Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5352521-1 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Parameters:

• Number of Positions: 154 (110 + 44 Ground)
• Pitch: 0.079" (2.00mm)
• Number of Rows: 5 + 2
• Connector Type: Header, Male Pins
• Connector Style: A 22
• Mounting Type: Through Hole
• Termination: Press-Fit
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Compliance: ROHS3 Compliant or RoHS Compliant

All substitute parts listed maintain these core parameters. Variations in current rating, voltage rating, contact finish thickness, and connector usage do not preclude substitution when the above parameters align. Substitute parts are sourced from HARTING (har-bus® HM series) and Amphenol ICC/FCI (Millipacs® series), both established manufacturers of backplane connector solutions.

Parameter Comparison

Engineering Selection Recommendations

HARTING har-bus® HM Series (17011541001, 17011541603, 17011542001, 17011542603)

The HARTING har-bus® HM series connectors provide direct functional equivalence to the 5352521-1 across all critical mechanical and electrical parameters. All four HARTING variants maintain active product status, ROHS3 compliance, and identical operating temperature specifications. These parts are available in tube packaging with higher inventory levels (836–1427 pieces) compared to the obsolete TE part. The HARTING series is suitable for general backplane applications and CompactPCI P4 implementations (17011541603 and 17011542603 variants).

Amphenol ICC Millipacs® Series (HM2P07PDJ341N9LF, HM2P07PNK354GFLF)

The Amphenol ICC Millipacs® series connectors deliver equivalent mechanical compatibility with enhanced electrical performance characteristics. Both variants feature 1.5A current rating and 750Vrms voltage rating compared to the TE part's 1.5A and 500Vrms specifications. These parts maintain RoHS compliance and active product status. Amphenol ICC parts are packaged in trays with inventory availability of 851–870 pieces. The Millipacs® series is designated for applications requiring higher voltage tolerance.

Product Status Consideration

All substitute parts listed maintain active product status, ensuring long-term availability and continued manufacturer support. The obsolete status of the 5352521-1 necessitates transition to one of these active alternatives for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can HARTING har-bus® HM series connectors directly replace the TE Connectivity 5352521-1?

A: Yes. The HARTING 17011541001, 17011541603, 17011542001, and 17011542603 connectors maintain identical position count (154), pitch (2.00mm), row configuration (5+2), connector type (Header, Male Pins), mounting method (Through Hole), termination type (Press-Fit), and operating temperature range (-55°C ~ 125°C). All variants are ROHS3 compliant and carry MSL 1 rating.

Q: What is the difference between HARTING variants 17011541001 and 17011541603?

A: Both connectors share identical mechanical and electrical specifications. The primary distinction is connector usage designation: 17011541001 is specified for general backplane applications, while 17011541603 is designated for CompactPCI P4 implementations. Electrical and mechanical compatibility remains equivalent.

Q: How do Amphenol ICC Millipacs® parts compare to HARTING alternatives?

A: Amphenol ICC HM2P07PDJ341N9LF and HM2P07PNK354GFLF maintain identical mechanical parameters and position configuration. The key difference is electrical performance: Amphenol ICC parts provide 750Vrms voltage rating versus HARTING's unspecified voltage rating and the original TE part's 500Vrms. Both Amphenol ICC variants deliver 1.5A current rating matching the TE part. Amphenol ICC parts carry RoHS compliance (versus ROHS3 for HARTING) and REACH Affected status (versus REACH Unaffected for HARTING).

Q: What packaging options are available for substitute parts?

A: HARTING har-bus® HM series connectors are supplied in tube packaging. Amphenol ICC Millipacs® series connectors are supplied in tray packaging. Packaging selection may influence handling, storage, and integration procedures in manufacturing environments.

Q: Are all substitute parts suitable for CompactPCI P4 applications?

A: HARTING variants 17011541603 and 17011542603 are explicitly designated for CompactPCI P4 connector usage. HARTING 17011541001 and 17011542001 are designated for general backplane usage. Amphenol ICC Millipacs® parts do not specify connector usage designation. Application-specific requirements should be evaluated against designated usage parameters.

Q: What is the inventory status of substitute parts?

A: HARTING 17011542603 offers the highest inventory availability at 1427 pieces. HARTING 17011542001 provides 1167 pieces. HARTING 17011541603 provides 836 pieces. HARTING 17011541001 provides 985 pieces. Amphenol ICC HM2P07PDJ341N9LF provides 870 pieces, and HM2P07PNK354GFLF provides 851 pieces. All substitute parts are listed as new original stock.

Q: Do substitute parts maintain the same contact finish specifications?

A: The TE 5352521-1 specifies gold contact finish at 30.0µin (0.76µm) thickness. HARTING har-bus® HM series connectors specify gold or gold-palladium contact finish without thickness specification. Amphenol ICC Millipacs® connectors specify gold contact finish at 30.0µin (0.76µm) thickness, matching the original part exactly.

Q: Are all substitute parts ROHS compliant?

A: Yes. HARTING har-bus® HM series connectors are ROHS3 compliant. Amphenol ICC Millipacs® connectors are RoHS compliant. Both compliance levels satisfy RoHS regulatory requirements for electronic components.
