Molex 5016162575 FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 5016162575 is a 25-position FPC (Flat Flexible Cable) connector with top-mounted contacts, 0.3mm pitch, and right-angle surface mount configuration. This connector is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. The part features zero insertion force (ZIF) operation, flip lock with backlock mechanism, and is rated for 50V at 0.2A with operating temperatures from -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FPC connectors is determined by the following critical parameters:

• Position Count: Must match exactly (25 positions)
• Pitch: Must match exactly (0.3mm)
• Mounting Configuration: Surface mount, right angle orientation
• Termination Type: Solder termination
• Electrical Ratings: Voltage and current ratings must meet or exceed the original specification
• Locking Mechanism: Flip lock functionality for secure cable retention
• Flammability Compliance: UL94 V-0 rating required
• RoHS/REACH Compliance: Environmental regulatory alignment

The Amphenol ICC (FCI) part 10061122-251120HLF qualifies as a functional substitute based on matching position count, pitch, mounting type, termination method, and locking features. However, contact position orientation (bottom vs. top) and specific electrical ratings differ and must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC 10061122-251120HLF presents a viable substitute for the obsolete Molex 5016162575 based on matching mechanical and electrical fundamentals. Both connectors share identical position count, pitch, mounting configuration, and termination method. Both achieve UL94 V-0 flammability compliance and unlimited moisture sensitivity rating.

Key considerations for selection:

Voltage Derating: The Amphenol part carries a 30V rating versus the Molex 50V rating. Applications operating at voltages exceeding 30V require verification that the Amphenol part meets system requirements or alternative substitutes must be evaluated.

Contact Position Orientation: The Molex part features top-mounted contacts while the Amphenol part features bottom-mounted contacts. PCB layout and mating cable configuration must accommodate this geometric difference.

Locking Mechanism: The Molex part includes both flip lock and backlock features, while the Amphenol part includes flip lock only. Applications requiring backlock retention must confirm compatibility with single-lock operation.

Temperature Range: The Amphenol part extends the lower operating limit to -55°C compared to the Molex -40°C minimum, providing broader low-temperature capability.

Regulatory Compliance: Both parts meet RoHS and REACH requirements appropriate for their respective manufacturing dates and regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol 10061122-251120HLF directly replace the Molex 5016162575 on existing PCBs?

A: Direct PCB replacement is not possible without layout modification. The Molex part uses top-mounted contacts while the Amphenol part uses bottom-mounted contacts. PCB trace routing and connector footprint must be redesigned to accommodate the contact position change.

Q: What is the significance of the voltage rating difference (50V vs. 30V)?

A: The voltage rating defines the maximum voltage the connector can safely withstand without risk of electrical breakdown or arcing. Applications operating at voltages between 30V and 50V cannot use the Amphenol part without additional circuit protection or voltage reduction measures.

Q: Are both connectors compatible with the same FPC cable?

A: Both connectors accept 25-position FPC cables with 0.3mm pitch and solder termination. However, cable end geometry (tapered vs. straight) and contact alignment with top vs. bottom mounting must be verified for proper mating.

Q: What does the backlock feature provide that the flip lock does not?

A: Backlock provides secondary mechanical retention that prevents accidental cable withdrawal during vibration or mechanical stress. Applications requiring this additional security must evaluate whether flip lock alone meets reliability requirements.

Q: Are there compliance differences between ROHS3 and RoHS Compliant designations?

A: ROHS3 represents the current EU RoHS Directive 2011/65/EU as amended. RoHS Compliant indicates compliance with RoHS requirements but may reference earlier directive versions. Both parts meet current environmental regulations for their respective manufacturing contexts.

Q: What is the practical difference in operating temperature ranges?

A: The Amphenol part supports operation down to -55°C versus the Molex -40°C minimum. For applications in extreme cold environments, the Amphenol part provides extended low-temperature capability. Both parts support identical maximum temperature of 85°C.
