Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF11Z-26DP-2V(21) is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (26)
• Number of rows (2)
• Pitch specification (2.00mm mating pitch, 2.00mm row spacing)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Fastening type (Detent Lock)
• Current rating (2A)
• Voltage rating (250V)
• Operating temperature range (-30°C ~ 85°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance status

The DF11CZ-26DP-2V(27) qualifies as a direct substitute based on complete alignment with all critical electrical and mechanical parameters. Differences in packaging format, insulation color, and product status do not affect functional compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The DF11CZ-26DP-2V(27) is the qualified substitute for the obsolete DF11Z-26DP-2V(21). Selection is based on the following engineering criteria:

Product Status: The DF11CZ-26DP-2V(27) maintains active production status with Hirose Electric Co Ltd, ensuring long-term availability and supply chain continuity compared to the obsolete DF11Z variant.

Electrical Equivalence: Both parts maintain identical electrical specifications including 2A current rating, 250V voltage rating, and operating temperature range of -30°C to 85°C. No circuit redesign is required.

Mechanical Compatibility: Connector geometry, pitch specifications (2.00mm), row configuration (2 rows, 26 positions), and mating interface dimensions are fully equivalent. PCB footprint compatibility is maintained.

Compliance: Both parts are RoHS compliant and carry UL94 V-0 material flammability rating. Moisture sensitivity level (MSL 1) is identical, indicating no special handling requirements.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes. This packaging format is compatible with standard pick-and-place equipment.

Frequently Asked Questions (FAQ)

Q: Can the DF11CZ-26DP-2V(27) be used as a direct replacement for DF11Z-26DP-2V(21) without PCB redesign?

A: Yes. The DF11CZ-26DP-2V(27) maintains identical pitch (2.00mm), position count (26), row configuration (2 rows), and mounting type (surface mount). PCB footprint compatibility is preserved, and no circuit modifications are required.

Q: What is the difference between the DF11Z and DF11C variants?

A: The primary difference is product status and packaging format. The DF11Z-26DP-2V(21) is obsolete and supplied in standard packaging, while the DF11CZ-26DP-2V(27) is in active production and supplied in Tape & Reel format. Electrical and mechanical specifications are identical.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical current rating (2A), voltage rating (250V), operating temperature range (-30°C to 85°C), and contact material (brass with tin finish). Electrical performance is equivalent.

Q: Does the insulation color difference affect functionality?

A: No. The insulation color difference (Natural vs. Beige) is cosmetic only and does not affect electrical or mechanical performance. Both use identical polyamide (PA) nylon material with UL94 V-0 flammability rating.

Q: Is the Tape & Reel packaging compatible with automated assembly?

A: Yes. Tape & Reel (TR) packaging is the standard format for automated pick-and-place assembly equipment. This packaging format is compatible with standard SMD assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the DF11Z-26DP-2V(21) and DF11CZ-26DP-2V(27) are RoHS compliant with identical moisture sensitivity level (MSL 1), indicating unlimited shelf life under standard storage conditions.

Q: What are the mated stacking heights for these connectors?

A: Both parts support identical mated stacking heights of 8.2mm, 8.45mm, and 9.55mm, depending on the mating connector configuration used in the application.
