Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-794657-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 24
• Pitch: 0.165" (4.20mm)
• Number of Rows: 2
• Row Spacing: 0.165" (4.20mm)
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variation Parameters:

• Series designation (AMP-DUAC to VAL-U-LOK transition)
• Color (Natural to White)
• Product Status (Obsolete to Active)
• Compliance certifications (RoHS status upgrade)

The substitute parts 2-1586019-4 and 2-1586765-4 maintain full electrical and mechanical compatibility with the original 2-794657-4 while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

2-1586019-4 Selection Criteria: This substitute maintains natural color consistency with the original 2-794657-4 while providing active product status and RoHS compliance certification. The VAL-U-LOK series designation represents a product line evolution within TE Connectivity's rectangular connector portfolio. This part is suitable for applications requiring color matching to the original specification and standard RoHS compliance.

2-1586765-4 Selection Criteria: This substitute provides enhanced ROHS3 compliance certification and active product status. The white color variant differs from the original natural color specification. Selection of this part is appropriate for applications where ROHS3 compliance is mandated or where color differentiation is acceptable or beneficial for system identification purposes.

Compliance Considerations: Both substitute parts carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications as the original part, ensuring consistent export and tariff treatment. The transition from obsolete to active product status ensures long-term supply chain availability and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can 2-1586019-4 or 2-1586765-4 be used as direct replacements for 2-794657-4 in existing assemblies?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, row spacing, mounting type, termination method, and fastening mechanism. The parts are mechanically and electrically interchangeable.

Q: What is the difference between 2-1586019-4 and 2-1586765-4?

A: The primary difference is color: 2-1586019-4 is natural (matching the original 2-794657-4), while 2-1586765-4 is white. Additionally, 2-1586765-4 carries ROHS3 compliance certification compared to standard RoHS compliance on 2-1586019-4. All other electrical and mechanical parameters are identical.

Q: Why is the original 2-794657-4 marked as obsolete?

A: The 2-794657-4 belongs to the AMP-DUAC series, which has been superseded by the VAL-U-LOK series. The substitute parts 2-1586019-4 and 2-1586765-4 represent the current active product line offering equivalent functionality with enhanced compliance certifications.

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

A: The original 2-794657-4 packaging is not specified in the documentation. The substitute parts 2-1586019-4 and 2-1586765-4 are supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Do these connector housings include contacts?

A: No. All three parts (2-794657-4, 2-1586019-4, and 2-1586765-4) are housings only. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: What operating temperature range applies to these connectors?

A: The substitute parts 2-1586019-4 and 2-1586765-4 are rated for -40°C to 105°C operation. Operating temperature specification for the original 2-794657-4 is not provided in available documentation.

Q: Are these parts suitable for high-reliability applications?

A: Both substitute parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating suitability for standard industrial and commercial applications. Consult TE Connectivity technical documentation for specific high-reliability or military application requirements.
