4DB-W208-09 Equivalent & Substitute Parts

Part Overview

The 4DB-W208-09 is a 9-circuit barrier block connector manufactured by TE Connectivity AMP Connectors. This terminal block features a 0.325" (8.26mm) pitch with screw termination on the top and wire wrap termination on the bottom. The connector is rated for 20A at 150V and accommodates wire gauges from 12-22 AWG. The product is currently active and available in inventory with 1163 pieces in stock.

Substitute parts are identified when equivalent terminal blocks share the same core functional characteristics: circuit count, pitch spacing, barrier type, mounting configuration, and termination method. Alternative models may be necessary due to inventory availability, supply chain considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4DB-W208-09 are identified based on strict equivalence in the following core parameters:

• Circuit Configuration: 9 circuits with single-row arrangement
• Pitch Spacing: 0.325" (8.26mm) center-to-center spacing
• Barrier Architecture: 2-wall (dual) barrier design
• Termination Method: Screw-based top termination with wire wrap bottom termination
• Mounting Configuration: Chassis and panel mounting with through-hole design
• Flammability Compliance: UL94 V-0 rating

The substitute part 325021-09-0 from Curtis Industries meets all these core functional requirements. Variations in current rating, voltage rating, wire gauge range, insulation material, and temperature specifications are within acceptable substitution parameters for this terminal block category.

Engineering Selection Recommendations

4DB-W208-09 (Primary Selection)

The 4DB-W208-09 is the primary specification for applications requiring 20A current capacity at 150V. This part is actively manufactured and maintained by TE Connectivity AMP Connectors with full RoHS compliance. The connector supports wire gauges from 12-22 AWG and operates across the temperature range of -40°C to 105°C. The captive plate screw termination provides enhanced assembly security.

325021-09-0 (Substitute Selection)

The 325021-09-0 from Curtis Industries serves as a functional substitute when the primary part is unavailable. This connector is rated for 15A at 300V, providing higher voltage capability while maintaining the same circuit configuration and pitch spacing. The substitute accommodates wire gauges from 14-22 AWG and achieves ROHS3 compliance. The insulation material differs (polypropylene versus thermoplastic), but both materials meet UL94 V-0 flammability requirements.

Selection between these parts depends on application voltage and current requirements. Applications operating below 15A and requiring voltage ratings up to 300V can utilize the Curtis Industries substitute. Applications requiring the full 20A capacity must use the TE Connectivity primary part.

Frequently Asked Questions (FAQ)

Q: Can the 325021-09-0 be used as a direct replacement for the 4DB-W208-09?

A: The 325021-09-0 is functionally equivalent in circuit count, pitch, barrier type, and mounting configuration. However, the current rating differs: 15A versus 20A. Direct substitution is valid only for applications operating at or below 15A. Applications requiring 20A current capacity require the 4DB-W208-09.

Q: What are the key differences between these two barrier block connectors?

A: The primary differences are current rating (20A vs. 15A), voltage rating (150V vs. 300V), wire gauge range (12-22 AWG vs. 14-22 AWG), insulation material (thermoplastic vs. polypropylene), and screw termination design (captive plate vs. standard). Both connectors share identical circuit count, pitch, barrier type, and flammability rating.

Q: Are both parts RoHS compliant?

A: Yes. The 4DB-W208-09 is RoHS compliant, and the 325021-09-0 is ROHS3 compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 4DB-W208-09 and 325021-09-0 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Can 12 AWG wire be used with the 325021-09-0?

A: No. The 325021-09-0 accommodates wire gauges from 14-22 AWG. The 4DB-W208-09 supports 12-22 AWG. Applications requiring 12 AWG wire must use the TE Connectivity part.

Q: What is the operating temperature range for both connectors?

A: Both the 4DB-W208-09 and 325021-09-0 operate across the temperature range of -40°C to 105°C.

Q: How do the packaging options differ?

A: The 4DB-W208-09 packaging specification is not defined in the available data. The 325021-09-0 is supplied in bulk packaging. Confirm packaging requirements with the supplier for the primary part.
