Phoenix Contact 1941045 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1941045 is a 6-position terminal block header with male pins, shrouded on all four sides, designed for 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The part operates at IEC ratings of 12A current and 400V voltage, with UL ratings of 12A at 300V, and is constructed from polyamide (PA) nylon housing with tin-plated contacts.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1941045 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 6 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Connector Type & Orientation: Header configuration with male pins, shrouded (4 side), vertical orientation must be preserved for proper assembly and board integration.
• Termination & Mounting: Solder termination and through-hole mounting type must remain consistent with existing PCB designs.
• Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements. The substitute part must support the electrical load specifications of the original design.
• Contact & Housing Materials: Tin-plated contacts and compatible housing materials ensure reliable electrical performance and environmental resistance.
• Compliance & Certifications: RoHS compliance status and regulatory certifications must be maintained or improved for continued market acceptance.

The Phoenix Contact 1837064 qualifies as a direct substitute based on these parameters, despite differences in product status, housing material composition, and minor dimensional variations.

Engineering Selection Recommendations

The Phoenix Contact 1837064 is the qualified substitute for the obsolete 1941045 terminal block header. Selection of the 1837064 is supported by the following engineering factors:

Product Status & Availability: The 1941045 is classified as obsolete, whereas the 1837064 maintains active product status with confirmed inventory availability (818 pcs in stock). This ensures long-term supply chain continuity and access to technical support.

Regulatory Compliance: Both parts maintain RoHS compliance. The 1837064 carries ROHS3 Compliant certification, representing current regulatory alignment. The 1837064 also carries REACH Unaffected status, providing additional environmental compliance documentation.

Electrical Performance: The 1837064 exceeds the electrical requirements of the original design. While both parts support 12A at IEC ratings, the 1837064 provides 16A at UL ratings compared to 12A for the 1941045, offering improved current capacity margin.

Mechanical Compatibility: Both parts maintain identical pitch (5.00mm), position count (6), connector type (male pins, shrouded 4-side), and mounting configuration (vertical through-hole solder). The minor dimensional differences in contact tail length (0.079" vs. 0.146") and insulation height (0.472" vs. 0.480") fall within acceptable tolerances for PCB assembly and mating connector engagement.

Material & Contact Specifications: The 1837064 uses Liquid Crystal Polymer (LCP) housing with Copper Alloy contacts, both materials providing enhanced electrical and thermal performance compared to the polyamide housing of the 1941045.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1837064 be used as a direct replacement for the 1941045 in existing designs?

A: Yes. Both parts share identical pitch (5.00mm), position count (6), connector type (male pins, shrouded 4-side), and mounting configuration (vertical through-hole). The electrical ratings of the 1837064 meet or exceed the 1941045 specifications. Minor dimensional variations in contact tail length and insulation height are within acceptable assembly tolerances.

Q: What are the key differences between these two parts?

A: The primary differences are product status (1941045 is obsolete; 1837064 is active), housing material (polyamide vs. liquid crystal polymer), contact material (unspecified vs. copper alloy), UL current rating (12A vs. 16A), and contact tail length (0.146" vs. 0.079"). These differences do not prevent functional substitution.

Q: Are there any compliance concerns with using the 1837064 as a substitute?

A: No. The 1837064 maintains RoHS3 compliance and carries REACH Unaffected status, meeting or exceeding the regulatory requirements of the 1941045. Both parts are suitable for applications requiring environmental compliance certification.

Q: Does the shorter contact tail length of the 1837064 affect PCB assembly?

A: The 1837064 contact tail length is 0.079" (2.00mm) compared to 0.146" (3.70mm) for the 1941045. This difference is within standard PCB design tolerances for through-hole solder joint formation. PCB layout verification is recommended to confirm adequate solder pad dimensions.

Q: What is the current availability of the 1837064?

A: The 1837064 is an active product with 818 pcs confirmed in stock, ensuring immediate availability for production and replacement applications.
