Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P09PM5111GF is determined by strict alignment of the following electrical and mechanical parameters:

• Connector type, style, and position count (77 positions with 55 + 22 Ground configuration)
• Pitch specification (0.079" / 2.00mm)
• Row configuration (5 + 2)
• Mounting method (Through Hole)
• Termination technology (Press-Fit)
• Current and voltage ratings (1.5A minimum, 500V minimum)
• Operating temperature range (-55°C ~ 125°C)
• Contact material and finish (Gold)

The substitute part HM2P09PM5111GFLF meets all these criteria and is derived from the same base product number (HM2P09), confirming functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The HM2P09PM5111GFLF is the direct active equivalent for the obsolete HM2P09PM5111GF. Both parts share identical electrical and mechanical specifications with the following distinctions:

The substitute part offers improved regulatory compliance, meeting RoHS requirements where the original does not. The voltage rating of the substitute (750Vrms) exceeds the original specification (500V), providing additional design margin. Contact finish thickness differs (Flash versus 30.0µin), though both maintain gold plating for equivalent electrical performance.

The substitute part is available in active production status with higher inventory levels, ensuring supply chain continuity for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can HM2P09PM5111GFLF be used as a direct replacement for HM2P09PM5111GF?

A: Yes. Both parts are identical in connector type, position count, pitch, row configuration, mounting method, termination technology, current rating, and operating temperature range. The substitute meets or exceeds all electrical specifications of the original.

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

A: The original part specifies 30.0µin (0.76µm) gold plating thickness. The substitute uses flash gold plating. Both provide equivalent electrical conductivity and corrosion resistance for the specified application.

Q: Does the higher voltage rating of the substitute affect compatibility?

A: No. The substitute's 750Vrms rating exceeds the original 500V specification, providing additional safety margin. This does not affect mechanical or electrical compatibility in applications designed for the original part.

Q: What packaging differences exist between these parts?

A: The original part packaging is unspecified. The substitute is supplied in Tray packaging. This affects handling and storage procedures but does not impact connector performance or compatibility.

Q: Is the RoHS compliance difference significant for substitution?

A: RoHS compliance status reflects manufacturing process and material composition. The substitute's RoHS compliance may be required for certain end-market applications or regulatory jurisdictions. Verify compliance requirements for your specific application.
