Electrical Parameters (Non-Negotiable):

• Resistance value of 220 Ohm
• Tolerance of ±5% or tighter
• Four isolated resistor elements
• Power rating of 62.5mW per element or higher
• Temperature coefficient of ±200ppm/°C or tighter
• Operating temperature range of -55°C to 155°C or wider

Mechanical Parameters (Non-Negotiable):

• Package designation: 0804 with convex, long-side terminals
• Eight-pin configuration
• Surface-mount technology
• Physical dimensions: 0.079" L × 0.039" W (2.00mm × 1.00mm)

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH unaffected status

All substitute parts listed below meet these criteria without exception. Substitution is valid only when all parameters align with the specified tolerances and ranges.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RP104PJ221CS - Samsung Electro-Mechanics): The original part remains the preferred choice for new designs and ongoing production. Samsung Electro-Mechanics maintains active production status with established supply channels. This part offers the lowest seated height at 0.018" (0.45mm), which may be advantageous in space-constrained applications.

Active Substitute Options:

RAVF104DJT220R (Stackpole Electronics Inc): This substitute is qualified for automotive applications under AEC-Q200 standard. Stackpole maintains active production status. The part is suitable for designs requiring automotive-grade reliability. Seated height is 0.020" (0.50mm), representing a 0.005" increase from the original part.

YC124-JR-07220RL (YAGEO): This substitute carries AEC-Q200 automotive qualification and is specified for DDRAM and SDRAM applications. YAGEO maintains active production with the highest inventory availability (13,017 pieces). The seated height is 0.022" (0.55mm). This part is suitable for consumer and industrial applications with automotive-grade requirements.

Discontinued Substitute (Not Recommended for New Designs):

MNR04MRAPJ221 (Rohm Semiconductor): This part is discontinued at DiGi Electronics and should not be selected for new designs. While electrical and mechanical parameters are equivalent, the discontinued status creates long-term supply risk. Existing inventory of 8,906 pieces may be available through alternative distribution channels for legacy product support only.

Selection Criteria Summary:

• For new designs: Select RP104PJ221CS, RAVF104DJT220R, or YC124-JR-07220RL based on application requirements and supply availability
• For automotive applications: RAVF104DJT220R or YC124-JR-07220RL are qualified options
• For space-constrained designs: RP104PJ221CS offers minimum height
• For maximum availability: YC124-JR-07220RL provides highest inventory levels
• Avoid MNR04MRAPJ221 for new designs due to discontinued status

Frequently Asked Questions (FAQ)

Q: Can I substitute RP104PJ221CS with any of the listed parts without PCB redesign?

A: Yes, all listed active substitute parts share identical package designation (0804 with convex, long-side terminals), pin count (8), and footprint dimensions (0.079" L × 0.039" W). PCB layout compatibility is maintained. However, verify clearance for seated height variations: the original part is 0.018" (0.45mm) while substitutes range from 0.020" to 0.022" (0.50mm to 0.55mm). This difference is negligible for most applications but should be confirmed in space-constrained designs.

Q: What is the difference between "Isolated" and other circuit types for resistor arrays?

A: An isolated resistor network contains four independent resistor elements with no internal connections between them. This configuration allows each resistor to be used independently in different circuit branches. The RP104PJ221CS and all substitutes maintain this isolated configuration, ensuring functional equivalence.

Q: Why is MNR04MRAPJ221 listed as discontinued?

A: MNR04MRAPJ221 is discontinued at DiGi Electronics, indicating that the manufacturer (Rohm Semiconductor) has ended active production or distribution through major channels. While the part may still be available through secondary sources or remaining inventory, it should not be specified for new designs due to supply uncertainty and lack of long-term availability assurance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all parts listed—RP104PJ221CS, MNR04MRAPJ221, RAVF104DJT220R, and YC124-JR-07220RL—are RoHS3 compliant. All are also REACH unaffected and carry Moisture Sensitivity Level 1 (unlimited shelf life without special storage requirements).

Q: Which substitute is best for automotive applications?

A: Both RAVF104DJT220R and YC124-JR-07220RL carry AEC-Q200 automotive qualification. RAVF104DJT220R is explicitly listed with automotive applications, while YC124-JR-07220RL is qualified for automotive use and specified for DDRAM and SDRAM applications. Either part is suitable for automotive designs.

Q: What does ±200ppm/°C temperature coefficient mean?

A: The temperature coefficient of ±200ppm/°C indicates the maximum change in resistance value per degree Celsius of temperature change. For a 220 Ohm resistor, this means the resistance can vary by approximately ±0.044 Ohm per degree Celsius. All listed parts maintain this specification, ensuring thermal stability equivalence.

Q: Can I use a substitute with higher power rating than 62.5mW per element?

A: Yes, a substitute with equal or higher power rating per element maintains compatibility. All listed substitutes are rated at exactly 62.5mW per element, meeting the requirement. Higher power ratings would provide additional thermal margin but are not necessary for direct substitution.

Q: What is the significance of the 0804 package designation?

A: The 0804 designation refers to the physical dimensions in hundredths of an inch: 0.080" length × 0.040" width (approximately 2.00mm × 1.00mm). This is a standard surface-mount resistor array package size. All substitute parts use identical 0804 packaging with convex, long-side terminals, ensuring PCB footprint compatibility.
