Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 104935 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 176
• Pitch: 0.079" (2.00mm)
• Connector Style: D 22
• Number of Rows: 8
• Termination Method: Press-Fit
• Contact Finish: Gold
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Configuration: Through Hole, Right Angle

The substitute parts identified (5646486-1 and 646486-1) satisfy all mandatory matching parameters. Both alternatives are manufactured by TE Connectivity AMP Connectors and belong to the Z-PACK series. These parts maintain functional and mechanical compatibility with the obsolete 104935 while offering active product status and enhanced electrical specifications.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5646486-1

The 5646486-1 is designated as the manufacturer-recommended substitute for the obsolete 104935. This part maintains complete electrical and mechanical compatibility across all critical parameters. The 5646486-1 offers active product status, ensuring long-term availability and supply chain continuity. The part is RoHS Compliant and provides documented electrical specifications (1.5 A current rating, 750Vrms voltage rating) not specified in the original 104935. The upper shield feature provides enhanced electromagnetic shielding for backplane applications. Packaging is supplied in tube format.

Secondary Substitute: TE Connectivity AMP Connectors 646486-1

The 646486-1 serves as an alternative equivalent with identical electrical and mechanical specifications to the 5646486-1. This part maintains active product status and Z-PACK series compatibility. RoHS status is listed as not applicable. Packaging format is not specified. The 646486-1 is suitable for applications where the primary substitute is unavailable.

Both substitute parts are manufactured by TE Connectivity and maintain the same connector architecture, pitch, position count, and termination method as the original 104935, ensuring direct functional replacement in backplane connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 5646486-1 directly replace the obsolete 104935 in existing designs?

A: Yes. The 5646486-1 maintains identical electrical and mechanical specifications across all critical parameters: 176 positions, 2.00mm pitch, D 22 connector style, 8 rows, press-fit termination, gold contacts, and -55°C to 125°C operating temperature range. The mounting configuration (through hole, right angle) is functionally equivalent.

Q: What is the difference between the 5646486-1 and 646486-1 substitutes?

A: Both parts are electrically and mechanically equivalent with identical position count, pitch, connector style, and termination specifications. The primary differences are packaging format (5646486-1 supplied in tube; 646486-1 packaging not specified) and RoHS compliance documentation (5646486-1 is RoHS Compliant; 646486-1 status is not applicable).

Q: Are there any compatibility concerns when substituting the 104935 with the 5646486-1?

A: No compatibility concerns exist for the specified electrical and mechanical parameters. Both connectors feature identical pitch, position count, connector style, and mounting configuration. The substitute provides documented electrical ratings (1.5 A, 750Vrms) and enhanced shielding features not specified in the original part.

Q: What is the significance of the upper shield feature in the 5646486-1?

A: The upper shield feature provides electromagnetic shielding for backplane connector applications. This is a functional enhancement that does not affect mechanical or electrical compatibility with the original 104935.

Q: How does the packaging difference affect part selection?

A: The 5646486-1 is supplied in tube packaging, while the original 104935 was supplied in tray packaging. Packaging format affects handling, storage, and ordering quantities but does not impact electrical or mechanical performance. Selection should be based on procurement and assembly process requirements.

Q: Is the 104935 still available for purchase?

A: The 104935 is classified as obsolete. Inventory availability is limited to existing stock (1189 pieces reported). For new designs and ongoing production, the active substitutes 5646486-1 or 646486-1 are recommended to ensure long-term supply chain continuity.

Q: What compliance certifications apply to the substitute parts?

A: The 5646486-1 is RoHS Compliant and REACH Unaffected. The 646486-1 RoHS status is not applicable, and REACH status is vendor undefined. Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4040. Compliance requirements should be verified against specific application and regulatory standards.
