TE Connectivity Erni 933070 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 933070 is an 88-position receptacle connector with 2mm press-fit termination. This component is classified as Obsolete and is no longer in active production. Due to its obsolete status, identification of functionally equivalent active alternatives is necessary to support ongoing system maintenance, repair, and new design implementations. The substitute part maintains the same electrical and mechanical interface specifications, enabling direct functional replacement in applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 933070 is based on the following critical parameters that must remain constant:

• Number of Positions: 88 positions (electrical interface requirement)
• Pitch Specification: 2.00mm (0.079") center-to-center spacing (mechanical interface requirement)
• Termination Method: Press-Fit (board integration method)
• Connector Type: Receptacle with Female Sockets (functional role in assembly)

The substitute part 5646492-1 (TE Connectivity AMP Connectors) satisfies all four critical parameters. This part is classified as Active in production status, ensuring long-term availability and supply chain continuity. The substitute maintains identical electrical and mechanical interface specifications, permitting direct functional replacement without circuit design modification.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5646492-1

The part 5646492-1 is the manufacturer-recommended substitute for the obsolete TE Connectivity Erni 933070. Selection of this substitute is based on the following engineering criteria:

1. Functional Equivalence: All critical electrical and mechanical parameters (88 positions, 2.00mm pitch, press-fit termination, receptacle configuration) are identical to the original part.

2. Active Production Status: The substitute is classified as Active, ensuring availability for current procurement and future supply chain requirements.

3. Regulatory Compliance: The substitute carries RoHS Compliant certification and EAR99 ECCN classification, meeting current environmental and export control standards.

4. Moisture Sensitivity: MSL rating of 1 (Unlimited) indicates no special moisture handling requirements during storage or assembly.

5. Inventory Availability: 1036 pieces of new original stock are available, supporting both immediate replacement needs and production requirements.

The substitute part is packaged in Box format and belongs to the Z-PACK series. No design modifications, circuit alterations, or board layout changes are required for implementation of this substitute.

Frequently Asked Questions (FAQ)

Q: Can the 5646492-1 be used as a direct replacement for the 933070 in existing assemblies?

A: Yes. The substitute part maintains identical specifications for the four critical parameters: 88 positions, 2.00mm pitch, press-fit termination, and receptacle configuration. Direct functional replacement is supported without circuit design modification.

Q: What is the difference between the original part and the substitute?

A: The original TE Connectivity Erni 933070 is obsolete and no longer manufactured. The substitute TE Connectivity AMP 5646492-1 is an active production part from the same manufacturer (TE Connectivity) that meets all electrical and mechanical interface requirements. The substitute provides additional documented specifications including current rating (1.5 A), voltage rating (750Vrms), operating temperature range (-55°C ~ 125°C), and RoHS compliance.

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

A: The original part packaging is listed as "-" (not specified). The substitute is packaged in Box format. This difference affects only logistics and storage; the connector itself maintains identical form factor and interface specifications.

Q: What certifications does the substitute carry?

A: The substitute part 5646492-1 carries RoHS Compliant certification and is classified as EAR99 for export control purposes. Moisture Sensitivity Level is rated as 1 (Unlimited), indicating no special moisture handling protocols are required.

Q: Is the substitute suitable for new design implementations?

A: Yes. The substitute is an active production part with full technical documentation and regulatory compliance. It is suitable for both replacement of obsolete components and incorporation into new designs requiring 88-position, 2mm pitch press-fit receptacle connectors.

Q: What is the series designation of the substitute part?

A: The substitute part belongs to the Z-PACK series from TE Connectivity AMP Connectors.
