Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 312-POUCH is determined by the following critical parameters:

• Terminal Type: Twist On Wire Cap, Wing connector configuration
• Termination Method: Twist On mechanical connection
• Insulation Classification: Fully Insulated design
• Wire Material: Copper Wire Only
• Color: Yellow
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The substitute part SG-Y POUCH meets the core functional requirements of the 312-POUCH with the following consideration: the wire gauge range differs slightly (10-18 AWG versus 10-22 AWG). This represents a subset compatibility where the substitute accommodates the upper portion of the original specification range.

Parameter Comparison

Engineering Selection Recommendations

The SG-Y POUCH is the designated manufacturer substitute for the obsolete 312-POUCH. Selection of this substitute is supported by:

• Functional Equivalence: Identical terminal type, termination method, insulation classification, and wire material
• Active Product Status: The substitute is currently in active production, ensuring availability and supply chain continuity
• Regulatory Compliance: The SG-Y POUCH carries ROHS3 Compliant and REACH Unaffected certifications, meeting current environmental and regulatory requirements
• Wire Gauge Consideration: Applications utilizing wire gauges within the 10-18 AWG range are fully compatible. Applications requiring 19-22 AWG wire gauges fall outside the substitute's specification and require alternative solutions

Frequently Asked Questions (FAQ)

Q: Can the SG-Y POUCH replace the 312-POUCH in all applications?

A: The SG-Y POUCH is functionally equivalent for applications using wire gauges 10-18 AWG. Applications requiring 19-22 AWG wire gauges are not compatible with this substitute.

Q: What is the difference between the wire gauge ranges?

A: The original 312-POUCH accommodates 10-22 AWG wire, while the SG-Y POUCH accommodates 10-18 AWG wire. The substitute covers the upper portion of the original range (10-18 AWG) but does not extend to 19-22 AWG.

Q: Are there packaging differences between these parts?

A: The 312-POUCH packaging is not specified in the original documentation. The SG-Y POUCH is supplied in bulk packaging. Verify packaging requirements for your application.

Q: Does the SG-Y POUCH meet current regulatory standards?

A: Yes, the SG-Y POUCH is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements applicable to electronic components.

Q: What is the series designation for the substitute?

A: The SG-Y POUCH belongs to the Secure Grip series, representing an evolution of the original 312-POUCH design with enhanced performance characteristics.
