Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1792151 terminal block can be substituted with the LPT series model 1098172 based on the following critical parameters:

Matching Parameters:

• 7 positions per level
• 0.295" (7.50mm) pitch spacing
• Horizontal with board mating orientation
• Through hole mounting type
• Lever actuated operation
• Green polyamide housing
• Screwless spring-based wire termination

Substitution Basis: The 1098172 maintains functional and mechanical compatibility through identical position count, pitch, mounting orientation, and termination method. Both components accommodate wire gauges within overlapping ranges and feature lever-actuated operation suitable for the same PCB integration requirements. The substitute part is classified as active product status with enhanced electrical ratings and current compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1098172 (LPT series) is the designated substitute for the obsolete 1792151 (COMBICON PLH series). Selection of the 1098172 is supported by:

Product Status: The 1098172 maintains active product status, ensuring continued availability and manufacturer support, whereas the 1792151 is obsolete and subject to supply discontinuation.

Compliance Certifications: The 1098172 meets ROHS3 compliance requirements, representing current regulatory standards. Both parts maintain EAR99 export classification and identical HTSUS commodity codes, confirming regulatory alignment.

Functional Compatibility: Identical pitch spacing (7.50mm), position count (7), mounting orientation (horizontal with board), and lever-actuated operation ensure direct PCB integration without layout modifications. Both components feature screwless spring-based termination suitable for the same application environments.

Electrical Specifications: The 1098172 provides specified electrical ratings (41 A current, 1000 V voltage) and operating temperature range (-40°C to 105°C), offering defined performance parameters absent from the 1792151 documentation.

Frequently Asked Questions (FAQ)

Q: Can the 1098172 be used as a direct replacement for the 1792151 without PCB modifications?

A: Yes. Both components share identical pitch (7.50mm), position count (7), mounting type (through hole), and mating orientation (horizontal with board). PCB footprints are compatible without layout changes.

Q: What are the wire gauge differences between these parts?

A: The 1792151 accommodates 10-24 AWG wire, while the 1098172 accepts 8-22 AWG wire. The 1098172 supports smaller gauge conductors (8 AWG) but has a lower upper limit (22 AWG versus 24 AWG). Applications using wire within the 10-22 AWG range are fully compatible with both parts.

Q: Why is the 1098172 preferred over the 1792151?

A: The 1098172 is an active product with defined electrical ratings, current compliance certifications (ROHS3), and specified operating temperature range. The 1792151 is obsolete, limiting future procurement availability and manufacturer support.

Q: Are the termination methods equivalent?

A: Both parts use screwless spring-based wire termination with lever actuation. The 1792151 uses spring cage tension clamp termination, while the 1098172 uses leg spring push-in spring termination. Both methods provide secure, tool-free wire connection suitable for the same applications.

Q: What is the packaging difference?

A: The 1792151 packaging is not specified in available documentation. The 1098172 is supplied in bulk packaging, standard for terminal block distribution.

Q: Are moisture sensitivity levels the same?

A: Yes. Both components carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
