RC0402F102CS Equivalent & Substitute Parts

Part Overview

The RC0402F102CS is a 1 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 01005 (0402 Metric) package. This component is rated for 0.03W (1/32W) power dissipation with a temperature coefficient of ±250ppm/°C and operates across the -55°C to 125°C temperature range. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in active production status with 971 pieces available in inventory.

Equivalent and substitute parts are identified when alternative manufacturers produce resistors meeting identical or compatible electrical and mechanical specifications. Substitution becomes necessary due to supply chain considerations, inventory availability, or manufacturing continuity requirements while maintaining full functional equivalence.

Substitute Part Grouping Explanation

Substitute parts for the RC0402F102CS are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters:

• Resistance value: 1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.03W / 1/32W (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

• Package / Case: 01005 (0402 Metric) (exact match required)
• Physical dimensions: 0.016" L x 0.008" W / 0.40mm x 0.20mm (exact match required)
• Height - Seated (Max): 0.006" (0.15mm) (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RC0402F102CS in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three resistor options—RC0402F102CS (Samsung Electro-Mechanics), CRCW01001K00FREL (Vishay Dale), and ERJ-XGNF1001Y (Panasonic Electronic Components)—are active production components with ROHS3 compliance and MSL 1 ratings. They are electrically and mechanically interchangeable for circuit applications requiring 1 kOhms ±1% thick film resistors in the 01005 package.

The primary distinction among these parts is the temperature coefficient specification. The RC0402F102CS and CRCW01001K00FREL both feature ±250ppm/°C, while the ERJ-XGNF1001Y offers a tighter specification of ±200ppm/°C. For applications with stringent temperature stability requirements, the ERJ-XGNF1001Y provides superior performance. For standard applications where the ±250ppm/°C specification is acceptable, all three parts are functionally equivalent.

Selection should be based on availability, supply chain requirements, and application-specific temperature stability needs. All parts carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99) and moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can CRCW01001K00FREL be used as a direct replacement for RC0402F102CS?

A: Yes. Both parts share identical electrical specifications (1 kOhms ±1%, 0.03W, ±250ppm/°C), mechanical dimensions (01005 package, 0.40mm x 0.20mm), and compliance ratings (ROHS3, MSL 1). They are direct substitutes for circuit applications.

Q: What is the difference between ERJ-XGNF1001Y and the other two options?

A: The ERJ-XGNF1001Y has a temperature coefficient of ±200ppm/°C compared to ±250ppm/°C for the RC0402F102CS and CRCW01001K00FREL. This represents improved temperature stability. All other electrical and mechanical parameters are identical.

Q: Are all three parts suitable for high-temperature applications?

A: All three parts operate across the -55°C to 125°C temperature range. The ERJ-XGNF1001Y provides tighter temperature coefficient performance (±200ppm/°C), making it preferable for applications requiring enhanced temperature stability within this operating range.

Q: Do these parts require different PCB layout considerations?

A: No. All three parts use the identical 01005 (0402 Metric) package with matching physical dimensions (0.016" L x 0.008" W, 0.006" max height). PCB footprints and assembly processes are interchangeable.

Q: Are moisture handling procedures the same for all three parts?

A: Yes. All three parts carry MSL 1 (Unlimited) ratings, indicating unlimited shelf life without moisture bake-out requirements. Handling procedures are identical across all three options.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain availability and application requirements. For applications requiring superior temperature stability, ERJ-XGNF1001Y is recommended. For standard applications, any of the three parts meets specifications. Consult current inventory and lead time data for procurement decisions.
