Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 737015-4 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Tab width: 0.250" (6.35mm)
• Tab thickness: 0.032" (0.81mm)
• Overall length: 0.894" (22.70mm)
• Gender: Female
• Mounting type: Free Hanging (In-Line)

Electrical Compatibility Parameters:

• Wire gauge range: 10-11.5 AWG
• Termination method: Crimp
• Insulation type: Non-Insulated
• Insulation diameter range: 0.134" ~ 0.201" (3.40mm ~ 5.10mm)

Regulatory & Environmental Parameters:

• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)
• Series: Mark I
• Base product number: 737015

The substitute part 737015-3 maintains identical specifications across all mechanical and electrical parameters while differing only in contact material composition and packaging configuration. Both parts belong to the same Mark I series and base product family.

Engineering Selection Recommendations

The 737015-3 serves as the direct functional equivalent to the obsolete 737015-4. Selection of the 737015-3 is supported by the following engineering criteria:

Product Status Consideration: The 737015-4 is classified as obsolete, while the 737015-3 maintains active product status with TE Connectivity AMP Connectors. Active status ensures continued availability, manufacturing support, and compliance with current regulatory standards.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings of 1 (Unlimited), confirming equivalent environmental and moisture handling characteristics.

Mechanical and Electrical Equivalence: All critical mechanical parameters including tab width, thickness, overall length, and mounting configuration are identical. Electrical parameters including wire gauge range, termination method, insulation type, and insulation diameter specifications are fully matched.

Material Composition Differences: The 737015-3 utilizes brass contact material with tin finish, whereas the 737015-4 specifies phosphor bronze contact material. Both materials are suitable for quick connect terminal applications within the specified wire gauge and electrical load parameters. The brass-tin combination in the 737015-3 provides equivalent electrical conductivity and corrosion resistance for the intended application.

Supply Chain Continuity: The 737015-3 is available in bulk packaging with significantly higher inventory levels (12,664 pieces) compared to the obsolete 737015-4 (668 pieces), ensuring reliable supply for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 737015-3 be used as a direct replacement for the 737015-4 in existing designs?

A: Yes. The 737015-3 maintains identical mechanical and electrical specifications across all critical parameters including tab dimensions, wire gauge compatibility, termination method, and overall length. Both parts are ROHS3 compliant with matching MSL ratings.

Q: What is the difference between the contact materials in these two parts?

A: The 737015-4 uses phosphor bronze contact material, while the 737015-3 uses brass with tin finish. Both materials provide equivalent electrical conductivity and corrosion resistance for quick connect terminal applications within the specified 10-11.5 AWG wire gauge range.

Q: Are there any compatibility issues with the packaging differences?

A: The 737015-4 packaging is not specified, while the 737015-3 is supplied in bulk packaging. Packaging differences do not affect connector functionality or mechanical compatibility. Bulk packaging of the 737015-3 provides cost efficiency for production volumes.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 737015-4 and 737015-3 are ROHS3 compliant with MSL ratings of 1 (Unlimited). Both parts carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: Why is the 737015-4 classified as obsolete?

A: The 737015-4 is obsolete due to its replacement by the 737015-3 within the TE Connectivity AMP Connectors product line. The 737015-3 provides equivalent functionality with active manufacturing status and improved supply availability.

Q: What wire gauges are compatible with these connectors?

A: Both the 737015-4 and 737015-3 are rated for 10-11.5 AWG wire gauges with insulation diameters ranging from 0.134" to 0.201" (3.40mm to 5.10mm).

Q: Are these connectors suitable for high-temperature applications?

A: The provided specifications do not include operating temperature ranges. Consult TE Connectivity AMP Connectors technical documentation for thermal performance data specific to your application requirements.
