TE Connectivity Erni 294670-E Backplane Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 294670-E is a 135-position backplane connector receptacle with female sockets, designed for board edge, through-hole, right-angle mounting applications. This connector operates with a 0.098" (2.50mm) pitch across a 9-row by 15-column configuration and utilizes press-fit termination technology.

The 294670-E is classified as an obsolete product. Identification of equivalent and substitute components is necessary to support legacy system maintenance, repair, and continued operational support where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 294670-E is evaluated based on the following critical parameters that define functional compatibility:

Primary Compatibility Criteria:

• Connector Type: Receptacle, Female Sockets
• Pitch: 0.098" (2.50mm)
• Termination Method: Press-Fit
• Mounting Configuration: Through Hole capability

Secondary Compatibility Considerations:

• Number of Positions and Row/Column Configuration
• Connector Category: Backplane Connectors
• Product Status and Availability

The substitute part 6469179-1 shares the core electrical and mechanical characteristics required for backplane connector applications. Both components utilize identical pitch spacing (0.098" / 2.50mm), press-fit termination, and through-hole mounting technology. The substitute maintains receptacle, female socket configuration and operates within the backplane connector category.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 294670-E is classified as obsolete, while the substitute part 6469179-1 maintains active product status with current manufacturing support and availability. The substitute is produced by TE Connectivity AMP Connectors, a primary manufacturer within the TE Connectivity portfolio.

Compliance and Certification: The substitute part 6469179-1 carries RoHS Compliance certification and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. The material flammability rating of UL94 V-0 indicates compliance with flame retardancy standards.

Electrical and Environmental Specifications: The substitute provides documented electrical ratings (0.700A current, 250V voltage) and operating temperature range (-65°C ~ 105°C), specifications not provided for the original part. These ratings establish the performance envelope for the substitute component.

Structural Differences: The substitute part 6469179-1 contains 90 positions across a 6-row by 15-column configuration, compared to the original 135 positions across 9 rows. The substitute utilizes through-hole mounting without the right-angle board edge configuration of the original. These dimensional and structural differences require evaluation against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 6469179-1 directly replace the 294670-E in all applications?

A: Direct replacement requires verification of position count and mounting configuration compatibility. The substitute contains 90 positions versus 135 positions in the original, and uses standard through-hole mounting rather than board edge, right-angle mounting. Application-specific requirements must be evaluated.

Q: What are the key electrical differences between these components?

A: The original 294670-E does not provide documented electrical specifications. The substitute 6469179-1 specifies 0.700A current rating and 250V voltage rating. Applications requiring different electrical parameters must be assessed independently.

Q: Are both components compatible with press-fit termination processes?

A: Yes. Both the 294670-E and 6469179-1 utilize press-fit termination technology, maintaining compatibility with standard press-fit assembly equipment and procedures.

Q: What is the significance of the pitch specification?

A: Both components share identical 0.098" (2.50mm) pitch spacing. This parameter defines the center-to-center distance between contact positions and is critical for PCB layout compatibility. Matching pitch ensures proper alignment with existing board designs.

Q: Does the substitute meet current regulatory requirements?

A: The 6469179-1 is RoHS Compliant and REACH Unaffected, meeting current regulatory standards for electronic component procurement. The original 294670-E does not provide compliance documentation.

Q: What packaging format is provided for the substitute part?

A: The 6469179-1 is supplied in tube packaging, as specified by the manufacturer.

Q: How does the row and column configuration differ between these parts?

A: The original 294670-E is configured as 9 rows by 15 columns (135 total positions). The substitute 6469179-1 is configured as 6 rows by 15 columns (90 total positions). The column count remains constant while the row count is reduced in the substitute.
