Key Parameters

Substitute Part Grouping Explanation

The DF11CZ-4DP-2V(27) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Connector Type & Configuration: Both parts are rectangular connector headers with identical 4-position, 2-row layout
• Pitch Specification: Both maintain 0.079" (2.00mm) mating pitch and row spacing
• Manufacturer Consistency: Both are manufactured by Hirose Electric Co Ltd within the DF11 series family
• Electrical Ratings: Both support 2A current rating and 250V voltage rating
• Mounting Interface: Both feature shrouded 4-wall design with detent lock fastening
• Contact Configuration: Both use male pin contacts with tin finish on brass material

The primary distinction is that DF11CZ-4DP-2V(27) is an active production part with surface mount termination, whereas the original DF11Z-4DP-2V(21) is obsolete. The substitution maintains all critical electrical and mechanical parameters required for board-to-board or cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

The DF11CZ-4DP-2V(27) is the appropriate substitute for the obsolete DF11Z-4DP-2V(21) based on the following engineering criteria:

Product Status & Availability: The original part is obsolete with no active production. The substitute is an active production component with confirmed inventory availability (56,817 pcs in stock), ensuring reliable sourcing for current and future applications.

Compliance & Certifications: The substitute part maintains UL94 V-0 flammability rating and achieves ROHS3 compliance, meeting modern regulatory requirements. The MSL rating of 1 (Unlimited) provides superior moisture handling compared to the original specification.

Electrical & Mechanical Compatibility: All critical parameters—pitch, contact configuration, current/voltage ratings, operating temperature range, and fastening mechanism—are identical between the original and substitute parts. This ensures direct functional equivalence in board-to-board or cable connection applications.

Manufacturing Continuity: Both parts are from the same manufacturer (Hirose Electric Co Ltd) and belong to the DF11 series family, confirming design lineage and compatibility within the connector ecosystem.

Frequently Asked Questions (FAQ)

Q: Can DF11CZ-4DP-2V(27) be used as a direct replacement for DF11Z-4DP-2V(21)?

A: Yes. Both connectors share identical pitch (2.00mm), position count (4), row configuration (2), contact type (male pin), electrical ratings (2A/250V), and fastening mechanism (detent lock). The substitute is functionally equivalent for all board-to-board and cable connection applications.

Q: What is the primary difference between these two parts?

A: The DF11CZ-4DP-2V(27) is an active production part with surface mount termination and modern compliance certifications (ROHS3), whereas the DF11Z-4DP-2V(21) is obsolete. The substitute also features improved moisture sensitivity rating (MSL 1 vs. Not Applicable).

Q: Are there any packaging or mounting differences?

A: The substitute part is supplied in Cut Tape (CT) packaging for automated assembly. Both parts use surface mount termination with solder retention features and identical shrouded 4-wall design. No design modifications are required for PCB integration.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The DF11CZ-4DP-2V(27) is ROHS3 compliant and maintains UL94 V-0 flammability rating, meeting current environmental and safety standards. The original part specification does not indicate these certifications.

Q: What are the mated stacking heights for the substitute part?

A: The DF11CZ-4DP-2V(27) provides three mated stacking height options: 8.2mm, 8.45mm, and 9.55mm, allowing flexibility in system design and component integration.
