Key Parameters

Substitute Part Grouping Explanation

The Switchcraft Inc. EN3C6MX is identified as a substitute for the TE Connectivity 6-1877846-3 based on the following alignment of core electrical and mechanical parameters:

Matching Parameters:

• 6-position circular connector configuration
• Male pin plug connector type
• Solder cup termination method
• Gold-plated mating contacts
• Copper alloy contact material
• Free hanging in-line mounting
• Thermoplastic shell construction
• RoHS compliance status
• MSL Level 1 (Unlimited) moisture sensitivity
• EAR99 ECCN classification
• Identical HTSUS code (8536.69.4020)

Functional Equivalence Basis: Both connectors serve identical functional roles as 6-position male plug connectors with solder cup termination and gold contact plating. The substitution is valid where the electrical and mechanical interface requirements are satisfied by the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TE Connectivity 6-1877846-3 remains the specified component for applications requiring the full operating temperature range of -50°C to 170°C and 300VAC voltage rating. This part is Active status with established RoHS Compliance and unlimited moisture sensitivity rating.

Substitute Part Selection: The Switchcraft Inc. EN3C6MX serves as a functional substitute where application requirements align with its electrical and mechanical specifications. The EN3C6MX provides higher current capacity (7.5A versus 6A) and maintains RoHS3 Compliance status. Selection of the substitute part is appropriate when:

• Operating temperature requirements fall within the -40°C to 65°C range
• Voltage requirements do not exceed 250VAC/DC
• Cable opening dimensions accommodate the 0.160" to 0.265" specification
• Bayonet lock fastening and keyed orientation are compatible with the application interface

Both parts maintain Active product status, unlimited MSL rating, and identical ECCN/HTSUS classifications, supporting regulatory and supply chain consistency.

Frequently Asked Questions (FAQ)

Q: Can the EN3C6MX substitute for the 6-1877846-3 in all medical applications?

A: The EN3C6MX is functionally equivalent for 6-position male plug solder cup connector applications where operating temperature remains between -40°C and 65°C and voltage does not exceed 250VAC/DC. Medical applications requiring the full -50°C to 170°C temperature range or 300VAC rating require the primary TE Connectivity part.

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

A: The primary differences are operating temperature range (-50°C to 170°C for 6-1877846-3 versus -40°C to 65°C for EN3C6MX), voltage rating (300VAC versus 250VAC/DC), current capacity (6A versus 7.5A), fastening mechanism (Latch Lock versus Bayonet Lock), and cable opening dimensions (0.106"-0.154" versus 0.160"-0.265").

Q: Are both connectors RoHS compliant?

A: Yes. The 6-1877846-3 is RoHS Compliant, and the EN3C6MX is ROHS3 Compliant. Both meet RoHS requirements and maintain identical ECCN and HTSUS classifications.

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

A: Both connectors carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Do these connectors have different mating interfaces?

A: Both connectors feature 6-position male pin configurations with gold-plated copper alloy contacts and solder cup termination. However, the fastening types differ: the 6-1877846-3 uses Latch Lock fastening with 0° orientation, while the EN3C6MX uses Bayonet Lock fastening with keyed orientation. These differences affect mechanical coupling compatibility.

Q: What is the cable opening specification, and why does it matter?

A: Cable opening specifies the acceptable cable diameter range for proper strain relief and sealing. The 6-1877846-3 accommodates 0.106" to 0.154" (2.70mm to 3.90mm) cable diameter, while the EN3C6MX accommodates 0.160" to 0.265" (4.06mm to 6.73mm). Cable diameter must fall within the specified range for proper connector function.

Q: Can I use the EN3C6MX in applications requiring -50°C operation?

A: No. The EN3C6MX operating temperature range is -40°C to 65°C. Applications requiring -50°C operation require the TE Connectivity 6-1877846-3.

Q: Are both parts available in equivalent packaging quantities?

A: The 6-1877846-3 is available with 1081 pieces in stock, while the EN3C6MX is available with 2649 pieces in bulk packaging. Packaging format and availability differ between suppliers.
