RT0402DRD07124RL Equivalent & Substitute Parts

Part Overview

The RT0402DRD07124RL is a 124 Ohm ±0.5% thin film chip resistor manufactured by YAGEO in the 0402 (1005 Metric) package. This component is rated for 0.063W (1/16W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent resistance values, power ratings, package dimensions, and thermal specifications align within acceptable electrical and mechanical tolerances for direct board-level replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0402DRD07124RL are qualified based on the following criteria:

• Identical resistance value: 124 Ohms
• Identical package: 0402 (1005 Metric)
• Identical power rating: 0.063W (1/16W)
• Identical composition: Thin Film
• Identical temperature coefficient: ±25ppm/°C
• Identical operating temperature range: -55°C to 155°C
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

Tolerance variations (±0.5% vs. ±0.1%) and additional certifications (AEC-Q200, Anti-Sulfur) represent upgrades or enhanced specifications. Physical dimensions remain within acceptable limits across all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain identical core electrical and mechanical specifications to the RT0402DRD07124RL. Selection among qualified substitutes depends on application requirements:

CPF0402B124RE1 (TE Connectivity Neohm series) provides improved tolerance (±0.1%) for general-purpose applications requiring tighter resistance accuracy.

ERA-2AEB1240X (Panasonic) includes AEC-Q200 automotive qualification, suitable for automotive and harsh-environment applications.

RG1005P-1240-B-T5 (Susumu) combines AEC-Q200 automotive qualification with anti-sulfur protection, appropriate for automotive and corrosive-environment applications.

All parts are ROHS3 compliant and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B124RE1 replace RT0402DRD07124RL directly?

A: Yes. Both parts share identical resistance (124 Ohms), power rating (0.063W), package (0402), composition (thin film), temperature coefficient (±25ppm/°C), and operating range (-55°C to 155°C). The CPF0402B124RE1 offers improved tolerance (±0.1% vs. ±0.5%), which is a functional upgrade.

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

A: Both parts are electrically and mechanically equivalent to the RT0402DRD07124RL. ERA-2AEB1240X carries AEC-Q200 automotive qualification. RG1005P-1240-B-T5 includes both AEC-Q200 qualification and anti-sulfur protection. Selection depends on environmental exposure requirements.

Q: Are there height differences among substitute parts?

A: The RT0402DRD07124RL and CPF0402B124RE1 have a maximum seated height of 0.014" (0.35mm). ERA-2AEB1240X and RG1005P-1240-B-T5 have a maximum seated height of 0.016" (0.40mm). This 0.002" (0.05mm) difference is within standard PCB assembly tolerances for 0402 packages.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original RT0402DRD07124RL specification.

Q: Can I use ERA-2AEB1240X in a non-automotive application?

A: Yes. AEC-Q200 qualification is a superset of standard commercial specifications. Parts qualified to AEC-Q200 standards are suitable for any application within their electrical and thermal ratings.
