Key Parameters

Substitute Part Grouping Explanation

The FX2C-20P-1.27DSA(71) qualifies as a direct substitute based on the following matching parameters:

• Identical manufacturer (Hirose Electric Co Ltd)
• Identical series designation (FX2)
• Identical number of positions (20)
• Identical number of rows (2)
• Identical pitch specification (1.27mm)
• Identical connector type (Plug)
• Identical mounting type (Through Hole)
• Identical termination method (Solder)
• Identical application type (Board to Board)
• Identical connector style (Center Strip Contacts)
• Identical contact finish material (Gold)

The primary distinction between the main part and substitute is product status and packaging configuration. The FX2C-20P-1.27DSA(71) is classified as active and supplied in tray packaging, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The FX2C-20P-1.27DSA(71) is the direct substitute for the obsolete FX2C-20P-1.27DSA. Selection of the substitute part is based on:

• Active product status ensuring ongoing manufacturer support and availability
• ROHS3 compliance certification, providing enhanced environmental and regulatory alignment
• Specified contact finish thickness (7.87µin / 0.200µm) offering documented plating specifications
• Tray packaging format suitable for automated assembly and component handling
• Identical electrical and mechanical specifications ensuring form, fit, and function compatibility

Both parts share REACH Unaffected status and EAR99 ECCN classification. The substitute part maintains the same moisture sensitivity level (MSL 1 - Unlimited) as the original.

Frequently Asked Questions (FAQ)

Q: Are FX2C-20P-1.27DSA and FX2C-20P-1.27DSA(71) electrically identical?

A: Yes. Both parts feature identical electrical specifications including 20 positions, 2-row configuration, 1.27mm pitch, gold contact finish, and solder termination. They are functionally equivalent for board-to-board applications.

Q: What is the significance of the "(71)" designation in FX2C-20P-1.27DSA(71)?

A: The "(71)" suffix indicates the tray packaging format and represents the active production variant of the FX2 series connector. This designation distinguishes it from the obsolete base part number.

Q: Does the substitute part fit the same PCB footprint?

A: Yes. The FX2C-20P-1.27DSA(71) maintains identical mounting type (through hole), pitch spacing (1.27mm), and position count (20 in 2 rows), ensuring compatibility with existing PCB designs.

Q: What is the difference in RoHS compliance between the two parts?

A: The original FX2C-20P-1.27DSA is RoHS non-compliant, while the substitute FX2C-20P-1.27DSA(71) is ROHS3 compliant. This provides enhanced environmental compliance for applications subject to RoHS regulations.

Q: Is the contact finish thickness specification important for my application?

A: The substitute part specifies contact finish thickness at 7.87µin (0.200µm). This documented specification provides assurance of plating consistency. The original part does not specify this parameter.

Q: Can I use the substitute part in new designs?

A: Yes. The FX2C-20P-1.27DSA(71) is classified as active and is the recommended choice for new designs requiring a 20-position, 1.27mm pitch board-to-board connector from the FX2 series.
