Substitute Part Grouping Explanation

Substitution of the TE Connectivity 53408-2 is permissible with part number 1-320551-1 based on the following equivalence criteria:

Matching Parameters (Substitution Basis):

• Terminal Type: Circular
• Stud/Tab Size: 8 Stud
• Wire Gauge: 16-22 AWG
• Termination Method: Crimp
• Insulation: Insulated
• Overall Length: 0.844" (21.44mm)
• Outer Width: 0.312" (7.92mm)
• Thickness: 0.031" (0.79mm)
• Insulation Diameter Range: 0.080" ~ 0.125" (2.03mm ~ 3.18mm)
• Contact Material: Copper
• Mounting Type: Free Hanging (In-Line)
• Series: PIDG
• Product Status: Active

These parameters define the functional and mechanical compatibility required for direct substitution in applications requiring ring terminal connectors with 8-stud circular configuration and 16-22 AWG wire termination capacity.

Engineering Selection Recommendations

Part 53408-2 Selection Criteria:

• Applications requiring Tape & Reel packaging format
• Systems where RoHS non-compliance is acceptable
• Designs requiring Tin-Lead contact finish
• Applications benefiting from PVDF insulation material properties
• Systems requiring radiation-resistant terminal construction

Part 1-320551-1 Selection Criteria:

• Applications requiring ROHS3 compliance certification
• Systems requiring Cut Tape packaging format
• Designs where higher inventory availability is advantageous (6087 pieces versus 955 pieces)
• Applications compatible with Polyamide (PA) nylon insulation material
• Systems requiring Tin contact finish

Both parts maintain identical electrical and mechanical specifications for the 16-22 AWG wire gauge range and 8-stud circular terminal configuration. Selection between these parts is determined by packaging requirements, regulatory compliance mandates, and material composition preferences rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can part 1-320551-1 be used as a direct replacement for 53408-2 in all applications?

A: Part 1-320551-1 is functionally equivalent to 53408-2 for all electrical and mechanical applications involving 16-22 AWG wire termination on 8-stud circular terminals. However, applications with specific RoHS compliance requirements, radiation resistance specifications, or insulation material requirements must be evaluated against the documented differences in contact finish, insulation material, and compliance certifications.

Q: What is the primary difference between these two parts?

A: The primary differences are packaging format (Tape & Reel versus Cut Tape), RoHS compliance status (non-compliant versus ROHS3 compliant), contact finish (Tin-Lead versus Tin), and insulation material (PVDF versus Polyamide/Nylon). All electrical and mechanical parameters remain identical.

Q: Does the change in insulation material from PVDF to Polyamide affect performance?

A: Both PVDF and Polyamide (PA) nylon are suitable insulation materials for ring terminal connectors in the specified wire gauge range. Material selection depends on application-specific environmental and temperature requirements not specified in the provided parameters.

Q: Why does part 1-320551-1 have significantly higher inventory availability?

A: Part 1-320551-1 maintains 6087 pieces in stock compared to 955 pieces for 53408-2. This inventory difference reflects market demand patterns and supply chain management decisions by the manufacturer.

Q: Are there any compatibility issues with the different contact finishes?

A: Both Tin-Lead and Tin contact finishes are standard for copper ring terminal connectors in this category. Compatibility with mating components depends on the specific stud or tab material and finish specifications of the receiving component, which are not provided in the available parameters.

Q: What does the packaging difference mean for procurement?

A: Tape & Reel (TR) packaging is typically used for automated assembly processes, while Cut Tape (CT) packaging is used for manual assembly or lower-volume applications. Selection depends on manufacturing process requirements.
