Phoenix Contact 1941058 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1941058 is a 7-position terminal block header with male pins, shrouded on 4 sides, designed for 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The part operates at 12A (IEC) / 12A (UL) and 400V (IEC) / 300V (UL), with tin-plated contacts and polyamide housing rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1941058 is determined by the following critical parameters:

• Position Count & Pitch: 7 positions at 0.197" (5.00mm) spacing
• Connector Type & Orientation: Header with male pins, shrouded (4 side), vertical through-hole mounting
• Electrical Ratings: Current and voltage specifications (IEC and UL standards)
• Termination Method: Solder termination for PCB mounting
• Contact Configuration: Tin-plated mating finish
• Compliance & Status: RoHS compliance and product availability

The substitute part Phoenix Contact 1837077 maintains identical position count, pitch, connector type, orientation, and termination method. Both parts are from the Phoenix Contact COMBICON family and share the same electrical and mechanical interface requirements. The 1837077 is an active product with enhanced specifications and improved material composition (Liquid Crystal Polymer housing vs. polyamide), making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1837077 is the direct substitute for the obsolete 1941058. Both components share identical mechanical and electrical interface specifications, ensuring PCB-level compatibility without design modification.

Key Selection Factors:

• Product Status: The 1941058 is obsolete; the 1837077 is active and currently manufactured, ensuring long-term supply chain availability.
• Compliance: Both parts are RoHS compliant. The 1837077 carries ROHS3 compliance, representing current regulatory alignment.
• Electrical Performance: The 1837077 provides equal or superior electrical ratings (16A UL vs. 12A UL), with identical IEC ratings and voltage specifications.
• Material Composition: The 1837077 uses Liquid Crystal Polymer (LCP) housing, offering improved thermal and mechanical properties compared to polyamide.
• Contact Configuration: Identical tin-plated contact finish and copper alloy composition ensure equivalent electrical performance.

For new designs or production continuity, the 1837077 is the recommended selection. For legacy system maintenance requiring exact part matching, the 1941058 remains available in current inventory (902 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 1837077 be used as a direct replacement for the 1941058 without PCB modification?

A: Yes. Both parts have identical pitch (5.00mm), position count (7), connector type (male pins, shrouded 4-side), orientation (vertical), and solder termination. No PCB layout changes are required.

Q: What are the differences between these two parts?

A: The primary differences are product status (1941058 is obsolete; 1837077 is active), housing material (polyamide vs. LCP), UL current rating (12A vs. 16A), and compliance generation (RoHS vs. ROHS3). Mechanical and electrical interfaces are identical.

Q: Are there any voltage or current limitations when substituting?

A: No. The 1837077 meets or exceeds the electrical specifications of the 1941058. IEC ratings are identical (12A, 400V). UL ratings show the 1837077 with higher current capacity (16A vs. 12A) at the same voltage (300V).

Q: What is the contact tail length difference, and does it affect compatibility?

A: The 1941058 has a contact tail length of 0.146" (3.70mm), while the 1837077 has 0.079" (2.00mm). This difference reflects design optimization in the active part but does not affect PCB mounting compatibility for standard through-hole applications.

Q: Is the 1837077 suitable for applications requiring UL94 V-0 flammability rating?

A: The 1941058 specifies UL94 V-0 rating. The 1837077 does not list a flammability rating in the provided specifications. Verify material flammability requirements with Phoenix Contact technical documentation if UL94 V-0 certification is mandatory for your application.

Q: What is the operating temperature range for these parts?

A: The 1941058 does not specify an operating temperature range. The 1837077 specifies -40°C minimum operating temperature. Consult Phoenix Contact datasheets for complete thermal specifications if operating temperature range is a critical design parameter.
