Engineering Selection Recommendations

Primary Substitutes (TE Connectivity AMP Connectors):

The parts 1586018-4 and 1969599-4 are direct series substitutes from TE Connectivity AMP Connectors, maintaining the same manufacturer ecosystem. Both are active product status components with current manufacturing support. Part 1969599-4 carries ROHS3 Compliant certification matching the original 794598-4, while 1586018-4 carries RoHS Compliant status. Both parts feature polyamide insulation materials and operate across the -40°C to 105°C temperature range.

Secondary Substitutes (Molex):

Parts 0039012046, 0469930410, and 1727670004 are parametric equivalents from Molex, representing cross-manufacturer substitution options. All three are active product status components with ROHS3 Compliant certification and REACH Unaffected status. These parts maintain identical electrical and mechanical specifications while offering alternative series options: Mini-Fit Jr 5559 (0039012046), Mini-Fit Jr 46993 (0469930410), and Mini-Fit TPA2 172767 (1727670004). All operate within the -40°C to 105°C temperature range.

Compliance Considerations:

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity level, ensuring compatibility with standard handling and storage protocols. ROHS3 compliance is maintained across all active substitutes, supporting regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the 794598-4 be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts maintain identical connector type, contact type, position count, pitch, row configuration, mounting type, termination method, and fastening type. These parameters define functional compatibility for rectangular connector plug housings.

Q: What is the significance of the color differences between substitute parts?

A: Color variations (white, natural, ivory, black) are cosmetic and do not affect electrical or mechanical function. Color selection should be based on application requirements or existing system color coding standards.

Q: Are there temperature operating range differences between the main part and substitutes?

A: The main part 794598-4 does not specify an operating temperature range in the provided data. All substitute parts operate across -40°C to 105°C. Applications requiring temperature operation confirmation should reference the specific system requirements.

Q: What is the difference between TE Connectivity AMP Connectors and Molex substitutes?

A: Both manufacturers provide parametrically equivalent parts meeting the same electrical and mechanical specifications. TE Connectivity AMP Connectors substitutes (1586018-4, 1969599-4) maintain the same manufacturer ecosystem. Molex substitutes (0039012046, 0469930410, 1727670004) represent cross-manufacturer alternatives from different connector series. Selection between manufacturers should be based on supply chain, inventory availability, and system integration requirements.

Q: Are contacts included with these connector housings?

A: No. All parts listed, including the main part 794598-4 and all substitutes, are connector housings only. Contacts must be procured separately and are not included with the housing.

Q: What is the difference between ROHS Compliant and ROHS3 Compliant status?

A: ROHS3 Compliant represents the current regulatory standard for restriction of hazardous substances. RoHS Compliant indicates compliance with earlier RoHS directives. Both certifications support regulatory requirements; ROHS3 represents the current standard.

Q: Can these connector housings be used interchangeably in existing assemblies?

A: Interchangeability is determined by mechanical fit and electrical compatibility. All listed parts maintain identical pitch (0.165"/4.20mm), row spacing (0.165"/4.20mm), mounting type (panel mount, snap-in), and fastening type (locking ramp). Physical installation compatibility should be verified against specific PCB or panel mounting hole patterns and clearance requirements in the target application.

Q: What is the Moisture Sensitivity Level (MSL) 1 rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. This classification applies to all listed parts.
