Keystone Electronics 1641B Pin Receptacle Connector Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 1641B is a pin receptacle connector designed for 0.065" to 0.082" (1.65mm to 2.08mm) pin diameters with solder termination and no tail configuration. This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications requiring identical form, fit, and function characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1641B is determined by strict alignment of the following parameters: pin diameter acceptance range (0.065" ~ 0.082"), overall length (0.400"), socket depth (0.357"), flange diameter (0.143"), contact material (Beryllium Copper), contact finish (Tin-Lead), termination method (Solder), and tail configuration (No Tail). The Mill-Max Manufacturing Corp. part number 0394-0-15-01-07-01-10-0 meets all these criteria and is classified as a direct substitute. Both parts maintain identical pin acceptance specifications, overall dimensions, socket depth, and flange geometry. Contact material and finish specifications are equivalent, ensuring electrical performance parity. Both components carry ROHS3 compliance and unlimited moisture sensitivity ratings, confirming regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

Both the Keystone Electronics 1641B and Mill-Max Manufacturing Corp. 0394-0-15-01-07-01-10-0 are active products with ROHS3 compliance and REACH unaffected status. Selection between these components is based on availability, supply chain requirements, and manufacturing lead times. The Mill-Max part carries an operating temperature specification of -55°C to 125°C, whereas the Keystone part does not provide this parameter in the available data. Both components are certified to identical regulatory standards and carry equivalent moisture sensitivity ratings. The mounting hole diameter differs by 0.002" (0.05mm), which falls within typical manufacturing tolerances for connector applications and does not affect functional substitution.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 0394-0-15-01-07-01-10-0 directly replace the Keystone 1641B?

A: Yes. Both components accept identical pin diameters (0.065" ~ 0.082"), maintain equivalent overall length (0.400"), socket depth (0.357"), and flange diameter (0.143"). Contact material, finish, and termination specifications are identical. Both carry ROHS3 compliance and unlimited moisture sensitivity ratings.

Q: What is the significance of the mounting hole diameter difference?

A: The Keystone 1641B specifies 0.122" (3.10mm) mounting hole diameter, while the Mill-Max equivalent specifies 0.120" (3.05mm). This 0.002" (0.05mm) variance is within standard manufacturing tolerances and does not prevent functional substitution in typical PCB mounting applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes. Moisture sensitivity levels are equivalent at MSL 1 (Unlimited).

Q: What determines substitution eligibility for this connector type?

A: Substitution is determined by alignment of pin diameter acceptance range, overall length, socket depth, flange diameter, contact material, contact finish, termination method, and tail configuration. All these parameters must match the original specification for direct replacement.

Q: Does the Mill-Max part provide additional technical specifications?

A: The Mill-Max 0394-0-15-01-07-01-10-0 includes an operating temperature range of -55°C to 125°C. This specification is not provided for the Keystone 1641B in the available data. Both parts are otherwise equivalent in all documented parameters.
