AYF352525 Equivalent & Substitute Parts

Part Overview

The AYF352525 is a 25-position FPC (Flat Flexible Connector) manufactured by Panasonic Electric Works with 0.3mm pitch spacing, designed for surface mount applications. This connector features solder termination and is classified as obsolete, indicating discontinuation from the manufacturer's active product line. The obsolete status necessitates identification of equivalent substitute components to maintain design continuity and ensure procurement availability for new production runs, repairs, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AYF352525 is based on the following critical parameters that must remain consistent:

Core Electrical & Mechanical Compatibility Criteria:

• Number of Positions: 25
• Pitch: 0.3mm (0.012")
• Connector Category: FPC (Flat Flexible Connector)
• Termination Type: Solder
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)
• Regulatory Classification: ECCN EAR99, HTSUS 8536.69.4051

The AYF332535 qualifies as a substitute based on matching all core parameters. The primary difference is the mounting orientation: the AYF352525 is straight (SMD), while the AYF332535 is right-angle (R/A). This orientation difference does not affect electrical compatibility but requires mechanical layout verification during design integration.

Parameter Comparison

Engineering Selection Recommendations

AYF332535 as Primary Substitute:

The AYF332535 is the active production equivalent for the obsolete AYF352525. Both components share identical electrical specifications (25 positions, 0.3mm pitch, solder termination) and regulatory compliance (EAR99, HTSUS 8536.69.4051, MSL 1). The AYF332535 maintains active product status with Panasonic Electric Works, ensuring long-term availability and supply chain stability.

The primary design consideration is the mounting orientation difference: the AYF352535 uses right-angle mounting versus the straight mounting of the AYF352525. This requires verification of PCB layout compatibility and mechanical clearance in the target application. No electrical redesign is required.

The AYF332535 provides additional documented specifications including 50V voltage rating, 0.2A per contact current rating, operating temperature range of -55°C to 85°C, and RoHS compliance. These specifications support broader application compatibility and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the AYF332535 directly replace the AYF352525 without PCB redesign?

A: Electrical compatibility is confirmed. However, the AYF332535 features right-angle mounting while the AYF352525 is straight-mounted. PCB layout and mechanical clearance must be verified before implementation. If the original design requires straight mounting, layout modification may be necessary.

Q: What is the significance of the obsolete status for the AYF352525?

A: Obsolete status indicates the AYF352525 is no longer manufactured by Panasonic Electric Works. New production orders cannot be fulfilled from the manufacturer. The AYF332535 is the active equivalent and is the recommended substitute for new designs and ongoing production requirements.

Q: Are there electrical performance differences between these connectors?

A: Both connectors share the same core electrical specifications: 25 positions, 0.3mm pitch, and solder termination. The AYF332535 provides documented electrical ratings (50V, 0.2A per contact) and operating temperature range (-55°C to 85°C), which are not specified for the AYF352525. These ratings support the AYF332535 for applications with defined electrical requirements.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 (Unlimited) indicates the lowest moisture sensitivity level. These connectors do not require special moisture control during storage, handling, or assembly. Standard warehouse conditions are acceptable without desiccant packaging or baking procedures.

Q: Is the AYF332535 RoHS compliant?

A: Yes, the AYF332535 is RoHS compliant. This supports applications requiring compliance with RoHS directives and similar environmental regulations.

Q: What is the difference between "Contacts, Top and Bottom" and "Position Connector"?

A: The AYF332535 specifies "Contacts, Top and Bottom," indicating contact access from both sides of the connector. The AYF352525 is described as a "Position Connector" without detailed contact configuration specification. Both are 25-position FPC connectors with identical pitch and termination.

Q: How many mating cycles does the AYF332535 support?

A: The AYF332535 is rated for 20 mating cycles. This specification is not provided for the AYF352525. For applications requiring higher mating cycle counts, this parameter should be evaluated against application requirements.
