Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF11Z-12DP-2V(21) is determined by strict equivalence across the following critical parameters:

• Connector type (Header), contact type (Male Pin), and contact shape (Circular)
• Position count (12) and row configuration (2 rows)
• Pitch specifications: mating pitch 0.079" (2.00mm) and row spacing 0.079" (2.00mm)
• Mounting method (Surface Mount) and shrouding design (Shrouded - 4 Wall)
• Termination method (Solder) and fastening mechanism (Detent Lock)
• Electrical ratings: 2A current and 250V voltage
• Operating temperature range (-30°C ~ 85°C)
• Material compliance: UL94 V-0 flammability rating and RoHS compliance

The DF11CZ-12DP-2V(27) meets all these critical parameters and is classified as a manufacturer-recommended substitute. The primary distinction is product status: the substitute is active production, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The DF11CZ-12DP-2V(27) is the manufacturer-recommended substitute for the obsolete DF11Z-12DP-2V(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters: 12-position, 2-row configuration at 2.00mm pitch, surface mount solder termination with detent lock fastening, 2A/250V ratings, and -30°C to 85°C operating temperature range.

The substitute part is in active production status with significantly higher inventory availability (7049 pcs vs. 813 pcs). Both parts meet UL94 V-0 flammability requirements and RoHS compliance standards. The substitute offers improved supply chain continuity and manufacturing support.

Packaging differs: the original part has unspecified packaging, while the substitute is supplied in Tape & Reel format, which is standard for automated assembly processes. Insulation color varies (Natural vs. Beige), and the substitute includes Pick and Place features in addition to Solder Retention, reflecting modern manufacturing optimization.

Frequently Asked Questions (FAQ)

Q: Are the DF11Z-12DP-2V(21) and DF11CZ-12DP-2V(27) mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (2.00mm), row spacing (2.00mm), position count (12 in 2 rows), insulation height (7.19mm), and mated stacking heights (8.2mm, 8.45mm, 9.55mm). They are mechanically interchangeable in board-to-board applications.

Q: What are the electrical compatibility requirements?

A: Both parts are rated for 2A at 250V with identical operating temperature ranges (-30°C to 85°C). Electrical compatibility is maintained across all specified parameters.

Q: Does the packaging difference affect component selection?

A: The substitute is supplied in Tape & Reel (TR) packaging, which is optimized for automated pick-and-place assembly. The original part packaging is unspecified. For manual assembly or low-volume applications, confirm packaging availability with your supplier.

Q: Are there compliance differences between the two parts?

A: Both parts are UL94 V-0 rated and RoHS compliant. The substitute carries ROHS3 compliance designation, indicating alignment with current regulatory standards. Both have MSL 1 (Unlimited) moisture sensitivity and EAR99 export classification.

Q: What is the significance of the insulation color difference?

A: Insulation color (Natural vs. Beige) is a cosmetic distinction and does not affect electrical or mechanical performance. Selection should be based on application requirements or assembly documentation specifications.

Q: Why is the original part classified as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of production. The DF11CZ-12DP-2V(27) represents the active production equivalent, ensuring long-term supply chain availability and manufacturing support.
