Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 3-1877846-5 are identified based on the following critical parameters that determine functional equivalency:

Electrical Compatibility Parameters:

• Connector type (Plug, Male Pins)
• Number of positions (6)
• Termination method (Solder Cup)
• Contact finish (Gold)
• Contact material (Copper Alloy)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging/In-Line)
• Shell material (Thermoplastic)
• Primary material (Plastic)

Performance Parameters:

• Current rating capability
• Voltage rating capability
• Operating temperature range
• Compliance certifications (RoHS status)

The substitute part EN3C6MX from Switchcraft Inc. shares the core electrical and mechanical characteristics required for circular connector plug applications with 6 positions, male pins, solder cup termination, and gold-plated contacts. Both parts maintain copper alloy contact material and thermoplastic shell construction.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 3-1877846-5 is the primary component specified for applications requiring the Medical CPC series designation. This part maintains Active product status with RoHS Compliant certification and is optimized for medical applications with an extended operating temperature range of -50°C to 170°C.

Switchcraft EN3C6MX serves as a functional substitute for general-purpose circular connector applications. This part is ROHS3 Compliant and rated for higher current capacity (7.5A versus 6A). The EN3C6MX operates within a narrower temperature range (-40°C to 65°C) and lower voltage rating (250VAC/DC versus 300VAC). Selection of the Switchcraft substitute requires verification that the reduced operating temperature range and voltage rating are acceptable for the intended application.

Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft EN3C6MX directly replace the TE Connectivity 3-1877846-5 in all applications?

A: Direct replacement is limited by operating temperature and voltage specifications. The EN3C6MX operates between -40°C and 65°C, compared to the TE Connectivity part's -50°C to 170°C range. The EN3C6MX is rated for 250VAC/DC versus 300VAC for the TE Connectivity part. Applications requiring the full temperature or voltage range of the original part cannot use the EN3C6MX as a substitute.

Q: What are the key electrical parameters that must match for substitution?

A: The critical electrical parameters are connector type (Plug, Male Pins), number of positions (6), termination method (Solder Cup), contact finish (Gold), and contact material (Copper Alloy). Both parts meet these requirements.

Q: Are there differences in fastening mechanisms between these parts?

A: Yes. The TE Connectivity 3-1877846-5 uses a Latch Lock fastening type with 80° orientation. The Switchcraft EN3C6MX uses a Bayonet Lock fastening type with Keyed orientation. These differences affect mating interface compatibility and must be considered in connector pair selection.

Q: What is the significance of the different insert materials?

A: The TE Connectivity part uses Polyphenylene Sulfide (PPS) insert material, while the Switchcraft part uses Elastomer insert material. This affects mechanical durability and environmental resistance characteristics but does not prevent functional substitution in applications where the operating environment is compatible with elastomer materials.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage, handling, or assembly.

Q: What packaging differences exist between these parts?

A: The TE Connectivity 3-1877846-5 is supplied in unspecified packaging with 862 pieces in stock. The Switchcraft EN3C6MX is supplied in Bulk packaging with 2649 pieces in stock. Packaging format may affect procurement and inventory management but does not affect functional performance.

Q: Are both parts compliant with current regulatory standards?

A: Yes. The TE Connectivity part is RoHS Compliant. The Switchcraft part is ROHS3 Compliant, representing a more recent revision of the RoHS directive. Both parts are classified as EAR99 for export control purposes and share identical HTSUS tariff classification (8536.69.4020).
