Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 104656-2 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Number of positions: 20
• Number of rows: 2
• Pitch - mating: 0.050" (1.27mm)
• Row spacing - mating: 0.050" (1.27mm)
• Connector type: Header
• Contact type: Male Pin
• Mounting type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening type: Push-Pull

Electrical Performance Parameters:

• Current rating: 0.5A per Contact
• Operating temperature range: -65°C ~ 105°C
• Contact material: Phosphor Bronze
• Contact finish - mating: Gold

Environmental & Compliance Parameters:

• Material flammability rating: UL94 V-0
• Insulation material: Liquid Crystal Polymer (LCP)
• Moisture sensitivity level: 1 (Unlimited)
• Series: AMPMODU 50/50 Grid

The substitute part 5-104656-2 maintains full equivalence across all mechanical, electrical, and environmental parameters. Variations in post-contact finish material (Tin-Lead versus Tin) and RoHS compliance status do not affect functional interchangeability for board-to-board mating applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 104656-2 and 5-104656-2 are classified as Active product status and maintain full functional equivalence for board-to-board rectangular connector applications. Selection between these parts should be based on the following criteria:

Compliance Requirements: The 5-104656-2 variant carries ROHS3 Compliant certification, making it the appropriate selection for applications subject to Restriction of Hazardous Substances regulations. The 104656-2 is marked as "Not applicable" for RoHS status and should be selected only when RoHS compliance is not a design requirement.

Post-Contact Finish Consideration: The 104656-2 features Tin-Lead post-contact finish, while the 5-104656-2 features Tin post-contact finish. Both maintain identical contact finish thickness (150.0µin / 3.81µm) and do not affect mating performance. Selection should align with soldering process specifications and lead-free manufacturing requirements.

Supply Chain Availability: The 5-104656-2 maintains higher inventory availability (4339 Pcs) compared to the 104656-2 (792 Pcs), supporting procurement continuity for high-volume production schedules.

Both parts are suitable for automotive, general purpose, medical, military, and telecommunications applications within the specified operating temperature range of -65°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Are the 104656-2 and 5-104656-2 mechanically interchangeable?

A: Yes. Both parts maintain identical mechanical specifications including 20-position configuration, 1.27mm pitch, dual-row layout, shrouded 4-wall design, and surface mount termination. They are fully interchangeable in board-to-board mating applications.

Q: What is the difference between the post-contact finishes?

A: The 104656-2 uses Tin-Lead post-contact finish, while the 5-104656-2 uses Tin post-contact finish. Both maintain the same contact finish thickness of 150.0µin (3.81µm). The selection depends on soldering process compatibility and lead-free manufacturing requirements.

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

A: The 5-104656-2 is ROHS3 Compliant and is the appropriate selection for applications requiring RoHS compliance. The 104656-2 is marked as "Not applicable" for RoHS status.

Q: Do both parts support the same current and temperature specifications?

A: Yes. Both parts are rated for 0.5A per contact and operate across the identical temperature range of -65°C to 105°C. They share identical material flammability rating (UL94 V-0) and insulation material (Liquid Crystal Polymer).

Q: Are there any differences in packaging or inventory considerations?

A: Both parts are supplied in tube packaging. The 5-104656-2 has significantly higher inventory availability (4339 Pcs) compared to the 104656-2 (792 Pcs), which may influence procurement decisions for high-volume applications.

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

A: Yes. The parts are functionally equivalent across all critical mechanical, electrical, and environmental parameters. Design documentation should specify either part number or allow both as acceptable alternatives based on compliance and supply chain requirements.

Q: What applications are these connectors suitable for?

A: Both parts are rated for automotive, general purpose, medical, military, and telecommunications applications. The UL94 V-0 flammability rating and LCP insulation material support demanding environmental conditions across these sectors.
