Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1432797-1 is determined by the following critical parameters:

Primary Substitution Criteria:

• Coil Voltage: 24VDC (exact match required)
• Contact Form: SPDT (1 Form C) (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Termination Style: Quick Connect - 0.250" (6.3mm) (exact match required)
• Coil Type: Non Latching (exact match required)
• Operating Temperature Range: Minimum -40°C ~ 85°C (substitute must meet or exceed)
• Must Operate Voltage: 14 VDC or lower (substitute must meet or be lower)
• Must Release Voltage: 2.4 VDC or lower (substitute must meet or be lower)

Secondary Compatibility Considerations:

• Contact Rating (Current): Substitute minimum 20A acceptable for applications not requiring full 30A capacity
• Switching Voltage: 28VDC nominal acceptable for 24VDC coil applications
• RoHS Compliance: ROHS3 or RoHS Compliant required
• Moisture Sensitivity Level: MSL 1 (Unlimited) required

All substitute parts listed are Panasonic Electric Works CB series relays with active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally compatible with the TE Connectivity 1432797-1 based on matching coil voltage, contact form, mounting configuration, and termination style. The following selection criteria apply:

For Direct Replacement with Minimal System Impact: CB1-M-24V, CB1-SM-24V, CB1F-M-24V, and CB1F-WM-24V are recommended for applications operating within the -40°C to 85°C temperature range. These parts maintain identical operating temperature specifications to the original part and feature sealed construction for environmental protection.

For Extended Temperature Applications: CB1F-T-M-24V and CB1F-T-R-M-24V extend the upper operating temperature limit to 125°C, providing additional thermal margin for high-temperature environments.

For Applications Requiring Resistor Integration: CB1-R-WM-24V, CB1F-R-WM-24V, and CB1F-T-R-M-24V incorporate integrated resistors and are suitable for circuits requiring transient suppression or EMI mitigation.

Product Status Advantage: All substitute parts carry active product status from Panasonic Electric Works, ensuring long-term availability, supply chain continuity, and ongoing manufacturer support. The original TE Connectivity 1432797-1 is classified as obsolete, making substitution necessary for new designs and ongoing production requirements.

Compliance Considerations: All substitute parts maintain RoHS compliance (ROHS3 or RoHS Compliant) and MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and reliability standards equivalent to the original part.

Current Rating Consideration: Substitute parts are rated for 20A continuous contact current, compared to the original 30A rating. Applications requiring the full 30A capacity must evaluate load requirements and confirm that 20A rating is sufficient for the intended circuit.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic CB1 series relays directly replace the TE Connectivity 1432797-1 in existing applications?

A: Yes, all listed Panasonic CB1 series relays are direct replacements for applications operating within the specified temperature range (-40°C to 85°C for standard variants, -40°C to 125°C for CB1F-T variants). The coil voltage, contact form, mounting type, and termination style are identical. However, the contact current rating is reduced from 30A to 20A, requiring verification that the application load does not exceed 20A continuous current.

Q: What is the difference between CB1-M-24V and CB1F-M-24V?

A: Both parts share identical electrical specifications and operating parameters. The primary difference is the sealing feature: CB1-M-24V features fully sealed construction, while CB1F-M-24V features sealed construction with flux protection. CB1F variants are recommended for applications exposed to soldering flux residue or similar contaminants.

Q: Why do some substitute parts have higher coil current (84 mA) compared to the original (66.7 mA)?

A: Parts designated with "-R-" in the part number incorporate integrated resistors for transient suppression. The higher coil current reflects the additional power dissipation in the resistor element. This does not affect compatibility; the 24VDC coil voltage and switching characteristics remain identical.

Q: Are the CB1F-T variants suitable for all applications, or only high-temperature environments?

A: CB1F-T variants are suitable for all applications within their operating range. The extended temperature rating (-40°C to 125°C) provides additional thermal margin and does not restrict use in standard temperature environments. These variants are recommended when thermal headroom or future application expansion to higher temperatures is anticipated.

Q: What is the significance of the "-WM" designation in part numbers like CB1-R-WM-24V?

A: The "-WM" designation indicates specific mechanical or environmental packaging features. All listed parts with "-WM" designation maintain identical electrical specifications and are fully compatible with the original 1432797-1 relay. Selection between "-WM" and non-"-WM" variants should be based on mechanical mounting requirements and environmental protection needs specific to the application.

Q: Is the 15 ms operate and release time of substitute parts acceptable compared to the original 8 ms and 5 ms specifications?

A: The longer switching times of substitute parts (15 ms operate and release) must be evaluated against application timing requirements. Applications with strict timing constraints or high-speed switching requirements should confirm that the 15 ms specification is compatible with system performance. For most general-purpose relay applications, this timing difference is not critical.

Q: Can I use a 20A-rated relay in a circuit designed for 30A?

A: No. The 20A contact rating of substitute parts is the maximum continuous current the relay contacts can safely carry. Using a 20A relay in a 30A circuit exceeds the contact rating and creates risk of contact degradation, arcing, and relay failure. Applications requiring 30A capacity must either use the original TE Connectivity part or identify alternative relays with 30A or higher contact ratings.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are either ROHS3 Compliant or RoHS Compliant, meeting environmental and hazardous substance restrictions. The original TE Connectivity 1432797-1 is ROHS3 Compliant, and all substitutes maintain equivalent or superior compliance status.

Q: What is the advantage of selecting an active product over the obsolete original part?

A: Active product status ensures long-term availability, ongoing manufacturer support, and supply chain continuity. Obsolete parts face increasing scarcity, potential price escalation, and eventual unavailability. All listed Panasonic CB1 series substitutes carry active product status, providing reliable sourcing for current and future production requirements.
