TE Connectivity 104550-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104550-9 is a 100 Position Receptacle Connector designed for 0.050" (1.27mm) pitch board-to-board applications with surface mount termination. This connector is part of the AMPMODU System 50 series and features gold-plated mating contacts with tin-lead post finish. The component maintains Active product status and is suitable for applications requiring push-pull fastening and board lock functionality across the operating temperature range of -65°C to 105°C.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained, including connector type, position count, pitch specifications, mounting configuration, and contact materials. Substitution becomes necessary when addressing component availability, compliance requirements, or inventory optimization while preserving functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 104550-9 and the equivalent part 5-104550-9 is based on strict electrical and mechanical parameter equivalence. Both components share identical specifications across all critical substitution criteria:

Electrical Parameters:

• 100 position count with 2-row configuration
• 0.050" (1.27mm) mating pitch
• 0.100" (2.54mm) row spacing
• 30VAC voltage rating
• Phosphor bronze contact material with gold mating finish

Mechanical Parameters:

• Surface mount solder termination
• Female socket contact type
• Board-to-board receptacle configuration
• Push-pull fastening with board lock
• 0.370" (9.40mm) insulation height
• Mated stacking heights of 11.94mm and 13.08mm

Environmental Parameters:

• Operating temperature range: -65°C to 105°C
• UL94 V-0 flammability rating
• Moisture Sensitivity Level 1 (Unlimited)

The primary distinction between these parts exists in post finish specification and regulatory compliance status, which do not affect mechanical or electrical interchangeability in board-to-board mating applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 104550-9 and 5-104550-9 are functionally equivalent for board-to-board receptacle applications requiring 100 positions at 0.050" pitch with surface mount solder termination. Selection between these parts is determined by regulatory and compliance requirements rather than electrical or mechanical performance.

104550-9 Selection Criteria:

• Applications where RoHS non-compliance is acceptable or required
• Tin-lead post finish specification is mandated
• REACH Affected status is compatible with supply chain requirements

5-104550-9 Selection Criteria:

• Applications requiring ROHS3 compliance
• Tin post finish is acceptable for solder termination
• Vendor-undefined REACH status is compatible with procurement specifications
• Higher inventory availability (7009 pcs vs. 793 pcs) supports production scheduling

Both parts maintain identical electrical performance, mechanical dimensions, and environmental operating specifications. The post finish difference (tin-lead versus tin) does not affect mating contact performance, as the mating surface finish remains gold-plated at 30.0µin thickness in both configurations.

Frequently Asked Questions (FAQ)

Q: Are the 104550-9 and 5-104550-9 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including 100 positions, 0.050" mating pitch, 2-row configuration, surface mount termination, and mated stacking heights of 11.94mm and 13.08mm. Board-to-board mating compatibility is fully maintained.

Q: What is the difference between the tin-lead and tin post finishes?

A: The post finish applies to the solder termination interface, not the mating contact surface. Both parts feature identical gold mating contact finish at 30.0µin thickness. The post finish difference does not affect electrical performance or mating reliability in board-to-board applications.

Q: Which part should be selected for RoHS-compliant applications?

A: The 5-104550-9 is ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance. The 104550-9 is RoHS non-compliant.

Q: Are there any temperature or voltage rating differences?

A: No. Both parts operate across the identical temperature range of -65°C to 105°C and maintain a 30VAC voltage rating. Environmental performance specifications are equivalent.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that the design does not specify RoHS compliance or post finish requirements. The electrical and mechanical specifications are identical, ensuring functional compatibility in board-to-board receptacle applications.

Q: What is the significance of the different REACH statuses?

A: The 104550-9 lists REACH Affected status, while the 5-104550-9 lists Vendor Undefined status. This distinction relates to regulatory documentation and supply chain compliance tracking. Selection depends on procurement and regulatory requirements specific to the application.

Q: Do both parts support the same mating connector types?

A: Yes. Both receptacle connectors are designed for the AMPMODU System 50 series and accept identical plug connectors with 100 positions at 0.050" pitch. Mating compatibility is fully maintained.

Q: What is the Moisture Sensitivity Level for both parts?

A: Both parts are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
