TE Connectivity AMP Connectors 6437276-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 6437276-3 is a 100 position female card edge connector with dual read-out configuration, 0.100" (2.54mm) pitch, and gold-plated copper alloy contacts. This connector is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system integration requirements. The dual edge configuration with through-hole solder termination supports applications requiring high-density interconnection on printed circuit boards.

Substitute Part Grouping Explanation

Substitution of the 6437276-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Number of Positions: 100
Number of Rows: 2
Pitch: 0.100" (2.54mm)
Gender: Female
Read Out: Dual
Mounting Type: Through Hole
Termination: Solder
Contact Finish: Gold
Contact Finish Thickness: 30.0µin (0.76µm)
Moisture Sensitivity Level: 1 (Unlimited)

The substitute part AMC50DRTN-S712 from Sullins Connector Solutions satisfies all mandatory matching parameters. Variations in contact material (beryllium copper versus copper alloy), insulation material (polyphenylene sulfide versus thermoplastic glass-filled), and product status (active versus obsolete) do not preclude functional substitution when electrical and mechanical interface requirements are identical.

Engineering Selection Recommendations

The AMC50DRTN-S712 from Sullins Connector Solutions is the qualified substitute for the obsolete TE Connectivity AMP Connectors 6437276-3. Selection of this substitute is supported by the following factors:

Product Status: The 6437276-3 is classified as obsolete, while the AMC50DRTN-S712 maintains active product status with confirmed inventory availability (912 pieces in stock).

Compliance and Certifications: The AMC50DRTN-S712 is ROHS3 compliant and REACH unaffected, providing regulatory compliance for applications subject to environmental and hazardous substance restrictions. The original part does not specify these compliance statuses.

Interface Compatibility: All critical electrical and mechanical parameters match exactly between the two parts, including position count, pitch, row configuration, termination method, and contact finish specifications.

Operational Specifications: The substitute part provides defined operating temperature range (-65°C ~ 150°C) and specified contact type (full bellows), offering enhanced documentation compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the AMC50DRTN-S712 be used as a direct replacement for the 6437276-3 in existing designs?

A: Yes. The AMC50DRTN-S712 matches all critical parameters: 100 positions, dual row configuration, 0.100" pitch, female gender, dual read-out, through-hole mounting, solder termination, and gold contact finish at 30.0µin thickness. The connector interfaces identically with mating components and printed circuit board layouts.

Q: What are the differences between the two parts?

A: The primary differences are contact material (beryllium copper versus copper alloy), insulation material (polyphenylene sulfide versus thermoplastic glass-filled), and product status (active versus obsolete). The substitute part also specifies operating temperature range and includes ROHS3 compliance certification. These differences do not affect mechanical or electrical interface compatibility.

Q: Why is the original part obsolete?

A: The 6437276-3 is classified as obsolete by TE Connectivity. The AMC50DRTN-S712 provides an active alternative with equivalent functionality and improved compliance documentation.

Q: What is the packaging difference?

A: The 6437276-3 packaging is not specified in available documentation. The AMC50DRTN-S712 is supplied in tray packaging, which is standard for high-volume connector applications.

Q: Are there any thermal or environmental performance differences?

A: The substitute part specifies an operating temperature range of -65°C ~ 150°C. The original part does not provide temperature specifications. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements.

Q: Is the substitute part RoHS compliant?

A: Yes. The AMC50DRTN-S712 is ROHS3 compliant and REACH unaffected. The original part does not specify compliance status.
