Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Keystone Electronics 1671 is determined by strict alignment with the following critical parameters:

• Connector type: Tip Plug
• Gender: Male
• Plug/mating plug diameter: Standard Tip
• Mounting configuration: Free Hanging (In-Line)
• Termination method: Solderless
• Insulation configuration: Non-Mating End Insulated
• Contact material: Brass
• Contact finish: Nickel
• Body material: Polyamide (PA66), Nylon 6/6
• Color: Black
• RoHS compliance: ROHS3 Compliant

The Cinch Connectivity Solutions Johnson part 105-0303-001 satisfies all mandatory substitution criteria. This part maintains identical mechanical and electrical interface specifications while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Cinch Connectivity Solutions Johnson 105-0303-001 is the direct functional equivalent for the obsolete Keystone Electronics 1671. Both parts maintain identical mechanical interfaces, contact materials, and insulation configurations required for standard tip plug applications.

Selection of the Cinch 105-0303-001 is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance matching the original part specification
• Identical connector geometry and termination method enabling direct substitution
• Equivalent MSL rating (1 - Unlimited) for storage and handling requirements
• Bulk packaging availability supporting production requirements

The operating temperature specification difference (-55°C ~ 85°C for Cinch versus 100°C maximum for Keystone) must be evaluated against actual application requirements. If the application requires operation at temperatures exceeding 85°C, alternative solutions should be investigated.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 105-0303-001 be used as a direct replacement for the Keystone 1671?

A: Yes. Both connectors share identical mechanical interfaces, contact materials (brass with nickel finish), body materials (polyamide PA66), and termination methods (solderless). The connectors are mechanically and electrically interchangeable for standard tip plug applications.

Q: What is the significance of the product status difference?

A: The Keystone 1671 is classified as obsolete, indicating discontinued manufacturing and limited availability. The Cinch 105-0303-001 maintains active product status, ensuring reliable supply chain access and ongoing manufacturer support.

Q: Are there packaging differences between these parts?

A: The Keystone 1671 is supplied in standard packaging, while the Cinch 105-0303-001 is available in bulk packaging. Bulk packaging is suitable for production environments and high-volume applications.

Q: How do the operating temperature ranges compare?

A: The Keystone 1671 specifies a maximum operating temperature of 100°C. The Cinch 105-0303-001 specifies an operating range of -55°C to 85°C. Applications requiring sustained operation above 85°C should confirm compatibility with the Cinch part or investigate alternative solutions.

Q: Are both parts RoHS compliant?

A: Yes. Both the Keystone 1671 and Cinch 105-0303-001 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: What does MSL 1 (Unlimited) mean for storage?

A: MSL 1 (Unlimited) indicates that these connectors have no moisture sensitivity limitations. They can be stored indefinitely without special environmental controls or desiccant packaging requirements.
