Substitute Part Grouping Explanation
Substitution eligibility for the CAY10-220J2LF is determined by strict equivalence across the following parameters:
- Resistance value: 22 Ohm
- Tolerance: ±5%
- Number of resistors: 2
- Circuit type: Isolated
- Package / Case: 0404 (1010 Metric), Convex
- Number of pins: 4
- Mounting type: Surface Mount
- RoHS compliance: ROHS3 Compliant
- Moisture sensitivity level: 1 (Unlimited)
All substitute parts listed meet these core electrical and mechanical requirements. Variations in temperature coefficient, power per element, and operating temperature range are noted but do not disqualify substitution when the primary part is unavailable.

Engineering Selection Recommendations
Primary Substitutes (Active Status, Equivalent Specifications)
741X043220JP (CTS Resistor Products) and EXB-24V220JX (Panasonic Electronic Components) are the preferred substitutes. Both maintain Active product status, ROHS3 compliance, and operate within the -55°C to 125°C temperature range matching the original specification. The 741X043220JP offers marginally higher power per element (63mW vs 62.5mW) with improved temperature coefficient (±200ppm/°C vs ±250ppm/°C). EXB-24V220JX maintains identical power rating and temperature coefficient performance.
Secondary Substitutes (Extended Temperature Range)
RAVF102DJT22R0 (Stackpole Electronics Inc) and YC122-JR-0722RL (YAGEO) provide extended operating temperature range to 155°C with Active product status and ROHS3 compliance. These are suitable when thermal margin requirements exceed the original -55°C to 125°C specification.
Discontinued Alternative
MNR02MRAPJ220 (Rohm Semiconductor) is listed as Discontinued at DiGi Electronics and should be avoided for new designs despite meeting electrical specifications.
Frequently Asked Questions (FAQ)
Q: Can I substitute CAY10-220J2LF with any of the listed parts without design modification?
A: Yes. All listed substitute parts share identical resistance value (22 Ohm), tolerance (±5%), circuit type (Isolated), package (0404 1010 Metric), pin count (4), and mounting type (Surface Mount). Electrical performance remains equivalent within the specified operating temperature ranges.
Q: What is the difference between the temperature coefficient values?
A: The CAY10-220J2LF specifies ±250ppm/°C, while most substitutes specify ±200ppm/°C. The lower coefficient in substitute parts indicates superior temperature stability. This difference is not a limitation but an improvement for temperature-sensitive applications.
Q: Are there packaging differences I should consider?
A: Yes. The CAY10-220J2LF is supplied in Tape & Reel (TR) packaging. Alternatives include 741X043220JP and EXB-24V220JX in Tape & Reel, while MNR02MRAPJ220 and YC122-JR-0722RL are supplied in Cut Tape (CT) formats. Verify your assembly equipment compatibility with the selected packaging format.
Q: Which substitute offers the best thermal performance?
A: RAVF102DJT22R0 and YC122-JR-0722RL extend the operating temperature range to -55°C to 155°C, providing 30°C additional margin above the original specification. Both maintain ±200ppm/°C temperature coefficient.
Q: Is MNR02MRAPJ220 suitable for new designs?
A: No. MNR02MRAPJ220 is marked as Discontinued at DiGi Electronics. For new designs, select from Active status alternatives: 741X043220JP, EXB-24V220JX, RAVF102DJT22R0, or YC122-JR-0722RL.
Q: Do all substitutes maintain ROHS3 compliance?
A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original CAY10-220J2LF specification.
