Key Parameters

Substitute Part Grouping Explanation

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

• Connector Configuration: 51 positions, 2 rows, 0.039" (1.00mm) pitch
• Connector Type: Header with center strip contacts
• Mounting Technology: Surface mount
• Contact Material: Gold finish
• Mechanical Features: Board guide and solder retention
• Physical Dimensions: Mated stacking height of 4.3mm and height above board of 0.130" (3.30mm)
• Base Product Number: DF9-51P

The DF9-51P-1V(69) qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance, with the substitute part being active and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

The DF9-51P-1V(69) is the direct equivalent for the obsolete DF9-51P-1V(59). Selection of the substitute part is justified on the following grounds:

Product Status: The DF9-51P-1V(59) is obsolete, making the active DF9-51P-1V(69) the appropriate choice for new designs and ongoing procurement.

Regulatory Compliance: The substitute part is RoHS3 compliant, meeting current environmental and regulatory requirements. The main part is RoHS non-compliant, which may present procurement and deployment restrictions depending on application jurisdiction and customer requirements.

Electrical and Mechanical Equivalence: All critical parameters—connector configuration, pitch, contact material, mounting type, and physical dimensions—are identical between the two parts, ensuring direct functional interchangeability.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the DF9-51P-1V(69) be used as a direct replacement for the DF9-51P-1V(59)?

A: Yes. Both parts share identical electrical and mechanical specifications, including 51 positions, 0.039" (1.00mm) pitch, 2-row configuration, gold contact finish, and surface mount technology. The parts are functionally interchangeable.

Q: What is the primary difference between these two parts?

A: The main differences are product status and regulatory compliance. The DF9-51P-1V(59) is obsolete and RoHS non-compliant, while the DF9-51P-1V(69) is active and RoHS3 compliant. The substitute part also specifies contact finish thickness at 8.00µin (0.203µm).

Q: Are there any dimensional or pitch differences?

A: No. Both parts maintain identical mated stacking height (4.3mm), height above board (0.130" / 3.30mm), and pitch (0.039" / 1.00mm).

Q: What packaging format is the substitute part supplied in?

A: The DF9-51P-1V(69) is supplied in Tape & Reel (TR) packaging, suitable for automated surface mount assembly processes.

Q: Are there any moisture sensitivity or environmental compliance differences?

A: Both parts have identical Moisture Sensitivity Level (MSL) of 1 (Unlimited) and REACH Unaffected status. The substitute part meets RoHS3 compliance, which is a regulatory advantage for current applications.
