Engineering Selection Recommendations
Primary Recommendation for RoHS3 Compliant Applications:
The Mill-Max Manufacturing Corp. 115-43-318-41-001000 and 115-43-318-41-003000 are the preferred direct substitutes for the TE Connectivity 4-1571552-5. Both parts maintain ROHS3 compliance, matching the original part's regulatory status. The 115-43-318-41-001000 offers identical electrical and mechanical specifications with standard post length of 0.108" (2.74mm), while the 115-43-318-41-003000 provides the same performance in tube packaging.
Alternative Recommendation for Extended Temperature Range:
The Mill-Max 110-43-318-41-605000 and 111-43-318-41-001000 provide ROHS3 compliance with extended operating temperature to 125°C and contact resistance specification of 10mOhm, matching the original part. The 111-43-318-41-001000 features an extended post length of 0.170" (4.32mm) for applications requiring deeper PCB penetration.
Substitutes for Non-RoHS Applications:
The Mill-Max 110-41-318-41-001000, 110-91-318-41-001000, 110-93-318-41-001000, and 110-99-318-41-001000 are functionally equivalent but vary in contact finish specifications and RoHS compliance status. The 110-41-318-41-001000 maintains ROHS3 compliance with gold mating contacts and tin post finish. The 110-91-318-41-001000, 110-93-318-41-001000, and 110-99-318-41-001000 are RoHS non-compliant and suitable only for applications without RoHS requirements.
Tin-Plated Alternative:
The Mill-Max 110-44-318-41-001000 provides tin-plated mating contacts with ROHS3 compliance for applications where tin finish is specified.
Frequently Asked Questions (FAQ)
Q: Can the Mill-Max 115-43-318-41-001000 directly replace the TE Connectivity 4-1571552-5 on existing PCBs?
A: Yes. The 115-43-318-41-001000 maintains identical pin count (18 positions), pitch (0.100"), row spacing (0.3"), mounting type (through-hole), and termination method (solder). The post length of 0.108" (2.74mm) is shorter than the original 0.125" (3.18mm), which is acceptable for standard PCB thicknesses. Verify PCB hole depth specifications if custom board designs are used.
Q: What is the difference between the 115-43-318-41-001000 and 115-43-318-41-003000?
A: Both parts are electrically and mechanically identical. The primary difference is packaging: the 115-43-318-41-001000 is supplied in tube packaging, while the 115-43-318-41-003000 is also supplied in tube packaging. Consult inventory and procurement requirements for packaging preference.
Q: Are the Mill-Max parts with Tin-Lead post finish (110-91-318-41-001000, 110-93-318-41-001000, 110-99-318-41-001000) suitable for RoHS-regulated applications?
A: No. These parts are marked as RoHS non-compliant due to tin-lead content. They are restricted for use in applications subject to RoHS3 regulations. Use only ROHS3 compliant alternatives such as 115-43-318-41-001000, 110-41-318-41-001000, 110-43-318-41-605000, 111-43-318-41-001000, or 110-44-318-41-001000.
Q: What is the significance of the extended post length on the 111-43-318-41-001000?
A: The 111-43-318-41-001000 features a termination post length of 0.170" (4.32mm) compared to the standard 0.125" (3.18mm). This extended length accommodates thicker PCBs or applications requiring deeper solder joint penetration. Standard PCB applications use the 0.125" post length variants.
Q: Does the contact finish thickness variation affect electrical performance?
A: Contact finish thickness variations (10.0µin to 30.0µin for gold) do not affect electrical performance within the specified operating parameters. All variants maintain the same contact resistance and current rating specifications. Selection is based on application durability and environmental requirements.
Q: Can I use the 110-44-318-41-001000 (tin mating finish) as a substitute for the gold-plated original?
A: The 110-44-318-41-001000 is electrically and mechanically compatible but features tin-plated mating contacts instead of gold. This substitution is acceptable for applications where contact finish material is not specified. Verify design requirements for corrosion resistance and contact reliability in your specific environment.
Q: What is the current rating for all substitute parts?
A: All Mill-Max substitute parts are rated for 3 A continuous current, which exceeds the original TE Connectivity part specifications. This provides additional design margin for applications with moderate current requirements.
Q: Are all substitute parts available in the same packaging as the original?
A: All substitute parts are supplied in tube packaging. The original TE Connectivity 4-1571552-5 packaging specification was not provided in the technical data. Confirm packaging requirements with procurement specifications.
