Phoenix Contact 1805656 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1805656 is a 5-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 system maintenance and new design implementations. The part operates at 12A (IEC) and 600V (IEC), providing reliable electrical connectivity in industrial control and distribution applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1805656 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 5 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Type & Orientation: Vertical through-hole male pin headers are required to match the original mounting configuration and signal routing.
• Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements. The substitute part 1933215 operates at reduced IEC voltage (400V vs. 600V) but provides higher current capacity under UL standards (16A at 300V).
• Housing & Contact Materials: Polyamide nylon construction with tin-plated contacts ensures consistent performance and environmental resistance.
• Compliance & Certifications: RoHS compliance and UL94 V-0 flammability rating are maintained across substitute options.

The primary distinction between the main part and substitute is the shroud configuration: the 1805656 features a partial shroud, while the 1933215 is unshrouded. This affects mechanical protection and insertion force characteristics but does not prevent functional substitution in applications where shroud presence is not a design requirement.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1933215 is the primary substitute for the obsolete 1805656. Both components are manufactured by Phoenix Contact within the COMBICON PST series and share identical position count, pitch, orientation, and mounting configuration.

Compliance Advantage: The 1933215 carries active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment for new designs and long-term production support.

Electrical Consideration: The 1933215 operates at 400V IEC (versus 600V for the main part). Applications requiring 600V IEC operation must verify that the substitute's 400V rating is acceptable for the intended circuit. Under UL standards, the 1933215 provides 16A at 300V, exceeding the IEC current specification of 12A.

Mechanical Difference: The removal of the partial shroud in the 1933215 reduces mechanical protection but does not affect electrical performance. PCB layout and connector mating force characteristics may differ slightly due to the 0.004" (0.10mm) reduction in contact tail length (4.60mm versus 3.60mm).

Recommendation Basis: Selection should be based on voltage requirement verification and shroud necessity for the application. The active status and enhanced compliance of the 1933215 make it the preferred choice for new implementations where 400V IEC operation is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 1933215 directly replace the 1805656 on existing PCBs?

A: Mechanical compatibility is maintained due to identical pitch (5.00mm), position count (5), and through-hole mounting configuration. The 0.004" difference in contact tail length is within typical PCB tolerance ranges. Verify that the unshrouded design does not conflict with board layout or connector specifications.

Q: What is the primary difference between these two parts?

A: The 1805656 features a partial shroud for mechanical protection, while the 1933215 is unshrouded. Both maintain identical electrical specifications at 12A IEC and share the same COMBICON PST series design.

Q: Is the 1933215 suitable for 600V applications?

A: The 1933215 is rated for 400V IEC maximum. Applications requiring 600V operation must use the original 1805656 or identify alternative components with matching voltage specifications. Exceeding the rated voltage will compromise component reliability.

Q: Are there compliance differences between the two parts?

A: The 1805656 is RoHS Compliant, while the 1933215 is ROHS3 Compliant. Both maintain UL94 V-0 flammability rating. The ROHS3 designation on the 1933215 reflects current regulatory standards and ensures ongoing market availability.

Q: How do the contact tail lengths affect PCB design?

A: The 1805656 has a 3.60mm contact tail, while the 1933215 has a 4.60mm tail. This 0.10mm difference is typically accommodated within standard PCB through-hole tolerances. Verify solder joint depth and via placement if precision is critical for your application.

Q: Why is the 1805656 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1933215 serves as the active replacement within the COMBICON PST series, providing equivalent functionality with current manufacturing support and regulatory compliance.
