Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3050044 is determined by the following critical parameters:

Mandatory Matching Parameters:

Number of Positions: 3
Number of Levels: 1
Terminal Width: 5.2 mm
Current Rating (IEC): 17.5 A
Voltage Rating (IEC): 800 V
Current Rating (UL): 10 A
Voltage Rating (UL): 600 V
Material - Insulation: Polyamide (PA), Nylon
Material Flammability Rating: UL94 V-0
Type: Feed Through
Color: Gray

Allowable Variation Parameters:

Wire Gauge Range: Substitute must accommodate the application wire gauge within its specified range
Termination Style: IDC and/or screw termination acceptable
Product Status: Active or Last Time Buy acceptable
RoHS Compliance: RoHS Compliant or ROHS3 Compliant acceptable

The Phoenix Contact 3205048 qualifies as a substitute based on matching all mandatory parameters. The wire gauge range differs (16-24 AWG vs. 12-26 AWG), which represents a narrower specification suitable for applications within the 16-24 AWG overlap range.

Engineering Selection Recommendations

The Phoenix Contact 3205048 is the qualified substitute for the 3050044 terminal block connector. Both components meet identical electrical and mechanical specifications for 3-position, feed-through applications at 17.5 A (IEC) and 800 V (IEC) ratings.

The 3205048 offers the advantage of Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy designation of the 3050044. The 3205048 carries ROHS3 Compliant certification, meeting current regulatory requirements.

The primary consideration for substitution is wire gauge compatibility. The 3050044 accommodates 12-26 AWG, while the 3205048 accommodates 16-24 AWG. For applications requiring wire gauges smaller than 16 AWG or larger than 24 AWG, the 3050044 specifications must be maintained. For applications within the 16-24 AWG range, the 3205048 provides direct substitution.

The 3050044 supports both IDC and screw termination, while the 3205048 supports IDC termination only. Applications requiring screw termination must retain the 3050044 or identify alternative substitutes with screw termination capability.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3205048 directly replace the 3050044 in all applications?

A: Direct substitution is valid for applications using wire gauges within the 16-24 AWG range and requiring IDC termination. Applications using wire gauges outside this range (12-15 AWG or 25-26 AWG) or requiring screw termination must retain the 3050044 or identify alternative components.

Q: What are the key differences between the 3050044 and 3205048?

A: The primary differences are wire gauge range (3050044: 12-26 AWG; 3205048: 16-24 AWG), termination style (3050044: IDC and screw; 3205048: IDC only), series designation (3050044: CLIPLINE QTCU; 3205048: CLIPLINE QTC), and product status (3050044: Last Time Buy; 3205048: Active).

Q: Why is the 3050044 designated as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The 3205048 is the recommended active alternative for new designs and ongoing procurement.

Q: Are the electrical ratings identical between these components?

A: Yes. Both components are rated at 17.5 A (IEC) / 10 A (UL) and 800 V (IEC) / 600 V (UL), with identical insulation material (Polyamide/Nylon) and flammability rating (UL94 V-0).

Q: What is the significance of ROHS3 Compliant versus RoHS Compliant?

A: ROHS3 Compliant indicates compliance with the current Restriction of Hazardous Substances Directive. Both designations confirm the absence of restricted substances; ROHS3 represents the current regulatory standard.

Q: Can the 3205048 be used with screw termination?

A: No. The 3205048 supports IDC termination only. The 3050044 supports both IDC and screw termination methods.
