Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Molex 0747541420 is determined by the following critical parameters:

Functional Parameters:

• Connector type: SFP+ cage
• Configuration: 1X4 (ganged, four-position)
• Application: PCI interface
• Termination method: Press-fit

Physical Parameters:

• Mounting orientation: Right angle
• Mounting method: Through hole
• Base product family: 074754 series

Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The substitute part Molex 0747547420 maintains identical functional specifications within the same base product family (074754 series), shares equivalent RoHS and MSL ratings, and provides active product status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0747547420 serves as the direct active equivalent for the obsolete 0747541420. Both components share the same base product family designation (074754 series), identical SFP+ cage configuration (1X4), and equivalent press-fit termination methodology. Both parts maintain RoHS compliance and MSL 1 rating, ensuring compatibility with current environmental and regulatory requirements.

The substitute part is currently in active production status with confirmed inventory availability (1120 pieces), whereas the original part is obsolete with no ongoing manufacturing support. The ECCN classification change from OBSOLETE to EAR99 reflects the active status of the substitute component and does not indicate functional or electrical differences.

Selection of the 0747547420 for new designs and production applications eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing SFP+ cage interface specifications.

Frequently Asked Questions (FAQ)

Q: Are the 0747541420 and 0747547420 electrically identical?

A: Both components function as 1X4 SFP+ cage connectors with press-fit termination. They share the same base product family (074754 series) and maintain equivalent electrical specifications for SFP+ transceiver module interfaces.

Q: What is the primary difference between these two parts?

A: The 0747541420 is classified as obsolete with no active manufacturing support. The 0747547420 is the active equivalent with current production availability and ongoing manufacturer support.

Q: Can the 0747547420 be used as a direct replacement in existing designs?

A: Yes. Both parts maintain identical RoHS compliance, MSL 1 rating, and press-fit through-hole mounting specifications. The 0747547420 is designed as the functional successor within the same product family.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these components have unlimited shelf life under standard storage conditions and do not require special moisture control during handling or storage.

Q: Are there any packaging differences between these parts?

A: Packaging information is not specified in the available technical parameters for either component.

Q: What is the significance of the ECCN classification change?

A: The ECCN classification reflects the active versus obsolete status of the components. The EAR99 classification for the active part indicates standard export control treatment and does not affect functional compatibility or performance characteristics.
