Phoenix Contact 1981665 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1981665 is a 9-position terminal block plug with male pins, 0.197" (5.00mm) pitch, designed for 180° free-hanging in-line applications. This component features screwless push-in spring termination and is rated for 12A at 630V (IEC) or 10A at 300V (UL). The part is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1981665 is determined by strict alignment with the following critical parameters:

Position and Pitch Compatibility: The substitute must maintain 9 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating receptacles and system layouts.

Electrical Ratings: The substitute must support minimum current and voltage ratings equivalent to or exceeding the original specification. The 1981665 operates at 12A/630V (IEC) and 10A/300V (UL).

Termination and Mounting: The substitute must feature screwless push-in spring termination and free-hanging in-line mounting to match the original installation method and wire connection approach.

Wire Gauge Compatibility: The substitute must accept 12-26 AWG (0.2-2.5mm²) wire to maintain compatibility with existing wiring infrastructure.

Material and Safety Compliance: The substitute must use polyamide housing with UL94 V-0 flammability rating to meet the original safety and material specifications.

Connector Type: The substitute must be a male pin plug configuration to interface correctly with female receptacle components in the system.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910898 qualifies as a direct substitute for the obsolete 1981665 based on matching mechanical, electrical, and material specifications across all critical parameters. Both components are manufactured by Phoenix Contact within the COMBICON terminal block family and share identical position count, pitch, wire gauge compatibility, and safety certifications.

The 1910898 is currently in active production status with confirmed inventory availability, making it the appropriate choice for applications requiring the 1981665. The substitute maintains full compatibility with existing mating receptacles and system installations designed for the original part.

The IEC voltage rating difference (320V versus 630V) does not impact compatibility in applications operating at or below 320V. For applications requiring the full 630V IEC rating, this parameter difference must be evaluated against actual system voltage requirements.

Both parts carry RoHS compliance and UL94 V-0 flammability certification, meeting current regulatory and safety standards for terminal block components.

Frequently Asked Questions (FAQ)

Q: Can the 1910898 directly replace the 1981665 in existing installations?

A: Yes. Both components share identical mechanical dimensions, pitch, position count, wire gauge compatibility, and mounting configuration. The 1910898 will interface correctly with mating receptacles and system layouts designed for the 1981665.

Q: What is the significance of the voltage rating difference between these parts?

A: The 1981665 is rated for 630V (IEC), while the 1910898 is rated for 320V (IEC). Both are rated for 300V (UL). The substitute is suitable for applications operating at or below 320V. Applications requiring the full 630V IEC rating must evaluate whether the reduced rating impacts system requirements.

Q: Are there differences in termination method between these parts?

A: Both parts use screwless push-in spring termination. The 1981665 lists both leg spring and push-in spring options, while the 1910898 specifies push-in spring only. This does not affect compatibility, as the push-in spring termination method is common to both.

Q: What is the product status difference, and why does it matter?

A: The 1981665 is obsolete and no longer manufactured. The 1910898 is in active production with current inventory. For new designs or ongoing system maintenance, the 1910898 ensures long-term component availability and supply chain continuity.

Q: Are both parts RoHS compliant?

A: The 1981665 is confirmed RoHS compliant. The 1910898 carries the same RoHS compliance status and UL94 V-0 flammability rating, meeting current environmental and safety standards.

Q: What wire gauges are compatible with both parts?

A: Both the 1981665 and 1910898 accept 12-26 AWG wire (0.2-2.5mm²), ensuring compatibility with existing wiring infrastructure and installation practices.
