Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF9-51S-1V(59) is determined by strict equivalence across the following critical parameters:

• Connector type and shroud configuration (Receptacle, Outer Shroud Contacts)
• Position count and row configuration (51 positions, 2 rows)
• Contact pitch (1.00mm)
• Mounting technology (Surface Mount)
• Contact finish material (Gold)
• Mechanical envelope (4.3mm mated stacking height, 0.130" height above board)
• Functional features (Board Guide, Solder Retention)

The DF9-51S-1V(69) meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete DF9-51S-1V(59).

Parameter Comparison

Engineering Selection Recommendations

The DF9-51S-1V(69) is the direct substitute for the obsolete DF9-51S-1V(59). Both parts share identical electrical and mechanical specifications within the DF9 series. The primary distinction is product status: DF9-51S-1V(59) is obsolete with limited inventory (649 pcs), while DF9-51S-1V(69) is active with substantial availability (8385 pcs).

For new designs and production continuity, DF9-51S-1V(69) is the appropriate selection. This part offers improved regulatory compliance (ROHS3 Compliant versus RoHS non-compliant) and is supplied in standard Tape & Reel packaging suitable for automated assembly processes. The contact finish thickness specification (8.00µin) is documented for DF9-51S-1V(69), providing additional process control data.

Frequently Asked Questions (FAQ)

Q: Can DF9-51S-1V(69) directly replace DF9-51S-1V(59) in existing designs?

A: Yes. Both parts are functionally equivalent across all critical parameters: 51-position configuration, 1.00mm pitch, 2-row layout, surface mount technology, gold contact finish, and identical mechanical envelope. No design modifications are required.

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

A: The suffix designation (59 versus 69) indicates different manufacturing revisions or packaging configurations within the DF9-51S base product line. The DF9-51S-1V(69) represents the current active production variant.

Q: Why is RoHS compliance different between the two parts?

A: DF9-51S-1V(59) is classified as RoHS non-compliant, reflecting its obsolete status and earlier manufacturing date. DF9-51S-1V(69) is ROHS3 Compliant, meeting current regulatory requirements for new production.

Q: Are there packaging differences?

A: DF9-51S-1V(69) is supplied in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly. The packaging specification for DF9-51S-1V(59) is not documented.

Q: What is the contact finish thickness specification?

A: DF9-51S-1V(69) specifies 8.00µin (0.203µm) gold plating thickness. This specification is not provided for DF9-51S-1V(59).

Q: Are both parts compatible with the same mating connectors?

A: Yes. Both parts are DF9 series receptacles with identical position count, pitch, and shroud configuration, ensuring compatibility with standard DF9 series plug connectors.
