Key Parameters

Substitute Part Grouping Explanation

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

Electrical Compatibility Parameters:

• Number of positions (6 required)
• Termination method (solder cup required)
• Contact material and finish (copper alloy with gold plating)
• Current and voltage ratings (minimum 6A at 300VAC)

Mechanical Compatibility Parameters:

• Connector type classification (plug with male pins)
• Mounting configuration (free hanging, in-line)
• Shell material (thermoplastic construction)
• Cable opening dimensions (4.00mm to 5.20mm nominal range)

Environmental & Compliance Parameters:

• Operating temperature range (must support -50°C to 170°C minimum)
• RoHS compliance status
• Moisture sensitivity level (MSL 1 - Unlimited)

The substitute parts identified (EN3C6MX and EN3L6MX) share the core electrical and mechanical characteristics required for functional equivalence. However, specific differences in fastening type, orientation, ingress protection rating, and operating temperature range exist and must be evaluated for application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: TE Connectivity 1877846-5

The TE Connectivity 1877846-5 maintains active product status with established RoHS compliance and unlimited moisture sensitivity rating. This connector is optimized for medical applications with an extended operating temperature range of -50°C to 170°C and rated for 300VAC operation. The latch lock fastening mechanism and 80° orientation provide specific mechanical characteristics suited to medical device integration.

Substitute Option: Switchcraft EN3C6MX

The EN3C6MX is a plug connector with male pins and solder cup termination, maintaining functional equivalence in core electrical parameters. This substitute carries ROHS3 compliance and provides enhanced ingress protection (IP66/IP68). The EN3C6MX features a bayonet lock fastening mechanism and keyed orientation, which differ from the primary part. The operating temperature range (-40°C to 65°C) is narrower than the primary part, and the voltage rating is 250VAC/DC compared to 300VAC. Current rating is 7.5A, exceeding the primary part specification of 6A.

Substitute Option: Switchcraft EN3L6MX

The EN3L6MX is a receptacle connector with male pins and solder cup termination. This part shares electrical and mechanical characteristics with the EN3C6MX but differs in connector type classification. The receptacle configuration makes this substitute applicable only in applications where a receptacle interface is required. Operating temperature range, voltage rating, and current rating specifications are identical to the EN3C6MX.

Selection Criteria:

• Use the primary part (1877846-5) when medical application requirements demand the extended temperature range (-50°C to 170°C) and 300VAC rating.
• Use EN3C6MX when plug connector functionality is required and operating conditions fall within -40°C to 65°C and 250VAC/DC limits, with the understanding that bayonet lock and keyed orientation differ from the primary part.
• Use EN3L6MX only when receptacle connector configuration is required for the application interface.

All substitute parts maintain RoHS compliance, unlimited moisture sensitivity rating, and identical ECCN/HTSUS classifications as the primary part.

Frequently Asked Questions (FAQ)

Q: Can EN3C6MX directly replace 1877846-5 in all applications?

A: EN3C6MX shares the same connector type (plug, male pins), position count (6), termination method (solder cup), and contact material specifications. However, three critical differences exist: the fastening mechanism differs (bayonet lock versus latch lock), the operating temperature range is narrower (-40°C to 65°C versus -50°C to 170°C), and the voltage rating is lower (250VAC/DC versus 300VAC). Substitution is valid only when application requirements fall within the EN3C6MX specifications.

Q: What is the difference between EN3C6MX and EN3L6MX?

A: Both parts are manufactured by Switchcraft Inc. and share identical electrical and environmental specifications. The primary difference is connector type: EN3C6MX is a plug connector with male pins, while EN3L6MX is a receptacle connector with male pins. Selection depends on whether the application requires a plug or receptacle interface.

Q: Are the cable opening dimensions compatible between the main part and substitutes?

A: The main part 1877846-5 specifies cable opening of 0.157" to 0.205" (4.00mm to 5.20mm). Both Switchcraft substitutes specify 0.160" to 0.265" (4.06mm to 6.73mm). The Switchcraft range is wider and encompasses the primary part specification, providing compatibility for cables within the primary part's range.

Q: Do all three parts meet RoHS requirements?

A: Yes. The primary part 1877846-5 is RoHS Compliant. Both Switchcraft substitutes (EN3C6MX and EN3L6MX) are ROHS3 Compliant. All three parts meet current RoHS standards and carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications.

Q: What is the significance of the insert material difference (PPS versus Elastomer)?

A: The primary part uses Polyphenylene Sulfide (PPS) insert material, while both Switchcraft substitutes use Elastomer. This material difference affects mechanical properties and environmental resistance characteristics. The PPS material in the primary part provides higher temperature capability, supporting the extended operating range of -50°C to 170°C. The Elastomer material in substitutes supports the narrower range of -40°C to 65°C.

Q: Can EN3L6MX (receptacle) be used with 1877846-5 (plug) in a mated pair?

A: No. EN3L6MX is a receptacle connector with male pins, while 1877846-5 is a plug connector with male pins. Both connectors have male pins and cannot mate with each other. A receptacle with female pins would be required to mate with the plug connector.

Q: What is the current rating difference, and does it affect substitution?

A: The primary part 1877846-5 is rated for 6A, while both Switchcraft substitutes are rated for 7.5A. The higher current rating of the substitutes exceeds the primary part specification, making them suitable for applications requiring up to 6A. The substitutes provide additional current capacity margin.

Q: Are there packaging differences between the main part and substitutes?

A: The primary part 1877846-5 packaging is not specified in the provided data. Both Switchcraft substitutes (EN3C6MX and EN3L6MX) are supplied in bulk packaging. Inventory levels differ: 706 units for the primary part, 2649 units for EN3C6MX, and 2840 units for EN3L6MX.
