Engineering Selection Recommendations

The Phoenix Contact 1910762 is a direct functional substitute for the obsolete 1981539 terminal block plug. Selection is based on the following engineering criteria:

Electrical Performance: Both components meet identical UL current (10A) and voltage (300V) ratings. The 1910762 provides 320V IEC rating compared to the 1981539's 630V IEC rating, which remains adequate for standard industrial applications within the 300V UL specification envelope.

Mechanical Compatibility: Identical 11-position configuration, 5.00mm pitch spacing, 180° wire entry orientation, and free-hanging in-line mounting ensure direct mechanical interchangeability without redesign or mechanical adaptation.

Termination Method: Both components employ screwless push-in spring termination compatible with 12-26 AWG (0.2-2.5mm²) wire gauges. The 1910762 eliminates the leg spring option present in the 1981539, but maintains full push-in spring functionality for standard applications.

Regulatory Compliance: Both components maintain UL94 V-0 flammability rating and RoHS compliance status, satisfying regulatory requirements for equivalent applications.

Product Availability: The 1910762 holds active product status with 838 units in stock, providing supply continuity for the obsolete 1981539 (1057 units remaining inventory).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1910762 directly replace the 1981539 in existing installations?

A: Yes. Both components share identical electrical ratings (10A UL, 300V UL), mechanical configuration (11 positions, 5.00mm pitch, 180° entry), and termination method (push-in spring). No circuit modifications or mechanical adaptations are required.

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

A: The 1981539 is rated 630V IEC, while the 1910762 is rated 320V IEC. Both meet the 300V UL specification. The 1910762 is suitable for applications operating within 300V UL or 320V IEC limits.

Q: Are the wire gauge specifications identical?

A: Yes. Both components accept 12-26 AWG (0.2-2.5mm²) wire gauges with identical termination characteristics.

Q: Does the 1910762 support the same mounting configuration?

A: Yes. Both components are configured for free-hanging in-line mounting with 180° wire entry orientation.

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

A: The 1981539 offers both leg spring and push-in spring termination options. The 1910762 provides push-in spring termination only. For standard applications using push-in spring connection, both components are functionally equivalent.

Q: Are both components RoHS compliant?

A: Yes. Both the 1981539 and 1910762 are RoHS compliant and maintain UL94 V-0 flammability rating.

Q: Which part should be selected for new designs?

A: The Phoenix Contact 1910762 is recommended for new designs due to active product status and confirmed supply availability. The 1981539 is obsolete and should be replaced in existing designs where feasible.
