Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 5536504-2
The TE Connectivity 5536504-2 is the direct successor to the obsolete 5223611-1. This part maintains identical electrical and mechanical specifications while offering active product status and significantly higher inventory availability (56,100 units). Both parts share the same Z-PACK series designation, identical connector configuration, and equivalent compliance certifications. Selection of 5536504-2 ensures continuity with the original design intent and manufacturer support.
Secondary Recommendations: Amphenol ICC (FCI) Metral® Series
The Amphenol ICC (FCI) Metral® series connectors (58355-130LF, 70298-1102LF through 70298-1118LF) provide cross-manufacturer equivalence for applications where multi-source qualification is required. All Amphenol alternatives meet the critical electrical and mechanical parameters: 48 positions, 0.079" pitch, 4-row configuration, through-hole press-fit termination, gold contacts, and -55°C to 125°C operating range. All parts carry RoHS compliance, UL94 V-0 flammability rating, and MSL 1 classification.
Compliance Considerations:
All substitute parts maintain RoHS compliance and EAR99 export classification consistent with the original part. The Amphenol alternatives carry REACH Affected status, whereas the TE Connectivity parts show Vendor Undefined REACH status. Organizations subject to REACH regulations should confirm applicability with their compliance department.
Inventory and Availability:
The TE Connectivity 5536504-2 offers the highest inventory availability at 56,100 units. Amphenol alternatives range from 821 to 1,142 units across the Metral® series variants, providing adequate supply for production requirements.
Frequently Asked Questions (FAQ)
Q: Can the Amphenol ICC (FCI) Metral® series parts directly replace the TE Connectivity 5223611-1?
A: Yes. All Amphenol alternatives listed meet the critical compatibility parameters: 48 positions, 0.079" (2.00mm) pitch, 4-row configuration, through-hole mounting, press-fit termination, gold contact finish, natural color, -55°C to 125°C operating temperature, UL94 V-0 flammability rating, RoHS compliance, and MSL 1 rating. Electrical and mechanical compatibility is established through these parameters.
Q: What is the difference between the multiple Amphenol 70298 variants?
A: The 70298 series variants (70298-1102LF through 70298-1118LF) are all electrically and mechanically equivalent for the purposes of substituting the 5223611-1. All variants share identical connector specifications: 48 positions, 0.079" pitch, 4-row configuration, through-hole press-fit termination, gold contacts, and -55°C to 125°C operating range. Differences between variants relate to internal design features not specified in the provided parameters. Selection among these variants may be based on inventory availability or internal design requirements.
Q: Why does the 58355-130LF have a 1.5A current rating while other Amphenol parts specify 1A?
A: The 58355-130LF is rated for 1.5A per contact, while the 70298 series variants are rated for 1A per contact. Both ratings exceed typical backplane connector applications. Selection should be based on specific circuit current requirements. The original 5223611-1 does not specify a current rating, so either rating is acceptable for applications previously using the TE part.
Q: Is the TE Connectivity 5536504-2 preferred over Amphenol alternatives?
A: The TE Connectivity 5536504-2 is the direct manufacturer replacement for the obsolete 5223611-1 and maintains identical specifications and series designation. For applications where single-source qualification exists or where design continuity with the original manufacturer is required, 5536504-2 is the appropriate selection. For applications requiring multi-source qualification or where Amphenol parts are already qualified, the Metral® series alternatives provide equivalent functionality.
Q: Are there any voltage or current limitations when substituting these parts?
A: The original 5223611-1 is rated for 30V. The TE Connectivity 5536504-2 maintains this 30V rating. The Amphenol alternatives do not specify a voltage rating in the provided data. For applications operating at 30V or below, all listed substitutes are compatible. Applications exceeding 30V should be limited to the TE Connectivity parts with specified 30V ratings.
Q: What is the significance of the contact finish thickness specification on Amphenol parts?
A: The Amphenol alternatives specify 30.0µin (0.76µm) gold contact finish thickness. The TE Connectivity parts do not provide this specification. The specified thickness on Amphenol parts indicates a defined manufacturing standard that ensures consistent contact resistance and durability. This specification does not affect substitution compatibility.
Q: Can these connectors be used in new designs or only as replacements for existing applications?
A: All substitute parts listed carry active product status (except the original 5223611-1, which is obsolete). The TE Connectivity 5536504-2 and all Amphenol Metral® series parts are suitable for both replacement applications and new designs. For new designs, the TE Connectivity 5536504-2 is recommended as the direct successor to the obsolete 5223611-1.
Q: What packaging is available for these connectors?
A: The TE Connectivity 5536504-2 is supplied in tube packaging. All Amphenol Metral® series alternatives are supplied in tube packaging. Tube packaging is standard for through-hole connectors and is suitable for both manual and automated assembly processes.
