Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1432826-1 relay is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Coil voltage: 24VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 30A minimum
• Switching voltage: 14VDC nominal
• Coil current: 66.7 mA
• Coil resistance: 360 Ohms
• Operating temperature range: -40°C to 85°C
• Contact material: Silver Tin Oxide (AgSnO)

Mechanical Compatibility Criteria:

• Termination style: Plug In, Quick Connect - 0.250" (6.3mm)
• Coil type: Non Latching
• Relay type: General Purpose

The primary substitute identified is TE Connectivity Potter & Brumfield Relays 1432797-1, which maintains identical electrical specifications and coil parameters. The key difference is the mounting type: the 1432797-1 features chassis mount configuration instead of socketable mounting. This substitution is valid when the application environment permits chassis mount installation in place of socketable mounting.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Socketable Mounting Required): The 1432826-1 is an obsolete component. When socketable mounting is required, the 1432797-1 provides electrical and functional equivalence with the primary difference being mounting configuration. Both parts are ROHS3 compliant and share identical electrical specifications, coil parameters, and contact ratings.

Compliance Considerations: Both the main part and substitute maintain ROHS3 compliance status. The MSL rating of 1 (Unlimited) applies to both components, indicating no moisture sensitivity restrictions during storage or handling.

Inventory and Availability: The 1432797-1 substitute maintains higher inventory availability (6959 pcs) compared to the main part (1036 pcs), supporting long-term supply chain continuity for applications requiring this relay specification.

Frequently Asked Questions (FAQ)

Q: Can the 1432797-1 directly replace the 1432826-1 in all applications?

A: The 1432797-1 provides electrical and functional equivalence. The primary difference is mounting type: 1432797-1 uses chassis mount while 1432826-1 uses socketable mounting. Substitution is valid when the application environment permits chassis mount installation.

Q: What are the critical electrical parameters that must match for substitution?

A: Coil voltage (24VDC), contact form (SPDT), contact rating (30A), coil current (66.7 mA), coil resistance (360 Ohms), and operating temperature range (-40°C to 85°C) must remain identical. Both parts meet these requirements.

Q: Are there differences in termination between these parts?

A: No. Both the 1432826-1 and 1432797-1 use identical termination style: Plug In, Quick Connect - 0.250" (6.3mm).

Q: What is the significance of the VF4 series designation?

A: The VF4 series designation indicates the relay family and base product classification. Both the main part and substitute belong to the same VF4 series, ensuring design compatibility.

Q: Do both parts have the same contact material?

A: Yes. Both parts use Silver Tin Oxide (AgSnO) contact material, ensuring identical switching characteristics and reliability performance.

Q: What is the difference in packaging between these parts?

A: The 1432826-1 is packaged as individual units, while the 1432797-1 is supplied in bulk packaging. This affects inventory management but does not impact electrical or functional performance.

Q: Are there any temperature operating limitations?

A: Both parts operate across the identical temperature range of -40°C to 85°C, with no restrictions or derating requirements within this range.

Q: What does the obsolete product status mean for these parts?

A: Both parts are classified as obsolete, indicating they are no longer in active production. Existing inventory remains available, but long-term supply cannot be guaranteed. The 1432797-1 substitute offers higher current inventory levels.
