Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1981597 is based on strict equivalence across the following critical parameters:

Connector Type & Configuration: 2-position plug with male pins, matching the COMBICON series family
Electrical Ratings: Current and voltage ratings must meet or exceed the original specification (12A/630V IEC minimum)
Mechanical Compatibility: 0.197" (5.00mm) pitch, 180° wire entry, free-hanging in-line mounting
Termination Method: Screwless push-in spring technology for tool-free installation
Wire Compatibility: Support for 12-26 AWG (0.2-2.5mm²) wire gauge range
Material & Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance

The Phoenix Contact 1910827 qualifies as a direct substitute based on these parameters. Both components share identical mechanical dimensions, pitch, wire entry orientation, and wire gauge compatibility. The 1910827 maintains the required electrical performance and material specifications.

Engineering Selection Recommendations

The Phoenix Contact 1910827 is the qualified substitute for the obsolete 1981597 based on the following engineering criteria:

Electrical Compatibility: Both components are rated for 12A at IEC voltage levels and 10A at 300V UL. The 1910827 carries a lower IEC voltage rating of 320V compared to the original 630V specification. This difference must be evaluated against the actual system voltage requirements. For applications operating at or below 320V IEC, the 1910827 provides full electrical equivalence.

Mechanical & Functional Equivalence: The 1910827 maintains identical pitch (5.00mm), wire entry angle (180°), mounting configuration (free-hanging in-line), and wire gauge compatibility (12-26 AWG). Physical interchangeability is confirmed.

Material & Compliance: Both components utilize polyamide housing with UL94 V-0 flammability rating. The 1910827 maintains RoHS compliance. These specifications ensure equivalent safety and environmental performance.

Product Status Advantage: The 1910827 is classified as active, ensuring continued availability and supply chain reliability compared to the obsolete 1981597.

Frequently Asked Questions (FAQ)

Q: Can the 1910827 directly replace the 1981597 in all applications?

A: Direct replacement is possible for applications where the system voltage does not exceed 320V IEC. The 1910827 maintains identical mechanical dimensions, pitch, wire entry orientation, and current ratings. If your application requires the full 630V IEC rating of the original part, voltage compatibility must be verified before substitution.

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

A: The primary difference is the IEC voltage rating. The 1981597 is rated for 630V IEC, while the 1910827 is rated for 320V IEC. Both maintain identical 12A current capacity and 300V UL rating. The 1910827 also represents the active product line, whereas the 1981597 is obsolete.

Q: Are the termination methods compatible?

A: Both components use screwless push-in spring termination, ensuring tool-free installation. The 1981597 lists both leg spring and push-in spring options, while the 1910827 specifies push-in spring. This represents a compatible simplification in the active product design.

Q: What wire gauges are supported?

A: Both the 1981597 and 1910827 support 12-26 AWG wire gauge range, equivalent to 0.2-2.5mm². Wire compatibility is identical between the two components.

Q: Is the 1910827 RoHS compliant?

A: Yes, the 1910827 is RoHS compliant and maintains the UL94 V-0 flammability rating of the original 1981597, ensuring equivalent environmental and safety compliance.

Q: What is the packaging difference?

A: The 1981597 was supplied with unspecified packaging, while the 1910827 is available in bulk packaging. This difference does not affect component functionality or compatibility.
