Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225J223CS are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 22 kOhms (exact match required)
• Package / Case: 1210 (3225 Metric) (physical and electrical compatibility)
• Composition: Thick Film (material consistency)
• Features: Moisture Resistant (environmental protection equivalence)
• Temperature Coefficient: ±100ppm/°C (thermal stability match)
• Operating Temperature Range: -55°C ~ 155°C (thermal envelope match)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Power Rating: 0.333W or higher (0.5W acceptable as upgrade)
• Manufacturer: Different manufacturers permitted if all mandatory parameters match
• Packaging: Tape & Reel acceptable as alternative to standard packaging

Both identified substitutes (RC1210FR-0722KL and RC1210JR-0722KL) meet all mandatory compatibility criteria while offering enhanced power ratings (0.5W vs. 0.333W) and improved tolerance specifications in the case of RC1210FR-0722KL.

Parameter Comparison

Engineering Selection Recommendations

RC1210FR-0722KL (YAGEO) is suitable for applications requiring tighter tolerance specifications. This substitute provides ±1% tolerance compared to the ±5% of the main part, with increased power dissipation capability (0.5W vs. 0.333W). Physical dimensions are within acceptable variance for 1210 package footprints. ROHS3 compliance and MSL 1 rating ensure regulatory and handling compatibility. Higher inventory availability (8658 pieces) supports supply chain continuity.

RC1210JR-0722KL (YAGEO) maintains tolerance equivalence (±5%) to the main part while providing increased power rating (0.5W vs. 0.333W). This substitute offers direct functional replacement with enhanced thermal performance margin. ROHS3 compliance and MSL 1 rating match the original specification. Highest inventory availability (10968 pieces) provides optimal supply chain flexibility.

Both substitutes are active products with established manufacturing status. Selection between substitutes depends on tolerance requirements: RC1210FR-0722KL for precision-critical applications, RC1210JR-0722KL for standard tolerance applications with enhanced power margin.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0722KL and RC1210JR-0722KL be used interchangeably with RC3225J223CS?

A: Both substitutes are compatible within the specified electrical and mechanical parameters. RC1210FR-0722KL provides tighter tolerance (±1% vs. ±5%), while RC1210JR-0722KL maintains tolerance equivalence. Both offer increased power rating (0.5W vs. 0.333W). Selection depends on application tolerance requirements.

Q: Are there physical footprint differences between the main part and substitutes?

A: All three parts use the 1210 (3225 Metric) package. Dimensional variations exist within acceptable tolerance: main part measures 0.126" L x 0.100" W (3.20mm x 2.55mm); substitutes measure 0.122" L x 0.102" W (3.10mm x 2.60mm). Height differences are minimal (0.026" vs. 0.024" seated maximum). These variations are within standard PCB layout tolerances for 1210 components.

Q: Do the substitute parts maintain the same environmental specifications?

A: Yes. All three parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient. Moisture resistance, ROHS3 compliance, and MSL 1 rating are identical across all parts.

Q: What is the significance of the power rating increase in the substitutes?

A: The substitutes provide 0.5W (1/2W) rating compared to the main part's 0.333W (1/3W). This represents increased thermal dissipation capability, allowing operation at higher power levels without exceeding rated specifications. Applications operating near the original 0.333W limit benefit from this margin.

Q: Are packaging format differences significant?

A: The main part uses standard packaging; substitutes are supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact electrical or mechanical compatibility. TR packaging is standard for high-volume production environments.

Q: Which substitute should be selected for new designs?

A: Selection is based on tolerance requirements. For applications requiring ±1% tolerance, RC1210FR-0722KL is specified. For standard ±5% tolerance applications, RC1210JR-0722KL provides equivalent performance with higher inventory availability. Both substitutes offer superior power rating margin compared to the original specification.
