Key Parameters

Substitute Part Grouping Explanation

Substitution of the S-303H-AB is determined by the following critical parameters:

Connector Type: Socket, Jones connectors maintain mechanical and electrical compatibility within the Jones connector family.

Mounting Configuration: Panel mount orientation and flange design must be preserved.

Termination Method: Solder eyelet termination is required for PCB integration.

Electrical Ratings: Voltage rating of 250 V and current rating must meet or exceed the original specification.

Material Composition: Phenol formaldehyde insulation and phosphor bronze contacts with tin finish ensure consistent performance characteristics.

Operating Temperature: 105°C maximum operating temperature establishes the thermal envelope for substitute selection.

Compliance Standards: RoHS compliance status must be maintained for regulatory alignment.

The S-2404H-AB qualifies as a substitute based on these parameters, with the exception of position count and current rating, which represent design enhancements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The S-2404H-AB is available as an active product with current manufacturing support, addressing the obsolescence status of the S-303H-AB. Both connectors maintain identical electrical ratings of 250 V and equivalent operating temperature specifications of 105°C. RoHS compliance is preserved across both parts, ensuring regulatory continuity.

The S-2404H-AB provides enhanced current capacity at 15 A compared to the 10 A rating of the S-303H-AB, representing a design improvement. The increased position count (4 versus 3) and dual-row configuration (2 rows versus 1 row) require mechanical validation to confirm fit within existing panel mount apertures and PCB layouts.

Selection of the S-2404H-AB is supported by its active product status and availability of 901 units in stock, compared to the limited inventory of 747 units for the obsolete S-303H-AB.

Frequently Asked Questions (FAQ)

Q: Can the S-2404H-AB directly replace the S-303H-AB in existing designs?

A: Mechanical compatibility must be verified. The S-2404H-AB features a 2-row, 4-position configuration compared to the 1-row, 3-position design of the S-303H-AB. Panel mount aperture dimensions and PCB footprint must be confirmed before substitution.

Q: Are the electrical characteristics equivalent?

A: Both connectors operate at 250 V. The S-2404H-AB provides 15 A current capacity versus 10 A for the S-303H-AB, representing a performance enhancement. Operating temperature ratings are identical at 105°C.

Q: What compliance certifications apply to both parts?

A: Both the S-303H-AB and S-2404H-AB are RoHS compliant. Both are classified under ECCN EAR99 and HTSUS 8536.69.4030.

Q: Why is the S-303H-AB classified as obsolete?

A: Obsolescence status indicates the part is no longer in active production. The S-2404H-AB represents the current active alternative within the Cinch Connectivity Solutions Jones connector portfolio.

Q: What is the packaging configuration for the S-2404H-AB?

A: The S-2404H-AB is supplied in bulk packaging, compared to the unspecified packaging of the S-303H-AB.
