Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0402FRE0763R4L are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 63.4 Ohms
• Package type: 0402 (1005 Metric)
• Power rating: 0.063W minimum
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1%
• Temperature coefficient: May be equal to or lower than ±50ppm/°C
• Mechanical dimensions: Within standard 0402 specifications

Compliance Requirements:

• RoHS3 compliance maintained
• MSL 1 rating or equivalent
• Active product status

Two substitute parts meet these criteria with improved tolerance specifications and enhanced reliability features.

Parameter Comparison

Engineering Selection Recommendations

CPF0402B63R4E1 (TE Connectivity Passive Product): This substitute provides improved tolerance of ±0.1% compared to the original ±1%, with a reduced temperature coefficient of ±25ppm/°C. The part maintains ROHS3 compliance and MSL 1 rating. Selection is appropriate for applications requiring tighter resistance tolerance without automotive-specific requirements. Inventory availability is 1418 pieces.

ERA-2AEB63R4X (Panasonic Electronic Components): This substitute offers the same ±0.1% tolerance and ±25ppm/°C temperature coefficient as the TE Connectivity option, with the addition of AEC-Q200 automotive qualification. The part is ROHS3 compliant with MSL 1 rating. Selection is appropriate for automotive applications or systems requiring automotive-grade component reliability. Inventory availability is 14865 pieces, providing superior supply continuity.

Both substitutes are electrically and mechanically compatible with the RT0402FRE0763R4L within the 0402 package footprint and maintain all required compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B63R4E1 or ERA-2AEB63R4X be used as direct replacements for RT0402FRE0763R4L?

A: Yes. Both substitutes share identical resistance values (63.4 Ohms), power ratings (0.063W), package types (0402), and operating temperature ranges (-55°C to 155°C). The substitutes feature improved tolerance (±0.1% vs. ±1%) and lower temperature coefficients (±25ppm/°C vs. ±50ppm/°C), making them functionally superior for direct PCB replacement without design modification.

Q: What is the difference between the two substitute parts?

A: The primary difference is automotive qualification. ERA-2AEB63R4X carries AEC-Q200 certification, qualifying it for automotive applications. CPF0402B63R4E1 is a standard industrial-grade component. Both offer identical electrical specifications and tolerance performance. Selection depends on application requirements and supply chain preferences.

Q: Are there any mechanical compatibility concerns?

A: No. All three parts conform to the 0402 (1005 Metric) package standard with compatible footprints. Maximum seated heights are 0.014" (RT0402FRE0763R4L and CPF0402B63R4E1) and 0.016" (ERA-2AEB63R4X), both within standard 0402 specifications. PCB layout and assembly processes require no modification.

Q: Do the substitute parts maintain RoHS and MSL compliance?

A: Yes. Both CPF0402B63R4E1 and ERA-2AEB63R4X are ROHS3 compliant with MSL 1 (Unlimited) ratings, matching the original RT0402FRE0763R4L specifications.

Q: Which substitute should be selected for cost optimization?

A: CPF0402B63R4E1 provides improved specifications at a standard industrial grade. ERA-2AEB63R4X is appropriate when automotive qualification is required or when supply continuity is prioritized (14865 pieces vs. 1418 pieces available).
