Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1749308 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: 12-position plug with male pins in COMBICON ISPC series
• Pitch & Spacing: 0.300" (7.62mm) center-to-center spacing
• Electrical Ratings: IEC 41A/1kV and UL 35A/600V performance levels
• Termination Method: Screwless push-in spring technology
• Wire Compatibility: Support for 8-24 AWG (0.2-10mm²) conductors
• Mechanical Form Factor: Free-hanging in-line orientation with 180° wire entry
• Material & Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance

The Phoenix Contact 1748969 meets all these criteria and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1748969 is the direct substitute for the obsolete 1749308. Both components are manufactured by Phoenix Contact within the COMBICON ISPC series and share identical electrical, mechanical, and material specifications. The 1748969 maintains active product status, ensuring continued availability and supply chain reliability.

Key differentiators between the two parts are limited to packaging format (1749308 supplied as individual units; 1748969 supplied in bulk) and connector features (1749308 includes mating flange; 1748969 includes locking ramp). These differences do not affect electrical or mechanical compatibility in applications where the 1749308 was originally specified.

Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting modern regulatory requirements. The MSL rating of 1 (unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 1748969 directly replace the 1749308 in existing applications?

A: Yes. Both components share identical electrical ratings (41A IEC / 35A UL), voltage specifications (1kV IEC / 600V UL), wire gauge compatibility (8-24 AWG), pitch (7.62mm), and termination method (screwless push-in spring). Mechanical form factor and mounting orientation are also equivalent.

Q: What is the difference between the mating flange on 1749308 and the locking ramp on 1748969?

A: The mating flange and locking ramp are distinct connector features that serve different mechanical functions. Selection between these variants depends on the mating receptacle design in your application. Verify that your mating connector is compatible with the locking ramp feature of the 1748969 before substitution.

Q: Are there packaging differences between these parts?

A: Yes. The 1749308 is supplied as individual units, while the 1748969 is supplied in bulk packaging. This affects procurement and inventory management but does not impact component performance or electrical characteristics.

Q: Do both parts meet current regulatory standards?

A: Yes. Both the 1749308 and 1748969 are RoHS compliant and carry UL94 V-0 flammability certification. The 1748969, as an active product, continues to meet current manufacturing and compliance standards.

Q: What wire gauges are supported by the 1748969?

A: The 1748969 supports wire gauges from 8-24 AWG, equivalent to 0.2-10mm² conductor cross-section. This range is identical to the 1749308 specification.
