TE Connectivity AMP 4-1734592-6 FPC Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP 4-1734592-6 is a 46-position flat flexible connector (FPC) designed for surface mount, right-angle applications with 0.50mm pitch contacts. This connector features bottom-contact configuration, zero insertion force (ZIF) operation, and solder termination for PCB integration. The part is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity AMP 4-1734592-6 is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 46
• Pitch: 0.020" (0.50mm)
• Mounting Type: Surface Mount, Right Angle
• Termination: Solder
• FFC, FCB Thickness: 0.30mm
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Liquid Crystal Polymer (LCP)
• Locking Feature: Slide Lock or equivalent
• Features: Solder Retention, Zero Insertion Force (ZIF)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Voltage Rating: Substitute must meet or exceed 250V
• Current Rating: Substitute must meet or exceed 0.5A
• Operating Temperature Range: Substitute must encompass -40°C ~ 85°C

Connector/Contact Type Consideration: The main part features bottom-contact configuration. Substitutes with bottom-contact type provide direct mechanical and electrical compatibility. Substitutes with top-contact configuration require design review for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

GCT FFC2B35-46-G is the primary substitute for TE Connectivity AMP 4-1734592-6. Both connectors feature identical bottom-contact configuration, matching housing material (LCP), and equivalent mechanical dimensions. The GCT part maintains ROHS3 compliance and UL94 V-0 flammability rating. The GCT substitute provides 30 mating cycles, exceeding the Molex alternative. Operating temperature range (-25°C ~ 85°C) encompasses the upper operational boundary of the main part. Voltage rating (50V) and current rating (0.4A) are reduced compared to the original specification; applications requiring the full 250V rating or 0.5A current capacity require evaluation against actual circuit requirements.

Molex 0541044631 is a secondary substitute option. This connector maintains identical position count, pitch, and solder termination. However, the top-contact configuration differs from the bottom-contact main part, requiring PCB layout modification. The Molex part features ZIF operation matching the original specification. Voltage rating (50V) and operating temperature range (-20°C ~ 85°C) present reduced specifications. Current rating (0.5A) matches the original part. Active product status and ROHS3 compliance support long-term availability.

Product Status Consideration: Both substitute parts maintain active product status, ensuring continued availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the GCT FFC2B35-46-G directly replace the TE Connectivity AMP 4-1734592-6 without PCB modification?

A: Yes. Both connectors feature bottom-contact configuration, identical position count (46), matching pitch (0.50mm), and equivalent mechanical mounting specifications. PCB layout remains unchanged.

Q: Why does the Molex 0541044631 require design review despite matching electrical specifications?

A: The Molex part features top-contact configuration, whereas the original part uses bottom-contact configuration. This difference affects PCB trace routing and component placement. Design review ensures compatibility with existing PCB layouts.

Q: Are the voltage and current rating reductions in substitute parts acceptable?

A: The substitute parts specify 50V voltage rating and 0.4A-0.5A current rating, compared to the original 250V and 0.5A. Acceptability depends on actual circuit requirements. Applications operating below 50V and drawing less than 0.4A experience no functional limitation. Applications requiring the full 250V specification require alternative sourcing.

Q: What is the significance of the locking feature difference between parts?

A: The original part uses Slide Lock mechanism. The GCT substitute uses Flip Lock mechanism. Both provide mechanical retention of the flat flexible cable. Flip Lock operation differs from Slide Lock; operator training and assembly procedure documentation require update.

Q: Do all three connectors meet RoHS3 compliance requirements?

A: Yes. The TE Connectivity AMP 4-1734592-6, Molex 0541044631, and GCT FFC2B35-46-G all maintain ROHS3 compliance status. All three parts meet UL94 V-0 flammability rating.

Q: What is the moisture sensitivity level for these connectors?

A: All three connectors specify Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.

Q: How do mating cycle ratings affect component selection?

A: The GCT FFC2B35-46-G specifies 30 mating cycles, and the Molex 0541044631 specifies 20 mating cycles. These ratings indicate the number of connection/disconnection cycles the connector withstands before performance degradation. Applications requiring frequent mating cycles benefit from the higher GCT rating.

Q: Are packaging differences between parts significant for procurement?

A: Both substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original part packaging specification is not provided. Tape & Reel format supports high-volume production environments.
