Key Parameters

Substitute Part Grouping Explanation

Substitution of the HM2P09PCK291N9 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header, male pins with identical 77-position arrangement (55 + 22 Ground)
• Pitch & Row Configuration: 0.079" (2.00mm) pitch with 5 + 2 row layout
• Electrical Ratings: 1.5 A current rating and 750Vrms voltage rating
• Mounting & Termination: Through-hole press-fit termination with board guide feature
• Operating Temperature: -55°C ~ 125°C range
• Contact Finish: Gold plating

The substitute part HM2P09PCK291N9LF maintains identical electrical and mechanical specifications while differing in product status (active vs. obsolete) and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The HM2P09PCK291N9LF is the direct active equivalent for the obsolete HM2P09PCK291N9. Both parts share identical electrical and mechanical specifications, ensuring functional interchangeability in backplane connector applications.

The substitute part offers the following advantages:

• Active Product Status: HM2P09PCK291N9LF is currently in active production, ensuring long-term availability and supply chain continuity.
• RoHS Compliance: The substitute meets RoHS requirements, supporting compliance with environmental and regulatory standards for new designs and manufacturing processes.
• REACH Compliance: The substitute is REACH-affected, indicating full regulatory documentation and traceability for restricted substances.
• Improved Packaging: Tray packaging provides better handling and inventory management compared to bulk packaging.

For applications requiring the HM2P09PCK291N9, the HM2P09PCK291N9LF is the recommended replacement for new designs, redesigns, and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Are HM2P09PCK291N9 and HM2P09PCK291N9LF electrically and mechanically interchangeable?

A: Yes. Both parts are identical in connector type, position count, pitch, row configuration, current rating, voltage rating, operating temperature range, and contact finish. They are direct functional equivalents.

Q: Why is the main part obsolete while the substitute is active?

A: The HM2P09PCK291N9 has been discontinued by the manufacturer. The HM2P09PCK291N9LF represents the current production equivalent with updated compliance certifications (RoHS and REACH).

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

A: The main part specifies 30.0µin (0.76µm) gold plating thickness. The substitute specifies flash gold plating. Both provide gold contact finish suitable for the connector's electrical requirements.

Q: Does packaging difference affect connector performance?

A: No. Packaging (bulk vs. tray) affects handling, storage, and logistics only. Electrical and mechanical performance remain identical.

Q: Can I use HM2P09PCK291N9LF as a direct replacement in existing designs?

A: Yes. The substitute maintains identical specifications for all critical parameters: position count, pitch, row configuration, termination method, electrical ratings, and operating temperature range.

Q: Are there any compliance considerations when switching to the substitute?

A: The substitute is RoHS compliant and REACH-affected, providing better regulatory alignment for new designs and manufacturing processes. The main part is RoHS non-compliant and REACH unaffected.
