Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 61891-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal Type: Male, Pin (Plug)
• Wire Gauge: 14-18 AWG
• Barrel Diameter: 0.156" (3.96mm)
• Overall Length: 0.710" (18.03mm)
• Barrel Length: 0.350" (8.89mm)
• Termination Method: Crimp
• Contact Material: Brass
• Insulation Configuration: Non-Insulated
• Series Compatibility: Shur-Plug
• RoHS Compliance: ROHS3 Compliant

The substitute part 60766-2 maintains full dimensional and functional equivalence across all critical parameters. Variations in contact finish (Tin applied to 60766-2 versus unspecified finish on 61891-2) and insulation diameter range represent secondary characteristics that do not affect mechanical or electrical interchangeability within the specified wire gauge range.

Parameter Comparison

Engineering Selection Recommendations

The 60766-2 serves as the direct active equivalent for the obsolete 61891-2. Both components are manufactured by TE Connectivity AMP Connectors within the Shur-Plug series and maintain identical dimensional specifications, wire gauge ratings, and termination characteristics.

Compliance and Certification Alignment: Both parts achieve ROHS3 compliance and carry MSL Rating 1 (Unlimited moisture sensitivity level), indicating equivalent environmental performance and handling requirements. The 60766-2 carries REACH Unaffected status, confirming regulatory compliance for European markets.

Procurement Advantage: The 60766-2 is currently in active production status with 2343 pieces available in inventory, compared to the obsolete status of 61891-2. This ensures long-term supply chain continuity and eliminates obsolescence risk for new designs and production requirements.

Contact Finish Consideration: The tin contact finish applied to 60766-2 provides enhanced corrosion resistance compared to the unspecified finish of 61891-2, representing a technical improvement without introducing compatibility concerns for standard crimp termination applications.

Frequently Asked Questions (FAQ)

Q: Can 60766-2 be used as a direct replacement for 61891-2 in existing assemblies?

A: Yes. The 60766-2 maintains identical dimensional specifications, wire gauge compatibility, barrel diameter, and overall length. Both components feature identical termination methods (crimp), contact material (brass), and insulation configuration (non-insulated). Mechanical and electrical interchangeability is confirmed across all critical parameters.

Q: What is the significance of the tin contact finish on 60766-2?

A: The tin finish on 60766-2 provides enhanced corrosion resistance during storage and field deployment. This represents a material improvement over the unspecified finish of the obsolete 61891-2 and does not affect crimp termination compatibility or electrical performance within the specified 14-18 AWG wire gauge range.

Q: Are there packaging differences between 61891-2 and 60766-2?

A: The 61891-2 packaging specification is not provided in available documentation. The 60766-2 is supplied in Cut Tape (CT) packaging format, which is standard for terminal connector distribution and is compatible with automated assembly processes.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both 61891-2 and 60766-2 are ROHS3 compliant and carry MSL Rating 1 (Unlimited). The 60766-2 additionally carries REACH Unaffected status, confirming compliance with European chemical regulations. Both parts are classified under ECCN EAR99 and HTSUS 8536.90.4000.

Q: What is the insulation diameter range difference between the two parts?

A: The 61891-2 accommodates insulation diameters from 0.085" to 0.210" (2.16mm to 5.33mm), while the 60766-2 range is 0.085" to 0.125" (2.16mm to 3.18mm). The 60766-2 range is more restrictive but fully covers standard wire insulation diameters for 14-18 AWG conductors. Applications requiring insulation diameters exceeding 0.125" must reference the original 61891-2 specifications or identify alternative components.

Q: Why is 61891-2 listed as obsolete?

A: The 61891-2 has been discontinued by TE Connectivity AMP Connectors. The 60766-2 represents the active production equivalent and is the recommended component for all new designs and procurement requirements.
