Engineering Selection Recommendations

The DF1EG-8P-2.5DSA(35) is the appropriate substitute for the obsolete DF1EE-8P-2.5DSA(35). Both connectors share identical electrical and mechanical specifications across all critical parameters including pitch, position count, contact configuration, current rating, and operating temperature range.

The substitute part offers the advantage of active product status, ensuring ongoing availability and manufacturing support. Both parts maintain equivalent RoHS compliance and UL94 V-0 flammability certification. The DF1EG variant includes REACH Unaffected status documentation, providing additional regulatory clarity for international applications.

Minor dimensional differences exist in contact post length (0.142" versus 0.118") and insulation height (0.425" versus 0.642"), which do not affect functional compatibility in standard board-to-cable applications. Mated stacking heights remain identical across both variants.

Frequently Asked Questions (FAQ)

Q: Can the DF1EG-8P-2.5DSA(35) directly replace the DF1EE-8P-2.5DSA(35) in existing designs?

A: Yes. Both connectors maintain identical pitch (2.50mm), position count (8), contact type (male pin), mounting method (through-hole solder), and electrical ratings (3A, -35°C ~ 85°C). The connectors are mechanically and electrically compatible for board-to-cable/wire applications.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active) and minor dimensional variations. The DF1EG features a longer insulation height (16.30mm versus 10.80mm) and shorter contact post length (3.00mm versus 3.60mm). These dimensional changes do not affect standard mating or termination procedures.

Q: Are there any compliance or certification differences?

A: Both parts maintain UL94 V-0 flammability rating and RoHS compliance. The DF1EG includes REACH Unaffected status documentation. Both carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the packaging difference?

A: The DF1EE-8P-2.5DSA(35) is listed with unspecified packaging, while the DF1EG-8P-2.5DSA(35) is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are the mated stacking heights the same?

A: Yes. Both connectors support identical mated stacking heights of 14.3mm, 15.8mm, and 19.8mm, ensuring compatibility with existing connector stacking configurations.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
