TE Connectivity AMP 4-1734839-6 FPC Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP 4-1734839-6 is a 46-position flat flexible connector (FPC) designed for surface mount, right-angle applications with 0.50mm pitch contacts. This connector features zero insertion force (ZIF) operation, solder retention, and slide lock functionality. The part is currently active in production with 1652 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity AMP 4-1734839-6 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 46
• Pitch: 0.020" (0.50mm)
• Mounting Type: Surface Mount, Right Angle
• Connector/Contact Type: Contacts, Top
• Termination: Solder
• FFC, FCB Thickness: 0.30mm
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Features: Solder Retention, Zero Insertion Force (ZIF)
• Locking Feature: Slide Lock
• Operating Temperature Range: -20°C ~ 85°C
• Material Flammability Rating: UL94 V-0
• Current Rating: 0.5A
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Molex 0541044631 meets all mandatory matching parameters and qualifies as a direct substitute for the TE Connectivity AMP 4-1734839-6.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity AMP 4-1734839-6 and Molex 0541044631 are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent across all critical electrical and mechanical parameters including position count, pitch, mounting configuration, contact materials, and operating temperature range.

The primary difference between the two parts is the voltage rating: the TE Connectivity part is rated for 250V while the Molex part is rated for 50V. Selection between these parts depends on the application voltage requirement. For applications operating at or below 50V, either part is suitable. For applications requiring voltage ratings above 50V, the TE Connectivity AMP 4-1734839-6 is the appropriate choice.

Both parts feature identical current ratings (0.5A), identical moisture sensitivity levels (MSL 1), and identical flammability classifications. The height above board differs by 0.002" (0.05mm), which is negligible for most PCB layout applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0541044631 be used as a direct replacement for the TE Connectivity AMP 4-1734839-6?

A: The Molex 0541044631 qualifies as a substitute for applications operating at 50V or below. Both parts share identical position count (46), pitch (0.50mm), mounting type (surface mount right angle), contact materials (phosphor bronze with gold finish), and operating temperature range (-20°C to 85°C). The critical difference is voltage rating: TE Connectivity is rated 250V while Molex is rated 50V. Confirm your application voltage requirement before substitution.

Q: Are there any PCB layout considerations when switching between these two connectors?

A: The height above board differs by 0.002" (0.05mm) between the parts (TE Connectivity 2.05mm versus Molex 2.00mm). This minimal difference does not typically impact PCB layout or clearance requirements. Both connectors use identical 0.50mm pitch and 46-position configuration, ensuring footprint compatibility.

Q: Do both parts support the same mating cycles?

A: The TE Connectivity AMP 4-1734839-6 does not specify mating cycles in the provided data. The Molex 0541044631 is rated for 20 mating cycles. For applications requiring high-cycle mating reliability, confirm the TE Connectivity part's mating cycle specification through the manufacturer.

Q: What is the significance of the slide lock feature on both connectors?

A: Both connectors incorporate slide lock functionality as part of their zero insertion force (ZIF) design. The slide lock secures the flat flexible cable in position after insertion and prevents accidental disconnection during operation. This feature is standard across both parts.

Q: Are both parts compliant with current environmental regulations?

A: Both the TE Connectivity AMP 4-1734839-6 and Molex 0541044631 are ROHS3 compliant. The TE Connectivity part lists REACH status as vendor undefined, while the Molex part is REACH unaffected. Both parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating.

Q: What termination method is used for both connectors?

A: Both connectors use solder termination with solder retention features. The 0.30mm FFC/FCB thickness specification is identical for both parts, ensuring compatibility with standard solder reflow processes and PCB pad designs.
