AYF323115 FPC Connector Equivalent & Substitute Parts

Part Overview

The AYF323115 is a 31-position flat flexible connector (FPC) manufactured by Panasonic Electric Works, designed for surface mount, right-angle applications with 0.30mm pitch contacts. This connector features bottom contact configuration with zero insertion force (ZIF) operation and flip lock mechanism. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and production requirements. Substitute parts must maintain compatibility across electrical ratings, mechanical dimensions, and termination specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AYF323115 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Pitch: 0.012" (0.30mm)
• Number of Positions: 31
• Mounting Type: Surface Mount, Right Angle
• Voltage Rating: 50V
• Current Rating: 0.2A per Contact
• Operating Temperature Range: -55°C ~ 85°C
• Material Flammability Rating: UL94 V-0
• Height Above Board: 0.035" (0.88mm)
• Termination: Solder
• Contact Material: Copper Alloy
• Contact Finish: Gold
• Housing Material: Liquid Crystal Polymer (LCP)
• Actuator Material: Liquid Crystal Polymer (LCP)

Allowable Variations:

• Connector/Contact Type: Bottom contacts (main part) may be substituted with Top and Bottom contacts (substitute parts) as this represents an enhancement in contact accessibility
• Locking Feature: Flip Lock (main part) may be substituted with Flip Lock + Backlock (substitute parts) as backlock provides additional retention
• Product Status: Obsolete parts may be substituted with Active status parts
• Mating Cycles: Reduction from 30 to 20 cycles is acceptable for equivalent functionality
• Packaging: Different packaging formats (Tape & Reel, Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility

Parameter Comparison

Engineering Selection Recommendations

AYF333135 (Primary Substitute)

The AYF333135 is the direct equivalent for the AYF323115. Both parts maintain identical position count (31), pitch (0.30mm), voltage rating (50V), current rating (0.2A per contact), and operating temperature range (-55°C ~ 85°C). The AYF333135 is currently in active production status with RoHS compliance certification, ensuring long-term availability and regulatory alignment. The enhanced locking feature (Flip Lock + Backlock) provides improved retention without compromising mechanical compatibility. This part is suitable for direct replacement in new designs and production continuity.

AYF332335 (Secondary Substitute)

The AYF332335 shares the same pitch (0.30mm), mounting configuration, voltage rating (50V), current rating (0.2A per contact), and operating temperature range as the AYF323115. However, this part features 23 positions instead of 31, making it suitable only for applications where the connector footprint can accommodate a reduced position count. The AYF332335 is in active production with RoHS3 compliance. This part is not recommended as a direct replacement but may serve as an alternative for redesigned applications with lower pin count requirements.

Frequently Asked Questions (FAQ)

Q: Can AYF333135 directly replace AYF323115 in existing designs?

A: Yes. The AYF333135 maintains all critical electrical and mechanical parameters: 31 positions, 0.30mm pitch, 50V voltage rating, 0.2A per contact current rating, -55°C to 85°C operating temperature, and 0.035" height above board. The enhanced locking mechanism (addition of backlock) is a functional improvement that does not compromise compatibility.

Q: Why is AYF332335 listed as a substitute if it has only 23 positions?

A: The AYF332335 meets all electrical and mechanical specifications (pitch, voltage, current, temperature, height) but differs in position count. It is listed as a substitute for applications where design modification to accommodate 23 positions is feasible. Direct replacement is not possible without PCB redesign.

Q: What is the difference between bottom contacts and top-and-bottom contacts?

A: The AYF323115 features bottom contact configuration only. The substitute parts (AYF332335 and AYF333135) feature both top and bottom contacts, providing dual-sided contact accessibility. This represents an enhancement in connector design without reducing compatibility.

Q: Are there compliance differences between the main part and substitutes?

A: The AYF323115 is obsolete with REACH Unaffected status. Both substitute parts are active production items with REACH Unaffected status. The AYF333135 carries RoHS compliance certification, and the AYF332335 carries RoHS3 compliance certification, ensuring regulatory alignment for current manufacturing standards.

Q: What packaging options are available for the substitute parts?

A: The AYF332335 is supplied in Tape & Reel (TR) packaging. The AYF333135 is supplied in Cut Tape (CT) & Digi-Reel® packaging. Packaging format does not affect electrical or mechanical performance and is selected based on production volume and handling requirements.

Q: Is the reduction in mating cycles from 30 to 20 significant?

A: The AYF323115 specifies 30 mating cycles, while both substitute parts specify 20 mating cycles. This reduction is acceptable for applications where the connector is not subjected to frequent mating and unmating cycles during normal operation. For high-cycle applications, this parameter should be evaluated against specific use case requirements.
