Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-0742R2L is determined by strict alignment of the following parameters:

• Resistance value: 42.2 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package designation: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive certification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these criteria. Physical dimensions may vary within acceptable tolerances for the 1210 package class. Product status differences are noted for design consideration.

Parameter Comparison

Engineering Selection Recommendations

CRCW121042R2FKEA (Vishay Dale) is the primary substitute for new designs. This part maintains active production status, meets all electrical and mechanical specifications, and carries identical AEC-Q200 automotive certification and ROHS3 compliance. Physical dimensions align within 1210 package tolerances. Inventory availability is 9765 pieces.

ERJ-14NF42R2U (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" status. This designation indicates the manufacturer is discontinuing or has discontinued active development for this part number. Use is limited to legacy system maintenance or existing design support where supply chain continuity is established. Height specification differs by 0.004" (0.10mm) maximum, which remains within 1210 package class tolerances. Inventory availability is 11224 pieces.

Frequently Asked Questions (FAQ)

Q: Can CRCW121042R2FKEA directly replace AF1210FR-0742R2L in automotive applications?

A: Yes. Both parts share identical electrical specifications (42.2 Ohms ±1%, 0.5W), temperature characteristics (±100ppm/°C, -55°C to 155°C), AEC-Q200 automotive rating, and ROHS3 compliance. Physical dimensions conform to 1210 package class standards. Direct substitution is valid.

Q: Why is ERJ-14NF42R2U marked "Not For New Designs"?

A: This designation reflects the manufacturer's product lifecycle status. Panasonic has classified this part number as obsolete or end-of-life for new development. Existing inventory remains available for legacy system support, but new circuit designs should specify active-status alternatives.

Q: Are there dimensional differences between these parts?

A: Minor variations exist within 1210 package tolerances. AF1210FR-0742R2L measures 0.122" × 0.102" with 0.024" maximum height. CRCW121042R2FKEA measures 0.126" × 0.098" with 0.024" maximum height. ERJ-14NF42R2U measures 0.126" × 0.098" with 0.028" maximum height. These differences remain within standard 1210 (3225 Metric) package specifications and do not affect PCB layout compatibility.

Q: Do all substitute parts carry the same certifications?

A: Yes. All three parts are AEC-Q200 rated for automotive use, ROHS3 compliant, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance documentation is equivalent across all options.

Q: Which substitute should be selected for new automotive designs?

A: CRCW121042R2FKEA is the recommended choice for new designs due to active production status and established long-term availability. This ensures supply chain continuity and design longevity.
