Part Overview

The TE Connectivity AMP Connectors 794542-8 is an 8-position rectangular connector plug housing with 4.20mm pitch, designed for free-hanging in-line applications. This connector belongs to the AMP-DUAC series and features crimp contact termination with locking ramp fastening. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The connector accommodates male pin contacts arranged in 2 rows with 0.165" (4.20mm) row spacing and is supplied in natural color.

Substitute Part Grouping Explanation

Substitution of the 794542-8 is determined by strict equivalence across 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 (free hanging in-line), contact termination (crimp), and fastening type (locking ramp). All substitute parts listed maintain these core electrical and mechanical specifications. Color variations and series differences do not affect functional compatibility when these parameters are identical. Moisture sensitivity level remains constant across all alternatives at MSL 1 (Unlimited).

Engineering Selection Recommendations

For applications requiring replacement of the obsolete 794542-8, the TE Connectivity AMP Connectors 1586000-8 and 1969612-8 are the primary alternatives. Both parts are active products from the VAL-U-LOK series and maintain full parametric equivalence with the original part. The 1586000-8 carries RoHS Compliant certification, while the 1969612-8 carries ROHS3 Compliant certification, providing regulatory compliance options for different application requirements.

The Molex 0039013083 from the Mini-Fit Jr 5559 series is a cross-manufacturer equivalent with identical electrical and mechanical specifications. This part is active and ROHS3 Compliant, offering an alternative sourcing option from a different manufacturer.

The TE Connectivity AMP Connectors 2029027-8 is functionally equivalent but differs in color (black versus natural). This part is obsolete and should be considered only when color specification is a secondary requirement and active alternatives are unavailable.

Frequently Asked Questions (FAQ)

Q: Can the 1586000-8 directly replace the 794542-8 in existing assemblies?

A: Yes. The 1586000-8 maintains identical specifications across all critical parameters: 8 positions, 0.165" (4.20mm) pitch, 2-row configuration with 0.165" (4.20mm) row spacing, crimp termination, and locking ramp fastening. Both are natural color plugs with free-hanging in-line mounting.

Q: What is the difference between the 1969612-8 and 1586000-8?

A: Both parts are parametrically equivalent with identical connector specifications. The primary difference is the insulation material composition: 1969612-8 uses Polyamide (PA66) Nylon 6/6, while 1586000-8 uses Polyamide (PA) Nylon. Both support operating temperatures of -40°C to 105°C and carry MSL 1 (Unlimited) rating.

Q: Why is the 2029027-8 listed as a substitute if it is black instead of natural?

A: The 2029027-8 is functionally equivalent across all electrical and mechanical parameters. Color is a cosmetic attribute that does not affect connector performance or compatibility. This part is included as a substitute option when color specification is not a design constraint.

Q: Is the Molex 0039013083 compatible with TE Connectivity connector systems?

A: The 0039013083 is parametrically equivalent to the 794542-8 across all critical specifications: connector type, contact type, position count, pitch, row configuration, mounting type, termination method, and fastening type. Cross-manufacturer compatibility depends on mating connector specifications and system design requirements.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 (Unlimited) indicates that the connector has unlimited shelf life and does not require special moisture control storage conditions. This applies uniformly across all listed substitute parts.

Q: Are all substitute parts available in bulk packaging?

A: The 794542-8 original part does not specify packaging type. The substitute parts 1586000-8, 1969612-8, 2029027-8, and 0039013083 are all supplied in bulk packaging, which is standard for rectangular connector housings.
