Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AYF534035A is determined by the following critical parameters:

• Position Count: 40 positions (exact match required)
• Pitch: 0.020" (0.50mm) (exact match required)
• Mounting Configuration: Surface mount, right-angle orientation (exact match required)
• Contact Type: Top and bottom contacts (exact match required)
• Voltage Rating: Minimum 50V (equal or higher acceptable)
• Current Rating: Minimum 0.5A per contact (equal or higher acceptable)
• Operating Temperature: Minimum -55°C to 85°C range (equal or wider acceptable)
• Termination: Solder (exact match required)
• Locking Mechanism: Flip lock and backlock features (exact match required)

Substitute parts must maintain mechanical and electrical compatibility within these parameters. Parts meeting these criteria can be directly substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

AYF564035A is the primary substitute for the AYF534035A. Both parts are manufactured by Panasonic Electric Works and share identical electrical specifications (50V voltage rating, -55°C to 85°C operating temperature). The AYF564035A is currently in active production status, ensuring supply chain availability. The primary difference is increased height above board (1.80mm versus 1.00mm) and slightly reduced current rating per contact (0.4A versus 0.5A). Selection of this part is appropriate when PCB clearance accommodates the increased height and circuit current requirements do not exceed 0.4A per contact.

FFC2B28-40-G is a secondary substitute manufactured by GCT. This part maintains identical mechanical configuration (40 positions, 0.50mm pitch, right-angle surface mount) and is in active production. However, electrical specifications are reduced: voltage rating is 30V (versus 50V) and current rating is 0.2A (versus 0.5A). Additionally, the operating temperature range is narrower (-25°C to 85°C versus -55°C to 85°C). Selection of this part is limited to applications where voltage and current requirements are within these reduced specifications and low-temperature operation below -25°C is not required. The FFC2B28-40-G offers the advantage of higher inventory availability (14,986 pieces in stock).

Frequently Asked Questions (FAQ)

Q: Can AYF564035A be used as a direct replacement for AYF534035A?

A: AYF564035A is mechanically and electrically compatible for most applications. The primary consideration is the increased height above board (1.80mm versus 1.00mm). Verify PCB layout clearance before substitution. Current rating per contact is reduced from 0.5A to 0.4A; confirm circuit current requirements do not exceed this limit.

Q: What are the limitations of FFC2B28-40-G as a substitute?

A: FFC2B28-40-G has reduced electrical ratings: 30V maximum voltage (versus 50V) and 0.2A current per contact (versus 0.5A). Operating temperature range is -25°C to 85°C, which does not support operation below -25°C. Use this part only in applications where all electrical and thermal requirements fall within these specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. AYF534035A and AYF564035A are RoHS Compliant. FFC2B28-40-G is ROHS3 Compliant. All parts meet current RoHS requirements.

Q: What is the significance of the height above board difference?

A: Height above board affects PCB layout and component placement density. AYF534035A and FFC2B28-40-G both measure 0.039" (1.00mm), while AYF564035A measures 0.071" (1.80mm). Designs with tight vertical clearance constraints may require the lower-profile options.

Q: How do packaging options differ among these parts?

A: AYF534035A packaging is not specified. AYF564035A is supplied in Strip packaging. FFC2B28-40-G is supplied in Cut Tape (CT) and Digi-Reel packaging. Packaging selection may affect procurement, handling, and assembly processes.

Q: What is the mating cycle rating for these connectors?

A: All three parts (AYF534035A, AYF564035A, and FFC2B28-40-G) are rated for 20 mating cycles, indicating the expected number of connection/disconnection operations before performance degradation.
