Phoenix Contact 1749298 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1749298 is an 11-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 eligibility for the Phoenix Contact 1749298 is determined by strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Phoenix Contact COMBICON ISPC)
• Identical position count and pitch (11 positions, 0.300"/7.62mm)
• Matching connector type and gender (Plug, Male Pins)
• Identical wire entry orientation (180°)
• Equivalent electrical ratings (IEC and UL current/voltage specifications)
• Compatible wire gauge range (8-24 AWG / 0.2-10mm²)
• Matching termination technology (Screwless Push-In Spring)
• Identical mounting configuration (Free Hanging In-Line)

The Phoenix Contact 1748956 meets all substitution criteria as an active product within the same series, offering direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1748956 is the direct active equivalent for the obsolete 1749298 model. Both components share identical electrical ratings, mechanical dimensions, and termination specifications within the COMBICON ISPC series. The 1748956 maintains full RoHS compliance and UL94 V-0 flammability certification, meeting the same regulatory requirements as the original part.

The primary distinction between these parts is the feature set: the 1749298 includes a mating flange, while the 1748956 incorporates a locking ramp. This difference does not affect electrical or mechanical compatibility in applications where the connector is used as a plug interface. Selection between these variants depends on the specific mechanical mounting requirements of the target application.

For new designs or system upgrades, the 1748956 is the recommended choice due to its active product status and continued availability. For legacy system maintenance requiring exact feature parity with the original 1749298, the mating flange feature should be evaluated against the application's mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1748956 directly replace the 1749298 in existing installations?

A: Yes. Both components are mechanically and electrically identical across all critical parameters: 11 positions, 0.300" pitch, 180° wire entry, identical current and voltage ratings, and matching wire gauge compatibility. The difference in features (mating flange vs. locking ramp) does not affect connector functionality in standard plug applications.

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

A: The 1749298 is classified as obsolete, indicating Phoenix Contact no longer manufactures this variant. The 1748956 is an active product with ongoing production and availability. For procurement purposes, the 1748956 should be specified for new orders and system designs.

Q: Are there differences in packaging between these parts?

A: The 1749298 is listed with unspecified packaging, while the 1748956 is supplied in bulk packaging. Packaging differences do not affect component performance or compatibility; they relate only to order quantities and handling.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1749298 and 1748956 are RoHS compliant and carry the UL94 V-0 flammability rating. They meet identical IEC and UL electrical specifications for current and voltage.

Q: What wire gauges are compatible with these terminal block plugs?

A: Both components accept wire gauges from 8-24 AWG, equivalent to 0.2-10mm². This range accommodates standard industrial wiring applications within the specified current and voltage limits.

Q: How do the mating flange and locking ramp features differ functionally?

A: The mating flange on the 1749298 provides a mechanical interface for connector alignment, while the locking ramp on the 1748956 provides positive engagement and retention. Both features serve mechanical coupling purposes; selection depends on the mating connector design and application requirements.
