Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402BRE07124RL is determined by the following mandatory parameters:

• Resistance value: 124 Ohms
• Tolerance: ±0.1%
• Power rating: 0.063W (1/16W) minimum
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 Compliant
• MSL rating: Level 1 or better

All identified substitute parts meet these core electrical and mechanical requirements. Differences in temperature coefficient, height-seated maximum, and optional certifications (such as AEC-Q200 automotive qualification) represent secondary variations that do not affect fundamental substitutability within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and ROHS3 compliance with Level 1 MSL rating, ensuring compatibility within the specified parameter envelope.

CPF0402B124RE1 (TE Connectivity Passive Product) offers improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C) with identical height-seated maximum, providing enhanced stability in precision applications without package height constraints.

ERA-2AEB1240X (Panasonic Electronic Components) and RG1005P-1240-B-T5 (Susumu) both carry AEC-Q200 automotive qualification with ±25ppm/°C temperature coefficient. ERA-2AEB1240X is suitable for general automotive applications. RG1005P-1240-B-T5 adds anti-sulfur protection, addressing corrosive environments and extended reliability requirements in automotive or industrial settings. Both parts have maximum seated height of 0.016" (0.40mm), requiring verification against PCB layout constraints if height-sensitive applications are present.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRE07124RL be directly replaced with CPF0402B124RE1?

A: Yes. Both parts share identical resistance (124 Ohms), tolerance (±0.1%), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). CPF0402B124RE1 features improved temperature coefficient (±25ppm/°C) and identical height-seated maximum (0.014"), making it a direct electrical and mechanical substitute.

Q: What is the difference between ERA-2AEB1240X and RG1005P-1240-B-T5?

A: Both parts are AEC-Q200 qualified with ±25ppm/°C temperature coefficient and 0.016" (0.40mm) maximum seated height. RG1005P-1240-B-T5 includes anti-sulfur protection for enhanced environmental resistance. Selection depends on application requirements for corrosive environment protection.

Q: Are there height constraints when substituting with ERA-2AEB1240X or RG1005P-1240-B-T5?

A: Yes. ERA-2AEB1240X and RG1005P-1240-B-T5 have maximum seated height of 0.016" (0.40mm), compared to 0.014" (0.35mm) for RT0402BRE07124RL and CPF0402B124RE1. PCB layout and component clearance must be verified before substitution.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: Yes. All parts are ROHS3 compliant with MSL Level 1 (Unlimited) rating, ensuring equivalent environmental and moisture sensitivity protection.

Q: Which substitute part is recommended for automotive applications?

A: ERA-2AEB1240X and RG1005P-1240-B-T5 both carry AEC-Q200 automotive qualification. RG1005P-1240-B-T5 is recommended for applications requiring anti-sulfur protection in corrosive environments.
