Phoenix Contact 1900183 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1900183 is a 13-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part operates at IEC ratings of 12A/400V and UL ratings of 15A/300V, with press-fit termination and green polybutylene terephthalate (PBT) housing rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1900183 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 13 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.
• Header Type & Orientation: Substitutes must be male pin headers with 90° right-angle orientation and four-side shrouding to maintain form factor and mounting compatibility.
• Electrical Ratings: Substitute parts must meet or exceed the IEC ratings (12A/400V) and UL ratings (15A/300V) to ensure safe operation within the original design envelope.
• Mounting & Termination: Through-hole mounting is required; however, termination style (press-fit versus solder) represents a design-level substitution decision based on assembly process compatibility.
• Material & Compliance: Housing material, flammability rating (UL94 V-0), and RoHS compliance must be maintained or improved.

The two identified substitute parts meet these core criteria with variations in termination style, color, housing material, and contact tail length.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776809 (COMBICON MSTB Series)

Part 1776809 is the primary substitute for the obsolete 1900183. Both parts maintain identical electrical ratings (12A/400V IEC, 15A/300V UL), pitch, position count, and form factor. The key difference is termination style: 1776809 uses solder termination instead of press-fit. This substitution is suitable for designs where solder assembly is the standard manufacturing process. The contact tail length is shorter (0.138" versus 0.165"), which may require PCB layout verification for through-hole depth compatibility. Part 1776809 is currently in active production status with 647 units in stock.

Phoenix Contact 1836793 (COMBICON CC Series)

Part 1836793 serves as an alternative substitute with enhanced electrical performance (16A UL rating) and improved operating temperature range (-40°C to 100°C). The housing material differs (Liquid Crystal Polymer instead of PBT), offering superior thermal and chemical resistance. The contact tail length is significantly shorter (0.079" versus 0.165"), requiring careful PCB design verification. Color is black rather than green. This part is suitable for applications requiring higher current capacity or extended temperature operation. Part 1836793 is in active production with 847 units in stock.

Both substitute parts are RoHS compliant, UL94 V-0 rated, and manufactured by Phoenix Contact, ensuring design continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 1900183 with 1776809 or 1836793 without PCB modifications?

A: Mechanical compatibility depends on contact tail length. The 1900183 has a contact tail of 0.165" (4.19mm), while 1776809 has 0.138" (4.60mm) and 1836793 has 0.079" (2.00mm). If your PCB is designed for the longer tail length, shorter substitutes may not achieve proper through-hole engagement. Verify PCB hole depth and via placement before substitution.

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

A: The 1776809 differs primarily in termination style (solder versus press-fit) and contact tail length. The 1836793 offers higher UL current rating (16A), extended operating temperature range, and different housing material (LCP). Both are electrically compatible at the design's nominal operating point.

Q: Are all three parts electrically interchangeable?

A: At nominal operating conditions, yes. All three parts meet or exceed the original 12A/400V IEC and 15A/300V UL ratings. However, the 1836793 provides additional margin with 16A UL capacity. The 1776809 maintains identical electrical specifications to the original part.

Q: Does the color difference between parts affect functionality?

A: No. Color is a visual identifier only and does not affect electrical or mechanical performance. The 1900183 and 1776809 are green; the 1836793 is black. Color selection may be driven by design documentation or assembly traceability requirements.

Q: What assembly process considerations apply to these substitutes?

A: The 1900183 uses press-fit termination, which requires specialized insertion tooling. Both 1776809 and 1836793 use solder termination, compatible with standard wave or reflow soldering processes. If transitioning from press-fit to solder assembly, verify that your manufacturing process and PCB design accommodate solder joint formation and thermal cycling.

Q: Are there inventory or lead time advantages to selecting one substitute over another?

A: Both 1776809 (647 units) and 1836793 (847 units) are in active production with current stock availability. The 1900183 is obsolete with limited remaining inventory (776 units). For new designs or long-term supply assurance, either active substitute is preferable to the obsolete original part.
