Phoenix Contact 1805685 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1805685 is an 8-position terminal block header with male pins and partial shroud, designed for 0.197" (5.00mm) pitch vertical through-hole applications. 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) with solder termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1805685 is determined by the following critical parameters:

• Position Count & Pitch: 8 positions at 0.197" (5.00mm) spacing (non-negotiable for PCB compatibility)
• Header Type & Orientation: Male pins, vertical through-hole configuration
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
• Termination Method: Solder termination required for through-hole assembly
• Housing Material & Flammability: Polyamide construction with UL94 V-0 rating
• RoHS Compliance: Required for modern supply chain acceptance

The Phoenix Contact 1933244 qualifies as a direct substitute based on matching position count, pitch, orientation, termination style, and mounting type. The primary design difference is the transition from partial shroud to unshrouded configuration, which does not affect electrical or mechanical compatibility in applications where shrouding is not a functional requirement.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1933244 is the designated substitute for the obsolete 1805685 based on the following engineering criteria:

Compliance & Availability: The 1933244 maintains active product status with established supply chain availability (4824 pcs in stock versus 642 pcs for the obsolete part). Both components carry UL94 V-0 flammability certification and meet RoHS requirements, with the 1933244 offering ROHS3 compliance for enhanced regulatory alignment.

Electrical Compatibility: The 1933244 meets the IEC current requirement (12A) and exceeds UL current specifications (16A versus unspecified for the main part). The IEC voltage rating of 400V is lower than the 1805685 (600V), requiring application-level voltage verification. The 1933244 provides UL voltage ratings (300V) not specified for the original part.

Mechanical Compatibility: Both components share identical position count (8), pitch (5.00mm), orientation (vertical), and termination method (solder through-hole). The contact tail length difference (0.138" versus 0.142") is within typical PCB design tolerances. The primary design distinction is the unshrouded configuration of the 1933244 versus the partial shroud of the 1805685.

Design Consideration: Applications requiring partial shroud functionality for mechanical guidance or contact protection must evaluate whether the unshrouded design of the 1933244 introduces compatibility issues specific to the end-use environment.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1933244 directly replace the 1805685 on existing PCBs?

A: Yes, for applications where the partial shroud is not a functional requirement. Both components share identical position count, pitch, vertical orientation, and solder termination. The 0.004" (0.10mm) difference in contact tail length falls within standard PCB design tolerances. Verify that your application does not depend on the shroud for mechanical alignment or contact protection.

Q: What is the voltage rating difference between these parts?

A: The 1805685 is rated at 600V (IEC), while the 1933244 is rated at 400V (IEC). For applications operating above 400V, the 1933244 does not meet the original voltage specification. Confirm your system voltage requirements before substitution.

Q: Why is the 1805685 obsolete?

A: The 1805685 is classified as obsolete by Phoenix Contact. The 1933244 represents the active product line continuation within the COMBICON PST series, offering improved supply chain availability and current compliance certifications.

Q: Are there packaging differences between these parts?

A: The 1805685 packaging is listed as unspecified, while the 1933244 is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts meet RoHS requirements?

A: Yes. The 1805685 is RoHS Compliant, and the 1933244 is ROHS3 Compliant, meeting current regulatory standards for hazardous substance restrictions.

Q: What is the current rating difference?

A: Both parts are rated at 12A under IEC standards. The 1933244 additionally provides a UL rating of 16A, which is not specified for the 1805685. For UL-regulated applications, the 1933244 offers documented current capacity.
