Phoenix Contact 1911020 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1911020 is a 3-position terminal block header with male pins, featuring a shrouded 4-side design and 0.138" (4.60mm) vertical pitch. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations. The part utilizes press-fit termination technology and is rated for 8A at 250V (IEC) or 300V (UL), with UL94 V-0 flammability compliance and ROHS3 certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1911020 is determined by the following critical parameters:

Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (8A at 250V IEC / 300V UL).

Mechanical Compatibility: Number of positions (3), pitch spacing (0.138" / 4.60mm), header orientation (vertical), and mounting type (through hole) must be identical.

Connector Type: Header configuration with male pins and shrouded 4-side design must be maintained.

Material and Compliance: Housing material (PBT), flammability rating (UL94 V-0), and regulatory compliance (ROHS3) must be equivalent or superior.

Termination Technology: While the original part uses press-fit termination, alternative termination methods (such as solder) are acceptable provided all other parameters remain compatible and the substitute is from the same manufacturer family.

The Phoenix Contact 1843619 qualifies as a direct substitute based on these criteria, with the primary distinction being termination method (solder vs. press-fit) and series designation (COMBICON MCV vs. COMBICON EMCV).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843619 is the qualified substitute for the obsolete 1911020 model. Both components maintain identical electrical ratings (8A / 250V IEC, 8A / 300V UL), mechanical dimensions (3 positions, 4.60mm pitch, vertical orientation), and material specifications (PBT housing, UL94 V-0 compliance).

The primary distinction is termination methodology: the original 1911020 employs press-fit technology, while the 1843619 uses solder termination. This difference requires corresponding changes to PCB design and assembly processes but does not affect electrical or mechanical compatibility.

The 1843619 holds active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment. Selection of the 1843619 is appropriate for applications requiring direct functional replacement of the obsolete 1911020.

Frequently Asked Questions (FAQ)

Q: Can the 1843619 be used as a direct replacement for the 1911020 in existing designs?

A: Electrical and mechanical compatibility is confirmed. However, the termination method differs (solder vs. press-fit), requiring PCB layout and assembly process modifications. Mechanical fit and connector interface remain identical.

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

A: The primary differences are product status (obsolete vs. active), series designation (COMBICON EMCV vs. COMBICON MCV), termination technology (press-fit vs. solder), and contact tail length (0.150" vs. 0.134"). All electrical ratings and mechanical dimensions are equivalent.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical compliance profiles: ROHS3 compliant, UL94 V-0 flammability rating, REACH unaffected, and EAR99 ECCN classification. No compliance disadvantage exists with the substitute.

Q: What is the impact of switching from press-fit to solder termination?

A: Press-fit termination requires precision-drilled holes and mechanical insertion; solder termination requires standard PCB pads and reflow or wave soldering processes. The choice depends on manufacturing capability and design requirements. Both methods provide equivalent electrical performance.

Q: Is the 1843619 available in the same packaging as the 1911020?

A: The 1911020 packaging is listed as unspecified, while the 1843619 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
