AF1210FR-0748R7L Equivalent & Substitute Parts

Part Overview

The AF1210FR-0748R7L is a 48.7 Ohm ±1% thick film chip resistor manufactured by YAGEO in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently in active production status. Substitute parts are necessary when the primary manufacturer's inventory is unavailable, when supply chain optimization is required, or when design flexibility across qualified alternatives is needed for production planning.

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-0748R7L is determined by strict equivalence across the following critical parameters:

• Resistance value: 48.7 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric) physical dimensions
• Composition: Thick film construction
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200 certification
• Regulatory compliance: ROHS3 and REACH requirements

The ERJ-14NF48R7U from Panasonic Electronic Components meets all substitution criteria. Both parts share identical electrical specifications, automotive-grade qualification, and regulatory compliance status. Physical dimensions vary slightly within acceptable tolerances for the 1210 package classification.

Parameter Comparison

Engineering Selection Recommendations

The AF1210FR-0748R7L is the primary selection for new designs due to its active product status and current manufacturer support. The ERJ-14NF48R7U is classified as "Not For New Designs" by Panasonic and should be reserved for legacy system maintenance, field replacements, or supply chain contingency scenarios where the primary part is unavailable.

Both parts satisfy identical electrical and regulatory requirements for automotive applications. The dimensional variations between the two parts fall within acceptable tolerances for the 1210 package classification and do not affect circuit performance or PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF48R7U be used as a direct replacement for AF1210FR-0748R7L in new automotive designs?

A: No. While ERJ-14NF48R7U meets all electrical and compliance specifications, Panasonic designates this part as "Not For New Designs." New designs must use AF1210FR-0748R7L or equivalent parts with active production status.

Q: Are there physical dimension differences that affect PCB layout?

A: Yes, minor differences exist. The ERJ-14NF48R7U is 0.004" longer, 0.004" narrower, and 0.004" taller than the AF1210FR-0748R7L. These variations remain within 1210 package tolerances and do not require PCB redesign for standard applications.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both AF1210FR-0748R7L and ERJ-14NF48R7U carry AEC-Q200 certification and are suitable for automotive-grade applications within their specified operating temperature range of -55°C to 155°C.

Q: What is the significance of the anti-sulfur feature on the AF1210FR-0748R7L?

A: The anti-sulfur protection is specific to the YAGEO part and provides enhanced reliability in environments with sulfur-containing contaminants. The Panasonic substitute does not explicitly list this feature in the provided specifications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both AF1210FR-0748R7L and ERJ-14NF48R7U are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in automotive applications.
