Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 4-1877846-8 are identified based on strict alignment of core electrical and mechanical parameters. The following criteria determine substitution eligibility:

Primary Matching Parameters:

• Connector type classification (Plug, Male Pins)
• Position count (6 positions)
• Termination method (Solder Cup)
• Contact finish material (Gold plating)
• Copper alloy contact material composition

Electrical Compatibility Parameters:

• Current rating equal to or exceeding 6A
• Voltage rating equal to or exceeding 300VAC
• Operating temperature range encompassing or exceeding -50°C ~ 170°C

Mechanical Compatibility Parameters:

• Free hanging in-line mounting configuration
• Thermoplastic shell material
• Solder cup termination interface

The Switchcraft Inc. EN3C6MX meets the core connector classification, position count, termination type, contact finish, and contact material requirements. However, specific parameter variations exist that must be evaluated for application compatibility.

Engineering Selection Recommendations

TE Connectivity 4-1877846-8 (Primary Part)

The TE Connectivity 4-1877846-8 maintains active product status with established inventory availability. This part is RoHS Compliant and designated for medical applications within the Medical CPC series. The 300VAC voltage rating and -50°C ~ 170°C operating temperature range establish the baseline electrical and thermal performance envelope for this connector category.

Switchcraft EN3C6MX (Substitute Part)

The Switchcraft EN3C6MX is ROHS3 Compliant and REACH Unaffected, providing enhanced regulatory documentation. This part exceeds the current rating specification at 7.5A versus 6A. However, the voltage rating is specified at 250VAC/DC, which is lower than the primary part's 300VAC rating. The operating temperature range of -40°C ~ 65°C is narrower than the primary part, with a maximum temperature 105°C lower than the TE Connectivity specification.

The Switchcraft EN3C6MX exhibits mechanical differences including Bayonet Lock fastening versus Latch Lock, keyed orientation versus 80° orientation, and a larger cable opening range of 0.160" ~ 0.265" compared to 0.106" ~ 0.154". The insert material differs, specified as Elastomer for the Switchcraft part versus Polyphenylene Sulfide (PPS) for the TE Connectivity part.

Selection between these parts requires evaluation of specific application requirements regarding voltage rating, operating temperature limits, fastening mechanism compatibility, and cable diameter accommodation.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft EN3C6MX directly replace the TE Connectivity 4-1877846-8 in all applications?

A: Direct replacement requires verification of three critical parameters: voltage rating compatibility (250VAC/DC for EN3C6MX versus 300VAC for 4-1877846-8), operating temperature range (EN3C6MX maximum 65°C versus 4-1877846-8 maximum 170°C), and fastening mechanism compatibility (Bayonet Lock versus Latch Lock). Applications operating above 65°C or requiring 300VAC rating cannot use the EN3C6MX as a substitute.

Q: What are the mechanical compatibility considerations between these connectors?

A: The fastening types differ: the TE Connectivity 4-1877846-8 uses Latch Lock fastening while the Switchcraft EN3C6MX uses Bayonet Lock fastening. Orientation specifications also differ (80° versus Keyed). Cable opening ranges differ significantly (0.106" ~ 0.154" versus 0.160" ~ 0.265"), which affects cable diameter accommodation. These mechanical differences may require interface redesign or cable assembly modification.

Q: Are both parts compliant with current regulatory standards?

A: The TE Connectivity 4-1877846-8 is RoHS Compliant with Vendor Undefined REACH status. The Switchcraft EN3C6MX is ROHS3 Compliant with REACH Unaffected status, providing more complete regulatory documentation. Both parts carry Moisture Sensitivity Level 1 (Unlimited) classification.

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

A: The TE Connectivity 4-1877846-8 uses Polyphenylene Sulfide (PPS) insert material, while the Switchcraft EN3C6MX uses Elastomer insert material. These materials have different mechanical and thermal properties that affect connector durability, dimensional stability, and performance across the operating temperature range.

Q: How do the current ratings compare between these parts?

A: The Switchcraft EN3C6MX is rated at 7.5A, exceeding the TE Connectivity 4-1877846-8 rating of 6A. This higher current rating does not restrict substitution from an electrical capacity perspective but does not compensate for the lower voltage rating of the EN3C6MX.

Q: What packaging considerations apply to these parts?

A: The TE Connectivity 4-1877846-8 is available with 986 units in current inventory. The Switchcraft EN3C6MX is supplied in Bulk packaging with 2649 units in current inventory. Packaging format does not affect electrical or mechanical compatibility but may influence procurement and handling procedures.
