Engineering Selection Recommendations

The Phoenix Contact 1748888 is the direct functional equivalent for applications currently using the obsolete 1749227. Both components maintain identical electrical performance (41A IEC / 35A UL ratings) and mechanical compatibility within the COMBICON ISPC series.

Selection of 1748888 is supported by:

Active Product Status: 1748888 is actively manufactured and supported, ensuring long-term availability and supply chain continuity
Enhanced Compliance: ROHS3 certification provides updated regulatory alignment compared to the RoHS Compliant designation of 1749227
Functional Equivalence: All critical parameters—pitch, wire entry angle, termination method, current/voltage ratings, and wire gauge compatibility—are identical
Feature Enhancement: The locking ramp feature in 1748888 provides additional mechanical security compared to the mating flange of 1749227, without affecting electrical or dimensional compatibility

For applications requiring the exact feature set of 1749227, the mating flange configuration remains available through direct inquiry, but 1748888 serves as the recommended active production equivalent.

Frequently Asked Questions (FAQ)

Q: Can 1748888 be used as a direct replacement for 1749227 in existing designs?

A: Yes. Both components share identical electrical ratings (41A IEC / 35A UL), voltage specifications (1kV IEC / 600V UL), pitch (0.300" / 7.62mm), wire gauge compatibility (8-24 AWG / 0.2-10mm²), and termination method (screwless push-in spring). Physical mounting and connector orientation are equivalent.

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

A: The mating flange (1749227) and locking ramp (1748888) are distinct mechanical features that do not affect electrical performance or dimensional compatibility. Selection between them depends on application-specific mechanical retention requirements. Both maintain the same pitch, wire entry angle, and connector footprint.

Q: Is 1748888 suitable for new designs?

A: Yes. 1748888 is an active product with current manufacturing support, ROHS3 compliance, and full availability. It is the recommended choice for new designs requiring 4-position, 7.62mm pitch terminal block plugs with push-in spring termination.

Q: Are there packaging differences between these parts?

A: 1749227 was supplied with unspecified packaging, while 1748888 is available in bulk packaging. Packaging format does not affect component functionality or electrical performance.

Q: What compliance certifications apply to both parts?

A: Both components meet UL94 V-0 flammability requirements and are RoHS compliant. 1748888 carries the updated ROHS3 certification. Both are rated for IEC and UL standards with identical electrical specifications.
