Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1981610 is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: 4-position plug with male pins, 0.197" (5.00mm) pitch
• Mounting & Orientation: Free-hanging in-line configuration with 180° wire entry
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
• Termination Method: Screwless push-in spring technology for tool-free wire insertion
• Material & Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance
• Wire Compatibility: Support for 12-26 AWG (0.2-2.5mm²) wire gauges

The Phoenix Contact 1910843 qualifies as a direct substitute based on matching all critical parameters within acceptable electrical and mechanical tolerances.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910843 is the appropriate substitute for the obsolete 1981610 based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical IEC current ratings (12A) and UL ratings (10A at 300V). The 1910843 operates at 320V IEC, which is lower than the original 630V rating. This substitution is valid for applications operating at or below 320V IEC. Applications requiring the full 630V IEC rating cannot use this substitute.

Mechanical & Functional Equivalence: The 4-position configuration, 5.00mm pitch, 180° wire entry, and free-hanging in-line mounting are identical. Both components support 12-26 AWG wire gauges and feature identical insulation height and wire strip length specifications.

Material & Compliance: Both components use polyamide housing with UL94 V-0 flammability rating, ensuring equivalent safety performance in applications requiring flame resistance.

Product Status Advantage: The 1910843 is currently active in production, ensuring long-term availability and supply chain reliability compared to the obsolete 1981610.

Termination Compatibility: Both employ screwless push-in spring termination, maintaining identical installation methodology and tool requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1910843 directly replace the 1981610 in all applications?

A: Direct replacement is valid for applications operating at 320V IEC or lower. Applications requiring the full 630V IEC rating of the original component cannot use the 1910843 as a substitute. Verify your system voltage before substitution.

Q: Are the physical dimensions and mounting interfaces identical?

A: Yes. Both components share identical pitch (5.00mm), insulation height (15.00mm), wire strip length (10mm), and free-hanging in-line mounting configuration. No mechanical redesign is required for substitution.

Q: What is the difference in termination style between these two parts?

A: The 1981610 features both leg spring and push-in spring termination options, while the 1910843 provides push-in spring termination only. Both support tool-free wire insertion. Verify that push-in spring termination meets your application requirements.

Q: Is the 1910843 RoHS compliant?

A: RoHS compliance status for the 1910843 is not specified in the provided technical data. Contact Phoenix Contact directly to confirm RoHS compliance if this certification is required for your application.

Q: Why is the 1981610 obsolete?

A: The 1981610 is classified as obsolete by Phoenix Contact. The 1910843 represents the current production equivalent within the COMBICON FKIC series, ensuring ongoing availability and support.

Q: Can I use the 1910843 in high-voltage applications rated for 630V?

A: No. The 1910843 is rated for 320V IEC maximum. Using this component in 630V applications exceeds its voltage rating and creates a safety hazard. Identify an alternative component rated for 630V if your application requires this voltage level.

Q: Are the wire gauge specifications the same?

A: Yes. Both components accept 12-26 AWG (0.2-2.5mm²) wire gauges with identical wire strip length (10mm), ensuring compatible installation procedures.
