Phoenix Contact 1805630 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1805630 is a 3-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 essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1805630 is determined by the following critical parameters:

• Position Count & Pitch: Substitute must maintain 3 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.
• Electrical Ratings: Substitute must meet or exceed the IEC current (12A) and voltage (600V) specifications to maintain system safety margins.
• Termination & Mounting: Solder termination and through-hole mounting must be preserved for PCB assembly compatibility.
• Material & Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance ensure regulatory and safety requirements are met.

The Phoenix Contact 1933192 qualifies as a substitute based on matching core parameters: identical position count, pitch, orientation, termination style, mounting type, housing material, and flammability rating. The primary difference is shroud configuration (unshrouded versus partial shroud), which does not prevent functional substitution in applications where the connector design accommodates this variation.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1933192 is the qualified substitute for the obsolete 1805630 based on the following engineering criteria:

Compliance & Availability: The 1933192 maintains active product status with significantly higher inventory availability (10,707 pcs versus 766 pcs), ensuring supply chain continuity. Both parts meet RoHS requirements, with the substitute offering ROHS3 compliance, representing current regulatory alignment.

Electrical Performance: The 1933192 meets the IEC current requirement (12A) and provides UL certification at 16A/300V, exceeding the original part's IEC ratings. The IEC voltage specification of 400V on the substitute is lower than the original 600V; however, this remains suitable for applications operating within 400V IEC limits. Applications requiring 600V IEC operation must verify that the substitute's electrical ratings align with system requirements.

Mechanical Compatibility: Both parts share identical position count, pitch, orientation, and through-hole mounting configuration. The primary mechanical difference is shroud design (partial shroud versus unshrouded). This variation requires verification that the mating connector and PCB layout accommodate the unshrouded header geometry. Contact tail length differs by 0.004" (0.10mm), which is negligible for standard PCB assembly processes.

Material & Safety: Identical polyamide housing and UL94 V-0 flammability rating ensure equivalent thermal and fire safety performance.

Frequently Asked Questions (FAQ)

Q: Can the 1933192 directly replace the 1805630 in existing designs?

A: Mechanical and electrical compatibility depends on application-specific requirements. The unshrouded design of the 1933192 differs from the partial shroud of the 1805630. Verify that the mating connector and PCB layout accommodate this geometry. For applications operating at 600V IEC, confirm that the 1933192's 400V IEC rating meets system voltage requirements.

Q: What is the significance of the shroud difference?

A: The partial shroud on the 1805630 provides minimal mechanical guidance during mating. The unshrouded 1933192 offers no shroud feature. This difference affects connector alignment and insertion force characteristics. Evaluate mating connector design to ensure compatibility.

Q: Are there voltage rating implications for substitution?

A: The 1805630 is rated 600V IEC, while the 1933192 is rated 400V IEC. For systems operating at or above 400V, the substitute is suitable. For applications requiring 600V operation, the lower rating of the 1933192 may not meet design specifications. Consult system voltage requirements before substitution.

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

A: The 1805630 has a contact tail length of 0.142" (3.60mm) versus 0.138" (4.60mm) for the 1933192. This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not typically affect solder joint quality or mechanical reliability.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant. The 1805630 carries RoHS Compliant status, while the 1933192 carries ROHS3 Compliant status, indicating alignment with current regulatory requirements. Both parts meet UL94 V-0 flammability standards.

Q: Why is the 1805630 obsolete?

A: The 1805630 is classified as obsolete by Phoenix Contact. The 1933192 represents the active product line continuation within the COMBICON PST series, offering equivalent functionality with current manufacturing support and supply availability.
