Direct Hirose Substitute: The DF11GZ-22DP-2V(20) is a direct manufacturer equivalent from Hirose Electric Co Ltd, differing only in product status (Last Time Buy vs. Obsolete) and RoHS compliance status. This part maintains identical electrical and mechanical specifications.

Cross-Manufacturer Alternatives: The Samtec TMMH-111 series provides functional alternatives with the same pitch, position count, and row configuration. These parts are cuttable headers with unshrouded design and push-pull fastening, representing a design variation from the original shrouded detent-lock architecture. The TMMH series offers multiple contact finish options (tin, gold variants) and extended operating temperature ranges (-55°C ~ 125°C), with active product status and RoHS3 compliance.

Engineering Selection Recommendations

For Direct Replacement (Preferred): The DF11GZ-22DP-2V(20) is the recommended substitute for the obsolete DF11G-22DP-2V(20). This part maintains identical mechanical and electrical specifications while offering improved product status (Last Time Buy) and RoHS compliance. No design modifications are required for PCB layout or mating connector specifications.

For New Designs or Long-Term Availability: The Samtec TMMH-111 series provides active product status with extended availability. These parts require design consideration due to architectural differences: unshrouded construction, push-pull fastening instead of detent lock, and cuttable header design. The TMMH series offers superior operating temperature range (-55°C ~ 125°C) and RoHS3 compliance. Contact finish options (tin or gold variants) accommodate different application requirements.

Compliance Considerations: Applications requiring RoHS compliance should utilize DF11GZ-22DP-2V(20) or any TMMH-111 variant. The original DF11G-22DP-2V(20) is RoHS non-compliant and unsuitable for new designs subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can the DF11GZ-22DP-2V(20) be used as a direct drop-in replacement for the DF11G-22DP-2V(20)?

A: Yes. The DF11GZ-22DP-2V(20) is electrically and mechanically identical to the DF11G-22DP-2V(20). Both parts share the same pitch (0.079"), position count (22), row configuration (2 rows), shrouding (4-wall), and fastening mechanism (detent lock). No PCB modifications are required.

Q: What are the key differences between Hirose DF11 and Samtec TMMH-111 headers?

A: The primary differences are: (1) Shrouding—DF11 is shrouded with 4 walls; TMMH-111 is unshrouded; (2) Fastening—DF11 uses detent lock; TMMH-111 uses push-pull; (3) Design—TMMH-111 is cuttable; DF11 is not; (4) Contact material—DF11 uses brass; TMMH-111 uses phosphor bronze; (5) Operating temperature—TMMH-111 supports -55°C ~ 125°C versus DF11's -30°C ~ 85°C. These differences require PCB layout and mating connector evaluation.

Q: Are all TMMH-111 variants functionally equivalent for the 22-position, 2-row configuration?

A: All listed TMMH-111 variants (F, G, L, S, T designations) maintain identical pitch, position count, row spacing, and mounting specifications. Variants differ in contact finish composition and thickness. Selection depends on application requirements for contact plating durability and corrosion resistance.

Q: What is the significance of the "cuttable" feature on TMMH-111 headers?

A: The cuttable design allows the header strip to be segmented to custom lengths during assembly. This provides flexibility for applications requiring non-standard position counts. The DF11G-22DP-2V(20) and DF11GZ-22DP-2V(20) are fixed 22-position assemblies without this capability.

Q: Does the unshrouded design of TMMH-111 affect electrical performance compared to the shrouded DF11?

A: Electrical performance (current rating, voltage rating, contact resistance) remains equivalent. The unshrouded design reduces physical envelope and cost but provides less mechanical protection during handling and assembly. Application environment and handling procedures should be evaluated when transitioning from shrouded to unshrouded designs.

Q: Which substitute part offers the best long-term availability?

A: The Samtec TMMH-111 series offers active product status with highest availability assurance. The DF11GZ-22DP-2V(20) is listed as Last Time Buy, indicating limited future availability. For new designs requiring extended production timelines, TMMH-111 variants are preferred.
