Molex 0545501433 FFC/FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0545501433 is a 14-position FFC/FPC connector with 0.5mm pitch, designed for surface mount right-angle applications. This connector features zero insertion force (ZIF) operation, slide lock mechanism, and solder termination. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0545501433 is determined by the following critical parameters:

• Position Count: Must be 14 positions
• Pitch: Must be 0.020" (0.50mm)
• Mounting Configuration: Must be surface mount, right angle
• Termination Method: Must be solder
• Voltage Rating: Must meet or exceed 50V
• Current Rating: Must meet or exceed 0.5A
• Connector Type: Must support FFC/FPC flat flexible cable
• Locking Mechanism: Must provide secure cable retention
• Compliance: Must meet RoHS and UL94 V-0 flammability requirements

The identified substitute parts meet these core electrical and mechanical parameters while maintaining functional compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

Molex 0545501434 is the primary substitute option. As an active Molex product within the same Easy-On 54550 series family, it provides direct compatibility with existing designs. The part maintains the same 14-position, 0.5mm pitch, surface mount right-angle configuration. Selection of this part eliminates supply chain risk associated with the obsolete 0545501433 while preserving design continuity.

Hirose FH34SRJ-14S-0.5SH(50) is a cross-manufacturer substitute that meets all critical electrical and mechanical parameters. This part offers extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C) and gold contact finish for enhanced corrosion resistance. The rotary lock and backlock mechanism differs from the slide lock of the original part but provides equivalent cable retention. Both parts are RoHS compliant and UL94 V-0 rated. The Hirose option is suitable for applications requiring broader temperature performance or enhanced contact durability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0545501434 be used as a direct replacement for the 0545501433?

A: The Molex 0545501434 maintains identical electrical and mechanical specifications for position count, pitch, mounting configuration, and termination method. Both parts are Molex products within the same connector family. Verification of specific design requirements is necessary before implementation.

Q: What are the key differences between the Molex 0545501434 and Hirose FH34SRJ-14S-0.5SH(50)?

A: Both parts share the same 14-position, 0.5mm pitch, surface mount right-angle configuration and 50V/0.5A ratings. Differences include: locking mechanism (slide lock versus rotary lock with backlock), contact finish (tin bismuth versus gold), operating temperature range (-40°C to 85°C versus -55°C to 105°C), and height above board (1.20mm versus 1.00mm). The Hirose part features top and bottom contacts versus top contacts only.

Q: Are there packaging considerations when switching between these parts?

A: The Molex 0545501433 and 0545501434 are both surface mount right-angle connectors with similar footprints. The Hirose FH34SRJ-14S-0.5SH(50) has a slightly lower profile (1.00mm versus 1.20mm height above board). PCB layout verification is required to confirm clearance compatibility, particularly in space-constrained applications.

Q: Do all substitute parts meet the same compliance standards?

A: The Molex 0545501433 is ROHS3 compliant with UL94 V-0 flammability rating. The Hirose FH34SRJ-14S-0.5SH(50) is RoHS compliant with UL94 V-0 rating. Both parts have MSL 1 (unlimited moisture sensitivity). Compliance verification against specific application requirements is necessary.

Q: What is the difference in contact finish between these parts?

A: The Molex 0545501433 uses tin bismuth contact finish (1.00µm thickness). The Hirose FH34SRJ-14S-0.5SH(50) uses gold contact finish (0.050µm thickness). Gold finish provides enhanced corrosion resistance and is suitable for applications with extended storage or high-humidity environments.
