Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE07634RL is determined by strict adherence to the following parameters:

Primary Substitution Criteria:

• Resistance value: 634 Ohms (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Secondary Substitution Parameters (Enhancement Allowed):

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or better (±25ppm/°C or ±10ppm/°C acceptable as upgrade)
• Certifications: Additional certifications (AEC-Q200) acceptable without restriction

All four substitute parts meet these criteria. The RT0402BRD07634RL, CPF0402B634RE1, ERA-2AEB6340X, and RN73C1E634RBTDF maintain identical core electrical and mechanical specifications while offering improved tolerance and temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

Suitable for high-precision measurement and calibration circuits. Lower inventory (1,027 pcs) and REACH status listed as Vendor Undefined require verification before design lock.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RT0402FRE07634RL with any of these parts without circuit redesign?

A: Yes. All substitute parts maintain identical resistance value (634 Ohms), power rating (0.063W), package (0402), and operating temperature range (-55°C ~ 155°C). Direct PCB footprint compatibility is assured. The ERA-2AEB6340X has a maximum seated height of 0.40mm versus 0.35mm for others; verify clearance in height-constrained applications.

Q: What is the primary advantage of upgrading to ±0.1% tolerance substitutes?

A: The substitute parts reduce tolerance band from ±1% to ±0.1%, providing tighter resistance value control. This is critical in precision analog circuits, measurement instrumentation, and signal conditioning where component tolerance directly impacts circuit accuracy. The main part RT0402FRE07634RL remains suitable for general-purpose applications where ±1% tolerance is acceptable.

Q: Which substitute offers the best temperature stability?

A: The RN73C1E634RBTDF provides ±10ppm/°C temperature coefficient, compared to ±25ppm/°C for RT0402BRD07634RL, CPF0402B634RE1, and ERA-2AEB6340X. This superior stability is required in precision circuits operating across wide temperature ranges or in applications with stringent drift specifications.

Q: Is the ERA-2AEB6340X suitable for automotive applications?

A: Yes. The ERA-2AEB6340X carries AEC-Q200 automotive qualification. This certification is required for automotive-grade designs and applications subject to automotive reliability standards. The other substitutes do not carry this certification.

Q: Are all parts RoHS3 compliant?

A: Yes. All parts listed—RT0402FRE07634RL, RT0402BRD07634RL, CPF0402B634RE1, ERA-2AEB6340X, and RN73C1E634RBTDF—are ROHS3 Compliant. All carry MSL 1 (Unlimited) moisture sensitivity rating, requiring no special handling beyond standard ESD precautions.

Q: What inventory considerations should guide part selection?

A: ERA-2AEB6340X has the highest inventory (79,736 pcs), followed by RT0402BRD07634RL (10,978 pcs). CPF0402B634RE1 and RN73C1E634RBTDF have lower availability (1,426 pcs and 1,027 pcs respectively). For high-volume production, ERA-2AEB6340X or RT0402BRD07634RL are preferred. For low-volume or prototype applications, all options are viable.
