DF11-22DP-2V(50) Equivalent & Substitute Parts

Part Overview

The DF11-22DP-2V(50) is a surface mount rectangular connector header manufactured by Hirose Electric Co Ltd, featuring 22 positions across 2 rows with 0.079" (2.00mm) pitch spacing. This shrouded, board-to-board connector with detent lock fastening and solder termination operates across -30°C to 85°C with a 250V rating and 2A current capacity. The part is classified as obsolete, necessitating identification of active substitute components that maintain electrical and mechanical compatibility for new designs and production continuity.

Engineering Selection Recommendations

All Samtec TMMH-111 series substitutes listed are active production components with ROHS3 compliance, providing supply continuity for the obsolete DF11-22DP-2V(50). The substitutes maintain identical electrical connectivity through matching pitch, position count, and row configuration. Selection among the TMMH-111 variants depends on specific design requirements regarding contact finish specifications and board lock features.

Variants with "-EPC" designation include board lock features for enhanced mechanical retention. Variants with "-EP" designation omit board lock. Contact finish options include:

F-DV: Tin post finish with 3.00µin gold mating finish
G-DV: Gold post finish with 20.0µin gold mating finish
L-DV: Tin post finish with 10.0µin gold mating finish
S-DV: Tin post finish with 30.0µin gold mating finish
T-DV: Tin finish on both mating and post surfaces

The TMMH-111-04-T-DV variants operate to 105°C maximum, while all other variants support -55°C to 125°C operation, exceeding the original part's -30°C to 85°C range. The unshrouded configuration of TMMH-111 substitutes differs from the shrouded 4-wall design of the DF11-22DP-2V(50); design layout verification is required to confirm mechanical fit within existing board space constraints.

Frequently Asked Questions (FAQ)

Q: Are the TMMH-111 series connectors electrically compatible with the DF11-22DP-2V(50)?

A: Yes. All TMMH-111 variants maintain identical pitch (0.079" / 2.00mm), position count (22), row configuration (2 rows), and row spacing (0.079" / 2.00mm). Electrical connectivity is preserved across all substitute options.

Q: What is the primary difference between the DF11-22DP-2V(50) and TMMH-111 substitutes?

A: The main differences are shrouding configuration (DF11 is shrouded 4-wall; TMMH-111 is unshrouded), fastening mechanism (DF11 uses detent lock; TMMH-111 uses push-pull), and insulation material (DF11 uses polyamide; TMMH-111 uses LCP). The TMMH-111 series also features cuttable header design for flexible position configuration.

Q: Do I need to modify my PCB layout to accommodate TMMH-111 substitutes?

A: The unshrouded design of TMMH-111 connectors may require layout verification to confirm mechanical fit. The contact pitch and position spacing remain identical, but the absence of shrouding walls and different fastening mechanism may affect board space requirements and mating interface design.

Q: Which TMMH-111 variant should I select?

A: Selection depends on contact finish requirements and board lock necessity. For applications requiring enhanced mechanical retention, select "-EPC" variants. For standard applications, "-EP" variants are suitable. Contact finish selection (F, G, L, S, or T) should align with mating connector specifications and environmental exposure requirements.

Q: Are all TMMH-111 variants in active production?

A: Yes. All listed TMMH-111-04 variants are active production components with ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring long-term supply availability.

Q: What is the operating temperature range difference?

A: The DF11-22DP-2V(50) operates -30°C to 85°C. TMMH-111 variants with F, G, L, and S designations operate -55°C to 125°C. TMMH-111 variants with T designation operate -55°C to 105°C. All substitutes exceed the original part's temperature range.
