Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1700409 is determined by strict alignment of the following critical parameters:

• Position count and pitch: Must maintain 3 positions at 0.138" (4.60mm) spacing to ensure PCB footprint compatibility
• Header type and shrouding: Must be male pins with 4-side shrouding for mechanical and electrical safety equivalence
• Mounting technology: Through-hole mounting is required for board integration compatibility
• Electrical ratings: Current and voltage ratings must meet or exceed 8A at 160V (IEC) and 300V (UL) specifications
• Contact finish: Tin plating ensures equivalent solderability and corrosion resistance
• Insulation height: 0.362" (9.20mm) dimension must be maintained for assembly clearance

The Phoenix Contact 1729205 qualifies as a direct substitute based on these parameters. The primary difference is termination style: the 1700409 uses press-fit termination, while the 1729205 employs solder termination. Both achieve equivalent electrical and mechanical performance within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1729205 is the qualified substitute for the obsolete 1700409. Selection between these parts depends on assembly process requirements:

Phoenix Contact 1700409: Press-fit termination technology eliminates soldering requirements, reducing thermal stress on PCB substrates and enabling automated assembly without reflow processes. This part is obsolete and should be replaced in new designs.

Phoenix Contact 1729205: Solder termination provides active product status with ongoing manufacturer support and RoHS compliance certification. This part is recommended for all new applications and as a replacement in existing systems where assembly process compatibility permits solder-based termination.

Both parts maintain identical electrical ratings, mechanical dimensions, and shrouding configuration. The contact tail length difference (0.150" versus 0.134") is within typical PCB design tolerances for through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the 1729205 replace the 1700409 in existing assemblies? A: Yes, provided the assembly process can accommodate solder termination. The 1729205 maintains identical pitch, position count, shrouding, and electrical ratings. Verify PCB pad design compatibility with the 0.134" contact tail length of the 1729205.

Q: What is the primary difference between these parts? A: Termination technology differs: the 1700409 uses press-fit termination while the 1729205 uses solder termination. Both achieve equivalent electrical performance and mechanical fit within the specified parameter range.

Q: Is the 1729205 RoHS compliant? A: Yes, the 1729205 is RoHS compliant. RoHS status for the 1700409 was not specified in available documentation.

Q: Are there any dimensional incompatibilities? A: The contact tail length differs by 0.016" (0.41mm). Verify PCB through-hole depth and pad design accommodate the 1729205's 0.134" tail length. Pitch, insulation height, and overall shroud dimensions are identical.

Q: What electrical parameters must be verified for substitution? A: Both parts are rated 8A at 160V (IEC) and 300V (UL). Verify your application does not exceed these ratings. Both maintain tin contact finish and identical voltage/current specifications.

Q: Why is the 1700409 listed as obsolete? A: The 1700409 is obsolete per Phoenix Contact product status. The 1729205 is the active equivalent and should be used for all new designs and system replacements.
