Substitute Part Grouping Explanation

Substitution of the obsolete CSR2512B0R005F9 is based on the following critical parameters:

Package Compatibility: The substitute part must utilize the 2512 (6432 Metric) package format to ensure mechanical and electrical fit within existing PCB layouts and assembly processes.

Manufacturer Consistency: Riedon manufactures both the original and substitute part, ensuring design continuity and supply chain reliability.

Regulatory Compliance: Both parts maintain identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications, confirming export and tariff compliance equivalence.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture handling and storage requirements.

The substitute part CSRL3-0R005F9 meets all substitution criteria through matching package geometry, manufacturer origin, and regulatory classifications.

Engineering Selection Recommendations

The CSRL3-0R005F9 serves as the direct active substitute for the obsolete CSR2512B0R005F9. Selection is based on the following engineering factors:

Product Status Transition: The substitute part maintains active production status, ensuring long-term availability and supply continuity compared to the obsolete original part.

Regulatory Alignment: Both parts share identical ECCN and HTSUS classifications, confirming equivalent export control and tariff treatment. The substitute part carries explicit ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Package Standardization: The 2512 (6432 Metric) package format is maintained across both parts, ensuring direct PCB layout compatibility without redesign requirements.

Moisture Handling: MSL 1 (Unlimited) rating on both parts confirms identical moisture sensitivity characteristics and storage protocol requirements.

Frequently Asked Questions (FAQ)

Q: Can the CSRL3-0R005F9 be used as a direct replacement for the CSR2512B0R005F9?

A: Yes. Both parts share the 2512 (6432 Metric) package format, identical MSL rating, and matching regulatory classifications (ECCN and HTSUS). The substitute part is manufactured by the same supplier (Riedon) and maintains active production status.

Q: What are the physical dimensions of the substitute part?

A: The CSRL3-0R005F9 measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with a maximum seated height of 0.035" (0.90mm). These dimensions are consistent with the 2512 package standard.

Q: Are there any compliance differences between the original and substitute parts?

A: No compliance differences exist. Both parts carry EAR99 ECCN classification and 8533.21.0030 HTSUS code. The substitute part includes explicit ROHS3 compliance and REACH unaffected status documentation.

Q: What is the moisture sensitivity level for the substitute part?

A: The CSRL3-0R005F9 carries MSL 1 (Unlimited) rating, identical to the original part. This indicates unlimited shelf life under normal storage conditions without moisture bake requirements.

Q: How many terminations does the substitute part have?

A: The CSRL3-0R005F9 has 2 terminations, consistent with standard chip resistor configuration for the 2512 package format.
