Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1073555 qualifies as a substitute for the 3244148 based on the following alignment of critical parameters:

Matching Parameters:

• Manufacturer: Phoenix Contact (same manufacturer ensures design compatibility)
• Category: Terminal Blocks (identical product category)
• Type: Ground, Earth (same functional purpose)
• Number of Positions: 2 (identical connector configuration)
• Number of Levels: 1 (identical level structure)
• Termination Style: Push In, Spring (identical connection method)
• Terminal Width: 5.2 mm (identical mechanical interface)
• Material - Insulation: Polyamide (PA), Nylon (identical material composition)
• Material Flammability Rating: UL94 V-0 (identical safety certification)
• Color: Green, Yellow (identical color coding)
• RoHS Status: RoHS Compliant (equivalent environmental compliance)

Acceptable Parameter Variance:

• Wire Gauge Range: 1073555 supports 12-26 AWG (0.14-4 mm²) versus 3244148 at 12-28 AWG (0.08-4 mm²). The 1073555 covers the upper range of the original specification with a narrower lower bound, suitable for applications not requiring 28 AWG capacity.
• Stripping Length: 1073555 specifies 8-10 mm versus 3244148 at 8 mm. The expanded range accommodates standard installation practices.
• Series: 1073555 belongs to CLIPLINE MPT series versus 3244148 in CLIPLINE ST series. Both are Phoenix Contact CLIPLINE platform products with compatible mechanical and electrical interfaces.
• Product Status: 1073555 is Active (current production) versus 3244148 as Last Time Buy (discontinued), making it the appropriate long-term replacement.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1073555 is the appropriate substitute for the discontinued 3244148 based on the following engineering criteria:

Product Continuity: The 1073555 maintains Active production status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of the 3244148.

Functional Equivalence: Both components share identical core specifications: 2-position ground terminal block configuration, 5.2 mm terminal width, push-in spring termination, and UL94 V-0 flammability rating. These parameters define the functional interface and safety performance of the connector.

Compliance Alignment: Both parts are RoHS Compliant, meeting current environmental and regulatory requirements for electronic component procurement.

Wire Gauge Compatibility: The 1073555 supports 12-26 AWG, which encompasses the majority of the original 3244148 specification range (12-28 AWG). Applications requiring 28 AWG termination should be evaluated against actual circuit requirements, as 26 AWG represents a common upper practical limit for ground terminal block applications.

Material and Safety Specifications: Identical polyamide insulation material and UL94 V-0 flammability rating ensure equivalent thermal and electrical safety performance in ground circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 1073555 directly replace the 3244148 in existing designs?

A: Yes, for applications using wire gauges 12-26 AWG. The 1073555 maintains identical mechanical interfaces (5.2 mm terminal width), termination method (push-in spring), and electrical safety ratings (UL94 V-0). If the original design specifically requires 28 AWG termination capability, the application should be reviewed to confirm whether 26 AWG meets the circuit requirements.

Q: What is the difference between the CLIPLINE ST and CLIPLINE MPT series?

A: Both are Phoenix Contact CLIPLINE platform terminal block series. The 1073555 (CLIPLINE MPT) is the current production equivalent to the 3244148 (CLIPLINE ST). The MPT series represents the active product line continuation with compatible mechanical and electrical interfaces.

Q: Are there any installation differences between these two parts?

A: The stripping length specification differs slightly: 3244148 requires 8 mm, while 1073555 allows 8-10 mm. This expanded tolerance in the 1073555 accommodates standard installation practices without affecting performance. Both use identical push-in spring termination methods.

Q: Is the 1073555 suitable for new system designs?

A: Yes. The 1073555 is the recommended choice for new designs requiring 2-position ground terminal blocks with push-in spring termination. Its Active production status ensures availability and supply chain continuity.

Q: What should be considered if my application requires 28 AWG capability?

A: The 1073555 supports wire gauges down to 12 AWG and up to 26 AWG. If 28 AWG termination is essential to the application, alternative Phoenix Contact ground terminal block models should be evaluated. However, for most ground circuit applications, 26 AWG represents adequate capacity.

Q: Are both parts RoHS Compliant?

A: Yes. Both the 3244148 and 1073555 are RoHS Compliant, meeting current environmental regulations for electronic component procurement and assembly.
