Phoenix Contact 1981649 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1981649 is a 7-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 active equivalent components essential for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1981649 is determined by strict alignment across the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain 7 positions with 0.197" (5.00mm) pitch spacing to ensure mechanical and electrical compatibility with mating receptacles.

Electrical Ratings: The substitute must support minimum current and voltage specifications. The 1981649 operates at 12A (IEC) and 630V (IEC). Substitute parts meeting or exceeding these ratings are electrically compatible.

Termination and Wire Compatibility: Both the main part and substitute must support the same wire gauge range (12-26 AWG / 0.2-2.5mm²) and employ compatible termination methods (screwless push-in spring technology).

Physical Form Factor: Free-hanging in-line mounting with 180° wire entry orientation and mating flange features must be preserved.

Material and Compliance: Housing material (Polyamide/Nylon) and flammability rating (UL94 V-0) ensure consistent performance and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910872 serves as a direct functional equivalent to the obsolete 1981649 across all critical mechanical and electrical parameters. Both components share identical position count, pitch spacing, wire entry orientation, and termination wire gauge compatibility.

The 1910872 is classified as an active product, ensuring ongoing availability and supply chain continuity. This status is significant for applications requiring long-term component sourcing and maintenance support.

Both parts maintain UL94 V-0 flammability compliance and identical UL electrical ratings (10A at 300V), confirming regulatory equivalence for UL-governed applications. The 1981649 carries a higher IEC voltage rating (630V versus 320V), which should be evaluated against specific application voltage requirements. For systems operating below 320V IEC, the 1910872 provides full electrical compatibility.

The termination method difference (1981649 includes both leg spring and push-in spring; 1910872 includes push-in spring only) does not affect functional compatibility, as both employ screwless push-in spring technology for wire termination.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1910872 directly replace the 1981649 in existing installations?

A: Yes, for applications operating at or below 320V IEC. Both components share identical mechanical form factors, pitch spacing, position count, and wire gauge compatibility. The 1910872 is mechanically and electrically interchangeable with the 1981649 within the specified voltage parameters.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 1981649 is obsolete and no longer manufactured by Phoenix Contact. The 1910872 is an active product with ongoing production and availability. For new designs or long-term maintenance requirements, the 1910872 is the recommended selection to ensure supply chain continuity.

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

A: The 1981649 supports both leg spring and push-in spring termination, while the 1910872 supports push-in spring termination only. Both employ screwless technology. For applications using push-in spring termination, the parts are functionally equivalent.

Q: How do the IEC voltage ratings differ, and does this affect compatibility?

A: The 1981649 is rated at 630V IEC, while the 1910872 is rated at 320V IEC. Both are rated at 300V UL. For applications operating at or below 320V IEC, the 1910872 provides full compatibility. Applications requiring operation above 320V IEC should retain the 1981649 or identify alternative solutions.

Q: Are both parts RoHS compliant?

A: The 1981649 is explicitly marked as RoHS Compliant. The 1910872 does not have RoHS status specified in the provided data. Verify RoHS compliance requirements with the manufacturer for the 1910872 if regulatory compliance is a design requirement.

Q: What wire gauges are supported by both components?

A: Both the 1981649 and 1910872 support wire gauges from 12-26 AWG (0.2-2.5mm²), ensuring identical wire termination compatibility.
