S-303H-CCT Equivalent & Substitute Parts

Part Overview

The S-303H-CCT is a 3-position socket Jones connector with solder eyelet termination, manufactured by Cinch Connectivity Solutions. This connector is rated for 250 V and 10 A, featuring a phenolic insulation body with phosphor bronze tin-finished contacts. The product status is obsolete, necessitating evaluation of alternative parts for continued application support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of blade type power connectors requires alignment on the following critical parameters: connector type (Jones socket), mounting configuration (free hanging in-line), termination method (solder eyelet), voltage and current ratings, contact materials, and insulation properties. The S-2406H-CCT is grouped as a potential substitute based on shared mechanical interface, termination compatibility, and electrical performance characteristics that exceed or match the original specification. However, the increase in position count (3 to 6) and row configuration (1 to 2 rows) represents a functional design change that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The S-2406H-CCT represents an active product alternative with equivalent mechanical and electrical performance characteristics. Both connectors meet RoHS compliance requirements and share identical voltage ratings, operating temperature limits, contact materials, and termination methods. The S-2406H-CCT provides increased current capacity (15 A versus 10 A) and additional contact positions (6 versus 3) with a 2-row configuration, positioning it as a higher-capacity variant within the same product family. Selection of the S-2406H-CCT requires confirmation that the increased position count and row layout align with circuit topology and available PCB or panel space.

Frequently Asked Questions (FAQ)

Can S-2406H-CCT be used as a direct mechanical replacement for S-303H-CCT? Both connectors share identical mounting type (free hanging in-line), termination method (solder eyelet), and fastening mechanism (push-pull). However, the S-2406H-CCT features 6 positions in a 2-row configuration compared to the 3-position single-row layout of the S-303H-CCT. Direct substitution requires physical layout verification to confirm PCB or panel compatibility.

What are the electrical differences between these parts? Both connectors operate at 250 V and 105°C maximum temperature. The S-303H-CCT is rated for 10 A per contact, while the S-2406H-CCT is rated for 15 A. The increased current capacity does not restrict use in lower-current applications but does not mandate its selection unless higher current delivery is required.

What is the significance of the product status difference? The S-303H-CCT is marked as obsolete, indicating discontinued manufacture. The S-2406H-CCT maintains active product status, ensuring continued availability, technical support, and consistency with future supply-chain requirements.

Are there packaging considerations for procurement? The S-303H-CCT is listed without specified packaging. The S-2406H-CCT is supplied in bulk packaging. Confirmation of minimum order quantities and lead times is necessary for procurement planning.

Do both parts meet the same compliance standards? Both connectors are RoHS compliant and carry EAR99 ECCN classification. Compliance profiles are equivalent with respect to the provided specification data.
