P-306-AB Equivalent & Substitute Parts

Part Overview

The P-306-AB is a 6-position blade type power connector manufactured by Cinch Connectivity Solutions, designed for panel mount applications with solder eyelet termination. This Jones connector operates at 250V with a 10A current rating and features a push-pull fastening mechanism. The part is currently in active production status with 896 units in stock.

Locating equivalent and substitute parts becomes necessary when managing inventory across multiple procurement channels, addressing supply chain constraints, or when design flexibility permits the use of functionally compatible alternatives within the same connector series.

Substitute Part Grouping Explanation

The P-306H-AB qualifies as a direct substitute for the P-306-AB based on the following critical parameters that determine functional compatibility:

• Connector Type: Both are Plug, Jones connectors
• Number of Positions: Both feature 6 positions
• Mounting Type: Both are Panel Mount
• Number of Rows: Both have 2 rows
• Termination Method: Both use Solder Eyelet(s)
• Voltage Rating: Both rated at 250 V
• Current Rating: Both rated at 10 A
• Operating Temperature: Both rated to 105°C
• Fastening Type: Both use Push-Pull mechanism
• Contact Material: Both use Brass contacts
• Insulation Material: Both use Phenol Formaldehyde (Phenolic)
• Series: Both belong to the 300 series
• Base Product Number: Both share P-306 base designation

The primary difference between these parts is the contact finish specification: P-306-AB uses Cadmium finish, while P-306H-AB uses Tin finish. This difference does not affect electrical or mechanical compatibility within the connector interface.

Parameter Comparison

Engineering Selection Recommendations

The P-306H-AB serves as a functional equivalent to the P-306-AB for applications where the connector interface requirements are identical. Selection between these parts should be based on regulatory and compliance requirements:

The P-306-AB maintains active product status and is RoHS non-compliant, making it suitable for applications without RoHS mandates or where legacy component specifications are required.

The P-306H-AB is RoHS Compliant with Tin contact finish, positioning it for applications subject to RoHS directives or environmental compliance standards. However, this part carries obsolete product status, indicating discontinued manufacturing and potential long-term availability constraints.

Both parts share identical electrical ratings, mechanical dimensions, and functional specifications within the 300 series Jones connector family. The contact finish difference (Cadmium versus Tin) reflects manufacturing process changes aligned with regulatory evolution but does not alter connector compatibility or performance within specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can P-306H-AB be used as a direct replacement for P-306-AB in existing designs?

A: Yes. Both connectors share identical electrical ratings (250V, 10A), mechanical configuration (6-position, 2-row, panel mount), termination method (solder eyelet), and fastening mechanism (push-pull). The contact finish difference does not affect connector interface compatibility.

Q: What is the significance of the contact finish difference between Cadmium and Tin?

A: Contact finish affects corrosion resistance and environmental compliance. Cadmium finish (P-306-AB) is RoHS non-compliant, while Tin finish (P-306H-AB) is RoHS Compliant. Both finishes maintain electrical conductivity within the specified operating parameters.

Q: Why is P-306H-AB marked as obsolete if it is RoHS Compliant?

A: Obsolete status indicates the manufacturer has discontinued production of this specific part number. This does not affect the functionality of existing inventory but may impact future procurement availability. The P-306-AB remains in active production.

Q: Are there any mechanical or dimensional differences between these connectors?

A: No. Both parts are 6-position, 2-row, panel mount connectors within the 300 series with identical mounting specifications and solder eyelet termination.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For RoHS-compliant applications, P-306H-AB is appropriate despite obsolete status if current inventory is available. For non-RoHS applications, P-306-AB is the active production option.
