TE Connectivity Erni 923131 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 923131 is a 154-position backplane connector header with male pins, featuring a 2.00mm pitch and press-fit termination. This connector is designed for through-hole mounting applications and is classified as obsolete. The part operates across a temperature range of -55°C to 125°C and includes shielding with gold-plated contacts. Due to its obsolete product status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 923131 is determined by strict alignment of the following critical parameters:

Position and Pitch Configuration: The substitute part must maintain the identical 154-position count (110 + 44 Ground) with a 2.00mm pitch and 5 + 2 row configuration to ensure mechanical and electrical compatibility with existing PCB layouts.

Connector Type and Termination: Both the main part and substitute must be header connectors with male pins and press-fit termination to maintain compatibility with mating receptacles and assembly processes.

Mounting and Contact Specifications: Through-hole mounting type and gold contact finish are required to preserve electrical performance and solderability characteristics.

Environmental and Compliance Requirements: Operating temperature range of -55°C to 125°C and RoHS compliance status must be maintained to ensure regulatory and operational compatibility.

The TE Connectivity AMP Connectors 5352128-1 meets all these substitution criteria and is classified as an active product, providing a direct functional equivalent to the obsolete 923131.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5352128-1 is the designated substitute for the obsolete TE Connectivity Erni 923131. This substitution is supported by complete parameter alignment across all critical electrical and mechanical specifications.

Product Status Consideration: The 923131 is classified as obsolete, while the 5352128-1 maintains active product status. This transition ensures long-term component availability and continued manufacturer support.

Compliance Alignment: Both parts maintain RoHS compliance and MSL Level 1 rating, ensuring regulatory compatibility and eliminating moisture sensitivity constraints during storage and handling.

Electrical and Mechanical Compatibility: Identical position count, pitch, row configuration, mounting type, and termination method guarantee direct functional equivalence. The gold contact finish and operating temperature range are preserved across both parts.

Series Transition: The substitution represents a transition from the ERMET series to the Z-PACK series within the TE Connectivity product portfolio. The Z-PACK series designation indicates an active, supported product line with enhanced availability.

Frequently Asked Questions (FAQ)

Q: Can the 5352128-1 be used as a direct replacement for the 923131 in existing designs?

A: Yes. The 5352128-1 maintains identical electrical and mechanical specifications, including position count, pitch, row configuration, mounting type, and termination method. No design modifications are required for substitution.

Q: What is the primary reason for substituting the 923131?

A: The 923131 is classified as obsolete. The 5352128-1 is an active product that provides equivalent functionality with assured long-term availability and manufacturer support.

Q: Are there packaging differences between these parts?

A: Yes. The 923131 is supplied in Tray packaging, while the 5352128-1 is supplied in Tube packaging. Packaging format does not affect electrical or mechanical compatibility; it only impacts storage and handling procedures.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and carry MSL Level 1 rating. The 923131 is ROHS3 compliant, while the 5352128-1 is RoHS compliant. Both meet regulatory requirements for their respective product statuses.

Q: What is the connector style designation "B 22," and is it consistent between both parts?

A: The B 22 designation refers to the specific connector style configuration within the backplane connector family. Both the 923131 and 5352128-1 share this identical style designation, ensuring mechanical and electrical compatibility.

Q: Are there any differences in contact finish specifications?

A: Both parts feature gold contact finish. The 5352128-1 specifies a contact finish thickness of 30.0µin (0.76µm), while the 923131 does not provide thickness specification. This difference does not affect substitution compatibility.

Q: What additional electrical ratings are provided for the 5352128-1?

A: The 5352128-1 specifies a current rating of 1.5 A and voltage rating of 500Vrms. These ratings define the electrical operating envelope for the substitute part and should be verified against application requirements.

Q: Is the alignment strip feature on the 5352128-1 significant for substitution?

A: The alignment strip is a mechanical feature that aids in assembly and positioning. Its presence on the 5352128-1 does not prevent substitution and may provide additional assembly benefits compared to the 923131.

Q: What is the connector usage designation "CompactPCI P2/P5" for the 5352128-1?

A: This designation indicates the intended application standard for the 5352128-1. The 923131 does not specify connector usage. Both parts are mechanically and electrically compatible regardless of intended application designation.
