Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A3C-10DA-2DSA(71) is determined by strict alignment of the following critical parameters:

Mechanical Compatibility Requirements:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 10
• Pitch - mating: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Through hole
• Termination: Solder
• Fastening type: Push-pull

Electrical Performance Requirements:

• Contact finish - mating: Gold
• Operating temperature range: Minimum -55°C, maximum 85°C or higher
• Current rating: 1A or greater
• Voltage rating: 200VAC or greater
• Material flammability rating: UL94 V-0

Regulatory & Environmental Requirements:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The SMM-105-01-S-D from Samtec Inc. meets all critical mechanical and electrical parameters while exceeding minimum performance thresholds in current rating (3.2A per contact) and voltage rating (350VAC). Both parts maintain identical pitch, row configuration, and termination method, ensuring direct mechanical and electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the A3C-10DA-2DSA(71) and SMM-105-01-S-D are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings, meeting current regulatory requirements. The SMM-105-01-S-D provides enhanced electrical performance margins with higher current rating (3.2A per contact versus 1A) and voltage rating (350VAC versus 200VAC), along with an extended operating temperature range (-55°C to 125°C versus -55°C to 85°C). Both connectors maintain identical mechanical interfaces, pitch specifications, and termination methods, ensuring direct substitution capability. Selection between these parts should be based on availability, lead time, and application-specific performance requirements within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the SMM-105-01-S-D be used as a direct replacement for the A3C-10DA-2DSA(71)?

A: Yes. Both connectors share identical mechanical and electrical specifications for pitch (0.079" / 2.00mm), number of positions (10), row configuration (2 rows), mounting type (through hole), termination method (solder), and fastening type (push-pull). The SMM-105-01-S-D meets or exceeds all electrical performance requirements of the original part.

Q: What are the key differences between these two connectors?

A: The primary differences are in contact material composition (phosphor bronze versus beryllium copper), insulation material (PBT versus LCP), contact finish thickness on mating surfaces, and performance ratings. The SMM-105-01-S-D provides higher current capacity (3.2A per contact), higher voltage rating (350VAC), and extended temperature range (-55°C to 125°C).

Q: Are both parts RoHS compliant?

A: Yes. Both the A3C-10DA-2DSA(71) and SMM-105-01-S-D are ROHS3 compliant and meet REACH requirements.

Q: What is the packaging difference between these parts?

A: The A3C-10DA-2DSA(71) is supplied in trays, while the SMM-105-01-S-D is supplied in tubes. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Can these connectors be mated with the same plug connector?

A: Compatibility depends on the plug connector specifications. Both receptacles share identical pitch (0.079" / 2.00mm) and row spacing (0.079" / 2.00mm), so they will accept plug connectors designed for 2-row, 10-position 2.00mm pitch configurations. Verify plug connector specifications against both receptacle dimensions and contact geometry.

Q: What is the moisture sensitivity level for both parts?

A: Both connectors have a moisture sensitivity level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
