Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX2C1-40P-1.27DSA is determined by strict equivalence across the following critical parameters:

• Number of Positions: 40
• Number of Rows: 2
• Pitch: 1.27mm
• Connector Type: Plug
• Mounting Type: Through Hole
• Termination: Solder
• Connector Style: Center Strip Contacts
• Application Type: Board to Board
• Contact Finish: Gold
• Series: FX2

The FX2C1-40P-1.27DSA(71) meets all these criteria and is classified as a direct substitute. The primary distinction is product status: the original part is obsolete, while the substitute maintains active product status. Additionally, the substitute includes specified contact finish thickness (7.87µin / 0.200µm) and carries RoHS Compliant certification, whereas the original is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The FX2C1-40P-1.27DSA(71) is the direct substitute for the obsolete FX2C1-40P-1.27DSA. Both parts are manufactured by Hirose Electric Co Ltd and share identical electrical and mechanical specifications across all critical parameters.

Selection between these parts should be based on the following factors:

Product Status: The main part is obsolete, limiting long-term availability. The substitute maintains active product status, ensuring continued supply and support.

Compliance Requirements: If RoHS compliance is required for new designs or regulatory adherence, the FX2C1-40P-1.27DSA(71) is the appropriate choice. The original part does not meet RoHS standards.

Packaging: The substitute is supplied in Tray packaging, which may differ from the original part's packaging specification. Verify packaging compatibility with assembly processes if applicable.

Contact Finish Specification: The substitute provides documented contact finish thickness (7.87µin / 0.200µm), offering greater specification clarity compared to the original part.

Frequently Asked Questions (FAQ)

Q: Are FX2C1-40P-1.27DSA and FX2C1-40P-1.27DSA(71) electrically and mechanically identical?

A: Yes. Both parts share identical specifications for number of positions (40), rows (2), pitch (1.27mm), connector type (Plug), mounting type (Through Hole), termination (Solder), connector style (Center Strip Contacts), application type (Board to Board), and contact finish (Gold). They are direct equivalents.

Q: Why is the original part marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, production decisions, and product lifecycle management. The FX2C1-40P-1.27DSA(71) variant is the active replacement.

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

A: The designation "(71)" in FX2C1-40P-1.27DSA(71) indicates a specific variant or revision. The primary functional differences are product status (Active vs. Obsolete), RoHS compliance (Compliant vs. non-compliant), and packaging (Tray vs. unspecified).

Q: Can I use FX2C1-40P-1.27DSA(71) as a direct replacement in existing designs?

A: Yes, provided that RoHS compliance requirements and packaging specifications are compatible with your assembly process. The electrical and mechanical characteristics are identical.

Q: What is the significance of the contact finish thickness specification?

A: Contact finish thickness (7.87µin / 0.200µm) on the substitute part provides documented durability and wear resistance characteristics. This specification is not provided for the original part.

Q: Are there inventory considerations when selecting between these parts?

A: The original part has 1111 units in stock, while the substitute has 717 units available. However, given the obsolete status of the original part, the substitute's active status provides greater long-term availability assurance.
