Preci-Dip 892-70-010-20-002101 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Preci-Dip 892-70-010-20-002101 is an unshrouded rectangular connector header designed for through-hole, right-angle board-to-board applications. This 10-position, 2-row header operates at 0.100" (2.54mm) pitch and features male pin contacts with gold-plated mating surfaces. The connector is rated for 3A per contact at 150VDC and operates across -55°C to 125°C. With active product status and full RoHS3 compliance, this component is suitable for standard PCB interconnection applications requiring reliable push-pull fastening and solder termination.

Alternative equivalent parts may be required due to inventory constraints, regional availability, or specific application requirements for operating temperature ranges or contact finish specifications.

Engineering Selection Recommendations

Primary Selection: Preci-Dip 892-70-010-20-002101

The Preci-Dip 892-70-010-20-002101 is the specified component and should be used when available. It offers the widest operating temperature range (-55°C to 125°C) and is actively manufactured with 1083 units in stock.

Substitute Selection: Harwin Inc. M20-9740542

The Harwin M20-9740542 qualifies as a direct substitute based on identical mechanical and electrical parameters. Both components are ROHS3 compliant, UL94 V-0 rated, and feature identical pitch, position count, current rating, and contact configuration.

Substitution Considerations:

The Harwin M20-9740542 operates within a narrower temperature range (-40°C to 105°C) compared to the Preci-Dip component. Applications requiring operation below -40°C or above 105°C must use the Preci-Dip 892-70-010-20-002101.

The Harwin part features a cuttable header design, providing additional flexibility for custom position configurations. The contact length at mating is 0.228" (5.80mm) versus 0.276" (7.00mm) for the Preci-Dip, representing a minor dimensional variation that does not affect standard board-to-board interconnection applications.

Both components feature gold-plated mating contacts and identical post lengths (0.118"), ensuring compatible solder joint formation and electrical performance in standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M20-9740542 be used as a direct replacement for the Preci-Dip 892-70-010-20-002101 in all applications?

A: The Harwin M20-9740542 is mechanically and electrically compatible for applications operating within -40°C to 105°C. Applications requiring the extended temperature range of the Preci-Dip (-55°C to 125°C) must use the original component.

Q: What is the significance of the "cuttable" feature on the Harwin M20-9740542?

A: The cuttable design allows the header to be segmented into smaller position counts during assembly. This feature does not affect compatibility when used as a full 10-position, 2-row header.

Q: Are the contact finishes interchangeable between the two parts?

A: Both parts feature gold-plated mating contacts, which are functionally equivalent. The Preci-Dip uses gold post finish while the Harwin uses tin post finish. Both finishes are acceptable for standard solder termination and do not affect electrical performance.

Q: What is the impact of the different insulation materials?

A: The Preci-Dip uses glass-filled polyamide while the Harwin uses PA6T (polyamide 6T). Both materials meet UL94 V-0 flammability requirements and provide equivalent mechanical and electrical insulation properties for this application.

Q: Are both parts RoHS compliant?

A: Yes, both the Preci-Dip 892-70-010-20-002101 and Harwin M20-9740542 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the difference in contact length at mating, and does it affect compatibility?

A: The Preci-Dip features 0.276" (7.00mm) mating contact length while the Harwin features 0.228" (5.80mm). This variation is within acceptable tolerance for standard board-to-board interconnection and does not affect connector compatibility or performance.

Q: Can these parts be mixed in the same assembly?

A: Both parts are mechanically and electrically compatible and can be used interchangeably within the same assembly, provided the application temperature range does not exceed -40°C to 105°C.
