Substitute Part Grouping Explanation

The substitute part 5-87579-3 is classified as a direct equivalent to the main part 87579-3 based on strict electrical and mechanical parameter alignment. Both components share identical specifications across all critical substitution criteria: connector type, contact type, position count, row configuration, mating pitch, row spacing, mounting orientation, shrouding design, termination method, contact dimensions, insulation geometry, contact material, insulation material, operating temperature range, current rating, flammability rating, and fastening mechanism.

The primary distinction between these parts is product status and packaging configuration. The main part 87579-3 carries an obsolete designation, while the substitute 5-87579-3 maintains active product status. Additionally, the substitute part is supplied in tray packaging, whereas the main part packaging specification is not provided. The contact finish specification differs between the two parts: the main part features Tin-Lead plating on both mating and post contacts, while the substitute part specifies Tin plating. Both finishes maintain identical thickness specifications of 100.0µin (2.54µm).

Substitution is permissible based on the following key parameters remaining constant:

• Connector type, contact type, and position configuration
• Mating pitch and row spacing
• Mounting type and orientation
• Shrouding and fastening design
• Contact and insulation material composition
• Operating temperature range and current rating
• Physical dimensions of all contact and insulation elements

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-87579-3 is the direct equivalent for the obsolete 87579-3 connector header. Selection of the substitute part is appropriate for all new designs and production applications requiring a 12-position, 2-row, 0.100" pitch rectangular connector header with right-angle through-hole mounting.

The substitute part 5-87579-3 provides the following advantages over the main part:

Product Status: The substitute maintains active product status, ensuring ongoing availability and manufacturer support. The main part's obsolete designation limits future procurement options and technical support.

Regulatory Compliance: The substitute part is RoHS compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution. The main part carries non-compliant status. Additionally, the substitute specifies REACH Unaffected status, providing clear regulatory definition compared to the main part's undefined REACH status.

Contact Finish Specification: The substitute part specifies Tin plating on both mating and post contacts, replacing the Tin-Lead finish of the main part. Both finishes maintain identical thickness specifications and are compatible with standard solder assembly processes. The Tin finish aligns with contemporary lead-free manufacturing practices.

All electrical and mechanical parameters remain identical between the two parts, ensuring direct functional equivalence. The connector maintains the same 3A current rating, -65°C to 105°C operating temperature range, UL94 V-0 flammability rating, and all dimensional specifications across contact geometry and insulation structure.

Frequently Asked Questions (FAQ)

Q: Can the 5-87579-3 substitute directly replace the 87579-3 in existing applications?

A: Yes. The substitute part 5-87579-3 is electrically and mechanically identical to the main part 87579-3 across all critical parameters. Both connectors feature identical position count, pitch spacing, mounting orientation, contact dimensions, and current rating. Direct replacement is permissible without circuit or mechanical redesign.

Q: What is the significance of the contact finish difference between the two parts?

A: The main part 87579-3 specifies Tin-Lead contact finish, while the substitute 5-87579-3 specifies Tin finish. Both finishes maintain identical thickness of 100.0µin (2.54µm) and are compatible with standard solder assembly processes. The Tin finish of the substitute part aligns with lead-free manufacturing standards and contemporary environmental regulations.

Q: Why is the main part 87579-3 classified as obsolete?

A: The obsolete designation indicates that the main part is no longer in active production. The substitute part 5-87579-3 maintains active product status and serves as the current production equivalent. For new designs and ongoing procurement, the substitute part should be specified.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The substitute part 5-87579-3 is RoHS compliant. The main part 87579-3 is RoHS non-compliant. Applications requiring RoHS compliance must specify the substitute part.

Q: Are there packaging differences between the two parts?

A: The substitute part 5-87579-3 is supplied in tray packaging. The main part 87579-3 packaging specification is not provided in the available documentation. Packaging configuration does not affect electrical or mechanical compatibility.

Q: What is the REACH status of these connectors?

A: The substitute part 5-87579-3 specifies REACH Unaffected status, indicating compliance with REACH regulations. The main part 87579-3 carries undefined REACH status. For applications requiring defined REACH compliance documentation, the substitute part is the appropriate selection.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the main part 87579-3 and substitute part 5-87579-3 operate across the identical temperature range of -65°C to 105°C. Operating temperature specifications do not differentiate these components.

Q: What is the current rating for these connector headers?

A: Both the main part 87579-3 and substitute part 5-87579-3 are rated for 3A continuous current. Current handling capacity is identical between the two parts.

Q: Can these connectors be used for board-to-board and cable applications?

A: Yes. Both the main part 87579-3 and substitute part 5-87579-3 are classified as board-to-board or cable style connectors. The right-angle mounting orientation and shrouded 4-wall design accommodate both application types.
