Keystone Electronics 3502 Pin Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 3502 is a pin receptacle connector designed to accept pin diameters of 0.015" to 0.025" (0.38mm to 0.64mm) with standard tail press-fit termination. This component is classified as an active product with full 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 where the connector footprint and functional requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. part number 1030-3-17-15-30-27-02-0 qualifies as a substitute for the Keystone Electronics 3502 based on the following critical parameters:

• Accepts identical pin diameter range: 0.015" ~ 0.025" (0.38mm ~ 0.64mm)
• Press-fit termination maintained
• Mounting hole diameter: 0.057" (1.45mm) — identical
• Flange diameter: 0.072" (1.83mm) — identical
• Tail diameter: 0.025" (0.64mm) square — identical
• Gold contact finish applied
• RoHS3 compliant
• MSL rating: 1 (Unlimited)

The primary difference is the tail type configuration: the 3502 features a standard tail, while the 1030-3-17-15-30-27-02-0 features a wire wrap tail. This distinction affects board-level integration method but does not alter the core receptacle acceptance criteria or electrical interface.

Parameter Comparison

Engineering Selection Recommendations

Both the Keystone Electronics 3502 and Mill-Max Manufacturing Corp. 1030-3-17-15-30-27-02-0 maintain active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts depends on termination method requirements: the 3502 is specified for standard press-fit applications, while the 1030-3-17-15-30-27-02-0 accommodates wire wrap termination. The contact finish thickness difference (10.0µin versus 30.0µin) reflects manufacturing process variation and does not affect functional compatibility for the specified pin diameter acceptance range. Both parts carry MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 1030-3-17-15-30-27-02-0 directly replace the Keystone 3502 in existing designs?

A: Direct replacement is possible only if the board design accommodates wire wrap termination. The pin acceptance criteria, mounting hole diameter, and flange diameter are identical. If the original design requires standard press-fit tail configuration, the 3502 must be retained.

Q: What is the significance of the contact material difference between beryllium copper and brass alloy?

A: Both materials provide adequate electrical conductivity and mechanical retention for the specified pin diameter range. The material difference reflects manufacturer design choice and does not alter the functional interface for pin acceptance or press-fit performance.

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

A: Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 rating. No compliance barriers exist for substitution from a regulatory standpoint.

Q: How do the socket depth measurements affect compatibility?

A: The socket depth difference of 0.002" (0.06mm) between the 3502 (0.160") and 1030-3-17-15-30-27-02-0 (0.162") is within typical manufacturing tolerance and does not affect pin insertion or retention for the specified pin diameter range.

Q: What inventory considerations apply to these parts?

A: The Keystone 3502 has 1112 pieces in stock, while the Mill-Max 1030-3-17-15-30-27-02-0 has 1310 pieces available. Availability should be evaluated against project lead time requirements and termination method compatibility.
