Keystone Electronics 1412-1 Pin Receptacle Connector Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 1412-1 is a pin receptacle connector designed for press-fit termination applications. This component accepts pin diameters ranging from 0.015" to 0.021" (0.38mm to 0.53mm) with no tail configuration and a beryllium copper contact material finished in gold. The part is actively produced and maintains full RoHS3 compliance with MSL Level 1 rating, making it suitable for standard PCB assembly environments without moisture sensitivity constraints.

Substitute parts are identified when equivalent electrical and mechanical parameters align within the specified tolerance ranges, ensuring functional interchangeability in target applications.

Key Parameters

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. 0553-1-15-15-11-27-10-0 qualifies as a substitute based on the following alignment of critical parameters:

Pin acceptance range overlap: The substitute accepts 0.015" ~ 0.020" (0.38mm ~ 0.51mm), which falls within the main part's 0.015" ~ 0.021" specification, ensuring compatibility with the lower pin diameter range.

Matching mechanical configuration: Both parts feature no tail design, press-fit termination, 0.140" overall length, and 0.055" flange diameter.

Identical contact material and finish: Beryllium copper with gold plating on both parts ensures equivalent electrical performance and corrosion resistance.

Compliance equivalence: Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming suitability for identical assembly and storage conditions.

The substitute introduces a hex termination feature and increased contact finish thickness (30.0µin versus 10.0µin), which represent enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the Keystone Electronics 1412-1 and Mill-Max Manufacturing Corp. 0553-1-15-15-11-27-10-0 maintain active production status with full ROHS3 compliance and MSL Level 1 certification. Selection between these parts depends on application-specific requirements:

The Keystone 1412-1 accommodates the full pin diameter range of 0.015" to 0.021", providing maximum flexibility for components at the upper tolerance limit.

The Mill-Max 0553-1-15-15-11-27-10-0 accepts pin diameters up to 0.020" and includes hex termination geometry, which may provide enhanced mechanical retention in specific PCB press-fit applications. The increased gold plating thickness (30.0µin) offers extended contact durability in high-cycle insertion environments.

Both parts are suitable for identical environmental and compliance requirements. Substitution is valid when pin diameter requirements do not exceed 0.020" and hex termination geometry is compatible with the target PCB design.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 0553-1-15-15-11-27-10-0 accept pins larger than 0.020"?

A: No. The Mill-Max substitute accepts pin diameters from 0.015" to 0.020" only. Applications requiring accommodation of pins up to 0.021" must use the Keystone 1412-1.

Q: What is the functional difference between standard press-fit and hex press-fit termination?

A: Hex termination provides a hexagonal contact geometry that increases mechanical engagement with the PCB pad, enhancing retention force. Standard press-fit uses a cylindrical contact. Both achieve electrical continuity through beryllium copper contact material.

Q: Are both parts suitable for the same storage and assembly conditions?

A: Yes. Both parts carry MSL Level 1 rating, indicating unlimited shelf life without moisture sensitivity constraints. Both maintain ROHS3 compliance for identical regulatory environments.

Q: Does the increased gold plating thickness on the Mill-Max part affect compatibility?

A: No. The increased contact finish thickness (30.0µin versus 10.0µin) represents an enhancement that does not compromise compatibility. It extends contact durability without altering electrical or mechanical interface specifications.

Q: What determines whether substitution is valid for a specific application?

A: Substitution validity depends on three factors: pin diameter requirements must not exceed 0.020", the PCB design must accommodate hex termination geometry, and the application environment must align with MSL Level 1 and ROHS3 compliance requirements.
