AF1210JR-07430RL Equivalent & Substitute Parts

Part Overview

The AF1210JR-07430RL is a 430 Ohms ±5% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for automotive and harsh environment applications. The part is currently active in production with 729 units in stock.

Substitute parts are identified when electrical parameters (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical specifications (package type, dimensions, termination count) remain identical or functionally equivalent, while allowing for variations in composition features and moisture resistance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210JR-07430RL is determined by strict equivalence in the following core parameters:

• Resistance value: 430 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package type: 1210 (3225 Metric) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Physical dimensions and termination count (exact match required)

Variations permitted in substitute parts include differences in composition features (anti-sulfur vs. moisture resistant), series designation, and automotive qualification status, provided all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

RC1210JR-07430RL serves as a direct functional equivalent to AF1210JR-07430RL. Both parts maintain identical electrical specifications (430 Ohms ±5%, 0.5W power rating) and mechanical compatibility (1210 package, identical dimensions). The RC1210JR-07430RL is ROHS3 compliant and carries unlimited moisture sensitivity rating. This substitute is suitable for applications where anti-sulfur automotive qualification is not a design requirement.

RC1210FR-07430RL offers tighter tolerance (±1% vs. ±5%) while maintaining all other electrical and mechanical parameters. This part is appropriate for applications requiring improved accuracy over the standard ±5% tolerance specification. RC1210FR-07430RL is also ROHS3 compliant with unlimited moisture sensitivity rating.

All three parts are active products with current manufacturing status and adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RC1210JR-07430RL replace AF1210JR-07430RL in automotive applications?

A: RC1210JR-07430RL is electrically and mechanically equivalent. However, AF1210JR-07430RL carries automotive AEC-Q200 qualification and anti-sulfur coating. If AEC-Q200 certification is a design requirement, AF1210JR-07430RL must be used. If automotive qualification is not specified, RC1210JR-07430RL is functionally compatible.

Q: What is the difference between RC1210JR-07430RL and RC1210FR-07430RL?

A: The primary difference is tolerance: RC1210JR-07430RL has ±5% tolerance, while RC1210FR-07430RL has ±1% tolerance. All other electrical parameters (resistance value, power rating, temperature coefficient, operating temperature range) and mechanical specifications (package, dimensions) are identical. RC1210FR-07430RL is suitable for applications requiring tighter resistance accuracy.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 1210 (3225 Metric) package with identical dimensions (0.122" L x 0.102" W, 3.10mm x 2.60mm) and maximum seated height (0.024" / 0.60mm). They are mechanically interchangeable on the same PCB layout.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable resistance variation from the nominal 430 Ohm value. AF1210JR-07430RL and RC1210JR-07430RL allow ±5% variation (408.5 to 451.5 Ohms). RC1210FR-07430RL allows ±1% variation (425.7 to 434.3 Ohms). Applications with strict resistance requirements should use RC1210FR-07430RL.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), indicating no special moisture handling requirements during storage or assembly.
