Key Parameters

Substitute Part Grouping Explanation

Substitution of the 104088-E is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector type: Receptacle, Female Sockets
• Number of positions: 88
• Pitch: 0.079" (2.00mm)
• Number of rows: 8
• Mounting type: Through Hole, Right Angle
• Termination method: Press-Fit
• Contact finish: Gold
• Operating temperature range: -55°C ~ 125°C
• Connector style: F 11

Substitution Classification:

The part 5646446-1 qualifies as a manufacturer-recommended substitute. This part maintains all critical electrical and mechanical parameters while offering active product status and enhanced specifications including defined voltage rating (750Vrms) and current rating (1.5A).

The part 646446-1 qualifies as a similar substitute with identical mechanical and electrical specifications to 5646446-1. However, this part exhibits non-compliance with RoHS3 standards and REACH-affected status, distinguishing it from the primary substitute recommendation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5646446-1

The TE Connectivity AMP Connectors part 5646446-1 is the manufacturer-recommended substitute for the obsolete 104088-E. This part maintains full mechanical and electrical compatibility while offering active product status. The part achieves ROHS3 compliance and REACH unaffected status, aligning with current regulatory requirements. The defined electrical specifications (750Vrms voltage rating, 1.5A current rating) and contact finish thickness (30.0µin) provide enhanced documentation for design verification. Inventory availability of 2956 units supports procurement continuity.

Secondary Substitute: 646446-1

The TE Connectivity AMP Connectors part 646446-1 provides identical mechanical and electrical specifications to 5646446-1 with equivalent performance characteristics. However, this part does not meet ROHS3 compliance requirements and carries REACH-affected status. Selection of this part is appropriate only for applications where regulatory compliance exemptions apply or legacy system maintenance is required. Inventory availability of 888 units is lower than the primary substitute.

Compliance Considerations:

For applications requiring ROHS3 compliance and REACH unaffected status, 5646446-1 is the appropriate selection. For applications without regulatory compliance requirements, 646446-1 provides a cost-effective alternative with identical functional performance.

Frequently Asked Questions (FAQ)

Q: What makes 5646446-1 a valid substitute for 104088-E?

A: The 5646446-1 maintains all critical mechanical and electrical parameters: 88 positions, 2.00mm pitch, 8 rows, F 11 connector style, press-fit termination, gold contact finish, and -55°C to 125°C operating temperature range. Both parts are receptacle connectors with female sockets and right-angle through-hole mounting. The substitute is active product status, addressing the obsolescence of the original part.

Q: What is the difference between 5646446-1 and 646446-1?

A: Both parts are functionally identical with matching mechanical specifications and electrical ratings (750Vrms, 1.5A). The primary differences are regulatory compliance: 5646446-1 is ROHS3 compliant and REACH unaffected, while 646446-1 is RoHS non-compliant and REACH affected. Inventory levels also differ, with 5646446-1 having higher availability (2956 units versus 888 units).

Q: Are there packaging differences between the main part and substitutes?

A: The original 104088-E is supplied in Tray packaging. The recommended substitute 5646446-1 is supplied in Bulk packaging. The similar substitute 646446-1 has unspecified packaging. Packaging differences do not affect connector functionality but may impact receiving, storage, and handling procedures.

Q: Can 104088-E be directly replaced with 5646446-1 on existing PCBs?

A: Both connectors feature identical pitch (2.00mm), position count (88), row configuration (8), and right-angle through-hole mounting. The mechanical footprint and electrical interface are compatible. The mounting designation difference (main part specifies "Through Hole, Right Angle" while substitute specifies "Board Edge, Through Hole, Right Angle") indicates the substitute includes board edge contact capability, providing equivalent or enhanced functionality.

Q: What are the electrical specifications for the substitute parts?

A: The 5646446-1 and 646446-1 substitutes are rated for 750Vrms voltage and 1.5A current. The original 104088-E does not specify these electrical ratings in available documentation. The substitute specifications represent defined performance parameters suitable for design verification and application validation.

Q: Which substitute should be selected for new designs?

A: For new designs, 5646446-1 is the appropriate selection. This part offers active product status, ROHS3 compliance, REACH unaffected status, and higher inventory availability. These characteristics ensure long-term supply continuity and regulatory alignment for production applications.
