Phoenix Contact 1749272 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1749272 is a 9-position terminal block plug with male pins, 0.300" (7.62mm) pitch, designed for 180° free-hanging in-line applications. This component features screwless push-in spring termination and supports wire gauges from 8-24 AWG (0.2-10mm²). The part is classified as obsolete, making identification of active equivalent models essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1749272 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current and voltage ratings (IEC and UL standards) must match or exceed the original part
• Physical Configuration: Number of positions (9), pitch (7.62mm), and wire entry angle (180°) must be identical
• Termination Method: Screwless push-in spring termination is required for mechanical and electrical compatibility
• Mounting Orientation: Free-hanging in-line mounting type must be maintained
• Wire Compatibility: Wire gauge range (8-24 AWG / 0.2-10mm²) must accommodate the same conductor sizes
• Material and Compliance: Housing material, flammability rating (UL94 V-0), and RoHS compliance must be equivalent

The Phoenix Contact 1748930 meets all substitution criteria as an active equivalent to the obsolete 1749272.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1748930 is the direct active equivalent for the obsolete 1749272. Both components are manufactured by Phoenix Contact within the COMBICON ISPC series and maintain identical electrical, mechanical, and material specifications. The 1748930 carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts comply with RoHS regulations and carry UL94 V-0 flammability certification, meeting industrial safety and environmental standards. The electrical performance is equivalent across both IEC and UL rating systems, supporting applications requiring 41A (IEC) or 35A (UL) current capacity at 1 kV (IEC) or 600V (UL) voltage levels.

The primary distinction between the two parts is the mating feature: the 1749272 includes a mating flange, while the 1748930 includes a locking ramp. This difference does not affect electrical or mechanical compatibility with standard COMBICON ISPC receptacles, as both features serve to enhance connection security through different mechanical approaches.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1748930 directly replace the 1749272 in existing applications?

A: Yes. The 1748930 is electrically and mechanically equivalent to the 1749272 across all critical parameters: 9 positions, 7.62mm pitch, 180° wire entry, push-in spring termination, and identical current/voltage ratings. The difference in mating features (flange vs. locking ramp) does not prevent compatibility with standard COMBICON ISPC receptacles.

Q: What is the significance of the mating feature difference between these parts?

A: The 1749272 features a mating flange, while the 1748930 features a locking ramp. Both are mechanical enhancements designed to secure the connection. The choice between them depends on the receptacle design and application requirements, but both are compatible with standard COMBICON ISPC receptacle designs.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both the 1749272 and 1748930 carry identical RoHS compliance status and UL94 V-0 flammability certification. Both support the same IEC and UL electrical ratings.

Q: Why is the 1749272 listed as obsolete?

A: The 1749272 has been superseded by the 1748930 within Phoenix Contact's product portfolio. The 1748930 provides the same functionality with active manufacturing and supply support.

Q: What wire gauges are compatible with this terminal block plug?

A: Both the 1749272 and 1748930 accept wire gauges from 8-24 AWG, equivalent to 0.2-10mm² cross-sectional area.

Q: Is packaging a consideration when selecting between these parts?

A: The 1749272 was supplied with unspecified packaging, while the 1748930 is supplied in bulk packaging. For procurement purposes, the 1748930 bulk packaging is the current standard offering.
