HM2P89PDC145N9 Equivalent & Substitute Parts

Part Overview

The HM2P89PDC145N9 is a 110-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This press-fit connector features 88 signal positions plus 22 ground positions with 0.079" (2.00mm) pitch and through-hole mounting. The part is currently obsolete, making identification of suitable alternatives necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P89PDC145N9 is determined by the following critical parameters:

• Connector type (Header, Male Pins)
• Pitch (0.079" / 2.00mm)
• Mounting type (Through Hole)
• Termination method (Press-Fit)
• Current and voltage ratings (1.5 A, 750Vrms)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold)

Two substitute parts are identified:

1. HM2P89PDC145N9LF — Direct equivalent from the same manufacturer series with identical electrical and mechanical specifications. Differs only in packaging format and compliance status.

2. 5646457-1 — TE Connectivity alternative with matching core electrical parameters and press-fit termination. Position count differs (88 vs. 110), requiring application-level compatibility verification.

Parameter Comparison

Engineering Selection Recommendations

HM2P89PDC145N9LF is the primary substitute for the obsolete HM2P89PDC145N9. Both parts share identical electrical and mechanical specifications, including position count, pitch, and termination method. The HM2P89PDC145N9LF is currently active in production and meets RoHS compliance requirements, making it suitable for direct replacement in new designs and legacy system support.

5646457-1 from TE Connectivity provides an alternative from a different manufacturer with matching electrical ratings and press-fit termination. This part operates within the same current, voltage, and temperature parameters. However, the 5646457-1 features 88 positions in an 8-row configuration, compared to the 110-position (8+2 row) configuration of the primary part. Selection of this alternative requires confirmation that the reduced position count and different row arrangement are compatible with the target application's interconnect requirements.

Frequently Asked Questions (FAQ)

Q: Can HM2P89PDC145N9LF be used as a direct replacement for HM2P89PDC145N9?

A: Yes. Both parts are identical in electrical and mechanical specifications. The HM2P89PDC145N9LF differs only in packaging format (Tray vs. unspecified) and compliance status (RoHS Compliant vs. Non-compliant). The HM2P89PDC145N9LF is the recommended substitute due to its active product status.

Q: What is the key difference between HM2P89PDC145N9 and 5646457-1?

A: The primary difference is position count and row configuration. HM2P89PDC145N9 provides 110 positions across 8+2 rows, while 5646457-1 provides 88 positions across 8 rows. Both maintain identical pitch (0.079"), termination method (Press-Fit), and electrical ratings (1.5 A, 750Vrms). Substitution is valid only if the application can operate with the reduced position count.

Q: Are all three parts compatible with the same PCB footprint?

A: HM2P89PDC145N9 and HM2P89PDC145N9LF share identical footprints due to matching position count and pitch. The 5646457-1, with 88 positions instead of 110, requires a different PCB footprint and cannot be used as a direct mechanical replacement without board redesign.

Q: What compliance certifications apply to each part?

A: HM2P89PDC145N9 is RoHS non-compliant. HM2P89PDC145N9LF is RoHS compliant and REACH affected. 5646457-1 is RoHS compliant with REACH status vendor undefined. All three parts carry ECCN classification EAR99.

Q: Which substitute should be selected for new designs?

A: HM2P89PDC145N9LF is the recommended choice for new designs, as it maintains full compatibility with the original specification while offering active product status and RoHS compliance.
