HM2P89PDC145N9LF Equivalent & Substitute Parts

Part Overview

The HM2P89PDC145N9LF is a 110-position header connector manufactured by Amphenol ICC (FCI) from the Millipacs® series. This through-hole, press-fit connector features 88 signal positions plus 22 ground positions with 0.079" (2.00mm) pitch and is designed for backplane applications. The part is currently active in production with full inventory availability. Substitute parts may be required due to supply constraints, packaging preferences, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P89PDC145N9LF is determined by the following critical parameters:

• Connector type and gender (Header, Male Pins)
• Pitch specification (0.079" / 2.00mm)
• Mounting method (Through Hole)
• Termination technology (Press-Fit)
• Electrical ratings (1.5 A current, 750Vrms voltage)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish and thickness (Gold, 30.0µin minimum)
• Compliance certifications (RoHS, ECCN EAR99)

The substitute part 5646457-1 qualifies as an equivalent based on these parameters. However, the position count differs: the main part provides 110 positions (88 signal + 22 ground) while the substitute provides 88 positions (signal only). This difference must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the HM2P89PDC145N9LF and 5646457-1 meet identical electrical and thermal specifications, with full RoHS compliance and EAR99 classification. Selection between these parts depends on application-specific requirements:

The HM2P89PDC145N9LF provides 110 total positions with dedicated ground pins (22 ground + 88 signal), suitable for applications requiring integrated ground distribution across 10 rows (8 signal + 2 ground).

The 5646457-1 provides 88 positions across 8 rows without dedicated ground rows, appropriate for applications where ground distribution is managed separately or where the reduced position count meets functional requirements.

Both parts maintain identical current and voltage ratings, operating temperature range, and contact finish specifications. Packaging differs (Tray versus Tube), which may influence logistics and handling procedures but does not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can 5646457-1 directly replace HM2P89PDC145N9LF in all applications?

A: Direct replacement is possible only if the application does not require the 22 dedicated ground positions provided by the main part. The substitute provides 88 positions versus 110, representing a 20% reduction in total position count. Verify that your PCB layout and connector footprint accommodate the 8-row configuration of the substitute.

Q: What is the significance of the position count difference?

A: The HM2P89PDC145N9LF includes 22 dedicated ground positions distributed across 2 additional rows, providing integrated ground plane connectivity. The 5646457-1 contains only signal positions. Applications requiring distributed ground connections must use the main part or implement alternative grounding methods with the substitute.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts specify 1.5 A current rating, 750Vrms voltage rating, and -55°C to 125°C operating temperature range. Contact finish (gold, 30.0µin minimum) and termination method (press-fit) are identical.

Q: Does packaging affect electrical performance?

A: No. The main part ships in Tray packaging while the substitute ships in Tube packaging. This difference affects only storage, handling, and logistics procedures, not electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both HM2P89PDC145N9LF and 5646457-1 are RoHS compliant with EAR99 export classification.
