Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1727582 qualifies as a direct substitute for the 1727809 based on the following critical parameters:

• Identical position count (2 positions per level)
• Matching pitch specification (0.300" / 7.62mm)
• Equivalent electrical ratings (300 V UL, 41 A UL)
• Same physical width (1.604" / 40.74mm)
• Compatible panel thickness range (0.039 ~ 0.118")
• Identical connector type (Header, Male Pins front; PCB Pins right-angle rear)
• Same color specification (Green)
• Single level configuration

The primary distinction is the panel mount type: the 1727582 includes a front flange in its snap-lock mechanism, whereas the 1727809 uses standard snap-lock mounting. This difference does not affect electrical or mechanical compatibility in applications where the front flange does not create interference.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1727582 is the appropriate substitute for the obsolete 1727809 in new designs and replacement applications. The 1727582 maintains all critical electrical and mechanical specifications while offering active product status and current compliance certifications (ROHS3 vs. RoHS Compliant). The addition of a front flange to the snap-lock mechanism provides enhanced panel retention without compromising functional compatibility. Selection of the 1727582 ensures access to current inventory, ongoing manufacturer support, and compliance with contemporary regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Are the electrical ratings identical between 1727809 and 1727582? A: Yes. Both parts are rated for 300 V UL and 41 A UL, with identical pitch (0.300" / 7.62mm) and position count (2 positions per level).

Q: What is the difference in panel mount type between these parts? A: The 1727809 uses standard 2-piece snap-lock mounting. The 1727582 incorporates a front flange in its snap-lock mechanism, providing additional panel retention. This does not affect electrical compatibility.

Q: Can the 1727582 be used as a direct replacement in existing assemblies designed for the 1727809? A: Yes, provided the front flange does not create mechanical interference with the panel or surrounding components. The electrical and connector specifications are fully compatible.

Q: What compliance certifications apply to each part? A: The 1727809 carries RoHS Compliant certification. The 1727582 carries ROHS3 Compliant certification, representing current regulatory compliance. Both parts have MSL rating of 1 (Unlimited).

Q: Why is the 1727809 classified as obsolete? A: The 1727809 is no longer in active production. The 1727582 is the current active equivalent from Phoenix Contact for this terminal block configuration.

Q: Are packaging options different between these parts? A: The 1727809 packaging is listed as standard. The 1727582 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
