Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 31880 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is determined by the following key parameters:

• Terminal Type: Circular
• Stud/Tab Size: 4 Stud
• Wire Gauge Rating: 16-22 AWG
• Termination Method: Crimp
• Contact Material: Copper
• Contact Finish: Tin
• Insulation Material: Polyamide (PA), Nylon
• Physical Dimensions: Thickness 0.031" (0.79mm), Width 0.218" (5.54mm), Length 0.672" (17.07mm)
• Insulation Diameter: 0.105" ~ 0.140" (2.67mm ~ 3.56mm)
• Compliance: ROHS3 Compliant, MSL 1

The substitute part 2-31880-1 maintains identical specifications across all electrical and mechanical parameters. The primary distinction between the main part and substitute is the packaging format: the main part 31880 is supplied in Bulk packaging, while the substitute 2-31880-1 is supplied in Cut Tape (CT) packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the main part 31880 and substitute part 2-31880-1 are Active products manufactured by TE Connectivity AMP Connectors within the PIDG series. Both components maintain ROHS3 compliance and MSL 1 rating, indicating full regulatory alignment and unlimited moisture sensitivity tolerance.

Selection between these parts is determined by packaging requirements and inventory availability rather than electrical or mechanical performance. The main part 31880 is supplied in Bulk packaging with 1089 pieces in stock. The substitute part 2-31880-1 is supplied in Cut Tape (CT) packaging with 47648 pieces in stock.

For applications requiring automated assembly processes or tape-and-reel handling, the Cut Tape format of part 2-31880-1 is appropriate. For manual assembly or bulk component applications, the Bulk format of part 31880 is appropriate. Both parts deliver identical functional performance and meet all specified compliance requirements.

Frequently Asked Questions (FAQ)

Q: Are parts 31880 and 2-31880-1 electrically equivalent?

A: Yes. Both parts are identical in all electrical specifications including wire gauge rating (16-22 AWG), contact material (Copper), contact finish (Tin), and termination method (Crimp). They are rated for the same applications and deliver equivalent electrical performance.

Q: Are parts 31880 and 2-31880-1 mechanically equivalent?

A: Yes. Both parts share identical mechanical specifications including terminal type (Circular), stud size (4 Stud), physical dimensions (0.031" thickness, 0.218" width, 0.672" length), and insulation diameter range (0.105" ~ 0.140"). They are mechanically interchangeable in all applications.

Q: What is the difference between part 31880 and part 2-31880-1?

A: The only difference is packaging format. Part 31880 is supplied in Bulk packaging, while part 2-31880-1 is supplied in Cut Tape (CT) packaging. All component specifications, performance characteristics, and compliance certifications are identical.

Q: Which packaging format should I select?

A: Packaging selection depends on your assembly process. Bulk packaging (31880) is suitable for manual assembly and applications where components are handled individually. Cut Tape packaging (2-31880-1) is suitable for automated assembly equipment and tape-and-reel handling systems.

Q: Are both parts ROHS3 compliant?

A: Yes. Both part 31880 and part 2-31880-1 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting all specified regulatory requirements.

Q: Can I substitute part 31880 with part 2-31880-1 in my design?

A: Yes. Part 2-31880-1 is a direct substitute for part 31880. All electrical, mechanical, and compliance specifications are identical. Substitution is appropriate for any application currently using part 31880.

Q: What wire gauges are supported by these terminals?

A: Both parts support wire gauges from 16 AWG to 22 AWG, with insulation diameter tolerance of 0.105" to 0.140" (2.67mm to 3.56mm).
