Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2-1877846-1 is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Connector type must be Plug with Male Pins
• Number of positions must equal 6
• Termination method must be Solder Cup
• Contact finish must be Gold
• Current rating must meet or exceed 6A
• Voltage rating must meet or exceed 300VAC

Mechanical Compatibility Parameters:

• Mounting type must be Free Hanging (In-Line)
• Contact material must be Copper Alloy
• Operating temperature range must encompass the application requirements

Compliance Parameters:

• RoHS compliance status must be active (RoHS Compliant or ROHS3 Compliant)
• Moisture Sensitivity Level must be 1 (Unlimited)

The substitute part EN3C6MX from Switchcraft Inc. meets these core substitution criteria, enabling functional equivalence in applications requiring a 6-position male plug connector with solder cup termination and gold-plated contacts.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 2-1877846-1

The TE Connectivity AMP Connectors 2-1877846-1 maintains Active product status with RoHS Compliant certification and unlimited moisture sensitivity rating. This part is suitable for medical applications as designated in its series classification. The operating temperature range of -50°C to 170°C provides extended thermal performance. Selection of this part is appropriate when the Medical CPC series specification is required and the latch lock fastening mechanism is specified.

Substitute Part: EN3C6MX

The Switchcraft Inc. EN3C6MX is ROHS3 Compliant with equivalent moisture sensitivity rating. This part provides higher current capacity (7.5A versus 6A) and includes integrated features such as backshell, cable clamp, and coupling nut. The EN3C6MX operates within a narrower temperature range (-40°C to 65°C) and features bayonet lock fastening instead of latch lock. The part includes IP66/IP68 ingress protection rating, providing enhanced environmental sealing.

Selection of EN3C6MX is appropriate when higher current capacity is beneficial, bayonet lock coupling is acceptable, and the narrower operating temperature range aligns with application requirements. The integrated backshell and cable clamp features provide mechanical advantages in certain installation scenarios.

Frequently Asked Questions (FAQ)

Q: Can EN3C6MX directly replace 2-1877846-1 in all applications?

A: EN3C6MX provides electrical and mechanical compatibility as a 6-position male plug connector with solder cup termination and gold-plated contacts. However, differences exist in fastening type (bayonet lock versus latch lock), operating temperature range (-40°C to 65°C versus -50°C to 170°C), and voltage rating (250VAC/DC versus 300VAC). Substitution is valid only when these parameter differences are acceptable for the specific application.

Q: What are the key differences in fastening mechanisms?

A: The 2-1877846-1 uses latch lock fastening, while the EN3C6MX uses bayonet lock fastening. Latch lock provides push-to-connect coupling, whereas bayonet lock requires rotational engagement. The choice between these mechanisms depends on the mating connector type and installation procedure requirements.

Q: Does the EN3C6MX provide better environmental protection?

A: The EN3C6MX includes IP66/IP68 ingress protection rating, indicating dust-tight and waterproof performance. The 2-1877846-1 does not specify an ingress protection rating. Applications requiring sealed connectors benefit from the EN3C6MX environmental specifications.

Q: Are both parts suitable for medical applications?

A: The 2-1877846-1 is designated for medical applications within the Medical CPC series. The EN3C6MX lists medical as one of multiple application categories alongside general purpose, instrumentation, and marine applications. Both parts maintain RoHS compliance and unlimited moisture sensitivity ratings appropriate for medical device manufacturing.

Q: What is the significance of the current rating difference?

A: The EN3C6MX provides 7.5A current capacity compared to 6A for the 2-1877846-1. This higher rating in the substitute part does not create incompatibility; it indicates the EN3C6MX can safely handle equal or greater current loads. Applications requiring exactly 6A operation function identically with either part.

Q: How do the operating temperature ranges affect substitution?

A: The 2-1877846-1 operates from -50°C to 170°C, while EN3C6MX operates from -40°C to 65°C. The substitute part has a narrower range. Substitution is valid only when the application operates within the -40°C to 65°C window. Applications requiring operation below -40°C or above 65°C require the original 2-1877846-1 part.

Q: What packaging differences exist between these parts?

A: The 2-1877846-1 is supplied in unspecified packaging with 792 pieces in stock. The EN3C6MX is supplied in bulk packaging with 2649 pieces in stock. Packaging differences do not affect electrical or mechanical compatibility; they relate only to order quantity and handling procedures.
