Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608J625CS is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 6.2 MOhms (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Power rating: 0.1W (1/10W) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Secondary Compatibility Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Temperature coefficient: ±100ppm/°C or ±200ppm/°C (acceptable variance)
• Moisture sensitivity: MSL Level 1 (Unlimited) or equivalent
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) (interchangeable for component selection)

Two substitute parts meet these criteria: RC1608F625CS (Samsung Electro-Mechanics, ±1% tolerance upgrade) and RMCF0603JT6M20 (Stackpole Electronics Inc, automotive-grade AEC-Q200 rated).

Parameter Comparison

Engineering Selection Recommendations

RC1608F625CS (Samsung Electro-Mechanics): This substitute offers improved tolerance specification (±1% versus ±5%), maintaining identical electrical and thermal characteristics with the main part. Both components share Samsung Electro-Mechanics manufacturing, ROHS3 compliance, and MSL Level 1 rating. Selection of this substitute is appropriate for applications requiring tighter resistance tolerance while preserving all other performance parameters. Packaging format differs (Cut Tape versus Tape & Reel), which affects procurement and assembly processes but not component functionality.

RMCF0603JT6M20 (Stackpole Electronics Inc): This substitute maintains ±5% tolerance matching the main part and provides automotive-grade AEC-Q200 qualification. Temperature coefficient specification is ±200ppm/°C (versus ±100ppm/°C for the main part), representing acceptable variance within thick film resistor manufacturing standards. ROHS3 compliance and MSL Level 1 rating are equivalent. Selection of this substitute is appropriate for applications requiring automotive-qualified components or when Stackpole sourcing is preferred. Tape & Reel packaging matches the main part format.

Both substitutes maintain full electrical and mechanical compatibility with RC1608J625CS across all critical parameters and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can RC1608F625CS be used as a direct replacement for RC1608J625CS?

A: Yes. Both components share identical resistance (6.2 MOhms), power rating (0.1W), package (0603), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL Level 1). RC1608F625CS provides tighter tolerance (±1% versus ±5%), which is a functional upgrade. The only difference is packaging format (Cut Tape versus Tape & Reel), which affects procurement and assembly logistics but not component performance.

Q: Can RMCF0603JT6M20 be used as a direct replacement for RC1608J625CS?

A: Yes. Both components share identical resistance (6.2 MOhms), tolerance (±5%), power rating (0.1W), package (0603), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL Level 1). RMCF0603JT6M20 includes automotive AEC-Q200 qualification and has a temperature coefficient of ±200ppm/°C (versus ±100ppm/°C), which is within acceptable thick film resistor specifications. Packaging format (Tape & Reel) matches the main part.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: resistance value (6.2 MOhms exact), package format (0603 exact), power rating (0.1W exact), composition (thick film exact), operating temperature range (-55°C to 155°C minimum), and RoHS compliance (ROHS3 minimum). Tolerance, temperature coefficient, and moisture sensitivity must meet or exceed the main part specifications. Packaging format (Tape & Reel or Cut Tape) affects procurement but not functional compatibility.

Q: Are there differences in temperature coefficient between the main part and substitutes?

A: RC1608J625CS and RC1608F625CS both specify ±100ppm/°C. RMCF0603JT6M20 specifies ±200ppm/°C. Both values are within standard thick film resistor performance ranges and do not affect functional interchangeability across the -55°C to 155°C operating range.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect component selection?

A: Packaging format affects procurement, storage, and assembly processes but does not affect electrical or mechanical component performance. RC1608J625CS and RMCF0603JT6M20 are supplied in Tape & Reel format. RC1608F625CS is supplied in Cut Tape format. Selection should be based on assembly equipment compatibility and procurement requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. RC1608J625CS, RC1608F625CS, and RMCF0603JT6M20 are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for electronics manufacturing.
