Key Parameters

Substitute Part Grouping Explanation

The Molex 0010321021 qualifies as a direct substitute for the 0010311028 based on the following alignment of critical parameters:

Matching Parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (2 positions, 1 row)
• Board-to-cable/wire application style
• Shrouding design (Shrouded - 1 Wall)
• Through-hole mounting and solder termination
• Friction lock fastening mechanism
• Contact geometry and material (Square, Brass)
• Insulation composition (Polyamide PA66, Nylon 6/6)
• Flammability rating (UL94 V-2)
• Regulatory compliance (ROHS3, REACH Unaffected)
• Moisture sensitivity classification (MSL 1)

Distinguishing Feature: The substitute part specifies a pitch of 0.200" (5.08mm), whereas the main part does not list this parameter. This pitch specification in the substitute represents the standard mating distance for this connector series and does not prevent functional substitution in applications designed for this connector family.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0010321021 is the designated substitute for the obsolete 0010311028. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 0010311028 carries obsolete status, whereas the substitute 0010321021 maintains active product status with confirmed inventory availability (43,629 pieces). This transition ensures long-term supply chain continuity and manufacturing support.

Regulatory Compliance: Both parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 export classification. Flammability rating (UL94 V-2) and moisture sensitivity level (MSL 1) are equivalent across both parts.

Physical and Electrical Compatibility: All dimensional parameters, contact specifications, and material compositions are identical. The substitute part operates within the same application envelope as the original part for automotive, general purpose, industrial, medical, and telecommunications applications.

Series Designation: The main part belongs to the SPOX 5289 series, while the substitute belongs to the SPOX 5281 series. Both series employ identical connector architecture and mating characteristics within the Molex SPOX connector family.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0010321021 be used as a direct replacement for the 0010311028 in existing designs?

A: Yes. The substitute part maintains identical connector type, contact configuration, mounting method, and physical dimensions. All electrical and mechanical parameters required for board-to-cable/wire applications are equivalent.

Q: What is the significance of the pitch specification (0.200" / 5.08mm) listed for the substitute part?

A: The pitch specification defines the center-to-center distance between mating positions. This parameter is standard for the SPOX 5281 series and represents the mating distance for this connector family. The absence of this specification in the main part documentation does not indicate a difference in actual pitch; it reflects documentation variation between series designations.

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

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and UL94 V-2 flammability rating. Moisture sensitivity level (MSL 1) and export classification (EAR99) are equivalent.

Q: What packaging format is available for the substitute part?

A: The substitute part 0010321021 is supplied in bulk packaging with 43,629 pieces currently in stock.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts use brass contact material with tin plating. Contact finish thickness is 200.0µin (5.08µm) for both mating and post surfaces on both parts.

Q: Can the substitute part be used in automotive, medical, and telecommunications applications?

A: Yes. The substitute part is rated for identical applications: automotive, general purpose, industrial, medical, and telecommunications.
