Phoenix Contact 1727883 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1727883 is a 10-position terminal block header from the COMBICON DFK-PC series, designed for PCB-mounted applications with male pins and right-angle rear panel connections. This component features a green housing, snap-lock panel mount design, and is rated for 300V UL voltage and 41A UL current.

The 1727883 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this connector.

Substitute Part Grouping Explanation

The Phoenix Contact 1727663 qualifies as a direct substitute for the 1727883 based on the following critical parameters:

Electrical Compatibility: Both parts maintain identical voltage (300V UL) and current (41A UL) ratings
Mechanical Compatibility: Both feature 10 positions per level, 0.300" (7.62mm) pitch, identical width (4.004" / 101.70mm), and compatible panel thickness range (0.039 ~ 0.118" / 1.0 ~ 3.0mm)
Connection Type: Both provide header male pins on the front panel and PCB pins with right-angle rear panel connection
Housing Color: Both are green
Compliance: Both are RoHS compliant with MSL rating of 1 (Unlimited)
Series Alignment: Both belong to the COMBICON DFK-PC series

The primary distinction is product status: the 1727883 is obsolete, while the 1727663 is active. The 1727663 includes a front flange on the snap-lock panel mount mechanism, which provides enhanced mechanical retention without affecting electrical or dimensional compatibility.

Engineering Selection Recommendations

The Phoenix Contact 1727663 is the appropriate substitute for the obsolete 1727883. Both parts maintain full electrical and mechanical compatibility across all critical parameters: voltage rating, current rating, position count, pitch, connection types, and physical dimensions.

The 1727663 offers the additional advantage of active product status, ensuring ongoing availability, manufacturer support, and compliance with current regulatory requirements. The front flange enhancement on the snap-lock mechanism provides improved mechanical retention without introducing any incompatibility with existing PCB layouts or panel mounting configurations.

For new designs or production continuity, the 1727663 should be specified. For legacy systems currently using the 1727883, direct substitution with the 1727663 is electrically and mechanically sound.

Frequently Asked Questions (FAQ)

Q: Can the 1727663 be used as a direct replacement for the 1727883 in existing designs?

A: Yes. The 1727663 maintains identical electrical ratings (300V UL, 41A UL), mechanical dimensions (4.004" width, 0.300" pitch, 10 positions), connection types (male pin header, right-angle PCB pins), and panel mounting compatibility (0.039 ~ 0.118" panel thickness range). The front flange on the 1727663 snap-lock mechanism provides enhanced retention and does not affect compatibility.

Q: What is the significance of the front flange on the 1727663?

A: The front flange is a mechanical enhancement that improves panel mount retention. It does not alter electrical performance, dimensional compatibility, or PCB layout requirements. Existing designs using the 1727883 will accommodate the 1727663 without modification.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant with identical MSL ratings (1 - Unlimited). Both carry the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications. No compliance gaps exist between the two parts.

Q: Why is the 1727883 listed as obsolete?

A: The 1727883 has been superseded by the 1727663 within the Phoenix Contact product line. The 1727663 represents the current active offering in the COMBICON DFK-PC series for this connector configuration.

Q: What packaging is available for the 1727663?

A: The 1727663 is supplied in bulk packaging, with 987 pieces currently in stock as new original inventory.
