TE Connectivity 2-794626-0 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-794626-0 is a surface mount, right-angle rectangular connector header from the Micro MATE-N-LOK series. This connector is designed for board-to-cable/wire applications with 20 positions arranged in 2 rows at 0.118" (3.00mm) pitch. The part features shrouded 4-wall construction with solder termination and locking ramp fastening. The connector maintains an operating temperature range of -40°C to 105°C and is rated for 250V applications. This part is currently active in production with 1089 pieces in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific packaging or compliance requirements necessitate component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for substitution of the TE Connectivity 2-794626-0 are:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (20)
• Number of rows (2)
• Pitch - mating (0.118" / 3.00mm)
• Row spacing - mating (0.118" / 3.00mm)
• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Operating temperature range (-40°C ~ 105°C)
• Voltage rating (250V)
• Series designation (Micro MATE-N-LOK)

The substitute part 5-794626-0 maintains identical electrical and mechanical specifications across all critical parameters. Differences exist only in packaging format and compliance certifications, which do not affect functional interchangeability in the connector application.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 2-794626-0 and 5-794626-0 are active production parts from the same manufacturer and series. The parts are electrically and mechanically identical across all functional parameters required for rectangular connector header applications.

Selection Criteria:

The 2-794626-0 is suitable for applications where moisture sensitivity level 1 (unlimited shelf life) is required and where RoHS compliance status is not a specification requirement.

The 5-794626-0 is suitable for applications requiring ROHS3 compliance certification. This part carries a moisture sensitivity level of 2, requiring storage conditions of 1 year maximum at specified humidity levels. The 5-794626-0 is supplied in Cut Tape (CT) packaging format and currently maintains higher inventory availability at 2028 pieces.

Both parts operate across the identical temperature range of -40°C to 105°C and maintain the same 250V voltage rating. Selection between these parts depends on specific compliance requirements, packaging format preferences, and moisture sensitivity constraints of the end application.

Frequently Asked Questions (FAQ)

Q: Are the 2-794626-0 and 5-794626-0 connectors mechanically interchangeable?

A: Yes. Both connectors maintain identical mechanical specifications including 20 positions, 2-row configuration, 0.118" (3.00mm) pitch, surface mount right-angle mounting, shrouded 4-wall construction, and solder termination. They are mechanically interchangeable in board-to-cable/wire applications.

Q: Are the 2-794626-0 and 5-794626-0 connectors electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 250V voltage rating, male pin contact type, brass contact material with gold mating finish, and operating temperature range of -40°C to 105°C. They are electrically interchangeable for general purpose applications.

Q: What is the difference between the 2-794626-0 and 5-794626-0?

A: The primary differences are packaging format and compliance certifications. The 5-794626-0 is supplied in Cut Tape (CT) packaging and carries ROHS3 compliance certification. The 2-794626-0 has unspecified packaging and RoHS status listed as not applicable. The 5-794626-0 has a moisture sensitivity level of 2 (1 year), while the 2-794626-0 has MSL 1 (unlimited).

Q: Which part should I select for RoHS-compliant applications?

A: The 5-794626-0 is certified ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance documentation.

Q: What is the moisture sensitivity level difference between these parts?

A: The 2-794626-0 has MSL 1 (unlimited shelf life without moisture control). The 5-794626-0 has MSL 2, requiring storage at controlled humidity conditions for a maximum of 1 year. MSL 1 parts have less stringent storage requirements than MSL 2 parts.

Q: What packaging formats are available?

A: The 5-794626-0 is supplied in Cut Tape (CT) packaging. The 2-794626-0 packaging format is not specified in the available documentation.

Q: Can I use the 5-794626-0 as a direct replacement for the 2-794626-0?

A: Yes, the 5-794626-0 is a direct functional replacement for the 2-794626-0 in all electrical and mechanical applications. Selection should be based on specific compliance requirements and packaging preferences.

Q: Are both parts currently in production?

A: Yes, both the 2-794626-0 and 5-794626-0 are active production parts from TE Connectivity AMP Connectors.
