Phoenix Contact 1981571 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1981571 is a 15-position terminal block plug with male pins, 5.00mm pitch, designed for 180° free-hanging in-line applications. This component features screwless push-in spring termination and supports wire gauges from 12-26 AWG (0.2-2.5mm²). The part is classified as obsolete, making identification of compatible substitutes essential for ongoing system maintenance and new designs requiring equivalent functionality.

Substitute Part Grouping Explanation

Substitution eligibility for the 1981571 is determined by the following critical parameters:

Position Count: Must be 15 positions
Pitch Tolerance: 5.00mm (0.197") to 5.08mm (0.200") - minor pitch variation within mechanical compatibility
Plug Configuration: Male pins, 180° free-hanging in-line orientation
Electrical Ratings: Minimum 12A (IEC) and 630V (IEC) capability
Wire Gauge Compatibility: Support for 12-26 AWG (0.2-2.5mm²)
Termination Method: Screwless push-in spring technology
Housing Material: Polyamide (PA) or Nylon construction
Compliance: RoHS compliant status

The Phoenix Contact 1910801 qualifies as a substitute based on these parameters. While the pitch differs slightly (5.08mm vs 5.00mm), both components share identical position count, electrical ratings, wire gauge support, and mounting configuration. The 1910801 represents an active product within the COMBICON FKIC series, providing functional equivalence for applications previously using the obsolete 1981571.

Engineering Selection Recommendations

The Phoenix Contact 1910801 is the designated substitute for the obsolete 1981571. Both components maintain identical electrical performance specifications (12A IEC, 630V IEC) and support the same wire gauge range (12-26 AWG). Both achieve UL94 V-0 flammability rating and RoHS compliance, ensuring regulatory alignment for industrial applications.

The primary distinction is product status: the 1981571 is obsolete, while the 1910801 remains in active production. The 1910801 incorporates a locking ramp feature and operates within the COMBICON FKIC series, representing the current generation equivalent. The pitch variance of 0.08mm (5.00mm to 5.08mm) falls within standard mechanical tolerance for connector mating surfaces in this product category.

For new designs or system replacements, the 1910801 provides direct functional substitution with the advantage of ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can the 1910801 directly replace the 1981571 in existing installations?

A: Yes. Both components share identical electrical ratings (12A IEC, 630V IEC), wire gauge compatibility (12-26 AWG), and mounting configuration (15-position, 180° free-hanging). The pitch difference of 0.08mm is within standard mechanical tolerance for mating connector interfaces.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The pitch difference represents a 0.16% variance. Both measurements fall within the standard tolerance band for 5mm-class terminal block connectors. Mechanical mating compatibility is maintained across both pitch specifications in this product category.

Q: Why is the 1981571 classified as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. The 1910801 represents the active equivalent within Phoenix Contact's current COMBICON terminal block portfolio, offering the same functional performance with ongoing production support.

Q: Are there any differences in termination capability between these parts?

A: Both components utilize screwless push-in spring termination and support identical wire gauge ranges (12-26 AWG, 0.2-2.5mm²). The 1910801 includes a locking ramp feature for enhanced mechanical retention.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1981571 and 1910801 are RoHS compliant, achieve UL94 V-0 flammability rating, and carry MSL 1 (Unlimited) moisture sensitivity classification. Electrical performance meets both IEC and UL standards.

Q: What packaging is available for the 1910801?

A: The 1910801 is supplied in bulk packaging, with 802 pieces currently in stock as new original inventory.
