Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5-1735480-3 qualifies as a parametric equivalent based on the following criteria:

Critical Matching Parameters:

• Connector Type: Receptacle, Outer Shroud Contacts
• Number of Positions: 80
• Pitch: 0.031" (0.80mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 8.00µin (0.203µm)
• Mated Stacking Height: 17mm
• Height Above Board: 0.620" (15.75mm)
• Series: Free Height (FH)
• Features: Board Guide
• Category: Rectangular Connectors
• Packaging: Tube

All electrical and mechanical parameters are identical between the main part and the substitute part. The substitute maintains full compatibility with the same mating interfaces, PCB footprints, and electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the main part 1735481-3 and the substitute part 5-1735480-3 are Active products from TE Connectivity AMP Connectors with complete electrical and mechanical parameter equivalence. Selection between these parts may be based on the following factors:

Compliance Considerations: The substitute part 5-1735480-3 carries ROHS3 Compliance certification and REACH Unaffected status, providing explicit regulatory documentation. The main part 1735481-3 lists RoHS Status as Not applicable and REACH Status as Vendor Undefined. For applications requiring documented regulatory compliance, the substitute part offers clearer certification status.

Inventory Availability: Both parts are available in new original inventory. The substitute part 5-1735480-3 has 1036 pieces in stock compared to 941 pieces for the main part 1735481-3.

Functional Equivalence: All critical electrical and mechanical parameters are identical. Both parts are suitable for direct substitution in surface mount rectangular connector applications requiring 80 positions at 0.031" pitch with gold-plated contacts and board guide features.

Frequently Asked Questions (FAQ)

Q: Are the parts 1735481-3 and 5-1735480-3 electrically interchangeable?

A: Yes. Both parts are 80 Position Receptacle connectors with identical electrical specifications including contact finish (gold), contact finish thickness (8.00µin), pitch (0.031"), and number of rows (2). They are electrically interchangeable.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts have identical mechanical parameters including mounting type (Surface Mount), height above board (0.620"), mated stacking height (17mm), and board guide features. They share the same PCB footprint and can be used interchangeably.

Q: What is the difference between the two part numbers?

A: The parts are parametrically equivalent. The primary differences are the base product numbers (1735481 versus 1735480) and regulatory compliance documentation. The substitute part 5-1735480-3 carries explicit ROHS3 Compliance and REACH Unaffected certifications, while the main part lists these as Not applicable and Vendor Undefined respectively.
