Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F1334CS are qualified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Electrical Parameters (Must Match):

• Resistance value: 1.33 MOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 0603 (1608 Metric)
• Number of terminations: 2
• Composition: Thick Film
• Moisture resistance: Required

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

Two substitute parts meet these criteria:

1. RC0603FR-071M33L (YAGEO) - Direct equivalent with identical electrical and mechanical specifications
2. CRCW06031M33FKEA (Vishay Dale) - Equivalent with automotive AEC-Q200 qualification; minor dimensional variation within tolerance

Parameter Comparison

Engineering Selection Recommendations

RC0603FR-071M33L (YAGEO) is the direct functional equivalent to RC1608F1334CS. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications. This substitute is suitable for applications where component interchangeability is required without additional qualification.

CRCW06031M33FKEA (Vishay Dale) provides equivalent electrical performance with the addition of automotive AEC-Q200 qualification. Dimensional variations are minor: length 1.55mm (vs. 1.60mm) and width 0.85mm (vs. 0.80mm), with reduced seated height of 0.50mm (vs. 0.55mm). These dimensional differences remain within standard PCB footprint tolerances for 0603 packages. This substitute is appropriate for applications requiring automotive-grade reliability or where AEC-Q200 compliance is specified.

Both substitutes maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-071M33L replace RC1608F1334CS in all applications?

A: Yes. RC0603FR-071M33L is a direct equivalent with identical electrical parameters (1.33 MOhms ±1%, 0.1W), identical package dimensions (0603/1608 Metric), and matching compliance certifications (ROHS3, MSL 1). No design modifications are required.

Q: What is the difference between RC0603FR-071M33L and CRCW06031M33FKEA?

A: Both provide equivalent 1.33 MOhms ±1% resistance and 0.1W power rating. The primary difference is that CRCW06031M33FKEA includes automotive AEC-Q200 qualification. Minor dimensional variations exist: CRCW06031M33FKEA is 1.55mm x 0.85mm with 0.50mm seated height, compared to 1.60mm x 0.80mm with 0.55mm seated height for RC0603FR-071M33L. Both fit standard 0603 PCB footprints.

Q: Are dimensional differences between substitutes significant for PCB layout?

A: No. All three components use the 0603 (1608 Metric) package standard. Dimensional variations (±0.05mm in length/width, ±0.05mm in height) are within standard PCB footprint design tolerances and do not require layout modifications.

Q: Which substitute should be selected for automotive applications?

A: CRCW06031M33FKEA is qualified to automotive AEC-Q200 standard and is the appropriate selection for automotive circuit designs. RC0603FR-071M33L and RC1608F1334CS are suitable for general-purpose applications.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All three components are ROHS3 Compliant, REACH Unaffected, and rated MSL Level 1 (Unlimited). Compliance certifications are equivalent across all options.

Q: What is the packaging difference between substitutes?

A: RC1608F1334CS and RC0603FR-071M33L are supplied in Tape & Reel (TR) packaging. CRCW06031M33FKEA is available in Cut Tape (CT) & Digi-Reel® packaging. Both packaging formats are standard for SMD component distribution and do not affect component performance.
