Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 106773-9 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 110
• Pitch: 0.079" (2.00mm)
• Number of Rows: 5
• Termination: Press-Fit
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Current Rating: 1.5 A
• Operating Temperature Range: -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

Voltage Rating Consideration: Substitute parts rated at 750Vrms exceed the 500Vrms requirement of the original part and are electrically compatible for this application.

Mounting Type Variations: Substitute parts are grouped into two categories: Through Hole (direct equivalent) and Board Edge/Through Hole Right Angle (mechanical variation).

Connector Style Variations: The original part uses Connector Style A 22. Substitute parts include Style A 22, AB 22, and B 22 variants, which represent different contact configurations and keying arrangements.

Position Loading: All substitute parts maintain full position loading (all 110 positions loaded), matching the original specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Through-Hole Equivalents):

HM2S10PE5100N9LF and HM2S10PE5101N9LF are the closest functional equivalents to the 106773-9. Both maintain identical mounting type (Through Hole), connector style (A 22), and all critical electrical parameters. These parts are manufactured by Amphenol ICC (FCI), classified as Active products, and are RoHS Compliant. The HM2S10PE5101N9LF includes upper and lower shield features, while HM2S10PE5100N9LF does not include shielding. Selection between these two depends on electromagnetic interference requirements of the application.

Secondary Substitutes (Connector Style Variations):

HM2S70PE5100N9LF uses Connector Style B 22 with Through Hole mounting. This part is RoHS Compliant and Active. HM2S70PE5101N9LF is a 154-position variant (110 + 44 Ground positions) with upper and lower shielding and should only be selected if the application requires additional ground positions.

Mechanical Variation Substitutes (Board Edge Right Angle):

HM2R66PA5100N9LF and HM2R66PA5108N9LF employ Board Edge/Through Hole Right Angle mounting with Connector Style AB 22. These parts are suitable only for applications where right-angle board edge mounting is required. HM2R66PA5108N9LF includes upper shield features. Both are RoHS Compliant and Active.

Compliance Considerations:

All Amphenol ICC substitute parts are RoHS Compliant, whereas the original 106773-9 is RoHS non-compliant. For applications subject to RoHS regulations, any of the Amphenol ICC substitutes satisfy compliance requirements. All substitute parts are rated at 750Vrms, exceeding the original 500Vrms specification, providing enhanced voltage margin.

Frequently Asked Questions (FAQ)

Q: Can HM2S10PE5100N9LF directly replace the TE Connectivity 106773-9 in existing designs?

A: Yes. HM2S10PE5100N9LF matches all critical parameters: 110 positions, 0.079" (2.00mm) pitch, 5 rows, Through Hole mounting, Press-Fit termination, 1.5 A current rating, and -55°C to 125°C operating range. The higher voltage rating (750Vrms vs. 500Vrms) is compatible with the original application.

Q: What is the difference between HM2S10PE5100N9LF and HM2S10PE5101N9LF?

A: Both parts are identical except for shielding. HM2S10PE5101N9LF includes upper and lower shield features, while HM2S10PE5100N9LF has no shielding. Select HM2S10PE5101N9LF if the application requires electromagnetic shielding; otherwise, HM2S10PE5100N9LF is sufficient.

Q: Why do the substitute parts have higher voltage ratings (750Vrms vs. 500Vrms)?

A: The Amphenol ICC Millipacs® series connectors are designed with enhanced voltage specifications. A higher voltage rating does not negatively impact applications designed for lower voltages; it simply provides additional safety margin and is fully compatible.

Q: Can I use HM2R66PA5100N9LF as a substitute if my PCB layout requires right-angle mounting?

A: Yes, but only if your design accommodates Board Edge/Through Hole Right Angle mounting. HM2R66PA5100N9LF maintains all electrical parameters and position count but differs in mechanical orientation. Verify PCB footprint compatibility before selection.

Q: What is the significance of the HM2S70PE5101N9LF having 154 positions instead of 110?

A: HM2S70PE5101N9LF contains 110 signal positions plus 44 dedicated ground positions (154 total). This part is suitable only for applications requiring additional ground connections. For standard 110-position applications, use HM2S10PE5100N9LF, HM2S10PE5101N9LF, or HM2S70PE5100N9LF.

Q: Are all substitute parts RoHS Compliant?

A: Yes. All Amphenol ICC substitute parts listed are RoHS Compliant. The original TE Connectivity 106773-9 is RoHS non-compliant. If your application or supply chain requires RoHS compliance, any of the Amphenol ICC substitutes satisfy this requirement.

Q: What does "Connector Style" mean, and does it affect substitution?

A: Connector Style (A 22, AB 22, B 22) refers to the contact configuration and keying arrangement. Different styles have different mating interfaces. Verify that the substitute part's connector style is compatible with the mating connector in your application. Style A 22 parts (HM2S10PE5100N9LF, HM2S10PE5101N9LF) are direct equivalents to the original 106773-9 (Style A 22).

Q: What is the difference between Press-Fit and other termination methods?

A: Press-Fit termination uses mechanical pressure to insert contacts into plated through-holes on the PCB, eliminating the need for soldering. All listed substitutes use Press-Fit termination, matching the original part specification.

Q: Can I mix and match different substitute parts in the same design?

A: No. All connectors in a mated pair must use compatible connector styles and contact configurations. Select a single substitute part type for your application and maintain consistency across all instances.
