Substitute Part Grouping Explanation

The Phoenix Contact 1098178 qualifies as a direct substitute for the 1792258 based on the following critical parameters:

• Positions and Pitch: Both components feature 5 positions per level with identical 0.295" (7.50mm) pitch, ensuring PCB footprint compatibility
• Mating Orientation: Both maintain 30° (150°) angle with board, preserving connector alignment and mechanical fit
• Current and Voltage Ratings: Both rated at 41 A and 1 kV, meeting identical electrical load requirements
• Mounting Configuration: Both are through-hole mounted terminal blocks with identical mechanical interface
• Housing Material and Color: Both use polyamide (PA) nylon construction in green, maintaining physical and environmental consistency
• Wire Termination Compatibility: Both employ screwless spring-based termination systems, though with different spring mechanisms (tension clamp vs. leg spring/push-in spring)
• Wire Gauge Range: The substitute accepts 8-22 AWG, which encompasses the original 10-24 AWG range, providing broader wire compatibility

The 1098178 represents an active product from the LPTA series with enhanced specifications including defined operating temperature range (-40°C ~ 105°C) and improved compliance certifications (ROHS3, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1098178 is the recommended substitute for the obsolete 1792258 based on the following engineering criteria:

Product Status and Lifecycle: The 1098178 is an active product with ongoing manufacturer support, ensuring long-term availability and supply chain stability. The 1792258 is obsolete, making the 1098178 the appropriate choice for new designs and production continuity.

Compliance and Certifications: The 1098178 meets ROHS3 compliance and is REACH unaffected, representing current regulatory standards. Both components maintain EAR99 export classification and identical HTSUS coding, ensuring consistent regulatory treatment.

Electrical and Mechanical Compatibility: Identical current (41 A), voltage (1 kV), pitch (7.50mm), position count (5), and mating orientation (30°) ensure direct functional equivalence. Both components support through-hole mounting with identical PCB footprints.

Wire Termination Systems: While the termination mechanisms differ (tension clamp vs. leg spring/push-in spring), both employ screwless spring-based systems. The 1098178's push-in spring design may offer improved insertion ergonomics compared to the original tension clamp design.

Wire Gauge Compatibility: The 1098178 accepts 8-22 AWG wire, which fully encompasses the original 10-24 AWG specification, providing equivalent or superior wire accommodation.

Frequently Asked Questions (FAQ)

Q: Can the 1098178 be used as a direct replacement for the 1792258 on existing PCBs?

A: Yes. Both components share identical pitch (7.50mm), position count (5), mating orientation (30°), and through-hole mounting configuration. The PCB footprint is compatible without modification.

Q: Are there differences in wire termination that affect installation?

A: Both use screwless spring-based termination. The 1792258 employs tension clamp technology, while the 1098178 uses leg spring with push-in spring design. Both are compatible with the specified wire gauge ranges, though the 1098178 accommodates a broader range (8-22 AWG vs. 10-24 AWG).

Q: What is the significance of the operating temperature specification on the 1098178?

A: The 1098178 specifies an operating temperature range of -40°C to 105°C, providing defined thermal performance parameters. The 1792258 does not include this specification. For applications requiring temperature-dependent performance verification, the 1098178's defined range offers engineering clarity.

Q: Are both components RoHS compliant?

A: Yes. The 1792258 is RoHS compliant, and the 1098178 is ROHS3 compliant, representing an upgrade to current regulatory standards. Both maintain identical MSL rating (1 - Unlimited) and ECCN classification (EAR99).

Q: What is the current availability status of each component?

A: The 1792258 is obsolete with 896 pieces in stock. The 1098178 is active with 1034 pieces in stock, ensuring ongoing availability and supply chain support.

Q: Are there any electrical performance differences between the two components?

A: No. Both components are rated for 41 A current and 1 kV voltage. Electrical performance specifications are identical.
