FH3-14S-1.25DS(01) Equivalent & Substitute Parts

Part Overview

The FH3-14S-1.25DS(01) is a 14-position FFC/FPC connector manufactured by Hirose Electric Co Ltd, designed for flat flexible cable applications with top-mounted contacts and right-angle through-hole termination. This connector operates at 0.049" (1.25mm) pitch and is rated for 1A current at 200V. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

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

Position Count & Pitch: The substitute part must have identical position count (14) and pitch (0.049" / 1.25mm) to ensure mechanical and electrical compatibility with the mating FFC/FPC cable.

Mounting Configuration: Both connector type (top-mounted contacts) and mounting method (through-hole, right-angle) must match to ensure proper PCB integration and cable routing.

Electrical Ratings: The substitute must meet or exceed the voltage (200V) and current (1A) requirements of the original circuit design.

Operating Temperature Range: The substitute must support the full operating temperature range (-40°C ~ 85°C) specified for the application.

Contact Material & Finish: Phosphor bronze with tin finish ensures consistent electrical performance and corrosion resistance across substitute parts.

The identified substitute part 1-84533-4 (TE Connectivity AMP Connectors) satisfies all critical substitution criteria within these parameters.

Engineering Selection Recommendations

The 1-84533-4 (TE Connectivity AMP Connectors) is the qualified substitute for the obsolete FH3-14S-1.25DS(01). This substitution is supported by:

Mechanical Compatibility: Identical position count, pitch, mounting type, and contact configuration ensure direct PCB footprint compatibility without redesign.

Electrical Compatibility: Both connectors support 1A current rating and the full -40°C ~ 85°C operating temperature range. The substitute's 50V rating is lower than the original 200V specification; circuit voltage requirements must be verified to confirm adequacy for the application.

Product Availability: The substitute part is in active production status with confirmed inventory (1011 pcs), ensuring long-term procurement viability compared to the obsolete original.

Compliance Enhancement: The substitute achieves RoHS compliance, supporting modern supply chain and regulatory requirements. The glass-filled PBT housing material provides improved mechanical properties over standard PBT.

Termination Difference: The original uses solder termination while the substitute uses kinked pin termination. This difference requires verification of PCB pad design compatibility and soldering process parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1-84533-4 be used as a direct replacement for FH3-14S-1.25DS(01)?

A: Yes, for applications operating at 50V or below. The substitute matches all critical mechanical and electrical parameters (14 positions, 1.25mm pitch, 1A current, -40°C ~ 85°C temperature range). However, the voltage rating difference (50V vs. 200V) must be evaluated against circuit requirements. The kinked pin termination requires PCB pad compatibility verification.

Q: What is the primary reason for substitution?

A: The FH3-14S-1.25DS(01) is obsolete. The 1-84533-4 is an active production part from TE Connectivity, ensuring component availability and supply chain continuity.

Q: Are there packaging differences between these connectors?

A: The original part packaging is not specified in available data. The substitute is supplied in tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Does the substitute meet modern compliance standards?

A: Yes. The 1-84533-4 is RoHS compliant, whereas the original FH3-14S-1.25DS(01) is RoHS non-compliant. This supports compliance with current regulatory requirements.

Q: What is the difference between solder and kinked pin termination?

A: The original uses solder termination for wave or reflow soldering. The substitute uses kinked pin termination, which may require different PCB pad geometry and soldering approach. Verify PCB design compatibility before implementation.

Q: Are the contact materials identical?

A: Yes. Both connectors use phosphor bronze contacts with tin finish, ensuring consistent electrical performance and corrosion resistance.
