4DB-P108-10 Equivalent & Substitute Parts

Part Overview

The 4DB-P108-10 is a 10-circuit barrier block connector manufactured by TE Connectivity AMP Connectors. This through-hole terminal block features a 0.325" (8.26mm) pitch with screws and captive plate top termination and PC pin bottom termination. The component is rated for 20A at 150V and accommodates wire gauges from 12-22 AWG. The product maintains active status with RoHS compliance and UL94 V-0 flammability rating.

Substitute parts are identified when equivalent terminal blocks share the same core functional parameters: 10-circuit configuration, 0.325" pitch, barrier block type with dual-wall construction, through-hole mounting, and compatible termination methods. Identifying substitutes ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4DB-P108-10 is determined by the following core parameters:

Critical Matching Parameters:

• Terminal block type: Barrier block
• Number of circuits: 10
• Pitch: 0.325" (8.26mm)
• Number of rows: 1
• Barrier construction: 2 Wall (Dual)
• Bottom termination: PC Pin
• Mounting type: Through hole
• Operating temperature: 105°C
• Flammability rating: UL94 V-0

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed application requirements
• Voltage rating: Substitute must meet or exceed application requirements
• Wire gauge range: Substitute must accommodate the required wire sizes
• Top termination style: Screw-based termination methods are functionally equivalent
• Insulation material: Alternative thermoplastic materials with equivalent performance characteristics
• RoHS compliance status: Both RoHS and ROHS3 compliant parts are acceptable

The 325111-10-0 manufactured by Curtis Industries satisfies all critical matching parameters and operates within allowable variation ranges for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the 4DB-P108-10 and 325111-10-0 are active products with current manufacturing status and full compliance certifications. Selection between these components is based on application-specific electrical requirements.

4DB-P108-10 Selection Criteria:

• Applications requiring 20A current capacity
• Systems operating at 150V nominal voltage
• Designs utilizing 12 AWG minimum wire gauge
• Installations requiring captive plate screw termination

325111-10-0 Selection Criteria:

• Applications with 15A maximum current requirements
• Systems operating at 300V nominal voltage
• Designs utilizing 14 AWG minimum wire gauge
• Installations where standard screw termination is acceptable

Both components maintain UL94 V-0 flammability certification, unlimited moisture sensitivity rating, and 105°C operating temperature specification. The 325111-10-0 provides higher voltage rating capability, while the 4DB-P108-10 provides higher current capacity. RoHS compliance is maintained across both options with equivalent environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the 325111-10-0 replace the 4DB-P108-10 in all applications?

A: The 325111-10-0 is functionally equivalent for applications operating at 15A or below and 300V or below. Applications requiring the full 20A capacity of the 4DB-P108-10 must use the original part number. Wire gauge compatibility requires verification: the 325111-10-0 accommodates 14-22 AWG, while the 4DB-P108-10 accommodates 12-22 AWG.

Q: What are the physical compatibility considerations?

A: Both components share identical pitch (0.325"), circuit count (10), row configuration (1), and through-hole mounting type. Physical board layout compatibility is maintained. The captive plate feature on the 4DB-P108-10 differs from standard screw termination on the 325111-10-0; installation procedures may require adjustment.

Q: Are there compliance differences between these parts?

A: Both parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level. The 4DB-P108-10 carries RoHS Compliant status, while the 325111-10-0 carries ROHS3 Compliant status. Both meet current environmental and regulatory standards for their respective manufacturing dates.

Q: What determines substitution eligibility for barrier block terminal strips?

A: Substitution is determined by matching circuit count, pitch, barrier type, termination method compatibility, and mounting configuration. Electrical parameters (current and voltage ratings) must meet or exceed application requirements. Operating temperature and flammability ratings must be equivalent or superior.

Q: Can wire gauge differences affect substitution decisions?

A: Yes. The 4DB-P108-10 accommodates 12-22 AWG wire, while the 325111-10-0 accommodates 14-22 AWG wire. Applications using 12 AWG wire require the 4DB-P108-10. Applications using 14 AWG or larger wire are compatible with both parts.

Q: How do current ratings affect part selection?

A: Current rating represents the maximum continuous current the terminal block can safely conduct. The 4DB-P108-10 is rated for 20A, while the 325111-10-0 is rated for 15A. Applications requiring currents between 15A and 20A must use the 4DB-P108-10. Applications operating at 15A or below can use either part.
