TE Connectivity AMP 2-1734798-2 FPC Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP 2-1734798-2 is a 22-position flat flexible connector (FPC) designed for surface mount, right-angle applications with 1.00mm pitch contacts. This connector features bottom-mounted contacts, solder termination, and phosphor bronze tin-plated contacts rated for 0.5A at 50V. The component is actively manufactured and RoHS compliant, serving applications requiring reliable FPC interconnection in compact form factors.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, when inventory requirements exceed current stock levels, or when design specifications permit functional equivalents that meet the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FPC connectors is determined by strict alignment of electrical and mechanical parameters that ensure functional compatibility with the mating FPC cable and PCB assembly process. The following parameters establish substitution validity:

Critical Matching Parameters:

• Number of Positions: 22 (contact count must be identical)
• Pitch: 0.039" (1.00mm) (contact spacing must be identical for cable mating)
• Mounting Type: Surface Mount, Right Angle (PCB footprint compatibility)
• Connector/Contact Type: Contacts, Bottom (contact position must match)
• Termination: Solder (assembly process compatibility)
• FFC/FPC Thickness: 0.30mm (cable insertion compatibility)
• Voltage Rating: 50V minimum (electrical safety requirement)
• Current Rating: 0.5A minimum (current capacity requirement)
• Material Flammability Rating: UL94 V-0 (safety compliance)
• RoHS Status: RoHS Compliant (regulatory requirement)

The Hirose Electric FH12-22S-1SH(55) meets all critical matching parameters and qualifies as a functional equivalent substitute for the TE Connectivity AMP 2-1734798-2.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity AMP 2-1734798-2 and Hirose Electric FH12-22S-1SH(55) are active products with current manufacturing status and full compliance certifications. Selection between these parts is based on the following engineering criteria:

TE Connectivity AMP 2-1734798-2 Selection Criteria:

• Primary part availability and established supply chain
• Tin contact finish specification for specific solder compatibility requirements
• Thermoplastic glass-filled housing material requirement
• Standard operating temperature range of -20°C to 85°C
• Established design history and validation in existing applications

Hirose Electric FH12-22S-1SH(55) Selection Criteria:

• Extended operating temperature range (-40°C to 85°C) for low-temperature environments
• Gold contact finish for enhanced corrosion resistance and contact reliability
• Zero Insertion Force (ZIF) feature for simplified assembly and reduced insertion force
• Flip Lock locking mechanism for improved mating security
• Polyamide nylon housing material for specific mechanical property requirements
• Reduced height above board (2.00mm vs 3.20mm) for space-constrained applications
• Higher inventory availability (6,784 pcs vs 878 pcs)

Both parts satisfy the critical electrical and mechanical parameters required for 22-position, 1.00mm pitch FPC connector applications with 50V/0.5A ratings and UL94 V-0 flammability compliance.

Frequently Asked Questions (FAQ)

Q: Can the Hirose Electric FH12-22S-1SH(55) be used as a direct replacement for the TE Connectivity AMP 2-1734798-2?

A: The Hirose Electric FH12-22S-1SH(55) is functionally equivalent for applications requiring 22-position, 1.00mm pitch FPC connectors with solder termination, 50V/0.5A ratings, and UL94 V-0 compliance. Both parts accept 0.30mm thick FPC cables and mount in surface mount right-angle configuration. PCB footprint compatibility is maintained for the critical contact positions. Design validation is required to confirm compatibility with specific application requirements, particularly regarding the reduced height above board (2.00mm vs 3.20mm) and the presence of additional features (ZIF, Flip Lock).

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

A: The primary differences are: (1) Height above board—Hirose is 2.00mm versus TE Connectivity at 3.20mm; (2) Contact finish—Hirose uses gold versus TE Connectivity uses tin; (3) Housing material—Hirose uses polyamide nylon versus TE Connectivity uses thermoplastic glass-filled; (4) Operating temperature range—Hirose extends to -40°C versus TE Connectivity at -20°C; (5) Additional features—Hirose includes Zero Insertion Force (ZIF) and Flip Lock versus TE Connectivity with solder retention only; (6) Mating cycles—Hirose specifies 20 cycles versus TE Connectivity unspecified.

Q: Are there any PCB footprint compatibility concerns?

A: The 22-position 1.00mm pitch contact arrangement is identical between both parts, ensuring contact pad alignment on the PCB. The reduced height above board of the Hirose connector (2.00mm vs 3.20mm) may affect clearance in space-constrained designs. PCB layout review is necessary to confirm adequate clearance for the connector body and any adjacent components.

Q: Which connector should be selected for low-temperature applications?

A: The Hirose Electric FH12-22S-1SH(55) is specified for operation down to -40°C, compared to the TE Connectivity AMP 2-1734798-2 at -20°C. For applications requiring operation below -20°C, the Hirose connector meets the extended temperature specification.

Q: What is the significance of the Zero Insertion Force (ZIF) feature on the Hirose connector?

A: The ZIF feature on the Hirose FH12-22S-1SH(55) reduces the insertion force required to mate the FPC cable, minimizing mechanical stress on the cable and connector contacts during assembly. This feature is not present on the TE Connectivity AMP 2-1734798-2.

Q: Are both connectors RoHS compliant?

A: Yes. The TE Connectivity AMP 2-1734798-2 is RoHS Compliant, and the Hirose Electric FH12-22S-1SH(55) is ROHS3 Compliant. Both meet current RoHS regulatory requirements.

Q: What is the difference between tin and gold contact finishes?

A: Tin contact finish (TE Connectivity) provides cost-effective performance for standard applications with adequate solder wettability. Gold contact finish (Hirose) provides enhanced corrosion resistance, improved contact reliability, and superior performance in high-reliability or harsh environment applications. Gold finish is typically specified for applications requiring extended shelf life or exposure to corrosive environments.

Q: How does packaging affect part selection?

A: The TE Connectivity AMP 2-1734798-2 packaging is not specified in the provided data. The Hirose Electric FH12-22S-1SH(55) is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. Packaging format should be confirmed based on manufacturing assembly requirements and inventory management practices.
