TE Connectivity 794550-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794550-8 is an 8-position rectangular connector plug housing from the AMP-DUAC series. This connector housing is designed for panel mount, snap-in applications with crimp contact termination and locking ramp fastening. The part is currently active in production with 748 pieces in stock. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design flexibility permits cross-series compatibility within equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 794550-8 are qualified based on matching the following critical parameters: connector type (plug), contact type (male pin), number of positions (8), pitch (0.165"/4.20mm), number of rows (2), row spacing (0.165"/4.20mm), mounting type (panel mount, snap-in), contact termination (crimp), fastening type (locking ramp), insulation material composition (polyamide/nylon), color (natural), and moisture sensitivity level (MSL 1). All substitute parts maintain these core electrical and mechanical specifications, ensuring functional interchangeability within applications designed for the 794550-8.

The substitute parts are distributed across two connector series: VAL-U-LOK series (TE Connectivity part numbers 1586018-8, 1969613-8, and 794953-8) and Mini-Fit Jr 5559 series (Molex part number 0039012081). These alternatives provide equivalent performance characteristics while offering different sourcing channels and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and comply with RoHS requirements, ensuring regulatory compliance for new designs and production continuity. The 794550-8 operates across a wider temperature range (-55°C to 105°C) compared to the substitute parts (-40°C to 105°C). Applications requiring the full -55°C lower temperature limit must retain the 794550-8; applications within the -40°C to 105°C range are compatible with all substitutes.

TE Connectivity VAL-U-LOK series parts (1586018-8, 1969613-8, 794953-8) provide direct manufacturer continuity and are available in higher quantities, with 1586018-8 offering the largest inventory at 4218 pieces. The Molex 0039012081 from the Mini-Fit Jr 5559 series provides cross-manufacturer compatibility with the highest inventory availability at 14087 pieces and ROHS3 compliance certification.

Insulation material specifications vary between standard polyamide (PA) and polyamide 6/6 (PA66) formulations. Both material types are functionally equivalent for the specified electrical and mechanical parameters. Selection between these alternatives depends on application-specific material requirements not defined in the core substitution parameters.

Frequently Asked Questions (FAQ)

Q: Can the 794550-8 be directly replaced with any of the substitute parts?

A: Direct replacement is possible for applications operating within the -40°C to 105°C temperature range. The 794550-8 supports extended low-temperature operation to -55°C, which the substitute parts do not. Verify your application's minimum operating temperature requirement before substitution.

Q: Are the VAL-U-LOK series parts (1586018-8, 1969613-8, 794953-8) interchangeable with each other?

A: Yes. All three VAL-U-LOK parts share identical electrical and mechanical specifications, including connector type, position count, pitch, mounting configuration, and termination method. Selection among these three is based on inventory availability and material specification preference (PA versus PA66).

Q: What is the difference between the TE Connectivity and Molex options?

A: The Molex 0039012081 is from the Mini-Fit Jr 5559 series and provides cross-manufacturer compatibility. All parts meet the same electrical and mechanical requirements. The Molex part offers the highest inventory availability (14087 pieces) and ROHS3 certification. Selection depends on supplier preference and supply chain strategy.

Q: Does the insulation material difference between PA and PA66 affect compatibility?

A: Both polyamide (PA) and polyamide 6/6 (PA66) materials meet the specified electrical and mechanical parameters for this connector housing. Material selection should be based on application-specific requirements such as chemical resistance, mechanical strength, or thermal cycling performance, which are not differentiated in the core substitution parameters.

Q: Are contacts included with these connector housings?

A: No. All parts listed, including the 794550-8 and all substitutes, are connector housings only. Contacts must be sourced separately and are not included in the package.

Q: What compliance certifications apply to these parts?

A: All parts are RoHS compliant. The 794550-8, 1586018-8, and 794953-8 carry RoHS certification. The 1969613-8 and 0039012081 carry ROHS3 certification. All parts have MSL 1 (Unlimited) moisture sensitivity rating and are classified under ECCN EAR99.

Q: Can I use these parts in applications requiring the -55°C minimum temperature?

A: Only the 794550-8 supports operation to -55°C. All substitute parts are rated to -40°C minimum. For applications requiring -55°C operation, the 794550-8 must be used.
