RL07S121GRE6 Equivalent & Substitute Parts

Part Overview

The RL07S121GRE6 is a 120 Ohm, 1/4W metal film axial resistor manufactured by Vishay Dale, designed for military applications per MIL-PRF-22684/01 specification. This component features flame retardant coating, moisture resistance, and safety-rated construction suitable for high-reliability electronic assemblies. The part is currently active in production with 740 units available in tape and reel packaging. Substitute parts are identified when packaging format differs or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RL07S121GRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 120 Ohms
• Tolerance: ±2%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -65°C to 175°C
• Package type: Axial
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Military series compliance: MIL-PRF-22684/01, RL07
• Feature set: Flame Retardant Coating, Military, Moisture Resistant, Safety

The RL07S121GB14 qualifies as a direct substitute based on identical electrical specifications and mechanical form factor. The only difference is packaging format: RL07S121GRE6 is supplied in tape and reel (TR) configuration, while RL07S121GB14 is supplied in bulk packaging. Both parts maintain the same base product number (RL07) and military qualification status.

Parameter Comparison

Engineering Selection Recommendations

Both RL07S121GRE6 and RL07S121GB14 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts is determined by assembly process requirements and packaging logistics:

RL07S121GRE6 is specified when automated pick-and-place assembly processes require tape and reel packaging format. This configuration supports high-volume production workflows with component feeders.

RL07S121GB14 is specified when bulk packaging is acceptable for manual assembly, kit assembly, or when tape and reel format is not required by manufacturing processes.

Both parts maintain full compliance with MIL-PRF-22684/01 military specification and are suitable for applications requiring flame retardant, moisture-resistant, safety-rated resistors across the -65°C to 175°C operating temperature range. Neither part is RoHS compliant; applications with RoHS requirements must identify alternative component families.

Frequently Asked Questions (FAQ)

Q: Can RL07S121GB14 be used in place of RL07S121GRE6 in the same circuit?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. RL07S121GB14 (bulk) can replace RL07S121GRE6 (tape and reel) provided the assembly process accommodates bulk component handling.

Q: What is the difference between tape and reel and bulk packaging?

A: Tape and reel (TR) packaging supplies components on continuous carrier tape wound on reels, designed for automated assembly equipment. Bulk packaging supplies loose components in trays or bags, suitable for manual assembly or kit applications. Electrical and mechanical specifications are identical.

Q: Are these parts interchangeable in military applications?

A: Yes. Both parts carry the same MIL-PRF-22684/01 military specification designation and RL07 series classification. They are fully interchangeable from an electrical and reliability standpoint.

Q: What does RoHS non-compliant mean for these parts?

A: These resistors do not meet Restriction of Hazardous Substances (RoHS) directives. Applications requiring RoHS compliance must specify alternative component families explicitly rated as RoHS compliant.

Q: Can these 120 Ohm resistors be used in high-temperature applications?

A: Yes. The operating temperature range extends to 175°C maximum, with temperature coefficient of ±200ppm/°C. Verify that circuit design accounts for resistance value drift across the full operating temperature range.

Q: What does Moisture Sensitivity Level 1 (Unlimited) indicate?

A: MSL 1 (Unlimited) means these components have no moisture sensitivity restrictions. They can be stored and handled without special moisture control measures or time-limited shelf life constraints.
