Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF12B-50DS-0.5V(86) are identified based on strict electrical and mechanical parameter matching within the DF12 series. The following parameters determine substitution eligibility:

• Connector Type: Receptacle, Center Strip Contacts
• Number of Positions: 50
• Pitch: 0.020" (0.50mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 8.00µin (0.203µm)
• Mated Stacking Heights: 4.6mm, 4mm, 5mm
• Height Above Board: 0.106" (2.70mm)
• Features: Solder Retention

The identified substitutes—DF12NB-50DS-0.5V(51) and DF12NC-50DS-0.5V(51)—maintain all critical electrical and mechanical parameters. Both substitutes are Active products within the DF12 series, providing improved supply availability compared to the Obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Both DF12NB-50DS-0.5V(51) and DF12NC-50DS-0.5V(51) are direct functional equivalents to the DF12B-50DS-0.5V(86). Selection between substitutes should be based on the following factors:

Product Status: The DF12B-50DS-0.5V(86) is Obsolete. Both substitute parts carry Active status, ensuring long-term availability and continued manufacturing support.

Compliance: The main part meets RoHS Compliance. Both substitutes exceed this requirement with ROHS3 Compliance certification. Both substitutes also carry REACH Unaffected status, providing additional regulatory assurance.

Packaging Consideration: The original part is supplied in bulk packaging. Both substitutes are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and provides improved handling and traceability.

Inventory Availability: While the original part shows higher stock levels (43350 Pcs), both substitutes maintain active inventory (DF12NB: 3889 Pcs; DF12NC: 3039 Pcs), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Are DF12NB-50DS-0.5V(51) and DF12NC-50DS-0.5V(51) electrically and mechanically interchangeable with DF12B-50DS-0.5V(86)?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications including connector type, position count, pitch, row configuration, mounting type, contact finish, and stacking heights. All three parts are within the DF12 series and share the same functional interface.

Q: What is the difference between the two substitute parts?

A: DF12NB-50DS-0.5V(51) and DF12NC-50DS-0.5V(51) are both Active products with identical electrical and mechanical parameters. The primary difference is inventory availability (DF12NB: 3889 Pcs; DF12NC: 3039 Pcs). Selection may be based on procurement lead time and supply chain requirements.

Q: Why is the original part marked as Obsolete?

A: The DF12B-50DS-0.5V(86) is classified as Obsolete, indicating it is no longer in active production. The substitute parts represent the current Active alternatives within the DF12 series that maintain full functional compatibility.

Q: Does the change from bulk packaging to Tape & Reel affect compatibility?

A: No. Packaging format does not affect electrical or mechanical compatibility. Tape & Reel packaging is standard for surface mount components and provides improved handling, storage, and automated assembly integration compared to bulk packaging.

Q: Are there any compliance differences between the main part and substitutes?

A: The main part meets RoHS Compliance. Both substitutes meet the more stringent ROHS3 Compliance standard and carry REACH Unaffected certification, providing enhanced regulatory compliance for new designs and applications.

Q: Can I use these substitutes in existing designs without PCB modification?

A: Yes. All three parts share identical mounting type (Surface Mount), height above board (0.106" / 2.70mm), and mated stacking heights (4.6mm, 4mm, 5mm). No PCB layout or assembly process changes are required.
