in contact tail length?

A: This variation (0.138" vs. 0.134") is within standard PCB manufacturing tolerance (typically ±0.010"). It does not affect electrical performance or mechanical fit in standard through-hole applications.

Q: Does the 0.009" difference in insulation height create clearance issues?

A: The 1844294 insulation height is 0.285" compared to 0.276" for the 1897173. This minimal increase does not create clearance problems in typical PCB layouts. Verify clearance only if the original design has tight vertical constraints.

Q: Why does the 1844294 have a higher current rating (12A IEC vs. 8A IEC)?

A: The 1844294 belongs to the COMBICON MC series, which features enhanced current capacity. This provides additional design margin and does not create compatibility issues. The component remains suitable for 8A applications.

Q: Are there any compliance or certification differences?

A: Both components meet UL94 V-0 flammability requirements and tin contact mating finish specifications. The 1844294 carries ROHS3 compliance, which supersedes the RoHS compliance of the 1897173. Both are acceptable for current procurement.

Q: What is the availability difference between these parts?

A: The 1897173 is obsolete with 938 units in stock. The 1844294 is active in production with 1627 units available, ensuring continued supply for future requirements and design revisions.
