Keystone Electronics 1445 Pin Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 1445 is a pin receptacle connector designed to accept pin diameters of 0.032" to 0.046" (0.81mm to 1.17mm). This component features a press-fit, knurled termination with no tail configuration and is constructed from beryllium copper with tin-lead contact finish. The part is currently active in production with 1048 pieces available in new original stock. Alternative equivalent parts may be required due to supply availability, lead time considerations, or specific design requirements for termination method or mechanical interface.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Keystone Electronics 1445 is determined by the following critical parameters:

Pin Acceptance Range: The substitute part must accept pin diameters of 0.032" to 0.046" (0.81mm to 1.17mm) to ensure mechanical compatibility with existing pin headers and connectors.

Tail Configuration: The no-tail design is essential for press-fit applications where the connector is inserted directly into a PCB without protruding leads.

Overall Length and Socket Depth: These dimensions must match or be compatible with the PCB layout and component spacing requirements. The 0.206" overall length and 0.180" socket depth define the physical envelope.

Flange Diameter: The 0.091" flange diameter establishes the mounting interface and must remain consistent for proper board-level integration.

Contact Material and Finish: Beryllium copper with tin-lead finish provides the electrical and corrosion resistance properties required for reliable signal transmission and long-term reliability.

Compliance Standards: RoHS3 compliance and MSL 1 rating ensure regulatory conformance and moisture tolerance for standard manufacturing and storage conditions.

The Mill-Max Manufacturing Corp. part 0328-0-15-01-34-01-10-0 qualifies as an equivalent substitute based on matching all critical parameters, with the exception of termination method (hex vs. knurled), which represents a mechanical interface variation rather than a functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Keystone Electronics 1445 and the Mill-Max Manufacturing Corp. 0328-0-15-01-34-01-10-0 are active production parts with full RoHS3 compliance and MSL 1 moisture sensitivity ratings. Both parts share identical pin acceptance ranges, overall dimensions, socket depth, flange diameter, contact material, and contact finish specifications.

The primary distinction between these parts is the termination interface: the Keystone 1445 uses a knurled press-fit design, while the Mill-Max 0328-0-15-01-34-01-10-0 uses a hex press-fit design. This difference affects the mechanical insertion method and tooling requirements but does not alter electrical performance or functional compatibility with standard pin headers.

The Mill-Max part provides an additional specification: an operating temperature range of -55°C to 125°C, which is not documented for the Keystone part. Both parts are suitable for standard commercial and industrial applications requiring press-fit pin receptacle connectors in the 0.032" to 0.046" pin diameter range.

Selection between these parts should be based on tooling availability for the specific termination method (knurled vs. hex), inventory requirements, and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 0328-0-15-01-34-01-10-0 be used as a direct replacement for the Keystone 1445?

A: Yes, from an electrical and mechanical standpoint. Both parts accept the same pin diameter range (0.032" to 0.046"), share identical overall length and socket depth dimensions, and use the same contact material and finish. The difference in termination method (hex vs. knurled) requires different insertion tooling but does not affect electrical performance or board-level compatibility.

Q: What is the difference between knurled and hex termination?

A: Knurled termination uses a textured cylindrical surface for press-fit insertion, while hex termination uses a six-sided geometric profile. Both are press-fit methods; the choice depends on available insertion equipment and manufacturing process requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Keystone 1445 and Mill-Max 0328-0-15-01-34-01-10-0 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What pin diameters do these connectors accept?

A: Both parts accept pin diameters ranging from 0.032" to 0.046" (0.81mm to 1.17mm). Pins outside this range will not fit properly and may damage the connector.

Q: What is the mounting hole diameter for each part?

A: The Keystone 1445 has a mounting hole diameter of 0.076" (1.93mm), while the Mill-Max 0328-0-15-01-34-01-10-0 has a mounting hole diameter of 0.079" (2.01mm). This minor difference may require PCB layout adjustment if switching between parts.

Q: Do these parts have specified operating temperature ranges?

A: The Mill-Max 0328-0-15-01-34-01-10-0 specifies an operating temperature range of -55°C to 125°C. The Keystone 1445 does not provide an operating temperature specification in the available documentation.
