Phoenix Contact 1900044 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1900044 is a 22-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1900044 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 22
• Pitch: 0.197" (5.00mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting Type: Through Hole
• Current - IEC: 12A minimum
• Voltage - IEC: 400V minimum
• Current - UL: 15A minimum
• Voltage - UL: 300V minimum
• Material Flammability Rating: UL94 V-0
• RoHS Status: RoHS Compliant

Allowable Variations:

• Termination Style: Press-Fit or Solder acceptable
• Housing Material: PBT, Polyamide (PA/Nylon), or Liquid Crystal Polymer (LCP)
• Color: Green or Black
• Contact Tail Length: Variation permitted within mechanical constraints
• Insulation Height: Minor variation acceptable (±0.02")
• Series designation: Different series acceptable if electrical/mechanical parameters align
• Product Status: Active status preferred for obsolete parts

The two identified substitutes meet these criteria while offering active product status and alternative termination technologies.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1757666 (COMBICON MSTBA Series)

Part 1757666 maintains electrical equivalence with the 1900044 across all critical IEC and UL parameters. The primary distinction is termination technology: solder termination replaces press-fit. Housing material transitions from PBT to polyamide (PA/Nylon), both meeting UL94 V-0 flammability requirements. Contact tail length reduction from 0.165" to 0.138" requires PCB layout verification for through-hole depth compatibility. Active product status ensures long-term availability. Green color matches the original specification.

Phoenix Contact 1836544 (COMBICON CCA Series)

Part 1836544 provides electrical substitution with enhanced current capacity (16A UL rating versus 15A). IEC voltage rating decreases from 400V to 320V, requiring application voltage confirmation. Solder termination and liquid crystal polymer (LCP) housing offer superior thermal and chemical resistance compared to PBT. Operating temperature specification (-40°C to 100°C) provides defined thermal operating range. Significant contact tail length reduction (0.079" versus 0.165") necessitates PCB design review. Black color differs from original green specification. Active product status supports long-term procurement.

Both substitutes maintain 22-position configuration, 5.00mm pitch, 90° right-angle orientation, through-hole mounting, and RoHS compliance. Selection between substitutes depends on termination process capability (solder versus press-fit), thermal operating requirements, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1757666 directly replace 1900044 in existing designs?

A: Electrical parameters align across IEC and UL ratings. Termination method changes from press-fit to solder, requiring assembly process modification. Contact tail length reduction (0.165" to 0.138") must be verified against PCB through-hole depth specifications. Housing material change from PBT to polyamide (PA/Nylon) maintains UL94 V-0 compliance.

Q: What are the key differences between 1757666 and 1836544?

A: Both use solder termination. 1757666 maintains 400V IEC rating and green color with polyamide housing. 1836544 offers higher UL current rating (16A), defined operating temperature range (-40°C to 100°C), and LCP housing with superior thermal properties, but reduces IEC voltage to 320V and changes color to black. Contact tail length differs significantly (0.138" versus 0.079").

Q: Is the voltage rating reduction in 1836544 (320V IEC versus 400V IEC) acceptable?

A: Acceptability depends on application voltage requirements. If system operates at or below 320V IEC, 1836544 is suitable. If application requires 400V IEC operation, 1757666 is the appropriate substitute.

Q: How does housing material affect component performance?

A: All three materials (PBT, polyamide, LCP) meet UL94 V-0 flammability requirements. Polyamide (PA/Nylon) in 1757666 and liquid crystal polymer (LCP) in 1836544 provide different thermal and chemical resistance profiles. LCP offers superior high-temperature stability. Material selection should align with environmental exposure and thermal operating conditions.

Q: Are there packaging differences between these parts?

A: 1900044 is supplied in unspecified packaging with 907 pieces in stock. 1757666 and 1836544 are supplied in bulk packaging with 1000 and 657 pieces in stock respectively. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the impact of contact tail length variation?

A: Contact tail length determines insertion depth into PCB through-holes. 1900044 specifies 0.165" (4.19mm), 1757666 specifies 0.138" (4.60mm), and 1836544 specifies 0.079" (2.00mm). PCB design must accommodate the selected substitute's tail length to ensure proper electrical connection and mechanical retention.
