Molex 0545481470 FFC/FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0545481470 is a 14-position FFC/FPC connector with 0.5mm pitch, designed for surface mount right-angle applications. This connector features a flip lock mechanism, zero insertion force (ZIF) design, and is rated for 50V and 0.5A operation across -20°C to 85°C. The product is currently obsolete, making equivalent substitutes necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0545481470 is determined by the following critical parameters that must remain consistent:

• Position Count & Pitch: 14 positions at 0.5mm pitch (0.020") are mandatory for mechanical and electrical compatibility
• Mounting Configuration: Surface mount, right-angle orientation required for PCB layout compatibility
• Electrical Ratings: Minimum 50V voltage rating and 0.5A current rating to meet or exceed original specifications
• FFC/FCB Thickness: 0.30mm thickness ensures proper cable interface compatibility
• Termination Method: Solder termination required for assembly process compatibility
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating maintain regulatory and safety requirements

The Hirose Electric FH34SRJ-14S-0.5SH(50) qualifies as a functional substitute based on these parameters. While it introduces design improvements (gold contact finish, extended temperature range, rotary lock mechanism), the core electrical and mechanical specifications remain compatible with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Hirose Electric FH34SRJ-14S-0.5SH(50) is a qualified substitute for the obsolete Molex 0545481470 based on the following engineering criteria:

Electrical Compatibility: Both connectors maintain identical voltage (50V) and current (0.5A) ratings, ensuring no degradation of electrical performance in the application circuit.

Mechanical Compatibility: Position count (14), pitch (0.5mm), mounting orientation (surface mount right-angle), and FFC thickness (0.30mm) are identical, confirming mechanical interchangeability in PCB layouts.

Regulatory Compliance: Both parts meet UL94 V-0 flammability standards and RoHS compliance requirements, maintaining regulatory status for the end application.

Product Status Advantage: The Hirose substitute is active production status with 2100 units in stock, providing supply chain continuity compared to the obsolete Molex part.

Design Improvements: The Hirose connector offers extended operating temperature range (-55°C to 105°C versus -20°C to 85°C), lower profile height (1.00mm versus 1.20mm), and gold contact finish, which may provide performance benefits in demanding environments without requiring design modifications.

Packaging Consideration: The Hirose part is supplied in Tape & Reel format, suitable for automated assembly processes, whereas the original Molex part was supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the Hirose FH34SRJ-14S-0.5SH(50) be used as a direct replacement for the Molex 0545481470?

A: Yes. Both connectors share identical position count (14), pitch (0.5mm), mounting type (surface mount right-angle), voltage rating (50V), current rating (0.5A), and FFC thickness (0.30mm). The electrical and mechanical specifications are compatible for direct substitution.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Hirose offers extended operating temperature range (-55°C to 105°C versus -20°C to 85°C); (2) Hirose has lower profile height (1.00mm versus 1.20mm); (3) Hirose uses gold contact finish versus tin bismuth; (4) Hirose features rotary lock and backlock mechanisms versus flip lock; (5) Hirose is supplied in Tape & Reel packaging versus bulk; (6) Hirose is active production status versus obsolete.

Q: Will the lower profile height of the Hirose connector affect PCB layout?

A: The Hirose connector is 0.20mm lower in profile (1.00mm versus 1.20mm). This difference is typically negligible for most applications and may provide additional clearance benefits. However, verify that your specific PCB layout and component placement do not depend on the original height specification.

Q: Are both connectors RoHS compliant?

A: Yes. The Molex 0545481470 is ROHS3 compliant, and the Hirose FH34SRJ-14S-0.5SH(50) is RoHS compliant. Both meet regulatory requirements for restricted substance compliance.

Q: What is the difference between "Contacts, Bottom" and "Contacts, Top and Bottom"?

A: The Molex connector has contacts on the bottom side only, while the Hirose connector has contacts on both top and bottom. For FFC/FPC applications, this refers to the contact arrangement on the connector housing. The Hirose design provides additional contact configuration flexibility without affecting compatibility with standard FFC cables.

Q: Does the Hirose connector require any design modifications to the PCB?

A: No design modifications are required. The identical pitch (0.5mm), position count (14), and mounting type (surface mount right-angle) ensure that the Hirose connector fits existing PCB footprints designed for the Molex part.

Q: What is the inventory status for these connectors?

A: The Molex 0545481470 has 887 units in stock but is obsolete. The Hirose FH34SRJ-14S-0.5SH(50) has 2100 units in stock and is active production status, providing superior long-term supply chain availability.
