Keystone Electronics 1441 Pin Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 1441 is a pin receptacle connector designed to accept pin diameters of 0.032" to 0.046" (0.81mm to 1.17mm) with solder termination and no tail configuration. This connector is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Alternative equivalent parts may be required due to inventory availability, specific packaging requirements, or design optimization needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Keystone Electronics 1441 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Accepts Pin Diameter: 0.032" ~ 0.046" (0.81mm ~ 1.17mm)
• Tail Type: No Tail
• Termination: Solder
• Contact Material: Beryllium Copper
• Contact Finish: Gold
• Length - Overall: 0.221" (5.61mm)
• Socket Depth: 0.221" (5.61mm)
• Flange Diameter: 0.090" (2.29mm)

The Mill-Max Manufacturing Corp. part number 0329-0-15-15-34-27-10-0 qualifies as a direct substitute because it maintains all mandatory compatibility parameters. Variations in contact finish thickness, mounting hole diameter, and operating temperature range do not affect the core substitution relationship when the primary electrical and mechanical interfaces remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the Keystone Electronics 1441 and Mill-Max Manufacturing Corp. 0329-0-15-15-34-27-10-0 maintain active product status with full ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on:

Inventory and Packaging Availability: The Mill-Max part offers significantly higher inventory availability (43,622 pcs vs. 1,022 pcs) and is supplied in bulk packaging, making it suitable for high-volume production requirements.

Regulatory Compliance: Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes, ensuring equivalent regulatory standing.

Physical Interface Compatibility: Mounting hole diameter tolerance (0.076" vs. 0.075") represents a negligible difference of 0.001" (0.025mm) and does not affect PCB layout compatibility for standard mounting applications.

Contact Durability: The Mill-Max part provides enhanced contact finish thickness (30.0µin vs. 10.0µin), which may extend service life in high-cycle insertion applications, though both specifications meet standard connector performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 0329-0-15-15-34-27-10-0 be used as a direct replacement for the Keystone 1441?

A: Yes. Both parts accept identical pin diameters (0.032" to 0.046"), feature identical overall length and socket depth (0.221"), maintain the same flange diameter (0.090"), and use beryllium copper with gold plating. The electrical and mechanical interfaces are fully compatible.

Q: What is the significance of the contact finish thickness difference?

A: The Mill-Max part specifies 30.0µin (0.76µm) gold plating compared to the Keystone part's 10.0µin (0.25µm). Both thicknesses meet standard connector specifications. The thicker plating on the Mill-Max part provides additional corrosion resistance and may improve durability in high-insertion-cycle environments.

Q: Are there any differences in operating conditions between these parts?

A: The Mill-Max part specifies an operating temperature range of -55°C to 125°C. The Keystone part does not provide an operating temperature specification in the available data. For applications requiring confirmed temperature performance, the Mill-Max specification provides explicit thermal operating limits.

Q: Does the mounting hole diameter difference affect PCB design?

A: The mounting hole diameter difference of 0.001" (0.025mm) between the Keystone part (0.076") and Mill-Max part (0.075") is within standard PCB tolerance ranges and does not require design modification for typical through-hole mounting applications.

Q: What packaging options are available?

A: The Keystone 1441 is supplied in standard packaging (not specified). The Mill-Max 0329-0-15-15-34-27-10-0 is supplied in bulk packaging, which is suitable for automated assembly and high-volume production workflows.

Q: Are both parts RoHS compliant?

A: Yes. Both the Keystone 1441 and Mill-Max 0329-0-15-15-34-27-10-0 are ROHS3 compliant with unlimited moisture sensitivity ratings (MSL 1), meeting current environmental and regulatory requirements.
