Engineering Selection Recommendations

CSRL1-0R005F1 and CSRL1-0R005F8 are direct Riedon equivalents with active product status. Both maintain identical electrical specifications and RoHS3 compliance. The primary difference is packaging format: CSRL1-0R005F1 is supplied in standard packaging, while CSRL1-0R005F8 is supplied in Tape & Reel format for automated assembly. Selection between these two depends on procurement and assembly requirements.

CRF1206-FZ-R005ELF is a Bourns Inc. alternative that meets all core electrical and mechanical requirements. This part includes AEC-Q200 automotive qualification and moisture-resistant construction, providing enhanced reliability for demanding applications. The slightly increased height (0.031" vs. 0.024") must be verified against PCB layout constraints.

For applications requiring the lowest profile, CSRL1-0R005F1 offers the minimum seated height at 0.024". For high-volume automated assembly, CSRL1-0R005F8 in Tape & Reel packaging is recommended. For automotive or moisture-critical applications, CRF1206-FZ-R005ELF provides additional qualification and protective features.

Frequently Asked Questions (FAQ)

Q: Can CSRL1-0R005F8 be used as a direct replacement for CSR1206-0R005F1?

A: Yes. Both parts share identical electrical specifications (5 mOhms ±1%, 1W), package type (1206), composition (Metal Element), and operating temperature range (-55°C ~ 170°C). The difference is packaging format: CSRL1-0R005F8 is supplied in Tape & Reel format for automated assembly, while CSR1206-0R005F1 was supplied in standard packaging.

Q: What is the difference between CSRL1-0R005F1 and CSRL1-0R005F8?

A: Both are Riedon CSRL series parts with identical electrical performance. CSRL1-0R005F1 is supplied in standard packaging, while CSRL1-0R005F8 is supplied in Tape & Reel (TR) format. Selection depends on assembly method: manual assembly typically uses standard packaging, while automated pick-and-place assembly uses Tape & Reel format.

Q: Can CRF1206-FZ-R005ELF be used in place of the original CSR1206-0R005F1?

A: Yes. CRF1206-FZ-R005ELF meets all core electrical and mechanical requirements. However, the seated height is 0.031" compared to the original 0.024", and dimensions are slightly larger (0.126" L x 0.065" W vs. 0.126" L x 0.063" W). PCB layout must accommodate these dimensional differences. The part includes AEC-Q200 automotive qualification and moisture-resistant features not present in the original.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), matching the original CSR1206-0R005F1 specifications.

Q: What is the temperature coefficient difference between substitutes?

A: CSR1206-0R005F1 and CRF1206-FZ-R005ELF both specify ±50ppm/°C. CSRL1-0R005F1 specifies ±75ppm/°C, representing slightly higher temperature-dependent resistance variation. CSRL1-0R005F8 does not specify temperature coefficient. For applications requiring maximum temperature stability, CSR1206-0R005F1 or CRF1206-FZ-R005ELF are preferred.

Q: Which substitute offers the best availability?

A: CRF1206-FZ-R005ELF from Bourns Inc. has the highest inventory at 20,998 pieces. CSRL1-0R005F8 has 5,981 pieces in stock. CSRL1-0R005F1 has 636 pieces available.
