Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S-306-LAB is determined by the following critical parameters that define mechanical and electrical compatibility:

Mechanical Compatibility Parameters:

• Connector type: Socket, Jones
• Number of positions: 6
• Number of rows: 2
• Mounting type: Free Hanging (In-Line)
• Termination method: Solder Eyelet(s)
• Fastening type: Push-Pull

Electrical Compatibility Parameters:

• Voltage rating: 250 V (minimum)
• Current rating: 10 A (minimum)
• Contact material: Phosphor Bronze
• Insulation material: Phenol Formaldehyde (Phenolic)
• Operating temperature: 105°C (minimum)

The S-2406H-CCT meets all mechanical compatibility requirements and exceeds electrical specifications, making it a direct functional substitute for the obsolete S-306-LAB.

Parameter Comparison

Engineering Selection Recommendations

The S-2406H-CCT is the direct equivalent for the obsolete S-306-LAB. Both connectors share identical mechanical form factors and core electrical specifications. The S-2406H-CCT provides the following advantages:

Product Status: The S-2406H-CCT maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete S-306-LAB.

Regulatory Compliance: The S-2406H-CCT is RoHS compliant, whereas the S-306-LAB is RoHS non-compliant. This distinction is critical for applications subject to RoHS directives and modern procurement standards.

Electrical Performance: The S-2406H-CCT supports a 15 A current rating, exceeding the 10 A specification of the S-306-LAB. This provides additional design margin for applications operating at or near the original current limits.

Contact Finish: The S-2406H-CCT features tin contact finish compared to the cadmium finish of the S-306-LAB, aligning with contemporary environmental and health standards.

Additional Features: The S-2406H-CCT includes hood and cable clamp features, providing enhanced mechanical protection and cable management compared to the base S-306-LAB configuration.

Frequently Asked Questions (FAQ)

Q: Can the S-2406H-CCT directly replace the S-306-LAB in existing assemblies?

A: Yes. Both connectors are 6-position Jones sockets with identical mechanical mounting (free-hanging, in-line), row configuration (2 rows), and termination method (solder eyelet). The S-2406H-CCT maintains full pin-to-pin compatibility with the S-306-LAB.

Q: What is the difference in current rating between these parts?

A: The S-306-LAB is rated for 10 A, while the S-2406H-CCT is rated for 15 A. The S-2406H-CCT can handle higher current loads, making it suitable for applications requiring the original 10 A specification and those requiring up to 15 A.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance indicates the absence of restricted substances (lead, cadmium, mercury, and others). The S-2406H-CCT's RoHS compliance makes it suitable for applications and markets with regulatory requirements, whereas the S-306-LAB's non-compliance may restrict its use in certain jurisdictions and procurement environments.

Q: What is the significance of the contact finish difference?

A: The S-306-LAB uses cadmium plating, while the S-2406H-CCT uses tin plating. Tin is the modern standard for electronic connectors due to environmental and health considerations. Both finishes provide adequate corrosion resistance for the 250 V, 10-15 A operating range.

Q: Are the hood and cable clamp features on the S-2406H-CCT necessary for compatibility?

A: No. The hood and cable clamp are additional features that enhance mechanical protection and cable management but do not affect electrical or mechanical compatibility. These features are additive and do not prevent the S-2406H-CCT from functioning as a direct replacement.

Q: What packaging is available for the S-2406H-CCT?

A: The S-2406H-CCT is supplied in bulk packaging, suitable for production environments and component integration workflows.
