Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 171506-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Wire gauge range: 18-22 AWG
• Contact material: Copper
• Contact finish: Tin
• Termination method: Crimp

Mechanical Compatibility Parameters:

• Terminal type: Circular
• Stud size: 8 Stud
• Mounting configuration: Free Hanging (In-Line)
• Insulation type: Insulated
• Color: Red
• Serrated termination feature

Series Compatibility:

• PIDG series designation

The substitute part 171506-1 maintains all critical electrical and mechanical parameters required for direct substitution. Both parts share the same base product number (171506) and differ only in packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 171506-1

The 171506-1 is the direct functional equivalent of the 171506-3. Both components are manufactured by TE Connectivity within the PIDG series and share identical electrical and mechanical specifications. The 171506-1 is currently in active production status with significantly higher inventory availability (6,838 pieces in stock versus 743 pieces for the obsolete 171506-3).

Compliance and Certification:

The 171506-1 carries RoHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and system updates. Both parts maintain identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), ECCN classification (EAR99), and HTSUS codes (8536.90.4000).

Packaging Consideration:

The 171506-1 is supplied in bulk packaging, which may differ from the original packaging of the 171506-3. This distinction affects procurement and inventory management but does not impact component performance or compatibility.

Insulation Diameter Variance:

The insulation diameter specification differs slightly between the two parts. The 171506-3 specifies 0.105" to 0.140" (2.67mm to 3.56mm), while the 171506-1 specifies 0.080" to 0.125" (2.03mm to 3.18mm). Both ranges accommodate standard 18-22 AWG wire insulation dimensions and maintain functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 171506-1 be used as a direct replacement for the 171506-3?

A: Yes. The 171506-1 maintains identical electrical and mechanical specifications across all critical parameters including terminal type, stud size, wire gauge range, contact material, contact finish, and termination method. The components are functionally equivalent for circuit applications.

Q: What is the difference between the 171506-3 and 171506-1?

A: The primary differences are product status and packaging. The 171506-3 is obsolete, while the 171506-1 is in active production. The 171506-1 is supplied in bulk packaging and carries RoHS3 compliance certification. The insulation diameter tolerance ranges differ slightly but both accommodate standard 18-22 AWG wire.

Q: Why is the 171506-3 listed as obsolete?

A: The 171506-3 has been discontinued by TE Connectivity. The 171506-1 serves as the active production equivalent and is the recommended component for new applications and replacements.

Q: Are there any compatibility concerns when substituting the 171506-1 for the 171506-3?

A: No compatibility concerns exist for electrical or mechanical function. Both components are designed for identical applications within the PIDG series. The insulation diameter tolerance ranges are slightly different but both are suitable for 18-22 AWG wire gauges.

Q: What wire gauges are compatible with these terminals?

A: Both the 171506-3 and 171506-1 are rated for 18-22 AWG wire gauges. Wire selection must fall within this range to ensure proper crimp termination and electrical contact.

Q: What is the stud size for these ring terminals?

A: Both components feature an 8 stud configuration, which accommodates standard #8 fasteners and connection points.

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

A: The provided specifications do not include temperature rating data. Consult TE Connectivity technical documentation for thermal performance characteristics.

Q: What is the contact material and finish?

A: Both components use copper contacts with tin plating. This combination provides corrosion resistance and reliable electrical conductivity for general-purpose circuit applications.

Q: Is RoHS compliance required for my application?

A: The 171506-1 carries RoHS3 compliance certification. If RoHS compliance is a requirement, the 171506-1 is the appropriate selection. The 171506-3 compliance status is not specified in the provided data.
