Engineering Selection Recommendations
The Mill-Max Manufacturing 940-44-052-24-000000 serves as a direct functional substitute for the obsolete TE Connectivity 1571541-2 based on electrical and mechanical parameter equivalence. Both components maintain identical PLCC socket specifications, pin configurations, pitch dimensions, current ratings, and contact resistance values.
Product Status Consideration: The TE Connectivity 1571541-2 is classified as obsolete, while the Mill-Max 940-44-052-24-000000 maintains active product status with significantly higher inventory availability (9554 units versus 1006 units). This status differential supports long-term supply chain continuity.
Compliance Documentation: The Mill-Max substitute provides enhanced compliance documentation. The part is ROHS3 Compliant and REACH Unaffected, whereas the original part lists RoHS status as not applicable and REACH status as vendor undefined. Both components share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
Contact Material Differences: The substitute employs beryllium copper for mating contacts and brass alloy for post contacts, compared to copper alloy materials in the original part. Both material systems maintain the specified 30mOhm contact resistance and tin plating finish. The substitute provides specified operating temperature range (-55°C ~ 125°C) not documented for the original part.
Housing Material Variation: The substitute uses polycyclohexylenedimethylene terephthalate (PCT) polyester housing versus polyphenylene sulfide (PPS) in the original. Both materials achieve UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification.
Selection of the Mill-Max substitute is supported by functional equivalence, active product status, and documented compliance certifications.
Frequently Asked Questions (FAQ)
Q: Are the TE Connectivity 1571541-2 and Mill-Max 940-44-052-24-000000 electrically interchangeable?
A: Yes. Both components are 52-position PLCC sockets with identical pitch specifications (0.100" / 2.54mm), current ratings (1 A), and contact resistance (30mOhm). Tin plating on both mating and post contacts ensures electrical compatibility.
Q: What are the key mechanical compatibility factors?
A: Both parts feature through-hole mounting, closed frame design, and solder termination. Pin grid configuration is identical at 52 positions (4 x 13). Both achieve UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.
Q: How do the contact materials differ between these parts?
A: The original TE Connectivity part uses copper alloy for both mating and post contacts. The Mill-Max substitute uses beryllium copper for mating contacts and brass alloy for post contacts. Both material systems maintain the specified 30mOhm contact resistance with tin plating.
Q: What is the significance of the housing material difference?
A: The original part uses polyphenylene sulfide (PPS) housing, while the substitute uses polycyclohexylenedimethylene terephthalate (PCT) polyester. Both materials meet UL94 V-0 flammability requirements and are suitable for through-hole PCB applications. Housing material selection does not affect electrical performance or pin compatibility.
Q: Why is product status important for this substitution?
A: The TE Connectivity 1571541-2 is classified as obsolete, creating supply chain risk for ongoing production and maintenance applications. The Mill-Max 940-44-052-24-000000 maintains active product status with substantially higher inventory availability, supporting long-term component sourcing.
Q: Are there compliance differences between these parts?
A: The Mill-Max substitute provides documented ROHS3 Compliance and REACH Unaffected status. The original part lists RoHS status as not applicable and REACH status as vendor undefined. Both components share identical ECCN (EAR99) and HTSUS (8536.69.4040) export and tariff classifications.
Q: Does the Mill-Max part specify operating temperature range?
A: Yes. The Mill-Max 940-44-052-24-000000 specifies -55°C ~ 125°C operating temperature range. The original TE Connectivity part does not provide operating temperature documentation. This specification does not affect substitution compatibility for standard industrial applications.
Q: What packaging differences exist between these parts?
A: The Mill-Max substitute is supplied in tube packaging. The original part packaging specification is not documented. Packaging format does not affect electrical or mechanical compatibility; it addresses only handling and storage considerations.
