TE Connectivity AMP Connectors 2-794598-0 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-794598-0 is a 20-position rectangular connector housing designed for plug applications with a 0.165" (4.20mm) pitch configuration. This component is classified as obsolete, indicating that direct procurement from original manufacturing sources may be limited. The connector features a two-row layout with panel mount, snap-in mounting capability and crimp contact termination using a locking ramp fastening mechanism. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this connector housing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2-794598-0 are identified based on strict parametric equivalence within the rectangular connectors category. The primary substitution criteria include connector type (plug), contact type (male pin), number of positions (20), pitch (0.165" / 4.20mm), number of rows (2), row spacing (0.165" / 4.20mm), mounting type (panel mount, snap-in), contact termination (crimp), and fastening type (locking ramp).

Two substitute parts meet these core parametric requirements:

TE Connectivity AMP Connectors 2-794953-0 and 2-1969605-0 are parametric equivalents from the VAL-U-LOK series. Both parts maintain identical electrical and mechanical specifications to the main part, including all dimensional parameters, contact configuration, and termination methodology. These parts differ from the main part in color (natural versus white) and product status (active versus obsolete), making them suitable direct replacements.

Molex 0395324021 is listed as a similar part but operates under different parametric constraints. This component is a terminal block header with 21 positions at 0.200" (5.08mm) pitch, representing a different connector category and pitch specification. This part does not meet the core substitution criteria for the 2-794598-0 and should not be considered a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes: 2-794953-0 and 2-1969605-0

Both TE Connectivity VAL-U-LOK series parts (2-794953-0 and 2-1969605-0) are recommended as direct substitutes for the obsolete 2-794598-0. These parts maintain complete parametric equivalence across all electrical and mechanical specifications. The transition from the obsolete AMP-DUAC series to the active VAL-U-LOK series provides improved supply chain availability while preserving connector functionality.

The 2-1969605-0 offers the additional advantage of ROHS3 compliance, providing enhanced environmental regulatory alignment for new designs and applications subject to current RoHS requirements. The 2-794953-0 maintains RoHS compliance with standard RoHS certification.

Both substitute parts are available in natural color rather than white. This color difference is cosmetic and does not affect electrical or mechanical performance. Applications where color specification is critical should evaluate the visual impact of this change.

Non-Equivalent Part: 0395324021

The Molex 0395324021 terminal block header does not qualify as a substitute for the 2-794598-0. This component operates under fundamentally different parametric constraints, including different connector category (terminal block versus rectangular connector), different number of positions (21 versus 20), and different pitch specification (0.200" / 5.08mm versus 0.165" / 4.20mm). Physical and electrical incompatibility with existing designs utilizing the 2-794598-0 precludes its use as a replacement.

Frequently Asked Questions (FAQ)

Q: Can the 2-794953-0 or 2-1969605-0 be used as direct replacements for the 2-794598-0 in existing applications?

A: Yes. Both parts maintain identical connector type, contact configuration, pitch, row spacing, mounting methodology, and termination specifications. The parts are mechanically and electrically interchangeable. The color difference (natural versus white) is the only visible distinction and does not affect functional performance.

Q: What is the significance of the product status change from obsolete to active?

A: The obsolete status of the 2-794598-0 indicates limited availability from original manufacturing sources. The active status of the 2-794953-0 and 2-1969605-0 ensures ongoing production, improved lead times, and sustained supply chain support for future procurement requirements.

Q: How do the RoHS compliance levels differ between the substitute parts?

A: The 2-794953-0 carries standard RoHS compliance certification. The 2-1969605-0 carries ROHS3 compliance, representing the current iteration of RoHS regulatory requirements. For applications subject to current environmental regulations, the 2-1969605-0 provides enhanced compliance alignment.

Q: Why is the Molex 0395324021 listed but not recommended as a substitute?

A: The 0395324021 operates under different parametric specifications, including different connector category, pitch (0.200" versus 0.165"), and position count (21 versus 20). These differences result in physical and electrical incompatibility with applications designed for the 2-794598-0. This part is not a functional equivalent.

Q: Are contacts included with the substitute parts?

A: No. Both substitute parts are connector housings only. Contacts are not included and must be sourced separately, consistent with the main part specification.

Q: What packaging options are available for the substitute parts?

A: The 2-794953-0 and 2-1969605-0 are supplied in bulk packaging. Packaging specifications should be confirmed with procurement requirements for specific applications.
