Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 2-1546720-7 are identified based on electrical and mechanical parameter equivalence. The following critical parameters must match or exceed the original specification for functional substitution:

Electrical Parameters (Must Match):

• Number of circuits: 15
• Pitch spacing: 0.375" (9.53mm)
• Current rating: 20A minimum
• Voltage rating: 300V minimum
• Wire gauge acceptance: 12-22 AWG
• Terminal block type: Barrier block configuration
• Barrier construction: 2-wall (dual) barrier

Mechanical Parameters (Must Match):

• Top termination: Screw-based connection
• Bottom termination: PC pin configuration
• Number of rows: 1
• Flammability rating: UL94 V-0 minimum

Compliance Parameters (Must Match or Exceed):

• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts may differ in mounting type (through-hole versus chassis/panel), operating temperature rating, terminal screw finish specifications, and insulation material composition, provided all critical electrical and mechanical parameters remain equivalent or superior.

Engineering Selection Recommendations

TE Connectivity 2-1546720-7 Selection Criteria:

• Primary choice for applications requiring through-hole, right-angle mounting with 105°C maximum operating temperature
• Specified when original equipment design calls for TE Connectivity AMP Connector series compatibility
• Appropriate for standard industrial control applications within 105°C thermal envelope
• RoHS compliant for regulated markets

Curtis Industries CBP-15 Selection Criteria:

• Suitable as functional equivalent where higher operating temperature rating (140°C) is required
• Applicable for chassis or panel mounting configurations in addition to through-hole options
• Provides ROHS3 compliance status for enhanced regulatory alignment
• Maintains all critical electrical and mechanical parameters equivalent to the original specification
• Supports procurement flexibility and inventory optimization

Both parts maintain active product status, identical electrical ratings, equivalent barrier block construction, and full compliance with UL94 V-0 flammability and MSL-1 moisture sensitivity requirements. Selection between these parts depends on mounting configuration requirements and thermal operating environment specifications.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries CBP-15 directly replace the TE Connectivity 2-1546720-7 in existing designs?

A: The Curtis Industries CBP-15 is electrically and mechanically equivalent for all critical parameters: 15 circuits, 0.375" pitch, 20A current rating, 300V voltage rating, 12-22 AWG wire gauge acceptance, dual-wall barrier construction, screw-top termination, and PC pin bottom termination. Direct substitution is supported for applications where the mounting type (chassis, panel, or through-hole) is compatible with the target PCB or enclosure design. Verify mounting hole spacing and orientation before implementation.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Operating temperature rating—CBP-15 supports 140°C versus 105°C for the 2-1546720-7; (2) Mounting type—CBP-15 offers chassis/panel mounting in addition to through-hole, while 2-1546720-7 is through-hole right-angle only; (3) Insulation material—CBP-15 uses polyester thermoplastic versus thermoplastic for 2-1546720-7; (4) RoHS status—CBP-15 is ROHS3 compliant versus RoHS compliant for 2-1546720-7; (5) Terminal screw finish—2-1546720-7 specifies zinc finish, CBP-15 does not specify finish. All electrical parameters and barrier construction remain identical.

Q: Are there any compatibility concerns with PCB footprints?

A: Both parts feature identical pitch spacing (0.375" / 9.53mm), single-row configuration, and PC pin bottom termination. PCB footprints designed for the 2-1546720-7 will accommodate the CBP-15 without modification. However, mounting type differences must be verified: the 2-1546720-7 is right-angle through-hole only, while the CBP-15 supports multiple mounting configurations. Confirm that the target PCB layout supports the selected mounting orientation.

Q: Which part should be selected for high-temperature applications?

A: The Curtis Industries CBP-15 is specified for applications requiring continuous operation at temperatures up to 140°C. The TE Connectivity 2-1546720-7 is rated to 105°C maximum. For thermal environments exceeding 105°C, the CBP-15 is the appropriate selection.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 2-1546720-7 is RoHS compliant. The Curtis Industries CBP-15 is ROHS3 compliant, which represents an enhanced compliance status. Both parts meet RoHS requirements for regulated markets.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL-1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.

Q: Can these parts be used interchangeably in the same application?

A: Electrical and mechanical interchangeability is confirmed for all critical parameters. Functional interchangeability depends on mounting type compatibility with the target application. If the application requires through-hole right-angle mounting only, both parts are interchangeable. If the application requires chassis or panel mounting options, the CBP-15 provides additional flexibility. Verify mounting configuration requirements before selection.
