Molex 0747540825 SFP+ Ganged Cage Connector – Equivalent & Substitute Parts

Part Overview

The Molex 0747540825 is a Position SFP+ Cage connector with ganged (1 x 8) configuration, featuring a light pipe and belonging to the 74754 series. This component is classified as Obsolete, which necessitates identification of active equivalent or substitute parts for new designs and ongoing production requirements. The obsolete status means the part is no longer manufactured or supported by Molex, making substitution essential for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0747540825 is determined by the following core parameters that must remain consistent:

• Connector Type: SFP+ (optical transceiver interface standard)
• Connector Style: Cage, Ganged (1 x 8) configuration
• Series: 74754 (Molex product family)
• Base Product Number: 074754 (common platform)
• Features: Light Pipe functionality

The substitute part identified maintains these critical parameters while offering an active product status. Differences in mounting type (Through Hole, Right Angle) and termination method (Press-Fit) represent design variations within the same functional family and do not preclude substitution when mechanical and electrical integration requirements align with the application.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0747548825 is the designated substitute for the obsolete 0747540825 based on the following engineering criteria:

Product Status: The 0747540825 is classified as Obsolete, rendering it unavailable for new procurement. The 0747548825 maintains Active product status, ensuring ongoing availability and manufacturer support.

Compliance & Certifications: Both parts maintain ROHS3 compliance and share identical Moisture Sensitivity Level classification (Not Applicable), confirming equivalent environmental and regulatory standing.

Functional Equivalence: Both connectors maintain the SFP+ connector type, ganged (1 x 8) cage configuration, and 74754 series designation. The substitute retains the light pipe feature while adding EMI shielding, which provides enhanced electromagnetic interference protection without compromising the core SFP+ interface function.

Design Variation: The substitute introduces Through Hole, Right Angle mounting with Press-Fit termination, representing a mechanical design evolution within the 74754 platform. These variations require validation against specific printed circuit board layout and assembly process requirements but do not alter the electrical interface or optical transceiver compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0747548825 directly replace the 0747540825 in existing designs?

A: The 0747548825 maintains electrical and optical interface compatibility as an SFP+ connector within the 74754 series. However, the Through Hole, Right Angle mounting and Press-Fit termination differ from the original part specification. PCB layout, mounting hole pattern, and assembly process compatibility must be evaluated before implementation.

Q: What is the significance of the EMI Shielding feature added to the substitute part?

A: The 0747548825 includes EMI shielding in addition to the light pipe feature present in the original part. This enhancement provides improved electromagnetic interference rejection and is compatible with SFP+ transceiver operation. The addition does not degrade performance in applications where EMI shielding is not required.

Q: Are both parts ROHS3 compliant?

A: Yes, both the 0747540825 and 0747548825 are ROHS3 compliant, confirming equivalent environmental and regulatory status for applications subject to ROHS3 requirements.

Q: Why is the original part classified as Obsolete?

A: The 0747540825 has reached end-of-life status within Molex's product portfolio. The 0747548825 represents the active continuation within the 74754 series, incorporating design refinements including EMI shielding and press-fit termination technology.

Q: What is the difference between the mounting types specified?

A: The original part does not specify a mounting type in the provided documentation. The substitute specifies Through Hole, Right Angle mounting with Press-Fit termination, indicating a specific mechanical integration approach. Verification of PCB design compatibility is required for substitution in existing applications.

Q: Are there inventory considerations for these parts?

A: The 0747540825 shows 795 pieces in stock as new original inventory. The 0747548825 shows 839 pieces in stock. However, the obsolete status of the original part means existing inventory will not be replenished, making transition to the active substitute necessary for long-term supply chain continuity.
