Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3244151 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of positions: 2
• Number of levels: 1
• Terminal width: 5.2mm
• Housing color: Green, Yellow
• Material insulation: Polyamide (PA), Nylon
• Flammability rating: UL94 V-0

Wire Gauge Compatibility: The main part accepts 12-28 AWG (0.08-4mm²). Substitute parts must support the required wire gauge range for the application. A substitute with a narrower range (such as 12-26 AWG) remains compatible if the application wire gauges fall within the substitute's supported range.

Termination Style: The main part uses spring cage termination. Substitute parts utilizing push-in or spring termination technologies are functionally equivalent for this application category, as both provide secure electrical connection and mechanical retention.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1073761 serves as a direct substitute for the 3244151 based on the following engineering criteria:

Compliance & Certification Alignment: Both parts maintain UL94 V-0 flammability rating and ROHS3 compliance, ensuring regulatory equivalence for applications requiring these certifications.

Functional Equivalence: Both components provide 2-position, single-level terminal block functionality with identical 5.2mm terminal width and matching polyamide nylon insulation material. The housing color specification (green, yellow) is identical across both parts.

Wire Gauge Consideration: The substitute part 1073761 supports 12-26 AWG, which encompasses the majority of the main part's range. Applications utilizing wire gauges between 12-26 AWG experience no functional limitation. Applications requiring 28 AWG wire accommodation must evaluate alternative substitutes or retain the original part number.

Product Status Advantage: The 1073761 maintains Active product status, providing assured long-term availability compared to the Last Time Buy status of the 3244151. This substitution is recommended for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1073761 replace the 3244151 in all applications?

A: The 1073761 is compatible with applications using wire gauges from 12-26 AWG. If your application requires 28 AWG wire accommodation, the 1073761 does not support this specification. Verify your wire gauge requirements before substitution.

Q: What is the difference between spring cage and push-in termination?

A: Both termination styles provide secure electrical connection and mechanical retention. Spring cage termination uses a spring mechanism to grip the wire, while push-in termination uses a similar spring-based mechanism. For this product category, both are functionally equivalent.

Q: Are the physical dimensions compatible between these parts?

A: Both parts share identical terminal width (5.2mm) and housing color specifications. The stripping length differs slightly (8mm for 3244151 versus 8-10mm for 1073761), which does not affect mechanical compatibility in standard mounting applications.

Q: Does the 1073761 meet the same regulatory requirements?

A: Yes. Both parts carry UL94 V-0 flammability rating and ROHS3 compliance, ensuring equivalent regulatory qualification for applications requiring these certifications.

Q: Why is the 3244151 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The 1073761, with Active product status, represents the current production equivalent from Phoenix Contact for this terminal block category.
