Keystone Electronics 1439-2 Pin Receptacle Connector Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 1439-2 is a pin receptacle connector designed to accept pin diameters ranging from 0.032" to 0.046" (0.81mm to 1.17mm) with swage termination and no tail configuration. This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified when they maintain identical or compatible electrical and mechanical specifications within the accepted pin diameter range, overall length, socket depth, flange diameter, contact material, and termination method.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Keystone Electronics 1439-2 is determined by strict equivalence across the following critical parameters:

• Accepts Pin Diameter: 0.032" ~ 0.046" (0.81mm ~ 1.17mm)
• Tail Type: No Tail
• Termination Method: Swage
• Overall Length: 0.324" (8.23mm)
• Socket Depth: 0.200" (5.08mm)
• Flange Diameter: 0.125" (3.18mm)
• Contact Material: Beryllium Copper
• Contact Finish: Tin-Lead
• RoHS Compliance: ROHS3 Compliant

The Mill-Max Manufacturing Corp. part number 0344-2-19-01-34-01-10-0 meets all substitution criteria. Both components share identical pin acceptance range, mechanical envelope, contact material composition, and regulatory compliance status. Variations in mounting hole diameter (0.069" vs 0.067") and pin hole diameter specifications do not affect functional substitutability within the defined pin diameter acceptance range.

Frequently Asked Questions (FAQ)

Q: What determines if a pin receptacle connector can substitute for the Keystone 1439-2?

A: Substitution requires matching pin diameter acceptance range (0.032" ~ 0.046"), no-tail configuration, swage termination, overall length of 0.324", socket depth of 0.200", flange diameter of 0.125", beryllium copper contact material, and tin-lead finish. All these parameters must align exactly.

Q: Are the mounting hole diameter differences between the two parts significant?

A: The Keystone 1439-2 specifies a 0.069" mounting hole diameter while the Mill-Max 0344-2-19-01-34-01-10-0 specifies 0.067". These minor variations do not affect functional substitutability for pin receptacle applications within the defined pin diameter acceptance range.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the Keystone 1439-2 and Mill-Max 0344-2-19-01-34-01-10-0 are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code 8536.69.4040.

Q: What is the significance of the MSL rating for these connectors?

A: Both components carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture sensitivity concerns during storage and handling.

Q: Can the Mill-Max 0344-2-19-01-34-01-10-0 be used in all applications where the Keystone 1439-2 is specified?

A: Yes, provided the application requirements are limited to the specified pin diameter range, mechanical envelope, and electrical characteristics. Both components are functionally equivalent within these parameters.
