Engineering Selection Recommendations
Primary Substitute - Direct Equivalent: MDF7-20P-2.54DSA(96) is the recommended primary substitute. Manufactured by Hirose Electric, this part maintains identical electrical and mechanical specifications to the obsolete MDF7-20P-2.54DSA(01) while offering active product status and RoHS compliance. This substitution requires no design modification.
Secondary Substitutes - Cross-Manufacturer Options:
For applications requiring active product availability with extended environmental specifications, 2-826648-0 (TE Connectivity AMPMODU Mod II) provides enhanced current rating (5A) and expanded operating temperature range (-65°C ~ 105°C) with RoHS compliance. Contact geometry and overall length differ slightly but maintain functional compatibility for standard board-to-board applications.
68004-120HLF (Amphenol ICC BERGSTIK® II) offers RoHS compliance with 5A current rating and gold-plated contacts. Operating temperature range is not specified; verify thermal requirements before selection.
78511-420HLF (Amphenol ICC BERGSTIK® II) provides RoHS compliance, 5A current rating, and extended operating temperature range (-65°C ~ 125°C) with tin contact finish. This part is suitable for applications requiring wider temperature performance.
Alternative Contact Configurations: Mill-Max 342-10-120-00-592000 and 351-10-120-00-004000 feature post-type extended contacts with gold finish and ROHS3 compliance. These parts accommodate different mating interface requirements and are suitable for applications using receptacle connectors designed for post-type headers.
Non-Compliant Options: 54101-T32-20, 68004-220H, and 68024-120 are RoHS non-compliant and should be selected only when legacy system compatibility or specific application constraints mandate their use.
Frequently Asked Questions (FAQ)
Q: Can MDF7-20P-2.54DSA(96) be used as a direct replacement for MDF7-20P-2.54DSA(01)?
A: Yes. Both parts are manufactured by Hirose Electric with identical connector type, position count, pitch, contact configuration, and material specifications. The primary difference is product status: MDF7-20P-2.54DSA(01) is obsolete while MDF7-20P-2.54DSA(96) is active. No design modification is required.
Q: What are the key differences between Hirose MDF7 and TE Connectivity 2-826648-0?
A: Both maintain 20-position, 0.100" pitch, male pin configuration with gold-plated brass contacts and through-hole solder termination. TE Connectivity part offers higher current rating (5A vs 3A) and wider operating temperature range (-65°C ~ 105°C vs -35°C ~ 85°C). Contact length and overall connector height differ slightly. Verify mechanical fit in existing PCB layouts before substitution.
Q: Are Mill-Max post-type headers compatible with MDF7 male pin headers?
A: No. Mill-Max 342 and 351 series feature post-type extended contacts designed to mate with receptacle connectors, not male pin headers. These parts are suitable only for applications using complementary receptacle-type connectors.
Q: Which substitute parts maintain RoHS compliance?
A: RoHS-compliant alternatives include MDF7-20P-2.54DSA(96), 2-826648-0, 342-10-120-00-592000, 351-10-120-00-004000, 68004-120HLF, and 78511-420HLF. Parts 54101-T32-20, 68004-220H, and 68024-120 are RoHS non-compliant.
Q: What is the significance of contact finish differences (gold vs tin)?
A: Gold-plated contacts provide superior corrosion resistance and lower contact resistance, suitable for general-purpose applications. Tin-plated contacts (54101-T32-20, 78511-420HLF) offer cost advantages and are acceptable for non-corrosive environments. Contact finish thickness varies across manufacturers; verify specifications for applications with specific reliability requirements.
Q: Can Amphenol ICC BERGSTIK® II parts replace Hirose MDF7 in all applications?
A: Amphenol ICC parts maintain compatible pitch, position count, and through-hole termination. However, contact material differs (phosphor bronze vs brass), contact length varies, and operating temperature specifications are not provided for some variants. Verify mechanical fit, electrical performance, and environmental requirements before substitution in critical applications.
Q: What packaging options are available for substitute parts?
A: Packaging varies by manufacturer and part number. MDF7-20P-2.54DSA(96) is supplied in bags. TE Connectivity 2-826648-0 is supplied in bulk. Mill-Max parts are supplied in tubes. Amphenol ICC parts are supplied in bags or bulk. Verify packaging requirements for production and inventory management.
