Engineering Selection Recommendations

The 1-5532903-2 serves as the direct equivalent substitute for the obsolete 1-532903-2. Both connectors are manufactured by TE Connectivity AMP Connectors and share identical electrical, mechanical, and environmental specifications across all critical parameters.

Key Differentiators:

Product Status: The 1-5532903-2 maintains active product status, ensuring long-term availability and supply chain continuity.
Regulatory Compliance: The substitute part achieves RoHS3 compliance, whereas the main part is RoHS non-compliant. This distinction is significant for applications subject to environmental regulations and procurement policies requiring RoHS-compliant components.
Packaging: The substitute is supplied in tube packaging, which may differ from the original part's packaging specification.

For applications requiring RoHS compliance or long-term component availability, the 1-5532903-2 is the appropriate selection. The electrical and mechanical compatibility is complete, with no design modifications required for direct substitution in existing PCB layouts and connector mating applications.

Frequently Asked Questions (FAQ)

Q: Are the 1-532903-2 and 1-5532903-2 mechanically interchangeable?

A: Yes. Both connectors feature identical mounting configurations (through-hole, right-angle), position counts (120), pitch spacing (0.100"), and row arrangements (4 rows). They mount identically on PCBs and mate with the same complementary connector interfaces.

Q: What is the primary reason to substitute the 1-532903-2 with the 1-5532903-2?

A: The 1-532903-2 is classified as obsolete, creating supply and long-term availability risks. The 1-5532903-2 is an active product with identical specifications, ensuring reliable procurement and supply chain support.

Q: Does the RoHS3 compliance of the 1-5532903-2 affect electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental regulations, not electrical performance. Both parts maintain identical electrical specifications, including contact finish (gold, 30.0µin), operating temperature range (-65°C to 125°C), and flammability rating (UL94 V-0).

Q: Are there packaging differences between these parts?

A: Yes. The 1-5532903-2 is supplied in tube packaging, whereas the 1-532903-2 packaging specification is not provided. Verify packaging requirements for your procurement and assembly processes.

Q: Can the 1-5532903-2 be used in existing designs originally specified for the 1-532903-2?

A: Yes. The substitute part is fully compatible with existing PCB designs, connector layouts, and mating interfaces. No design modifications are required.

Q: What is the moisture sensitivity level for both connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control measures during storage and handling.
