Key Parameters

Substitute Part Grouping Explanation

The DF12NB(4.6)-30DP-0.5V(51) qualifies as a parametric equivalent based on the following critical substitution criteria:

Matching Electrical Parameters:

• Identical number of positions (30)
• Identical pitch specification (0.020" / 0.50mm)
• Identical number of rows (2)
• Identical contact finish material and thickness (Gold, 8.00µin)

Matching Mechanical Parameters:

• Identical connector type (Header, Outer Shroud Contacts)
• Identical mounting type (Surface Mount)
• Identical mated stacking height (4.6mm)
• Identical height above board (0.110" / 2.80mm)
• Identical solder retention feature

Compliance Alignment:

• Both RoHS Compliant
• Both MSL 1 (Unlimited)
• Same ECCN and HTSUS classifications

The primary distinction is product status: the substitute part is Active, whereas the original is Obsolete. Packaging differs (Tape & Reel for substitute versus bulk for original), but this does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF12NB(4.6)-30DP-0.5V(51) is the appropriate selection for applications currently specified with DF12B(4.6)-30DP-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 continued manufacturer support.

Both parts carry identical RoHS compliance and MSL ratings, confirming suitability for equivalent environmental and regulatory requirements. The packaging difference (Tape & Reel versus bulk) does not affect functional performance and may provide operational advantages through automated handling compatibility.

Frequently Asked Questions (FAQ)

Q: Are these connectors electrically interchangeable? A: Yes. Both parts share identical electrical specifications including position count (30), pitch (0.50mm), contact finish (gold, 8.00µin thickness), and row configuration (2 rows).

Q: What is the primary reason for substitution? A: The original part DF12B(4.6)-30DP-0.5V(86) is classified as obsolete. The substitute DF12NB(4.6)-30DP-0.5V(51) is an active product with identical specifications, ensuring continued availability and manufacturer support.

Q: Do the mechanical dimensions match? A: Yes. Both connectors have identical mated stacking height (4.6mm), height above board (0.110" / 2.80mm), and mounting type (surface mount). They are mechanically interchangeable.

Q: Does packaging affect compatibility? A: No. The substitute is supplied in Tape & Reel (TR) packaging while the original was bulk packaged. This difference does not affect connector performance or PCB compatibility.

Q: Are compliance certifications identical? A: Yes. Both parts are RoHS Compliant with MSL 1 (Unlimited) rating. ECCN and HTSUS classifications are identical.

Q: Can I use the substitute in existing designs without modification? A: Yes. All electrical, mechanical, and compliance parameters are identical, permitting direct substitution without design changes.
