Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1437671-3 is determined by alignment of the following critical parameters:

Mandatory Matching Parameters:

• Positions Per Level: 10
• Pitch: 0.200" (5.08mm)
• Mating Orientation: Horizontal with Board
• Mounting Type: Through Hole
• Current Rating: 10 A minimum
• Voltage Rating: 150 V minimum
• RoHS3 Compliance

Acceptable Parameter Variations:

• Wire Gauge: Substitute may accommodate broader range (14-30 AWG vs. 18-22 AWG)
• Voltage Rating: Substitute may exceed minimum requirement (300 V vs. 150 V)
• Wire Termination: Screw-based termination acceptable as functional equivalent to push-in spring
• Housing Material: Alternative thermoplastic polymers acceptable
• Operating Temperature: Specification dependent on application requirements

The Phoenix Contact 1729209 satisfies all mandatory matching parameters and provides enhanced electrical performance through higher voltage rating and expanded wire gauge compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 1-1437671-3 carries obsolete status, indicating discontinued manufacturing and limited long-term availability. The Phoenix Contact 1729209 maintains active product status with confirmed inventory of 2305 pieces, ensuring supply chain continuity for current and future applications.

Compliance Alignment: Both components achieve ROHS3 compliance and share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, supporting equivalent regulatory and trade documentation requirements.

Electrical Performance: The Phoenix Contact 1729209 provides enhanced electrical specifications with 300 V voltage rating versus the original 150 V specification, delivering additional safety margin in applications operating at or near the original voltage limit. Current rating remains equivalent at 10 A.

Wire Gauge Accommodation: The substitute part accepts 14-30 AWG wire gauge, encompassing the original 18-22 AWG specification while providing flexibility for applications requiring larger or smaller conductor sizes within the terminal block footprint.

Termination Method Transition: The original push-in spring termination transitions to screw-based rising cage clamp termination in the substitute. This change requires assembly procedure modification but maintains equivalent electrical connection reliability and mechanical retention.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1729209 directly replace the TE Connectivity 1-1437671-3 in existing PCB designs?

A: Yes, for PCB footprint compatibility. Both components feature identical 10-position configuration, 0.200" (5.08mm) pitch, and through-hole mounting. Assembly procedures differ due to termination method change from push-in spring to screw-based clamping.

Q: What is the impact of the higher 300 V voltage rating on the Phoenix Contact substitute?

A: The 300 V rating provides enhanced electrical safety margin and permits use in higher voltage applications. Existing 150 V applications operate within the substitute's electrical envelope with no adverse effects.

Q: Does the expanded 14-30 AWG wire gauge range of the substitute create compatibility issues?

A: No. The original 18-22 AWG specification falls within the substitute's 14-30 AWG range. The broader range accommodates additional wire sizes without affecting compatibility with original wire gauge selections.

Q: How does the screw termination method differ from the original push-in spring termination?

A: Push-in spring termination requires wire insertion without tools. Screw termination uses a rising cage clamp mechanism actuated by M3 screw tightening to 0.5-0.6 Nm. Both methods achieve equivalent electrical connection and mechanical retention.

Q: Are there material compatibility concerns between polyester thermoplastic and polyamide housing?

A: Both materials are thermoplastic polymers suitable for terminal block applications. Polyamide (PA) nylon offers equivalent electrical insulation and mechanical properties. Material selection does not affect electrical performance or PCB mounting compatibility.

Q: What is the significance of the REACH Affected status for the Phoenix Contact part?

A: REACH Affected indicates the component may contain substances of concern under EU chemical regulations. This status requires compliance documentation for European market distribution but does not affect component functionality or electrical performance.

Q: Is the MSL 1 (Unlimited) rating identical between both components?

A: Yes. Both components carry MSL 1 rating, indicating unlimited shelf life without moisture sensitivity concerns. No special storage or handling procedures are required for either component.
