TE Connectivity AMP Connectors 6-1437020-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 6-1437020-1 is a 16 Position Rectangular Receptacle Connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector operates within the AMP-Latch series and features gold-plated female socket contacts rated for 28-30 AWG wire gauges. The part is currently Active in product status with 1124 pieces available in new original inventory.

Substitute parts become necessary when the primary part number reaches end-of-life status, when inventory constraints occur, or when design revisions require alternative connector configurations that maintain electrical and mechanical compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for substitution of part 6-1437020-1 are:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 16
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Gauge: 28-30 AWG
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Mounting Type: Free Hanging (In-Line)
• Series: AMP-Latch

The substitute part 2-1658526-9 meets all mandatory matching parameters. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications. The primary difference between these parts is the presence of the Feed Through feature in the main part and the RoHS compliance status, with the substitute part achieving ROHS3 Compliant certification.

Parameter Comparison

Engineering Selection Recommendations

Both part 6-1437020-1 and substitute part 2-1658526-9 are Active products from TE Connectivity AMP Connectors with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

Part 6-1437020-1 (Main Part):

• Use when Feed Through feature is required for specific application design
• RoHS non-compliant status applies to applications without RoHS regulatory requirements
• 1124 pieces currently available in inventory

Part 2-1658526-9 (Substitute):

• Use when ROHS3 Compliance is required by design specification or regulatory mandate
• REACH Unaffected status provides additional environmental compliance documentation
• 1395 pieces currently available in inventory, providing higher stock availability
• Omits Feed Through feature; verify application does not require this functionality

Both parts maintain identical contact specifications, pitch, row spacing, wire gauge compatibility, and mounting configuration. The substitute part provides enhanced compliance status without compromising electrical or mechanical performance in applications where the Feed Through feature is not essential.

Frequently Asked Questions (FAQ)

Q: Can part 2-1658526-9 be used as a direct replacement for 6-1437020-1 in all applications?

A: Part 2-1658526-9 is electrically and mechanically equivalent to 6-1437020-1 across all critical parameters including connector type, position count, pitch, row spacing, wire gauge, and contact finish. The primary difference is the absence of the Feed Through feature in the substitute part. Verify that your application does not require Feed Through functionality before substitution.

Q: What is the difference between the Feed Through feature and the Polarizing Key feature?

A: Both parts include the Polarizing Key feature, which prevents incorrect mating orientation. The Feed Through feature, present only in part 6-1437020-1, is an additional design characteristic. Consult your application schematic to determine if Feed Through is a functional requirement.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics. Select based on your regulatory and compliance requirements.

Q: Are the contact finish specifications identical between these parts?

A: Yes. Both parts feature gold contact finish at 30.0µin (0.76µm) thickness, ensuring equivalent electrical conductivity, corrosion resistance, and mating cycle durability.

Q: Can these connectors be used with different wire gauges?

A: No. Both parts are specified for 28-30 AWG ribbon cable only. Wire gauge selection is fixed by the IDC termination design and contact specifications.

Q: What is the pitch specification and why does it matter?

A: Both parts have a 0.100" (2.54mm) pitch, which defines the center-to-center spacing between contacts. This specification determines PCB layout compatibility and mating connector design. Pitch must match exactly for proper mating.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in Bulk packaging. No packaging format differences exist between the main part and substitute.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 (Unlimited) indicates that these connectors have unlimited shelf life and require no special moisture control during storage or handling. No desiccant or controlled environment storage is necessary.
