Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF4870U is determined by strict equivalence across the following parameters:

• Resistance value: 487 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these criteria. Variations in product status and inventory availability do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts are electrically and mechanically equivalent. Selection should be based on product status and supply availability:

ERJ-S1TF4870U remains the primary choice as an active production component with full automotive qualification and anti-sulfur protection.

ERJ-1TNF4870U is marked as "Not For New Designs" and should be reserved for legacy system maintenance or replacement applications only, despite higher inventory availability.

CRCW2512487RFKEG from Vishay Dale is an active production alternative with equivalent specifications and the highest current inventory level, suitable for applications where multi-source qualification is required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF4870U be used in new designs? A: No. This part carries a "Not For New Designs" status and is intended for legacy system support only. Use ERJ-S1TF4870U or CRCW2512487RFKEG for new designs.

Q: Are there dimensional differences between the Panasonic and Vishay Dale parts? A: Both parts use the 2512 (6432 Metric) package. The Panasonic ERJ-S1TF4870U specifies 0.252" L x 0.126" W (6.40mm x 3.20mm), while the Vishay Dale CRCW2512487RFKEG specifies 0.248" L x 0.124" W (6.30mm x 3.15mm). Both have identical maximum seated height of 0.028" (0.70mm) and are footprint-compatible for standard PCB layouts.

Q: Do all substitute parts meet AEC-Q200 automotive qualification? A: Yes. All three parts carry AEC-Q200 rating and are suitable for automotive applications.

Q: What is the significance of anti-sulfur protection on the ERJ-S1TF4870U? A: Anti-sulfur protection is a feature of the ERJ-S1TF4870U. The ERJ-1TNF4870U and CRCW2512487RFKEG do not list this feature. For applications in high-sulfur environments, the ERJ-S1TF4870U is the specified choice.

Q: Are all parts RoHS3 compliant? A: Yes. All three parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.
