Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-1877846-5 is determined by alignment across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug, Male Pins)
• Number of positions (6)
• Termination method (Solder Cup)
• Contact finish material (Gold plating)
• Current and voltage ratings within acceptable operating ranges

Mechanical Compatibility Parameters:

• Mounting configuration (Free Hanging, In-Line)
• Shell material composition (Thermoplastic)
• Contact material base (Copper Alloy)
• Cable opening dimensions compatible with standard solder cup interfaces

Regulatory and Environmental Parameters:

• RoHS compliance status
• Moisture sensitivity level (MSL 1 - Unlimited)
• Operating temperature envelope compatibility

The Switchcraft Inc. EN3C6MX meets the core electrical and mechanical substitution criteria as a 6-position male plug connector with solder cup termination, gold-plated contacts, and thermoplastic construction. Both parts maintain RoHS compliance and MSL 1 rating, supporting direct functional replacement in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TE Connectivity 2-1877846-5 remains the specified component for applications requiring the full operating temperature range of -50°C to 170°C and voltage rating of 300VAC. This part maintains active product status with established inventory availability and Medical CPC series certification.

Substitute Part Selection: The Switchcraft EN3C6MX serves as a functional substitute for applications operating within the constraints of 250VAC/DC maximum voltage and -40°C to 65°C temperature range. The EN3C6MX provides equivalent 6-position male plug solder cup connectivity with gold-plated contacts and copper alloy construction. The substitute part offers enhanced ingress protection (IP66/IP68) and higher current rating (7.5A), supporting general purpose, instrumentation, marine, and medical applications.

Compatibility Constraints: The EN3C6MX employs a Bayonet Lock fastening mechanism and keyed orientation, differing from the TE part's Latch Lock and 0° orientation. These mechanical interface differences require physical verification of mating socket compatibility before deployment. The reduced operating temperature ceiling of the EN3C6MX (-40°C to 65°C versus -50°C to 170°C) restricts its use in high-temperature medical applications.

Regulatory Compliance: Both parts maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity ratings, supporting deployment in regulated medical device environments. The EN3C6MX meets current ROHS3 standards, while the TE part maintains RoHS Compliant status.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft EN3C6MX directly replace the TE Connectivity 2-1877846-5 in all applications?

A: Direct replacement is limited by operating temperature and voltage specifications. The EN3C6MX operates at maximum 250VAC/DC and -40°C to 65°C, compared to the TE part's 300VAC and -50°C to 170°C range. Applications requiring the full temperature or voltage envelope of the TE part cannot use the EN3C6MX as a substitute. Additionally, the different fastening mechanisms (Bayonet Lock versus Latch Lock) require socket compatibility verification.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: 6-position connector configuration, male pin plug type, solder cup termination, gold-plated mating contacts, copper alloy contact material, and current/voltage ratings meeting or exceeding the application requirements. Both parts satisfy these core electrical parameters within their respective operating envelopes.

Q: How do the mechanical interfaces differ between these connectors?

A: The TE Connectivity 2-1877846-5 uses a Latch Lock fastening mechanism with 0° orientation, while the Switchcraft EN3C6MX employs a Bayonet Lock with keyed orientation. These differences affect physical mating with socket connectors and require confirmation of mechanical compatibility before substitution.

Q: Are both parts suitable for medical device applications?

A: Both parts maintain RoHS compliance and MSL 1 ratings supporting medical applications. The TE part is specifically designated for the Medical CPC series, while the EN3C6MX lists medical among its general purpose, instrumentation, and marine applications. Application-specific medical device requirements and temperature/voltage constraints must be evaluated independently.

Q: What is the significance of the cable opening dimensions?

A: Cable opening dimensions define the acceptable wire gauge range for solder cup termination. The TE part specifies 0.209" to 0.256" (5.30mm to 6.50mm), while the EN3C6MX accepts 0.160" to 0.265" (4.06mm to 6.73mm). The EN3C6MX range overlaps and extends the TE part range, accommodating a broader wire gauge selection while maintaining solder cup integrity.

Q: What inventory considerations apply to these parts?

A: The TE Connectivity 2-1877846-5 maintains 998 pieces in current inventory as a new original part. The Switchcraft EN3C6MX provides 2649 pieces in bulk packaging. Inventory availability may influence sourcing decisions when primary part stock is depleted, provided application parameters align with the substitute part specifications.

Q: How do the ingress protection ratings affect application suitability?

A: The TE Connectivity 2-1877846-5 does not specify an ingress protection rating, while the Switchcraft EN3C6MX provides IP66/IP68 protection (dust tight, water resistant, waterproof). Applications requiring enhanced environmental sealing benefit from the EN3C6MX specification, though this feature is not required for standard medical connector applications.
