Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector 794628-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Number of rows (2)
• Pitch - mating (0.118" / 3.00mm)
• Row spacing - mating (0.118" / 3.00mm)
• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Series designation (Micro MATE-N-LOK)
• Insulation material (Polyamide / Nylon)
• Material flammability rating (UL94 V-0)

Packaging Variation: The substitute part 3-794628-4 differs only in packaging format (Tape & Reel versus standard packaging) and compliance certifications, while maintaining complete electrical and mechanical equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (794628-4): The 794628-4 is suitable for applications where RoHS non-compliant components are acceptable and standard packaging is required. This part carries MSL 1 rating, indicating unlimited shelf life without moisture control requirements.

Substitute Part Selection (3-794628-4): The 3-794628-4 is the direct functional equivalent with the following distinctions:

1. Compliance: The 3-794628-4 is ROHS3 compliant, making it the required selection for applications subject to RoHS regulations or customer specifications requiring RoHS compliance.

2. Packaging Format: The 3-794628-4 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The primary part uses standard packaging.

3. Contact Finish - Post: The 3-794628-4 features Tin finish on the post, compared to Tin-Lead on the primary part. Both finishes are compatible with solder termination processes.

4. Moisture Sensitivity: The 3-794628-4 carries MSL 2 rating (1 Year), requiring standard moisture control during storage and handling. The primary part has unlimited shelf life.

5. Inventory Availability: The 3-794628-4 has higher inventory availability (2416 pieces) compared to the primary part (742 pieces).

Both parts are active products from TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications for the Micro MATE-N-LOK series.

Frequently Asked Questions (FAQ)

Q: Are 794628-4 and 3-794628-4 electrically interchangeable?

A: Yes. Both parts are electrically identical with matching voltage ratings (250V), operating temperature ranges (-40°C ~ 105°C), contact materials (Brass with Gold mating finish), and all electrical specifications.

Q: What is the difference between these two parts?

A: The parts differ in four areas: packaging format (standard versus Tape & Reel), RoHS compliance status (non-compliant versus ROHS3 compliant), post contact finish (Tin-Lead versus Tin), and moisture sensitivity level (MSL 1 versus MSL 2).

Q: Can I use 3-794628-4 in place of 794628-4 in my assembly?

A: Yes, provided your application requirements permit ROHS3 compliance and your assembly process accommodates Tape & Reel packaging. The connector footprint, mating interface, and electrical performance are identical.

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

A: The 3-794628-4 is ROHS3 compliant and is the required selection for applications subject to RoHS regulations.

Q: What does MSL 2 (1 Year) mean for the 3-794628-4?

A: MSL 2 indicates the part requires moisture control during storage and handling, with a shelf life of one year under standard conditions (23°C, 50% relative humidity). The primary part (MSL 1) has unlimited shelf life without moisture control requirements.

Q: Are both parts suitable for automated assembly?

A: The 3-794628-4 is supplied in Tape & Reel format, which is standard for automated pick-and-place assembly. The primary part uses standard packaging, which may require manual handling or custom feeding systems.

Q: Do the different post contact finishes affect solder joint reliability?

A: Both Tin and Tin-Lead finishes are compatible with standard solder termination processes. The selection between them depends on your specific soldering process and application requirements.

Q: What is the mating pitch for both connectors?

A: Both connectors have a mating pitch of 0.118" (3.00mm) with identical row spacing of 0.118" (3.00mm).

Q: Are these connectors suitable for my general-purpose application?

A: Yes. Both parts are rated for general-purpose applications with a 4-position, 2-row configuration in the Micro MATE-N-LOK series.
