Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TE Connectivity 352268-1 is based on the following critical parameters that must remain constant or be enhanced:

Core Compatibility Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 110 (primary substitutes) or 154 (extended ground configuration)
• Pitch: 0.079" (2.00mm)
• Termination method: Press-Fit
• Contact finish: Gold plating
• Current rating: 1.5 A minimum
• Voltage rating: 500Vrms minimum
• Operating temperature range: -55°C ~ 125°C minimum
• Moisture sensitivity: Level 1

Mechanical Variation Parameters: Substitute parts may differ in mounting style (through-hole standard vs. board edge right-angle) and connector style designation (B 22 vs. AB 22), provided electrical and thermal specifications are maintained or exceeded.

Compliance Variations: Substitute parts may offer enhanced RoHS compliance and REACH status compared to the main part, which is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (110-Position Configuration):

HM2S70PE5100N9LF is the primary direct substitute for the TE Connectivity 352268-1. Both connectors share identical mounting style (through-hole), connector style (B 22), and position count (110). The HM2S70PE5100N9LF provides enhanced voltage rating (750Vrms vs. 500Vrms) and RoHS compliance. This part is suitable for direct replacement in applications where the through-hole mounting configuration is required.

HM2R66PA5100N9LF and HM2R66PA5108N9LF are functionally equivalent substitutes with modified mounting configuration. These parts feature board edge, right-angle mounting (AB 22 style) instead of standard through-hole mounting. Selection of these parts requires mechanical redesign of the PCB layout to accommodate the right-angle connector orientation. Both provide enhanced voltage rating (750Vrms) and RoHS compliance. HM2R66PA5108N9LF includes upper shield features for enhanced EMI performance.

Extended Configuration Substitute (154-Position):

HM2S70PE5101N9LF provides a 154-position configuration (110 signal positions plus 44 dedicated ground positions) with upper and lower shield features. This part is suitable for applications requiring enhanced grounding and EMI shielding. The extended position count and shield configuration represent a functional enhancement rather than a direct replacement. Selection requires verification that the PCB footprint and connector cavity can accommodate the additional ground rows.

Compliance Considerations:

All Amphenol ICC (FCI) substitute parts are RoHS compliant, whereas the TE Connectivity 352268-1 is RoHS non-compliant. Applications subject to RoHS regulations must select from the substitute parts. HM2R66PA5108N9LF, HM2S70PE5100N9LF, and HM2S70PE5101N9LF have defined REACH status (REACH Affected), providing regulatory clarity for European market applications.

Frequently Asked Questions (FAQ)

Q: Can HM2S70PE5100N9LF be used as a direct replacement for TE Connectivity 352268-1?

A: Yes. Both connectors share identical electrical specifications (1.5 A current rating, -55°C to 125°C operating range), mechanical configuration (through-hole mounting, B 22 style), and position count (110). The HM2S70PE5100N9LF provides enhanced voltage rating (750Vrms vs. 500Vrms) and RoHS compliance. No PCB redesign is required.

Q: What is the difference between HM2R66PA5100N9LF and HM2S70PE5100N9LF?

A: The primary difference is mounting style. HM2R66PA5100N9LF features board edge, right-angle mounting (AB 22 connector style), while HM2S70PE5100N9LF uses standard through-hole mounting (B 22 connector style). Both maintain 110-position count and identical electrical ratings. Selection depends on PCB layout requirements. Right-angle mounting (HM2R66PA5100N9LF) requires different PCB footprint design.

Q: What does the upper shield feature in HM2R66PA5108N9LF provide?

A: The upper shield provides electromagnetic interference (EMI) shielding for the connector cavity. This feature reduces crosstalk and improves signal integrity in high-speed or noise-sensitive applications. The standard configuration (HM2R66PA5100N9LF) does not include this shielding.

Q: When should HM2S70PE5101N9LF be selected instead of the 110-position alternatives?

A: HM2S70PE5101N9LF is selected when applications require dedicated ground connections beyond the standard 110 signal positions. The 154-position configuration includes 44 additional ground positions and upper/lower shield features. This configuration is suitable for high-current or high-frequency applications requiring enhanced grounding and EMI performance. PCB footprint verification is required before selection.

Q: Are all substitute parts compatible with existing TE Connectivity Z-PACK mating connectors?

A: Compatibility between receptacle and plug connectors depends on pitch, position count, and connector style alignment. While all substitute parts maintain the 0.079" (2.00mm) pitch and 110-position count (except HM2S70PE5101N9LF), connector style differences (B 22 vs. AB 22) and mounting configuration variations may affect mating compatibility. Verification with the corresponding mating plug connector specifications is required.

Q: What is the significance of RoHS compliance for these connectors?

A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. Applications subject to RoHS regulations (primarily European market and regulated industries) must use RoHS-compliant parts. All Amphenol ICC (FCI) substitutes are RoHS compliant, while the TE Connectivity 352268-1 is non-compliant.

Q: Can packaging differences affect part selection?

A: The TE Connectivity 352268-1 packaging is not specified in available documentation. All Amphenol ICC (FCI) substitute parts are supplied in tray packaging. Packaging differences do not affect electrical or mechanical compatibility but may impact handling, storage, and logistics procedures. Verify packaging requirements with procurement specifications.
