AYF333535 FPC Connector - Equivalent & Substitute Parts

Part Overview

The AYF333535 is a 35-position flat flexible connector (FPC) manufactured by Panasonic Electric Works, designed for surface mount, right-angle applications with 0.3mm pitch contacts. This connector features top and bottom contact configuration, gold-plated copper alloy contacts, and is housed in liquid crystal polymer (LCP) material. The product is currently obsolete, making identification of compatible substitute parts essential for legacy system maintenance, repair, and redesign applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AYF333535 is determined by strict equivalence across the following critical parameters:

• Number of Positions: Must be exactly 35 positions
• Pitch: Must be exactly 0.012" (0.30mm)
• Mounting Type: Must be Surface Mount, Right Angle
• Connector/Contact Type: Must be Contacts, Top and Bottom
• Voltage Rating: Must be 50V or higher
• Current Rating: Must support 0.2A per Contact or higher
• Operating Temperature Range: Must encompass -55°C ~ 85°C
• Termination Method: Must be Solder
• Contact Material and Finish: Must be Copper Alloy with Gold finish
• Housing Material: Must be Liquid Crystal Polymer (LCP)
• RoHS Compliance: Must be RoHS Compliant

The identified substitute part AYF333535A meets all critical electrical and mechanical parameters. The primary difference is packaging format (Cut Tape versus Strip), which does not affect functional compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AYF333535A is a direct functional equivalent to the AYF333535. Both parts are manufactured by Panasonic Electric Works, share identical electrical specifications, mechanical dimensions, and material composition. The sole distinction is packaging format: the main part is supplied in Cut Tape (CT) format, while the substitute is supplied in Strip format. This packaging difference does not affect component performance, electrical characteristics, or board-level compatibility.

Both parts carry obsolete product status and are RoHS compliant. Selection between these two parts should be based on procurement requirements and available inventory, as the functional performance and compatibility are equivalent.

Frequently Asked Questions (FAQ)

Q: Can AYF333535A be used as a direct replacement for AYF333535?

A: Yes. The AYF333535A is functionally equivalent across all critical electrical and mechanical parameters. Both parts feature 35 positions, 0.3mm pitch, surface mount right-angle configuration, 50V voltage rating, and 0.2A per contact current rating.

Q: What is the difference between Cut Tape and Strip packaging?

A: Cut Tape (CT) packaging supplies components on individual tape segments, while Strip packaging supplies components on continuous tape. This is a procurement and handling format difference only and does not affect component functionality or performance.

Q: Are both parts RoHS compliant?

A: Yes. Both AYF333535 and AYF333535A are RoHS compliant and suitable for applications requiring lead-free solder and restricted substance compliance.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 85°C, suitable for industrial and commercial temperature environments.

Q: Can these connectors handle the required current for my application?

A: Each contact is rated for 0.2A. Total current capacity depends on the number of active contacts in your application. Verify that individual contact current requirements do not exceed 0.2A per contact.

Q: Why is the AYF333535 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production by the manufacturer. However, inventory remains available through authorized distributors. The AYF333535A provides equivalent functionality for legacy system support and new designs requiring this connector specification.
