Key Parameters

Substitute Part Grouping Explanation

The DF12NB(3.0)-36DP-0.5V(51) qualifies as a direct substitute based on the following critical parameters:

• Connector Configuration: Both parts maintain 36 positions in a 2-row arrangement with 0.50mm pitch
• Electrical Specifications: Identical contact finish (gold plating at 8.00µin thickness) and solder retention features
• Mechanical Compatibility: Matching mated stacking height (3mm) and height above board (2.30mm) ensure PCB layout compatibility
• Compliance: Both parts are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity)
• Series Continuity: Both belong to the DF12 series from Hirose Electric Co Ltd

The primary distinction is the base product designation (DF12B versus DF12N) and packaging format. The substitute part is available in active product status with Tape & Reel packaging, providing superior supply chain availability compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

The DF12NB(3.0)-36DP-0.5V(51) is the appropriate selection for applications currently specified with DF12B(3.0)-36DP-0.5V(86). The substitute part maintains full electrical and mechanical compatibility across all critical parameters. The transition from obsolete to active product status ensures long-term supply chain viability and manufacturing support. Both parts satisfy identical RoHS compliance and MSL requirements, eliminating any regulatory or environmental concerns in the substitution. The Tape & Reel packaging of the substitute part aligns with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the DF12B and DF12N variants electrically interchangeable?

A: Yes. Both variants maintain identical contact finish specifications (gold plating at 8.00µin thickness), pitch (0.50mm), and connector configuration (36 positions, 2 rows). The electrical performance is equivalent for all signal integrity and power delivery applications.

Q: Will the substitute part fit existing PCB layouts designed for the original part?

A: Yes. The substitute maintains identical mechanical dimensions: 3mm mated stacking height and 0.091" (2.30mm) height above board. PCB footprints and mating connector specifications require no modification.

Q: What is the significance of the packaging change from unspecified to Tape & Reel?

A: Tape & Reel packaging is the standard format for surface mount components in automated assembly environments. This packaging format improves handling efficiency and reduces component damage during manufacturing processes.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are RoHS compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 1, indicating unlimited shelf life under standard storage conditions. ECCN and HTSUS classifications remain unchanged.

Q: Why is the original part classified as obsolete?

A: Product obsolescence typically results from manufacturer lifecycle decisions. The availability of the functionally equivalent DF12NB variant with active product status provides a direct path for design continuity without performance compromise.
