Phoenix Contact 1805627 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1805627 is a 2-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 design support and procurement continuity. The partial shroud design and specific electrical ratings define the functional requirements for equivalent components.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1805627 is determined by the following critical parameters:

• Pitch and Position Count: 0.197" (5.00mm) pitch with 2 positions are mandatory for mechanical and electrical compatibility
• Header Type and Orientation: Vertical through-hole male pin headers are required for PCB mounting compatibility
• Electrical Ratings: Current and voltage ratings must meet or exceed IEC 12A at 600V specifications
• Housing Material and Flammability: Polyamide (PA) construction with UL94 V-0 rating ensures thermal and safety compliance
• Termination Method: Solder termination is required for through-hole PCB assembly

The Phoenix Contact 1933189 qualifies as a substitute based on matching pitch, position count, orientation, mounting type, termination style, housing material, and flammability rating. The primary design difference is the unshrouded configuration versus the partial shroud of the original part. Electrical ratings differ: the 1933189 provides 12A at 400V (IEC) and 16A at 300V (UL), which represents a trade-off in voltage rating for increased current capacity under UL standards.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1933189 is an active product within the COMBICON PST series and serves as the functional equivalent for the obsolete 1805627. Both components share identical pitch, position count, orientation, and mounting methodology, ensuring direct PCB compatibility.

Key considerations for selection:

Shroud Configuration: The 1933189 features an unshrouded design compared to the partial shroud of the 1805627. This difference affects mechanical protection and mating interface characteristics. Applications requiring shrouded connectors must evaluate whether the unshrouded configuration meets design requirements.

Electrical Ratings: The 1805627 specifies 600V (IEC), while the 1933189 provides 400V (IEC) but offers 16A at 300V under UL standards. Applications operating at voltages exceeding 400V require verification that the substitute meets system voltage requirements.

Compliance Status: The 1933189 carries ROHS3 Compliant and REACH Unaffected certifications, providing enhanced regulatory alignment compared to the RoHS Compliant status of the 1805627. Both maintain UL94 V-0 flammability ratings.

Availability: The 1933189 is in active production with substantial inventory availability, ensuring procurement continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1933189 directly replace the 1805627 in existing designs?

A: Direct replacement is mechanically and electrically feasible for applications operating at or below 400V IEC. The unshrouded configuration of the 1933189 differs from the partial shroud of the 1805627; designs requiring shrouded connectors must evaluate this difference. Contact tail length varies by 0.004" (0.10mm), which is negligible for standard through-hole PCB applications.

Q: What is the significance of the shroud difference between these parts?

A: The partial shroud on the 1805627 provides mechanical guidance and protection during mating operations. The unshrouded 1933189 offers reduced profile and simplified assembly but lacks this protective feature. Application-specific requirements determine whether this difference impacts functionality.

Q: Are there voltage limitations when substituting the 1933189 for the 1805627?

A: The 1805627 is rated for 600V (IEC), while the 1933189 is rated for 400V (IEC). Applications requiring operation above 400V must retain the original 1805627 or identify alternative components with equivalent voltage ratings. The 1933189 supports 300V under UL standards.

Q: Do both parts use the same PCB footprint?

A: Both components share identical pitch (5.00mm), position count (2), and through-hole mounting methodology. PCB footprints are compatible. Minor differences in contact tail length (0.142" versus 0.138") do not affect standard through-hole assembly processes.

Q: What compliance certifications apply to the 1933189?

A: The 1933189 carries ROHS3 Compliant and REACH Unaffected certifications. Both the 1805627 and 1933189 maintain UL94 V-0 flammability ratings and tin contact mating finish specifications.

Q: Is the 1933189 suitable for new product designs?

A: Yes. The 1933189 is an active product in the COMBICON PST series with substantial inventory availability. It is appropriate for new designs requiring 2-position, 5.00mm pitch terminal block headers with vertical through-hole mounting, subject to voltage and shroud configuration requirements.
