AF1206FR-07604KL Equivalent & Substitute Parts

Part Overview

The AF1206FR-07604KL is a 604 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 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 1036 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design requirements call for different feature sets such as moisture resistance or alternative automotive certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

• Resistance value: 604 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All listed substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) and packaging format (Tape & Reel vs. Cut Tape) do not affect functional equivalence but may impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Primary Active Substitutes (Recommended for New Designs)

RC1206FR-07604KL (YAGEO) and CR1206-FX-6043ELF (Bourns Inc.) are both active production parts suitable for new designs. RC1206FR-07604KL maintains YAGEO manufacturer continuity with moisture-resistant features. CR1206-FX-6043ELF provides cross-manufacturer qualification from Bourns Inc. with equivalent electrical specifications.

CRCW1206604KFKEA (Vishay Dale) is an active production part with AEC-Q200 automotive qualification matching the original part's feature set.

Legacy Substitute (Not Recommended for New Designs)

ERJ-8ENF6043V (Panasonic Electronic Components) is marked as "Not For New Designs" and should be used only for legacy system maintenance or repair applications where design continuity is required.

Feature Considerations

The original AF1206FR-07604KL includes anti-sulfur coating with AEC-Q200 qualification. Substitute parts RC1206FR-07604KL and CR1206-FX-6043ELF feature moisture resistance instead. CRCW1206604KFKEA and ERJ-8ENF6043V maintain AEC-Q200 automotive qualification. All parts are ROHS3 compliant with MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07604KL replace AF1206FR-07604KL in automotive applications?

A: Yes. Both parts meet the core electrical requirements (604 kOhms ±1%, 0.25W, 1206 package, ±100ppm/°C, -55°C to 155°C). RC1206FR-07604KL substitutes moisture resistance for anti-sulfur coating. Both are ROHS3 compliant with MSL 1 rating. Verify application-specific requirements for coating preference.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is continuous reel format suitable for high-volume automated assembly. Cut Tape & Digi-Reel is pre-cut tape format suitable for lower-volume or mixed-component assembly. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Is ERJ-8ENF6043V suitable for new product designs?

A: No. ERJ-8ENF6043V is marked "Not For New Designs" by Panasonic. Use this part only for legacy system maintenance or repair. For new designs, select from active production parts: RC1206FR-07604KL, CR1206-FX-6043ELF, or CRCW1206604KFKEA.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist. AF1206FR-07604KL and RC1206FR-07604KL are 0.122" L × 0.063" W with 0.026" max height. CR1206-FX-6043ELF, CRCW1206604KFKEA, and ERJ-8ENF6043V are 0.126" L × 0.063" W with heights ranging from 0.024" to 0.030". These differences are within standard 1206 package tolerance and do not affect PCB layout compatibility.

Q: Which substitute part has the highest inventory availability?

A: ERJ-8ENF6043V has 137,935 units in stock. However, due to its "Not For New Designs" status, RC1206FR-07604KL (44,435 units) or CRCW1206604KFKEA (14,815 units) are preferred for active projects.
