Phoenix Contact 1897351 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897351 is a 13-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 suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL), with press-fit termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897351 is determined by the following critical parameters:

Electrical Compatibility:

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

Mechanical Compatibility:

• Number of positions: 13
• Pitch: 0.138" (4.60mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole

Material & Compliance:

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

The substitute part Phoenix Contact 1843907 maintains all critical electrical and mechanical parameters. The primary difference is the termination style (solder versus press-fit) and minor dimensional variations in contact tail length and insulation height, which do not affect functional substitution in applications designed for the 1897351.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843907 is a direct functional substitute for the obsolete 1897351 based on matching electrical ratings, mechanical dimensions, and compliance certifications. Both components maintain 8A current capacity, 250V (IEC) / 300V (UL) voltage ratings, and UL94 V-0 flammability classification.

The 1843907 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The termination method difference (solder versus press-fit) requires PCB design consideration but does not affect electrical or mechanical compatibility. Minor dimensional variations in contact tail length (0.004" difference) and insulation height (0.009" difference) are within acceptable tolerances for standard through-hole applications.

Both parts are RoHS compliant and carry identical electrical certifications, making the 1843907 suitable for direct replacement in applications originally specified for the 1897351.

Frequently Asked Questions (FAQ)

Q: Can the 1843907 directly replace the 1897351 on existing PCBs?

A: The 1843907 is mechanically and electrically compatible with the 1897351. The primary consideration is termination method: the 1897351 uses press-fit termination while the 1843907 uses solder termination. If the PCB is designed for press-fit mounting, solder termination requires design modification. If the PCB supports solder termination, direct replacement is feasible.

Q: What is the significance of the different series designations (COMBICON EMC vs. COMBICON MC)?

A: Both series are Phoenix Contact COMBICON terminal block families with identical electrical and mechanical specifications for this 13-position, 4.60mm pitch configuration. The series designation reflects product line organization but does not affect functional compatibility.

Q: Are there any compliance or certification differences between these parts?

A: Both the 1897351 and 1843907 are RoHS compliant, UL94 V-0 rated, and carry identical IEC and UL electrical certifications. No compliance differences exist between the two parts.

Q: Why is the 1897351 listed as obsolete?

A: The 1897351 has been discontinued by Phoenix Contact. The 1843907 represents the active product line continuation with equivalent functionality and specifications.

Q: What are the dimensional tolerances for the contact tail length and insulation height variations?

A: The contact tail length differs by 0.004" (0.10mm) and insulation height by 0.009" (0.25mm). These variations are within standard manufacturing tolerances for terminal block headers and do not affect PCB mounting or electrical performance in standard applications.
