Equivalent & Substitute Parts for Keystone Electronics 1993-2

Part Overview

The Keystone Electronics 1993-2 is a PC pin terminal connector designed for through-hole mounting applications. This non-insulated brass terminal features a 0.018" (0.46mm) circular pin with gold plating and is configured for press-fit, square termination on 0.062" (1.57mm) board thickness. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. part number 5435-1-05-15-00-00-03-0 qualifies as a direct substitute based on the following critical parameters:

Pin diameter (0.018" / 0.46mm), mounting hole diameter (0.022" / 0.56mm), overall length (0.200" / 5.08mm), press-fit square termination, non-insulated construction, brass alloy contact material, gold plating at 10.0µin (0.25µm), and through-hole mounting configuration are functionally equivalent. Both parts maintain ROHS3 compliance, MSL rating of 1, and identical electrical and mechanical interface requirements. The substitute part is produced by an established connector manufacturer and carries active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the Keystone 1993-2 and Mill-Max 5435-1-05-15-00-00-03-0 maintain active production status and full ROHS3 compliance. Selection between these parts should be based on availability, lead time, and cost considerations. The Mill-Max part provides documented length-above-flange specification (0.140" / 3.56mm), which may be relevant for applications requiring precise dimensional control. Both parts carry identical MSL ratings and contact finish specifications, ensuring equivalent performance in moisture-sensitive environments and electrical conductivity requirements.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 5435-1-05-15-00-00-03-0 be used as a direct replacement for the Keystone 1993-2?

A: Yes. Both parts share identical pin diameter (0.018" / 0.46mm), mounting hole diameter (0.022" / 0.56mm), overall length (0.200" / 5.08mm), termination method (press-fit square), contact material (brass), contact finish (gold at 10.0µin), and mounting configuration (through-hole). Electrical and mechanical interfaces are equivalent.

Q: Are there differences in contact material between these parts?

A: The Keystone part specifies brass, while the Mill-Max part specifies brass alloy. Both materials provide equivalent electrical conductivity and are suitable for gold-plated press-fit applications. The gold plating thickness (10.0µin / 0.25µm) is identical on both parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Keystone 1993-2 and Mill-Max 5435-1-05-15-00-00-03-0 are ROHS3 compliant, carry MSL rating 1 (unlimited moisture sensitivity level), and are REACH unaffected. Regulatory and environmental requirements are equivalent.

Q: What is the significance of the length-above-flange specification?

A: The Mill-Max part documents length-above-flange as 0.140" (3.56mm). This parameter defines the exposed pin length above the mounting flange. The Keystone part does not specify this value separately. For applications requiring precise pin protrusion control, the documented Mill-Max specification provides additional design clarity.

Q: Are packaging quantities equivalent?

A: Packaging is specified as bulk for both parts. Inventory levels differ (Keystone: 927 pcs, Mill-Max: 1938 pcs), but packaging format and handling requirements are identical.
