Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 933011 is based on strict electrical and mechanical parameter alignment:

Critical Matching Parameters:

• Number of Positions: 176
• Pitch: 0.079" (2.00mm)
• Termination Method: Press-Fit
• Connector Type: Receptacle, Female Sockets
• Mounting Configuration: Board Edge, Through Hole, Right Angle

The substitute part 5646442-1 (TE Connectivity AMP Connectors, Z-PACK series) satisfies all critical parameters. This part maintains identical position count, pitch spacing, and press-fit termination architecture, ensuring mechanical and electrical compatibility with existing PCB designs and mating connectors.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5646442-1

The 5646442-1 is the manufacturer-recommended substitute for the obsolete 933011. Selection is based on the following engineering criteria:

1. Functional Equivalence: Identical position count (176), pitch (2.00mm), termination method (press-fit), and mounting configuration ensure direct PCB compatibility without redesign.

2. Product Status: The 5646442-1 is classified as Active, ensuring long-term availability, ongoing manufacturing support, and supply chain continuity.

3. Regulatory Compliance: The substitute part carries RoHS Compliant and REACH Unaffected certifications, meeting current environmental and regulatory requirements. The original 933011 compliance status is not documented.

4. Electrical Specifications: The substitute provides documented electrical ratings (1.5 A, 750Vrms) and operating temperature range (-55°C ~ 125°C), enabling proper system design validation.

5. Quality and Reliability: MSL 1 (Unlimited) moisture sensitivity level indicates robust handling characteristics suitable for standard manufacturing and storage environments.

6. Inventory Availability: 16,229 units of the 5646442-1 are in stock, compared to 876 units of the obsolete 933011, ensuring reliable procurement for current and future production.

Frequently Asked Questions (FAQ)

Q1: Can the 5646442-1 be used as a direct replacement for the 933011 without PCB modification?

A: Yes. Both parts share identical mechanical and electrical interface parameters: 176 positions, 0.079" (2.00mm) pitch, press-fit termination, and board edge right-angle mounting. No PCB redesign is required.

Q2: What is the primary reason for substitution?

A: The 933011 is obsolete and no longer manufactured. The 5646442-1 is the active equivalent from TE Connectivity, ensuring continued availability and manufacturing support.
