Phoenix Contact 1805672 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1805672 is a 7-position terminal block header with male pins and partial shroud, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The partial shroud design provides mechanical guidance while maintaining accessibility for wire termination.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1933231 qualifies as a substitute for the 1805672 based on the following matching parameters:

• Identical number of positions (7)
• Identical pitch spacing (0.197" / 5.00mm)
• Identical header orientation (vertical)
• Identical termination style (solder)
• Identical mounting type (through hole)
• Identical series designation (COMBICON PST)
• Identical housing material (Polyamide/Nylon)
• Identical contact mating finish (tin)
• Identical flammability rating (UL94 V-0)

The primary design difference is the shroud configuration: the 1933231 features an unshrouded design compared to the partial shroud of the 1805672. This distinction affects mechanical guidance during assembly but does not impact electrical compatibility or functional performance in applications where shrouding is not a critical requirement.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1933231 is the designated substitute for the obsolete 1805672. The 1933231 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.

Both parts meet UL94 V-0 flammability requirements and maintain RoHS compliance. The 1933231 carries ROHS3 certification, representing current regulatory alignment. The unshrouded design of the 1933231 provides equivalent electrical and mechanical performance for applications where partial shrouding is not a design constraint.

The IEC voltage rating of the 1933231 (400V) is lower than the 1805672 (600V). Applications requiring the full 600V IEC rating must evaluate whether the 1933231 meets system voltage requirements. The UL ratings provided for the 1933231 (16A at 300V) establish alternative compliance pathways for systems designed to UL standards.

Frequently Asked Questions (FAQ)

Q: Can the 1933231 directly replace the 1805672 in existing designs?

A: The 1933231 is electrically and mechanically compatible for applications where the partial shroud of the 1805672 is not a functional requirement. The unshrouded design maintains identical pitch, position count, and termination characteristics. Verify that your application voltage requirements align with the 1933231 specifications.

Q: What is the significance of the shroud difference?

A: The partial shroud on the 1805672 provides mechanical guidance during mating operations. The unshrouded 1933231 eliminates this feature but maintains full electrical connectivity and contact integrity. Shroud presence does not affect electrical performance.

Q: Are there voltage rating differences I should consider?

A: The 1805672 carries a 600V IEC rating, while the 1933231 is rated at 400V IEC. For applications operating at voltages between 400V and 600V, the 1805672 specifications must be maintained or system voltage requirements must be reduced to 400V maximum.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. Both parts meet hazardous substance restrictions applicable to their respective certification dates.

Q: Are the contact tail lengths functionally different?

A: The contact tail length difference (0.142" versus 0.138") is 0.004" (0.10mm). This minor variation does not affect electrical performance or standard PCB through-hole mounting applications.
