TE Connectivity AMP Connectors 499997-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 499997-4 is a 20 Position Rectangular Receptacle Connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable in the 26-28 AWG wire gauge range. This connector features gold-plated forked contacts and operates as a free-hanging in-line component with feed-through capability.

The 499997-4 carries an Obsolete product status, making it necessary to identify equivalent and substitute components for ongoing procurement and system maintenance. Active alternatives are available that maintain electrical and mechanical compatibility while offering improved availability and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 499997-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 20
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Gauge: 26-28 AWG
• Wire Type: Ribbon Cable
• Mounting Type: Free Hanging (In-Line)
• Features: Feed Through

Acceptable Variations:

• Contact Type: Forked or Female Socket configurations are functionally equivalent for IDC ribbon cable termination
• Manufacturer: Different manufacturers (TE Connectivity, 3M) produce compatible rectangular connectors within the AMP-Latch and 3000 series families
• Packaging: Tube or Bulk packaging does not affect electrical or mechanical compatibility
• Color: Cosmetic variation does not impact function
• Contact Finish Thickness: Variations in gold plating thickness (15.0µin to 30.0µin) remain within acceptable contact durability ranges
• Product Status: Active status is preferred over Obsolete for long-term availability

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 1658620-4

The 1658620-4 is the direct equivalent to the 499997-4. Both components share identical electrical and mechanical specifications within the AMP-Latch series. The 1658620-4 offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance addresses regulatory requirements for new designs and procurement
• Identical contact geometry, pitch, and termination method guarantee mechanical and electrical interchangeability
• Higher inventory availability (3194 units) compared to the obsolete 499997-4
• Tube packaging provides organized component handling

Secondary Substitute: 3M 3421-6020

The 3421-6020 provides functional equivalence with the following considerations:

• Active product status and RoHS compliance support modern procurement standards
• Identical electrical specifications across all critical parameters (pitch, positions, rows, wire gauge, termination method)
• Female Socket contact type is functionally compatible with IDC ribbon cable termination
• Enhanced contact finish thickness (30.0µin) provides increased durability in high-cycle applications
• Strain Relief feature offers additional mechanical protection
• Different manufacturer (3M) and series (3000) require verification of mechanical fit in existing connector housings
• Gray color differs from the original black specification

Compliance Considerations:

The 499997-4 carries RoHS non-compliant status. Both substitute parts (1658620-4 and 3421-6020) meet current RoHS requirements, making them suitable for applications subject to RoHS regulations. The 1658620-4 specifically achieves ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 1658620-4 directly replace the 499997-4 in existing assemblies?

A: Yes. The 1658620-4 maintains identical specifications across all critical parameters: 20 positions, 0.100" pitch, 2-row configuration, IDC termination, 26-28 AWG ribbon cable compatibility, and free-hanging in-line mounting. Both components are within the AMP-Latch series and share the same base contact geometry.

Q: What is the difference between the forked contact type in the 499997-4 and the female socket contact type in the 3421-6020?

A: Both contact types are designed for IDC ribbon cable termination and provide equivalent electrical performance. The forked contact uses a split design to grip the ribbon conductor, while the female socket uses a socket cavity. Both achieve reliable contact with standard ribbon cable in the 26-28 AWG range. The choice between them depends on existing connector housing compatibility.

Q: Does the higher contact finish thickness in the 3421-6020 (30.0µin versus 15.0µin) affect compatibility?

A: No. Both finish thicknesses provide adequate gold plating for contact durability and electrical performance. The thicker plating in the 3421-6020 offers extended contact life in high-cycle mating applications but does not impact electrical or mechanical interchangeability.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 1658620-4 is supplied in Tube packaging, while the 3421-6020 is supplied in Bulk packaging. Packaging does not affect electrical or mechanical performance. Selection depends on inventory management and handling requirements.

Q: Why is RoHS compliance important for selecting a substitute?

A: RoHS compliance is a regulatory requirement for electronic components in many markets. The 499997-4 is RoHS non-compliant, while both substitute parts meet RoHS standards. For new designs or procurement in regulated markets, RoHS-compliant alternatives are necessary.

Q: Can the 3421-6020 be used in applications where the 499997-4 was originally specified?

A: The 3421-6020 is electrically and mechanically compatible with the 499997-4 across all critical parameters. However, verification of mechanical fit within existing connector housings is required due to the different manufacturer and series designation. The 3M 3000 series housing may have dimensional variations compared to the TE Connectivity AMP-Latch series.

Q: What is the significance of the "Feed Through" feature?

A: The Feed Through feature indicates that the connector allows ribbon cable to pass through the connector body, enabling daisy-chain or multi-point connections. All three parts (499997-4, 1658620-4, and 3421-6020) include this feature, maintaining functional equivalence.

Q: Is the color difference between the 499997-4 (black) and 3421-6020 (gray) a concern?

A: Color is a cosmetic specification and does not affect electrical or mechanical performance. The color difference reflects different manufacturer design standards but does not impact connector function or compatibility.
