Engineering Selection Recommendations

Primary Substitute (Hirose Series): MDF7-9P-2.54DSA(96) is the direct equivalent from Hirose Electric with active product status. This part maintains identical electrical and mechanical specifications to the obsolete MDF7-9P-2.54DSA(01), including gold contact finish, PBT insulation, and RoHS compliance. This is the preferred substitution path for designs currently using the original part.

3M 929705 Series (Gold-Plated Variants): The 929705-01-09-EU, 929705-01-09-I, 929705-06-09-EU, 929705-06-09-I, and 929705-09-09-EU parts offer gold-plated mating contacts matching the original specification. All variants are RoHS compliant and active products. These parts feature extended operating temperature range (-40°C to 105°C) compared to the original (-35°C to 85°C). Contact post length varies across variants, affecting overall connector height.

3M 929700 Series (Tin/Tin-Lead Variants): The 929700-01-09-RK provides RoHS compliance with tin contact finish and extended temperature range. The 929700-01-09 and 929700-06-09 variants are non-compliant with RoHS regulations and use tin-lead contact finish. These parts carry a reduced current rating of 2.5A compared to the original 3A specification.

Molex 0022303093: This part maintains 9-position, 2.54mm pitch configuration with through-hole solder termination. The part features kinked pin termination and polyamide insulation with glass reinforcement. ROHS3 compliance is confirmed. Operating temperature and current rating specifications are not provided in the data.

Frequently Asked Questions (FAQ)

Q: Can MDF7-9P-2.54DSA(96) be used as a direct replacement for MDF7-9P-2.54DSA(01)?

A: Yes. MDF7-9P-2.54DSA(96) is functionally equivalent to the obsolete MDF7-9P-2.54DSA(01). Both parts share identical pitch (2.54mm), position count (9), contact type (male pin), mounting method (through-hole), termination (solder), contact finish (gold), insulation material (PBT), and flammability rating (UL94 V-0). The primary difference is product status: the (96) variant is active while the (01) is obsolete.

Q: What is the difference between 929705-01-09-EU and 929705-01-09-I variants?

A: Both parts are functionally equivalent 3M 929705 series connectors with 9 positions, 2.54mm pitch, gold contact finish, and RoHS compliance. The primary difference is insulation material: the -EU variant uses polycyclohexylenedimethylene terephthalate (PCT), while the -I variant uses polybutylene terephthalate (PBT) with polyester and glass filling. Contact post length is identical at 0.110" (2.79mm) for both variants.

Q: Why do 3M 929700 series parts have a lower current rating (2.5A) than the original (3A)?

A: The current rating difference reflects the design specifications of the 3M 929700 series connectors. While both connector families maintain the same pitch, position count, and mounting configuration, the 929700 series is rated for 2.5A maximum current. Applications requiring the full 3A rating should select parts with equivalent current specifications.

Q: Are there differences in contact post length among the substitute parts?

A: Yes. Contact post length varies across substitute options. The original MDF7-9P-2.54DSA(01) specifies 0.118" (3.00mm) post length. The 3M 929705 series offers variants with 0.110" (2.79mm) post length (929705-01-09 variants) and 0.145" (3.68mm) post length (929705-09-09-EU). The 3M 929700 series specifies 0.110" (2.79mm) for standard variants and 0.710" (18.03mm) for extended post variants (929700-06-09). Post length affects PCB stack-up and mating depth considerations.

Q: Which substitute parts maintain RoHS compliance?

A: RoHS-compliant substitutes include MDF7-9P-2.54DSA(96) (Hirose), 0022303093 (Molex, ROHS3), 929700-01-09-RK (3M), and all 929705 series variants (929705-01-09-EU, 929705-01-09-I, 929705-06-09-EU, 929705-06-09-I, 929705-09-09-EU). The 929700-01-09 and 929700-06-09 variants are RoHS non-compliant.

Q: What is the temperature operating range for each substitute family?

A: The original MDF7-9P-2.54DSA(01) operates from -35°C to 85°C. The Hirose MDF7-9P-2.54DSA(96) maintains this range. All 3M 929700 and 929705 series parts extend the operating range to -40°C to 105°C. The Molex 0022303093 does not specify operating temperature in the provided data.
