Substitute Part Grouping Explanation

Substitute parts for the RC6432F110CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 11 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

The identified substitutes—CRCW251211R0FKEG (Vishay Dale) and ERJ-1TNF11R0U (Panasonic Electronic Components)—satisfy all electrical, mechanical, and compliance requirements. Both parts maintain identical resistance, tolerance, power rating, and temperature specifications while preserving package compatibility and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

RC6432F110CS (Samsung Electro-Mechanics): Primary selection for new designs. Active product status with continuous manufacturing support. Moisture-resistant thick film construction with MSL 1 rating suitable for standard industrial and consumer applications.

CRCW251211R0FKEG (Vishay Dale): Qualified substitute for active designs. Maintains all electrical and mechanical specifications with automotive AEC-Q200 qualification. Active product status ensures long-term availability. Tape & Reel packaging standard for high-volume production.

ERJ-1TNF11R0U (Panasonic Electronic Components): Functional equivalent with automotive AEC-Q200 qualification. Product status is "Not For New Designs," limiting use to legacy system support or replacement applications only. High inventory availability (8520 units) supports short-term supply needs for existing production lines.

Selection between RC6432F110CS and CRCW251211R0FKEG is determined by supply chain requirements and manufacturing partnerships. ERJ-1TNF11R0U substitution is restricted to non-new-design applications due to product lifecycle status.

Frequently Asked Questions (FAQ)

Q: Can CRCW251211R0FKEG replace RC6432F110CS in new designs?

A: Yes. CRCW251211R0FKEG meets all electrical specifications (11 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and mechanical requirements (2512 package, 2 terminations). Both parts are ROHS3 compliant with MSL 1 rating. The substitute maintains active product status and is suitable for new design implementation.

Q: What are the dimensional differences between these parts?

A: All three parts conform to the 2512 (6432 Metric) package standard. Minor dimensional variations exist: RC6432F110CS measures 0.248" L x 0.126" W with 0.026" max height; CRCW251211R0FKEG measures 0.248" L x 0.124" W with 0.028" max height; ERJ-1TNF11R0U measures 0.252" L x 0.126" W with 0.028" max height. These variations remain within 2512 package tolerance and do not affect PCB layout compatibility.

Q: Why is ERJ-1TNF11R0U marked "Not For New Designs"?

A: ERJ-1TNF11R0U carries a "Not For New Designs" status, indicating Panasonic has transitioned this product line. While functionally equivalent and currently in stock, this designation restricts use to legacy system maintenance and replacement applications. New designs should prioritize RC6432F110CS or CRCW251211R0FKEG.

Q: Are all three parts automotive qualified?

A: RC6432F110CS carries moisture-resistant thick film construction without explicit automotive certification. CRCW251211R0FKEG and ERJ-1TNF11R0U both feature automotive AEC-Q200 qualification, making them suitable for automotive applications requiring enhanced reliability standards.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture-related degradation. All three parts carry MSL 1 rating, eliminating moisture-related storage constraints and simplifying inventory management.

Q: Can these parts be used interchangeably in existing production?

A: Yes, within the constraints of product status. RC6432F110CS and CRCW251211R0FKEG are interchangeable for active production. ERJ-1TNF11R0U substitution is limited to non-new-design applications. Verify packaging format (bulk vs. Tape & Reel) matches your assembly process requirements.
