Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF11Z-16DP-2V(21) is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 16 positions in 2 rows
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Surface mount with solder termination
• Mechanical Interface: Shrouded 4-wall design with detent lock fastening
• Electrical Performance: 2A current rating and 250V voltage rating
• Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1

The DF11CZ-16DP-2V(27) qualifies as a manufacturer-recommended substitute by maintaining identical specifications across all critical parameters while offering active product status and improved packaging options.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can DF11CZ-16DP-2V(27) be used as a direct replacement for DF11Z-16DP-2V(21)?

A: Yes. Both components share identical specifications for connector type, position count, pitch, mounting method, electrical ratings, and operating temperature range. The DF11CZ-16DP-2V(27) is the manufacturer-recommended substitute and requires no design changes.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging. The DF11Z-16DP-2V(21) is obsolete and supplied in standard packaging, while the DF11CZ-16DP-2V(27) is active production and supplied in Tape & Reel format. The "Z" designation in DF11Z indicates the obsolete variant, while "C" in DF11C indicates the current production series.

Q: Are there any compatibility concerns with PCB layouts?

A: No. Both parts maintain identical mating pitch (0.079" / 2.00mm), row spacing, insulation height (0.283" / 7.19mm), and mated stacking heights (8.2mm, 8.45mm, 9.55mm). Existing PCB footprints and connector receptacles are fully compatible.

Q: Does the Tape & Reel packaging affect electrical performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tape & Reel packaging is a manufacturing and logistics consideration that improves assembly efficiency and cost-effectiveness for high-volume production.

Q: Are both parts RoHS compliant?

A: Yes. The DF11Z-16DP-2V(21) is RoHS Compliant, and the DF11CZ-16DP-2V(27) is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the current rating and voltage specification?

A: Both components are rated for 2A current at 250V, making them suitable for standard low-voltage signal and power distribution applications within these electrical limits.
