Key Parameters

Substitute Part Grouping Explanation

The DF12NC(3.0)-10DP-0.5V(51) qualifies as a direct substitute based on the following critical parameters:

• Connector Configuration: Both parts maintain 10 positions in a 2-row arrangement with 0.50mm pitch spacing
• Physical Compatibility: Identical mated stacking height (3mm) and height above board (2.30mm) ensure PCB layout compatibility
• Contact System: Both utilize gold-plated outer shroud contacts for equivalent electrical performance
• Mounting Method: Surface mount configuration is identical
• Environmental Compliance: Both meet RoHS requirements and MSL 1 rating

The primary distinction is product status: the original part is obsolete, while the substitute is active. The substitute part is supplied in Tape & Reel packaging with documented contact finish thickness (8.00µin / 0.203µm) and REACH compliance confirmation.

Parameter Comparison

Engineering Selection Recommendations

The DF12NC(3.0)-10DP-0.5V(51) is the appropriate selection for applications currently specified with DF12D(3.0)-10DP-0.5V(81). Selection rationale:

• Product Lifecycle: The substitute part maintains active status with confirmed inventory availability (4331 pcs), eliminating obsolescence risk
• Regulatory Compliance: Both parts satisfy RoHS requirements; the substitute provides ROHS3 compliance and documented REACH status
• Electrical and Mechanical Equivalence: All critical parameters—connector configuration, pitch, contact system, and stacking height—are identical
• Supply Chain Reliability: Tape & Reel packaging format supports automated assembly processes
• Cost Efficiency: Active product status typically provides superior pricing and lead time compared to obsolete alternatives

No design modifications or PCB layout changes are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable? A: Yes. Both parts share identical pitch (0.50mm), position count (10), row configuration (2), and stacking heights (3mm mated, 2.30mm above board). PCB footprints and mating interface dimensions are equivalent.

Q: What is the difference between the part numbers? A: The primary differences are product status and packaging. DF12D(3.0)-10DP-0.5V(81) is obsolete with unspecified packaging, while DF12NC(3.0)-10DP-0.5V(51) is active with Tape & Reel packaging. The "NC" designation in the substitute indicates the current product variant within the DF12 series.

Q: Will this substitute work in existing designs without modification? A: Yes. All electrical and mechanical parameters are identical. No PCB redesign, schematic changes, or assembly process modifications are necessary.

Q: Are there any compliance differences? A: Both parts are RoHS compliant. The substitute provides ROHS3 compliance and documented REACH compliance status, offering enhanced regulatory documentation.

Q: What is the contact finish specification? A: Both parts feature gold-plated contacts. The substitute specifies contact finish thickness as 8.00µin (0.203µm), providing documented plating specifications.

Q: Is the moisture sensitivity level the same? A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
