Phoenix Contact 1805669 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1805669 is a 6-position terminal block header with male pins and partial shroud, designed for 0.197" (5.00mm) pitch vertical through-hole applications. This component operates at 12A (IEC) and 600V (IEC) with tin-plated contacts and polyamide housing rated UL94 V-0. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1805669 is determined by the following critical parameters:

• Position Count & Pitch: 6 positions at 0.197" (5.00mm) spacing
• Header Configuration: Male pins with vertical through-hole mounting
• Electrical Ratings: Minimum 12A current capacity and 400V voltage rating (IEC)
• Termination & Housing: Solder termination with polyamide construction rated UL94 V-0
• Contact Finish: Tin-plated mating surfaces
• Compliance: RoHS compliance required

The Phoenix Contact 1933228 qualifies as a direct substitute based on these parameters. Both components share identical position count, pitch, orientation, termination method, and housing material. The primary distinction is the shroud configuration: the 1805669 features a partial shroud, while the 1933228 is unshrouded. This difference does not prevent functional substitution in applications where the connector geometry permits unshrouded operation.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1933228 is the qualified substitute for the obsolete 1805669. Selection should be based on the following factors:

Product Status: The 1933228 maintains active product status with Phoenix Contact, ensuring continued availability and supply chain stability compared to the obsolete 1805669.

Compliance & Certifications: Both components meet RoHS requirements. The 1933228 carries ROHS3 compliance, representing current regulatory alignment. Both maintain UL94 V-0 flammability ratings and identical electrical performance within IEC standards.

Electrical Compatibility: The 1933228 meets or exceeds the electrical requirements of the 1805669 for IEC-rated applications (12A current, 400V minimum voltage). Applications operating at the full 600V IEC rating of the 1805669 must verify that 400V IEC rating of the 1933228 is acceptable for the specific use case.

Physical Compatibility: The unshrouded configuration of the 1933228 requires verification that the PCB layout and mating connector design accommodate the absence of a partial shroud. Contact tail length differs by 0.004" (0.10mm), which may require minor PCB footprint adjustment.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1933228 directly replace the 1805669 without PCB modifications?

A: The 1933228 shares identical pitch, position count, and through-hole mounting characteristics. However, the unshrouded design and 0.004" contact tail length difference may require PCB footprint verification. Mechanical fit must be confirmed before production implementation.

Q: What is the voltage difference between these parts, and does it affect substitution?

A: The 1805669 is rated 600V (IEC) while the 1933228 is rated 400V (IEC). For applications operating below 400V, the 1933228 is fully compatible. Applications requiring 600V operation must retain the original part or identify alternative solutions.

Q: Why is the 1805669 obsolete, and what is the recommended path forward?

A: The 1805669 is classified as obsolete by Phoenix Contact. The 1933228 is the active equivalent within the COMBICON PST series. For new designs or ongoing production, the 1933228 should be specified to ensure long-term supply availability.

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

A: Both components are RoHS compliant and UL94 V-0 rated. The 1933228 carries ROHS3 certification, reflecting current regulatory standards. Both meet the same flammability and material requirements for industrial terminal block applications.

Q: What is the significance of the partial shroud versus unshrouded configuration?

A: The partial shroud on the 1805669 provides mechanical guidance during mating. The unshrouded 1933228 requires precise alignment during connector insertion. PCB layout and mating connector design must accommodate this difference.
