Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity Potter & Brumfield Relays model 1432795-1 qualifies as a substitute for the CB1-D-24V based on the following critical parameters:

Matching Parameters:

• Coil voltage: 24VDC
• Contact form: SPDT (1 Form C)
• Mounting type: Socketable
• Termination style: Plug In, Quick Connect - 0.250" (6.3mm)
• Operating temperature range: -40°C ~ 85°C
• Coil type: Non Latching
• Diode protection: Present
• Must release voltage: 2.4 VDC

Parameter Variations:

• Contact rating: 30A (versus 20A in CB1-D-24V)
• Coil current: 66.7 mA (versus 75 mA)
• Coil resistance: 360 Ohms (versus 320 Ohms)
• Switching voltage: 14VDC Nom (versus 28VDC Nom)
• Operate time: 10 ms (versus 15 ms)
• Contact material: Silver Tin Oxide (AgSnO) (versus Silver Alloy, Cadmium Free)

The 1432795-1 provides higher contact current capacity and faster operation time, making it suitable for applications where the CB1-D-24V was previously specified.

Parameter Comparison

Engineering Selection Recommendations

Both the CB1-D-24V and 1432795-1 are classified as obsolete products. Selection between these relays should be based on application-specific current requirements and timing constraints.

The CB1-D-24V is suitable for applications requiring exactly 20A contact capacity with 15ms operation time. The 1432795-1 provides enhanced current handling at 30A with faster 10ms operation time, offering greater margin for applications with variable load conditions.

The 1432795-1 carries RoHS3 compliance certification, whereas the CB1-D-24V status is not specified. Both parts are REACH unaffected or vendor undefined, and both carry EAR99 export classification.

Socketable mounting and 0.250" quick-connect termination are identical across both models, ensuring mechanical and electrical compatibility in existing socket installations.

Frequently Asked Questions (FAQ)

Q: Can the 1432795-1 directly replace the CB1-D-24V in existing applications?

A: Yes, provided the application does not require the exact 20A contact rating specification. The 1432795-1 offers 30A capacity and faster 10ms operation, making it suitable for most legacy CB1-D-24V installations. Verify that the higher contact capacity and reduced operation time do not conflict with circuit design parameters.

Q: What is the significance of the different contact materials?

A: The CB1-D-24V uses Silver Alloy, Cadmium Free contact material, while the 1432795-1 uses Silver Tin Oxide (AgSnO). Both materials are suitable for general-purpose switching applications. Contact material selection affects arc resistance and contact wear characteristics under specific load conditions.

Q: Are the socketable mounting and termination styles identical?

A: Yes. Both relays feature socketable mounting and Plug In, Quick Connect termination with 0.250" (6.3mm) connectors, ensuring mechanical compatibility in existing relay sockets and harnesses.

Q: What is the difference in coil current between these relays?

A: The CB1-D-24V draws 75 mA, while the 1432795-1 draws 66.7 mA. The lower coil current in the 1432795-1 results in reduced power consumption (1.6W versus 1.8W) and lower heat generation during operation.

Q: Do both relays operate across the same temperature range?

A: Yes. Both the CB1-D-24V and 1432795-1 are rated for -40°C to 85°C operating temperature, ensuring compatibility in automotive and industrial environments with equivalent thermal performance.

Q: What does the obsolete product status mean for component sourcing?

A: Both relays are obsolete, indicating they are no longer manufactured. Sourcing is limited to existing inventory from distributors and component suppliers. Availability may be limited, and long-term supply cannot be guaranteed.
