Keystone Electronics 4474 Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 4474 is a 1 Position Boot Connector Female Receptacle with 0.250" (6.35mm) terminal size, designed for quick connect/disconnect applications. The connector features a yellow vinyl boot and is rated for free hanging in-line mounting. This part is classified as obsolete, making identification of suitable substitute components essential for ongoing procurement and system maintenance. The primary reason for seeking alternatives is the discontinued product status, which necessitates sourcing from active inventory to ensure supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Keystone Electronics 4474 is determined by strict alignment with the following critical parameters:

• Terminal Type: Quick Connect, Disconnect
• Gender: Female, Receptacle
• Terminal Size: 0.250" (6.35mm)
• Number of Positions: 1
• Mounting Type: Free Hanging (In-Line)
• Style: Boot
• Material: Vinyl
• RoHS Status: ROHS3 Compliant

The Keystone Electronics 4471 meets all substitution criteria. While the boot color differs (clear versus yellow), this is a cosmetic variation that does not affect electrical or mechanical compatibility. The 4471 maintains identical terminal specifications, connector configuration, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 4471 is the direct substitute for the obsolete Keystone Electronics 4474. Selection of the 4471 is supported by:

• Identical electrical and mechanical specifications across all functional parameters
• Active product status ensuring ongoing availability and supply chain reliability
• Equivalent ROHS3 compliance and regulatory certifications
• Identical terminal configuration, mounting method, and connector interface
• Boot material and style consistency with the original design

The only distinction between the two parts is the boot color (yellow versus clear), which represents a cosmetic variation without impact on electrical performance, mechanical fit, or system functionality. This color difference does not affect connector operation or compatibility with mating components.

Frequently Asked Questions (FAQ)

Q: Can the Keystone 4471 be used as a direct replacement for the Keystone 4474?

A: Yes. The 4471 is functionally equivalent to the 4474 across all electrical and mechanical parameters. Both are 1 Position Boot Connector Female Receptacles with 0.250" (6.35mm) terminal size, identical mounting configuration, and equivalent regulatory compliance.

Q: What is the difference between the Keystone 4474 and 4471?

A: The primary difference is boot color: the 4474 features a yellow boot, while the 4471 features a clear boot. All other specifications—terminal type, size, gender, mounting method, material, and compliance status—are identical.

Q: Why is the Keystone 4474 listed as obsolete?

A: The 4474 has been discontinued by the manufacturer. The Keystone 4471 serves as the active replacement, maintaining full compatibility while ensuring continued product availability.

Q: Are there any compatibility concerns when substituting the 4471 for the 4474?

A: No compatibility concerns exist. Both connectors are designed for 0.250" (6.35mm) quick connect/disconnect applications and maintain identical mechanical and electrical interfaces.

Q: Does the boot color change affect connector performance?

A: No. Boot color is a cosmetic attribute that does not influence electrical performance, mechanical fit, or functional operation of the connector.

Q: What is the packaging difference between these parts?

A: The 4474 was supplied in standard packaging, while the 4471 is supplied in bulk packaging. This does not affect the connector specifications or performance.
