Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT68K1 is determined by strict equivalence across the following parameters:

• Resistance value: 68.1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS3 compliance (required)
• Moisture sensitivity level: 1 (Unlimited) (required)

All substitute parts listed meet these core electrical and mechanical specifications. Variations in features (such as automotive AEC-Q200 qualification or moisture-resistant construction) represent enhancements that do not prevent substitution but may provide additional benefits for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are electrically and mechanically equivalent to the RMCS1206FT68K1 and meet the core specification requirements. Selection among substitutes should be based on the following criteria:

For Active Production Applications: RMCF1206FT68K1 (Stackpole), AC1206FR-0768K1L (YAGEO), CR1206-FX-6812ELF (Bourns), CRCW120668K1FKEA (Vishay Dale), and RC1206FR-0768K1L (YAGEO) are all active products suitable for new designs.

For Automotive Applications: RMCF1206FT68K1, AC1206FR-0768K1L, CRCW120668K1FKEA, and ERJ-8ENF6812V carry AEC-Q200 automotive qualification. ERJ-8ENF6812V is marked "Not For New Designs" and should be avoided for new automotive projects.

For Enhanced Moisture Resistance: AC1206FR-0768K1L, CR1206-FX-6812ELF, and RC1206FR-0768K1L provide explicit moisture-resistant construction beyond the standard MSL 1 rating.

For Supply Chain Continuity: Multiple manufacturers (Stackpole, YAGEO, Bourns, Vishay Dale, Panasonic) provide equivalent parts, enabling sourcing flexibility and inventory management.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT68K1 replace RMCS1206FT68K1 in non-automotive applications?

A: Yes. RMCF1206FT68K1 meets all electrical and mechanical specifications of RMCS1206FT68K1. The automotive AEC-Q200 qualification is an additional feature that does not prevent use in general-purpose applications.

Q: What is the difference between anti-sulfur and moisture-resistant construction?

A: Anti-sulfur construction protects against sulfur contamination in the operating environment. Moisture-resistant construction provides enhanced protection against moisture ingress. Both are protective features; the choice depends on the specific environmental conditions of the application.

Q: Are all substitute parts pin-compatible with RMCS1206FT68K1?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with 2 terminations and are footprint-compatible. Minor dimensional variations (height, length, width) within the 1206 specification do not affect PCB assembly compatibility.

Q: Why is ERJ-8ENF6812V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued this part for new design applications. While it remains electrically equivalent and available in inventory, it should not be selected for new product development to avoid future obsolescence.

Q: Can I use CRCW120668K1FKEA if my design requires tape and reel packaging?

A: CRCW120668K1FKEA is supplied in Cut Tape (CT) & Digi-Reel® packaging. If tape and reel (TR) packaging is required, select from RMCS1206FT68K1, RMCF1206FT68K1, CR1206-FX-6812ELF, ERJ-8ENF6812V, or RC1206FR-0768K1L, which are all available in TR packaging.
