S1621-06 Equivalent & Substitute Parts

Part Overview

The S1621-06 is a 2-position (1 x 2) surface mount shunt connector from Harwin Inc.'s EZ BoardWare series. This non-insulated, non-gendered jumper operates at 10A and features a 0.319" (8.10mm) pitch with tin-lead contact finish. The part is currently obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S1621-06 is based on the following critical parameters that must remain constant:

• Number of positions: 2 (1 x 2) configuration
• Pitch spacing: 0.319" (8.10mm)
• Height: 0.071" (1.80mm)
• Type: Non-insulated connector
• Current rating: 10A minimum
• Series compatibility: EZ BoardWare

The S1621-46R qualifies as a direct substitute based on matching all mechanical and electrical parameters. The primary difference is the contact finish material (tin versus tin-lead) and the active product status of the substitute, which addresses the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

The S1621-46R is the direct substitute for the obsolete S1621-06. Both parts maintain identical mechanical dimensions and electrical ratings, ensuring PCB-level compatibility without redesign.

The S1621-46R offers the advantage of active product status, ensuring continued availability and supply chain reliability. The contact finish change from tin-lead to tin reflects modern manufacturing standards and RoHS3 compliance, which the substitute achieves while the original part does not.

For applications requiring RoHS compliance or long-term component availability, the S1621-46R is the appropriate selection. The tin contact finish at 118.1µin (3.00µm) provides adequate corrosion resistance for the 10A current rating and MSL 1 moisture environment.

Frequently Asked Questions (FAQ)

Q: Can the S1621-46R be used as a direct replacement for the S1621-06 on existing PCBs?

A: Yes. Both parts share identical pitch (0.319"), height (0.071"), position count (2), and current rating (10A). No PCB modifications are required.

Q: What is the difference between the tin-lead and tin contact finishes?

A: The S1621-06 uses tin-lead (157.5µin / 4.00µm), while the S1621-46R uses tin (118.1µin / 3.00µm). Both finishes support the 10A rating. The tin finish reflects current manufacturing practices and enables RoHS3 compliance.

Q: Why is the S1621-06 listed as obsolete?

A: The S1621-06 is no longer in active production. The S1621-46R is the current production equivalent within the EZ BoardWare series.

Q: Does the packaging difference affect compatibility?

A: The S1621-46R is supplied in Cut Tape (CT) and Digi-Reel packaging formats. Packaging does not affect electrical or mechanical compatibility; it only impacts handling and assembly logistics.

Q: Is the S1621-46R RoHS compliant?

A: Yes. The S1621-46R is ROHS3 compliant, whereas the S1621-06 is RoHS non-compliant. This is relevant for applications subject to RoHS regulations.
