AF1210FR-07487RL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07487RL is a 487 Ohm ±1% 0.5W chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status with 1159 units in stock.

Substitute parts are necessary when the primary manufacturer experiences supply constraints, when design requirements mandate alternative qualified sources, or when inventory availability necessitates cross-compatible alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07487RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 487 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• Package designation: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF4870U from Panasonic Electronic Components meets all electrical and mechanical substitution criteria. Physical dimensions vary slightly (0.126" L x 0.098" W vs. 0.122" L x 0.102" W; height 0.028" vs. 0.024"), but remain within the 1210 package specification tolerance and do not affect circuit performance or PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AF1210FR-07487RL is the primary selection for new designs due to its active production status and ongoing manufacturer support. The ERJ-14NF4870U from Panasonic provides full electrical and mechanical equivalence and is suitable for replacement applications, legacy system maintenance, and supply chain diversification. However, the ERJ-14NF4870U carries a "Not For New Designs" status, indicating that Panasonic does not recommend this part for new product development.

Both parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 compliance mandates. Selection between these parts should be based on availability, supply chain strategy, and design phase (new development versus maintenance/replacement).

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF4870U be used as a direct replacement for AF1210FR-07487RL in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified, share identical electrical specifications (487 Ohms ±1%, 0.5W, ±100ppm/°C), and are packaged in 1210 (3225 Metric) format. Physical dimensions vary within standard package tolerances and do not affect circuit function or PCB layout compatibility.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF4870U?

A: This designation indicates that Panasonic does not recommend the ERJ-14NF4870U for new product development. The part remains available for replacement and legacy applications but should not be selected for designs entering production. For new designs, AF1210FR-07487RL is the appropriate choice.

Q: Are there dimensional differences that affect PCB layout?

A: The ERJ-14NF4870U is 0.004" longer and 0.004" wider than the AF1210FR-07487RL, with a maximum height 0.004" greater. These variations fall within standard 1210 package tolerances and do not require PCB footprint modification. Both parts use identical 0.05" pitch termination spacing.

Q: Do both parts meet the same compliance and certification requirements?

A: Yes. Both the AF1210FR-07487RL and ERJ-14NF4870U are ROHS3 compliant, AEC-Q200 qualified, and carry MSL 1 moisture sensitivity rating. Both are suitable for automotive and industrial applications requiring these certifications.

Q: What is the difference between the AF series and ERJ-14N series?

A: The AF series (YAGEO) and ERJ-14N series (Panasonic) are distinct product lines from different manufacturers. Both meet identical electrical and mechanical specifications for the 487 Ohm ±1% 0.5W 1210 package configuration. Selection is based on availability, supply chain preference, and design phase requirements.
