Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 5033082451 is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Plug, Outer Shroud Contacts)
• Electrical position count (24 positions)
• Contact pitch (0.016" / 0.40mm)
• Row configuration (2 rows)
• Surface mount assembly compatibility
• Contact material and finish specification (Gold, 4.00µin thickness)
• Physical envelope (mated stacking height and height above board)
• Assembly process compatibility (Pick and Place, Solder Retention)

The substitute part 5033082452 meets all these criteria and is therefore functionally equivalent for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5033082452 is the direct substitute for the obsolete 5033082451. Both parts are manufactured by Molex within the same SlimStack 503308 series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and packaging format. The 5033082451 is obsolete, while the 5033082452 maintains active product status with Tape & Reel packaging, which is standard for high-volume surface mount production environments. The 5033082452 is suitable for new designs and ongoing production support where the 5033082451 is no longer available through normal distribution channels.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the 5033082452 be used as a direct replacement for the 5033082451 in existing designs?

A: Yes. The 5033082452 is electrically and mechanically equivalent to the 5033082451 across all specified parameters, including connector type, position count, pitch, mounting configuration, contact finish, and physical envelope. Direct substitution is supported without design modification.

Q: What is the difference between these two part numbers?

A: The 5033082451 is obsolete and supplied in bulk packaging. The 5033082452 is the active equivalent, supplied in Tape & Reel format optimized for automated pick-and-place assembly. All functional specifications are identical.

Q: Does the Tape & Reel packaging of the 5033082452 affect compatibility?

A: No. Tape & Reel packaging is a supply format that supports automated assembly processes. The connector itself is identical to the bulk-packaged version. The packaging format does not affect electrical or mechanical performance.

Q: Are there any moisture sensitivity considerations for these parts?

A: The 5033082451 has vendor-undefined MSL classification. The 5033082452 is classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. This represents an improvement in handling and storage flexibility for the active substitute part.

Q: Can inventory of the 5033082451 be mixed with the 5033082452 in production?

A: Yes. Both parts are functionally identical and can be used interchangeably in the same assembly process without affecting performance or reliability.
