Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity Erni 104933 is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 110
• Pitch: 0.079" (2.00mm)
• Number of rows: 5
• Connector style: AB 22
• Mounting configuration: Board Edge, Through Hole, Right Angle
• Contact finish: Gold
• Operating temperature range: -55°C ~ 125°C
• Moisture sensitivity level: 1 (Unlimited)

Variable Parameters Permitting Substitution:

• Termination method (Press-Fit vs. Solder)
• Packaging format (Tray, Tube, or Bulk)
• Product status (Obsolete vs. Active)
• RoHS compliance status
• Manufacturer designation within TE Connectivity product lines

The substitute parts identified below maintain full electrical and mechanical compatibility with the original 104933 specification while offering active product status and improved supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5646573-1

The 5646573-1 is designated as the manufacturer-recommended substitute for the obsolete 104933. This part maintains identical electrical and mechanical specifications while offering active product status. The 5646573-1 features press-fit termination matching the original design, RoHS compliance certification, and availability in tube packaging. Selection of this part eliminates obsolescence risk and ensures long-term supply chain viability.

Secondary Substitute: TE Connectivity AMP Connectors 646573-1

The 646573-1 provides functional equivalence with a critical termination difference: solder termination replaces the press-fit method of the original 104933. This substitution is applicable only when board design accommodates solder termination methodology. The 646573-1 carries RoHS non-compliant status and REACH-affected designation, requiring regulatory assessment for applications subject to environmental compliance mandates. Bulk packaging format supports high-volume production requirements.

Compliance Considerations:

Applications requiring ROHS3 compliance must utilize the 5646573-1 substitute. The 646573-1 is unsuitable for designs subject to RoHS or REACH regulatory frameworks. Both substitute parts maintain identical operating temperature ranges and moisture sensitivity ratings as the original 104933.

Frequently Asked Questions (FAQ)

Q: Can the 5646573-1 directly replace the 104933 without PCB redesign?

A: Yes. The 5646573-1 maintains identical pitch, position count, row configuration, connector style, and mounting orientation. Press-fit termination compatibility eliminates the need for board layout modification.

Q: What is the primary difference between the 5646573-1 and 646573-1 substitutes?

A: Termination method differs: the 5646573-1 uses press-fit termination identical to the original 104933, while the 646573-1 requires solder termination. The 646573-1 also lacks board edge mounting specification. Selection depends on existing PCB design and assembly process capability.

Q: Is the 646573-1 suitable for new designs requiring RoHS compliance?

A: No. The 646573-1 carries RoHS non-compliant and REACH-affected designations. For applications subject to environmental compliance requirements, the 5646573-1 is the appropriate selection.

Q: Do the substitute parts support the same current and voltage ratings as the original 104933?

A: The substitute parts specify 1.5 A current rating and 500Vrms voltage rating. The original 104933 does not provide these electrical specifications in the available documentation. Both substitutes operate within the identical -55°C to 125°C temperature range.

Q: What packaging formats are available for each substitute?

A: The 5646573-1 is supplied in tube packaging. The 646573-1 is supplied in bulk packaging. The original 104933 was supplied in tray packaging. Packaging selection affects handling, storage, and integration into automated assembly processes.

Q: Are both substitute parts manufactured by TE Connectivity?

A: Yes. Both 5646573-1 and 646573-1 are manufactured by TE Connectivity AMP Connectors division, ensuring design consistency and quality standards aligned with the original ERMET series 104933.
