Engineering Selection Recommendations

The TE Connectivity Aerospace, Defense and Marine 2065657-1 is the direct functional equivalent for the obsolete TE Connectivity Erni 384066. Selection of this substitute is based on the following engineering criteria:

Product Status Alignment: The 384066 is classified as obsolete with no active manufacturing. The 2065657-1 maintains active product status with confirmed inventory availability (1677 Pcs New Original In Stock), ensuring long-term supply chain continuity.

Electrical and Mechanical Equivalence: All critical parameters match exactly: 120-position receptacle configuration, 0.098" (2.50mm) pitch, board edge through-hole right-angle mounting, 0.600A current rating, and 250V voltage rating. Operating temperature range (-65°C to 105°C) and shielded construction are identical.

Compliance Enhancement: The 2065657-1 carries ROHS3 compliance certification and REACH unaffected status, providing improved regulatory alignment compared to the obsolete part. Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) indicates no moisture-related handling restrictions.

Packaging and Availability: The substitute is supplied in tube packaging with confirmed new original inventory status, supporting standard procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can the 2065657-1 be used as a direct replacement for the 384066 in existing designs?

A: Yes. The 2065657-1 matches all specified electrical and mechanical parameters of the 384066, including position count, pitch, mounting configuration, current and voltage ratings, and operating temperature range. No design modifications are required for connector-level substitution.

Q: What is the difference between the TE Connectivity Erni and TE Connectivity Aerospace, Defense and Marine product lines?

A: Both are TE Connectivity divisions. The 384066 was manufactured under the Erni division and is now obsolete. The 2065657-1 is manufactured under the Aerospace, Defense and Marine division and maintains active production status. Both parts meet identical electrical and mechanical specifications for this connector category.

Q: Does the 2065657-1 have any additional certifications or compliance advantages?

A: The 2065657-1 carries ROHS3 compliance and REACH unaffected status. The original 384066 specification does not document these certifications. The MSL rating of 1 (Unlimited) on the substitute indicates no moisture sensitivity restrictions during storage or handling.

Q: Are there any packaging differences between the two parts?

A: The 384066 packaging is not specified in available documentation. The 2065657-1 is supplied in tube packaging, which is standard for high-pin-count connectors and supports automated assembly processes.

Q: What is the contact layout configuration for both parts?

A: Both the 384066 and 2065657-1 use an identical contact layout of 80 single signal contacts and 40 ground contacts across the 120-position array, maintaining signal integrity and grounding performance.

Q: Is the 2065657-1 available in the same quantity as the 384066?

A: The 2065657-1 has higher current inventory availability (1677 Pcs New Original In Stock) compared to the 384066 (879 Pcs), providing improved procurement flexibility for new designs and production requirements.
