Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 2-1546720-8 are identified based on the following critical parameters that determine functional equivalency:

Primary Matching Criteria:

• Number of circuits: 3 positions
• Pitch spacing: 0.375" (9.53mm)
• Mounting configuration: Through Hole
• Bottom termination: PC Pin
• Wire gauge compatibility: 12-22 AWG range
• Voltage rating: Minimum 300V
• Current rating: Minimum 20A
• Flammability compliance: UL94 V-0
• RoHS compliance status

Substitute Categories:

Category 1 - Barrier Block Direct Equivalents: Parts maintaining barrier block terminal block type with identical pitch, circuit count, and PC pin bottom termination. These substitutes provide equivalent or enhanced electrical ratings while maintaining mechanical compatibility.

Category 2 - Wire-to-Board Terminal Blocks: Parts with equivalent pitch, circuit count, and through-hole mounting but utilizing alternative termination technologies (rising cage clamp screw termination). These substitutes provide enhanced current ratings and voltage specifications with compatible wire gauge ranges.

Parameter Comparison

Engineering Selection Recommendations

CB20220307 (Eaton - Electronics Division) is a direct barrier block substitute with identical terminal block type, circuit count, pitch, and PC pin bottom termination. This part provides enhanced current rating (30A versus 20A) and extended operating temperature range (-40°C to 105°C). The captive plate screw design offers improved assembly security. ROHS3 Compliant status and UL94 V-0 flammability rating maintain regulatory equivalency. This substitute is suitable for applications requiring higher current capacity within the same form factor.

1904150 and 1907429 (Phoenix Contact COMBICON MKDS Series) are wire-to-board terminal blocks with equivalent pitch and circuit count but utilize rising cage clamp screw termination technology. Both parts provide enhanced electrical specifications: 30A current rating and 600V voltage rating. Wire gauge compatibility extends to 10-30 AWG, accommodating larger conductor sizes. These substitutes are suitable for applications requiring higher voltage and current specifications. Both maintain RoHS compliance and unlimited moisture sensitivity level (MSL 1). Part 1907429 carries ROHS3 Compliant status.

Product Status Consideration: All substitute parts maintain Active product status, ensuring continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the CB20220307 (Eaton) directly replace the 2-1546720-8 (TE Connectivity)?

A: Yes. Both parts are barrier block terminal connectors with identical 3-circuit configuration, 0.375" (9.53mm) pitch, and PC pin bottom termination. The CB20220307 provides enhanced current rating (30A) and extended temperature range while maintaining mechanical and electrical compatibility. The captive plate screw design is a functional enhancement that does not affect interchangeability.

Q: What is the primary difference between the TE Connectivity 2-1546720-8 and the Phoenix Contact COMBICON MKDS parts?

A: The primary difference is terminal block type and termination technology. The TE Connectivity part is a barrier block with standard screw termination, while the Phoenix Contact parts are wire-to-board terminal blocks with rising cage clamp screw termination. The Phoenix Contact parts provide higher voltage (600V) and current (30A) ratings with extended wire gauge range (10-30 AWG). Mechanical compatibility is maintained through identical pitch and circuit count.

Q: Are the Phoenix Contact 1904150 and 1907429 interchangeable with each other?

A: Yes. Both parts are identical COMBICON MKDS series terminal blocks with 3 positions, 0.375" (9.53mm) pitch, 30A current rating, and 600V voltage rating. The primary difference is RoHS compliance status: 1904150 is RoHS Compliant, while 1907429 is ROHS3 Compliant. Selection depends on regulatory requirements for the specific application.

Q: What wire gauge compatibility should be verified when substituting parts?

A: The original TE Connectivity 2-1546720-8 accepts 12-22 AWG wire. The Eaton CB20220307 maintains this range (12-22 AWG). The Phoenix Contact parts (1904150 and 1907429) accept 10-30 AWG, providing broader compatibility. Verify that the wire gauge of existing installations falls within the substitute part's specified range.

Q: Do all substitute parts maintain the same operating temperature range?

A: No. The TE Connectivity 2-1546720-8 operates to 105°C maximum. The Eaton CB20220307 extends this range to -40°C to 105°C, providing enhanced low-temperature performance. The Phoenix Contact parts do not specify operating temperature in the provided data. Verify temperature requirements for the specific application before selection.

Q: What is the significance of the captive plate feature on the CB20220307?

A: The captive plate on the Eaton CB20220307 secures the screw during assembly, preventing loss and improving assembly efficiency. This is a functional enhancement that does not affect electrical or mechanical compatibility with the original TE Connectivity part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain RoHS compliance status. The TE Connectivity 2-1546720-8 is RoHS Compliant. The Eaton CB20220307 and Phoenix Contact 1907429 are ROHS3 Compliant. The Phoenix Contact 1904150 is RoHS Compliant. Selection depends on specific regulatory requirements for the application.

Q: What is the voltage rating difference between the barrier block and wire-to-board substitutes?

A: The TE Connectivity barrier block (2-1546720-8) and Eaton barrier block (CB20220307) are both rated for 300V. The Phoenix Contact wire-to-board terminal blocks (1904150 and 1907429) are rated for 600V. Applications requiring higher voltage isolation should utilize the Phoenix Contact parts.

Q: Can the 2-1546720-8 be used in applications requiring 30A current?

A: No. The TE Connectivity 2-1546720-8 is rated for 20A maximum. Applications requiring 30A current must utilize the Eaton CB20220307 or Phoenix Contact 1904150/1907429 substitutes, all rated for 30A.

Q: What mounting configuration is required for these terminal blocks?

A: All parts utilize through-hole mounting for PCB installation. The TE Connectivity 2-1546720-8 specifies right-angle orientation. The Eaton CB20220307 and Phoenix Contact parts specify through-hole mounting without specific angle designation. Verify PCB layout compatibility before selection.
