Key Parameters

Substitute Part Grouping Explanation

The FX5-20S2A-DSA(71) qualifies as a direct substitute based on the following critical parameters that determine functional and mechanical compatibility:

• Identical connector type (Receptacle, Outer Shroud Contacts)
• Identical number of positions (20)
• Identical pitch (0.039" / 1.00mm)
• Identical number of rows (2)
• Identical mounting type (Through Hole)
• Identical contact finish (Gold)
• Identical height above board (0.366" / 9.30mm)
• Identical moisture sensitivity level (MSL 1)
• Same manufacturer (Hirose Electric Co., Ltd.)
• Same series (FX5)

The primary distinction between the main part and substitute is product status and compliance certification, not electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The FX5-20S2A-DSA(71) is the direct equivalent for the obsolete FX5-20S2A-DSA. Selection of the substitute part is based on the following engineering criteria:

• All electrical and mechanical parameters are identical, ensuring pin-for-pin and form-factor compatibility
• The substitute part maintains active product status, ensuring long-term availability and supply chain reliability
• The substitute part is RoHS compliant, meeting current environmental and regulatory requirements
• Both parts share identical moisture sensitivity classification and environmental ratings
• The substitute part is supplied in tray packaging, suitable for automated assembly processes

Frequently Asked Questions (FAQ)

Q: Are FX5-20S2A-DSA and FX5-20S2A-DSA(71) electrically interchangeable?

A: Yes. Both parts have identical electrical specifications, including contact finish (gold), number of positions (20), pitch (1.00mm), and moisture sensitivity level (MSL 1).

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. compliant), and packaging format. The electrical and mechanical characteristics are identical.

Q: Can I use FX5-20S2A-DSA(71) as a replacement in existing designs?

A: Yes. The substitute part is mechanically and electrically equivalent. The identical pitch, number of positions, mounting type, and height above board ensure direct compatibility with existing PCB layouts and mating connectors.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer. The active equivalent FX5-20S2A-DSA(71) provides continued access to the same connector functionality.

Q: Does packaging affect connector performance?

A: No. Packaging (tray vs. unspecified) affects handling, storage, and assembly logistics but does not alter electrical or mechanical performance.

Q: Are there any compliance differences I should consider?

A: The substitute part is RoHS compliant, while the original is not. For new designs or applications subject to RoHS requirements, the substitute part is the appropriate selection.
