Substitute Part Grouping Explanation

Substitution of the Molex 0465577147 is based on strict electrical and mechanical parameter matching within the SEARAY 46557 series. The substitute part must maintain identical specifications across the following critical parameters:

• Connector type: High Density Array, Female
• Position count: 100 positions
• Pitch: 0.050" (1.27mm)
• Row configuration: 4 rows
• Mounting method: Surface Mount
• Contact finish: Gold at 30.0µin (0.76µm) thickness
• Height above board: 0.199" (5.05mm)
• Mated stacking height range: 7mm through 12mm
• Board guide feature presence
• Compliance certifications: ROHS3, REACH Unaffected

The substitute part 0465577145 meets all these parameters and is classified as active product status, making it a direct parametric equivalent suitable for replacement in new designs and production applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0465577145 is the direct parametric equivalent for the obsolete 0465577147. Both parts are manufactured by Molex within the same SEARAY 46557 series and share identical electrical and mechanical specifications. The primary distinction is product status: 0465577145 is actively manufactured and supported, while 0465577147 is obsolete.

For new designs and ongoing production, the 0465577145 is the appropriate selection. This part maintains full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with current environmental standards. The active product status guarantees continued availability and manufacturer support.

The packaging difference (bulk versus Tape & Reel) reflects standard industry practice for active versus legacy products and does not affect functional compatibility or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 0465577145 be used as a direct replacement for the 0465577147?

A: Yes. Both parts are identical in all electrical and mechanical parameters, including connector type, position count, pitch, mounting method, contact finish, and compliance certifications. The 0465577145 is the active equivalent.

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

A: The primary difference is product status. The 0465577147 is obsolete, while the 0465577145 is actively manufactured. Packaging also differs: the obsolete part is supplied in bulk, while the active part is supplied in Tape & Reel format. All functional specifications are identical.

Q: Are there any compatibility concerns when switching from 0465577147 to 0465577145?

A: No compatibility concerns exist. The parts are parametrically identical and will function identically in the same circuit board layout and mating interface. No design modifications are required.

Q: Does the Tape & Reel packaging of the 0465577145 affect its performance?

A: No. Packaging format is a supply and handling consideration only and does not affect electrical performance, mechanical fit, or functional characteristics of the connector.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 0465577147 and 0465577145 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
