Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1811161 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Number of positions: 4
• Pitch: 0.098" (2.50mm)
• Plug wire entry orientation: 180°
• Mounting type: Free Hanging (In-Line)
• Type: Plug with female sockets
• Connector category: Terminal block

Electrical Compatibility Criteria: Substitute parts must meet or exceed the electrical specifications of the original component. The 1811161 operates at 2A (IEC) and 2A (UL) with voltage ratings of 160V (IEC) and 50V (UL). Substitute parts with higher current and voltage ratings remain compatible for this application.

Wire Gauge Compatibility: The original part accommodates 26 AWG (0.14mm²) wire. Substitute parts with expanded wire gauge ranges that include or exceed this specification are acceptable.

The Phoenix Contact 1881341 meets all mandatory matching criteria and provides enhanced electrical performance with higher current (4A) and voltage (320V IEC / 125V UL) ratings, along with expanded wire gauge compatibility (20-28 AWG / 0.14-0.5mm²).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1881341 is the qualified substitute for the obsolete 1811161 terminal block plug. Selection of the 1881341 is supported by the following engineering factors:

Product Status: The 1811161 is classified as obsolete, while the 1881341 maintains active product status, ensuring continued availability and manufacturing support.

Compliance and Certifications: Both parts are RoHS compliant. The 1881341 carries ROHS3 Compliant status and REACH Unaffected designation, meeting current regulatory requirements for electronic component procurement.

Electrical Performance: The 1881341 provides superior electrical ratings (4A / 320V IEC; 4A / 125V UL) compared to the original part (2A / 160V IEC; 2A / 50V UL), ensuring compatibility with the original application while providing margin for system variations.

Mechanical Compatibility: Both parts share identical mechanical specifications: 4-position configuration, 2.50mm pitch, 180° wire entry, and free hanging in-line mounting. Physical interchangeability is confirmed.

Termination Transition: The 1881341 employs screwless push-in spring termination in place of the original IDC termination. This represents a functional upgrade that simplifies field installation and maintenance procedures.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1881341 directly replace the 1811161 in existing applications?

A: Yes. Both parts share identical mechanical specifications (4 positions, 2.50mm pitch, 180° wire entry, free hanging mounting) and connector type (plug with female sockets). The 1881341 provides equal or superior electrical performance, ensuring functional compatibility.

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

A: The main differences are product status (1811161 is obsolete; 1881341 is active), termination method (IDC versus screwless push-in spring), and electrical ratings (1881341 provides higher current and voltage capacity). The 1881341 also supports a broader wire gauge range (20-28 AWG versus 26 AWG).

Q: Are there any compatibility concerns with the different termination styles?

A: No. The termination style difference (IDC to push-in spring) affects only the wire connection method, not the connector interface. The mating interface remains identical, ensuring plug-and-socket compatibility.

Q: Does the expanded wire gauge range of the 1881341 affect compatibility?

A: No. The 1881341 accommodates 20-28 AWG (0.14-0.5mm²), which includes the original 26 AWG (0.14mm²) specification. Existing wire gauges used with the 1811161 remain fully compatible.

Q: What is the significance of the ROHS3 Compliant status on the 1881341?

A: ROHS3 Compliant status indicates the 1881341 meets current European Union Restriction of Hazardous Substances regulations. This certification is required for procurement in regulated markets and represents compliance with the most recent regulatory standards.

Q: Is the 1881341 suitable for new design implementations?

A: Yes. The active product status, current regulatory compliance (ROHS3, REACH Unaffected), and enhanced electrical specifications make the 1881341 the appropriate choice for new designs requiring 4-position, 2.50mm pitch terminal block plugs with 180° wire entry and free hanging mounting.
