TE Connectivity 4-1734248-0 FPC Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-1734248-0 is a 40-position flat flexible connector (FPC) with vertical, single-sided contacts designed for surface mount applications. This connector features a 1.00mm pitch and is rated for 125V at 1A per contact with zero insertion force (ZIF) operation. The product is classified as obsolete, necessitating identification of equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of FPC connectors is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish substitution eligibility for the 4-1734248-0:

Mandatory Matching Parameters:

• Number of Positions: 40
• Pitch: 0.039" (1.00mm)
• Connector Type: FPC (Flat Flexible)
• Contact Configuration: Vertical - 1 Sided
• Mounting Type: Surface Mount
• Voltage Rating: 125V minimum
• Current Rating: 1A minimum
• Operating Temperature Range: -20°C to +85°C minimum
• Locking Feature: Slide Lock
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Polyamide (PA9T), Nylon 9T
• Flammability Rating: UL94 V-0
• Features: Zero Insertion Force (ZIF)
• Termination: Solder
• FFC Thickness: 0.30mm
• Height Above Board: 0.217" (5.50mm)
• Mating Cycles: 20 minimum

Only components meeting all specified parameters qualify as direct substitutes. Deviations in any parameter eliminate substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 4-1734248-0 is classified as an obsolete product. The parametric equivalent identified (4-1734248-0) is identical across all electrical and mechanical specifications. Both components share the same manufacturer part number and maintain full compatibility with existing designs.

For applications currently utilizing the 4-1734248-0, the parametric equivalent provides direct substitution without design modification. Both components meet UL94 V-0 flammability requirements and operate within the specified temperature range of -20°C to +85°C. The 125V voltage rating and 1A current rating remain consistent across both parts.

Procurement decisions should account for the obsolete status of this connector series. Long-term availability may be limited, and alternative connector architectures from current product lines should be evaluated for new designs requiring FPC connectivity with 40-position, 1.00mm pitch specifications.

Frequently Asked Questions (FAQ)

Q: Can the 4-1734248-0 be replaced with a different pitch FPC connector?

A: No. The 0.039" (1.00mm) pitch is a critical mechanical parameter. Substitution with alternative pitch values (such as 0.05" or 0.02") will result in incompatibility with the mating FPC cable and cannot be used as a direct replacement.

Q: Is the 40-position count flexible for substitution?

A: No. The 40-position configuration is a fixed parameter. Connectors with different position counts (such as 20, 30, or 50 positions) are not compatible and cannot serve as substitutes.

Q: What is the significance of the "Vertical - 1 Sided" contact configuration?

A: This specification indicates that contacts are oriented perpendicular to the PCB surface and are present on a single side of the connector housing. Substitutes must maintain this exact configuration. Horizontal or dual-sided contact arrangements are not compatible.

Q: Does the Surface Mount (SMD) designation affect substitution?

A: Yes. The SMD mounting type specifies solder termination to the PCB. Through-hole or other mounting types cannot be substituted without PCB redesign.

Q: Why is the Slide Lock feature important for substitution?

A: The Slide Lock mechanism provides mechanical retention of the FPC cable within the connector. Substitutes must include this locking feature to ensure cable retention and prevent accidental disconnection during operation.

Q: Can a connector with a higher voltage rating substitute for the 125V rated part?

A: A connector with a voltage rating equal to or greater than 125V meets the electrical requirement. However, all other parameters must remain identical for substitution eligibility.

Q: What does "Zero Insertion Force (ZIF)" mean in the context of substitution?

A: ZIF indicates that the FPC cable can be inserted and removed without applying force to the connector actuator. This feature must be present in any substitute component to maintain operational compatibility.

Q: Is the 0.30mm FFC thickness a critical parameter?

A: Yes. The FFC thickness determines mechanical fit within the connector cavity. Cables with different thicknesses will not seat properly and cannot be used as substitutes.

Q: How does the "Mating Cycles: 20" specification affect substitution?

A: This specification indicates the connector is rated for 20 insertion and removal cycles. Substitute components must meet or exceed this cycle rating to maintain equivalent reliability.

Q: What is the importance of the UL94 V-0 flammability rating?

A: UL94 V-0 certification indicates the housing material meets strict flammability standards. Substitute components must maintain this certification to comply with safety and regulatory requirements.
