4DB-P208-02 Equivalent & Substitute Parts

Part Overview

The 4DB-P208-02 is a 2-circuit barrier block connector manufactured by TE Connectivity AMP Connectors. This terminal block features a 0.325" (8.26mm) pitch with screw termination and captive plate design, rated for 20A at 150V. The connector is actively produced and widely used in chassis and panel-mounted applications requiring reliable wire-to-board connections.

Substitute parts are identified when equivalent terminal blocks share the same core functional parameters: circuit count, pitch spacing, barrier configuration, and mounting methodology. Alternative sources become necessary due to inventory availability, supply chain considerations, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4DB-P208-02 is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Number of Circuits: 2
• Pitch: 0.325" (8.26mm)
• Terminal Block Type: Barrier Block
• Barrier Type: 2 Wall (Dual)
• Bottom Termination: PC Pin
• Mounting Type: Chassis, Panel; Through Hole
• Number of Rows: 1
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current Rating: Substitute must meet or exceed 20A requirement
• Voltage Rating: Substitute must meet or exceed 150V requirement
• Wire Gauge Range: Substitute must accommodate 12-22 AWG or broader range
• Operating Temperature: Substitute must support -40°C ~ 105°C or broader range
• Top Termination: Screw-based termination acceptable with or without captive plate
• Insulation Material: Thermoplastic or Polypropylene acceptable
• RoHS Status: RoHS Compliant or ROHS3 Compliant acceptable

The substitute part 325011-02-0 (Curtis Industries) meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 4DB-P208-02 (TE Connectivity AMP Connectors)

The 4DB-P208-02 is the specified design component with active product status and full technical documentation. Selection of this part is appropriate for new designs and applications where the 20A current rating and 150V voltage specification are required. The part is RoHS Compliant and carries UL94 V-0 flammability certification, meeting standard industrial safety requirements.

Substitute Part: 325011-02-0 (Curtis Industries)

The 325011-02-0 is functionally equivalent for applications where the following conditions are met:

1. Current Requirement: Application current demand does not exceed 15A. The substitute part is rated for 15A, which is lower than the primary part's 20A rating. Applications requiring the full 20A capacity must use the primary part.

2. Voltage Requirement: The substitute part exceeds the voltage requirement at 300V versus the primary part's 150V, providing additional voltage margin.

3. Wire Gauge Compatibility: Applications using wire gauges 14-22 AWG are compatible with the substitute. Applications requiring 12 AWG wire must use the primary part.

4. Regulatory Compliance: Both parts are UL94 V-0 rated and meet RoHS requirements. The substitute carries ROHS3 Compliant status, representing the updated regulatory standard.

5. Thermal Environment: The substitute part specifies 105°C as an upper operating limit. Applications requiring the full -40°C to 105°C range should confirm the substitute's lower temperature specification with the manufacturer.

6. Mechanical Interface: Both parts feature PC pin bottom termination and through-hole mounting, ensuring PCB compatibility. The primary part includes a captive plate on the screw termination; the substitute features standard screws without captive plate.

Selection between these parts should be based on specific application requirements for current capacity, wire gauge, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can the 325011-02-0 be used as a direct replacement for the 4DB-P208-02 in all applications?

A: No. The 325011-02-0 is functionally equivalent only for applications where current demand does not exceed 15A and wire gauge requirements fall within 14-22 AWG. Applications requiring 20A capacity or 12 AWG wire compatibility must use the 4DB-P208-02.

Q: What is the significance of the 0.325" (8.26mm) pitch specification?

A: Pitch defines the center-to-center spacing between circuits on the connector. Both the primary and substitute parts share identical 0.325" pitch, ensuring they occupy the same PCB footprint and are mechanically interchangeable from a layout perspective.

Q: Why does the substitute part have a higher voltage rating (300V vs. 150V)?

A: Higher voltage ratings indicate the substitute part's insulation and design can safely withstand greater electrical stress. This provides additional safety margin in applications operating at or below 150V. The substitute is suitable for use in 150V applications.

Q: What is the difference between "Screws with Captive Plate" and "Screws"?

A: The captive plate on the primary part prevents screw loss during installation and maintenance. The substitute part uses standard screws without this retention feature. Both termination methods are functionally equivalent for wire connection; the captive plate is a convenience feature.

Q: Are both parts RoHS compliant?

A: Yes. The primary part is RoHS Compliant, and the substitute part is ROHS3 Compliant. ROHS3 represents the updated regulatory standard. Both parts meet hazardous substance restrictions.

Q: What does "2 Wall (Dual) Barrier Type" mean?

A: This specifies that the connector includes two walls of electrical isolation between the two circuits, providing enhanced safety and preventing cross-circuit electrical interference. Both the primary and substitute parts feature this dual-wall barrier configuration.

Q: Can I use 12 AWG wire with the 325011-02-0?

A: No. The substitute part is rated for 14-22 AWG wire. The primary part accommodates 12-22 AWG. Applications requiring 12 AWG wire must use the 4DB-P208-02.

Q: What is the operating temperature range for the 325011-02-0?

A: The provided specification indicates 105°C as the upper operating limit. The lower temperature limit is not specified in the available data. Applications requiring operation below 0°C should confirm the substitute's low-temperature capability with Curtis Industries.

Q: Are the PC pin configurations identical between both parts?

A: Yes. Both parts feature PC pin bottom termination for through-hole PCB mounting. The pin configurations are compatible with standard 0.325" pitch PCB layouts.

Q: What inventory status should I consider when selecting between these parts?

A: The primary part (4DB-P208-02) has 920 pieces in stock. The substitute part (325011-02-0) has 841 pieces in stock. Both are available in bulk packaging. Inventory availability should be evaluated based on project timeline and volume requirements.
