Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 249 Ohms
• Tolerance: ±1%
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C ~ 155°C
• RoHS3 Compliance
• MSL 1 Rating

Grouping Logic:

Group 1 - Direct Equivalents (1/8W Power Rating): Parts with identical 0.125W power rating, AEC-Q200 automotive qualification, and anti-sulfur or moisture-resistant features. These provide drop-in replacement capability with no circuit redesign required.

Group 2 - Higher Power Rating Substitutes (1/2W Power Rating): Parts with 0.5W power rating in the same 0805 package. These are electrically compatible and physically interchangeable but provide increased power dissipation capability. Suitable for applications where thermal margin enhancement is beneficial.

All substitute parts maintain the same resistance, tolerance, temperature coefficient, and operating temperature range as the primary part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification):

ERJ-6ENF2490V (Panasonic), AC0805FR-07249RL (YAGEO), CRCW0805249RFKEA (Vishay Dale), and RMCF0805FT249R (Stackpole Electronics) are functionally equivalent to the ERJ-S06F2490V with identical 0.125W power rating. All maintain AEC-Q200 automotive qualification and ROHS3 compliance. These parts are suitable for direct substitution in automotive and industrial applications requiring consistent thermal and electrical performance.

For Enhanced Thermal Performance:

CRCW0805249RFKEAHP and RCS0805249RFKEA provide 0.5W power rating in the same 0805 package footprint. These parts are physically compatible and electrically equivalent but offer increased power dissipation capability. Selection is appropriate when circuit design allows higher power rating or when thermal margin enhancement is required.

For Non-Automotive Applications:

CR0805-FX-2490ELF (Bourns) lacks AEC-Q200 qualification but meets all other electrical and mechanical specifications. This part is suitable for industrial and consumer applications where automotive certification is not required.

Compliance Verification:

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C ~ 155°C). Height variation among substitutes ranges from 0.020" to 0.028" seated height; verify PCB clearance in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF2490V replace ERJ-S06F2490V directly?

A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications (249 Ohms ±1%, 0.125W), operate across -55°C to 155°C, carry AEC-Q200 qualification, and are packaged in 0805 (2012 Metric). The primary difference is the series designation (ERJ-6EN vs. ERJ-S06). No circuit modification is required.

Q: What is the difference between 1/8W and 1/2W rated parts?

A: Power rating indicates maximum continuous power dissipation capability. A 1/8W (0.125W) part dissipates less heat than a 1/2W (0.5W) part at the same current. In the same 0805 package, higher power-rated parts (CRCW0805249RFKEAHP, RCS0805249RFKEA) provide thermal margin but are physically interchangeable. Selection depends on circuit power requirements and thermal design.

Q: Are all substitute parts AEC-Q200 qualified?

A: No. CR0805-FX-2490ELF (Bourns) does not carry AEC-Q200 qualification. For automotive applications requiring AEC-Q200 compliance, select from ERJ-6ENF2490V, AC0805FR-07249RL, CRCW0805249RFKEA, CRCW0805249RFKEAHP, RCS0805249RFKEA, or RMCF0805FT249R.

Q: Do substitute parts have different physical dimensions?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Seated height varies: ERJ-S06F2490V and ERJ-6ENF2490V measure 0.028" maximum; AC0805FR-07249RL and CR0805-FX-2490ELF measure 0.024"; CRCW0805249RFKEA, CRCW0805249RFKEAHP, and RCS0805249RFKEA measure 0.020"; RMCF0805FT249R measures 0.026". Verify clearance in height-constrained PCB designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part specification.

Q: Which substitute offers the best inventory availability?

A: RMCF0805FT249R (Stackpole) has 135,427 units in stock, followed by ERJ-6ENF2490V (Panasonic) with 218,164 units. Both provide high availability for volume production requirements.
