Molex 0387008708 Equivalent & Substitute Parts

Part Overview

The Molex 0387008708 is an 8-circuit barrier block connector with 0.325" (8.26mm) pitch, designed for through-hole mounting applications requiring 20A current capacity at 300V. This component features screws with captive plate termination on the top and PC pin termination on the bottom, with dual-wall barrier construction for circuit isolation.

The 0387008708 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0387008708 is determined by the following critical parameters:

• Terminal block type (Barrier Block)
• Number of circuits (8)
• Pitch specification (0.325" / 8.26mm)
• Current rating (20A minimum)
• Voltage rating (300V minimum)
• Termination style (Screws with Captive Plate top, PC Pin bottom)
• Barrier construction (Dual-wall)
• Mounting configuration (Through Hole)
• Wire gauge compatibility (12-22 AWG or broader range)

The substitute part Molex 0387007508 meets all critical substitution criteria. It maintains identical circuit count, pitch, current and voltage ratings, termination styles, and mounting configuration. The substitute part is classified as active product status with expanded wire gauge support (14-22 AWG) and enhanced operating temperature range (-40°C to 130°C versus 110°C maximum for the original part).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0387007508 is the direct substitute for the obsolete 0387008708. Both parts maintain identical electrical and mechanical specifications for circuit count, pitch, current capacity, voltage rating, and termination configuration. The substitute part is currently in active production status with significantly higher inventory availability (5907 units versus 758 units for the original part).

The substitute part provides enhanced operating temperature capability (-40°C to 130°C versus 110°C maximum), supporting a broader range of thermal environments. Both parts maintain ROHS3 compliance and equivalent insulation material specifications. The wire gauge range of the substitute part (14-22 AWG) is narrower than the original (12-22 AWG), which may require verification if applications require 12 AWG wire termination.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387007508 be used as a direct replacement for the 0387008708?

A: Yes. The substitute part maintains identical circuit count (8), pitch (0.325"), current rating (20A), voltage rating (300V), termination styles, and mounting configuration. Both parts are from the same Beau 38700 series and feature dual-wall barrier construction.

Q: What is the difference in wire gauge compatibility?

A: The original 0387008708 supports 12-22 AWG wire, while the substitute 0387007508 supports 14-22 AWG wire. Applications requiring 12 AWG termination must retain the original part number.

Q: How do the operating temperature ranges differ?

A: The original part operates to 110°C maximum. The substitute part operates across -40°C to 130°C, providing enhanced thermal performance for both high and low temperature environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0387008708 and 0387007508 are ROHS3 compliant.

Q: What is the packaging difference?

A: The original part is supplied in standard packaging. The substitute part is supplied in bulk packaging, which may affect procurement and handling procedures.

Q: Why is the substitute part recommended despite the narrower wire gauge range?

A: The substitute part is in active production with superior inventory availability and extended operating temperature range. The narrower wire gauge range (14-22 AWG versus 12-22 AWG) affects only applications requiring 12 AWG termination.
