Phoenix Contact 1779848 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1779848 is a 3-position terminal block plug with female sockets, 5.00mm pitch, designed for free-hanging in-line applications. This component features screw-type rising cage clamp termination and is rated for 12A (IEC) / 15A (UL) operation at 630V (IEC) / 300V (UL). The part is active in production and ROHS3 compliant, making it suitable for industrial control and power distribution applications where reliable screw-terminated connections are required.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits cross-manufacturer sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1779848 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 3-position configuration with female sockets
• Pitch tolerance: 5.00mm (0.197") or 5.08mm (0.200") are mechanically compatible within standard connector tolerances
• Free-hanging in-line mounting orientation
• Screw-type termination (rising cage clamp or standard screw)
• Wire gauge compatibility: minimum 12 AWG support required
• UL voltage rating minimum 300V
• UL current rating minimum 12A
• ROHS3 compliance and active product status

Identified Substitute Parts:

1. Molex 0395305003 - Pitch 5.08mm, 15A UL, 300V UL, M3 screw, rising cage clamp, active status
2. On Shore Technology OSTTJ037150 - Pitch 5.00mm (exact match), 12-30 AWG support, 300V UL, M3 equivalent, active status
3. On Shore Technology OSTTJ035153 - Pitch 5.08mm, 15A UL, 300V UL, screw termination, active status
4. Amphenol Anytek TJ0351560000G - Pitch 5.08mm, 12A UL, 300V UL, M3 screw, rising cage clamp, active status

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original Phoenix Contact 1779848.

Molex 0395305003 provides the closest functional equivalence with identical rising cage clamp termination, M3 screw specification, and 15A UL current rating. The 5.08mm pitch represents a 0.08mm deviation from the original 5.00mm specification, which falls within standard connector tolerance ranges for mechanical interchangeability.

On Shore Technology OSTTJ037150 offers exact pitch matching at 5.00mm with full wire gauge compatibility (12-30 AWG), making it the preferred choice when pitch precision is critical. Operating temperature range extends to -40°C to 115°C, matching the original specification envelope.

On Shore Technology OSTTJ035153 and Amphenol Anytek TJ0351560000G both support 5.08mm pitch with adequate current and voltage ratings. The Amphenol part maintains rising cage clamp termination and M3 screw specification, while the On Shore OSTTJ035153 provides the highest inventory availability (5960 units) among all substitutes.

Selection should prioritize pitch matching requirements and wire gauge compatibility with the intended application. All substitutes are suitable for direct replacement in applications where the original part is unavailable.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1779848 be directly replaced with a 5.08mm pitch substitute?

A: Yes. The 5.08mm pitch (0.200") substitutes—Molex 0395305003, On Shore OSTTJ035153, and Amphenol TJ0351560000G—are mechanically compatible with the original 5.00mm pitch specification. The 0.08mm pitch difference is within standard connector tolerance ranges and does not affect mating or electrical performance in typical applications.

Q: What is the wire gauge compatibility range across all substitutes?

A: The original Phoenix Contact 1779848 supports 12-30 AWG. Substitute parts support narrower ranges: Molex 0395305003 (12-26 AWG), On Shore OSTTJ037150 (12-30 AWG), On Shore OSTTJ035153 (12-24 AWG), and Amphenol TJ0351560000G (12-24 AWG). Verify wire gauge requirements before substitution.

Q: Are all substitutes rated for the same voltage and current?

A: All substitutes meet the minimum UL requirements of 300V and 12A. The original part and most substitutes are rated 15A UL, except Amphenol TJ0351560000G which is rated 12A UL. For applications requiring 15A operation, confirm the substitute part rating before selection.

Q: Do all substitutes use M3 screws?

A: The Phoenix Contact 1779848, Molex 0395305003, and Amphenol TJ0351560000G all specify M3 screws with 0.56 Nm torque. On Shore Technology parts (OSTTJ037150 and OSTTJ035153) do not specify screw size in the provided data. Verify screw specifications with the manufacturer if M3 compatibility is required.

Q: Which substitute offers the best inventory availability?

A: On Shore Technology OSTTJ035153 has the highest inventory at 5960 units, followed by OSTTJ037150 at 5465 units. Molex 0395305003 has 1991 units, and Amphenol TJ0351560000G has 2913 units available.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and maintain active production status, ensuring regulatory compliance and long-term supply continuity.
