Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2370CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 237 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Equivalence Requirements:

• Package designation: 2512 (6432 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: within ±0.010" tolerance on length and width

Compliance Requirements:

• RoHS3 compliance (mandatory)
• Moisture Sensitivity Level 1 (mandatory)
• REACH Unaffected status (mandatory)

All four substitute parts listed below satisfy these equivalence criteria. Differences in dimensional tolerances (height seated maximum, length/width variations within ±0.010") do not affect functional interchangeability in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

RC2512FK-07237RL (YAGEO) is a direct equivalent with Active product status. This part maintains identical electrical and mechanical specifications with 8626 pieces in inventory. Packaging is supplied as Tape & Reel format suitable for automated assembly processes.

CRCW2512237RFKEG (Vishay Dale) is functionally equivalent with Active product status and includes AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade reliability. Inventory availability is 4322 pieces.

RMCF2512FT237R (Stackpole Electronics Inc) is functionally equivalent with Active product status and AEC-Q200 automotive qualification. This part offers the highest current inventory at 56538 pieces, providing superior supply chain availability. Dimensions match the original part exactly (0.248" L x 0.126" W).

Secondary Substitute (Not For New Designs):

ERJ-1TNF2370U (Panasonic Electronic Components) is functionally equivalent but carries "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies. New design implementations should not specify this part number. Inventory is 7941 pieces.

Selection Criteria:

For new designs, select from RC2512FK-07237RL, CRCW2512237RFKEG, or RMCF2512FT237R based on supply chain requirements and packaging preferences. For automotive applications requiring AEC-Q200 qualification, specify either CRCW2512237RFKEG or RMCF2512FT237R. For maximum inventory availability, RMCF2512FT237R is the optimal choice.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-07237RL replace RC6432F2370CS in existing designs?

A: Yes. RC2512FK-07237RL is electrically and mechanically equivalent. Both parts share identical resistance (237 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 2512 package designation. Physical dimensions are within acceptable tolerance (RC2512FK-07237RL: 6.35mm L x 3.10mm W versus RC6432F2370CS: 6.30mm L x 3.20mm W). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between moisture-resistant and AEC-Q200 qualified parts?

A: The RC6432F2370CS features moisture-resistant construction with MSL 1 rating, suitable for general industrial applications. CRCW2512237RFKEG and RMCF2512FT237R include AEC-Q200 automotive qualification in addition to moisture resistance, meeting stricter reliability and testing requirements for automotive environments. Both feature sets are ROHS3 compliant and operate across identical temperature ranges.

Q: Why is ERJ-1TNF2370U marked "Not For New Designs"?

A: ERJ-1TNF2370U carries "Not For New Designs" status, indicating Panasonic has transitioned this product line. The part remains functionally equivalent and suitable for replacement applications. New circuit designs should specify RC2512FK-07237RL, CRCW2512237RFKEG, or RMCF2512FT237R to ensure long-term supply continuity.

Q: Are tape and reel packaged parts compatible with bulk packaged parts in assembly?

A: Yes. Tape & Reel (TR) packaging is standard for automated pick-and-place assembly. Bulk packaging is typically used for manual assembly or small-volume production. Both packaging formats contain identical components. Assembly equipment compatibility depends on feeder specifications, not component equivalence.

Q: What are the dimensional tolerances for 2512 package substitution?

A: All listed substitutes maintain 2512 (6432 Metric) package designation. Length variations range from 6.30mm to 6.40mm (±0.05mm tolerance). Width variations range from 3.10mm to 3.20mm (±0.05mm tolerance). Height seated maximum ranges from 0.65mm to 0.70mm. These variations are within standard PCB assembly process tolerances and do not affect functional interchangeability or reflow soldering performance.

Q: Which substitute offers the best supply chain availability?

A: RMCF2512FT237R (Stackpole Electronics Inc) offers the highest inventory at 56538 pieces. This part is Active status, AEC-Q200 qualified, and maintains exact dimensional match to the original RC6432F2370CS (0.248" L x 0.126" W, 6.30mm x 3.20mm).
