DF6-4P-3.96C Equivalent & Substitute Parts

Part Overview

The DF6-4P-3.96C is a 4-position rectangular connector housing manufactured by Hirose Electric Co Ltd, designed for board-in mounting applications with a 0.156" (3.96mm) pitch. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The board-in connector type with male pin contact configuration serves as the mating interface in rectangular connector assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF6-4P-3.96C is determined by the following critical parameters that must remain consistent:

• Pitch: 0.156" (3.96mm) — ensures mechanical and electrical compatibility with mating connectors
• Number of Positions: 4 — maintains circuit density and pin count requirements
• Contact Termination: Crimp — preserves assembly process compatibility
• Number of Rows: 1 — maintains single-row configuration

The substitute part DF63-4S-3.96C shares these core parameters. However, the following differences exist and must be evaluated for application suitability:

• Connector Type: DF6-4P-3.96C is Board-In; DF63-4S-3.96C is Socket (Free Hanging In-Line)
• Contact Type: DF6-4P-3.96C uses Male Pin; DF63-4S-3.96C uses Female Socket
• Mounting Type: DF6-4P-3.96C is Board Mount; DF63-4S-3.96C is Free Hanging (In-Line)
• Series: DF6 versus DF63 (EnerBee™)

These differences indicate that DF63-4S-3.96C functions as a mating connector rather than a direct form-fit-function replacement.

Parameter Comparison

Engineering Selection Recommendations

The DF6-4P-3.96C is obsolete; however, direct replacement options within the same form factor and mounting configuration are not provided in the available substitute list. The DF63-4S-3.96C is an active product from the same manufacturer with matching pitch and position count, but functions as a mating connector (socket) rather than a direct substitute.

Selection of DF63-4S-3.96C is appropriate only when the application requires a mating connector assembly. Both parts maintain RoHS compliance and unlimited moisture sensitivity rating (MSL 1). The DF63-4S-3.96C provides enhanced product status (Active) and documented operating temperature range (-55°C ~ 105°C), supporting long-term supply chain stability.

For applications requiring a direct board-in male pin housing replacement, alternative Hirose rectangular connector series or third-party equivalents with identical mounting and contact configurations should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can DF63-4S-3.96C directly replace DF6-4P-3.96C?

A: No. DF63-4S-3.96C is a socket connector designed for free-hanging in-line mounting, while DF6-4P-3.96C is a board-in male pin housing. They share pitch and position specifications but serve different functional roles in connector assemblies.

Q: What parameters must match for substitution compatibility?

A: Pitch (0.156" / 3.96mm), number of positions (4), number of rows (1), and contact termination method (crimp) are the critical parameters determining substitution eligibility within rectangular connector categories.

Q: Why is DF6-4P-3.96C obsolete?

A: Product status is provided as obsolete in manufacturer records. Hirose Electric Co Ltd has transitioned this component to end-of-life status.

Q: Are both parts RoHS compliant?

A: Yes. DF6-4P-3.96C is RoHS Compliant; DF63-4S-3.96C is ROHS3 Compliant. Both meet regulatory requirements for restricted substance limitations.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Does DF63-4S-3.96C include contacts?

A: No. Both DF6-4P-3.96C and DF63-4S-3.96C are housings only; contacts must be procured separately.
