Phoenix Contact 1792274 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1792274 is a 7-position wire-to-board terminal block from the COMBICON PLA series, designed for through-hole PCB mounting with a 30° angle orientation and 7.5mm pitch. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations.

The primary reason for identifying alternatives is the discontinued status of the COMBICON PLA series. Active substitute parts maintain electrical and mechanical compatibility while offering current manufacturing support and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1792274 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (41 A), voltage rating (1 kV minimum), and wire gauge acceptance range
• Mechanical Compatibility: 7-position configuration, 7.5mm pitch, 30° board angle, through-hole mounting
• Termination Method: Screwless spring-based wire termination with lever actuation
• Physical Form Factor: Green polyamide housing, single-level design

The substitute part Phoenix Contact 1098180 satisfies all mandatory compatibility criteria while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1098180 is the direct substitute for the obsolete 1792274 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical current (41 A) and voltage (1 kV) ratings, ensuring no derating or circuit redesign is required.

Mechanical Compatibility: Identical pitch (7.5mm), position count (7), board angle (30°), and through-hole mounting ensure direct PCB footprint compatibility without layout modifications.

Product Status and Compliance: The 1098180 is an active product with ROHS3 compliance, providing long-term availability and regulatory alignment. The 1792274's obsolete status necessitates transition to an active alternative.

Wire Gauge Consideration: The 1098180 accepts 8-22 AWG wire, which encompasses the 1792274's 10-24 AWG range. This broader acceptance range provides design flexibility without compromising compatibility for existing applications using 10-24 AWG conductors.

Termination Method: Both parts employ screwless spring-based termination with lever actuation, maintaining identical installation procedures and tooling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1098180 be used as a direct replacement for the 1792274 without PCB modifications?

A: Yes. Both parts share identical pitch (7.5mm), position count (7), board angle (30°), and through-hole mounting specifications. No PCB layout changes are required.

Q: What is the difference in wire gauge acceptance between these parts?

A: The 1792274 accepts 10-24 AWG wire, while the 1098180 accepts 8-22 AWG. The 1098180's range encompasses the original part's specification, ensuring compatibility with existing wire sizes. Applications using 8-9 AWG or 23-24 AWG conductors will have different compatibility profiles.

Q: Are the termination methods compatible?

A: Both parts use screwless spring-based wire termination with lever actuation. Installation procedures and operator training remain unchanged. The 1098180 uses leg spring and push-in spring technology versus the 1792274's spring cage and tension clamp, but both achieve equivalent electrical and mechanical connection reliability.

Q: What is the compliance difference between RoHS and ROHS3?

A: ROHS3 represents the current regulatory standard with expanded restricted substance requirements. The 1098180's ROHS3 compliance ensures alignment with current and future regulatory requirements, while the 1792274's RoHS compliance reflects an earlier standard iteration.

Q: Is the 1098180 suitable for applications requiring the full -40°C to 105°C operating temperature range?

A: The 1098180 is rated for -40°C to 105°C operation. The 1792274's operating temperature specification was not provided in the original documentation. Applications requiring confirmed low-temperature or high-temperature performance should reference the 1098180's published thermal specifications.

Q: Are there any inventory or lead-time considerations?

A: The 1792274 is obsolete with limited remaining stock. The 1098180 is an active product with current manufacturing support, ensuring reliable availability for new procurements and ongoing system maintenance.
