Phoenix Contact 1915819 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915819 is an 18-position terminal block header with male pins, featuring a 4-side shrouded design and 0.197" (5.00mm) pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations.

The primary function of this terminal block is to provide a secure, standardized connection interface for 18 conductors in industrial control and power distribution applications. Given its obsolete status, equivalent active-production alternatives are necessary to ensure supply chain continuity and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915819 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 18
• Pitch: 0.197" (5.00mm)
• Header Orientation: Vertical
• Mounting Type: Through Hole
• Type: Header, Male Pins, Shrouded (4 Side)
• Current Rating (IEC): 12A minimum
• Voltage Rating (IEC): 320V minimum
• Voltage Rating (UL): 300V minimum
• Material Flammability Rating: UL94 V-0
• Contact Mating Finish: Tin

Allowable Variations:

• Termination Style: Press-Fit or Solder acceptable
• Housing Material: PBT or Liquid Crystal Polymer (LCP)
• Contact Tail Length: Minor variations permitted within mechanical envelope constraints
• Product Status: Active-production parts preferred for supply continuity
• Series Designation: Different COMBICON series acceptable if electrical and mechanical parameters align

The two identified substitute parts meet these criteria while offering improved availability and compliance status compared to the obsolete original component.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1777044 (COMBICON MSTBV Series)

Part 1777044 is an active-production component offering direct electrical and mechanical compatibility with the 1915819. The primary distinction is termination style: 1777044 employs solder termination rather than press-fit. This substitution is suitable for applications where solder attachment to PCBs is the standard assembly method. The component maintains identical pitch, position count, shrouding configuration, and electrical ratings (12A IEC, 400V IEC, 300V UL). Housing material remains PBT with UL94 V-0 flammability rating. Active product status ensures long-term availability and supply chain stability.

Phoenix Contact 1837527 (COMBICON CCV Series)

Part 1837527 is an active-production alternative with enhanced electrical performance and different material composition. This component features a higher UL current rating (16A versus 12A) and operates across an extended temperature range (-40°C to 100°C). The housing material is Liquid Crystal Polymer (LCP) rather than PBT, providing superior thermal and chemical resistance. Contact tail length is reduced to 0.079" (2.00mm) compared to 0.154" (3.90mm) in the original part, requiring verification of PCB pad layout compatibility. Solder termination is employed. This substitution is appropriate for applications requiring enhanced thermal performance or higher current capacity within the same voltage and position specifications.

Both substitute parts maintain the mandatory electrical ratings, shrouding configuration, and flammability compliance of the original component. Selection between 1777044 and 1837527 depends on specific assembly process requirements (solder versus press-fit preference) and thermal/current performance needs.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1777044 be used as a direct replacement for 1915819 in existing designs?

A: Yes, with assembly process modification. Both components share identical electrical ratings (12A IEC, 400V IEC, 300V UL), pitch (5.00mm), position count (18), and mechanical envelope. The primary difference is termination style: 1915819 uses press-fit while 1777044 requires solder attachment. PCB design and assembly procedures must accommodate solder termination.

Q: What is the key difference between 1777044 and 1837527?

A: Both are solder-termination alternatives to the press-fit 1915819. Part 1837527 offers higher UL current rating (16A versus 12A), extended operating temperature range (-40°C to 100°C), and LCP housing material for enhanced thermal performance. Contact tail length differs: 1837527 measures 0.079" (2.00mm) versus 0.154" (3.90mm) for 1777044. This shorter tail in 1837527 requires PCB pad layout verification.

Q: Are all three parts electrically interchangeable?

A: Yes, within their specified ratings. All three components meet or exceed the original 1915819 electrical specifications: 12A minimum current (IEC), 320V minimum voltage (IEC), and 300V voltage (UL). Part 1837527 provides additional margin with 16A UL current rating. Mechanical compatibility depends on termination style and contact tail length accommodation in the PCB design.

Q: What compliance certifications apply to the substitute parts?

A: Both 1777044 and 1837527 maintain UL94 V-0 flammability rating, matching the original 1915819. Part 1777044 carries RoHS3 compliance and REACH Unaffected status. Part 1837527 does not list these compliance designations in available documentation. Verify specific compliance requirements for your application before final selection.

Q: Why is the contact tail length different in 1837527?

A: The 0.079" (2.00mm) contact tail in 1837527 versus 0.154" (3.90mm) in 1777044 reflects different design approaches within the COMBICON CCV series. This shorter tail requires PCB pad depth and hole sizing verification to ensure proper solder joint formation and mechanical retention.

Q: Can 1915819 be repaired or refurbished given its obsolete status?

A: Component repair is not applicable to terminal blocks. The obsolete status indicates Phoenix Contact has discontinued production. Existing inventory (879 pieces noted as in stock) may be available through authorized distributors, but long-term supply cannot be guaranteed. Substitution to active-production parts (1777044 or 1837527) is recommended for new designs and ongoing maintenance requirements.
