Molex 0387006306 Equivalent & Substitute Parts

Part Overview

The Molex 0387006306 is a 6-circuit barrier block connector with 0.325" (8.26mm) pitch, designed for screw-terminated applications with PC pin bottom connections. This Active product is ROHS3 compliant and rated for 15A at 300V with wire gauge compatibility of 14-22 AWG. Equivalent parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or specific mounting and material requirements while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0387006306 are qualified based on the following core parameters that define functional equivalence:

• 6-circuit configuration with 0.325" (8.26mm) pitch spacing
• Barrier block terminal block type with dual-wall barrier construction
• Screw-based top termination with PC pin bottom connection
• Dual-wall (2 Wall) barrier type for circuit isolation
• PC pin mounting interface for PCB integration

The identified substitutes maintain these critical parameters while differing in secondary attributes such as insulation material, flammability rating, mounting options, and operating temperature specifications. All substitutes are Active products with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with current inventory. Selection between the Molex 0387006306 and its substitutes depends on application-specific requirements:

The Curtis Industries 325011-06-0 provides electrical equivalence with identical current and voltage ratings. It offers expanded mounting flexibility through chassis and panel mounting options in addition to through-hole configuration. The polypropylene insulation material and UL94 V-0 flammability rating support applications requiring enhanced flame resistance. Operating temperature is limited to 105°C maximum.

The TE Connectivity 4DB-P107-06 supports higher current capacity at 20A and accommodates larger wire gauges down to 12 AWG. Voltage rating is reduced to 150V. The polyamide nylon insulation with UL94 V-0 rating provides flame resistance suitable for demanding environments. Operating temperature maximum is 105°C. REACH compliance status is vendor-defined and requires verification for regulated applications.

The original Molex 0387006306 maintains the widest operating temperature range (-40°C to 130°C) and highest voltage rating (300V), making it suitable for extreme temperature and high-voltage applications. ROHS3 and REACH Unaffected status provide full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 325011-06-0 directly replace the Molex 0387006306 in all applications?

A: The Curtis Industries part maintains identical circuit count, pitch, current rating, voltage rating, and wire gauge compatibility. The primary difference is the reduced maximum operating temperature (105°C versus 130°C). Direct substitution is valid for applications operating within the 105°C limit. Applications requiring operation above 105°C require the original Molex part.

Q: What is the significance of the different insulation materials?

A: The Molex part uses thermoplastic insulation, the Curtis Industries part uses polypropylene (PP), and the TE Connectivity part uses polyamide (PA) nylon. These materials differ in thermal stability, chemical resistance, and flame characteristics. The Curtis and TE parts both carry UL94 V-0 flammability ratings, indicating superior flame resistance compared to the Molex part. Material selection should align with application environmental conditions and regulatory requirements.

Q: Is the TE Connectivity 4DB-P107-06 suitable for 300V applications?

A: No. The TE Connectivity part is rated for 150V maximum, making it unsuitable for applications requiring 300V operation. The Molex 0387006306 and Curtis Industries 325011-06-0 both support 300V ratings and are appropriate for high-voltage applications.

Q: What mounting flexibility does the Curtis Industries part provide?

A: The Curtis Industries 325011-06-0 supports three mounting configurations: chassis mounting, panel mounting, and through-hole mounting. The Molex and TE Connectivity parts support through-hole mounting only. The additional mounting options provide design flexibility for applications requiring non-standard PCB integration approaches.

Q: Are all three parts RoHS compliant?

A: The Molex 0387006306 and Curtis Industries 325011-06-0 are both ROHS3 compliant. The TE Connectivity 4DB-P107-06 is RoHS compliant. ROHS3 represents the current regulatory standard. Both compliance levels satisfy RoHS requirements; ROHS3 is the more recent designation.

Q: What is the inventory status for each part?

A: Molex 0387006306: 826 pieces in stock. Curtis Industries 325011-06-0: 977 pieces in stock. TE Connectivity 4DB-P107-06: 2297 pieces in stock. All parts are available as new original components in bulk packaging.
