Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters: pitch (0.079" / 2.00mm), number of positions (22), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (surface mount), termination method (solder), contact type (male pin), and electrical ratings (2A current, 250V voltage). All substitute parts must maintain these core specifications to ensure mechanical and electrical compatibility with existing PCB designs and mating connectors.

The substitute parts are grouped into two categories:

Category 1: Hirose DF11 Series (Direct Manufacturer Alternative) DF11C-22DP-2V(57) maintains identical electrical and mechanical specifications to the main part, with the primary difference being packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy). This part is the direct manufacturer-recommended substitute.

Category 2: Samtec TMMH Series (Cross-Manufacturer Alternatives) The TMMH-111 series parts share core mating parameters (pitch, position count, row configuration, surface mount termination) but introduce design variations in shrouding (unshrouded versus shrouded), contact shape (square versus circular), contact material (phosphor bronze versus brass), insulation material (liquid crystal polymer versus polyamide), fastening mechanism (push-pull versus detent lock), and operating temperature range (-55°C ~ 125°C versus -30°C ~ 85°C). These parts are functionally compatible for applications where the design variations do not conflict with existing mechanical constraints or performance requirements.

Engineering Selection Recommendations

Primary Recommendation: DF11C-22DP-2V(57)

The DF11C-22DP-2V(57) is the manufacturer-recommended direct substitute for the DF11G-22DP-2V(50). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications, including pitch, position count, row configuration, shrouding design, contact material, and operating temperature range. The DF11C variant is in Active product status with higher inventory availability (1458 units) compared to the Last Time Buy DF11G variant (750 units). The primary distinction is packaging format: DF11C-22DP-2V(57) is supplied in Tape & Reel format, which is standard for high-volume production environments. This part requires no design modifications and provides seamless compatibility with existing PCB layouts and mating connectors.

Secondary Recommendations: Samtec TMMH-111 Series

The Samtec TMMH-111 series parts (TMMH-111-04-F-DV-EP, TMMH-111-04-F-DV-EPC, TMMH-111-04-G-DV-EP, TMMH-111-04-G-DV-EPC, TMMH-111-04-L-DV-EP, TMMH-111-04-L-DV-EPC, TMMH-111-04-S-DV-EP, TMMH-111-04-S-DV-EPC, TMMH-111-04-T-DV-EP) are cross-manufacturer alternatives suitable for applications where design flexibility permits accommodation of the following differences:

Samtec TMMH parts feature unshrouded design versus the shrouded 4-wall configuration of the DF11G. The TMMH series uses square contact geometry and phosphor bronze contact material instead of circular brass contacts. Insulation height is significantly reduced (0.079" versus 0.283"), and insulation material is liquid crystal polymer (LCP) instead of polyamide nylon. Fastening mechanism is push-pull instead of detent lock. Operating temperature range extends to -55°C ~ 125°C (or -55°C ~ 105°C for the tin-finish variant), providing broader thermal performance than the DF11G specification of -30°C ~ 85°C.

All Samtec TMMH variants maintain the critical mating parameters: 0.079" (2.00mm) pitch, 22 positions, 2 rows, 0.079" (2.00mm) row spacing, surface mount termination, and male pin contact type. All variants carry Active product status and ROHS3 compliance. Selection among TMMH variants depends on contact finish requirements: variants with suffix F, L, or S provide gold mating finish with varying thickness (3.00µin, 10.0µin, or 30.0µin respectively), while variant T provides tin mating finish. Variants with suffix EPC include board lock feature in addition to end shrouds and mating guide.

Frequently Asked Questions (FAQ)

Q: Can DF11C-22DP-2V(57) be used as a direct replacement for DF11G-22DP-2V(50) without PCB redesign?

A: Yes. Both parts share identical pitch (0.079" / 2.00mm), position count (22), row configuration (2 rows), row spacing (0.079" / 2.00mm), shrouding design (shrouded 4-wall), contact type (male pin), and electrical ratings (2A, 250V). The only difference is packaging format (Tape & Reel versus Tube). No PCB layout modifications are required.

Q: What are the key mechanical differences between Hirose DF11 and Samtec TMMH series?

A: The primary mechanical differences are: (1) Shrouding—DF11 is shrouded 4-wall, TMMH is unshrouded; (2) Contact shape—DF11 uses circular contacts, TMMH uses square contacts; (3) Insulation height—DF11 is 0.283" (7.19mm), TMMH is 0.079" (2.00mm); (4) Fastening—DF11 uses detent lock, TMMH uses push-pull; (5) Insulation material—DF11 is polyamide nylon, TMMH is liquid crystal polymer (LCP). Mating pitch and position count remain identical.

Q: Are Samtec TMMH parts electrically compatible with DF11G-22DP-2V(50)?

A: Yes, for the specified electrical ratings. Both part families support 2A current and 250V voltage. However, Samtec TMMH parts do not specify current or voltage ratings in the provided data. Samtec TMMH parts offer extended operating temperature range (-55°C ~ 125°C or -55°C ~ 105°C) compared to DF11G (-30°C ~ 85°C), providing superior thermal performance in demanding environments.

Q: What is the significance of the TMMH variant suffixes (F, G, L, S, T)?

A: The suffixes indicate contact finish specifications. Suffix F, L, and S denote gold mating finish with different thickness specifications: F = 3.00µin (0.076µm), L = 10.0µin (0.25µm), S = 30.0µin (0.76µm). Suffix T denotes tin mating finish. Selection depends on application requirements for contact durability and corrosion resistance. Higher gold thickness (S variant) provides enhanced wear resistance for high-cycle mating applications.

Q: What does the EPC suffix indicate on Samtec TMMH parts?

A: The EPC suffix indicates the inclusion of board lock feature in addition to end shrouds and mating guide. Parts without EPC suffix (designated EP) include only end shrouds and mating guide. Board lock provides additional mechanical retention during mating operations.

Q: Are all substitute parts RoHS compliant?

A: Yes. DF11C-22DP-2V(57) is RoHS Compliant. All Samtec TMMH variants are ROHS3 Compliant. Both compliance levels meet current environmental regulations for electronic components.

Q: What is the inventory status of substitute parts?

A: DF11C-22DP-2V(57) has 1458 units in stock. Samtec TMMH variants range from 711 to 1165 units in stock, providing adequate supply for production requirements. The original DF11G-22DP-2V(50) has 750 units available but carries Last Time Buy status, indicating no future production.
