HM2R65PA5108N9 Equivalent & Substitute Parts

Part Overview

The HM2R65PA5108N9 is a 150-position (125 + 25 Ground) receptacle connector from Amphenol ICC (FCI) in the Millipacs® series, designed for backplane applications with 0.079" (2.00mm) pitch and press-fit termination. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2R65PA5108N9 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Receptacle, Female Sockets
• Pitch: 0.079" (2.00mm)
• Termination method: Press-Fit
• Mounting configuration: Through Hole, Right Angle
• Operating temperature range: -55°C ~ 125°C
• Contact finish: Gold

Position Configuration Considerations: Substitutes are grouped by position count. The main part specifies 150 positions (125 + 25 Ground). Substitutes with 125 positions or 138 positions represent functional alternatives where the application can accommodate reduced ground plane density or different ground distribution patterns.

Voltage and Current Ratings: Substitutes must maintain minimum electrical specifications of 500V and 1.5A to ensure equivalent performance in backplane applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (150-Position Configuration): HM2R65PA5108N9LF is the direct equivalent from Amphenol ICC (FCI), maintaining identical position count, pitch, and mounting specifications while offering active product status and RoHS compliance. This part is the primary choice for direct replacement in new designs or system upgrades.

17351252102 (HARTING har-bus® HM series) provides a 150-position alternative with identical connector style (AB 25), pitch, and row configuration. ROHS3 compliance and active status support modern procurement requirements.

Alternative Configurations (138-Position): 5646547-1 and 646547-1 (TE Connectivity Z-PACK series) offer 138-position configurations with reduced ground plane density (13 ground positions versus 25). Both maintain 0.079" pitch, press-fit termination, and upper shield features. 5646547-1 provides RoHS compliance; 646547-1 does not.

Reduced Position Configuration (125-Position): 17221252101 and 17351252101 (HARTING har-bus® HM series) provide 125-position receptacles without dedicated ground row. These represent functional alternatives where application requirements permit single-row ground distribution. Both are ROHS3 compliant and active products.

Frequently Asked Questions (FAQ)

Q: Can HM2R65PA5108N9LF directly replace HM2R65PA5108N9? A: Yes. HM2R65PA5108N9LF maintains identical electrical and mechanical specifications including 150-position count, 0.079" pitch, press-fit termination, and board edge mounting. The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What is the difference between 150-position and 138-position substitutes? A: The 150-position configuration includes 125 signal positions and 25 dedicated ground positions. The 138-position configuration includes 125 signal positions and 13 ground positions. Selection depends on application grounding requirements and PCB layout constraints.

Q: Are 125-position parts (17221252101, 17351252101) compatible with designs requiring 150 positions? A: No. These parts lack the dedicated ground row (5 + 1 row configuration) present in the main part. They are suitable only for applications where a single-row ground distribution is acceptable.

Q: What packaging options are available? A: HM2R65PA5108N9LF is supplied in Tray packaging. HARTING parts are available in Tube (17221252101, 17351252102) or Bulk (17351252101) packaging. TE Connectivity parts are supplied in Tube packaging.

Q: Do all substitutes meet the same voltage and current specifications? A: HM2R65PA5108N9LF exceeds the original specification at 750Vrms versus 500V. TE Connectivity parts (5646547-1, 646547-1) maintain 500Vrms and 1.5A ratings. HARTING parts do not specify voltage or current ratings in available documentation.

Q: What are the RoHS compliance differences? A: HM2R65PA5108N9 and 646547-1 are RoHS non-compliant. HM2R65PA5108N9LF and 5646547-1 are RoHS compliant. HARTING parts (17221252101, 17351252101, 17351252102) are ROHS3 compliant.
