Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1749230 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: 5-position plug with male pins in COMBICON ISPC series
• Pitch & Spacing: 0.300" (7.62mm) pitch for mechanical and electrical compatibility
• Wire Entry Orientation: 180° free-hanging in-line configuration
• Termination Method: Screwless push-in spring technology
• Electrical Ratings: IEC 41A/1kV and UL 35A/600V performance levels
• Wire Compatibility: 8-24 AWG (0.2-10mm²) acceptance range
• Material & Compliance: Polyamide housing, UL94 V-0 flammability rating, RoHS compliance, tin contact finish

The substitute part 1748891 maintains identical specifications across all critical parameters while offering active product status and improved feature set (locking ramp mechanism).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1748891 is a direct functional equivalent to the obsolete 1749230. Both components are manufactured by Phoenix Contact within the COMBICON ISPC series and maintain identical electrical ratings, mechanical dimensions, and material specifications. The 1748891 carries active product status, ensuring long-term availability and supply chain continuity.

Both parts satisfy RoHS compliance requirements and UL94 V-0 flammability certification. The tin contact finish and polyamide housing provide equivalent environmental performance and durability characteristics. Wire gauge acceptance ranges and termination methods are identical, ensuring seamless integration into existing circuit designs.

The primary distinction is the feature set: the 1749230 includes a mating flange, while the 1748891 incorporates a locking ramp mechanism. This difference does not affect electrical or mechanical compatibility but may influence mechanical retention requirements in specific applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1748891 directly replace 1749230 in existing designs?

A: Yes. Both components share identical electrical ratings (IEC 41A/1kV, UL 35A/600V), mechanical pitch (7.62mm), wire gauge compatibility (8-24 AWG), and termination technology (screwless push-in spring). The 1748891 is functionally equivalent and maintains the same form factor for free-hanging in-line mounting.

Q: What is the difference between the mating flange and locking ramp features?

A: The 1749230 includes a mating flange for mechanical alignment during connector mating. The 1748891 incorporates a locking ramp mechanism for enhanced retention. Both features serve mechanical positioning functions and do not affect electrical performance or wire acceptance specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1749230 and 1748891 are RoHS compliant with UL94 V-0 flammability ratings and identical material compositions (polyamide housing, tin contact finish).

Q: Why is 1749230 listed as obsolete?

A: The 1749230 has been superseded by the 1748891 within the Phoenix Contact product line. The 1748891 maintains all functional specifications while offering active product status and improved feature integration.

Q: What wire gauges are supported by both parts?

A: Both components accept wire gauges from 8-24 AWG (0.2-10mm²) with a 15mm wire strip length requirement.

Q: Are packaging differences significant for component selection?

A: The 1749230 is listed with unspecified packaging, while the 1748891 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not influence electrical or mechanical compatibility.
